SU36935A1 - Portable parallel vice - Google Patents

Description

When repairing railway lines away from specially equipped machine shops, there is a special need for a reliably installed bench clamp; The absence of a vice forces the part to be repaired to be delivered to the workshop or somehow adapted to the conditions, which inevitably affects the quality of work.

In order to eliminate the disadvantage, portable parallel vices are offered, in which there is an intermediate movable clip, equipped with a sponge on one side, which serves together with the jaw box protrusion for fixing the entire device on the rail, and with a sponge, designed for fastening the workpiece.

The drawing shows a General view of the proposed vice in a perspective view.

In the vise box 1, there are, on the longitudinal sides of the inside, guides carrying a freely movable sponge 2 connected by a screw 3 located in a nut located in the front transverse side of the box and provided with a handle; next to the sponge 2 on the same guide box I installed

(610). -.

intermediate movable clamp 4. This clamp, with its front part together with a 2-vice sponge, serves to secure the workpiece. To strengthen the vice on the rail, the box 1 is provided with a protrusion 5, and a sliding clip 4 with its lower side with a sponge 6.

During repair work on railway tracks, the vise is fixed on the rail simultaneously with the clamping of the workpiece; by screwing in the screw 3, the sponge 2 is moved, which presses the part against npoMt.k-. on that clip 4. The latter in turn moves and presses against the rail head abutting the other side against the protrusion 5 of the box 1.

The proposed vice allows, to a certain extent, convenience for those working on the line, and, moreover, is easily removed from the rail when the train appears, since they can be attached to the rail when the parts are fixed in them, i.e. them any work. When parts are removed from a vice, the vice is easily removed from the rail. The same vice can also be attached to the table, workbench, etc., in a vertical position, for example, for clamping pipes and other long parts.
