Description

Technical Field

[0001] The utility model relates to the technical field of automobile parts processing equipment, in particular to a welding and grinding device for automobile parts processing. Background Art

[0002] In order to save manufacturing costs, many auto parts are assembled by welding. After the auto parts are welded, the welding positions of the parts are polished to make the parts more beautiful.

[0003] The currently published patent: CN216463725U, discloses a grinding device for automobile parts processing. According to the thickness of the mold, the fastening bolts are tightened to fix the mold, and then the first electric telescopic rod is started, and the grinding stone moves downward. When the bottom of the grinding stone abuts against the upper end surface of the mold, the mold begins to be polished. At the same time, the push rod can be pushed to move the position of the movable table to perform all-round grinding of the mold on the workbench. The utility model can adjust the clamping and fixing according to the size of the automobile parts, improve the grinding quality of the automobile parts, and facilitate the grinding of different parts of the mold, thereby improving work efficiency.

[0004] Based on the above search, it was found that the above patent has the following problems when in use: when the grinding device is grinding parts, it can only adjust the position of the parts, thereby facilitating the grinding of different parts, but it cannot adjust the grinding surface of the parts. Since the parts may have multiple surfaces with welding points that need to be ground, at this time, the staff needs to finish grinding one side, disassemble it, and then re-clamp it before grinding the other surfaces. It is impossible to directly grind multiple surfaces of the parts, which not only reduces the grinding efficiency of the parts, but also increases the labor intensity of the staff.

[0025] After the staff places the parts on the top of the rotating plate 7, the servo motor 12 is started. The output end of the servo motor 12 rotates to drive the bidirectional threaded rod 11 to rotate. The rotation of the bidirectional threaded rod 11 can drive the two sliders 9 to slide relative to each other. The two sliders 9 slide relative to each other and drive the two fixed clamps 10 to slide relative to each other and clamp the parts on the surface, thereby fixing the parts on the top of the rotating plate 7. After the staff starts the hydraulic telescopic rod 2, the output shaft of the hydraulic telescopic rod 2 moves downward to drive the grinding motor 3 and the grinding disc 4 to move downward at the same time, and make the grinding disc 4 contact with the welding position of the parts. After the staff starts the grinding motor 3, the output end of the grinding motor 3 rotates to drive the grinding disc 4 to rotate to grind the welding points of the parts.

[0027] When the staff needs to grind different surfaces of the component, the staff can start the drive motor 15. The output end of the drive motor 15 rotates to drive the second sprocket 16 to rotate. The second sprocket 16 rotates and drives the first sprocket 13 and the rotating shaft 6 on the right side to rotate through the chain 14. The rotation of the rotating shaft 6 can drive the rotating plate 7 and the top component to rotate at the same time, thereby rotating the surface of the component to be polished to the upper position. The polishing motor 3 is a new type of motor with a brake from Panasonic. It adds a brake on the basis of an ordinary servo motor, which can achieve more efficient control and safer operation. The brake can maintain the position of the motor through braking torque when the polishing motor 3 stops running, thereby keeping the rotating plate 7 and the component in different positions. At this time, the polishing disc 4 can polish the welding point of the surface again. After the staff finishes polishing one side, they can directly adjust the angle to polish the other side. Therefore, multiple surfaces of the component can be polished directly, which not only improves the polishing efficiency of the component, but also reduces the labor intensity of the staff.

[0028] Working principle: This welding and grinding device for automobile parts processing, after the staff puts the parts on the top of the rotating plate 7, by starting the servo motor 12, the output end of the servo motor 12 rotates to drive the bidirectional threaded rod 11 to rotate, and the rotation of the bidirectional threaded rod 11 can drive the two sliders 9 to slide relative to each other, and the two sliders 9 slide relative to each other and drive the two fixed clamps 10 to slide relative to each other and clamp the parts on the surface, thereby fixing the parts on the top of the rotating plate 7. After the staff starts the hydraulic telescopic rod 2, the output shaft of the hydraulic telescopic rod 2 moves downward to drive the grinding motor 3 and the grinding disc 4 to move downward at the same time, and make the grinding disc 4 and the parts aligned with each other. The welding position of the parts is in contact. After the staff starts the grinding motor 3, the output end of the grinding motor 3 rotates to drive the grinding disc 4 to rotate and grind the welding points of the parts. The staff can start the driving motor 15. The output end of the driving motor 15 rotates to drive the second sprocket 16 to rotate. The second sprocket 16 rotates and drives the first sprocket 13 and the rotating shaft 6 on the right side to rotate through the chain 14. The rotation of the rotating shaft 6 can drive the rotating plate 7 and the top parts to rotate at the same time, and then rotate the surface of the part to be polished to the upper position, and the grinding disc 4 can grind the welding points on the surface again, and directly grind multiple surfaces of the parts.

Various changes can be made within the scope of knowledge possessed by ordinary technicians in the technical field without departing from the purpose of the present invention.
