6Р82Ш universal cantilever milling machine. Purpose and scope

6Р82Ш milling machine has been produced since 1972 and replaced the outdated 6М82Ш model in production and was replaced by a more advanced model 6Т82Ш.

Machines of the 6Р83Ш model differ from the 6Р82Ш by the increased size of the work table and a more powerful main movement motor.

The table of the universal cantilever milling machine model 6Р82Ш is non-rotating.

The highly versatile cantilever milling machine 6Р82Ш is designed to perform a variety of milling work, mainly in the manufacture of metal models of stamps and molds for work in serial and individual production.

Operating principle and design features of the machine

The advantage of widely universal milling machines is the ability to process a workpiece from different sides from one installation, which is very important in tool, repair and pilot production, where installation, alignment and fastening of the workpiece takes a lot of time and requires highly qualified workers.

To process various types of surfaces, as well as large-sized models that exceed the dimensions of the table, the spindle head is mounted on a retractable trunk and can be rotated at an angle in two mutually perpendicular planes.

6Р82Ш machine is equipped with a horizontal spindle, which can be used when processing planes with end and cylindrical cutters.

Both separate and simultaneous operation of two spindles is provided. When installing the earrings supplied with the machine, the machine can be used as a horizontal milling machine.

To expand the capabilities of the machine, in addition to the earrings, an additional overhead rotating head is included. The overhead head allows you to process large parts, as well as perform simple boring work.

The presence of a backlash sampling mechanism in the screw pair of the longitudinal feed of the table allows for up and down milling both in simple modes and in modes with automatic cycles.

Milling of gears, reamers, cam contours and other parts that require periodic or continuous rotation around their axis is carried out on these machines using a dividing head or an overhead round table.

Lubrication of the console guides and the table-slide assembly is carried out centrally from a plunger pump. Thanks to effective lubrication, the durability of these components increases, the original accuracy is maintained longer and maintenance time is reduced. The roughness of the treated surface is Rz 20 µm. Machine accuracy class P.

6Р82Ш machine is designed for milling all kinds of parts made of steel, cast iron and non-ferrous metals using cylindrical, disk, shaped, corner, face, end and other cutters. The ability to configure the machine for various semi-automatic and automatic cycles allows you to successfully use the machines to perform operational work in production and automatic lines in large-scale production.

The machine can process vertical and universal planes, grooves, corners, frames, gears, etc.

The technological capabilities of the machine can be expanded with the use of a dividing head, a rotary round table, an overhead universal head and other devices.

The design features of the machine are:

  • wide ranges of table feed values;
  • quick-change tool mount;
  • presence of a feed slowdown mechanism;
  • slowing down the working feed in the automatic cycle;
  • ability to work in automatic cycles, including frame processing;
  • automatic lubrication of components;
  • the use of non-contact high-speed electromagnetic clutches in the feed drive;
  • increased accuracy of the machine due to the location of the cross-feed screw along the axis of the cutter;
  • the ability to move the table simultaneously in two and three coordinates;
  • the possibility of using a DC electric motor in the feed drive;
  • possible further automation of machines through the use of digital display and operational control devices;

6Р82Ш machines are designed to perform various milling operations in both individual and large-scale production. In conditions of large-scale production, machines can also be successfully used to perform operational work.

The technical characteristics and high rigidity of the machines allow full use of the capabilities of both high-speed and carbide tools.

To reduce auxiliary time and ease of control, the machines provide:

  • duplicated push-button-handle control (front and left side of the machine)
  • starting and stopping the spindle and turning on the high speeds of the machine using buttons
  • control of table movements from handles, the direction of rotation of which coincides with the direction of movement of the table
  • changing speeds and feeds using single-handle selective mechanisms, allowing you to obtain any speed or feed by turning the dial without going through intermediate steps
  • DC braking

The machines are automated and can be configured for various automatic cycles, which increases labor productivity, eliminates the need to maintain the machines by highly qualified workers and facilitates the possibility of organizing multi-machine maintenance.

Machine accuracy class P according to GOST 8-77.

Design features


Appearance

Milling and processing equipment of the 6Р82Ш brand was developed and produced at the Gorky Milling Machine Plant. This enterprise is the oldest and, thanks to the accumulated experience, the machines manufactured there are characterized by good operational and technical parameters.

A feature of the widely-universal milling equipment is the ability to simultaneously process the workpiece on both sides. This allows you to increase productivity, since you do not need to change the position of the workpiece on the work table to perform another operation.

