Ball separating and riveting method for assembling small-sized deep groove ball bearing

Abstract

The present invention is ball separating and riveting process of assembling small deep flute ball bearing. The assembling process includes two parts of separating balls and riveting arranged linearly, and the workpiece shifting equipment for shifting the workpiece from the ball separating part to the riveting part has workpiece shifting mechanism including ball separating shift tray and riveting shift tray. The present invention adopts the advanced technologies of photoeleectronic sensing, on-line detection, pneumatic pressurizing, etc. and has convenient linearly arranged work sites. The present invention has high production efficiency, high assembling quality and other advantages, and the assembled bearing has less vibration noise and high flexibility.

Description

1. Technical field: [0001] The invention relates to a method for assembling small bearings, and in particular discloses a split ball riveting method for assembling small deep groove ball bearings. 2. Background technology: [0002] Ball riveting of bearings is a relatively heavy workload in bearing assembly. In the past, this work in the bearing industry was mainly manual, and a large number of assembly workers were concentrated, which can be called "human sea war". The use of automatic ball riveting equipment is one of the most important signs for bearing companies to move towards modern production. [0003] At present, the ball riveting methods still commonly used in the bearing industry are mainly: [0004] 1. Traditional manual ball distribution and riveting: [0005] This is a relatively primitive and simple traditional method in the bearing manufacturing industry and is widely used. The process is: [0006] (1) Put the half cage ball pocket upwards on the special ...

AI Technical Summary

Problems solved by technology

[0019] (2) Separation of ball distribution and riveting: that is, ball distribution and riveting are carried out on two devices. Although this method simplifies each device, the connection between them is more complicated, and it takes up The area is also large

[0021] 1. Poor assembly quality: when the ball is divided, the surface of the steel ball and the surface of the inner and outer ring grooves are easily damaged; when riveting, the cage is easily deformed, and even the ball pocket is in contact with the steel ball, which affects the flexibility and vibration of the bearing Noise; the cage ball pocket is easy to deform, and the bearing flexibility is poor; human factors are greatly affected, such as frequent lack of balls, nails, etc.;

[0022] 2. Large area;

[0023] 3. Many production workers;

[0024] 4. Low production efficiency;

[0025] 5. There are many potential safety hazards, especially when riveting by hand
