Description
technical field [0001] The invention relates to a processing device, in particular to a clamping device for processing the rear case of an automobile gearbox. Background technique [0002] At present, with the continuous improvement of people's living standards, automobiles have become a frequently used means of transportation. The automobile manufacturing industry is also developing rapidly. As people's requirements for the performance of automobiles are getting higher and higher, the requirements for machining accuracy of auto parts are also getting higher and higher. In the machining of the automatic transmission case, since the mating end faces of the rear case and the middle case of the case are very precise, high machining accuracy is required. In the process of processing, since the workpiece cannot be clamped at one time, the clamping needs to be changed back and forth to process two workpieces, which makes the processed workpiece have large errors and is difficult ...