Additionally, the following characteristics can be highlighted:

  • presence of a horizontal spindle. It can be used to perform machining with cylindrical and end mills;
  • additional earring adapters. After their installation, it becomes possible to perform horizontal milling operations;
  • rotating overhead head. With its help, large parts are processed and boring work is performed;
  • possibility of installing an overhead table and dividing head.

To automate the production process, you can choose manual, semi-automatic or automatic operating mode. Quick replacement of the cutter is carried out using a quick-change mechanism. Also, the 6Р82Ш machine has a wide range of work table offsets.

The working head quickly stops due to DC braking. This increases productivity because it takes less time to change cutting tools.

Kinematic diagram of the milling machine 6р82ш

The gearbox allows you to select the required speed without sequentially passing through intermediate stages.

Rack 19 (Fig. 10), moved by shift handle 18, by means of sector 15 through fork 22 (Fig. 11) moves the main roller 29 with shift disk 21 in the axial direction. The shift disk can be turned with the speed indicator 23 through bevel gears 28 and 30. The disk has several rows of a certain size of holes located against the pins of the racks 31 and 33. The racks engage in pairs with a gear 32. A shift fork is attached to one of each pair of racks. When moving the disk by pressing on the pin of one of the pair, reciprocating movement of the slats is ensured.

In this case, the forks at the end of the disk stroke take a position; corresponding to the meshing of certain pairs of gears. To eliminate the possibility of hard stop of the gears when switching, the pins of 20 racks are spring-loaded.

Fixation of the dial when choosing a speed is ensured by ball 27, which slides sprocket 24 into the grooves.

The spring 25 is adjusted by plug 26, taking into account the precise fixation of the dial and the force when turning it.

Handle 18 (see Fig. 10) is held in the on position by spring 17 and ball 16. In this case, the handle tenon fits into the groove of the flange.

Correspondence of speeds to the values ​​​​indicated on the indicator is achieved by a certain position of the bevel wheels 28 and 30 (see Fig. 11) along the mesh. Correct engagement is established by cores at the ends of the mating tooth and cavity or by setting the pointer to the speed position of 31.5 rpm and the disk with forks to the speed position of 31.5 rpm. The gap in the engagement of the conical pair should not be more than 0.2 mm, since the disk can rotate up to 1 mm due to this.

The gearbox is lubricated by the gearbox lubrication system by spraying oil coming from a tube at the top of the frame. Lack of oil rain can cause unacceptable heating of the shift fork jaws and lead to fork binding, deformation or failure.

The connector plane is sealed with a gasket or gasoline-resistant grease. GOST 7171-63.

Kinematic diagram

The sequence of movements of all parts of the drive of the 6Р82Ш milling machine is determined by the interaction of its main components. The main working movements are the movement of the tool head with spindles and the table feed movement. The feedbox of a machine is characterized by a certain combination of rotation speed steps (18 in total). In this case, the lowest rotation speed is 0.52 s-1, and the highest is 26.6 s-1. In turn, the machine spindles are driven by their own electric motor using gears. The number of speeds is 12, with the lowest and highest speeds being 0.83 s-1 and 26.6 s-1, respectively.

A separate branch of the kinematic diagram is the drive of the table movement mechanism in the transverse and longitudinal directions. The movement from a separate electric motor is transmitted through the clutch to gears. Due to the presence of different combinations of gear pairs, the range of possible horizontal feed speeds is from 25 to 2500 mm/min. Rapid feed is also possible - 3000 mm/min. In the vertical direction, the highest feed speed is 416 mm/min, and the lowest is 8.3 mm/min, with a feed speed in the installation (adjustment) mode of 1000 mm/min.

The kinematic diagram of the machine provides for electromechanical blocking from the simultaneous activation of several feeds of the work table.

Main components and mechanisms of the 6Р82Ш milling machine

The trunk 5, in which the gearbox of the spindle drive of the rotary head 6 is mounted, moves along the guides of the frame 1 (Fig. 121) by rotating the flywheel 15 (Fig. 120) with the clamp 39 released.

Gearbox for console milling machine 6Р82Ш

Gearbox for console milling machine 6р82ш

Spindle 11 of the machine (Fig. 123) is mounted on bearings 4, 2, 12. The axial clearance in the spindle is adjusted by grinding rings 9,10. Increased clearance in bearing 4 is eliminated by grinding half rings 5 ​​and nut 1 as follows. Remove cover 3 (or side cover), flange 6, spring ring 7, rings 8 and take out half rings 5. Using nut 1, select the gap so that during operation the heating of the bearings does not exceed 60 ° C. Measure the size of the gap between the bearing and the spindle collar and Accordingly, the half rings 5 ​​are polished. Then the half rings are installed and parts 6, 8, 7, 3 are mounted.

