Single-column turning lathe 1516. Purpose and scope

The single-column rotary lathe model 1516 is a universal machine and is designed for processing a variety of products made of ferrous and non-ferrous metals in small-scale and mass production.

Model 1516 is common among rotary lathes in the former USSR. The machine allows turning parts with a diameter of up to 1600 mm, a height of up to 1 meter and a weight of up to 6300 kg . The machine was exported to many countries around the world.

The design of the 1516 machine is unified with the design of the 1512 machine and differs only in the dimensions of the faceplate and the power of the electric motor.

The machine can perform cylindrical and conical turning and boring, turning of planes, drilling, countersinking and reaming of holes, as well as semi-finishing and finishing turning of flat end surfaces.

Operating principle and design features of the machine

The machine has two supports :

vertical with a five-position turret with automatic rotation and locking at each position
horizontal (side) with four-position tool holder

The technological capabilities of the machine are significantly expanded with the help of a self-centering faceplate supplied upon special order, devices (for thread cutting, processing of conical surfaces, turning shaped surfaces of bodies of revolution along a copier, processing parts on stops) and a device for processing with cooling.

The following operations can be performed on the machines:

turning cylindrical and conical surfaces;
boring of cylindrical and conical surfaces;
turning flat end surfaces using vertical and lateral supports.

In addition, a vertical support can be used to grind flat end surfaces while maintaining a stepwise constant cutting speed in finishing and semi-finishing modes; drilling, countersinking and reaming; Grooving and parting.

When using special devices and devices that are supplied with the machines upon special order for an additional fee, the machines can produce:

processing of parts according to specified dimensions (on stops);
cutting threads, turning and boring conical surfaces;
processing of shaped surfaces of bodies of rotation using a copier (electrocopier);
processing of parts with cooling.

In the usual version, the machines are supplied with a vertical turret support, which has a mechanical rotation and clamping of the turret head, and a side support.

In addition, upon special order, for an additional fee, a machine with a self-centering faceplate with manual clamping of the product can be supplied.

All accessories can be mounted on the machine at the same time, with the exception of cooling, which cannot be installed simultaneously with the self-centering faceplate.

Due to the fact that the installation of fixtures requires significant changes and modifications to the machine, orders for the manufacture of fixtures for previously supplied machines cannot be fulfilled. Accessories are supplied only with the machine.

The significant power of the main drive electric motor, the high rigidity of the base parts and the sufficient strength of all elements of the kinematic chain, combined with wide ranges of control of the faceplate speeds and feed rates, allow the machines to perform highly productive work at high-speed cutting conditions.

A distinctive feature of the design of the machines is that most assembly units are made as independent products, which facilitates assembly not only during the manufacturing process, but also during repairs.

Location of components

The supporting structure of the entire machine, on which all the main components of the unit are mounted, including the body - a large, heavy hollow cast frame. The machine must be secured to a thick foundation layer, which will eliminate unnecessary vibration and allow it to support the weight of the unit.

Flat guides are located on the front side of the bed. The caliper and cross member move along these structures. The main drive gearbox is located on the other side of the frame. Devices for moving the crossbar are located on the top of the frame.

The assembly of the entire rotational system is located on the table body. It is based on:

Faceplate. During the working process, it rests on circular guides, which are located in the upper part of the body. There are T-shaped grooves on the front part of the faceplate. The workpiece being processed is attached to them using additional equipment. The faceplate itself has a built-in workpiece clamping mechanism. The quality of processing and the safety of the entire work process depend on this module.
Spindle. The upper part is fixed to the center of the faceplate. It rests on the angular contact bearing from below. The function is to transmit, the main movement is from the drive.
The faceplate drive is designed to transmit, to impart movement to the spindle.

For the vertical arrangement of machine parts there is a stand with a crossbar. The manufacturer has provided for emergency situations, so the stand is made with a safety margin.

A traverse with two calipers moves along the racks, which is easy to fix in the desired position. One of the calipers is a revolving caliper, and the second is a boring caliper. The turret contains a carriage and a slider with a turret head. On the second support there is a slider with a tool holder.

Kinematic diagram of machine 1516

Kinematic diagram of rotary lathe 1516

The kinematic diagrams of machines 1512 and 1516 are similar to each other and differ from each other only in the kinematics of the chain of the feed motion transmission mechanism and the number of teeth of the table gears.

Due to the different number of teeth on the table gears, machines 1512 and 1516 have different speed limits for the faceplate speeds with the same gearbox.

The kinematics of the chains of the feed motion transmission mechanism are different for the machines, but their gear ratios are selected in such a way that the total gear ratio of the kinematic chain from the faceplate to the feed box is the same for both machines. This allows you to use the same feed boxes and obtain the same feed amounts.

Gearbox of machine 1516

The gearbox is used to ensure rotation of the faceplate, as well as starting, stopping and changing speeds. Rotation is transmitted to the input shaft of the gearbox from the main drive electric motor through a V-belt drive. The gearbox provides the faceplate with 18 speed levels.

The gearbox is controlled remotely from a pendant remote control.

The presence of electromagnetic clutches in the gearbox allows you to switch speeds on the go and thereby ensure the maintenance of a stepwise constant cutting speed when processing end surfaces.

