The intermediate hook is equipped with a compression spring 7; it also includes a limiting component, which is used for the grinding plate 2 to reciprocate, so that the pressure plate 4 first blocks the through hole 5, cooperates with the limit plate 6 to move the pressure plate 4 away from the through hole 5, so that the burr enters the movable groove 3, and finally resets the pressure plate 4 under the action of the compression spring 7, thereby squeezing the burr off the surface of the motor housing; a reciprocating component, the reciprocating component is used to drive the grinding plate 2 to reciprocate, thereby grinding the motor housing, and when the through hole 5 is separated from the motor housing, the gap stops, so that the burr is easy to be separated from the motor housing; In the present application, the grinding plate 2 is moved along the motor housing for grinding by reciprocating the grinding plate 2. During the grinding process, under the action of the limiting plate 6, the pressure plate 4 is kept stationary first, and the compression spring 7 is compressed to make the pressure plate 4 away from the through hole 5, thereby sucking out the burrs during the grinding process. Then, when the through hole 5 is away from the motor housing, it stays for a certain period of time, and under the action of the limiting plate 6, the restriction on the pressure plate 4 is released, so that the pressure plate 4 squeezes the through hole 5, and the burrs in the through hole 5 are discharged. This method ensures that the burrs are discharged in time, and avoids the detached burrs from not being removed in time, so that they are repeatedly retained between the motor housing and the grinding plate 2, and are repeatedly rubbed and polished, affecting the grinding effect.

[0019] The limiting assembly includes a first fixed block 8 connected and fixed to the top surface of the end of the grinding plate 2, and a plug rod 9 connected and fixed to the pressure plate 4 is movably inserted on the first fixed block 8. The pressure plate 4 is L-shaped, and the two ends of the compression spring 7 are respectively between the pressure plate 4 and the first fixed block 8. The compression spring 7 is movably wound around the outer surface of the plug rod 9. A first inclined surface 10 is provided at the end of the first fixed block 8, and a second inclined surface 11 is provided on the pressure plate 4. The limiting assembly also includes an L-shaped plate 12 connected and fixed to the base plate 1, the L-shaped plate 12 is rotatably connected to the limit plate 6 through a torsion spring, a second fixed block 13 that is pressed and matched with the end of the pressure plate 4 is fixedly connected to the middle of the end of the limit plate 6, a third inclined surface 14 that is matched with the first inclined surface 10 is formed at the end of the limit plate 6, a fourth inclined surface 15 that is matched with the second inclined surface 11 is formed on the second fixed block 13, and a baffle 16 that is pressed and matched with the limit plate 6 is fixedly connected to the bottom of the L-shaped plate 12; In the present application, under the action of the reciprocating assembly, the grinding plate 2 moves back and forth once, then stops moving, remains in the stopped state for a certain period of time, and then reciprocates again, and reciprocates in sequence; The process of a reciprocating grinding is as follows: First, when the grinding plate 2 moves to grind the motor housing, the pressing plate 4 blocks the through hole 5, and the grinding plate 2 drives the pressing plate 4 to move synchronously; Then, when the pressure plate 4 contacts the limiting plate 6, the pressure plate 4 is stopped under the action of the limiting plate 6, and the second fixed block 13 acts on the end of the pressure plate 4 and does not move with the grinding plate 2, while the grinding plate 2 continues to move, and the fixed plate 29 makes the insertion rod 9 move along the first fixed block 8, the compression spring 7 is compressed, and the pressure plate 4 moves along the movable groove 3, so that the pressure plate 4 is away from the through hole 5. During the grinding process of the grinding plate 2, the suction method of the pressure plate 4 makes the burrs (grinded off) on the motor housing enter the movable groove 3 through the through hole 5, so as to avoid the burrs that cannot be removed in time, thereby being repeatedly retained between the motor housing and the grinding plate 2, and repeatedly rubbed and polished, affecting the grinding effect; Then, when the grinding plate 2 continues to move and the through hole 5 is moved to a position away from the motor housing, the grinding plate 2 stops moving. When the first fixed block 8 contacts the limiting plate 6, the limiting plate 6 is rotated under the action of the first inclined surface 10 and the third inclined surface 14, so that the second fixed block 13 is rotated, and the limiting effect on the pressing plate 4 is released. Under the action of the compression spring 7, the pressing plate 4 moves along the movable groove 3, presses the movable groove 3 in the direction close to the through hole 5, and discharges the detached burrs in the movable groove 3 by squeezing air. Finally, the grinding plate 2 performs an in-situ reset motion and reciprocates in sequence to complete the reciprocating grinding motion.

