It should be understood that the specific embodiments described herein are merely for explaining the present utility model and are not intended to limit the present utility model.

[0019] To address the technical problem of high procurement and manufacturing costs for automatic polishing equipment, this utility model provides a sandpaper polishing auxiliary tool that can reduce procurement and manufacturing costs.

[0020] It should be noted that the sandpaper polishing auxiliary tool described in this utility model is used for, but not limited to, metal discs, etc. For ease of explanation, this utility model only uses the application of a sandpaper polishing auxiliary tool to a metal disc as an example for explanation. The principle of applying a sandpaper polishing auxiliary tool to other types of equipment is essentially the same as the principle of applying it to a metal disc, and will not be described in detail here.

[0021] Please see Figures 1 to 3 ,in Figure 1This is a schematic diagram of the structure of a sandpaper polishing auxiliary tool according to an embodiment of the present invention. The sandpaper polishing auxiliary tool includes a worktable 1, a rotating component 2, and a pressing component 3. The rotating component 2 is installed on the worktable 1 and includes a turntable 21 and a driving component 22. The driving component 22 is located below the turntable 21 and is used to drive the turntable 21 to rotate. The pressing component 3 includes a support rod 31, a movable rod 32, a sliding sleeve 33, and a pressing rod 34. The bottom end of the support rod 31 is fixedly connected to the worktable 1 and is located on one side of the turntable 21. One end of the movable rod 32 is movably connected to the support rod 31, allowing the other end of the movable rod 32 to move in all directions. The sliding sleeve 33 is located above the turntable 21 and is sleeved on the movable rod 32. The top end of the pressing rod 34 is fixedly connected to the sliding sleeve 33, and the bottom end of the pressing rod 34 is used to press down the sandpaper.

[0022] In this embodiment, the rotating structure of the metal disc is formed by the turntable 21 and the driving component 22. The movable rod 32 allows the pressing rod 34 to cover all surfaces of the metal disc as the movable rod 32 moves. Furthermore, under the action of the pressing rod 34, the sandpaper is pressed onto the rotating metal disc, thus achieving autonomous grinding and polishing without the need for complex product fixing components, effectively reducing procurement and manufacturing costs. At the same time, replacing the polishing disc with cheaper sandpaper effectively reduces the cost of consumables.

[0023] Furthermore, the drive unit 22 uses a servo motor.

[0024] Furthermore, the bottom end of the turntable 21 is fitted onto the movable end of the drive component 22. The movable end of the drive component 22 has a protrusion, and the bottom end of the turntable 21 has a slot. The protrusion is inserted into the slot to realize the rotational connection between the turntable 21 and the drive component 22. That is, the turntable 21 is a detachable connection and can be replaced. Therefore, there are multiple turntables 21, and the top surface of each turntable 21 is different and corresponds to different specifications of metal discs.

[0025] Furthermore, the sliding sleeve 33 is slidably mounted on the movable rod 32. When changing to a different size turntable 21, the pressing rod 34 can be moved to a suitable position by moving the sliding sleeve 33.

[0026] In one embodiment, the top surface of the turntable 21 is provided with a rounded corner groove 211.

[0027] In this embodiment, the top surface of the turntable 21 is slightly concave inward and the edge is rounded, forming a rounded corner groove 211. This groove is designed to fit the metal disc and prevent the metal disc from falling off as the turntable 21 rotates.

[0028] In one embodiment, the rotating assembly 2 further includes a chassis 23, which is rotatably connected to the turntable 21 and is used to mount the turntable 21 to the top surface of the workbench 1. The driving component 22 is mounted on the bottom surface of the workbench 1 and passes through the workbench 1 and the chassis 23 in sequence to drive the turntable 21 to rotate.

[0029] In this embodiment, the chassis 23 is fixedly connected to the workbench 1 with screws to ensure stability during operation. Both the chassis 23 and the workbench 1 have through holes to facilitate the transmission connection between the movable end of the drive component 22 and the turntable 21.