The gearbox has six shafts mounted on rolling bearings in a housing with a parting plane along the shaft axes for ease of assembly.

At higher speeds, the start is carried out in stages in two, three or four stages. The number of acceleration stages increases with increasing speed of the faceplate.

Switching of clutches during stepwise acceleration is carried out automatically (for a detailed description, see Part 2 of the Operating Manual 'Electrical equipment of machine tools').

Changing the speed from 1st to 12th stage is carried out by turning on the corresponding combinations of electromagnetic clutches.

To enable the jog mode of operation of the faceplate, which is used when installing and aligning the part, it is necessary to place the switch on the pendant control panel in the “Jog start” position of the faceplate and press the “Start” button of the faceplate.

There are no special braking devices in the gearbox, and the faceplate is braked by simultaneous activation of three electromagnetic clutches.

Machine table

There are no fundamental design differences between the tables of machines 1516 and 1512. The machine parts are similar and differ from each other only in size.

The table consists of a body with circular guides, a faceplate with a spindle and a faceplate drive.

The table body is a cast iron with a developed system of ribs, giving it greater rigidity.

At the top of the table body there are annular projections that fit into the annular grooves of the faceplate, forming a labyrinth. This prevents lubricant from splashing and protects against chips, cast iron dust, emulsion and other contaminants getting inside the table.

The faceplate is driven from the gearbox through a pair of bevel gears with a circular tooth, then through a cylindrical helical pair: a gear and a ring gear rigidly connected to the faceplate.

Machine feed boxes

The design of the feed boxes of the lateral and vertical supports is the same.

The vertical support feed box is mounted on the right end of the cross member; side caliper feed box - directly to its body.

The feed box body is a box-shaped cast iron with sufficient rigidity. All feed box shafts are mounted on rolling bearings.

The feed boxes are driven from a vertical splined shaft, which receives rotation from the output shaft of the gearbox through the mechanism for transmitting movement to the feed (see Fig. 6).

The feed boxes provide the calipers with 18 working feeds and 18 speeds of installation movements. This is achieved by switching on the appropriate combinations of electromagnetic clutches of the feed boxes (for the switching diagram of electromagnetic clutches, see Part 2 of the Operating Manual 'Electrical equipment of machine tools*).

All gears of the feed boxes are in constant engagement.

A turret head with five slots and holes for attaching a tool is mounted on a cylindrical bushing. Changing the positions of the turret is carried out remotely from a pendant control panel. By pressing the “Turret Head” button, the electric motor for turning the turret head, mounted on the upper end of the slide, is turned on. Rotation from the electric motor is transmitted through gears to the drive shaft.

The main movement (rotation of the faceplate) is transmitted from the electric motor 1 through the V-belt transmission 2 - 3 to shaft I, then through the gearbox, shaft V, bevel gears 25 - 26 and wheels 27-28 is transmitted to the faceplate. The gearbox is equipped with eight electromagnetic clutches, the switching of which allows you to provide the faceplate with 18 rotation speeds ranging from 5 to 250 rpm.

The feeds of the calipers (revolving and side) are borrowed from the faceplate through two independent feed boxes with the same kinematics. Each box is equipped with eight electromagnetic clutches, switching which makes it possible to obtain 16 feed rates for both calipers.

Horizontal feed of turret support . From shaft VIII of the faceplate through gear 28 - 27, bevel gears 26 - 25, 24 - 23, gear 29 - 30 and bevel pairs of wheels 31 and 53, the movement is transmitted to shaft XII of the feed box (shown separately at the top left). From the feed box, the shaft XX of the caliper mechanism receives rotation, and then through gears 52 and a screw pair 65, the turret caliper receives horizontal feed.

Vertical feed of the turret support . From shaft VIII of the faceplate to shaft XXI of the feed box, rotation is carried out along the same chain; Then, through bevel gears 55 - 56, a cylindrical pair of wheels 57, a conical pair 58 and a screw pair 59, the turret caliper receives the feed movement.

Horizontal feed of side support . As before, the movement goes from shaft VIII of the faceplate to shaft XII of the feed box, then through the feed box to shaft XX and then through gears 39 - 41 and screw pair 42, the side caliper receives feed.

Vertical feed of side support . From the faceplate shaft to the feed box shaft XII, the movement proceeds along the same chain, then through the feed box the shaft XXI of the caliper mechanism receives rotation and through the bevel gears 35-36 and the screw pair 43 the side caliper receives feed.

Both supports receive accelerated movement

Main drive motor control

The main drive electric motor is controlled from a pendant control panel using buttons 1Кн2 - “Start” and IKHI - “Stop”.

When you press the 1Kn2 - “Start” button, the main drive starter 1K1 is turned on. At the same time, the 1P1 relay for limiting the idle speed of the main drive electric motor is turned on, which operates with a time delay. If the faceplate is not turned on during this time, the open contact of this relay (circuit 4) will turn off the main drive starter.

The main drive electric motor is turned off by pressing the IKHI - “Stop” button.

When the faceplate is turned on, the IKHI button is blocked by the closing contact of the step finder SHIT. The main drive motor can only be turned off after the faceplate has been turned off and the step finder is in the zero position.
