Description

Technical Field

[0001] The utility model relates to the technical field of clamps, in particular to a clamp for smoothing processing. Background Art

[0002] Polishing is commonly used in the processing and manufacturing of metals, plastics, ceramics and other materials. It is suitable for various industrial fields such as automobile manufacturing, aerospace, electronic equipment, jewelry processing, etc.

[0003] Polishing is a surface treatment process used to improve the smoothness and glossiness of the material surface. During the polishing process, abrasives and grinding tools are usually used to grind and polish the workpiece surface to remove surface unevenness and defects, so as to obtain a smooth, uniform and shiny surface. Its main purposes include: improving surface quality: removing the unevenness, defects and oxide layer on the workpiece surface to make the surface smoother and flatter; improving appearance quality: making the workpiece surface have good gloss and appearance, enhancing the beauty and quality of the product; improving functionality: improving the friction performance, corrosion resistance and wear resistance of the surface, and improving the service life and performance stability of the workpiece. Polishing usually involves multiple steps, including rough grinding, medium grinding and fine grinding. Abrasives of different particle sizes and shapes are used in each stage to gradually improve the surface quality. During the processing, polishing agents and polishing tools may also be used to perform the final polishing of the surface to achieve the required smoothness and glossiness. Therefore, during the polishing process, the workpiece needs to be stably clamped by a special fixture to ensure the stability and processing accuracy of the polishing process.

[0004] The utility model patent with application number 202222825709.8 discloses a surface polishing device for stainless steel products. In the technical solution provided by the utility model, the disclosed flip adjustment clamp uses the reaction force of the spring to make the slider rebound and reset to drive the fixed frame to close to clamp and fix the stainless steel product in the middle, and extends the first electric push rod to drive the clamp to close to clamp the stainless steel product firmly. The first motor rotates to drive the fixed frame to rotate, thereby driving the clamped stainless steel product to rotate and flip to adjust the angle, thereby effectively improving the angle adjustment performance of the structure. There is no need to disassemble and reinstall multiple times to adjust the angle. The operation is simple and convenient, and the work efficiency is improved.

[0005] The polishing treatment of the stainless steel surface is also called smoothing treatment in this field, which aims to grind the surface of the stainless steel product to the surface roughness required by the actual requirements. In the technical solution disclosed in the above utility model patent, the flip adjustment clamp drives the clamp plate to slide and open by contracting the first electric push rod, and the stainless steel product is placed between the fixed brackets. The reaction force of the spring causes the slider to rebound and reset to drive the fixed bracket to close, thereby clamping and fixing the stainless steel product in the middle. However, this clamping method that relies on the reaction force of the spring cannot stably clamp the stainless steel product. The gravity of the stainless steel product itself and the complex stress conditions during the processing may cause the stainless steel product to fall out of the fixed bracket and cause accidents and economic losses. At the same time, in the fixing method disclosed in the above utility model patent, the fixed plate provided therein directly clamps the surface of the product, and there is a lack of buffering measures between the fixed plate and the product, which is also easy to cause damage to the surface of the stainless steel product and affect the product yield.
