Machining clamp for automobile differential shell

The utility model discloses an automobile differential shell processing clamp, which relates to the technical field of differential shell processing and comprises a rotating seat, the top end of the rotating seat is rotatably connected with a processing table, four corners of the top of the processing table are fixedly connected with supports, and a laser calibrator is fixedly mounted at the midpoint of the top surface of the processing table. Clamping assemblies are fixedly connected to the inner sides of the four supports, and calibration assemblies are fixedly connected to the outer surfaces of the top ends of the four supports. According to the utility model, the differential housing is fixed through the clamping assembly, the special-shaped differential housing can also be fixed and stabilized through independent adjustment, and after the differential housing is fixed and stabilized, the laser calibrator emits vertical infrared laser to be matched with the calibration assembly.
