Description

Technical Field

[0001] The utility model relates to the technical field of magnetic drill presses, in particular to a magnetic drill press capable of rapid positioning. Background Art

[0002] A magnetic drill press adsorbs on a steel plate through an electromagnet on its base to achieve rapid positioning for drilling. It has the advantages of being convenient to move and easy to adjust the drilling position. For example, in the prior art, a patent document with the publication number CN220920989U discloses a rotatable magnetic drill press, which includes a magnetic drill press body and a magnetic block. An adjusting mechanism is arranged between the magnetic drill press body and the magnetic block, and the adjusting mechanism is used to adjust the angle of the magnetic drill press body on the surface of the magnetic block. The utility model relates to the technical field of magnetic drill presses. In this rotatable magnetic drill press, an adjusting block is arranged between the magnetic drill press body and the magnetic block. The surface of the adjusting block is fixedly connected to the surface of the magnetic block and rotatably connected to the surface of the magnetic drill press body. Thus, the position of the magnetic drill press body relative to the magnetic block can be rotated and changed. An operating gear and an acting gear that rotate are arranged inside the adjusting block, and the angle of the magnetic drill press body is changed through the gears. Moreover, the angle is changed by the action of the operating gear, which is convenient for position adjustment. A scale disk is arranged at the position of the operating gear, which can intuitively reflect the rotation angle of the magnetic drill press body and is more convenient for adjustment.

[0003] In the actual use process, since the magnetic drill press can only adsorb on the steel plate and drill vertically downward along the surface of the steel plate, in many cases, the surface of the drilling area is narrow, and the magnetic suction base of the magnetic drill press cannot be firmly adsorbed on this narrow surface. We need to change the adsorption position, adjust the drill bit angle, and then drill in this drilling area. However, the drilling direction of the existing magnetic drill press is fixed and cannot be adjusted, so its use is not flexible enough and needs to be further improved. Summary of the Utility Model
