Description

But rotation angle's tuber pipe drilling frock

Technical Field

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

Background

At present, in the actual production process on site, the accuracy of the hole position angle on the air pipe plays a crucial role in cooling the mould, but no better method for drilling the air pipe exists. At present, a worker firstly uses an angle ruler to scribe lines at a specific angle of the air duct, then uses feet to tread the air duct, and uses hand drill to drill the required air hole. According to the drilling method, because manual scribing is adopted, the positions of the scribing lines of different angles are different, so that the angle of the drilled wind hole is sometimes greatly deviated, and the quality of the drilled wind hole is poor and the drilling distortion phenomenon is very easy to occur due to the fact that the wind holes are drilled manually. In addition, the worker steps on the air pipe by foot and drills the air hole by hand, so that the safety hazard is large, and once the worker is careless or is touched by others, the worker is extremely easy to hurt. If the lucky is not damaged by work, the lucky is crouched on the ground for a long time to drill holes, and the labor intensity of workers is very high.
