A pipe round hole chamfering equipment

Abstract

The invention discloses pipe round hole chamfering equipment and aims at providing pipe round hole chamfering equipment simple in structure, low in manufacturing cost, capable of facilitating machining and capable of effectively guaranteeing the chamfering uniformity of radial round holes in the peripheral face of a pipe. The pipe round hole chamfering equipment comprises a rack, a round hole positioning mechanism, a pipe installing mechanism, a linkage type forward direction pipe drive mechanism, vertical guide columns arranged on the rack, an upper installing flat plate, a lower installing flat plate, a connecting structure, a lifting executing mechanism and a vertical chamfering cutter, wherein the upper installing flat plate and the lower installing flat plate ascend and descend along the vertical guide columns, the connecting structure connects the upper installing flat plate with the lower installing flat plate, the lifting executing mechanism is arranged on the rack and used for ascending and descending of the upper installing flat plate, and the vertical chamfering cutter is rotationally arranged on the lower installing flat plate. The pipe installing mechanism comprises a horizontal installing shaft sleeve rotationally arranged on the rack through a horizontal rotation shaft. The linkage type forward direction pipe drive mechanism comprises a forward gear, a reverse gear, a first vertical drive rod and a second vertical drive rod, wherein the forward gear and the reverse gear are arranged on the horizontal rotation shaft, and the first vertical drive rod and the second vertical drive rod are arranged on the upper installing flat plate.

Description

technical field [0001] The invention relates to the field of pipe processing, in particular to a pipe round hole chamfering equipment. Background technique [0002] At present, the chamfering method of the outer port of the radial round hole (the radial round hole refers to the round hole whose axis extends radially along the pipe) on the outer peripheral surface of the pipe (the pipe in the text refers to the round pipe) usually adopts the plane round hole The chamfering method is used to chamfer, that is, use the chamfering knife to extend into the radial circular hole, and chamfer the outer port of the radial circular hole through the rotation of the chamfering. Such as Figure 4 As shown, since the outer peripheral surface of the pipe 6 is a cylindrical surface, the outer port edge of the radial circular hole 6.1 on the outer peripheral surface of the pipe is not in a plane, and the chamfering knife is inserted into the radial circular hole on the outer peripheral surfac...

AI Technical Summary

Problems solved by technology

like Figure 4 As shown, since the outer peripheral surface of the pipe 6 is a cylindrical surface, the outer port edge of the radial circular hole 6.1 on the outer peripheral surface of the pipe is not in a plane, and the chamfering knife is inserted into the radial circular hole on the outer peripheral surface of the pipe for chamfering , the cutting amount of the chamfering knife on the outer port edge of the radial hole on the outer peripheral surface of the pipe is inconsistent, the cutting amount of the chamfering knife on the high point of the outer port edge of the radial hole is the largest, and the cutting amount of the outer port edge on the outer peripheral surface of the pipe is the largest The cutting amount at the low position of the outer port edge of the round hole is the smallest, resulting in poor chamfering uniformity of the radial round hole on the outer peripheral surface of the pipe