The gearbox (Fig. 124) allows you to select the required speed without sequentially passing through intermediate stages. Rack 1 (Fig. 124, a), moving by means of a handle through gear sector 2 and fork 10 (Fig. 124, 6), moves the main roller 3 with shift disc 9 in the axial direction using gear 2 and bushing 4. On the disc There are several rows of holes located opposite pins 8 of racks 5 and 7, connected in pairs to wheel 6. A shift fork is attached to one of each pair of racks. The slats move when the disk is pressed on the pins. At the end of the disk stroke, the forks occupy a position corresponding to the engagement of certain pairs of gears. When selecting speeds, the dial is fixed by ball 1 (Fig. 124, b), which falls into the grooves of sprocket 11. Handle 5 (Fig. 124, a) is fixed when turned on by ball 3 and spring 4; in this case, the handle tenon fits into the groove of the flange.

The horizontal spindle gearbox is located in the frame and connected to the electric motor shaft by an elastic coupling.

Rotating head of the console milling machine 6Р82Ш

Rotating head of the cantilever milling machine 6р82ш

The rotating head (Fig. 125) is mounted on the trunk through the intermediate plate using bolts inserted into the annular T-shaped groove and centered in the annular recess. The spindle 8, mounted in the sliding sleeve 9, receives rotation from the gearbox through the cam clutch 1 and conical wheels 4, 2 and 5, 4. Wheels 7 and 3 are used to adjust the axial clearance in the bearings and spindle, and half rings 2 and nut 6 - to eliminate the gap in the front bearing. The sleeve is advanced using a handwheel.

The overhead head (Fig. 126) is mounted on the rotary head with bolts entering the T-shaped groove and firmly fixed. Spindle 5 receives rotation from spindle 1 of the rotary head through bevel gears 3, 4. Nut 2 adjusts the clearance in the spindle bearings.

Feed box for cantilever milling machine 6Р82Ш

Feed box for cantilever milling machine 6р82ш

The feed box (Fig. 127, a) provides working feeds and installation movements of the table, slide and console by switching gear blocks and transmitting rotation to input shaft B through a ball safety clutch, cam clutch 4 and bushing 3, connected by a key to clutch 4 and shaft B. Stopper 1 rigidly fixes the position of nut 15. When the feed mechanism is overloaded, the balls in contact with the hole of clutch 2 compress the springs and come out of contact. In this case, wheel 14 slips relative to clutch 2, and the working feed stops.

Rapid rotation is transmitted from the electric motor (bypassing the gearbox) to gear C, which is installed on the shank of the friction clutch housing 9 and has a constant rotation speed. Nut 10 must be tightened. Housing 9 rotates freely. The friction disks are connected (one by one) to the housing 9 and the sleeve 12 connected to shaft B. When the clutch 4 is pressed onto the end of the sleeve 5 and then onto the nut 11, the disks 7 and 8 are connected and transmit rapid rotation to shaft B and gear A. Compression force disks 7 and 8 are adjusted using pin 6. Movement from shaft B to the driven shaft is carried out through a cam clutch 13.

The feed switching mechanism (Fig. 127, b) is included in the feed box assembly. The principle of operation of the mechanism is similar to the operation of a gearbox. When turned on, roller 1 is locked by balls 6 and bushing 2, which prevents disk 9 from moving in the axial direction. When you press button 4, the balls fall into the annular groove of roller 3 and roller 1 is released from fixation. Shift disk 9 is secured against rotation by ball 8 through bushing 5, connected by a key to ball 1. Screw 7 adjusts the spring tension.

Console of cantilever milling machine 6Р82Ш

Console of cantilever milling machine 6Р82Ш

The console (Fig. 128) combines the nodes of the machine feed chain. It contains shafts and gears that transmit movement from the feed box in three directions (to the longitudinal, transverse and vertical feed screws); mechanism for switching on transverse and vertical feeds. Gear 8 rotates from wheel A (Fig. 127, a) and transmits movement to gears 7, 4, 2, 1 (Fig. 128, a). Wheel 8 can transmit movement to the shaft only through cam coupling 6. Then, through cylindrical and bevel gears, the movement is transmitted to screw 16 (Fig. 128, b). The engagement of the pair 16 and 10 is adjusted by compensators 14, 15 and fixed with a screw inserted into pin 13. Bushing 11 is not dismantled; the vertical movement nut is fixed in the column. Wheel 2 rotates the shaft IX of the longitudinal chain through a key and splines. The cross feed screw X rotates from wheel 2 and wheel 1, which is freely seated on the shaft, when the cross feed clutch is engaged. Shafts XII and XIII are dismantled when removing the stoppers at wheels 8, 9.

