Abstract

Usage: can be applied in the structures of auxiliary devices for supporting parts processed on aggregate metal-cutting machines and automatic lines. The invention: the device comprises a housing with a spring-loaded plunger with a wedge surface of the support element. The plunger can be moved by a spring until it touches the support member with the part. The plunger and the support element are held in this position due to the chamber 7 connected by a channel to the hydraulic system. 3 sludge.

Description

The invention relates to a machine tool industry, in particular, to designs of auxiliary devices for supporting a part machined on aggregate metal-cutting machines and automatic lines.

The purpose of the invention is to increase reliability, simplify the design and reduce size.

FIG. 1 shows a longitudinal section of the support; in fig. 2 is a section A-A in FIG. one; in fig. 3 is a section BB in FIG. one.

The support includes a housing 1 with a central through hole B and covers 2, 3 covering it on both sides of the housing 1. A plunger 4 is placed in the hole B to form two cavities. A plunger 4 is made of a wedge surface - a groove in which the supporting element 5 is placed with a wedge surface - a projection D in the form of a dovetail. In addition, on the side surface of the plunger 4 there is a flat face 6, which, together with the wall of the opening B, forms a chamber 7 to which

A pressure channel 8 is provided for locking the plunger 4 with the support element 5 in a certain position. In the left cavity, a spring 9 is installed, intended for supplying the support element 5 to the part 10.

The right cavity of the housing 1 is connected through a channel 11, made in the cover 3, with a pressure system, under the action of which the plunger 4 returns to its original position with the removal of the support element 5 from the part 10.

Driven support works as follows.

In the initial position, the plunger 4 is in the extreme left position under the action of oil flowing through the channel 11. At the same time, the spring 9 is compressed, the supporting element 5 is in the position retracted from the part 10.

To supply the support member 5 to the component 10, the pressure through the channel 11 is released. Here, the plunger 4 is moved to the right by the action of the spring 9, until

until the support element 5 contacts the part 10. Thereafter, pressure is applied through the channel 8 to the chamber 5 in order to lock the plunger 4 and the support element 5 in this position.
