The specific working procedure is as follows:
During working, the workpiece is placed in the moving part 2 for clamping and rotating, so that the workpiece is polished by the polishing part 3, and meanwhile, the collecting part 4 is opened to collect waste gas and scraps generated during polishing;
The workpiece is clamped on the clamping mechanism 25, the first motor 22 is turned on, the output end of the first motor 22 drives the screw rod 21 to rotate in the inner side of the machine body 1, so that the movable frame 23 is driven to move in the inner side of the machine body 1, proper adjustment work is carried out according to different lengths of the workpiece, after the workpiece is clamped, the second motor 24 is turned on, the output end of the second motor 24 drives the clamping mechanism 25 to rotate, and therefore the polishing part 3 polishes the workpiece on the clamping mechanism 25;
when the workpiece is clamped and fixed, the side surface of the workpiece is clamped or the inner side of the workpiece is clamped according to the size of the workpiece and the hardness of the material because the sizes of the workpiece are different and the hardness of the material is different, when the side surface of the workpiece is required to be clamped, the side surface of the workpiece is propped against through the three clamping plates 257, the threaded rod 253 is in threaded connection with the inner side of the clamping seat 251, the threaded rod 253 is driven to move on the clamping seat 251 through the continuous rotation knob 254 by continuously rotating the knob 254, the threaded rod 253 drives the clamping plate 257 to clamp the side surface of the workpiece through the rotation shaft 259, so that the side surface of the workpiece is clamped, and when the plastic workpiece is polished, because the material of the plastic workpiece is softer, if the side surface of the plastic workpiece is clamped, when the plastic workpiece is in contact polishing with the polishing component 3, the plastic workpiece is easy to deform, so that polishing deviation is caused for polishing the plastic workpiece, when the plastic workpiece is required to be clamped, as the rods of the speed-regulating rotary handle of the electric vehicle are arranged in a hollow mode, three clamping blocks 258 are supported and propped against the inner wall of the plastic workpiece, the clamping blocks 258 are driven by stretching of the first springs 256, the clamping blocks 258 are propped against the inner wall of the plastic workpiece, meanwhile, the threaded rods 253 are rotated, so that the threaded rods 253 drive the clamping blocks 258 to be tightly attached to the inner surface of the plastic workpiece, accurate positioning is realized, the inner wall of the hollow shaft is a relatively stable supporting surface, the workpiece can be better fixed, displacement and shaking in the processing process are reduced, and the processing precision is improved, the polishing part 3 is convenient for polishing the side surface of the plastic workpiece;

When the filter mechanism 48 stops working, the square frame 44 is reset through the stretching of the second spring 46, and drives the ejector rod 471 to move towards the mesh of the screen plate 42, so that the ejector rod 471 drives the ejector pin 475 to eject the scraps clamped at the mesh, meanwhile, when the extrusion force between the ejector pin 475 and the scraps clamped in the mesh is larger than the stretching force of the third spring 476, the slide block 473 drives the ejector pin 475 to move in the notch 472 through the connecting shaft 474, so that the extrusion force between the ejector pin 475 and the scraps clamped in the mesh of the screen plate 42 is prevented from being too large, the ejector pin 475 is prevented from being extruded and damaged, and meanwhile, the inner side of the mesh of the screen plate 42 is rubbed and damaged, so that the aperture of the mesh is enlarged;
By opening the air suction machine 484, the waste gas and the waste scraps generated during the polishing of the workpiece are sucked into the collecting tank 41 through the suction machine 484, meanwhile, the waste gas entering into the collecting tank 41 continuously enters into the filtering pipe 481 through the through holes 482 through the air suction machine 484, so that the waste gas is discharged through the carbon powder box 485 through the air outlet plate 483, the waste gas generated during the polishing is prevented from being directly discharged, the concentration of pollutants such as particles and VOCs in the waste gas can be increased, the air quality is reduced, the suction force generated during the operation of the air suction machine 484 is utilized, the contact assembly 489 can move on the fixed rod 481, the contact assembly 489 can move the inner wall of the filtering pipe 481, and meanwhile, when the contact assembly 489 is reset through the movement of the fourth spring 488, the contact assembly 489 and the buffer assembly 487 are contacted and impacted, and therefore the contact assembly 489 can perform the buffer operation;
When the air suction machine 484 works, the contact frame 4891 drives the scraping plate 4893 to move on the fixed rod 4810 through the abdication hole 4812, meanwhile, the scraping plate 4893 can move and clean the inner wall of the filter tube 481, when the air suction machine 484 stops working after the waste gas collection work is finished, the contact frame 4891 can be driven by the reset of the fourth spring 488, the scraping plate 4893 can carry out secondary cleaning and rubbing work on the inner side of the filter tube 481, so that the waste gas is prevented from passing through the filter tube 481 for a long time, a large amount of smoke dust impurities can be remained on the inner side of the filter tube 481, and the inner wall of the filter tube 481 can be corroded for a long time;
When the aspirator 484 stops working, the contact frame 4891 is pulled through the reset of the fourth spring 488, thereby the contact frame 4891 moves towards the connecting frame 4871, thereby when the fourth spring 488 drives the contact frame 4891 to move towards the connecting frame 4871 through the rubber block 4873 arranged on the buffer plate 4872, the impact force between the contact frame 4891 and the connecting frame 4871 is avoided to be overlarge, thereby the side surface of the contact frame 4891 is damaged, and meanwhile, when the contact frame 4891 and the rubber block 4873 are contacted and impacted, the dust impurities scraped on the scraping plate 4893 can be shaken off through the vibration generated during the impact, so that the residual dust impurities on the scraping plate 4893 are avoided after the inner side of the filter tube 481 is cleaned by the scraping plate 4893.
