Description

Drilling machine and laser device positioning structure

This creation is a drilling machine and its laser device positioning structure, especially a laser optical auxiliary positioning device that should be used in vertical drilling machines or electric drills. The laser projects the surface beam to form a converging light spot to be drilled The processing object of the hole indicates the processing point of the drill bit of the drilling machine.

Press, the drilling machine tool uses the drill bit as the axis, after high-speed operation, take a bit to drill a hole of a certain size on the object to be processed. When an operator drills a hole, the drilling point of the drill bit is usually visually aligned with the center hole of the processed object, which often results in an inaccurate drilling point offset. In addition to the need to repeatedly adjust the processed object, it takes time , May also cause unnecessary holes and damage the processed objects.

Therefore, when drilling a machine such as a drilling machine for hole processing, it is generally necessary to first line the workpiece to be processed, then punch the center hole with a punch, and then start the drilling hole processing equipment for trial drilling, and then adjust the workpiece. position. Calibration is repeated until the trial drilling and the center hole punched are consistent. In this process, the trial drilling and the adjustment of the position of the workpiece to be processed are often repeated many times. The adjustment process is time-consuming and labor-intensive, which easily causes operator fatigue, and it is difficult to ensure the accuracy of the hole position.
