A lifting screw 108 is threadedly sleeved on the bottom end of the workbench 101, and the upper end of the lifting screw 108 is rotatably connected to the bottom end of the movable plate 102, and an auxiliary rod is passed through the bottom end of the lifting screw 108. By rotating the lifting screw 108, the lifting screw 108 is moved upward, and at the same time, the movable plate 102 is driven to move upward, so as to achieve corresponding adjustments according to instrument panels of different thicknesses.

[0041] Example 2: Please refer to Figure 3 - Figure 5 , an electric vehicle instrument panel polishing device and a method of using the same, based on the first embodiment, the outer surface of the passive tube 206 is fixedly sleeved with a driving gear 208, the end of the driving cylinder 301 away from the liquid outlet cover 304 is rotatably mounted with a passive ring 302, and the outer surface of the passive ring 302 is fixedly sleeved with a passive gear 209, two adjacent passive gears 209 are meshed with each other, wherein the passive gear 209 close to the passive tube 206 is meshed with the driving gear 208;

[0042] The outer surface of the passive tube 206 is sleeved with a shunt ring 203, and the shunt ring 203 is connected to the infusion tube 4 through a guide tube 204. The upper end of the passive ring 302 is sleeved with a sealing cover 303, and the outer surface of the sealing cover 303 is fixedly connected to the inner end of the outer support shell 205, wherein the sealing cover 303 close to the passive tube 206 is connected to the output end of the shunt ring 203, and two adjacent sealing covers 303 are connected by a synchronization tube 305, and the polishing liquid flowing out of the infusion tube 4 flows into the interior of the sealing cover 303 through the guide tube 204 and the shunt ring 203.

[0043] See also Figure 5 - Fig. 9The extraction device includes a passive turbofan 315, which is fixedly connected to the inside of the passive ring 302. An isolation plate is fixedly welded to the inner upper end of the driving cylinder 301, and a plurality of holes are provided on the outer surface of the isolation plate. A movable plug 306 is slidably connected to the inner end of the driving cylinder 301. A sealing rubber ring is fixedly sleeved on the outer surface of the movable plug 306, and the sealing rubber ring is tightly fitted with the inner wall of the driving cylinder 301 to improve the sealing performance. Two matching cylinders 313 are fixedly connected to the inner end of the driving cylinder 301. The upper ends of the two matching cylinders 313 are both penetrated with flow guide tubes 314. The outer surfaces of the flow guide tubes 314 are fixedly sleeved with sealing rubber rings and fit with the inner wall of the matching cylinder 313 to improve the sealing performance. Two through holes are provided on the outer surface of the movable plug 306, and one end of the flow guide tube 314 away from the matching cylinder 313 is fixedly penetrated in the through hole and communicated with the chamber above the movable plug 306.

[0044] Specifically, a guide rod 501 is fixedly welded to the inner end of the matching cylinder 313, and the guide tube 314 is sleeved on the outer surface of the guide rod 501. The outer surface of the guide rod 501 is provided with a plurality of annular guide grooves 503 with gradually decreasing heights. When the guide tube 314 moves downward, the guide grooves 503 are gradually wrapped by the guide tube 314, thereby increasing the channel volume for liquid flow, and the guide tube 314 and the matching cylinder 313 are connected by abutment springs 502.

[0045] The upper end of the liquid outlet cover 304 is fixedly connected with a ball shell 310, and the ball shell 310 is movably installed at the bottom end of the driving cylinder 301.

[0046] Specifically, the rotating shell 207 is made of soft rubber, the liquid outlet cover 304 is exposed for a distance from the bottom end of the outer supporting shell 205, and its bottom end is in contact with the inner end of the rotating shell 207. The diameter of the through hole at the bottom end of the outer supporting shell 205 is larger than the diameter of the liquid outlet cover 304. When the rotating shell 207 encounters an irregular area of ​​the instrument panel during rotation, it produces adaptive deformation, and at the same time causes the liquid outlet cover 304 to deviate accordingly.

