[0028] Two motor shaft end surface fixing components are arranged on the mounting plate 8 in a mirror-symmetrical manner. The motor shaft end surface fixing components are used to fix the end surface of the motor shaft. The motor shaft end surface fixing components include a short hexagonal sliding shaft 10, a V-shaped roller 12, a spring 13, a slot 15 and a long sliding block 17;

[0029] The motor shaft end surface fixing assembly also includes an inclined side plate 9, which is fixedly connected to one end of the mounting plate 8, and a hexagonal short sliding shaft 10 is slidably connected to the inclined side plate 9, and both ends of the hexagonal short sliding shaft 10 extend out of the outer surface of the inclined side plate 9;

[0030] The lower end of the hexagonal short sliding shaft 10 is fixedly connected to a roller fixing frame 11, and the V-shaped roller 12 is rotatably connected in the roller fixing frame 11. The spring 13 is sleeved on the outer surface of the hexagonal short sliding shaft 10, and the spring 13 is located between the inclined side plate 9 and the V-shaped roller 12.

[0031] Furthermore, the upper end of the hexagonal short sliding shaft 10 is fixedly connected to a movable plate 14 , a slot 15 is provided on the outer surface of the movable plate 14 , the upper surface of the mounting plate 8 is fixedly connected to a slide rail 16 , and a long slider 17 is slidably connected in the slide rail 16 .

[0036] Furthermore, when in use, the motor shaft whose end face needs to be polished is placed between the two electric rollers 2, and then the motor shaft limiting polishing assembly together with the two motor shaft end face fixing assemblies on the mounting plate 8 are turned down, and the handle 20 is manually rotated and twisted. Twisting the handle 20 can drive the elliptical cam 19 to rotate through the central axis 18, and the rotating elliptical cam 19 can drive the two long sliders 17 to move away from each other, so that the Teflon sliders 21 on the two long sliders 17 can apply a force to the inner wall of the slot 15, so that the movable plate 14 can be driven by its force to drive the hexagonal short slide shaft 10, the roller fixing frame 11 and the hexagonal short slide shaft 10 thereon to move obliquely upward until the spacing between the two V-shaped rollers 12 can match the two ends of the motor shaft. At this time, the V-shaped rollers 12 in the two motor shaft end face fixing assemblies can just limit the two ends of the motor shaft.

[0038] Working principle: When in use, place the motor shaft whose end face needs to be polished between the two electric rollers 2, then turn down the motor shaft limit polishing assembly together with the two motor shaft end face fixing assemblies on the mounting plate 8, and manually rotate and twist the handle 20. Twisting the handle 20 can drive the elliptical cam 19 to rotate through the central axis 18. The rotating elliptical cam 19 can drive the two long sliders 17 to move away from each other, so that the Teflon sliders 21 on the two long sliders 17 can apply a force to the inner wall of the slot 15, so that the moving plate 14 can be driven by its force to drive the hexagonal short slide shaft 10, the roller fixing frame 11 and the hexagonal short slide shaft 10 thereon.
