DETAILED DESCRIPTION

[0016] In order to more clearly understand the above-mentioned objects, features and advantages of the present invention, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0017] 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 different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0018] like Figure 1 - Figure 7The polishing equipment for automobile parts shown in the figure includes a main frame 1, a base 2 is arranged on the top of the main frame 1, a workbench 3 is rotatably arranged above the base 2, a motor is arranged inside the main frame 1, the output end of the motor passes through the base 2 and is connected to the workbench 3, a ring-shaped lifting plate 13 is arranged on the surface of the base 2, an opening is opened at the front end of the lifting plate 13, and an arc-shaped edge 14 is arranged on the end face of the opening, four rectangular plates 15 are evenly arranged on the upper surface of the workbench 3, a placement plate 16 is arranged above the rectangular plate 15, a through hole is arranged in the middle of the placement plate 16 and the rectangular plate 15, an outward expansion mechanism 17 is arranged in the through hole, a cylindrical member 34 is placed above the placement plate 16, a cylinder 4 is arranged above the main frame 1 and on one side of the base 2, a connecting plate 5 is arranged at the output end of the cylinder 4, a disc 6 is arranged at the end of the connecting plate 5, and the disc 6 A polishing mechanism 12 is provided inside, which is connected to the workbench 3 through a motor, so that the workbench 3 can rotate, and the cylindrical parts 34 can be moved one by one to the bottom of the polishing mechanism 12, and then the polishing mechanism 12 is lifted and lowered by the cylinder 4, so that the surface of the cylindrical parts 34 can be polished one by one, and continuous polishing work is achieved, thereby improving work quality and work efficiency. At the same time, with the cooperation of the expansion mechanism 17 and the lifting plate 13, the expansion mechanism 17 can center and clamp the cylindrical part 34. When the polishing mechanism 12 polishes the cylindrical part 34, the cylindrical part 34 can be stably installed on the surface of the workbench 3. When the cylindrical part 34 is above the opening, the expansion mechanism 17 will not clamp the cylindrical part 34. At this time, the staff can disassemble and install the cylindrical part 34 at will, further improving work efficiency and reducing the workload of the staff.

[0019] The polishing mechanism 12 includes three polishing rollers 8, which are evenly surrounded by the surface of one of the cylindrical parts 34. A driven gear 11 is fixedly arranged on the top of the polishing roller 8, and a driving gear 10 is meshed and installed between the three driven gears 11. An inner ring gear 9 is arranged on the inner wall of the disc 6, and the surface of the driven gear 11 is meshed with the inner ring gear 9. A stepper motor 7 is arranged above the disc 6, and the output end of the stepper motor 7 is connected to the driving gear 10. The stepper motor 7 can drive the driving gear 10 to rotate. Under the cooperation between the driving gear 10, the driven gear 11 and the inner ring gear 9, the driven gear 11 can rotate between the inner ring gear 9 and the driving gear 10, so that the polishing roller 8 will rotate on the surface of the cylindrical part 34, thereby realizing the polishing operation of the cylindrical part 34.

[0020] The external expansion mechanism 17 includes four expansion plates 18, a slide plate 19 is fixedly installed at the bottom of the expansion plate 18, a first rack 23 is arranged at the bottom of the slide plate 19, four semicircular plates 24 are evenly arranged inside the workbench 3, the four semicircular plates 24 are respectively installed under the four slide plates 19, a second rack 25 is arranged on the surface of the semicircular plate 24, the second rack 25 is meshed with the first rack 23, a convex block 26 is arranged under the semicircular plate 24, and a movable rod 23 is movably arranged between the four semicircular plates 24 8. Bosses 29 are provided at the four end corners of the movable rod 28. A connecting rod 27 is installed between the boss 29 and the convex block 26 through a rotating shaft. When the position of the movable rod 28 moves up, the boss 29 is lifted. At this time, the connecting rod 27 has the effect of pulling the convex block 26 upward, so that the semicircular plate 24 will flip over. At the same time, the second rack 25 on the surface of the semicircular plate 24 can drive the first rack 23 to move, and the slide plate 19 and the expansion plate 18 will expand outward, so that the inner wall of the cylindrical part 34 can be centered and clamped.

