Problems solved by technology

[0002] For steel bearing sleeves with special structure, due to the influence of gravity on the bearing sleeve, the bearing sleeve cannot be fixed on the assembly tool
The traditional assembly method will not be able to realize and solve the problem of the assembly rotation relationship between the bearing sleeve and the seat body
In addition, for the seat body with a large interference of the bearing sleeve, press-fitting under normal conditions will cause the interference required by the soft seat body to be cut by the hard material, thus losing the pressing force
Through the traditional hard pressing method, on the one hand, the seat body is greatly damaged. On the other hand, there are also a series of problems such as large pressing force due to the large interference of the bearing sleeve, the bearing sleeve cannot be assembled in the end, and the assembly speed is slow. question

Abstract

The invention relates to a magnet assembly tool and an assembly process for application of matching the magnet assembly tool with liquid nitrogen cold assembly technology. The magnet assembly tool comprises a bottom plate and a pressing rod located above the bottom plate, a first positioning pin is arranged in the middle of the bottom plate, and two second positioning pins are arranged on the sideportion of the bottom plate. The pressing rod comprises a rod part and a positioning disc on the rod part, a positioning block is arranged in the middle of the positioning disc, and two third positioning pins are arranged on the side portion of the positioning disc. A magnet is mounted at the upper end of the pressing rod. The assembly process that the magnet assembly tool and the liquid nitrogencold assembly technology are applied in a matched mode enables the manufacturing cost to be low and operation to be easy and convenient, and the application that the tool and the liquid nitrogen coldassembly technology are applied in a matched mode enables part assembly efficiency to be high and the size to be stable.

Description

technical field [0001] The invention relates to a magnet assembling tool and an assembling process used in conjunction with liquid nitrogen cold assembling technology, belonging to the technical field of tooling equipment. Background technique [0002] For steel bearing sleeves with special structure, due to the influence of gravity on the bearing sleeve, the bearing sleeve cannot be fixed on the assembly tool. The traditional assembly method will not be able to realize and solve the problem of the assembly rotation relationship between the bearing sleeve and the seat body. In addition, for the seat with a large interference of the bearing sleeve, press-fitting under normal conditions will cause the interference required by the soft seat to be cut by the hard material, thus losing the pressing force. Through the traditional hard pressing method, on the one hand, the seat body is greatly damaged. On the other hand, there are also a series of problems such as large pressing f...
