Operation and repair, passport

The mechanism itself requires installation on a concrete foundation with a thickness of at least 30 cm. In this case, the surface must be perfectly flat. This will reduce the risk of inaccuracies during fine milling.

During initial start-up, be sure to fill the lubrication system reservoir with oil. Once a year you need to flush the oil reservoir. In case of any malfunction, the machine should be turned off and a technician should inspect it. Any part in the machine must be replaced when worn out, so the unit itself does not have a service life.

General appearance and design

The unit is distinguished by the adhesion strength of individual components and their independent control. The cast base gives the machine stability. The ability to fine tune gives the ability to mill small parts.

Location and description of components

Main design elements:

1. Bed. Wide rectangular platform on pins with a vertical neck.
2. Spindle head and sleeve. A rotary mechanism fixed in the annular recess of the frame, with a motor for clamping the cutting part.
3. Control cabinet. Includes an electric drive for spindle movement, a gearbox, a control panel and several separate switches.
4. Front console. Table guide motor and devices for regulating their movement.

The weight of the assembled machine is 4300 kg, height 2430 mm, width 2252 mm. Total length 2570 mm. The travel of the working surface is up to 1 m from right to left, up to 40 cm in the transverse plane and up to 43 cm in the vertical.

Location of controls

The main movement is controlled by a gearbox, which includes 18 spindle speeds. Adjustable using a handle with corresponding divisions. The position of the head is ensured by a rotary hexagon and a flywheel for mechanical extension of the sleeve. A separate handle is provided for clamping the sleeve.

The feed drive controls table movements through normal and high speed clutches. When you select one of these modes, the other is blocked. The drive box allows for 18 different feeds. For precise preliminary positioning of the workpieces, mechanical clamps of the table and console slides are provided on the frame guides. Each working element is equipped with a manual flywheel.

Control panels

The 6T13 machine has two operator consoles - a side one on the wall of the control cabinet, and a main one on the table console. As well as a panel for selecting automatic cycles. The speed and direction of feeds are regulated from the main one, the movement of the spindle head from the side. Buttons for basic actions - start, stop, enabling fast movement mode or slow feeds - are duplicated on both panels.

The key for turning on the machine, as well as changing the direction of rotation of the cutter, is located on the rear wall of the device. But there is an emergency shutdown button on the main remote control. It also switches the cooling mode on and off. The remote control is selected using a switch on the side.

Features of the structure of the rotary head

The mechanism for rotating the spindle is a system of conical rings, half rings and gears, and is attached to the frame flange with bolts. Guide sleeves are fixed to the rotating head, inside which there is a double-support spindle shaft on bearings. In the upper part of the sleeve there is a drive for the cutting tool clamp. To avoid injury, spindle rotation is blocked without first fixing the cutter.

If necessary, the head design allows you to adjust the axial and radial play of rotation. For this purpose, there is a removable plug on its body. Through this hole, the size of the play between the bearing and the spindle cylinder is measured. The adjustment is carried out by grinding the axial and radial half rings.

Kinematic diagram of the 6T13 cantilever milling machine

Kinematic diagram of the 6T13 cantilever milling machine

The kinematic diagram is given to understand the connections and interactions of the main elements of the machine. The numbers of teeth (g) of the gears are indicated on the callouts (the asterisk indicates the number of starts of the worm).

The main movement is driven by a flange electric motor through an elastic coupling.

The spindle speed is changed by moving three toothed blocks along the splined shafts.

The gearbox provides the spindle with 18 different speeds.

The feed drive is carried out from a flange electric motor mounted in the console. By means of two three-crown blocks and a movable gear wheel with a cam clutch, the feed box provides 18 different feeds, which are transmitted through a ball safety clutch to the console and then, when the corresponding cam clutch is engaged, to the screws of longitudinal, transverse and vertical movements.

Accelerated movements are obtained when the high-speed clutch is turned on, the rotation of which is carried out through intermediate gears directly from the feed electric motor.

The clutch is interlocked with the working feed clutch, which eliminates the possibility of their simultaneous activation.

Graphs explaining the structure of the machine feed mechanism are shown in Fig. 6 and 7. For machines of models 6T13B (Fig. 7) vertical feeds are 3 times less than longitudinal ones.

Design of the main components of the 6T13 cantilever milling machine

bed

The bed is the base unit on which the remaining components and mechanisms of the machine are mounted.

The frame is rigidly fixed to the base and fixed with pins.

Rotating head of the 6T13 cantilever milling machine

The rotating head (Fig.) is centered in the annular recess of the bed neck and is attached to it with four bolts that fit into a single groove in the bed flange.

The spindle is a two-support shaft mounted in a retractable sleeve. The axial play in the spindle is adjusted by grinding rings 3 and 4. Increased play in the front bearing is eliminated by grinding half rings 5 ​​and tightening the nut.

The adjustment is carried out in the following order:

• the spindle sleeve extends;
• flange 6 is dismantled;
• half rings are removed;
• a screw plug is removed from the right side of the head body;
• through the hole, unscrewing screw 2 unlocks nut 1;
• Nut 1 is locked with a steel rod. By turning the spindle by the nut, the nut is tightened and this moves the inner race of the bearing. After checking the play in the bearing, the spindle is run in at maximum speed. When operating for an hour, the heating of the bearings should not exceed 60° C;
• the size of the gap between the bearing and the spindle collar is measured, after which the half rings 5 ​​are ground to the required amount;
• the half rings are put in place and secured;
• Flange 6 is screwed in.

To eliminate radial play of 0.01 mm, the half rings must be ground by approximately 0.12 mm.

Rotation is transmitted to the spindle from the gearbox through a pair of bevel and a pair of cylindrical gears mounted in the head.

The bearings and gears of the rotary head are lubricated from the frame pump, and the spindle bearings and the sleeve moving mechanism are lubricated by extrusion.

Gearbox

The gearbox is mounted directly in the frame body. The connection of the box to the electric motor shaft is carried out by an elastic coupling, which allows misalignment in the motor installation of up to 0.5-0.7 mm.

The gearbox can be inspected through the window on the right side.

The gearbox is lubricated by a plunger pump (Fig. 9), driven by an eccentric. Pump capacity is about 2 l/min. Oil is supplied to the pump through a filter. From the pump, the oil flows to the oil distributor, from which it is discharged through a copper tube to the pump control eye and through a flexible hose to the rotary head. The gearbox elements are lubricated by splashing oil coming from the holes in the oil distributor tube located above the gearbox.

Gearbox

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

Rack 19 (Fig. 10), moved by shift handle 18, through sector 15 through fork 22 (Fig. 11) moves the main roller 29 with shift disc 21 in the axial direction.

The shift disk can be turned by the speed indicator 23 through the bevel gears 28 and 30. The disk has several rows of holes of a certain size located against the pins of the racks 31 and 33.

The racks engage in pairs with 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 occupy a position corresponding to the engagement 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 into the groove of sprocket 24.

The spring 25 is adjusted by the plug 26, taking into account the clear fixation of the dial and the normal 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 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 (for machine models 6Т13Б the corresponding speed is 50 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 from the gearbox lubrication system by splashing oil.
