It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0022] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0023] Embodiment 1, as Figure 1-Figure 4As shown, the utility model provides a screw polishing machine, including: a frame 1, a second motor 4 is fixedly connected to the outer surface of the frame 1, an output end of the second motor 4 slides through the frame 1 and extends to the inner side, a second rotating shaft 5 is fixedly connected to the output end of the second motor 4, and an eccentric wheel 6 is symmetrically fixedly connected to the outer surface of the second rotating shaft 5; a supporting assembly 2, the supporting assembly 2 is fixedly connected to the inner surface of the frame 1, and the supporting assembly 2 includes a fixed plate 201; a polishing assembly 3, the polishing assembly 3 is located on the upper side of the fixed plate 201, and the polishing assembly 3 includes a bracket 301, a push rod 302 is symmetrically fixedly connected to the bottom of the bracket 301, and a through hole is symmetrically opened on the top of the fixed plate 201, a bearing 202 is fixedly connected to the inner surface of the through hole, and the outer surface of the push rod 302 is in contact with the inner surface of the bearing 202 The lower end surface of the push rod 302 is located at the lower side of the fixed plate 201, and the push rod 302 cooperates with the position of the eccentric wheel 6. The inner surface of the bracket 301 is rotatably connected to the support shaft 306, and the end surface of the support shaft 306 is fixedly connected to the roller 307. The outer surface of the roller 307 is provided with a cover plate 308. The inner surface of the other side of the bracket 301 is rotatably connected to the drive shaft 309, and the drive shaft 309 is fixedly connected to the roller 307. The bottom of the bracket 301 is fixedly connected to the first motor 303, and the output end of the first motor 303 is fixedly connected to the first rotating shaft 304. The outer surface of the first rotating shaft 304 is fixedly connected to the first pulley 305, and the outer surface of the drive shaft 309 is fixedly connected to the second pulley 310. A belt 311 is sleeved between the outer surfaces of the first pulley 305 and the second pulley 310.

[0024] The effect achieved by the entire embodiment 1 is that when the screw is polished, the cover plate 308 is opened to put the screw into the drum 307. After the feeding is completed and the cover plate 308 is closed, the first motor 303 is started to drive the first rotating shaft 304 to rotate. When the first rotating shaft 304 rotates, the driving shaft 309 can be driven to rotate along through the connection between the first pulley 305, the belt 311 and the second pulley 310. The rotation of the driving shaft 309 drives the drum 307 to rotate. During the rotation of the drum 307, friction and collision occur between the screw and the abrasive, thereby The convex edges and burrs on the surface of the screw are removed to achieve a polishing effect. While the roller 307 rotates for polishing, the support plate 205 at the bottom provides support for the bracket 301. The second motor 4 is started to drive the eccentric wheel 6 to rotate through the connection with the second rotating shaft 5. When the eccentric wheel 6 rotates, the eccentric wheel 6 contacts the push rod 302 at the bottom. The eccentric wheel 6 can repeatedly contact the push rod 302 to push the push rod 302 upward. The push rod 302 can push the bracket 301 to move upward. Under the high-speed operation of the eccentric wheel 6, the bracket 301 can repeatedly jump up and down.

[0025] Embodiment 2, as Figure 1-Figure 4As shown, two groups of dampers 203 are symmetrically fixedly connected to the top of the fixed plate 201, and springs 204 are sleeved on the outer surfaces of multiple dampers 203. A supporting plate 205 is fixedly connected between the upper end surfaces of the two groups of dampers 203, and the top of the supporting plate 205 is in contact with the bottom of the bracket 301.

[0026] The effect achieved by the entire embodiment 2 is that when the bracket 301 falls freely during the rotation of the eccentric wheel 6, the damper 203 and the spring 204 can play a role of buffering support, thereby avoiding damage during the operation of the polishing machine and improving the service life of the polishing machine.

[0027] Working principle: When polishing the screws, open the cover plate 308 and put the screws into the drum 307. After the feeding is completed and the cover plate 308 is closed, start the first motor 303 to drive the first rotating shaft 304 to rotate. When the first rotating shaft 304 rotates, the driving shaft 309 can be driven to rotate along through the connection of the first pulley 305, the belt 311 and the second pulley 310. The rotation of the driving shaft 309 drives the drum 307 to rotate. During the rotation of the drum 307, friction and collision occur between the screw and the abrasive, thereby removing the convex edges and burrs on the surface of the screw to achieve the polishing effect. While the drum 307 rotates for polishing, the support plate 205 at the bottom provides support for the bracket 301, and the second motor 4 is started to drive the eccentric wheel 6 to rotate through the connection of the second rotating shaft 5. When the eccentric wheel 6 rotates, the eccentric wheel 6 contacts the push rod 302 at the bottom, and the eccentric wheel 6 can repeatedly contact with the push rod 30 2 contact pushes the push rod 302 upward, and the push rod 302 can push the bracket 301 to move upward. Under the high-speed operation of the eccentric wheel 6, the bracket 301 can jump up and down repeatedly. When the roller 307 inside the bracket 301 rotates, the bracket 301 jumps up and down at a high frequency, which can make the screws inside the roller 307 jump up and down repeatedly, so that the screws accumulated at the bottom and corners are shaken out, and the screws in the roller 307 can be evenly contacted with the abrasive on the inner wall of the roller 307 to complete polishing, thereby improving the polishing quality of the polishing machine for the screws. The support plate 205 is used to provide a support for the bottom of the bracket 301. When the bracket 301 falls freely during the rotation of the eccentric wheel 6, the damper 203 and the spring 204 can be used in combination to play a role of buffering support, thereby reducing the impact force caused by the bracket 301 falling, avoiding damage during the operation of the polishing machine, and improving the service life of the polishing machine.
