Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of plate processing, especially relates to a clamping jaw for plate processing. BACKGROUND

[0002] In the field of laser cutting, hot melt drilling and tapping composite machining, the clamping technology of workpieces is the core link to ensure machining precision and safety. Traditional clamping technology is mainly based on mechanical clamps, electromagnetic chucks and vacuum adsorption schemes, among which mechanical clamps dominate. Such clamps usually use rigid alloy clamps combined with screw transmission or pneumatic drive to apply normal force to the workpiece through multi-point positioning (such as 4-12 clamping points), with a clamping force range of 50N to 20kN and a positioning accuracy of ±0.05mm. Currently, the common technical solution in the industrial processing field is that cutting, drilling and tapping are completed on different equipment stations. This dispersed processing method not only has complex operation, but also has low automation degree. At the same time, as can be seen from the above, the workpiece needs to be re-clamped every time it is transferred to a new equipment station, and the cumulative precision error after multiple clamping is very high, resulting in a low yield in actual production. Therefore, it is best to complete all processes on one equipment, and the clamping of the workpiece needs to be guaranteed at this time.

[0003] Although traditional clamping technology performs stably in basic applications, its inherent defects are particularly prominent in high-precision, multi-process scenarios such as laser cutting, hot melt drilling and tapping composite machines: the direct contact between rigid clamps and workpieces forms a mechanical impedance match, causing machining vibration and conduction to the machine tool. At this time, the workpiece and the machine tool resonate, although the clamps fix the workpiece, but this vibration can still cause the workpiece to displace and cause the machining position to deviate.
