[0031] Please refer to Figures 1-3 , this invention provides a technical solution for a hardware part grinding device:

[0032] A hardware part grinding device includes a base 1. A fixture 2 is installed at the top of the base 1. A bracket 3 is fixedly connected to the top of the base 1. A slide rail 5 is installed on one side of the bracket 3. A lifting frame 4 is slidably connected to the side of the slide rail 5. A support plate 10 is fixedly connected to one side of the lifting frame 4. A motor 8 is installed at the top of the support plate 10. The output end of the motor 8 is drivingly connected to a main shaft 32. A lifting block 24 is slidably connected to the middle of the main shaft 32. A central block 25 is fixedly connected to the bottom end of the main shaft 32. Three support arms 12 are installed on the side of the central block 25. An activity slot 23 is provided inside each support arm 12. An activity block 22 is slidably connected to the inside of each activity slot 23. The bottom end of the activity block 22 is rotatably connected to a transmission rod 13. A grinding head 14 is installed at the bottom end of the transmission rod 13.

[0033] The top end of the activity block 22 is hinged to a hinge rod 15, and the other end of the hinge rod 15 is hinged to the side of the lifting block 24.

[0034] An adjusting cylinder 9 is installed at the top of the support plate 10. The telescopic end of the adjusting cylinder 9 is fixedly connected to a lifting ring 11, and the lifting ring 11 is rotatably connected to the lifting block 24.

[0035] A vertical rod 16 is installed at the bottom of the support plate 10. A gear ring 21 is installed at the bottom end of the vertical rod 16.

[0036] The end of the support arm 12 is rotatably connected to a transmission shaft 20, and a driving gear 30 is installed at the top of the transmission shaft 20. The driving gear 30 is meshed and connected with a toothed ring 21.

[0037] A driving wheel 29 is installed at the bottom end of the transmission shaft 20, and a first transmission wheel 18 is installed at the top end of the transmission rod 13. The first transmission wheel 18 and the driving wheel 29 are connected by a transmission belt 19 for transmission.

[0038] A side frame 26 is installed on one side of the middle part of the support arm 12. The side frame 26 is fixedly connected to a smooth rod 27. A slider 28 is slidably connected to the smooth rod 27. A tensioning wheel 17 is installed at the bottom end of the slider 28. The transmission belt 19 is in rolling connection with the tensioning wheel 17.

[0039] A support 6 is installed at the top end of the support 3, and a lifting cylinder 7 is installed at the top end of the support 6. The telescopic end of the lifting cylinder 7 is fixedly connected to a support plate 10.

[0040] A spline groove is formed on the surface of the main shaft 32, and splines adapted to the spline groove are provided on the inner wall of the lifting block 24.

[0041] A spring 31 is arranged in the movable groove 23. One end of the spring 31 is connected to the movable block 22, and the other end is connected to the support arm 12 for providing a return elastic force for the movable block 22.

[0042] During specific use, place the hardware on the fixture 2 of the base 1, and firmly fix the hardware through the fixture 2. According to the height of the hardware, start the lifting cylinder 7 on the support 6 at the top end of the support 3. The telescopic end of the lifting cylinder 7 drives the support plate 10 to move up and down along the slide rail 5 to adjust the height of the grinding device so that the grinding head 14 and the hardware are in a suitable grinding position.

[0043] Start the motor 8. The output end of the motor 8 drives the main shaft 32 to rotate. Since the spline groove on the surface of the main shaft 32 is adapted to the splines on the inner wall of the lifting block 24, the lifting block 24 rotates together with the main shaft 32. At the same time, start the adjusting cylinder 9. The telescopic end of the adjusting cylinder 9 pushes the lifting ring 11 to move up and down. The lifting ring 11 drives the lifting block 24 to slide up and down along the main shaft 32. When grinding hardware with a smaller size is required, the adjusting cylinder 9 pushes the lifting ring 11 to move upward, and the lifting block 24 slides upward accordingly. The movable block 22 is pulled to slide upward in the movable groove 23 through the hinge rod 15, and the transmission rod 13 and the grinding head 14 are retracted towards the central block 25. When grinding hardware with a larger size is required, the adjusting cylinder 9 pulls the lifting ring 11 to move downward. Under the action of the spring 31, the movable block 22 slides downward, and the transmission rod 13 and the grinding head 14 expand outward.

[0044] During the rotation of the main shaft 32, the vertical rod 16 at the bottom end of the support plate 10 rotates together with the main shaft 32, and the gear ring 21 at the bottom end of the vertical rod 16 also rotates accordingly. The gear ring 21 meshes with the driving gear 30 at the top end of the transmission shaft 20 to drive the transmission shaft 20 to rotate. The driving wheel 29 at the bottom end of the transmission shaft 20 drives the first transmission wheel 18 at the top end of the transmission rod 13 through the transmission belt 19, so that the grinding head 14 rotates while revolving with the support arm 12, and efficiently grinds the hardware.

[0045] During the transmission process, if the transmission belt 19 becomes loose, the slider 28 on the polished rod 27 on the side frame 26 can be adjusted to drive the tension pulley 17 to move up and down, so as to adjust the tension of the transmission belt 19 and ensure the stability of the transmission.

[0046] Through the above operations, efficient and high-quality grinding of hardware with different sizes and shapes can be achieved.

[0047] The above are only the preferred embodiments of the present invention, and the protection scope of the present invention is not limited thereby. For those skilled in the art, various changes and modifications can be made to the present invention. Any changes, modifications, substitutions, integrations and parameter changes made to these embodiments by means of conventional substitutions or the realization of the same functions without departing from the principle and spirit of the present invention fall within the protection scope of the present invention.
