A plurality of anchor clamps have evenly been arranged on the workbench surface of rotary table formula multistation modular machine tool, and part to be processed just is clamped on these anchor clamps successively.The type equipment is mainly used in the manufacturing in enormous quantities of identical parts, and requiring has very high production efficiency, so a general configuration hydraulic pressure quick-speed jigs comes the clamping part to be processed.Part to be processed generally all is the type parts such as irregular valve body that shape is comparatively complicated, a plurality of clamping faces are arranged.Most of building-block machine manufacturing firm all continues to use old process, all adopts line cutting to process the clamping face and the profile of jaw, generally all makes the structure of rectangle.Do like this that manufacturing process is comparatively simple, manufacturing expense is lower, but owing to be difficult to adopt higher fine finishining means, so the accuracy of manufacture is not high, particularly a building-block machine uses 6 ~ 12 sleeve clamps, the uniformity difference of a plurality of anchor clamps is bigger, the repetitive positioning accuracy of anchor clamps is just poor, generally only is used for clamping die casting class blank part.
Along with development and national economy, use producer also more and more higher to the requirement on machining accuracy of equipment, their proposition equipment is used for the secondary operations of part, promptly is used for the clamping machined surface.In order to reach shaped position precision higher between clamping face and the machined surface, must abandon traditional wire cutting technology method, employing can be made high-precision clamp part by the process that Precision Machining improves the clamping precision.
The utility model content
Goal of the invention: in order to overcome the deficiencies in the prior art, the utility model provides a kind of cylindrical self-centering clamping device, can adopt the method for grinding to obtain very high anchor clamps precision, help guaranteeing a plurality of grip size uniformity, and can obtain high part processing shaped position precision.
Technical scheme: for achieving the above object, a kind of cylindrical self-centering clamping device of the present utility model, comprise clamp body and the pressing plate that is positioned at the clamp body side, described pressing plate comprises top board and lower platen, be provided with slide block between top board and the lower platen, slide block comprises left slider and right slide block, be respectively equipped with semicylindrical opening on left side fixture block and the right fixture block, two semicylindrical opening butt joints form complete cylindrical hole, in the semicylindrical opening of left side fixture block left jaw is housed, in the semicylindrical opening of right fixture block right jaw is housed, left jaw and right jaw are half round post.
As preferably, described left fixture block and right fixture block top are equipped with positioning key, and left jaw and right jaw top all have groove, and positioning key is connected in the groove.
Described clamp body inside is provided with and drives the hydraulic pressure driving lever that slide block moves.
Beneficial effect: in the cylindrical self-centering clamping device of the present utility model, because fixture block is made cylindrical with the centering part that cooperates of jaw, can adopt the method for fine finishing of grinding to make high-precision clamp part, so can obtain high piece-holder precision, help guaranteeing a plurality of grip size uniformity of installing on the rotary table, and have the advantage that can compensate automatically after easy to assembly, the wearing and tearing, successfully solved the manufacturing difficult problem of building-block machine precise clamp.
