Description

The invention relates to a machine tool industry, in particular to the double-sided machining of parts.

The aim of the invention is to reduce the time of commissioning and installation work by simplifying the exhibition fixtures for parts of various lengths,. ..

Fig I depicts a machine, a general; view; in fig, 2 - m, plan,

 contains stanza | 1u 1, on which power tables 2 are installed with instrumental, heads 3 and fixture 4 for securing parts, made of two identical parts 5 and 6, on one of which (, 5) the bar is fixed with divisions 7, and on the other (.6) there is a limit switch 8. On the bar 7 the visor-stop 9 is mounted for moving and contacting with the limit switch 8. The power tables 2 and parts 5 and 6 of the device are mounted to move along the frame 1 from the drive made in the form of hydraulic cylinders 10. Stock 11 hydrocyles wood connected with the portions 5 and 6 of tool.

The machine works as follows.

When readjusting the fixture - 5 to install parts of a different length

its parts 5 and 6 are uncoupled on the bed 1, the visor-stop 9 is mounted on the bar 7 to the required size. When commanded by the machine control panel 10, the hydraulic cylinders 10 move parts 5 and 6 of the fixture on the base 1 until the end switch 8 triggers when interacting with viewfinder 9, Parts 5 and 6

 5, the fixtures are stopped in the required position, they are fixed on the bed 1. Then, the workpiece is mounted on the fixture, clamped and begins

20 machining operations

The adjustment and adjustment movements of the fixture are longer than the stroke of the hydraulic cylinder 10 by 25 repeated sequential movements of the power tables 2 relative to the parts 5 and 6 of the fixture. or vice versa.
