Mechanical parts are the basis for researching and designing various types of machinery, as well as the basis for manufacturing and repairing machinery. During the processing of mechanical parts, they need to be polished, which usually includes cylinders, polishing motors and polishing discs. The polishing motor and polishing disc are driven up and down by the telescopic rod of the cylinder to polish the parts. In general, the mechanical parts processing and polishing device is one of the indispensable equipment in the field of mechanical processing, and plays an important role in improving the surface quality, processing efficiency and product quality of mechanical parts.

[0003] Existing grinding devices usually use one-way fixed clamping when processing parts. Since the parts need to be polished from different sides, manual cooperation with the machine is required to re-fix and clamp them when grinding different sides, which reduces the processing efficiency. In addition, during this process, the parts may be offset or tilted, resulting in the processed size and shape not meeting the design requirements, thus affecting the processing accuracy.

A mechanical parts processing and grinding device can be designed to adopt a flexibly adjustable clamping structure to improve the efficiency and accuracy of parts grinding. Utility Model Content

Through the flexibly adjustable clamping structure, it can be ensured that the mechanical parts maintain a stable position and posture during the processing process, thereby greatly improving the accuracy of the processing, which is especially important for the processing of mechanical parts requiring high precision. At the same time, the workpiece can be clamped quickly and accurately to achieve rapid fixation of the workpiece, reducing the time required for changing and adjusting the clamping method, thereby improving production efficiency, in order to solve the problem that the existing grinding device usually adopts one-way fixed clamping. Since the parts need to be ground from different sides, manual cooperation with the machine is required to re-fix and clamp them during adjustment, which may reduce the processing efficiency and affect the processing accuracy.
