Abstract
The utility model discloses a double-claw clamping disk which comprises a clamping disk body and two clamping claws which are the same in structure. The clamping disk body is further provided with two ejector rods. Threads are arranged on an outer ring of each ejector rod. The ejector rods are screwed with the clamping disk body through screw holes in the clamping disk body. Clamping parts of the clamping claws are provided with fishtail-shaped grooves. The fishtail-shaped grooves form an included angle alpha which is 120 degrees. The fishtail-shaped grooves and the ejector rods are further provided with copper clamping mark preventing gaskets. The double-claw clamping disk can prevent a workpiece from loosening and clamp marks from occurring, and improve precision at machining time.
Description
Technical field
The utility model relates to a kind of lathe parts, the chuck that especially a kind of lathe is used.
Background technology
The clamping part of union chuck claw is the plane in the prior art, and when the workpiece of processing belt curved surface, chuck probably clamps not strongly, the accuracy of influence processing, and in clamping process, easily stay catcher mark at workpiece, influence the accuracy of workpiece.
The utility model content
The utility model purpose is to overcome above-mentioned the deficiencies in the prior art, provides a kind of workpiece that can effectively prevent loosening, improves the chuck of machining accuracy.
The technical solution of the utility model is: a kind of union chuck, the claw that comprises chuck body and two same structures, also be provided with two push rods on the described chuck body, outer ring, push rod bottom is provided with screw thread, push rod is screwed by screw and the chuck body that is arranged on the chuck body, the clamping part of described claw has the fish tail shape groove, and the angle α that the fish tail shape groove forms is 120 °, also is provided with copper anti-catcher mark pad on described fish tail shape groove and the push rod.
The beneficial effects of the utility model are: the fish tail shape groove has guaranteed that push rod can screw on the chuck body as required, holds out against workpiece to the chucking power of band curve surface work pieces, guarantees that workpiece can not become flexible; The material of copper anti-catcher mark pad can effectively prevent from staying cut at workpiece in clamping process owing to relatively soft, has improved the chuck machining accuracy.
