[0002] A drilling and tapping machine is a mechanical device used for drilling and tapping. It is commonly used in metal processing and manufacturing. Ordinary drilling and tapping machines generally include a drilling and tapping machine head, a base and a clamping table. When working, the workpiece is positioned and clamped on the clamping table, and then the drilling and tapping machine head moves along the feed direction to operate. Drilling is to leave a cylindrical hole or hole on the target object, and tapping is to process the internal thread of the workpiece.

[0003] The workpiece vises commonly used in drilling and tapping machines on the market can generally only clamp the root of the workpiece to be processed before processing. When processing workpieces of different heights, since the workpiece vise only clamps the root of the workpiece, there will be a certain loss when the holding force is transmitted to the top of the workpiece, causing the top of the workpiece to loosen or shake during processing, which in turn leads to increased vibration and errors in the processing process, affecting the processing quality.

[0004] Therefore, in view of the above problems, a workpiece vise for a drilling and tapping machine is proposed. Utility Model Content
