Description

Technical Field

[0002] A drilling machine is a machine tool that mainly uses a drill to make holes on a workpiece. Usually, the rotation of the drill is the main motion, and the axial movement of the drill is the feed motion. The drilling machine has a simple structure and relatively low processing accuracy. It can drill through holes and blind holes. By replacing special tools, it can expand, countersink, ream holes or perform tapping and other processing. During the processing, the workpiece does not move, the tool moves, aligns the center of the tool with the center of the hole, and rotates the tool (main motion). The characteristic of a drilling machine is that the workpiece is fixed and the tool rotates.

[0003] In the related art, before processing a workpiece by a drilling machine, the workpiece needs to be clamped and limited on the top of the drilling machine. However, some existing drilling machines have relatively simple functions and are not convenient for fixing workpieces of different sizes. At the same time, when the heights on both sides of the workpiece are inconsistent, some existing devices cannot effectively fix the workpiece, which causes the workpiece to easily shift in position during the processing, thereby greatly reducing the processing quality of the workpiece.

[0004] Therefore, it is necessary to provide a drilling machine with stable clamping to solve the above technical problems. Utility Model Content
