A wheel hub upper and lower bearing press assembly production line

Abstract

The invention discloses a production line for pressing the upper and lower bearings of a wheel hub, which includes a bearing pressing machine. The bearing pressing machine includes a lower bearing lifting assembly and an upper bearing pressing assembly. The base, top plate, and upper bearing press-down assembly under the station include a press plate erected above the bearing press-fitting station of the hub production line. The piston rod extension end of the lifting cylinder 2, the side of the bearing press machine is equipped with an upper and lower bearing synchronous feeding mechanism, and the side of the upper and lower bearing synchronous feeding mechanism is sequentially equipped with There are upper and lower bearing group feeding mechanism, upper bearing internal circlip pressing mechanism and lower bearing seal ring pressing mechanism. The present invention only needs one line to complete the synchronous feeding, testing, conveying, assembling and feeding of the upper and lower bearings as a group, which reduces equipment and branches and automates assembly.

Description

Technical field: [0001] The invention relates to the field of wheel hub assembly production lines, and mainly relates to a wheel hub upper and lower bearing pressing assembly production line. Background technique: [0002] The upper and lower bearings need to be assembled in the hub. In the prior art, the upper and lower bearings are mostly assembled at a single station. In order to meet the requirements of batch automatic assembly, an automatic assembly line is adopted. Therefore, the upper and lower bearings are assembled automatically. During assembly, continuous feeding is required. In the prior art, circular conveying is often used. Although the requirements for conveying and feeding are met, the bearing needs to be inspected before conveying. After the inspection, it is placed on the circular conveying line for conveying. The external detection operation requires manual loading and unloading operation, which is cumbersome, increases the labor intensity, is time-consumi...

Problems solved by technology

[0002] The upper and lower bearings need to be assembled in the hub. In the prior art, the upper and lower bearings are mostly assembled at a single station. In order to meet the requirements of batch automatic assembly, an automatic assembly line is adopted. Therefore, the upper and lower bearings are assembled automatically. During assembly, continuous feeding is required. In the prior art, circular conveying is often used. Although the requirements for conveying and feeding are met, the bearing needs to be inspected before conveying. After the inspection, it is placed on the circular conveying line for conveying. The external detection operation requires manual loading and unloading operation, which is cumbersome, increases the labor intensity, is time-consuming and laborious, and has low efficiency. Before the upper and lower bearings are press-fitted, the circlips and sealing rings between them need to be assembled in advance. Its assembly process adopts separate feeding on two lines, which requires the cooperation of two branch lines and other auxiliary mechanisms. It also needs two pick-and-place mechanisms during assembly, which virtually increases the cost of the equipment, and the assembly line Too many branches not only take up a lot of space, but also require special personnel to cooperate with the operation, and the factor of manual participation is large, which affects the assembly quality and efficiency, and cannot meet the needs of automated assembly
