Holder turning fixture

Abstract

The invention relates to a holder turning fixture. The holder turning fixture is characterized in that the holder turning fixture is composed of three arc clamping jaws, the arc clamping jaws are welded to three sliding blocks with huge belt sliding teeth, the sliding blocks with the huge belt sliding teeth are connected to a chuck of a machine tool and move along with the chuck, and the action of clamping workpieces is done. In a bearing holder turning procedure, the inner and outer diameter clamping point or line contact for clamping a holder is designed to face contact, after the contact face is increased, the form and location tolerance quality of the holder is improved, the quality problems such as triangles, ellipses and ridge roundness can be thoroughly solved, the turning quality of the holder is guaranteed, and therefore the boring quality of the next procedure is guaranteed. The quality problem that sleeving rotation of the holder is poor for a long time is solved.

Description

technical field [0001] The invention relates to a clamp for a turning tool of a cage. Background technique [0002] In the bearing assembly, the four major parts of the bearing, the inner ring, outer ring, rolling element, and cage, often have quality problems that the rotation is not flexible after assembly. A large proportion is caused by the triangular, elliptical, and eccentric quality problems of the bearing cage. The reason is that most of them are caused by improper clamping during processing. Especially the light series bearing cage, due to the thin wall, the normal three-jaw chuck jaws are used to clamp the workpiece in the turning process. When this three-jaw fixture clamps the cage, the clamping track is a point or a line , On the clamped workpiece, these points or lines cause the product to form clamping deformation, which does not meet the product standard requirements. As product quality requirements become more and more stringent, this contradiction is also...

AI Technical Summary

Problems solved by technology

Especially the light series bearing cage, due to the thin wall, the normal three-jaw chuck jaws are used to clamp the workpiece in the turning process. When this three-jaw fixture clamps the cage, the clamping track is a point or a line , on the clamped workpiece, these points or lines cause the product to form a clamping deformation, which does not meet the product standard requirements

As the product quality requirements become more and more stringent, this contradiction is also increasing. This is also a difficult problem in the industry, and it has not been well resolved.
