Roller type bearing spinning closing-in device and using method thereof

Abstract

The invention relates to a roller type bearing spinning closing-in device. The device comprises a tool handle, a spinning head, embedded bolts, a bolt rod, a round frame base and a guide shaft. A plurality of bolt holes are formed in the spinning head, the bolt holes run through the spinning head, the bolt holes are formed at equal angles with the central axis of the spinning head as the axis, theincluded angle between each bolt hole and the horizontal plane is 25 degrees, the tool handle is perpendicular to the spinning head and located in the middle of the spinning head, the guide shaft iscylindrical, the outer circle diameter of the guide shaft is matched with the size of an inner hole of a to-be-machined bearing, and the length of the guide shaft is matched with the thickness of theto-be-machined bearing. The guide shaft is cylindrical, the outer circle diameter of the guide shaft is matched with the size of the inner hole of the to-be-machined bearing, and the length of the guide shaft is matched with the thickness of the to-be-machined bearing. The device is simple in structure, self-manufacturing and reconstruction can be realized, production is simple and convenient, themachining mode is simple, abrasion of the closing-in device is reduced, and the service life of the closing-in device is effectively prolonged.

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...

Problems solved by technology

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.
