Second support rods rotatably connected to the base and passing through the bottom of the base are provided at the bottoms of the main abrasive belt wheel and the grinding wheels.

[0007] Further, the driving component includes a motor fixedly arranged at the bottom of the base. A belt pulley is provided at the end of the second support rod below the base. The output end of the motor is fixedly connected to the bottom of one of the belt pulleys. A matching belt is provided between the belt pulleys.

[0008] Further, the clamping component includes symmetrically arranged electric push rods. A clamping plate slidably connected to the top of the base is fixedly connected to the telescopic rod end of the electric push rod.

[0009] Furthermore, a limiting rail matching the clamping plate is provided at the top of the base.

[0010] Furthermore, the gap distance between the outer wall of the grinding abrasive belt and the wheel wall of the grinding wheel is 0.1 - 1 mm.

[0011] Advantages of the present utility model:

[0012] The reducer housing in a triangular distribution is clamped and fixed between the clamping plates by the clamping assembly, and the outer wall of the reducer housing is pressed against the outer wall of the grinding abrasive belt and the inner wall is pressed against the wheel wall of the grinding wheel. By the driving assembly, starting one motor drives the grinding abrasive belt and the grinding wheel to rotate simultaneously, reducing the waste of electric power resources and effectively reducing the comprehensive cost. The rotation of the grinding abrasive belt and the grinding wheel can simultaneously grind the outer walls and inner walls of multiple reducer housings. Compared with the traditional method where only the inner wall or the outer wall of a single reducer housing can be ground each time, the grinding efficiency is effectively improved.
