Method and device for assembling multiple shaft parts with angle requirements in deep hole

Abstract

The invention belongs to the field of machine assembling and relates to a method and a device for assembling multiple shaft parts with angle requirements in a deep hole. The method comprises the following steps of 1) determining the position a pin hole in a shell assembly when the last shaft part in the multiple shaft parts is assembled in the deep hole of the shell assembly; 2) assembling the first shaft part in the multiple shaft parts in the deep hole of the shell assembly based on the position of the pin hole in the shell assembly; 3) assembling the second shaft part in the multiple shaftparts in the deep hole of the shell assembly based on the position of the pin hole in the shell assembly, wherein the end surface of the second shaft part is in contact with the end surface of the first shaft part; and 4) repeating the step 3) till the multiple shaft parts are assembled in the deep hole of the shell assembly. The invention provides the method and the device for assembling multipleshaft parts with angle requirements in the deep hole, wherein the method and the device are accurate to position, convenient to assemble and stable and reliable in operating process and can improve the production efficiency.

Description

technical field [0001] The invention belongs to the field of mechanical assembly, and relates to an assembly method of shaft parts, in particular to a method and a device for assembling a plurality of shaft parts with angular requirements in a deep hole. Background technique [0002] Shaft parts are one of the common parts in all kinds of mechanical products. Due to functional requirements, such parts usually have clearance fit with the housing components, and the different cavities in the housing are separated by sealing rings. The structure of a part of an aeroengine is as follows: figure 1 As shown, the component includes a housing assembly 4 , and a first shaft 1 , a second shaft 2 and a third shaft 3 assembled inside the housing assembly 4 from inside to outside and along the axial direction of the housing assembly 4 . Among them, sealing rings 6, 7 and 8 need to be assembled between the first shaft 1, the second shaft 2 and the third shaft 3 and the housing assembly 4...

AI Technical Summary

Problems solved by technology

If the pin 5 is used to assemble the first shaft 1, the second shaft 2 and the third shaft 3 sequentially outside the housing and then put them into the housing assembly 4, there will be problems due to the narrow space and the lack of visual inspection. Failure to fit or damage seals installed on the shaft

That is to say, the method of installing the three shaft parts as a whole is extremely difficult to operate, and it takes a lot of time to disassemble if the assembly is not in place, and if the seal ring is damaged and falls into the housing, it is not easy to take it out, and it is easy to damage the housing. bring secondary pollution
