[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figures 1 to 4This utility model provides a technical solution: a gear shift lever grinding and polishing device, including an operating table 1, on which two fixed plates 2 are provided, and pneumatic telescopic rods 3 and distance sensors 9 are respectively fixed on the two fixed plates 2. The distance sensors 9 are commercially available HG-C1100 laser displacement sensors. The pneumatic telescopic rods 3 are respectively connected to grinding plates 4 for grinding and polishing the gear shift lever. The grinding plates 4 include a grinding plate shell 41, and a plurality of rectangularly arranged springs 42 are welded inside the grinding plate shell 41. The other end of the plurality of rectangularly arranged springs 42 is provided with a fixed... The spring groove 45 of the fixed spring has a sponge pad 43 attached to the other side of the spring groove 45 by Velcro, and a sanding paper 44 is attached to the other side of the sponge pad 43 by Velcro. The sanding paper 44 can be easily attached to the sponge pad 43. It is very convenient to replace the sanding paper when it is worn out. The sanding plate 4 has a sliding groove 6 below it, and a slider that can slide along the sliding groove 6 is set at the bottom of the sanding plate 4. The sanding plate 4 slides in the middle of it. The main purpose is to move the two sanding plates 4 closer to the shift lever to be sanded when working with the pneumatic telescopic rod 3, so that it can be wrapped up more smoothly and stably. The operating table 1 is equipped with a grinding device 5, which includes a fixed housing 52. Inside the fixed housing 52 is a grinding motor 51. The other end of the grinding motor 51 is connected to a three-jaw pneumatic chuck 53. The three-jaw pneumatic chuck is a commonly used automatic clamping device on CNC machine tools, specifically model BK160250320SQ CNC lathe parts. An air hose 54 is connected to the three-jaw pneumatic chuck 53, through which air is pumped, causing the three-jaw pneumatic chuck 53 to tightly grip the shift lever. Then, the grinding motor 51 operates, driving the three-jaw chuck to rotate. A collection trough 7 is welded to the bottom of the operating platform 1. Below the collection trough 7 is a collection box 8 for collecting iron filings, dust, and the shift lever. The collection box 8 is composed of a material collection box 82 and an iron filings collection box 81 placed inside the material collection box 82. The collection trough 7 is inclined and extends to the port of the iron filings collection box 81. During installation, ensure that the inclination is such that only iron filings can pass between the lower end and the port, and the shift lever cannot pass through. This will easily ensure the separation of iron filings from the shift lever. Four support legs are fixedly installed at the bottom of the operating platform 1. A dust outlet is opened in the middle of the operating platform 1.

[0023] In summary, in actual use, the shift lever polishing device involves manually placing the shift lever to be polished at the center of the three jaws of the three-jaw pneumatic chuck 53, turning on the air pump, and using the air hose 54 to automatically retract the three-jaw pneumatic chuck to clamp the shift lever. Then, the pneumatic telescopic rod 3, through which air is supplied, drives the two polishing plates 4 to move towards the center. When the two polishing plates 4 reach a certain position, the distance sensor 9 sends a signal, the pneumatic telescopic rod 3 stops, and the polishing device 5 starts, causing the shift lever to rotate between the two polishing plates 4. The two polishing plates 4 tightly press the shift lever down, and the internal spring 42 and sponge pad 43 deform due to the pressure. The polishing paper 44 tightly wraps around the shift lever to be polished, thus achieving the polishing effect. Because the two polishing papers 44 are tightly closed, the iron filings and dust generated during polishing remain between the two polishing plates 4. After polishing is completed, the two pneumatic telescopic rods 3... When the grinding plate 4 is separated, the spring 42 and the sponge pad 43 will return to their original state, causing the iron filings and dust to fall off. The iron filings and dust fall through the dust outlet in the middle of the operating table 1 and slide down the collection groove 7 to the iron filings collection box 81 for collection. After the distance sensor 9 detects that the grinding plate has returned to its original position, the three-jaw pneumatic chuck 53 is released, and the ground shift lever will fall down along the collection groove 7 to the material collection box 82. There is a small baffle and an opening at the bottom of the collection groove 7. The ground shift lever is too large and falls unimpeded into the material collection box 82 in front. The iron filings and dust generated are small and will pass through the opening into the iron filings collection box 81. This device has a simple and reasonable structure, is convenient for maintenance and operation, has high grinding and polishing efficiency, and has fewer parts that require personnel contact, thus improving operational safety. At the same time, it solves the problems of iron filings and dust flying during the polishing process, personnel cleaning of iron filings and dust, and collection of shift levers.

[0024] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions, and alterations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