Mechanism for switching on installation movements of the 6Р82Ш cantilever milling machine

Mechanism for switching on installation movements of the 6р82ш milling machine

The slide is dismantled after removing shaft IX, for which you need to remove the upper shield on the console guides, knock out pin 3 and remove shaft IX. The mechanism for activating the installation movements (Fig. 129) turns on the clutch and compresses the friction clutch discs. Lever 1 is pinned on axis 4. The latter is pressed in the direction of the frame mirror by spring 6. The right nuts 2 serve to adjust the spring force, the left nuts 3, resting against the end of the sleeve 5, regulate and limit the stroke of the axis. The shoulder of lever 1 rests on cam 7. Lever 1, when turning cam 7, moves, compressing spring 6. The second end of axis 8 has a fine tooth, which ensures the installation of lever 9, which connects axis 8 at a slight angle to the electromagnet rod. The latter is connected through a rod and a hinge to a fork, from which, through a nut and a spring, the force is transmitted to lever 9. Thus, regardless of the force of the electromagnet, the force on the lever is determined by the degree of compression of the spring.

The mechanism for switching on the transverse and vertical feeds (Fig. 130) controls the switching on and off of the cam clutches of the transverse and vertical feeds from the feed electric motor. Made in a separate building. When the handle 5 moves up, down, left, right, the drum 1 associated with it makes the corresponding movements and, with its bevels, through the lever system controls the activation of the cam clutches, and through the pins - the limit switches intended for reversing the feed motor. The drum is connected by rod 2 with a backup handle. When the transverse stroke is turned on and off, the rod moves translationally, and when the vertical stroke is turned on, it rotates. Screw 4 and nut 3 are used to eliminate gaps in the system.

The lead screw 1 (Fig. 131) of the table receives rotation through the sliding key of the sleeve 9, located in the bushings 5, 7. The sleeve 9 rotates from the cam coupling 6 through the splines when it engages with the cams of the sleeve 5, connected to the bevel gear 4. On the sleeve 5 there is a gear ring, which is in mesh with the gear wheel of the round table drive. Clutch 6 has a toothed ring for rotating the longitudinal feed screw from the handwheel. The slide is clamped to the guide console by faceplate 8. Wheel 9 (Fig. 132) is spring-loaded in case of tooth contact with tooth. Engagement of the wheels is only possible when coupling 6 and bushing 5 are disconnected. This blocks the flywheel during mechanical feeds. Nuts 2 and 3 of the lead screw (Fig. 131) are located on the left side of the slide. The gap in the console and slide guides is selected using wedges.

Mechanism for switching on the longitudinal feed of the 6Р82Ш cantilever milling machine

Mechanism for switching on longitudinal feed of milling machine 6р82ш

The mechanism for turning on the longitudinal feed (Fig. 132) turns on the longitudinal stroke clutch, turns on and reverses the feed motor. Handle 4 is fixedly connected to axis 2 by turning lever 1, along the curved surface of which roller 15 rolls when switching (Fig. 132). In the neutral position of the lever 10, the roller is located in the middle cavity; when it is turned on, it is in one of the side depressions. The movement of roller 15 through lever 16 is transmitted to rod 5 through wheel 7—rack 6 and fork 8 driving clutch 6 (Fig. 131). Spring 2 (Fig. 132) constantly presses on rod 5. Spring 4 ensures that the handle is turned on when a tooth hits the tooth of coupling 6. Spring 4 is adjusted by screw 3 through the hole in plug 1.

On the same axis with the lever 16 there is a lever 18, which serves to engage the clutch 6 with a cam 19 attached to the rod 20 connecting the main longitudinal stroke handle with the backup one. The limit switch 17 turns on and reverses the feed motor. It is turned off after clutch 6 is turned off. On the hub 5 (Fig. 133) of the longitudinal stroke handle there are protrusions that are acted upon by the longitudinal stroke limiting cams or (in automatic cycles) the longitudinal stroke control cams. The operation of the limit switches is checked with cover 14 removed (Fig. 132).
