A chamfering machine

Abstract

The invention discloses a chamfering machine and aims to provide the chamfering machine which can effectively ensure the chamfering uniformity of a radial circular hole in the peripheral surface of a pipe and can effectively avoid the problem that the pipe is scrapped because a vertical rose reamer cut off the pipe out of the radial circular hole. The chamfering machine comprises a rack, a circular hole positioning mechanism, a pipe mounting mechanism, a linkage type forward and reverse pipe driving mechanism, a rotating shaft limiting mechanism, a vertical guide column arranged on the rack, an upper mounting plate and a lower mounting plate capable of going up and down along the vertical guide column, and a vertical rose reamer rotatably arranged on the lower mounting plate; the pipe mounting mechanism comprises a horizontal mounting shaft sleeve rotatably arranged on the rack through a horizontal rotating shaft; the linkage type forward and reverse pipe driving mechanism comprises a drive gear arranged on the horizontal rotating shaft and a first vertical drive rod and a second vertical drive rod arranged on the upper mounting plate; and the rotating shaft limiting mechanism comprises a vertical limiting rod positioned below the horizontal rotating shaft and a limiting hole in the outer side face of the horizontal rotating shaft.

Description

technical field [0001] The invention relates to a chamfering machine, in particular to a pipe chamfering machine. 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 5 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 cha...

AI Technical Summary

Problems solved by technology

[0004] When the upper mounting plate lifting actuator drives the upper mounting plate to move down, and before the first gear rack meshes with the driving gear, the pipe installed in the horizontal mounting sleeve will rotate; especially, when the vertical chamfering knife will touch the At the outer port of the radial circular hole on the outer peripheral surface of the pipe, the pipe installed in the horizontal installation sleeve will rotate; and before the first rack is meshed with the driving gear, the pipe installed in the horizontal installation sleeve will rotate Rotate, so that the initial position of the pipe installed in the horizontal installation bushing changes, in the process of the first rack and the forward gear meshing to drive the pipe and the process of the second rack and the reverse gear meshing to drive the pipe, there will be The problem that the vertical chamfering knife cuts off the pipe outside the radial circular hole, resulting in the scrapping of the pipe
