The utility model is finished by following technical scheme.The utility model is a kind of quick-gripping device, comprises housing unit, runner assembly and clamp assembly;

Housing unit comprises housing, voussoir and upper and lower push pedal, has straight trough on the housing, and voussoir and upper and lower push pedal fuse and be positioned at outside the housing, have on the voussoir with housing on the skewed slot arranged of straight trough bevel, the other end of following push pedal links to each other with cylinder;

Runner assembly comprises hollow shaft, clutch shaft bearing, second bearing and collet, the hollow shaft that the outside is with clutch shaft bearing, second bearing is contained in the interior end of housing, one end of hollow shaft and collet is fixed together with second screw, has the plurality of elastic sheet on the collet, have the conical surface of compressing on the outer surface of each flexure strip, the other end of collet is positioned at the other end of housing;

Clamp assembly comprises throw-out collar, the 3rd bearing, clamping ring and shifting block, throw-out collar is connected as a body through the 3rd bearing and clamping ring, and is sleeved on outside the collet, and shifting block one end is fixed on the throw-out collar, the straight trough of the other end on housing projects outward from the housing, and extend in the skewed slot of voussoir; Clamp in the annular distance and have compacting ring.

In the utility model, throw-out collar, the 3rd bearing, clamping ring are moved vertically, compacting ring is compressed or unclamp the conical surface that compresses of each flexure strip, with the clamping of control collet or loosen by moving axially of shifting block.

During work, up when cylinder, it is up to promote upper and lower push pedal and voussoir, through the skewed slot of voussoir shifting block is moved to right, and makes throw-out collar promote clamping ring and moves to right, and each flexure strip is compressed, with piece-holder.Otherwise, then each flexure strip is loosened, workpiece is loosened.

In sum, the utility model is simple and compact for structure, can be fast, clamping round piece stably.Be applicable to quick-clamping workpiece or bar.

The specific embodiment

As Fig. 1,2,4 is the structure chart of the utility model quick-gripping device, comprises housing unit, runner assembly and clamp assembly;

Housing unit comprises housing 6, voussoir 15 and upper and

lower push pedal

16,17, has straight trough 6-1 on the housing 6, voussoir 15 fuses with upper and

lower push pedal

16,17 through the 4th screw 19, and be positioned at outside the housing 6, have on the voussoir 15 with housing 6 on the skewed slot 15-1 (Fig. 3) that arranges of straight trough 6-1 bevel, the other end of following push pedal 17 links to each other with cylinder 18;
