[0021] When it is necessary to grind the top or bottom surface of the car starting drive motor gear, the side baffle 2 is driven to rotate and move as a whole by starting the manipulator 10 until the bottom side of the isosceles triangle of the grinding belt 7 contacts the top or bottom surface of the car starting drive motor gear and stops, and then the driving mechanism 9 is started to make the first bevel gear 8 drive the fine transmission wheel 6 to rotate, and then the fine transmission wheel 6 drives the two coarse transmission wheels 4 to rotate synchronously through the grinding belt 7, so that the grinding belt 7 rotates to perform plane grinding on the top or bottom surface of the car starting drive motor gear. When the tooth groove of the starting drive motor gear is being polished, the side baffle 2 is driven by the manipulator 10 to rotate and move as a whole until the vertex angle side of the isosceles triangle of the polishing belt 7 contacts the tooth groove of the car starting drive motor gear and stops. Then the driving mechanism 9 drives the fine transmission wheel 6 to rotate through the first bevel gear 8, and then the fine transmission wheel 6 drives the coarse transmission wheel 4 to rotate through the polishing belt 7, and then the vertex angle side of the isosceles triangle of the polishing belt 7 rotates and polishes the tooth groove of the car starting drive motor gear. This design enables the equipment to perform both plane polishing and tooth groove polishing.

[0023] By starting the first drive motor 902, the rotating shaft 903 drives the square rod 904 to rotate, and then the square rod 904 drives the limiting round rod 906 to rotate along the inner wall of the fixed block 905, so that the limiting round rod 906 drives the first bevel gear 8 to rotate through the second bevel gear 907, and then the first bevel gear 8 drives the grinding belt 7 to rotate through the fine transmission wheel 6, and then the fine transmission wheel 6 drives the two coarse transmission wheels 4 to rotate through the grinding belt 7. At this time, if the tightness of the fine transmission wheel 6 and the coarse transmission wheel 4 to the grinding belt 7 is too low, the grinding belt 7 is easy to During the rotation process, it slips, and then the electric telescopic rod 18 is started to drive the moving frame 5 to move upward, thereby causing the moving frame 5 to drive the fine transmission wheel 6 to move upward, so that the fine transmission wheel 6 slowly pulls the grinding belt 7 to a suitable tightness and stops when it does not slip. At the same time, the moving frame 5 drives the limiting rod 906 to move along the outer surface of the square rod 904, so that the square rod 904 can still drive the first bevel gear 8 to rotate through the limiting rod 906 and the second bevel gear 907, so that the device can telescopically adjust the grinding belt 7 to rotate and grind the car starting drive motor gear; When the damaged grinding belt 7 needs to be replaced, the movable frame 5 is driven downward by the electric telescopic rod 18, and the movable frame 5 drives the fine transmission wheel 6 to move downward, and the fine transmission wheel 6 loosens the grinding belt 7. Then the operator can disassemble and replace the grinding belt 7, thereby achieving the purpose of facilitating the disassembly and replacement of the grinding belt 7.

Therefore, the equipment can grind the tooth grooves of the automobile starting drive motor gears of different sizes, thereby improving the use effect of the equipment; When it is necessary to grind the plane of the starting drive motor gear of different sizes of cars, the second drive motor 15 is started at this time, so that the rotating rod 16 drives the spur gear 17 to rotate, and then the spur gear 17 drives the two tooth groove blocks 12 to move along the inner wall of the sleeve frame 13, so that the tooth groove blocks 12 drive the two coarse transmission wheels 4 along the inner wall of the slide groove mouth 3 through the connecting rod 11 to move toward each other, so that the two coarse transmission wheels 4 loosen the grinding belt 7, and at the same time, by starting the electric telescopic rod 18, the mobile frame 5 drives the fine transmission wheel 6 to move downward to tighten the grinding belt 7. At this time, due to the movement of the two coarse transmission wheels 4, the grinding belt 7 is an isosceles triangle. The bottom side of the shape gradually shrinks until the bottom side of the isosceles triangle of the grinding belt 7 is the same size as the plane of the car starting drive motor gear, and then the side baffle 2 is driven to rotate and move as a whole by starting the manipulator 10 until the bottom side of the isosceles triangle of the grinding belt 7 contacts the plane of the car starting drive motor gear, and then the driving mechanism 9 is started, so that the first bevel gear 8 drives the fine transmission wheel 6 to rotate, and then the fine transmission wheel 6 drives the two coarse transmission wheels 4 to rotate synchronously through the grinding belt 7, so that the grinding belt 7 rotates to grind the plane of the car starting drive motor gear, thereby achieving the purpose of adjusting the grinding according to the size of the car starting drive motor gear plane.
