This mechanism is mainly used in industries such as furniture manufacturing. It is designed to efficiently and accurately grind door panels to make their surfaces smooth and meet product quality requirements. Accurately grinding both sides of the door panel spherical structure helps to ensure the dimensional accuracy of the door panel.

[0028] The grinding mechanism 3 includes a support rod 31, which is fixedly connected to both sides of the slider 22. The upper end of the support rod 31 is fixedly connected to a connecting rod 32, and an arc cover 33 is fixedly connected between the two connecting rods 32. A one-way rotating mechanism 34 is fixedly connected to the surface of the support rod 31. The two sliders 22 are driven to move inward inside the box body 1 through the rotation of the two-way threaded rod 21, and the slider 22 slides within the box body through the support rods 31 fixed on both sides. The movement of the slider 22 drives the support rod 31 to move. When the support rod 31 moves, the arc cover 33 is driven to move through the connecting rod 32 to wrap the spherical object to be polished, and the polishing can be carried out by hand at the same time. This can save a lot of physical strength and improve the efficiency of polishing. The synchronization mechanism 4 includes a limiting slide groove 41, which is fixed to the surface of the arc cover 33 and is symmetrically arranged. The internal sliding connection of the limiting slide groove 41 is connected to the limiting slide block 42. The top is fixedly connected with a cross bar 43, and a spring 44 is arranged inside the limiting slide groove 41. Oblique rods 45 are fixedly connected with both sides of the cross bar 43. A detachable roller 46 is rotatably connected between the two oblique rods 45, and a grinding sandpaper 8 is installed between the two rollers 46. A connecting rod 1 47 is hinged on the surface of the cross bar 43, and a connecting rod 2 48 is rotatably connected inside the connecting rod 32. One end of the connecting rod 2 48 is rotatably connected with a connecting rod 3 49, and the other end of the connecting rod 1 47 is rotatably connected to one end of the connecting rod 2 48, and the other end of the connecting rod 3 49 is hinged to the surface of another cross bar 43. When the cross bar 43 moves downward, the connecting rod 1 47 drives the connecting rod 2 48 to rotate. When the connecting rod 2 48 rotates, it pushes the connecting rod 3 49. At the same time, the connecting rod 3 49 drives the upper cross bar 43 to slide upward, so that the two rollers 46 will move up and down relatively, and the grinding sandpaper 8 on the roller 46 will be relatively tightened, thereby increasing the friction with the object to be polished and achieving better polishing.

[0029] The one-way rotation mechanism 34 includes an extension rod 341, which is fixedly connected to one end of the roller 46. A disk 342 is fixedly connected to one end of the extension rod 341.

The self-locking mechanism 5 includes a square block 51, which is fixedly connected to the side of another roller 46. An L-shaped rod 52 is fixedly connected to the upper end of the support rod 31.

[0030] The hand-held mechanism 7 includes a handle 71, which is fixedly connected to the surface of the box body 1, and a gripping slider 72 is slidably connected to the inside of the handle 71.

When the roller 46 rotates, the grinding sandpaper 8 is driven to rotate on the surface of the roller 46, so that the grinding sandpaper can be moved to the roller 46 at the lower end, which can save a lot of time for replacing the grinding sandpaper 8. At the same time, when the grinding sandpaper is used on a large area, it only needs to quickly pinch and release the gripping slider 72, and the used grinding sandpaper can also be quickly transferred to the roller 46 at the lower end, which further improves the grinding efficiency. When the grinding sandpaper is used on a large area, it only needs to quickly pinch and release the gripping slider 72, and the used grinding sandpaper can also be quickly transferred to the roller 46 at the lower end, which further improves the grinding efficiency.

[0031] The use method and advantages of the present invention: When the door panel spherical structure grinding mechanism based on double-sided contact is used, the working process is as follows:

[0032] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Fig. 9 , Fig.10 As shown;

[0033] When in use, first place the sandpaper 8 on the roller 46, and manually clamp the other side on the surface of the other roller 46, so that the sandpaper 8 fits the inner groove surface of the arc cover 33, and then turn the knob 23. When the knob 23 is rotated, it drives the bidirectional threaded rod 21 to rotate inside the box body 1. The rotation of the bidirectional threaded rod 21 drives the two sliders 22 to move inward inside the box body 1, and the sliders 22 slide within the box body through the support rods 31 fixed on both sides. The movement of the slider 22 drives the support rod 31 to move. When the support rod 31 moves, it drives the arc cover 33 to move through the connecting rod 32 to wrap the spherical object to be polished, and polishing is performed by hand at the same time, which can save a lot of physical strength and improve the efficiency of polishing. Then, the staff holding the handle 71 pinches the grip slider 72 before grinding, and the grip slider 72 slides inside the handle 71, driving the alloy rod 74 and the horizontal plate 75 at the upper end of the alloy rod 74 to move downward at the same time. When the horizontal plate 75 moves downward, it drives the slide bar 63 to slide downward, and when the slide bar 63 moves downward, it pulls the fixed rod 61 with the horizontal groove 62 to move the fixed rod 61 downward. Before that, when the fixed rod 61 is forced to move by the knob 23, the slide bar 63 will passively slide inside the horizontal groove 62, and the arc cover 33 at the other end is synchronized through the telescopic rod 64.

[0034] When the fixed rod 61 moves downward, it drives the cross bar 43 downward. When the cross bar 43 moves downward, it drives the limiting slider 42 to slide inside the limiting slide groove 41. At the same time, the two ends of the cross bar 43 drive the rollers 46 to slide downward through the inclined rods 45. When the cross bar 43 moves downward, it drives the connecting rod 2 48 to rotate through the connecting rod 1 47. When the connecting rod 2 48 rotates, it pushes the connecting rod 3 49. The connecting rod 3 49 drives the upper cross bar 43 to slide upward at the same time. In this way, the two rollers 46 will move up and down relatively, and the grinding sandpaper 8 on the roller 46 will be relatively tightened, thereby increasing the friction with the object to be polished and achieving better polishing. When the cross bar 43 at the upper end moves upward, the square block 51 on the side is driven to move upward at the same time and is stuck in the arc groove 53. The square block 51 is stuck in the arc groove 53 to prevent the upper roller 46 from rotating, so that the sandpaper will not move due to external force during sanding. When the roller 46 at the lower end moves, the one-way pawl 343 on the disk 342 is driven to move through the extension rod 341. When moving downward, the one-way pawl 343 will not mesh with the ratchet 344, so the roller 46 at the lower end will move straight downward when moving downward.

[0035] When the grinding is completed, the two rollers 46 will be reset by the spring 44 and the telescopic spring 73, and when the roller 46 at the lower end is upward, the one-way pawl 343 will engage with the ratchet 344 and drive the disc 342 to rotate. When the disc 342 rotates, it will drive the roller 46 to rotate through the extension rod 341. When the roller 46 rotates, it drives the grinding sandpaper 8 to rotate on the surface of the roller 46, so that the grinding sandpaper can be moved to the roller 46 at the lower end. This will save a lot of time for replacing the grinding sandpaper 8. At the same time, when using the grinding sandpaper on a large area, you only need to quickly pinch and release the grip slider 72 to quickly transfer the used grinding sandpaper to the roller 46 at the lower end, thereby further improving the grinding efficiency.

[0036] The above shows and describes the basic principles, main features and advantages of the present invention. Technical personnel in this industry should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are only preferred examples of the present invention and are not used to limit the present invention.
