Embodiment Construction

[0016] Specific embodiments of the present invention are described with reference to the accompanying drawings.

[0017] as attached figure 1 It is the finished outer ring 1 of the ultra-thin wall bearing, with figure 2 It is the finished inner ring of ultra-thin-walled bearing 2.

[0018] to be processed as attached figure 1 , 2 For the finished outer ring 1 and finished inner ring 2, the processing method adopted by the present invention is as follows: first, the forging blank is selected according to the size of the bearing ring to be processed, and the forging blank is turned into a car with a reinforcing ring 5 inside. Second as attached image 3 Outer ring turning workpiece shown and attached Figure 4 The shown inner ring turning workpiece; then after the turning workpiece with the reinforcement ring 5 is heat-treated, the groove is directly processed by grinding instead of turning into the attached Figure 5 Outer race shown before cutting off and as attached ...

Abstract

The invention discloses a processing method for a ball bearing with an ultra-thin wall and uniform section. The processing method comprises the following steps of: a, selecting a forge piece blank according to the size of a bearing ring to be processed, and lathing the forge piece blank into an one-lathing-two lathe workpiece with a reinforcing ring inside; b, after performing heat treatment to the lathe workpiece with the reinforcing ring, performing grinding process to the lathe workpiece, wherein channel processing is finished directly by grinding instead of lathing; and c, after finishing grinding process, breaking a product except a cut surface into two workpieces at the position of the outer diameter through grinding by a thin grinding wheel, removing the reinforcing ring and polishing the cut surface. According to the invention, the rigidity of the bearing ring is greatly enhanced due to the existence of the reinforcing ring when the bearing ring is processed, thereby enhancing the feasibility of lathing and the processing precision; meanwhile, the heat treatment deformation is greatly reduced, and the grinding can be normally performed; and moreover, one reinforcing ring can be used for lathing two bearing rings, thereby being economical.

Description

technical field [0001] The invention belongs to the bearing processing technology, and mainly relates to a processing method of an ultra-thin-wall equal-section ball bearing. Background technique [0002] Ultra-thin-wall equal-section ball bearings are widely used in robotics, aerospace, medical equipment, astronomical instruments, Satellite communication and other fields, but this kind of structure has very thin wall thickness, narrow width, very weak rigidity, and changes at a touch. No matter from lathe processing, heat treatment or grinding processing, there are great processing difficulties. Contents of the invention [0003] The invention provides a processing method for processing ultra-thin-wall equal-section ball bearings, which solves the problem of high processing difficulty in turning, grinding and heat treatment processes. [0004] The purpose of the present invention can be achieved by adopting the following technical solutions: the processing method of ...