[0020] The end of the grinding plate 2 is fixedly connected with a movable plate 17 that penetrates into the base plate 1. The vertical cross-section of the movable plate 17 is rectangular, which ensures that the grinding plate 2 reciprocates and grinds the motor housing horizontally without self-rotation.

[0021] The reciprocating assembly includes a servo motor 18 connected and fixed to the base plate 1. The base plate 1 is provided with a rotating groove 19. The output shaft of the servo motor 18 is fixedly connected to a rotating plate 20 rotating in the rotating groove 19. An arc plate 21 is rotatably connected in the rotating groove 19. A sliding groove 22 is provided on the arc plate 21. The end of the rotating plate 20 is slidably connected to the sliding groove 22. A matching plate 23 is rotatably connected between the top of the arc plate 21 and the grinding plate 2. The servo motor 18 starts to drive the rotating plate 20 to do circular motion. Under the action of the sliding groove 22, the arc plate 21 makes a reciprocating rotation at a certain angle, thereby driving the grinding plate 2 to do reciprocating grinding along the motor housing; Among them, when the sliding groove 22 (the sliding groove 22 is an arc-shaped structure) slides with the end of the rotating plate 20 (as shown in the figure, the end of the rotating plate 20 and the sliding groove 22 are in position), the arc plate 21 remains in position, and the rotating plate 20 continues to rotate, so that the grinding plate 2 stops for a certain period of time. At this time, the position of the through hole 5 moves to a position away from the motor housing, so that there is a certain amount of time for the detached burrs to be discharged from the through hole 5.

[0022] The through hole 5 located on the side of the grinding plate 2 is inclined, so that the burrs that fall off can be moved out of the through hole 5. A blocking plate 24 is fixedly connected to the pressure plate 4. A blocking groove 25 that slides with the blocking plate 24 is provided on the grinding plate 2 to ensure the sealing effect, so that other parts can only move from the through hole 5. It is worth noting that the through holes 5 on the same surface are distributed in a staggered manner.

[0023] The fixing part includes a gear column 26, and an embedding groove 27 is provided on the base plate 1 to be plugged and matched with the gear column 26. A plurality of fixing rods 28 are fixedly connected to the gear column 26 to be pressed and matched with the inner wall of the motor housing. The ends of the fixing rods 28 are inclined. Through the inclined angle of the fixing rods 28, the plurality of fixing rods 28 are pressed and fixed on the inner wall of the motor housing, and the motor housing and the grinding plate 2 are slidably matched. Finally, the motor housing is fixed through the plugging and matching of the gear column 26 and the embedding groove 27, so that the grinding plate 2 can reciprocate and grind the motor housing. In the present application, the gear column 26 is rotated to adjust the angle and then inserted into the embedded groove 27 to complete the grinding work of other groove positions of the motor housing. Alternatively, multiple grinding plates 2 and other structures may be provided on the base plate 1 to achieve simultaneous grinding of multiple groove positions of the motor housing.

[0024] Two fixing plates 29 for squeezing the motor housing are provided on the base plate 1. The fixing plate 29 close to the servo motor 18 is connected and fixed to the base plate 1, and the fixing plate 29 away from the servo motor 18 is plugged and fixed to the base plate 1. The motor housing is further fixed by the movable fixing plate 29.
