Abstract

The invention provides a stamping and welding axle housing machining technology, and relates to the technical field of heavy-truck axle housing machining technologies. The stamping and welding axle housing machining technology includes the steps of 1, putting a raw axle housing; 2, levelling an end face chamfer; 3, conducting coarse-fine treatment on a vehicle axle housing spindle head and flangeouter-circle end faces at all levels, and cutting threads; 4, conducting coarse-fine milling on end faces, conducting coarse-fine boring on inner holes, drilling holes in a disc face, tapping the discface, and conducting coarse-fine boring on through-shaft inner holes and end faces at all levels; 5, polishing an outer circle; 6, milling keyways; 7, conducting cleaning; 8, carrying out final inspection; 9, putting a product in storage. The step 4 is a machining technology based on a horizontal machining center. By the stamping and welding axle housing machining technology, the implantation andapplication of an axle housing machining integrated technology in homemade complete machining equipment are achieved for the first time, optimal distribution of machining tasks in a flexible production line is achieved, the machining efficiency of a cluster machining system is improved, a heavy-truck axle housing flexible machining technology is improved, and the application and popularization ofhomemade high-grade numerically-controlled machine tools in heavy-truck axle housing production lines are promoted.

Description

technical field [0001] The invention provides a processing technology for a stamped and welded axle housing, which relates to a machining process for a heavy truck axle housing, and mainly relates to a processing method for a heavy truck punched and welded axle housing disk inner hole, disk hole and through shaft hole based on a horizontal machining center. Background technique [0002] In the field of mechanical processing, especially in the automobile manufacturing industry, major changes have taken place in the processing technology and equipment of automobile axles, especially the equipment for heavy truck axle housing processing has gradually changed from special boring machines, ordinary boring machines, and CNC lathes to machining centers and compound cutting centers. And the production tempo has been significantly improved compared with the past. [0003] This invention comes from the major scientific and technological project of "High-end CNC Machine Tools and Basic...
