The axle housing is the base for installing the main reducer, differential, half shaft and wheel assembly. Its main function is to support and protect the main reducer, differential and half shaft. Generally speaking, the ordinary non-disconnecting drive axle housing is a rigid hollow beam supported on the left and right driving wheels. The main reducer, differential, half shaft and other transmission parts are installed in it. The axle housing is connected to the frame or carriage through the longitudinal leaf spring. It is an important part of the drive axle and one of the main components of the running system. The drive axle housing should have sufficient strength and rigidity, small mass, and easy to disassemble and adjust the main reducer. The drive axle housing can be divided into three types from the structural point of view: integral axle housing, separable axle housing and combined axle housing. The surface of the automobile drive axle housing needs to be polished with a polishing device during production.

[0025] Among them, a dust box 11 is fixedly connected to one side of the top of the fixed box 1, and a collecting box 12 is fixedly installed inside the fixed box 1. One side of the collecting box 12 is connected to the dust box 11 through a dust suction pipe 13. By setting up the dust box 11, it is beneficial to collect the dust generated during the grinding process more thoroughly and avoid pollution of the working environment.

[0026] Among them, one side of the collecting box 12 is connected to an exhaust fan 14, the inside of the dust box 11 is detachably connected to a filter plate 15, one side of the dust box 11 is provided with a dust suction port 16, and one side of the collecting box 12 is rotatably connected to a box door 17. By setting the filter plate 15, the absorbed dust can be filtered through the filter plate 15 and stored in the collecting box 12, which can facilitate the cleaning of the dust in the collecting box 12.

[0027] Among them, the top of the fixed box 1 is fixedly connected with a support column 18, the top of the support column 18 is fixedly connected with a mounting frame 19, one side of the mounting frame 19 is bolted to a power motor 20, the output end of the power motor 20 is transmission-connected with a ball screw 21, and the outer peripheral thread of the ball screw 21 is connected to the support frame 22. By setting the mounting frame 19, the grinder 26 can be driven to move vertically.

[0028] Among them, one end of the support frame 22 is bolted to a servo motor 23, the output end of the servo motor 23 is transmission-connected to a ball screw 24, the outer side of the ball screw 24 is threadedly connected to a connecting frame 25, and a grinder 26 is fixedly installed inside the connecting frame 25. By setting the support frame 22, the grinder 26 can be driven to move laterally, and the positioning of the grinder 26 can be adjusted according to the position of the bridge housing to expand the grinding range and effectively ensure the certainty of the grinding.

[0029] Among them, the upper end of the base 8 is fixedly connected with a circular ring 27, and an arc plate 28 is arranged inside the circular ring 27. By setting the circular ring 27, the accurate positioning of the fixture of the bridge housing can be ensured, the grinding quality can be improved, and the certainty of grinding can be effectively guaranteed.

[0030] Among them, a threaded rod 29 is arranged on the top of the arc plate 28 through a coupling, and a handle 30 is fixedly connected to the top of the threaded rod 29. An anti-slip pad is arranged on the surface of the arc plate 28. By setting the threaded rod 29, the arc plate 28 can be supported against the bridge housing body through the threaded rod 29, thereby reducing its vibration during grinding and improving the stability of the device.

[0031] Working principle: When in use, place the drive axle housing that needs to be polished on the U-shaped plate 2, and adjust the distance between the ring 27 and the drive axle housing by sliding the sliding block 9 on the U-shaped plate 2, which is conducive to adapting to the drive axle housing structure of different lengths. Place the bridge housing on the rings 27 on both sides, and rotate the handle 30 to make the arc plate 28 support the bridge housing body, so that the bridge housing can be fixed and accurately positioned, reducing its vibration during polishing and improving the stability of the device. Start the power motor 20 to drive the ball screw 1 21 to rotate, so that the support frame 22 moves to the top of the bridge housing, start the servo motor 23, drive the ball screw 24 to rotate, adjust the grinder 26 to the position that needs to be polished, and start the grinder 26 for polishing. At the same time, the exhaust fan 14 is started. The exhaust fan 14 collects dust on the bridge shell being polished through the collection box 12 and the dust suction pipe 13 through the dust suction box 11, which is conducive to more thorough collection of dust generated during the polishing process and avoids pollution of the working environment. The absorbed dust can be filtered through the filter plate 15 inside the collection box 12 and stored in the collection box 12. Then, the box door 17 is rotated to facilitate cleaning of the dust in the collection box 12. When the angle of the bridge shell needs to be adjusted during polishing, the drive motor 3 is started to drive the active wheel 4 to rotate, and the driven wheel 6 is driven by the belt 5 to rotate, so that the bridge shell rotates and the angle is adjusted, instead of manually turning the bridge shell, so that the polishing process is not only safe, but also saves time and effort and the work efficiency is greatly improved.
