Description

Technical Field

[0001] This utility model relates to the technical field of grinding equipment accessories, specifically a grinding device for pin production. Background Technology

[0002] As is well known, a pin, or shank, is a cylindrical part made of wood, metal, or other materials, especially used to fasten several individual objects together or as a support suspending one object from another. There are many types of pins, and the spiral anti-loosening pin is a relatively common type. In the production and processing of spiral anti-loosening pins, in order to improve the appearance quality of the pins, their outer surface needs to be polished. The spiral anti-loosening pin outer surface polishing device is a device used to polish the outer surface of spiral anti-loosening pins, and it is widely used in the field of pin production.

[0003] Upon investigation, a Chinese utility model patent disclosed a spiral anti-loosening pin outer surface grinding device (publication number: CN211516936U), which includes a worktable, a support plate, a drive motor, a chuck assembly, and a grinding mechanism. The bottom of the worktable is provided with four sets of support legs. It also includes two sets of support plates, an adjusting plate, an adjusting threaded rod, an adjusting knob, a rotating plate, a sliding plate, a telescopic rod, a limiting rod, and a fixing frame. The bottom ends of the two sets of support plates are respectively connected to the front right side and the rear right side of the top of the worktable, and the top ends of the two sets of support plates are respectively connected to the front and rear sides of the bottom of the adjusting plate. The top of the adjusting plate is provided with an adjusting threaded hole.

[0004] The aforementioned patent incorporates a limiting mechanism to restrict the grinding path of the grinding wheel in the grinding mechanism. This reduces the difficulty of uniformly grinding the outer surface of the spiral anti-loosening pin, thereby reducing the difficulty of ensuring high grinding quality and improving the reliability of the grinding device, thus enhancing its practicality. However, the grinding process generates a large amount of dust and iron filings. These iron filings often accumulate inside the device, requiring subsequent cleaning by the user, which affects the device's processing efficiency. The accumulation of iron filings may also affect the quality of the next processing step, impacting the grinding effect.

[0005] Therefore, this utility model provides a grinding device for pin production to solve the above problems. Utility Model Content

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] This utility model provides a grinding device for pin production, such as... Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the pin-making grinding device includes a base plate 1, a worktable 2 fixedly mounted on the base plate 1, multiple support rods 3 fixedly mounted on the worktable 2, a top plate 4 fixedly mounted on the multiple support rods 3, a grinding chamber 5 fixedly mounted on the worktable 2, and a cleaning mechanism located at the bottom of the top plate 4 for grinding the pins and removing iron filings.

[0028] The cleaning mechanism includes multiple cylinders 6 fixedly installed at the bottom of the top plate 4, cleaning rings 7 fixedly installed on the movable ends of the multiple cylinders 6, cleaning brushes 8 fixedly installed on the side surfaces of the cleaning rings 7, baffles 9 slidably installed on the side surfaces of the multiple cylinders 6, a top cover 10 sleeved on the side surfaces of the baffles 9, a motor 11 fixedly installed on the baffles 9, a connecting shaft 12 rotatably installed inside the baffles 9, a polishing disc 13 fixedly installed on the connecting shaft 12, and a nozzle 14 fixedly installed on the baffles 9.

[0029] The side surface of the baffle 9 is in contact with the inner wall of the top cover 10. The output end of the motor 11 passes through the baffle 9. The output end of the motor 11 is fixedly connected to the end of the connecting shaft 12 away from the grinding disc 13. Multiple nozzles 14 are provided and are arranged in a ring array on the baffle 9.

[0030] When using the pin-making grinding device, first place the base plate 1 in a suitable position, then place the pin inside the grinding chamber 5. Next, activate multiple cylinders 6 on the top plate 4. The moving ends of the cylinders 6 drive the cleaning ring 7, baffle 9, and top cover 10 to move downwards synchronously. During this movement, the top cover 10 connects to the top of the grinding chamber 5, and the cooperation of the baffle 9 and top cover 10 seals the grinding chamber 5, preventing iron filings from flying out during pin grinding. The cleaning ring 7 and baffle 9 continue to move downwards until the grinding disc 13 contacts the pin. Then, activate the motor 11. The output shaft of the motor 11 drives the connecting shaft 12 to rotate synchronously. The rotation of the connecting shaft 12 drives the grinding disc 13, which is fixedly connected to it, to rotate synchronously. The rotation of the grinding disc 13 polishes the pins. Coolant is sprayed through nozzle 14, and the airflow from the rotating grinding disc 13 disperses the iron filings mixed with coolant. The grinding chamber 5 is sealed by the cooperation of the baffle 9 and the top cover 10, leaving the iron filings mixed with coolant on the inner wall of the grinding chamber 5. After polishing, the cylinder 6 is restarted. The moving end of the cylinder 6 drives the cleaning ring 7 and cleaning brush 8 to continue moving downwards. At this point, the pins block the grinding disc 13, so the baffle 9 no longer moves downwards. The cleaning ring 7 and cleaning brush 8 clean the inside of the grinding chamber 5, reducing the accumulation of iron filings inside the device, improving processing efficiency and quality. The retraction of the moving end of the cylinder 6 brings each part back to its initial position.

[0031] Furthermore, in order to secure the pins inside the grinding chamber 5, such as... Figure 1 , Figure 2 and Figure 5 As shown, the grinding chamber 5 is provided with a mounting base 15 inside, and the mounting base 15 has multiple sliding grooves 16 inside. The sliding grooves 16 are arranged in a circular array on the mounting base 15. A first electric push rod 18 is fixedly connected inside the grinding chamber 5.

[0032] The movable end of the first electric push rod 18 is fixedly connected to a clamping block 17, which is slidably installed inside the slide groove 16.

[0033] When using the pin-making grinding device, the pin is placed inside the mounting base 15. Then, by activating multiple first electric push rods 18, the movable ends of the first electric push rods 18 drive multiple clamping blocks 17 to move inward along the slide groove 16 until the pin is clamped. Then, the pin is ground by the grinding disc 13, which prevents the pin from shaking during grinding and improves stability.

[0034] It should be noted that, in order to collect the iron filings produced during polishing, such as... Figure 1 , Figure 2 and Figure 6 As shown, a second electric push rod 19 is fixedly connected to the top of the base plate 1, and a material collection hopper 20 is fixedly connected to the movable end of the second electric push rod 19. The material collection hopper 20 is located at the bottom of the grinding chamber 5.

[0035] A filter plate 21 is fixedly connected inside the hopper 20, and a liquid collection tank 22 is movably connected to the top of the bottom plate 1. The liquid collection tank 22 is located at the bottom of the hopper 20.

[0036] When the pin-making grinding device is in use, the pin is ground by the grinding disc 13. The iron filings mixed with the coolant enter the inside of the grinding chamber 5 and the collection hopper 20. The iron filings remaining on the inner wall of the grinding chamber 5 are cleaned by the cleaning mechanism and fall into the inside of the collection hopper 20. Then, the coolant is filtered by the filter plate 21 and enters the inside of the liquid collection tank 22. By activating the second electric push rod 19, the collection hopper 20 is lowered, so that the iron filings on the filter plate 21 can be removed and recycled.

[0037] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
