Abstract

The invention provides a clamp for a milling joint face of a gearbox shell and a use method of the clamp. The clamp comprises a bottom plate. Countersinks corresponding to assembling holes in the shell in position are formed in the bottom plate. A pressing device is arranged on each countersink. Fixed pressing force can be set on each pressing device. A stop dog device clamped to the turning faceof the shell and a support device with the height adjusting and height self-locking functions are arranged on the bottom plate. The use method of the clamp comprises the steps that (1), a workpiece isclamped; (2), the workpiece is tensioned by oil cylinders; and (3), the workpiece is abutted by the support device and locked. The clamp and the use method have the beneficial effects that the degreeof automation is high, the clamping pressure is fixed, the problems of tool vibration, extremely-poor flatness and the like existing in the clamping and machining processes of the thin wall shell aresolved, and the machining accuracy of the milling joint face of the gear shell is guaranteed.

Description

technical field [0001] The invention relates to the technical field of clamping devices, in particular to a clamp for milling joint surfaces of gearbox casings and a method for using the same. Background technique [0002] The gearbox housing belongs to the cavity type thin-walled parts. The housing is provided with assembly holes for assembling bearings and brake discs and other components. For oil filling and oil draining, the housing is provided with oil filling holes and oil drain holes. In order to keep the inside of the gearbox at atmospheric pressure, the housing is also provided with There are several ventilation holes. [0003] In the machining process of the gearbox housing, the machining of the milling joint surface is a very important process in the machining process of the gearbox housing, and its machining accuracy will directly affect the product quality of the gearbox housing. Since this type of shell is a thin-walled part, there are problems of tool vibrat...
