[0021] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0022] Implementation Method 1

[0023] like Figures 1 to 4 As shown, this utility model includes a heightening block 1, a positioning block 2, a mechanical quick clamp 3, a pressure block 4, urethane rubber 5, a slider 7, and a guide rail 8. The heightening block 1 has several mounting holes or slots for securely fixing this utility model to the polishing machine table, and its height can be adjusted as needed. The positioning block 2 is detachably mounted on the heightening block 1 by screws or fasteners. The positioning block 2 has at least one retaining edge 21, the height of which is adapted to or slightly higher than the thickness of the product 6 to be polished, so that the product 6 does not shake or shift during the polishing process.

[0024] The mechanical quick clamp 3 is connected to the pressure block 4 and includes clamping arms and linkage mechanisms. It allows the operator to quickly clamp or release the pressure block 4 by performing simple handle or mechanism operations. The side of the pressure block 4 facing the product 6 to be polished is covered with urethane adhesive 5. The thickness and material of the urethane adhesive 5 can be selected according to the hardness and surface precision requirements of the workpiece, thereby reducing surface damage or pressure marks during clamping.

[0025] The slider 7 is fixed to the pressure block 4 by screws or other fastening methods, and can slide along the guide rail 8 to achieve fine adjustment of the position of the product 6 to be polished and precise control of the clamping force direction. When the operator releases the mechanical quick clamp 3, the slider 7 drives the pressure block 4 to move away from the positioning block 2, forming sufficient loading or unloading space, so that the product 6 to be polished can be quickly changed or automatically loaded and unloaded.

[0026] During use, first, fix the heightening block 1 in the appropriate position on the polishing machine and make fine adjustments for different workpiece heights. The operator places the product 6 to be polished on the positioning block 2, ensuring one side is flush against the retaining edge 21. At this point, the side of the product 6 to be polished is positioned at the reference point. Next, the operator moves the pressure block 4 towards the positioning block 2 using the operating handle or mechanism of the mechanical quick clamp 3. The urethane adhesive 5 will then adhere tightly to the product 6 to be polished, achieving safe and stable clamping. Subsequently, the polishing machine can be started to polish the workpiece surface. After polishing, the mechanical quick clamp 3 can be released to remove the workpiece. To further improve positioning accuracy or add a foolproof function, positioning pins or positioning grooves can be added to the positioning block 2 or pressure block 4 to prevent the workpiece from shifting or being scratched due to incorrect assembly orientation.

[0027] Implementation Method Two (Optional)

[0028] While meeting basic clamping and protection requirements, the following improvements or extensions can be made according to different application scenarios:

[0029] 1. If it is necessary to accommodate larger or thicker workpieces, the overall height can be adjusted by adding shims between the heightening block 1 and the positioning block 2 or by using multiple layers of heightening blocks 1, so that the surface of the product 6 to be polished can be better matched with the working area of ​​the polishing machine.

[0030] 2. If higher positioning accuracy is required, a fine-tuning structure (such as an adjustable screw) can be added to the retaining edge 21 to make minor corrections to the position of the product 6 to be polished.

[0031] 3. If production needs frequently involve changing workpieces of different shapes or sizes, various specifications of positioning blocks 2 and pressure blocks 4 can be prepared in advance, allowing operators to complete the fixture modification in a short time.

[0032] In summary, this utility model, through the combination of a retaining edge 21 and urethane adhesive 5 in a quick-clamping structure, achieves efficient positioning and stable clamping of various planar workpieces, while effectively reducing the probability of surface damage. The heightening block 1 ensures rapid adaptation to different machine tools or workpiece thicknesses. The mechanical quick clamp 3 improves clamping efficiency and simplifies loading and unloading operations. Compared with existing technologies, this utility model has a simple structure, convenient operation, accurate positioning, and good protective effect, and can be widely applied in batch or multi-variety production processes of machining and surface treatment. Any equivalent substitutions or modifications made by those skilled in the art to the specific structure or materials without departing from the concept of this utility model are within the protection scope of this utility model.

[0033] The embodiments described herein are preferred embodiments of this utility model and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape, and principle of this utility model should be included within the scope of protection of this utility model.
