Description

Technical Field

[0001] This utility model relates to the field of metal parts processing technology, specifically a rapid clamping device for CNC machining of metal parts. Background Technology

[0002] CNC (Computer Numerical Control Machine Tool) is a common name for computer-controlled automated machine tools. It is an automated device that operates according to a program. In the processing of metal workpieces, if operations such as drilling and trimming are required, CNC machine tools must be used. In addition, since the workpiece needs to be fixed during the processing in order to perform precise operations, CNC machine tools need to be equipped with relevant clamping devices.

[0003] When machining metal parts using CNC machine tools, we usually first mount the metal parts to be machined onto a chuck, which then drives and fixes them to the machine tool spindle. However, since the sizes and shapes of various metal parts are not the same, if only a general three-jaw or four-jaw chuck is used to clamp the workpiece, it may lead to uneven clamping force, which will affect the accuracy of the machined products. In addition, the current equipment height cannot be adjusted, which also limits its application in the machining of metal workpieces.

[0004] Therefore, it is necessary to propose a rapid clamping device for CNC machining of metal parts. Utility Model Content
