Description

Technical Field

[0001] The utility model relates to the technical field of surface grinder equipment, in particular to a positioning mechanism for a surface grinder. Background Art

[0002] A surface grinder is a mechanical device used to process flat surfaces. Its main uses include precision grinding, flattening and surface shaping of metal and non-metal materials. Its main advantage is that it can provide high-precision surface processing and repeatability, and can meet the processing requirements with strict requirements on the flatness, verticality and finish of the workpiece. Through automatic control and advanced feeding systems, surface grinders can achieve high-efficiency batch processing and complex shape processing requirements. During the operation of the surface grinder, a positioning mechanism is required to clamp and fix the grinding parts.

[0003] The positioning mechanism of the surface grinder is a key mechanical device used to ensure the precise positioning and motion control of the workpiece and the grinding wheel during the grinding process. The surface grinder positioning mechanism is widely used in the precision machining process in the manufacturing industry, especially for workpieces with high requirements for plane and surface accuracy. In short, the surface grinder positioning mechanism is a vital part of modern manufacturing. It ensures high precision and high efficiency in the workpiece machining process through precise position control and motion trajectory management.

It is difficult to adjust the positioning mechanism according to the needs of different circular workpieces. In the process of grinding large quantities of cylindrical workpieces, the processing efficiency is reduced and the grinding time is prolonged. Therefore, a surface grinder positioning mechanism is proposed to solve the above problems. Utility Model Content

[0034] Specifically, in the working process of the surface grinder positioning mechanism, first, the motor 4 is connected to the disc 15 through its output end to enable it to rotate, thereby driving the L-shaped connecting plate 7 to rotate through the connecting bar 1, and the rotation of the L-shaped connecting plate 7 drives the connecting block 19 to move through the connecting bar 2 8, so that the slider 2 10 can move inside the connecting disc 2 13, and finally drives the L-shaped clamping plate 11 to move to the outer wall of the circular workpiece, so that no matter how the size of the workpiece changes, it can be effectively clamped and fixed to ensure processing accuracy and stability. Overall, this surface grinder positioning mechanism has significantly improved clamping efficiency and processing accuracy, and provides reliable guarantee for the fine processing of workpieces.
