Description

Technical Field

[0001] The utility model relates to the technical field of numerical control cutting machines, in particular to a clamping device for a numerical control cutting machine. Background Art

[0002] With the rapid development of the furniture industry, the requirements for mechanical processing of board cutting are getting higher and higher, and the disadvantages of sliding table saws are becoming more and more obvious: insufficient precision, edge collapse, faults, work injuries, low efficiency and other phenomena often occur and plague the development of such enterprises. The birth of CNC cutting machines has effectively avoided the occurrence of such phenomena.

[0003] The clamping device of the cutting machine currently used generally uses bolts and nuts to fix the workpiece. This fixing method is not only troublesome and cumbersome for the workers to operate, but also has low work efficiency. Another method is to extract the air through the suction cup and fix the workpiece by the suction force generated. This fixing method, once the leakage prevention measures are not in place, will cause the firmware to loosen, thereby causing the workpiece to be scrapped when it is operated. Utility Model Content