[0047] The inner end of the movable cylinder 318 is penetrated by a central tube 308, and the matching cylinder 313 is connected to the central tube 308 via a return pipe 307. A balancing ring 317 is fixedly welded to the outer surface of the movable cylinder 318, and an extrusion ring 312 is arranged on the upper end of the balancing ring 317. The outer surface of the extrusion ring 312 abuts against the inner wall of the driving cylinder 301, and the diameter of the balancing ring 317 is smaller than that of the extrusion ring 312. Therefore, when the movable cylinder 318 deviates, the balancing ring 317 is driven to move, and the edge of the balancing ring 317 pushes the extrusion ring 312 to move upward.

[0048] like Figure 5 , Figure 7 , Figure 8 , Fig. 9 As shown, the outer surface of the movable cylinder 318 is sleeved with an airbag 309, and the airbag 309 is located above the extrusion ring 312, and the upper part of the airbag 309 abuts against the bottom ends of the two matching cylinders 313. A spring piece is provided inside the airbag 309. When the airbag 309 is deformed by force, it can be restored to its initial state under the elastic force of the spring piece. The airbag 309 and the movable cylinder 318 are connected by an air pipe 316 composed of an elastic hose. The connection between the air pipe 316 and the movable cylinder 318 adopts a sealed bearing structure, which not only ensures air tightness, but also effectively prevents the air pipe 316 from being entangled and knotted during movement.

[0049] A passive plug 504 is fixedly installed on the outer surface of the central tube 308, and the passive plug 504 is located above the output port of the trachea 316. Specifically, a plurality of limit blocks are fixedly installed on the inner end of the movable cylinder 318, and the limit blocks are located below the passive plug 504 to prevent the passive plug 504 from blocking the output port of the trachea 316.

[0050] A plurality of leakage holes 506 are provided at the bottom end of the sealing cover 303, and the leakage holes 506 are arranged in a ring shape. A plurality of movable spring pieces 505 are slidably installed at the inner bottom end of the sealing cover 303. The movable spring pieces 505 are made of elastic metal material, and the ends of the movable spring pieces 505 are fixedly connected to the outer surface of the central tube 308. A plurality of auxiliary wheels are rotatably installed at the inner end of the liquid outlet cover 304. The outer surfaces of the auxiliary wheels contact the movable spring pieces 505 and change their directions, so that the movable spring pieces 505 block the leakage holes 506 and retain an opening. A plurality of holes are provided on the outer surface of the central tube 308 and are exposed inside the sealing cover 303.

[0051] Example 3: Please refer to Figure 4 , Fig.10 , a polishing device for an electric vehicle instrument panel and a method for using the same, based on embodiments 1 and 2, a filter cotton 403 is inserted into the inner end of a recovery cylinder 401, and the upper and lower ends of the filter cotton 403 are fixedly connected to a stabilizing ring, and the two stabilizing rings are fixed to each other to support the filter cotton 403 to prevent collapse, and a passive sleeve 404 is slidably installed on the inner end of the recovery cylinder 401, and the passive sleeve 404 is connected to the recovery cylinder 401 through a limit spring, and liquid outlet holes 405 are provided on the outer surfaces of the passive sleeve 404 and the recovery cylinder 401, and the two liquid outlet holes 405 correspond to each other, and when the filter cotton 403 moves up, the passive sleeve 404 is pushed to move, so that the two liquid outlet holes 405 are displaced from each other;

[0052] The upper end of the recovery cylinder 401 is fixedly connected with a recovery pipe 402 , and the free end of the recovery pipe 402 is connected to the synchronization pipe 305 .

[0053] like Figure 1 , Fig.11 As shown, a liquid groove is provided at one end of the outer support shell 205 close to the rotating shell 207 to facilitate the flow of liquid, and a plurality of liquid holes are provided on the outer surface of the rotating shell 207 corresponding to the liquid groove. A controller is also provided at the upper end of the workbench 101 to control the start and stop of the device and the start and stop of the water pump inside the liquid storage barrel 2. This is an existing mature technology and will not be elaborated here.

