The invention relates to a machine tool industry, in particular to automatic lines of metal-cutting machines,

The aim of the invention is to improve the accuracy of machining by reducing the contamination of the base surfaces of the base elements of machine tools.

FIG. 1 shows the automatic flow line, general view; FIG. 2 shows a section of an automatic production line, a conveyor bar of a transport device in an intermediate position; in FIG. 3, the same, the booms of the transport device in the upper position; Fig 4 is the same, the booms of the transport device in the lower position; in fig. 5 - view A on figs 4; in fig. 6 is a section BB, in FIG. five.

An automatic production line consists of machines 1 with base elements 2, made in the form

prisms for locating parts 3, - connected in the course of the technological process with a transport device 4 with hydraulic cylinders 5 and 6 for driving and lifting the rod 7 and two shoulders with levers 8, only 9 shoulders: pivotally connected to 10, and the other shoulders 11 are equipped rollers 12, on which are located the rod 7,

The transport device is equipped with a latch 13, locking the rod 7 in the middle position and located in a fixed bracket 14 placed on the plate 15 of the machine. The latch 15 is located under one of the levers 8 and has a drive in the form of a hydraulic cylinder 16. The latch is included in the sleeve 17 placed on the bracket 18.

The transport device has three positions: upper, middle and lower.

In the upper position, the fixing and clamping of the parts 3 at the processing positions is carried out. In the middle position, the rods 7 are moved with the parts 3 one step forward. In the lower position, the rods 7 without the parts 3 are returned to their original position.

The parts 3 on the rods 7 are placed in the clamping prisms 19. At the working positions of the machine part 3 to the clamping elements. 2 are clamped by the claws 20, between the machines there are a number of intermediate positions 21,

Liney works like this

In the initial position, the booms 7 of the transport device are in the middle position (Fig. 2). The workpiece 3 is moved to the next position by means of the hydraulic cylinder 5. Then, from the hydraulic rod 6, the stem of which moves to the left Q through T 10 and levers 8, the rods 7 with parts 3 are raised to the upper position (Fig. 3), i.e. in the fixture of the machine 1, not income to the base surfaces of the prisms 2 1-2 mmo

The machined parts 3 are fixed in prisms 2 by pressing with sticks 20. End of pressing to prisms gives a command to operate power heads (not shown) and simultaneously to lower the rods 7. During this movement, the machined parts 3 located at intermediate positions 21 remain in the middle position on the fixed prisms 19, and the rods 7 lower further downwards.

Further, from the hydraulic cylinder 5 of the drive for the longitudinal movement of the rod 7, they move one step in the opposite direction (without parts),

Then, from the hydraulic cylinder 6, through the pulleys 10 and the arms 8 of the rod-7, rise to the upper position behind the treated part 3, which is unlocked and pressed by the clamps 20, then the rod 7 with the parts 3 lowers B the middle position until the lever 8 stops in the locking latch 13 (Fig. 4), which moves from the hydraulic cylinder 16.

Further, the rods 7 with the parts 3 located at the intermediate 21 and the working positions of the machine 1 are moved to step t, and the cycle is repeated.