[0030] In one embodiment, the pressing assembly 3 further includes a spring 35, one end of which is hinged to the top end of the support rod 31, and the other end of which is hinged to the top end of the sliding sleeve 33.

[0031] In this embodiment, hooks are provided at both ends of the spring 35 to facilitate the spring 35 to hook the top of the support rod 31 and the top of the sliding sleeve 33. The function of the spring 35 is to prevent the movable rod 32 from moving down due to its own weight and affecting the rotating turntable 21 or metal disc. Under the action of the spring 35, the pressing rod 34 never contacts the turntable 21. Only when contact is needed can the operator press the movable rod 32.

[0032] In one embodiment, the pressing assembly 3 further includes an eye screw 36, the top of the sliding sleeve 33 is provided with a threaded through hole 331, the screw end of the eye screw 36 is used to be threaded into the threaded through hole 331, and the hook end of the eye screw 36 is used to hinge one end of the spring 35.

[0033] In this embodiment, the eye screw 36 is used to facilitate the hook connection of the spring 35.

[0034] In one embodiment, the length of the screw end of the eye screw 36 is greater than the length of the threaded through hole 331.

[0035] In this embodiment, the length of the screw end of the eye screw 36 is greater than the length of the threaded through hole 331, so that the eye screw 36 can fix the sliding sleeve 33 by tightly abutting against the movable rod 32, thus preventing the sliding sleeve 33 from moving on its own during operation.

[0036] In one embodiment, a ring 311 is fixedly connected to the top end of the support rod 31, and the ring 311 is hinged to the other end of the spring 35.

[0037] In this embodiment, the function of the ring 311 is to facilitate the hook connection of the spring 35.

[0038] In one embodiment, the bottom end of the pressing rod 34 is arc-shaped.

[0039] In this embodiment, the bottom end of the pressing rod 34 is arc-shaped, which makes the pressing rod 34 press the sandpaper more smoothly and matches the arc-shaped surface of the metal disc, avoiding sandpaper wrinkles and preventing the pressing rod 34 from causing pressing marks on the metal disc.

[0040] In one embodiment, one end of the movable rod 32 is provided with a ball 321, and a groove 312 is provided on one side of the support rod 31. The ball 321 is adapted to the groove 312 and is movably embedded in the groove 312.

[0041] In this embodiment, in the initial state, the centers of the movable rod 32, the support rod 31 and the turntable 21 are coplanar. Through the connection between the ball 321 and the groove 312, the movable rod 32 can move in all directions around the ball 321, so that the movable rod 32 can carry the pressing rod 34 to different radii on the metal plate for polishing.

[0042] In one embodiment, the other end of the movable rod 32 is fitted with a glove 322.

[0043] In this embodiment, the purpose of the gloves 322 is to facilitate the operation of the movable lever 32 by the staff.

[0044] To better understand this utility model, the following is combined with... Figures 1 to 3 The technical solution of this utility model is described in detail below: First, the metal disc is placed on the turntable 21 and positioned using the rounded corner groove 211. Next, the drive unit 22 is activated, causing the turntable 21 to rotate along with the metal disc. Then, sandpaper is placed on the metal disc with one hand, ensuring it remains firmly in hand throughout the process. This prevents the sandpaper from slipping off due to rotation and allows for adjustment of its position, avoiding prolonged use in one spot. Once all areas of the sandpaper have been used, a new sheet is used, eliminating the need to replace the polishing disc and making operation more convenient. Then, the other hand presses down on the movable lever 32, causing the bottom of the pressing rod 34 to press down on the sandpaper. Under the action of the pressing rod 34, the sandpaper makes close contact with the rotating metal disc, achieving autonomous polishing. Finally, the movable lever 32 is rotated left and right, allowing the pressing rod 34 to polish all surfaces of the metal disc with the sandpaper. The entire process is quick and convenient, ensuring polishing efficiency while significantly simplifying the equipment structure and reducing manufacturing and procurement costs, making it particularly appealing to small and medium-sized enterprises.
