Description

Technical Field

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

[0002] In the manufacturing sector, many mechanical parts must undergo meticulous grinding and polishing after production to remove burrs and other irregular protrusions from their surfaces. This process is not only for aesthetics but, more importantly, to ensure the smoothness of the surface, thereby enhancing the mechanical adhesion of coatings. Grinding and polishing equipment is equipped with clamping components to hold the mechanical parts in place. When grinding round mechanical parts of different sizes, it is usually necessary to replace the clamping components with different specifications. Existing grinding and polishing equipment typically requires disassembling the clamping components on the lifting platform and then installing the required ones, making the entire replacement operation complex and reducing the efficiency of grinding. Secondly, existing grinding and polishing equipment lacks protective components during use, allowing waste chips generated during grinding to easily fly around, posing a safety hazard and potential injury to workers.

[0028] Please see Figure 1-5 A grinding and polishing device for machining mechanical parts includes a lifting platform 1, a clamping platform 2 rotatably mounted on the lifting platform 1, a rotary motor 3 fixedly mounted at the lower end of the lifting platform 1, the drive end of the rotary motor 3 passing through the lifting platform 1 and fixedly connected to the clamping platform 2, the clamping platform 2 being cross-shaped, and four clamping components mounted on the clamping platform 2, each clamping component including two clamping slots 4 mounted on the clamping platform 2, a bidirectional lead screw 5 rotatably mounted in the two clamping slots 4, a clamping seat 6 movably mounted in each clamping slot 4, the clamping seat 6 being threadedly connected to the bidirectional lead screw 5, a clamping plate 7 fixedly mounted at the upper end of the clamping seat 6 passing through the clamping slot 4, a clamping motor 8 fixedly connected at one end of the bidirectional lead screw 5 passing through the clamping platform 2, the clamping motor 8 being fixedly mounted on the side of the clamping platform 2, a protective shell 9 movably mounted on the outside of the lifting platform 1, a grinding motor 10 mounted inside the protective shell 9, and a grinding and polishing disc 11 mounted at the drive end of the grinding motor 10.

[0029] In this embodiment, when it is necessary to clamp and fix the circular mechanical parts to be polished, the rotary motor 3 is started according to the size of the mechanical parts. The rotary motor 3 drives the clamping table 2 to rotate, and the clamping table 2 drives the four clamping components to rotate. Since the two clamping plates 7 on each clamping component are of different sizes, the two required clamping plates 7 are rotated to the lower end of the polishing disc 11. The mechanical parts are placed on the clamping table 2 between the two clamping plates 7. The clamping motor 8 is started, and the clamping motor 8 drives the bidirectional lead screw 5 to rotate. Since the bidirectional lead screw 5 has two threaded areas 27 with opposite directions, the two clamping seats 6 move in adjacent directions. The clamping seats 6 drive the clamping plates 7 to move, thereby clamping and fixing the mechanical parts.

[0030] Please see Figures 1-5 As one method of protecting workers: a protective door 12 is movably provided on one side of the protective shell 9; a limiting groove 13 is provided inside the protective shell 9; a limiting strip 14 is movably provided in the limiting groove 13; the upper end of the protective door 12 extends into the limiting groove 13 and is fixedly connected to the limiting strip 14; a toothed belt 15 is fixedly provided at the upper end of the limiting strip 14; a protective motor 16 is fixedly provided at the upper end of the protective shell 9; a rotating gear 17 is fixedly provided at the drive end of the protective motor 16; the rotating gear 17 meshes with the toothed belt 15; a storage slot 18 that cooperates with the protective door 12 is provided inside the protective shell 9; and a workbench 19 is fixedly provided at the lower end of the protective shell 9. The system includes a drive chamber 20 and a regulating motor 21 fixedly mounted on one side of the worktable 19. The driving end of the regulating motor 21 extends into the drive chamber 20 and is fixedly mounted with a rotating rod 22. The rotating rod 22 is rotatably connected to the drive chamber 20. Two driving bevel gears 23 are fixedly mounted on the rotating rod 22. The protective shell 9 has two lifting grooves 24. Each lifting groove 24 is rotatably mounted with a screw 25. The screw 25 is threadedly connected to the lifting platform 1. The lower end of the screw 25 extends into the drive chamber 20 and is fixedly mounted with a driven bevel gear 26. The driven bevel gear 26 meshes with the driving bevel gear 23.

