Problems solved by technology

[0002] At present, in the processing of the FT1030 rear reducer housing, the bolt mounting holes of the large plane are processed by ordinary drilling machines, and each bolt mounting hole is drilled out one by one, and the position measurement is difficult to guarantee, which affects the subsequent process. Bolt installation, the front and rear bearing holes of the driving gear are processed by CNC lathe, the coaxiality of the two bearing holes is difficult to guarantee, the coaxiality and roundness of the two bearing holes of the differential are poor, and the design requirements of the drawings cannot be met. Poor dimensional consistency, cumbersome operation, low production efficiency and high cost

The technology is characterized by comprising the steps of positioning and clamping, turning of a large outer circle andan end face, drilling and spot facing, rough and fine boring of main tooth front and rear bearing holes, mounting of a bearing cover, rough and fine boring of a differential bearing hole, milling of athreaded hole, testing of leakage and cleaning. The product meets the design requirements, the size is stable and reliable, the consistency is good, the operation is simple and convenient, the production efficiency is high, the cost is low, and the popularization and reference values are achieved.

Description

technical field [0001] The invention relates to a processing technology of an automobile part, in particular to a processing technology of an FT1030 rear reducer shell. Background technique [0002] At present, in the processing of the FT1030 rear reducer housing, the bolt mounting holes of the large plane are processed by ordinary drilling machines, and each bolt mounting hole is drilled out one by one, and the position measurement is difficult to guarantee, which affects the subsequent process. Bolt installation, the front and rear bearing holes of the driving gear are processed by CNC lathe, the coaxiality of the two bearing holes is difficult to guarantee, the coaxiality and roundness of the two bearing holes of the differential are poor, and the design requirements of the drawings cannot be met. Poor dimensional consistency, cumbersome operation, low production efficiency and high cost. Contents of the invention [0003] The object of the present invention is to over...
