Description

Technical Field

[0001] The utility model relates to the technical field of CNC processing, in particular to a quick workpiece clamping device. Background Art

[0002] CNC, also known as computer gong, CNCCH or numerically controlled machine tools, is actually a CNC milling machine. Its main job is to compile processing programs, that is, to convert the original manual work into computer programming. Generally, CNC processing usually refers to computer digital control of precision machining, CNC lathes, CNC milling machines, CNC boring and milling machines, etc.

[0003] For workpieces that cannot be processed on a vacuum table, the traditional clamping method generally uses glue or flat-nose pliers. However, when using glue, the workpiece needs to wait for the glue to dry before it can be processed, which takes a long time. After the workpiece is processed, it is difficult to remove the workpiece and it is easy to damage the workpiece. The flat-nose pliers method is only suitable for clamping small workpieces. Large workpieces cannot be clamped and it is difficult to calibrate the level. Utility Model Content
