Description

one

The invention relates to a machine tool and can be used for boring long sleeve-type parts.

Automatic lines for the machining of parts are known, which contain o6pa6aTBBat machines installed in the technological sequence, connected by means of a conveyor belt with lifts, and auto-operators with grippers installed at work stations I,

In well-known lines it is impossible to embed machines for deep boring of long products.

The purpose of the invention is to expand the technological capabilities of the line, i.e., the creation of an automatic line consisting of machines for deep boring.

To do this, each machine of the proposed line is equipped with a lift with prisms, spaced along the axis of the machine, installed opposite the respective conveyor lift, as well as a clamping device installed between the clamps of the operator, with the possibility of reciprocating movement along the machine axis.

FIG. 1 shows the described, line, top view in FIG. 2 is the same.

General view with digging along the machine in FIG. 3 shows section A-A in FIG. 2

An automatic line consists of installed in the technological sequence of machines 1 for deep bore, a sucker-feed conveyor 2 (Located along the front of the machines, and auto-operators 3 installed at the loading points of the machined parts in the working area of the machines.

Each machine 1 contains spindle headstock 5 mounted on the base 4 with the chuck 6 mounted on it, the headstock 7 for feeding the tool 8,

steady 9 for supporting the tool and roller steady 10 for supporting the workpiece. On the base 4 between the chuck 6 and the rest 10 is mounted a lift 11 with 12Rrisms 12 spaced along the axis of the machine 1 and mounted with the possibility of lifting and lowering from the hydraulic cylinder 13. Between the prisms 12 of the elevator 11, a self-centering clamp 14 is mounted on the bed 4; the ability to move along the axis of the machine from the hydraulic cylinder 15.

The device is made in the form of jaws 16 installed in rails

housing 17 with the possibility of counter

displacement from the hydraulic cylinder 18 connected with the jaws through the rail 19, gears 20 and 21f of the rail 22 and 23.

The conveyor 2 is equipped with a lift 24, installed opposite the lifting NIKOV 11 machines. The elevator 24 is also made in the form of two pairs of prisms 25 installed on both sides of the rod 26 transport, pa in the openings of the tray 27 with the possibility of lifting ipuskan O7 hydraulic cylinder 28.

Auto operator 3 is a carriage 29 that is moved along the guides of the crosshead 30 between the machine 1 and the conveyor 2. On the carriage 29 with the possibility of raising and lowering (from the drive, in the drawing shown "go"), a grip 31 is mounted on two tabs 32, Place the clamp in such a way that in the lowest position the clamping device 14 is between the tongs 32 Klezs 32 are clamped bf of the movable wedge 33. On one side of the grippers 32, the cam 34 is installed, interacting sadia} with the end switch 35, embedded 4 on one of the jaws 16 u TWA 14.

A rough and clean bore of cylinder liners and the subsequent rolling of the liner mirror are made on the line, and the products can be treated with both a smooth outer surface and bosses on it.

The processed product 36 enters the conveyor 2 to the working position. Since the product arrives neither the conveyor is not oriented to the coal position of the lugs, it can be based on the JioTKe conveyor or a cylindrical surface, or lugs, as a result the axis of the product does not have a stable position. The prism 25 of the elevator 24 lifts the product so that the bobotzki do not touch the tray 27 of the conveyor until the product axis is located in the plane of the axis of the centers of the machine. In this position, the product is captured by the pliers 32 of the auto operator 3 and transferred to the machine. The prisms 12 of the machine elevator 11 are at this moment in the extreme upper position, slightly above the axis of the centers of the machine, and the product is lowered by the grab 31 of the auto operator on these prisms.

In the lower position of the gripper 31, the cam 34 cooperates with the limit switch 35 mounted on the clamping device 14 and gives a command to clamp the product with the jaws 16 of the clamping device 14. and the opening of the tongs 32

grip 31. Then a command is given to raise grip 31 upwards.

In the upper position of the gripper 31, the hydraulic cylinder 15 moves the clamping device 14, which feeds the product through. prisms 12 in the cartridge 6 of the machine. After that, the jaws 16 of the clamping device 14 are unfolded and the prizes, 12 of the elevator 11 of the machine 1 are lowered. The product 36 is at this moment lowered onto the rollers of the steady 10 at one end, and the other rests on the jaws of the cartridge 6 When clamping the cartridge 6 and the steady 10, the axis of the product 36 is combined (It goes with the axis of deflection 1, after which the working

cycl machine.

After processing the xmaid on the unclamp of the Yun pdtroia b and the lifting of the yriam 12 of the elevator 11. Then the product is closed; the sponge w 16 of the clamping device

14 and prisms 12 are removed from the cartridge. The riveting 32 of the gripper 3l is lowered and in its lowest position, ksmkhan and onto the clamp of the tongs and the unclamping of the jaws 16. The auto-operator carries

the product on the conveyor 2 and lays it on the raised elevations of the elevator 24. The pliers unclench, the product is placed in the lowering of the prisms 25 on the tray 27 of the conveyor 2 and is moved by a bar

26 to the next position. Then the cycle is repeated.
