Description

But rotation angle's tuber pipe drilling frock

Technical Field

The invention relates to the field of air pipe machining, in particular to an air pipe drilling tool capable of rotating by an angle.

Background

At present, in the actual production process on site, the accuracy of the hole site angle on the air pipe plays a crucial role in cooling the mold, but no better method is available for drilling the air pipe. At present, workers are mainly used for firstly scribing lines at specific angles of the air pipes by using an angle ruler, then the workers step on the air pipes by feet, and the workers are used for drilling the required air holes by using hand drills. The drilling method adopts manual angle scribing, the positions of the angle scribing by different people are different, so that the angle of the drilled air hole has larger deviation sometimes, and the quality and the size of the drilled air hole are different by manually drilling the air hole, so that the phenomenon of drilling skew is easy to occur. Moreover, workers step on the air pipe by feet and drill air holes by a manual drill, so that great potential safety hazards exist, and once the workers are careless or are collided by other people, the workers are easy to cause industrial injuries. If the fall causes no industrial injury, the worker squats for a long time to drill, and the labor intensity of the worker is very high.
