TECHNICAL FIELD
[0001] The utility model belongs to the technical field of machining equipment, and particularly relates to a multifunctional drilling machine integrating drilling, chamfering and tapping. BACKGROUND
[0002] Flange connection is a common connection mode of metal pipelines, such as straight-through joints, three-way joints, elbow joints and other metal pipeline connection components, which are generally produced in the form of castings. The two ends of the connection components are generally integrally cast with flange parts. Flange connection is usually fastened by screws, so the edges of the flange parts generally need to be drilled with screw holes for mounting the screws. Some screw holes further need to be chamfered on the hole edges, and even some screw holes need to be tapped into threaded holes. In addition, according to actual conditions, the flange part may need to be uniformly arranged with a ring of screw holes, or only two symmetrical screw holes may be needed. During the processing of threaded holes, a relatively thin drill is usually used to first drill a hole, then a relatively thick drill is used to expand the hole, then a thicker drill is used to chamfer the hole, and finally a tap is used to tap the hole. The traditional drilling machine can only install one drill or tap at a time, and multiple drilling machines are needed for multiple processes of processing threaded holes, which requires high equipment investment. However, only one drilling machine needs to frequently change different specifications of drills and taps, which is very troublesome to operate and seriously affects production efficiency.
