A chamfering method for radial circular holes on the outer peripheral surface of circular tubes

Abstract

The invention discloses a chamfering method for a radial round hole in the peripheral face of a round pipe. According to the chamfering method provided by the invention, machining is convenient, chamfering uniformity of the radial round hole in the peripheral face of the round pipe can be ensured effectively. The chamfering method for the radial round hole in the peripheral face of the round pipe sequentially comprises the following steps that 1, the round pipe is inserted in a horizontal installation shaft sleeve, the horizontal installation shaft sleeve is rotated, and thus the radial round hole in the peripheral face of the round pipe is downward; 2, a shaft sleeve drive motor drives the round pipe to rotate by 180 degrees, and thus the radial round hole in the peripheral face of the round pipe is upward; 3, a chamfering knife drive motor drives a vertical chamfering knife to rotate, and meanwhile, a lifting performing mechanism drives the vertical chamfering knife to move down in place; and 4, the shaft sleeve drive motor drives the round pipe to rotate clockwise by the set angel beta, then the shaft sleeve drive motor stops working, then the shaft sleeve drive motor drives the round pipe to rotate anticlockwise by the set angle of 2beta, and then the shaft sleeve drive 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. 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 periph...

AI Technical Summary

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