[0054] The working principle of the present invention is:

[0055] When in use, the instrument panel to be polished is placed on the top of the matching frame 103, and then clamped by the clamping rod 107, and then the polishing motor 202 is started, and its output end drives the rotating shell 207 to rotate through the passive tube 206, and the polishing cloth sleeved on the outer surface of the rotating shell 207 contacts the outer surface of the instrument panel. When the passive tube 206 rotates, it drives the driving gear 208 to rotate, and the passive gear 209 drives the passive ring 302 to rotate under the action of meshing with it, and the water pump inside the liquid storage barrel 2 starts to extract a small amount of polishing liquid into the inside of the diverter ring 203. When the passive ring 302 rotates, it drives the passive turbofan 315 to rotate, and the polishing liquid inside the diverter ring 203 is pumped into the inside of the driving cylinder 301. At the same time, the two driving motors 7 respectively drive the traveling screw 51 and the adjusting screw 61 to rotate, so that the movable beam 5 and the sliding shell 201 move;

[0056] Then, the polishing liquid comes to the top of the movable plug 306, and drives the movable plug 306 to move downward under the action of pressure. As the movable plug 306 moves downward, it drives the guide pipe 314 to move downward and cover the guide groove 503, so that the polishing liquid flows through the guide groove 503 and enters the interior of the central tube 308 through the return pipe 307. If the instrument panel needs a large flow of polishing liquid to assist in polishing, the power of the water pump is increased through the control of the controller, so that the polishing liquid flows into the interior of the driving cylinder 301 in large quantities. The movable plug 306 continues to move downward under the action of pressure and wraps all the guide grooves 503 on the outer surface of the guide rod 501, thereby increasing the channel volume of the liquid flow (the water pump stops working after working for a period of time under the control of the controller);

[0057] At the same time, after the polishing liquid enters the liquid outlet cover 304 from the central tube 308, it flows out through the leakage hole 506, and then soaks the polishing cloth through the liquid holes on the outer surface of the rotating shell 207, which not only assists the instrument panel polishing operation, but also effectively reduces the temperature generated by friction. In order to prevent the polishing liquid from being thrown out by the rotating rotating shell 207, the passive turbofan 315 extracts the polishing liquid attached to the outer surface of the instrument panel through the recovery tube 402 and the recovery cylinder 401 when rotating. After being wetted, the filter cotton 403 generates an upward adsorption force, which drives the passive sleeve 404 to move upward synchronously, resulting in the displacement of the passive sleeve 404 and the liquid outlet hole 405 on the surface of the recovery cylinder 401. At this time, the liquid can enter the interior of the driving cylinder 301 along the recovery tube 402, thereby realizing the reuse of the polishing liquid.

[0058] If the rotating shell 207 reaches the edge of the instrument panel (or the irregular area of ​​the instrument panel), the rotating shell 207 will produce adaptive deformation in the irregular area, and at the same time drive the liquid outlet cover 304 to deviate accordingly, the movable cylinder 318 will deviate, drive the balance ring 317 to move, and the edge of the balance ring 317 will push the extrusion ring 312 to move upward, so that the air bag 309 is deformed by force, and the gas inside is squeezed. The gas inside enters the inside of the movable cylinder 318 from the air pipe 316, and the passive plug 504 moves upward under the pressure of the gas, and drags the movable spring piece 505 to expose the remaining leakage holes 506, so as to increase the liquid outlet efficiency and avoid the situation that the irregular area of ​​the instrument panel cannot contact the polishing liquid in time;

[0059] When the rotating shell 207 returns to the flat area, the liquid outlet cover 304 returns to the horizontal state, and the airbag 309 also returns to the initial state, so that the central tube 308 moves downward and pushes the movable spring sheet 505 to the initial state.
