Description

(54) SELF-CENTERING VISS

one

The invention relates to clamping devices for metal cutting machines and can be used for self-drilling and fastening machining for parts.

A known mechanism for clamping a product is LII, comprising a housing mounted on its starting slider with sponges and a power actuator with an untm synchronous slider.

The disadvantage of this mechanism is the presence of one guide for installing and moving on it: pops: new with jaws, which increases the dragging distance on the poles and the length of the vice itself.

The closest in technical essence to the proposed invention will be inserted self-centering vise, containing a casing, a guide, on which sliders with sponges and a power actuator of the synchronous period creep are mounted.

A disadvantage of the known device is also the increased length of movement of the sliders on one guideline, which increases the distance from the front overhangs of the vice to the axis of the clamped part, i.e. the length of the grip.

The purpose of the invention is to reduce the length of the vice without reducing the movement of the sliders.

The chain is achieved by the fact that the self-center

The 10 gripping vices of the 1-strut direction, which is made of two paraplels, one another, each with a slider with a t-slab.

FIG. 1 depicts an amiable vent vice, general view; in fig. 2 is a view A of FIG. 1, in FIG. 3 - view B on figd.

Claims (2)

The self-venting vise contains a body 1, a guide of two parallel parts 2 and 3, on which the sliders 4 and 5 with jaws 6 and 7 are mounted, the slide 4 is rigidly connected to the rod 8, and the slide 5 is connected to the cylinder 9 power cable 1O, sliders 4 and 5 are interconnected kinematically by means of a gear wheel 11 having two gears (not shown) for synchronous nepavrraneHBH sliders 4 and 5. The gear wheel 11 is mounted on axis 12, fixed in housing 1 , and engages simultaneously with the rack 13, rigidly mounted on the slider 4, "with a tooth Second pinion 14 rigidly fixed on the slide 5, screw 15 serves to regu lirovki stroke vise. Kro1Sh1teyn 16 is designed to support parts during loading - unloading. Self-centering vices operate as follows from the seedlings. When the workpiece 17 is clamped, the rod 8 moves to the left and pushes the slider 4 together with the sponge 6, and the cylinder 9 simultaneously moves it together with the slider. 5 and a sponge 7. When the workpiece is uncoupled, the pressure 17 is supplied to the other cavity of the power drive, and the slide blocks 4 and 5 move in opposite directions. In this case, the wheel 11, being adjusted on the axis 12, determines the ratio between the lengths of the course of the sliders 4 and 5. Since the self-centering vise is made with two: separate for each slide, parallel guides arranged in parallel, the length of the vise is reduced, the distance from the axis of the clamped part to the front protruding parts of the vise is reduced. Claims of the invention A self-centering vice comprising a body mounted on its guide jaws with jaws and a synchronous movement force actuator, characterized in that, in order to reduce the length of the jaws without reducing the movement of the sliders, the guide is made of two parallel to one another parts which is located the slide with a sponge.
