The radial drilling machine that is easy to position, by setting an adjustment component and a threaded part, when clamping a smaller workpiece, the adjustment component can be operated to drive the threaded part to move so that the two threaded parts are away from the stud, and at this time, the distance between the clamp seat and the side clamping plate can be quickly adjusted to fit the workpiece, so that the device can meet the positioning of workpieces with a large clamping span according to actual needs, avoiding the need to rotate the stud multiple times to achieve clamping, which causes inconvenience in operation, making the radial drilling machine simpler and faster to position the workpiece.

[0004] Existing drilling machines adjust the distance between the clamp and the side clamp to make it fit on the workpiece. However, for some special-shaped workpieces, such as arc-shaped workpieces, the effective contact surface of the clamp may be only a line, which leads to insufficient clamping area and inability to effectively clamp and fix the workpiece. In this case, the workpiece may move or shake during the processing, affecting the processing accuracy and quality. Therefore, there is a problem of inconvenience in effectively clamping the workpiece. Utility Model Content
