Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0033] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features and technical solutions therein can be combined with each other.

[0034] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, it does not need to be further defined or explained in subsequent drawings.

[0035] like Figure 1-6 As shown, this embodiment provides a polishing device for motor rotor processing, including an operating table 1, a polishing mechanism 2 is provided on one side of the operating table 1, a spraying component 3 is provided on one side of the operating table 1, and a smoke exhaust component 4 is provided on one side of the operating table 1;

[0036] The polishing mechanism 2 includes a first servo motor 201, a screw rod 202, a support platform 203, a second motor 204, a stabilizing frame 205, a screw rod 206, a sliding plate 207, an extrusion frame 208, a bracket 209, a hydraulic rod 210, a fixed frame 211, a third motor 212 and a polishing wheel 213.

It is fixedly connected to the top of the operating table 1, the hydraulic rod 210 is arranged at the bottom of the bracket 209, the fixed frame 211 is arranged at the bottom of the hydraulic rod 210, the third motor 212 is bolted to one side of the fixed frame 211, and the polishing wheel 213 is fixedly connected to the output end of the third motor 212. The motor rotor is placed between the stabilizing frame 205 and the extrusion frame 208. The screw 206 is manually rotated to make the sliding plate 207 and the extrusion frame 208 slowly approach the stabilizing frame 205 to clamp and fix the motor rotor. The third motor 212 is started to make the polishing wheel 213 rotate at high speed. The hydraulic rod 210 is started to make the fixed frame 211 slowly descend so that the polishing wheel 213 contacts the motor rotor for polishing. The first servo motor 201 is started to make the screw rod 202 rotate, thereby driving the support platform 203 and the fixed motor rotor to move. When used in conjunction with the hydraulic rod 210, it can prevent the motor rotor from having a polishing dead angle.

[0037] Taking into account that large friction and heat will be generated when polishing the motor rotor, the spray assembly 3 includes a storage box 301, a water inlet pipe 302, an extraction pipe 303, a water pump 304 and a hose 305. The storage box 301 is fixedly connected to the top of the bracket 209, the water inlet pipe 302 is fixedly connected to one side of the storage box 301, the extraction pipe 303 is fixedly connected to one side of the storage box 301 and is connected to the interior of the storage box 301, the water pump 304 is arranged on one side of the extraction pipe 303 and on the top of the bracket 209, the hose 305 is arranged at the output end of the water pump 304, one end of the hose 305 is fixedly connected to one side of the fixed frame 211 and the bottom of the hose 305 faces the polishing wheel 213, the liquid polishing agent can be injected into the storage box 301 through the water inlet pipe 302, and by starting the water pump 304, the liquid polishing agent can be extracted and sprayed on the motor rotor after passing through the hose 305, thereby reducing the friction and heat generated during polishing.

[0038] Taking into account that the motor rotor will generate waste smoke during polishing, the smoke exhaust component 4 includes an extraction frame 401, a suction pipe 402, an exhaust fan 403 and an exhaust pipe 404. The extraction frame 401 is fixedly connected to the top of the operating table 1 and is passed through the bracket 209. The suction pipe 402 is fixedly connected to the bottom of the extraction frame 401. The exhaust fan 403 is arranged at the bottom of the suction pipe 402. The exhaust pipe 404 is arranged on one side of the exhaust fan 403. The exhaust fan 403 can suck the waste smoke generated by the motor rotor during polishing from the suction frame into the suction pipe 402, and then discharge it from the exhaust pipe 404.

[0039] Taking into account that the debris generated after the polishing of the motor rotor will be wetted by the liquid polishing agent and will be inconvenient to clean, a sewage discharge frame 5 is fixedly connected to one side of the support platform 203, and a slide groove 6 is provided inside the operating table 1. The outer wall of the sewage discharge frame 5 is slidably connected to the inner wall of the slide groove 6. The movement of the support platform 203 will drive the sewage discharge frame 5 to slide in the slide groove 6. The polishing debris washed down by the liquid polishing agent will fall on the operating table 1. After being guided by the sewage discharge frame 5, it will fall elsewhere to prevent the accumulation of debris.

[0040] Taking into account that the surface of the motor rotor needs to be cleaned in time during polishing, a fixed rod 7 is fixedly connected to one side of the fixed frame 211, and the outer wall of the fixed rod 7 is rotatably connected to a rotating roller 8. The outer wall of the rotating roller 8 is provided with a polishing cloth 9. During polishing, the rotating roller 8 and the polishing cloth 9 follow the fixed frame 211 to descend and contact the outer wall of the rotating motor rotor, so that the polishing debris attached to the outer wall of the motor rotor can be cleaned in time.

[0041] Taking into account that the support platform 203 will shake as the screw rod 202 rotates, a stabilizing rod 10 is fixedly connected to one side of the operating platform 1, and the support platform 203 is slidably connected to the outer wall of the stabilizing rod 10. When the operating platform 1 moves, it will slide on the outer wall of the stabilizing rod 10, thereby improving the stability of the support platform 203 when moving.

[0042] Taking into account that the debris generated during polishing may affect the use of the screw 206, a shielding plate 11 is fixedly connected to one side of the sliding plate 207. The shielding plate 11 is tightly fitted to one side of the support platform 203. The shielding plate 11 will move with the movement of the sliding plate 207 to shield the screw 206, preventing the debris generated during polishing from affecting the normal use of the screw 206.

[0043] Specifically, when the polishing device for motor rotor processing is used: the motor rotor is placed between the stabilizing frame 205 and the extruding frame 208, the screw 206 is rotated to make the sliding plate 207 and the extruding frame 208 slowly approach the stabilizing frame 205, the motor rotor is clamped and fixed, the third motor 212 is started, the polishing wheel 213 rotates at high speed, the hydraulic rod 210 is started, the fixing frame 211 is slowly lowered, and the polishing wheel 213 contacts the motor rotor for polishing. During polishing, the rotating roller 8 and the polishing cloth 9 contact the outer wall of the rotating motor rotor, and then rotate synchronously, the water pump 304 is started, and the liquid polishing agent is extracted from the extraction pipe 303 and passed through the hose 305. Then it is sprayed onto the polishing wheel 213 and the polishing cloth 9 to wipe off the debris generated by polishing on the motor rotor and improve the polishing effect. Starting the first servo motor 201 can make the screw 202 rotate, thereby driving the support platform 203 and the fixed motor rotor to move. Used in conjunction with the hydraulic rod 210, it can prevent the motor rotor from having a polishing dead angle. Starting the exhaust fan 403 can suck the waste smoke generated during polishing from the suction frame into the suction pipe 402, and then discharge it from the exhaust pipe 404. The debris will fall onto the operating table 1 after mixing with the liquid polishing agent, and will fall elsewhere after being guided by the sewage discharge frame 5. The chute 6 can allow the sewage discharge frame 5 to move with the operating table 1.

[0044] All technical features in this embodiment can be freely combined according to actual needs.

[0045] The above embodiments are preferred implementation schemes of the present invention. In addition, the present invention can also be implemented in other ways. Any obvious replacement without departing from the concept of the present technical solution is within the scope of protection of the present invention.
