Description

Technical Field

[0001] This utility model relates to the field of polishing and grinding technology for automotive parts, specifically to a polishing and grinding device for automotive parts. Background Technology

[0002] Automotive parts polishing and grinding equipment is mainly used to treat the surface of automotive parts. Through polishing and grinding, burrs, scratches and defects on the surface of automotive parts can be removed, making the surface smoother and more delicate, and improving the overall aesthetics.

[0003] Before polishing, there will be residues on the car parts, including dust. These residues will affect the polishing effect. During the polishing process, friction between the polishing device and the surface of the parts will generate some frictional heat and wear. Metal powder and other residues produced by the wear of the polishing head will adhere to the parts. If they are not cleaned in time, they will affect the subsequent coating effect or cause problems such as spots and scratches on the surface of the parts.

Detailed Implementation

[0017] To further understand the features, technical means, and specific objectives and functions achieved by this utility model, the following detailed description of this utility model is provided in conjunction with the accompanying drawings and specific embodiments.

[0018] Reference Figures 1-3 A polishing and grinding device for automotive parts includes a mounting frame 101, on which a polishing and grinding device 103 is mounted. A worktable 102 and a mounting frame 104 are mounted on the top wall of the mounting frame 101. A clamping mechanism 200 and a cleaning mechanism 400 are mounted on the worktable 102. The clamping mechanism 200 and the cleaning mechanism 400 are connected by a connecting mechanism 300.

[0019] Mounting bracket 101 provides support, polishing device 103 polishes automotive parts, clamping mechanism 200 clamps and fixes automotive parts to support polishing and improve polishing efficiency, and cleaning mechanism 400 cleans the surface of automotive parts before and after clamping and fixing them to improve polishing effect.

[0020] Reference Figures 1-3 The clamping mechanism 200 includes a motor 201, a bidirectional lead screw 202, a guide rod 203, a reciprocating block 204, and a clamping plate 205. The motor 201 is mounted on the mounting frame 101. The output end of the motor 201 passes through the side wall of the mounting frame 104 and connects to the bidirectional lead screw 202. The other end of the bidirectional lead screw 202 is rotatably engaged with the inner wall of the mounting frame 104. The guide rod 203 is rotatably provided on the side of the worktable 102 away from the bidirectional lead screw 202. The reciprocating block 204 is symmetrically slidably provided on the bidirectional lead screw 202 and the guide rod 203. The reciprocating block 204 is slidably disposed inside the mounting frame 104. The reciprocating block 204 is provided with a thread that engages with the bidirectional lead screw 202. The clamping plate 205 is mounted on the reciprocating block 204. The surface of the clamping plate 205 that contacts the parts is provided with a rubber pad.

[0021] The starter motor 201 drives the bidirectional lead screw 202 to rotate. The bidirectional lead screw 202 cooperates with the reciprocating block 204 to realize the relative or opposite movement of the reciprocating block 204, thereby realizing the clamping plate 205 to clamp, fix and unlock the automotive parts.

[0022] Reference Figures 2-3 The connecting mechanism 300 includes a synchronous belt 301, a rotating rod 302, and a fixing block 303. The mounting frame 101 is symmetrically provided with fixing blocks 303. The rotating rod 302 is rotatably provided between the fixing blocks 303. The side wall of the rotating rod 302 and the side wall of the bidirectional lead screw 202 are both provided with pulleys. The synchronous belt 301 is sleeved between the pulleys.

[0023] The rotation of the bidirectional lead screw 202 drives the synchronous belt 301 to rotate, the rotating rod 302 drives the rotating rod 302 to rotate, and the rotating rod 302 drives the cleaning mechanism 400 to rotate.

[0024] Reference Figure 3 The cleaning mechanism 400 includes a cleaning brush 401, a mounting plate 402, a support column 403, a moving block 404, a return spring 405, a connecting rope 406, a rotating shaft 407, and a guide rail 408. The guide rail 408 is provided on one side of the workbench 102 on the mounting frame 101. The moving block 404 is slidably mounted on the guide rail 408. The support column 403 is provided on the side wall of the moving block 404, and the mounting plate 402 is mounted on the side wall of the support column 403. A cleaning brush 401 is installed on the side of the mounting plate 402 near the workbench 102. The two ends of the return spring 405 are respectively connected to the side wall of the moving block 404 and the side wall of the guide rail 408. The guide rail 408 is rotatably provided with a rotating shaft 407 at the end away from the return spring 405. One end of the rotating shaft 407 passes through the side wall of the fixed block 303 and is connected to the rotating rod 302. One end of the connecting rope 406 is wrapped around the outer wall of the rotating shaft 407, and the other end of the connecting rope 406 is connected to the side wall of the moving block 404.

[0025] The rotating rod 302 drives the rotating shaft 407 to rotate. When the bidirectional lead screw 202 rotates and drives the reciprocating block 204 to move relative to each other and clamp and fix the car parts, the connecting rope 406 pulls the moving block 404 away from the return spring 405. Since the cleaning brush 401 is made of elastic material, it can clean the car parts. After clamping and fixing, the cleaning brush 401 has finished cleaning the car parts and continues to slide along the direction to a certain distance before stopping. When the bidirectional lead screw 202 rotates and drives the reciprocating block 204 to unlock the car parts, the return spring 405 drives the moving block 404 and the cleaning brush 401 to reset. The return spring 405 is in a tensioned state. During the reset movement, the cleaning brush 401 can further clean the polished car parts and remove the metal powder and other residues generated by the wear of the grinding head, making them fall off the parts, thereby improving the polishing effect.

[0026] Working principle: The automotive parts to be polished are placed on the worktable 102. The motor 201 is started, driving the bidirectional lead screw 202 to rotate. Through the cooperation of the bidirectional lead screw 202 and the reciprocating block 204, the reciprocating block 204 moves relative to or in opposite directions, realizing the clamping plate 205 clamping, fixing, and unlocking the automotive parts. The rotation of the bidirectional lead screw 202 drives the synchronous belt 301 to rotate, the rotating rod 302 drives the rotating shaft 407 to rotate. When the bidirectional lead screw 202 rotates and drives the reciprocating block 204 to move relative to and clamp the automotive parts, the connecting rope 406 pulls the moving block 404 away from the return spring 405. As the cleaning brush 401 is made of elastic material, it can clean the automotive parts. After clamping and fixing, the cleaning brush 401 has finished cleaning the automotive parts and continues to slide along the direction to a certain distance before stopping. When the bidirectional lead screw 202 rotates and drives the reciprocating block 204 to unlock the automotive parts, the reset spring 405 drives the moving block 404 and the cleaning brush 401 to reset. The reset spring 405 is in a tensioned state. During the reset movement, the cleaning brush 401 can further clean the polished automotive parts, and can clean the metal powder and other residues generated by the wear of the grinding head, so that they are removed from the parts, thereby improving the polishing effect.

It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model.
