[0034] Reference Figure 2-Figure 4The top of the base 1 is fixedly connected to two shells 2 6, the shell 1 2 is fixedly connected between the two shells 2 6, the inside of the shell 2 6 is fixedly connected to a motor 7, the output end of the motor 7 is fixedly connected to a turntable 8, the middle part of the turntable 8 is rotatably connected to four arc-shaped plates 9, the other side of the arc-shaped plate 9 is rotatably connected to a slider 10, the slider 10 is slidably connected to the middle part of the shell 2 6, the side of the slider 10 away from the arc-shaped plate 9 is fixedly connected to a clamping plate 11, and the outer side of the clamping plate 11 is fixedly connected to an anti-skid pad 12. By driving the motor 7, the turntable 8 can drive one side of the arc-shaped plate 9 to move, at this time, the slider 10 can limit the arc-shaped plate 9, and then the arc-shaped plate 9 can drive the slider 10 and the clamping plate 11 to clamp and position the hardware, and at the same time, the anti-skid pad 12 can be set to improve the stability of the hardware clamping, and at the same time, hardware of different shapes can be clamped.

[0035] Reference Figure 2-Figure 4 A slide groove 28 is provided in the middle of the shell 2 6, and the slider 10 is slidably connected to the middle of the slide groove 28. The slide groove 28 can limit the slider 10, thereby preventing the slider 10 from tilting during the movement, and the clamping plate 11 can only move in parallel, thereby effectively driving the anti-slip pad 12 to clamp hardware of different shapes. The side of the motor 7 away from the turntable 8 is fixedly connected to a flip assembly, and the bottom of the base 1 is fixedly connected to a collecting box 17. The outer side of one of the shells 2 6 is fixedly connected to a dust suction assembly, and the dust generated during grinding can be sucked out by the dust suction assembly, thereby preventing dust from floating inside the shell 2 when grinding is completed, and avoiding employees from inhaling dust into their bodies when turning or assembling hardware, thereby improving the safety of employees.

[0036] Reference Figure 2-Figure 4 The flipping assembly includes a connecting disk 13, which is fixedly connected to the side of the motor 7 away from the turntable 8. A gear 14 is fixedly connected to the outer side of the connecting disk 13, and an electric push rod 2 15 is fixedly connected to the inside of the housing 6.

At this time, the clamped hardware can be turned over without the need for employees to manually turn the hardware over, which can facilitate the polishing of the hardware. At the same time, the four sides of the unpolished position can be polished after the hardware is turned over, which can improve the polishing efficiency. The rotation angle of the connecting disk 13 is 270°. The described rotation angle can prevent the problem of wire twisting when the motor 7 drives the clamped hardware to flip over.

A filter plate 20 is slidably connected to the middle of the shell 19, and a baffle 22 is fixedly connected to the outside of the filter plate 20. The baffle 22 is in contact with the shell 19. By driving the vacuum pump 18, the air inlet pipe 21 can suck the dust floating in the shell 2 into the shell 19. At this time, the dust can be filtered and collected by the filter plate 20, thereby preventing the dust from being discharged and affecting the environment. A sealing assembly is fixedly connected to the outside of the shell 19.

[0038] Reference Figure 5 and Figure 6 The sealing assembly includes a sleeve 23, which is fixedly connected to the outer side of the shell 19. A compression spring 24 is fixedly connected to the inside of the sleeve 23. The other end of the compression spring 24 is fixedly connected to a partition 25. A rotating rod 26 is rotatably connected to the middle part of the partition 25. One end of the rotating rod 26 is fixedly connected to a pressure plate 27. A movable groove 29 is opened in the middle part of the sleeve 23, and the pressure plate 27 is slidably connected to the middle part of the movable groove 29. By inserting the filter plate 20 into the shell 19, and after the filter plate 20 is fully entered, the partition 25 is driven by pulling the rotating rod 26 to compress the compression spring 24 and move the pressure plate 27. When the rotating rod 26 cannot move, the rotating rod 26 is flipped, and the pressure plate 27 can be flipped to a position parallel to the baffle 22. Finally, the rotating rod 26 is released and the pressure plate 27 can squeeze the baffle 22 under the action of the compression spring 24, so that the filter plate 20 can be installed and air leakage can be prevented.

[0039] Reference Figure 5 and Figure 6 , by pulling the rotating rod 26, the pressure plate 27 slides in the middle of the movable groove 29. When the pressure plate 27 cannot move, the rotating rod 26 is flipped over. At this time, the pressure plate 27 and the baffle 22 are not in a parallel position. At this time, the filter plate 20 can be removed and the collected dust can be cleaned conveniently. The end of the rotating rod 26 away from the sleeve 23 is fixedly connected with a handle, and an anti-skid groove is provided on the outside of the handle. The rotating rod 26 can be pulled or rotated more effectively and comfortably through the handle and the anti-skid groove.

[0040] Reference Figure 1 The bottom of the base 1 is fixedly connected with a support rod, and the bottom of the support rod is fixedly connected with a pad. The stability of the base 1 can be improved by the support rod and the pad, preventing the base 1 from being displaced when the hardware is polished.

[0041] Working principle: When in use, the turntable 8 can be rotated by driving the motor 7. At this time, the arc plate 9 can be limited by the slider 10, and then the arc plate 9 can drive the slider 10 and the clamping plate 11 to move at the same time. At this time, the hardware can be clamped and positioned. At the same time, the anti-slip pad 12 can improve the stability of the hardware clamping. At the same time, hardware of different shapes can be clamped. The rack plate 16 can be moved by driving the electric push rod 15. When the rack plate 16 moves, it can drive the gear 14 to flip. At this time, the clamped hardware can be turned over, and the employees do not need to turn the hardware over manually, which can facilitate the grinding of the hardware. At the same time, the four sides of the position to be polished can be polished after the hardware is turned over, which can improve the efficiency of polishing.

[0042] Among them, by driving the vacuum pump 18, the air intake pipe 21 can suck the dust floating in the shell 2 into the shell 19. At this time, the dust can be filtered and collected by the filter plate 20, thereby preventing the dust from being discharged and affecting the environment. When the filter plate 20 is installed, the filter plate 20 is inserted into the shell 19. After the filter plate 20 enters, the baffle plate 22 will contact the shell 19. At this time, by pulling the rotating rod 26 and rotating the rotating rod 26, the partition plate 25 can compress the compression spring 24 and drive the pressure plate 27 to move when the rotating rod 26 moves. When the rotating rod 26 cannot move, the rotating rod 2 6 is flipped, at this time, the pressure plate 27 can be flipped and moved to a position parallel to the baffle 22. Finally, by loosening the rotating rod 26 and under the action of the compression spring 24, the pressure plate 27 can be pressed against the baffle 22, thereby improving the sealing between the housing 19 and the filter plate 20. When the filter plate 20 needs to be removed, the rotating rod 26 is pulled and rotated in the opposite direction. At this time, the pressure plate 27 can be limited by the movable groove 29, and then the pressure plate 27 can be moved to a position not parallel to the baffle 22. At this time, the filter plate 20 can be quickly removed and cleaned or replaced.
