[0002] A surface grinder is a device that uses a grinding wheel to rotate and grind workpieces to achieve a certain degree of flatness. It is widely used in the mechanical processing industry. When using a surface grinder to grind mechanical parts, a fixture is required to clamp and guide the parts to be grinded.

[0003] The current surface grinder fixture device, such as the "A Surface Grinder Fixture Device" proposed in patent number 202321375060.2, includes a base, a groove is provided in the middle of the base, and at least one lifting structure is provided in the inner cavity of the groove, and the lifting structure includes a hydraulic rod 1 fixedly connected to the bottom of the inner cavity of the groove, and the top of the hydraulic rod 1 is fixedly connected to a U-shaped frame, and the tops of both ends of the U-shaped frame are fixedly connected to support plates, and both ends of the top of the base are fixedly connected to a clamping structure. The surface grinder fixture device, through the setting of the rotating structure, the deflection angle between the fixed block and the rotating block can be changed, so that the clamp in the device can clamp rectangular workpieces and circular workpieces at the same time, improving the practicality of the clamping structure, and the clamp can clamp circular workpieces of various diameters, improving the adaptability of the clamp, reducing the frequency of replacing the clamp during the use of the device, and indirectly improving the working efficiency of the device.

[0004] The existing surface grinder fixture device arranges rotating blocks on both sides of the clamping plate to make the clamping plate as a whole straight or curved arc-shaped clamping plate. Although it can adapt to the purpose of processing parts with different appearances, in actual use, when processing and grinding mechanical parts, if there is a need to grind some of its side ends or other positions, the workpiece needs to be removed from the clamping mechanism and then repositioned for installation and limiting. Repeating this process is time-consuming and affects the processing efficiency to a certain extent. Therefore, there is an urgent need to improve the technology of the surface grinder fixture device structure to improve this equipment. Utility Model Content
