Problems solved by technology
[0003] The present invention aims to solve the above-mentioned problems, and provides a processing system and processing method for an automobile differential case, which effectively solves the ubiquitous problem of using traditional methods to process the outer circle and difference of the bearing installation positions at both ends of the differential case. It is difficult to install the spherical arc surface of the inner gear of the gearbox housing, which improves the machining accuracy and efficiency, and greatly reduces the scrap rate. The technical scheme adopted is as follows:

The invention belongs to the field of machining, and in particular relates to a machining system and a machining method for machining the outer circle of the bearing installation positions at both ends of the differential case and the spherical arc surface of the inner gear of the differential case. The automobile differential housing processing system is mainly composed of an outer circle processing lathe for the bearing installation positions at both ends of the differential housing, a spherical arc surface processing lathe for the internal gear installation of the differential housing, and a control system; The bearing installation position cylindrical machining lathe includes: the first fuselage, the main shaft, the pneumatic tailstock and the first tool; the differential case internal gear installation spherical arc surface machining lathe includes: the second fuselage, the left power head, the right power head , Positioning clamping device and tool changing device. It improves the machining accuracy and efficiency, greatly reduces the scrap rate, and effectively solves the difficulty of machining the outer circle of the bearing installation positions at both ends of the differential housing and the spherical arc surface of the inner gear of the differential housing, which are commonly used in traditional methods. big problem.
Description
technical field [0001] The invention belongs to the field of mechanical processing, and in particular relates to a processing system and a processing method for processing the outer circle of the mounting positions of the bearings at both ends of the differential housing and the spherical arc surface of the inner gear of the differential housing. Background technique [0002] Now for the processing of the differential housing of the miniature car, there are mainly two processing difficulties ( figure 1 As shown), the first difficulty is the processing of the outer circle 11 of the bearing installation position at both ends of the differential case. The coaxiality requirement is high, and the tolerance is within ￠0.05mm. The processing of the arc surface 12 is difficult to meet the shape and position tolerance due to the small processing space and high performance requirements. For the processing of the first point, the method of processing one end on the lathe and turning a...
