Description

Technical Field

[0001] This utility model relates to the field of positioning and clamping technology, specifically to a workpiece clamping and positioning device. Background Technology

[0002] In the manufacturing process of mechanical devices, the assembly and manufacturing of multiple precision parts or structures are usually involved. Current clamping devices are not good at adapting to workpieces. Once the workpiece size changes, it is necessary to customize or replace the clamping device, which undoubtedly increases manufacturing costs for applications that require large-scale use.

[0003] Existing clamping devices for electrical equipment can only perform basic workpiece clamping functions and lack a pre-positioning step designed for workpieces of specific specifications. This means that if the workpiece's position changes during clamping, the fixture must be adjusted accordingly to ensure correct clamping. This process is not only time-consuming but also reduces overall work efficiency. Therefore, developing a clamping device that can pre-position and then clamp, and has better versatility, is particularly important. It can significantly reduce adjustment time and improve production efficiency while ensuring clamping accuracy. Utility Model Content
