Chamfering method for radial round hole in peripheral surface of round tube

Abstract

The invention discloses a chamfering method for a radial round hole in the peripheral surface of a round tube, and aims a providing a chamfering method which makes machining convenient and also effectively guarantees the chamfering uniformity of the radial round hole in the peripheral surface of the round tube. The chamfering method for the radial round hole in the peripheral surface of the roundtube sequentially includes the following steps that firstly, the round tube is inserted in a horizontal installation shaft sleeve, and the horizontal installation shaft sleeve is rotated to make the radial round hole in the peripheral surface of the round tube face downwards; secondly, a shaft sleeve driving motor drives the round tube to rotate by 180 degrees to make the radial round hole in theperipheral surface of the round tube face upwards; thirdly, a chamfering tool driving motor drives a vertical chamfering tool to rotate, and meanwhile a lifting executing mechanism drives the verticalchamfering tool to descend in place; fourthly, the shaft sleeve driving motor drives the round tube to rotate clockwise by a set angle beta, then the shaft sleeve driving motor stops working, then the shaft sleeve driving motor drives the round tube to rotate anticlockwise by a set angle 2beta, and then the shaft sleeve driving motor stops working.

Description

technical field [0001] The invention relates to the field of machining, in particular to a chamfering method for a radial circular hole on the outer peripheral surface of a circular tube. Background technique [0002] At present, the chamfering method of the outer port of the radial hole on the outer peripheral surface of the round tube (the radial round hole refers to the round hole whose axis extends radially along the round tube) is usually chamfered by the chamfering method of the plane round hole , 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 2 As shown, since the outer peripheral surface of the round pipe 9 is a cylindrical surface, the outer port edge of the radial circular hole 9.1 on the outer peripheral surface of the round pipe is not in a plane, and the chamfering knife is inserted into the radial round hole on the outer per...

Problems solved by technology

like figure 2 As shown, since the outer peripheral surface of the round pipe 9 is a cylindrical surface, the outer port edge of the radial circular hole 9.1 on the outer peripheral surface of the round pipe is not in a plane, and the chamfering knife is inserted into the radial round hole on the outer peripheral surface of the round pipe to carry out Chamfering processing, the cutting amount of the chamfering knife on the outer port edge of the radial hole on the outer peripheral surface of the round tube is inconsistent, and the cutting amount of the chamfering knife on the high point of the outer port edge of the radial hole is the largest, while the circular The cutting amount at the low position of the outer port edge of the round hole on the outer peripheral surface of the tube is the smallest, resulting in poor chamfering uniformity of the radial round hole on the outer peripheral surface of the round tube
