Description

Technical Field

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

[0002] Clamping in machining refers to the use of various clamping devices to fix the workpiece on a workbench or machine tool in order to maintain the stability and accuracy of the workpiece during the machining process. Clamping plays a vital role in machining, ensuring that the workpiece does not move or deform during the machining process, thereby ensuring machining accuracy and quality.

[0003] However, the existing clamping device is usually installed on the top of the workbench. Both the screw and the tooth plate will take up a lot of space on the workbench. In a relatively small working space, this will limit the worker's field of vision, which is not conducive to the worker's observation of the workpiece during processing. In addition, most of the existing equipment only clamps the workpiece in the horizontal direction, and the clamping effect can be further improved. Utility Model Content
