[0025] Embodiment

[0026] As Figures 1-4 shown, the rotary lifting mechanism 2 includes a drive shaft 201 passing through the top of the frame body 1. A first gear 206 is sleeved on the surface of the drive shaft 201 below the top wall of the frame body 1. A second gear 209 is provided on one side of the first gear 206. A movable plate 210 is provided at the lower left of the first gear 206. A connecting column 211 is provided on one side of the movable plate 210. A partition board 202 is provided on the side wall of the frame body 1, and the two side walls of the frame body 1 are connected by the partition board 202. A first drive motor 203 is provided on the side wall of the frame body 1 above the movable plate 210. A fastening block 204 is threadedly connected to the top of the drive shaft 201. A stop block 205 is provided on the surface of the drive shaft 201 at the top of the frame body 1. A limit block 207 is provided on the surface of the drive shaft 201 directly below the first gear 206. A second drive motor 208 is provided on the top of the partition board 202.

[0027] It should be noted that in this embodiment, when polishing the plastic part, first, the plastic part is sleeved on the top of the driving shaft 201, and then the fastening block 204 is tightened. The fastening block 204 and the stopper 205 fix the plastic part. Subsequently, the first driving motor 203 and the second driving motor 208 are started. When the second driving motor 208 operates, it drives the movable plate 210 to rotate. The movable plate 210 drives the limiting block 207 to move through the connecting column 211, and further drives the driving shaft 201 to move. The reciprocating motion of the second driving motor 208 drives the driving shaft 201 to lift and lower. When the first driving motor 203 operates, it drives the first gear 206 to rotate through the second gear 209, thereby further driving the driving shaft 201 to rotate, so that the driving shaft 201 rotates while lifting and lowering, which is convenient for comprehensively polishing the plastic part.

[0028] As Figure 1 , 2 , as shown in Figure 5, the surface treatment mechanism 3 includes a first baffle 301 installed on the top of the frame body 1. A second baffle 302 is provided on the top of the frame body 1. A guide rail 303 is provided between the first baffle 301 and the second baffle 302. A third driving motor 304 is provided on one side of the first baffle 301. A sliding plate 305 is provided on the top of the guide rail 303. A polishing machine 306 is provided on the top of the sliding plate 305. Guide wheels 307 are provided at the four corners of the sliding plate 305. A threaded rod 308 is threadedly connected to the bottom of the sliding plate 305, and one end of the threaded rod 308 is axially connected to the third driving motor 304.

[0029] It should be noted that in this embodiment, a guide rail 303 is provided between the first baffle 301 and the second baffle 302. The two ends of the guide rail 303 are slidably connected to the guide wheels 307 at the four corners of the sliding plate 305. When the third driving motor 304 operates, the axially connected threaded rod 308 rotates. The threaded rod 308 is threadedly connected to the bottom of the sliding plate 305. When the threaded rod 308 rotates, due to the limiting effect of the guide wheels 307 and the guide rail 303, the sliding plate 305 can only move along the guide rail 303, so as to adjust the distance between the polishing machine 306 and the plastic part as needed. After the polishing machine 306 is started, the polishing machine 306 can perform a comprehensive polishing treatment on the engineering plastic part within a certain range.

[0030] The working principle of the present utility model:

[0031] Referring to the attached drawings of the specification Figures 1-5When polishing a plastic part, first, the plastic part is sleeved on the top of the drive shaft 201, and then the fastening block 204 is tightened. The fastening block 204 and the stop block 205 fix the plastic part. Subsequently, the first drive motor 203 and the second drive motor 208 are started. When the second drive motor 208 operates, it drives the movable plate 210 to rotate. The movable plate 210 drives the limit block 207 to move through the connecting column 211, thereby driving the drive shaft 201 to move. The reciprocating movement of the second drive motor 208 drives the drive shaft 201 to lift and lower. When the first drive motor 203 operates, it drives the first gear 206 to rotate through the second gear 209, thereby further driving the drive shaft 201 to rotate, enabling the drive shaft 201 to rotate while lifting and lowering, which is convenient for the all-round grinding of the plastic part;

[0032] A guide rail 303 is provided between the first baffle 301 and the second baffle 302. The two ends of the guide rail 303 are slidably connected to the guide wheels 307 at the four corners of the sliding plate 305. When the third drive motor 304 operates, the axially connected threaded rod 308 rotates. The bottom of the sliding plate 305 is threadedly connected to the threaded rod 308. When the threaded rod 308 rotates, due to the limiting effect of the guide wheels 307 and the guide rail 303, the sliding plate 305 can only move along the guide rail 303, thereby adjusting the distance between the polishing machine 306 and the plastic part as needed. After the polishing machine 306 is started, the polishing machine 306 can perform a comprehensive polishing treatment on the engineering plastic part within a certain range.

[0033] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention.
