Roller type bearing spinning mouth closing device and using method thereof

Abstract

The invention relates to a roller-type bearing spinning mouthpiece, which includes a tool handle, a spinning head, an embedded bolt, a bolt rod, a circular frame seat, and a guide shaft. The spinning head is provided with several bolt holes, and the bolt The holes run through the spinning head, and the bolt holes are equiangularly distributed with the central axis of the spinning head as the axis. The bolt holes are at an angle of 25° to the horizontal plane, and the tool handle is perpendicular to the spinning head and located in the middle of the spinning head. , the guide shaft is a cylinder, the outer diameter of the guide shaft matches the size of the inner hole of the bearing to be processed, and the length of the guide shaft matches the thickness of the bearing to be processed. The guide shaft is a cylinder, the outer diameter of the guide shaft matches the size of the inner hole of the bearing to be processed, and the length of the guide shaft matches the thickness of the bearing to be processed. The invention has a simple structure, can be self-made and modified, is easy to produce, has a simple processing method, reduces wear of the mouthpiece, and effectively improves the service life of the mouthpiece.

Description

technical field [0001] The invention relates to the technical field of assembly bearing closures of aviation small components, in particular to a roller-type bearing spinning closure and a method for using the same. Background technique [0002] At present, there are a lot of bearings installed in small components in the aviation manufacturing industry, and the processing volume of bearing closures is very large, and the existing bearing closures are mostly manual closures or mechanical double vertical wheel closures. Manual closing requires a lot of work for workers, high technical requirements, difficult to guarantee processing accuracy, and high failure rate. However, the closing efficiency of the double vertical roulette is poor, it is easy to get stuck during operation, the precision is unstable, and it is easy to cause scratches around the V groove. [0003] As the number of bearing parts increases and the types of bearings increase, the manual method and rolling meth...

Manual closing requires a lot of work for workers, high technical requirements, difficult to guarantee processing accuracy, and high failure rate

However, the closing efficiency of the double vertical roulette is poor, it is easy to get stuck during operation, the accuracy is unstable, and it is easy to cause scratches around the V-groove

[0003] As the number of bearing parts increases and the types of bearings increase, the manual method and rolling method greatly increase the processing time, reduce the manufacturing efficiency, and the surface quality is not easy to guarantee

Manual processing also has the disadvantages of uneven pressure and poor uniformity, while double vertical roulette rolling wears quickly on the mouthpiece, poor quality assurance, and easy to cause scratches, resulting in the disadvantages of too much and too little in actual production applications.
