Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments; based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0024] Embodiment 1, given by Figures 1-4 The present utility model relates to a grinding and processing device for a motor rotor, including a bottom plate 1, side plates 2 symmetrically installed at the top end of the bottom plate 1, a top plate 3 installed at the bottom ends of the two side plates 2, a support component 4 installed between the two side plates 2, a fixing component 5 installed on the top plate 3, and a grinding component 6 installed at the top end of the bottom plate 1;

[0025] The support component 4 includes chutes 401 symmetrically opened on the sides of the two side plates 2 close to each other, two support rods 402 symmetrically arranged between the two side plates 2, sliders 403 symmetrically installed at both ends of the support rods 402, and the two sliders 403 are respectively slidably installed inside the chutes 401 on the two side plates 2. A double-headed screw 404 is rotatably installed inside one of the chutes 401, and the two sliders 403 at the same end of the two support rods 402 are respectively threadedly connected to two threaded grooves with opposite directions opened on the double-headed screw 404. One end of the double-headed screw 404 is fixedly connected to the output shaft of the first motor 405, and the first motor 405 is fixedly installed on the side plate 2.

[0026] The fixing component 5 includes a mounting plate 501 disposed below the top plate 3. Suction cups 502 are equidistantly mounted at the bottom end of the mounting plate 501. A negative pressure pump 503 is mounted at the top end of the mounting plate 501. The negative pressure pump 503 is connected to each suction cup 502. The suction cups 502 are located above the axis of symmetry between the two support rods 402. The top end of the mounting plate 501 is fixedly connected to the output ends of two first cylinders 504. The first cylinders 504 are fixedly mounted at the top end of the top plate 3. The mounting plate 501 moves downward until the bottom wall of the suction cup 502 is in close contact with the top wall of the rotor, limiting the rotor to facilitate rotor grinding. At the same time, the negative pressure pump 503 is turned on, so that a negative pressure is generated between the suction cup 502 and the rotor, fixing the rotor and preventing the rotor from rotating during grinding, improving the grinding stability.

[0027] The grinding component 6 includes a grinding roller 601 disposed below the axis of symmetry between the two support rods 402. A moving table 603 is provided below the grinding roller 601. Two support plates 602 are symmetrically mounted at the top end of the moving table 603. The two support plates 602 are symmetrically disposed at both ends of the grinding roller 601. The rotating shaft of the grinding roller 601 is rotatably connected to the support plate 602. The top wall of the grinding roller 601 is higher than the top end of the support plate 602. One end of the rotating shaft of the grinding roller 601 is fixedly mounted with a first gear 604. A second gear 605 is meshed and connected below the first gear 604. The second gear 605 is fixedly connected to the output shaft of a second motor 606. The second motor 606 is fixedly mounted on a motor mounting frame, and the motor mounting frame is mounted on the support plate 602. The bottom end of the moving table 603 is fixedly connected to the output ends of two second cylinders 607. The second cylinders 607 are fixedly mounted on the bottom plate 1. After the two support rods 402 approach each other, they support the rotor, facilitating the support of rotors of different sizes. At the same time, the grinding roller 601 is disposed below the axis of symmetry of the two support rods 402, so that after the grinding roller 601 moves upward, it can be in full contact with the rotor in the length direction, facilitating grinding, avoiding occlusion on the length direction of the outer surface of the rotor, and improving the grinding effect.

[0028] Working principle: During operation, first place the rotor to be ground between the two support rods 402, turn on the first motor 405, so that the double-headed screw 404 rotates, thereby driving the two support rods 402 to approach each other until the two support rods 402 contact the outer wall of the rotor, thus supporting the rotor, and setting the position of the rotor to be ground downward;

[0029] Subsequently, turn on the first cylinder 504, so that the mounting plate 501 moves downward until the bottom wall of the suction cup 502 is in close contact with the top wall of the rotor, limiting the rotor to facilitate rotor grinding. At the same time, turn on the negative pressure pump 503, so that a negative pressure is generated between the suction cup 502 and the rotor, fixing the rotor and preventing the rotor from rotating during grinding, improving the grinding stability;

[0030] Subsequently, the second cylinder 607 is activated, causing the grinding roller 601 to move upward until the outer wall of the grinding roller 601 comes into contact with the position of the rotor that needs to be ground below. Then, the second motor 606 is activated, causing the second gear 605 to rotate. Since the second gear 605 meshes with the first gear 604, the grinding roller 601 is driven to rotate to grind the position of the rotor that needs to be ground.
