Description

Technical Field

[0001] This utility model relates to the technical field of grinding and polishing equipment, and more particularly to a workpiece clamping device. Background Technology

[0002] Workpiece clamping devices are an indispensable and important device in the machining process. They are used to fix the workpiece and keep it in the correct position and posture during machining to ensure machining accuracy and safety.

[0003] However, the workpiece clamping devices commonly found on the market have relatively complex structures, using many custom parts to form a whole. The production of custom parts requires the separate design and manufacture of molds, making the price of custom parts much higher than that of standard parts. Moreover, custom parts do not have sufficient inventory or can be quickly procured like standard parts. Once the equipment malfunctions and custom parts need to be replaced, consumers may have to wait a long time for the equipment to return to normal use. Therefore, further improvements to the existing technology are necessary. Utility Model Content
