a fixture

Abstract

The invention belongs to the technical field of fixtures, and in particular relates to a fixture, which includes an intermediate fixture and an execution fixture, wherein the execution fixture is connected with the inherent fixture on the machine tool through the middle fixture; the fixture designed by the invention can be applied to a cylinder with a thinner thickness In the process of use, the inner wall and the outer wall of the workpiece are fixed at the same time by three inner splints and outer splints, which can improve the fastening effect. Under the same fastening effect, the clamping force of the fixture on the workpiece can be The relative reduction prevents the occurrence of pinching the workpiece to a certain extent. In the present invention, three fastening mechanisms are designed. After the positions of the three mounting shells are fixed relative to the housing of the execution fixture, the three mounting shells of the three fastening mechanisms play a fixed and restrictive role, ensuring that the fixture clamps the workpiece. stability.

Problems solved by technology

[0004] For workpieces with a cylindrical structure, in machining, the traditional triangular chuck is generally used to clamp the inner or outer circle of the workpiece; but for thinner workpieces, no matter whether it is through the outer Whether it is circular clamping or inner circle clamping, if the clamping force is not properly controlled, the workpiece may be clamped; it will affect the appearance and the later work, but in order to prevent the clamping of the workpiece, if the clamping force is reduced, the high-speed movement of the workpiece During the process, there will be a phenomenon of falling off, accidentally injuring the machine or the staff

[0005] The existing technology will use a layer of gaskets with equal thickness on the inner or outer circle of the workpiece, but this will easily cause the workpiece to slip due to friction on the one hand, and on the other hand, if the gasket is worn, the axis of the workpiece will be out of alignment. The misalignment of the axis of the fixture affects the machining accuracy