[0021] A lifting rod 31 is fixedly installed at the bottom of the movable rod 28, and a semicircular block 32 is arranged at the bottom end of the lifting rod 31. The lifting rod 31 corresponds to the lifting plate 13, and a spring 30 is arranged on the surface of the movable rod 28. When the workbench 3 rotates, the outward expansion mechanism 17 will also rotate with the workbench 3. When the semicircular block 32 at the bottom of the lifting rod 31 contacts the arc-shaped edge 14, the arc-shaped edge 14 has a certain squeezing effect on the semicircular block 32, so that the position of the lifting rod 31 moves upward. At this time, the lifting rod 31 drives the position of the movable rod 28 to move upward, so that the expansion plate 18 can expand outward and clamp the cylindrical part 34. When the lifting rod 31 is at the opening, under the action of the elastic force of the spring 30 and its own gravity, the position of the lifting rod 31 and the movable rod 28 moves downward, so that the expansion plate 18 shrinks inward and the clamping force on the cylindrical part 34 is reduced.

[0022] Four matching grooves 33 are evenly arranged on the inner wall of the placement plate 16, and the matching grooves 33 correspond to the expansion plate 18. When the expansion mechanism 17 expands outward, the expansion plate 18 can be displaced to the inside of the matching grooves 33, thereby realizing the positioning of the cylindrical part 34. At the same time, the matching grooves 33 also prevent the position of the expansion plate 18 from shifting, thereby improving the stability of the expansion plate 18 when in use.

[0023] Four shrinkage grooves 21 are evenly arranged inside the rectangular plate 15, and the surface of the slide plate 19 is movably clamped in the shrinkage groove 21. A slide groove 22 is provided on the inner wall of the shrinkage groove 21. A limit strip 20 is arranged on the surface of the slide plate 19. The surface of the limit strip 20 is slidably installed in the slide groove 22, so that the slide plate 19 can slide inside the shrinkage groove 21, ensuring the stability of the expansion plate 18 clamping the inner wall of the cylindrical member 34. At the same time, under the action of the limit strip 20 and the slide groove 22, the stability of the slide plate 19 during movement can be further guaranteed.

[0024] Arc plates 35 are provided on both sides of the base 2 and the workbench 3, and a top plate 36 is provided on the top of the arc plate 35. The top plate 36 is installed above the cylindrical member 34. When the cylindrical member 34 rotates under the top plate 36, the outward expansion mechanism 17 has a positioning function for the cylindrical member 34. The top plate 36 can limit the position of the cylindrical member 34 to prevent the cylindrical member 34 from moving upward, thereby ensuring the positioning of the cylindrical member 34 and ensuring the polishing effect of the subsequent polishing mechanism 12 on the surface of the cylindrical member 34.

[0025] The arc plates 35 are located on both sides of the opening, and the disc 6 is located on the opposite side of the opening, so that the top plate 36 can limit the cylindrical parts 34 on both sides of the opening, while the cylindrical parts 34 above the opening and below the disc 6 will not be restricted by the top plate 36. Therefore, when the cylindrical parts 34 are above the opening, the staff can disassemble the cylindrical parts 34 at will.

[0026] Working principle: First, the output end of the motor is connected to the workbench 3. After the staff places the cylindrical part 34 on the surface of the placement plate 16, the workbench 3 rotates. When the semicircular block 32 at the bottom of the lifting rod 31 contacts the arc edge 14, the arc edge 14 has a certain squeezing effect on the semicircular block 32, so that the position of the lifting rod 31 moves upward. At this time, the lifting rod 31 drives the position of the movable rod 28 to move upward, so that the expansion plate 18 can expand outward and clamp the cylindrical part 34. Then, when the cylindrical part 34 rotates to the bottom of the polishing mechanism 12, the cylinder 4 lowers the polishing mechanism 12, and the three polishing rollers 8 are evenly surrounded on the surface of one of the cylindrical parts 34. The stepping motor 7 can drive the driving gear 10 to rotate. With the cooperation between the driven gear 11 and the inner ring gear 9, the driven gear 11 can rotate between the inner ring gear 9 and the driving gear 10, so that the polishing roller 8 can rotate on the surface of the cylindrical part 34, thereby realizing the polishing operation of the cylindrical part 34, and then continue to rotate the workbench 3. When the cylindrical part 34 is above the opening, under the elastic force of the spring 30 and its own gravity, the position of the lifting rod 31 and the movable rod 28 moves downward, so that the expansion plate 18 shrinks inward, and the clamping force on the cylindrical part 34 is reduced. At this time, the staff can disassemble and install the cylindrical part 34 at will. The device can polish the surface of the cylindrical part 34 one by one, realize continuous polishing work, improve work quality and work efficiency, and reduce the workload of the staff.
