Detailed Implementation

[0026] The present invention will now be described in conjunction with specific embodiments.

[0027] Example 1, as Figures 1 to 3As shown, a sandpaper polishing mechanism includes a base 1, a translation drive mechanism 2, a translation movable seat 3, a sandpaper mounting block 41, and sandpaper 42. The translation drive mechanism 2 is mounted on the base 1 and drives the translation movable seat 3 to move horizontally back and forth. The sandpaper 42 is mounted on the sandpaper mounting block 41.

[0028] Among them, such as Figures 1 to 3 As shown, the sanding mechanism also includes a fine-tuning movable seat 5 and an angle adjustment plate 6. The fine-tuning movable seat 5 is horizontally slidably mounted on the upper end of the translational movable seat 3 along the front-back direction, and a fine-tuning drive mechanism 7 is installed between the fine-tuning movable seat 5 and the translational movable seat 3. The fine-tuning drive mechanism 7 includes a fine-tuning drive screw 71 that is rotatably mounted on the translational movable seat 3 via a bearing and extends along the front-back direction. A fine-tuning drive handwheel 72 is installed at one end of the fine-tuning drive screw 71. A fine-tuning screw nut 73 is fixedly installed on the fine-tuning movable seat 5, and the fine-tuning screw nut 73 cooperates with the fine-tuning drive screw 71.

[0029] Furthermore, such as Figures 1 to 3 As shown, the angle adjustment plate 6 is screwed to fix the linear drive module 81, and the drive end of the linear module is equipped with a grinding movable frame 82. The sandpaper mounting block 41 is installed on the grinding movable frame 82.

[0030] Furthermore, the angle adjustment plate 6 is provided with a shaft portion 61, which is rotatably mounted on the upper end of the fine-tuning movable seat 5 via bearings; the angle adjustment plate 6 has at least three internally threaded holes arranged in a circular array on the periphery of the shaft portion 61, and each internally threaded hole is screwed with a locking screw 9; the upper end of the fine-tuning movable seat 5 is provided with an arc-shaped through hole 51 corresponding to each locking screw 9, and each locking screw 9 passes through the corresponding arc-shaped through hole 51; when each locking screw 9 is in the tightened state, the angle adjustment plate 6 is fixed to the upper end of the fine-tuning movable seat 5 by the locking screw 9.

[0031] It should be noted that the fine-tuning seat 5 is provided with a vertically arranged movable seat vertical plate 52, and the angle adjustment plate 6 is also arranged vertically. Each arc-shaped through hole 51 is opened at the upper end of the movable seat vertical plate 52.

[0032] When the sandpaper grinding mechanism of this embodiment is used to grind the workpiece, the translation drive mechanism 2 first drives the translation movable seat 3 to move forward and move the translation movable seat 3 to the working position; after the translation movable seat 3 moves forward to the working position, the linear drive module 81 is activated, and the linear drive module 81 drives the grinding movable frame 82, the sandpaper mounting block 41 and the sandpaper 42 to reciprocate linearly, thereby making the sandpaper 42 grind the surface of the workpiece.

[0033] It should be emphasized that, for the fine-tuning drive mechanism 7 installed between the fine-tuning movable seat 5 and the translational movable seat 3, the operator can rotate the fine-tuning drive handwheel 72 to rotate the fine-tuning drive screw 71. The rotating fine-tuning drive screw 71 drives the fine-tuning screw nut 73 to move back and forth, thereby causing the fine-tuning movable seat 5 to move back and forth relative to the translational movable seat 3 to adjust the relative position between the sandpaper 42 and the workpiece during the grinding operation, so that the sandpaper 42 can stably grind the workpiece.

[0034] Furthermore, the angle adjustment plate 6 is mounted on the upper end of the fine-tuning movable seat 5 via its shaft 61. When the angle of the angle adjustment plate 6 needs to be adjusted, the operator only needs to loosen the locking screws 9, then rotate the angle adjustment plate 6 to the desired position around the shaft 61 as the center of rotation, and then tighten the locking screws 9 to keep the angle adjustment plate 6 and the fine-tuning movable seat fixed. Since the angle adjustment plate 6 can be adjusted relative to the fine-tuning movable seat 5, the sandpaper grinding mechanism of this embodiment can adjust the angle of the sandpaper 42 to meet the requirements of different angle grinding operations, and can be effectively applied to the grinding of the edges and corners of workpieces.

[0035] In summary, the sandpaper grinding mechanism of this embodiment has the advantages of novel structural design and good adjustability, and can be effectively applied to the grinding of the edges and corners of workpieces.

[0036] Example 2, as Figures 1 to 3 As shown, the difference between this embodiment 2 and embodiment 1 is that: the upper end of the translational movable seat 3 is equipped with a guide post 74 extending in a straight line along the front-back direction, and the lower end of the fine-tuning movable seat 5 is equipped with a guide sleeve 75, and the guide post 74 and the guide sleeve 75 cooperate with each other.

[0037] Through the guide pair structure composed of guide post 74 and guide sleeve 75, this embodiment 2 can ensure that the fine-tuning movable seat 5 moves smoothly and accurately horizontally along the front and rear directions.

[0038] Example 3, as Figure 1 and Figure 2 As shown, the difference between this embodiment 3 and embodiment 1 is that the translation drive mechanism 2 includes a cylinder mounting seat 21 fixedly installed on the base 1. The cylinder mounting seat 21 is equipped with a translation drive cylinder 22 that moves horizontally in the front-back direction. The outer end of the piston rod of the translation drive cylinder 22 is connected to the translation movable seat 3.

[0039] During the process of the translation drive mechanism 2 driving the translation movable seat 3 to move horizontally in the front-back direction, the translation drive cylinder 22 is activated and drives the translation movable seat 3 to move through its piston rod.

[0040] Example 4, as Figures 1 to 3 As shown, the difference between this embodiment four and embodiment one is that the translational movable seat 3 is slidably mounted on the upper end of the base 1 via the guide rail slider pair 100. The guide rail slider pair 100 includes a linear guide rail 101 that is screwed to the upper end of the base 1 and extends horizontally along the front-back direction, and a linear slider 102 that is screwed to the translational movable seat 3. The linear guide rail 101 and the linear slider 102 cooperate with each other.
