[0002] The automobile drive axle is an important component of the automobile transmission system. It is located at the end of the transmission system. Its main function is to change the speed and torque from the transmission and transmit these powers to the drive wheels, thereby driving the car. The automobile drive axle housing refers to the outer shell of the automobile drive axle. Its main function is to support and protect key components such as the main reducer, differential, and half-axles. It is divided into integral bridge housing, segmented bridge housing and combined bridge housing.

[0003] A fixture is a device used to keep an object or component in position. It is widely used in many fields, such as manufacturing and construction. It includes machine tool fixtures, combination fixtures, elastic fixtures and workpiece positioning fixtures.

[0004] The authorization publication number "CN108555636A" records "a fixing device for processing automobile drive axle bridge housings, comprising an operating table, a bearing table, a bearing plate, an adjusting screw, an adjusting plate, a cylinder and a pressure plate, characterized in that: the operating table is arranged on the bracket, the positioning plate is provided with an adjusting slot, the bearing table is provided with a mounting plate and a connecting slot, one end of the bearing plate is arranged in the connecting slot, the adjusting screw passes through the fixing slot, connecting rod one and connecting rod two are provided on opposite sides of one end of the adjusting plate, the cylinder is arranged on the adjusting plate, and a power cord and a piston rod are provided on the cylinder, and the pressure plate is arranged on the piston rod. The present invention sets the bearing table to a structure that can be moved on the operating table through the mounting plate and the mounting bolts. According to the different sizes of the drive axle bridge housings, the position of the bearing table on the operating table is adjusted, which is convenient for fixing the drive axle bridge housings of different sizes and improves the stability of the drive axle bridge housings on the fixing device."

[0005] The above patent is set as a structure that can be moved on the operating table through the mounting plate and the mounting bolts. The position of the bearing platform on the operating table is adjusted according to the different sizes of the drive axle housings, which is convenient for fixing the drive axle housings of different sizes and improving the stability of the drive axle housing on the fixing device.
