Technical Field

[0001] The utility model relates to the field of drilling machine clamps, in particular to a clamp for a numerically controlled drilling machine. Background Art

[0002] A drilling machine is a machine tool that mainly uses a drill to drill 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. During the processing, the workpiece does not move, and the tool moves to align the center of the tool with the center of the hole, and the tool rotates (main motion). The characteristic of a drilling machine is that the workpiece is fixed and the tool rotates.

[0003] When the drilling machine is in use, the workpiece needs to be fixed and installed to maintain the stability of the workpiece and prevent the workpiece from shaking during drilling, causing the drilling to deviate.

[0004] Referring to the existing Chinese patent with publication number CN108907804A, a double clamp device for CNC drilling machine equipment is disclosed, which includes a box body, the lower surface of the box body is fixedly connected with four support legs, and the four support legs are respectively located at the four corners of the lower surface of the box body, the lower surface of the inner wall of the box body is provided with a slide groove, two first fixed plates are arranged in the box body, and the upper surface and lower surface of the two first fixed plates are respectively fixedly connected with the upper surface of the inner wall of the box body and the lower surface of the inner wall of the slide groove, and the opposite surfaces of the two first fixed plates are clamped with first bearings. The double clamp device for CNC drilling machine equipment can adjust the distance between the two clamps through the mutual cooperation between the motor, the first bevel gear, the second bevel gear, the first rotating shaft, the first bearing, the first fixed plate, the first threaded column, the first threaded cap, the second rotating shaft, the second bearing, the slider, the fixed block, the through hole and the support plate, so as to bring convenience to the work of the staff.
