Problems solved by technology

[0002] In the current shaft processing process, the general process is double-head turning, heat treatment, grinding, straightening, rough grinding, fine turning inner hole, finishing length, fine grinding, cleaning and inspection. Before finishing the inner hole of the shaft, the shaft needs to be roughly ground, in order to facilitate the clamping of the workpiece during finishing machining, but when finishing the inner hole, the jaws are generally used to clamp the workpiece, which is prone to wear on the surface of the workpiece and the stepped surface. During the clamping process, it is necessary to use a positioning device for centering positioning, which is complicated to operate and low in production efficiency

Abstract

The invention discloses a shaft finish machining clamp. The shaft finish machining clamp comprises a base, a shell, a connecting sleeve, an expansion sleeve and a supporting cover. A base mounting cavity, a connecting sleeve mounting cavity and an expansion sleeve mounting cavity are sequentially formed in one end of the shell, the expansion sleeve is contained in the expansion sleeve mounting cavity, and the connecting sleeve is mounted in the connecting sleeve mounting cavity; one end of the expansion sleeve is connected with the connecting sleeve in a matched mode, the other end of the expansion sleeve is arranged on a port of the other end of the shell, and the supporting cover is fixed to the port of the other end of the shell. The base is fixed in the base mounting cavity, and one end of the base is connected with the connecting sleeve. According to the shaft finish machining clamp, a workpiece is fixed through the expansion sleeve, the movable center is arranged in the shaft finish machining clamp for centering, the clamp conducts positioning through the maximum outer circle of the workpiece, clamping operation is easy and convenient, the workpiece cannot be abraded in the clamping process, centering positioning of the workpiece is completed in the clamping process, and production efficiency is improved.

Description

technical field [0001] The invention mainly relates to the field of mechanical processing equipment, in particular to a shaft finishing fixture and a shaft processing machine tool. Background technique [0002] In the current shaft processing process, the general process is double-head turning, heat treatment, grinding, straightening, rough grinding, fine turning inner hole, finishing length, fine grinding, cleaning and inspection. Before finishing the inner hole of the shaft, the shaft needs to be roughly ground, in order to facilitate the clamping of the workpiece during finishing machining, but when finishing the inner hole, the jaws are generally used to clamp the workpiece, which is prone to wear on the surface of the workpiece and the stepped surface. During the clamping process, it is necessary to use a positioning device for centering positioning, which makes the operation complicated and the production efficiency low.
