However, the existing method of fixing the grinding wheel is cumbersome, which makes the disassembly of the sanding belt difficult. This not only affects the processing efficiency of metal products, but also increases the labor intensity of the operators. Utility Model Content

Detailed Implementation

[0015] Without altering the essential spirit of this utility model, those skilled in the art can propose various interchangeable structural methods and implementations for the technical solution of this utility model. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model and should not be considered as the entirety of this utility model or as limitations or restrictions on the technical solution of this utility model.

[0016] Reference Figures 1-4 As shown, this utility model provides a technical solution: a polishing device for metal product processing, including a base plate 1; a mounting frame 2 is fixed to the top of the base plate 1, and T-shaped brackets 3 are provided on the top of both the base plate 1 and the mounting frame 2. The T-shaped brackets 3 are placed opposite each other, and a polishing assembly is provided on one side of the T-shaped bracket 3. The polishing assembly includes a first grinding wheel 4 and a motor 5. There are two first grinding wheels 4. The motor 5 is installed at the rear end of the mounting frame 2, and the output end of the motor 5 is fixed to the rear end of the first grinding wheel 4. A guide rod 6 is fixed to one side of the T-shaped bracket 3, and a slide seat 7 slides on the surface of the guide rod 6. A second grinding wheel 8 is fixed to one side of the slide seat 7. The surfaces of the first grinding wheel 4 and the second grinding wheel 8 are provided with sanding belts 9. A connecting rod 10 is fixed to one side of the slide 7. The connecting rod 10 passes through the T-shaped bracket 3 and extends to the outside of the T-shaped bracket 3. A housing 11 is fixed to one side of the T-shaped bracket 3. A fixing mechanism for fixing the connecting rod 10 is provided inside the housing 11. The connecting rod 10 can be quickly fixed and unlocked by the fixing mechanism. Then the position of the second grinding wheel 8 can be moved so that the sanding belt 9 is in a relaxed state, which makes it easy to replace the sanding belt 9 and also easy to install the sanding belt 9. This solves the problem of difficult disassembly of the sanding belt 9 in the prior art, which affects the processing efficiency of metal products.

[0017] Reference Figure 4As shown, in this embodiment: the fixing mechanism includes a handle 12 threaded to the side wall of the housing 11. A pressing block 13 is fixed to one end of the handle 12 inside the housing 11. A pressure plate 14 slides inside the housing 11, located at one end of the pressing block 13. A fixing pin 15 is fixed to one side of the pressure plate 14. Two fixing grooves 16 matching the fixing pins 15 are formed on the surface of the connecting rod 10. Springs 17 are fixed to both ends of one side of the pressure plate 14. The other end of the springs 17 is fixed to the inside of the housing 11. Specifically, by rotating the handle 12... 2. The extrusion block 13 is rotated. When the extrusion block 13 rotates to a horizontal position, it will move away from the pressure plate 14. At this time, the pressure plate 14 will be pushed by the rebound force of the spring 17. The force will cause the fixing pin 15 to disengage from the fixing groove 16. At this time, the operator can move the connecting rod 10. The connecting rod 10 drives the slide 7 to slide on the surface of the guide rod 6. The slide 7 drives the second grinding wheel 8 to move until the sanding belt 9 is in a relaxed state. The operator can then remove the sanding belt 9 for replacement. After the replacement is completed, the above steps are reversed to achieve quick installation of the sanding belt 9. The operation is simple and quick, which greatly improves the processing efficiency of metal products.

[0018] Reference Figure 4 As shown in this embodiment, the extrusion block 13 is elliptical in shape. Through the elliptical design, the extrusion block 13 can achieve the extrusion and release of the pressure plate 14 by switching between the major axis and the minor axis. Compared with the traditional cylindrical or square structure, the elliptical extrusion block 13 can transmit the force more smoothly and reduce operation jamming.

[0019] Reference Figure 4 As shown in this embodiment: Limiting rods 18 are fixed on both sides inside the housing 11, and limiting grooves 19 matching the limiting rods 18 are opened at both ends of the pressure plate 14. The limiting rods 18 and the limiting grooves 19 limit the pressure plate 14, preventing the pressure plate 14 from shifting during movement and ensuring the stability of the movement of the pressure plate 14.

[0020] Reference Figure 4 As shown in this embodiment: an anti-slip pad 20 is fitted on the surface of the long shaft end of the handle 12. The two sides of the anti-slip pad 20 abut against the opposite surfaces of the housing 11 and the handle 12, respectively. The anti-slip pad 20 increases the friction between the handle 12 and the operator's hand, preventing the operator from slipping when turning the handle 12, thus ensuring the safety of operation. At the same time, the anti-slip pad 20 is made of soft material, which improves the comfort of the operator when using it.

[0021] Reference Figure 4As shown in this embodiment: the rear end of the slide block 7 is provided with a guide groove 21. The slide block 7 is slidably installed on the front end of the guide rod 6 through the guide groove 21. Through the cooperation between the guide groove 21 and the guide rod 6, the slide block 7 is guided, making the slide block 7 more stable during movement, avoiding the phenomenon of the slide block 7 shaking or deviating, and ensuring the stability of the polishing device operation.

[0022] Working Principle: The user can quickly fix and unlock the connecting rod 10 using the fixing mechanism, and then move the position of the second grinding wheel 8 to loosen the sanding belt 9, thus facilitating its replacement and installation. This solves the problem of difficult disassembly of the sanding belt 9 in existing technologies, which affects the processing efficiency of metal products. Specifically, by rotating the handle 12, the extrusion block 13 rotates. When the extrusion block 13 rotates to a horizontal position, it moves away from the pressure plate 14. At this time, the pressure plate 14 is pushed by the rebound force of the spring 17, causing the fixing pin 15 to disengage from the fixing groove 16. The operator can then move the connecting rod 10, which causes the slide 7 to slide on the surface of the guide rod 6. The slide 7 moves the second grinding wheel 8 until the sanding belt 9 is loosened, at which point the operator can remove the sanding belt 9 for replacement. After replacement, the above steps are reversed to achieve quick installation of the sanding belt 9. The operation is simple and fast, greatly improving the efficiency of metal product processing. In terms of processing efficiency, the elliptical design of the extrusion block 13 allows for the extrusion and release of the pressure plate 14 by switching between its long and short axes. Compared to traditional cylindrical or square structures, the elliptical extrusion block 13 can transmit force more smoothly, reducing operational jamming. The limiting rod 18 and limiting groove 19 limit the pressure plate 14, preventing it from shifting during movement and ensuring its stability. The anti-slip pad 20 increases the friction between the handle 12 and the operator's hand, preventing slippage and ensuring operational safety. The anti-slip pad 20, made of soft material, enhances operator comfort. The guide groove 21, in conjunction with the guide rod 6, guides the slide 7, making its movement more stable and preventing wobbling or shifting, thus ensuring the stability of the polishing device.

[0023] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