[0031] More specifically, when the protective door 12 needs to be closed, the protective motor 16 is activated, which drives the rotating gear 17 to rotate. Since the rotating gear 17 is meshed with the toothed belt 15, the toothed belt 15 drives the limiting strip 14 to move along the limiting groove 13. The limiting strip 14 drives the protective door 12 to move, thus closing the protective door 12. The adjusting motor 21 is activated, which drives the rotating rod 22 to rotate. The rotating rod 22 drives the two driving bevel gears 23 to rotate. The driving bevel gears 23 drive the driven bevel gear 26 to rotate. The driven bevel gear 26 drives the screw 25 to rotate. Since the screw 25 is threadedly connected to the lifting platform 1, the lifting platform 1 moves upward along the two lifting grooves 24. The lifting platform 1 drives the clamping platform 2 to move. The clamping platform 2 drives the circular mechanical parts that are clamped and fixed to move through the clamping plate 7. At the same time, the grinding motor 10 is activated, which drives the grinding and polishing disc 11 to rotate, thereby grinding and polishing the mechanical parts of different heights.

[0032] In summary, during the use or operation of the overall equipment: when it is necessary to clamp and fix circular mechanical parts to be ground and polished, the rotary motor 3 is started according to the size of the mechanical parts. The rotary motor 3 drives the clamping table 2 to rotate, and the clamping table 2 drives the four clamping components to rotate. Since the two clamping plates 7 on each clamping component are of different sizes, the two required clamping plates 7 are rotated to the lower end of the grinding and polishing disc 11. The mechanical parts are placed on the clamping table 2 between the two clamping plates 7. The clamping motor 8 is started, and the clamping motor 8 drives the bidirectional lead screw 5 to rotate. Since the bidirectional lead screw 5 has two threaded areas 27 with opposite directions, the two clamping seats 6 move in adjacent directions. The clamping seats 6 drive the clamping plates 7 to move, thereby clamping and fixing the mechanical parts. To ensure the normal operation of the bidirectional lead screw 5, accordion covers (not shown in the figure) can be installed between the clamping seats 6 and the clamping groove 4 on both sides to protect the bidirectional lead screw 5.

[0033] When the protective door 12 needs to be closed, the protective motor 16 is started. The protective motor 16 drives the rotating gear 17 to rotate. Since the rotating gear 17 is meshed with the toothed belt 15, the toothed belt 15 drives the limiting strip 14 to move along the limiting groove 13. The limiting strip 14 drives the protective door 12 to move, thus closing the protective door 12. The adjusting motor 21 is started. The adjusting motor 21 drives the rotating rod 22 to rotate. The rotating rod 22 drives the two driving bevel gears 23 to rotate. The driving bevel gears 23 drive the driven bevel gear 26 to rotate. The driven bevel gear 26 drives the screw 25 to rotate. Since the screw 25 is threadedly connected to the lifting platform 1, the lifting platform 1 moves upward along the two lifting grooves 24. The lifting platform 1 drives the clamping platform 2 to move. The clamping platform 2 drives the circular mechanical parts that are clamped and fixed to move through the clamping plate 7. At the same time, the grinding motor 10 is started. The grinding motor 10 drives the grinding and polishing disc 11 to rotate, thereby grinding and polishing the mechanical parts of different heights.

[0034] A controller is provided on one side of the workbench 19. The entire device is controlled by the controller. Since the equipment matched with the controller is a common device and belongs to existing mature technology, its electrical connection relationship and specific circuit structure will not be described in detail here.

[0035] Of all the solutions mentioned above, those involving the connection between two components can be selected according to the actual situation, such as welding, bolt and nut connection, bolt or screw connection, or other known connection methods, which will not be elaborated here. For all the fixed connections mentioned above, welding is preferred. Although embodiments of this utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of this utility model. The scope of this utility model is defined by the appended claims and their equivalents.
