DETAILED DESCRIPTION OF THE EMBODIMENTS

[0018] In order to make the technical means, creative features, achieved purposes and functions of the present utility model easy to understand, the present utility model will be further described below in conjunction with the drawings and specific embodiments.

[0019] As Figures 1 to 3As shown in the figure, a belt polishing operation mechanism in a polishing device proposed by the present utility model includes a frame 1. A working frame 2 is slidably connected to the frame 1 in the vertical direction. A driving structure 3 for driving the vertical movement of the working frame 2 is provided between the working frame 2 and the frame 1. The driving structure 3 mainly includes a driving motor and a gear-rack structure, and the working frame 2 can be driven to move up and down through the driving motor and the gear-rack structure. The working frame 2 is provided with a polishing assembly for enabling the belt to perform a polishing operation and a guiding assembly for positioning and guiding the belt.

[0020] The polishing assembly includes a mounting seat 4 slidably connected to the working frame 2 in the vertical direction, and a polishing contact block 5 provided at the lower end of the mounting seat 4 for the belt to wind around. The polishing contact block 5 is made of an elastic material, and an elastic structure is provided between the working frame 2 and the mounting seat 4 to limit the sliding of the mounting seat 4. A section of the belt wound around the polishing contact block 5 can contact the workpiece to be polished. During use, when the working frame 2 drives the mounting seat 4 to move downward, after the belt wound around the polishing contact block 5 contacts the workpiece, the displacement between the mounting seat 4 and the working frame 2 can avoid excessive extrusion, and at the same time, the elastic structure ensures effective contact between the belt and the workpiece.

[0021] The elastic structure includes a limiting block 6 provided on the side wall of the mounting seat 4, a connecting block 7 provided on the working frame 2 and located directly above the limiting block 6, and an elastic member 8 provided between the limiting block 6 and the connecting block 7. The elastic member 8 can be a spring, and the spring is vertically arranged. When the belt at the position of the polishing contact block 5 contacts the workpiece, it causes the limiting block 6 and the connecting block 7 to move towards each other, compressing the elastic member 8, enabling the mounting seat 4 and the polishing contact block 5 to move relative to each other, avoiding excessive extrusion of the workpiece, and at the same time ensuring a stable pressure between the belt and the workpiece.

[0022] To limit the relative displacement amount between the working frame 2 and the mounting seat 4, an induction limiting structure is provided between the working frame 2 and the mounting seat 4. The induction limiting structure includes a limiting screw 9 vertically arranged and threadedly connected to the limiting block 6, and an inductor 10 provided on the working frame 2 for sensing the limiting screw 9. The limiting screw 9 passes through the elastic member 8, and the upper end surface of the limiting screw 9 protrudes above the upper end surface of the connecting block 7. The inductor 10 is located directly above the limiting screw 9 and is used to sense the limiting screw 9. The inductor 10 can be a displacement inductor 10 or a distance inductor 10. When the mounting seat 4 and the working frame 2 move relative to each other, the elastic member 8 contracts, causing the limiting screw 9 to also move relative to the connecting block 7 and the inductor 10, that is, the upper end surface of the limiting screw 9 approaches the inductor 10. The inductor 10 can timely sense the limiting screw 9 and output a corresponding induction signal to the control system of the corresponding polishing device, and finally, the driving structure 3 can be controlled to limit the further downward movement of the working frame 2 to achieve a limiting effect.

[0023] In addition, the working rack 2 is provided with a physical limit block 11 for restricting the moving distance of the mounting seat 4 relative to the working rack 2. The physical limit block 11 can be abutted by the limiting block 6 to limit the continuous movement of the mounting seat 4 relative to the working rack 2. By the physical limit block 11 abutting against the limiting block 6, mechanical limit can be achieved, avoiding damage caused by excessive displacement of the mounting seat 4 and the working rack 2.

[0024] In the embodiment, the guiding assembly includes a plurality of guiding sheet metal parts 12 arranged on the mounting seat 4 and two guiding sheets 13 respectively arranged on both sides of the mounting seat 4. The guiding sheets 13 are connected between the mounting seat 4 and the polishing abutting block 5, and both edges of the two ends of the guiding sheets 13 protrude from the polishing abutting block 5, so that the abrasive belt can be stuck between the two guiding sheets 13 to avoid the abrasive belt detaching from the polishing abutting block 5. In addition, a roller 14 for preventing the abrasive belt from detaching from the polishing abutting block 5 is arranged between the two guiding sheets 13, and a gap for the abrasive belt to pass through is left between the roller 14 and the mounting seat 4. Through the above structure, the moving position of the abrasive belt can be effectively limited, avoiding the abrasive belt from detaching from the mounting seat 4 and the polishing abutting block 5, and ensuring that the abrasive belt can perform normal polishing operations.

[0025] In this embodiment, the guiding sheet metal part 12 is arranged in a ring shape, and the guiding sheet metal part 12 is provided with an opening for the side wall of the working rack 2 to be inserted. After the side wall of the working rack 2 is connected to the inner wall of the guiding sheet metal part 12, two groups of abrasive belts for entering and leaving the polishing operation position are formed for passing through. The above shape and structure of the sheet metal part are simple in structure and convenient for installation.
