Double-sided chamfering tool

Abstract

The invention discloses a double-sided chamfering cutter, and relates to the technical field of mechanical milling machining cutters, the double-sided chamfering cutter comprises a cutter bar, a cutter hole is formed in the side wall of the cutter bar, an elastic piece is fixed in the cutter hole, a chamfering cutter is fixed on the elastic piece, the chamfering cutter has at least two cutting edges, and the directions of the at least two cutting edges are opposite; the moving direction of the elastic piece is perpendicular to the rotating shaft of the cutter bar. The direction of at least one cutting edge of the chamfering cutter is opposite to that of a cutting edge of a common cutter for numerical control milling, and the cutting edge can chamfer the back face of a workpiece. When the cutter bar does not rotate, the chamfering cutter retracts into the cutter hole, so that other parts of the workpiece cannot be damaged by the chamfering cutter in the moving process of the cutter bar, and when the cutter bar moves to a to-be-chamfered position on the back surface of the workpiece, the cutter bar rotates to generate centrifugal force, so that the elastic piece drives the chamfering cutter to extend out of the cutter hole and protrude out of the cutter bar; and chamfering the corresponding position of the back surface of the workpiece.

Description

technical field [0001] The invention relates to the technical field of mechanical milling tools, in particular to a double-sided chamfering tool. Background technique [0002] In milling, chamfering is one of the more common processing techniques. The existing chamfering methods mainly include two types: the first method is manual chamfering, that is, the fitter uses a drill to perform chamfering, the chamfering effect is poor and the efficiency is low, and it is suitable for occasions with low requirements; the second method is through chamfering The corner knife is combined with programming for chamfering, which has relatively high accuracy and efficiency. [0003] However, both methods require secondary chamfering, that is, after the operator completes one side, he needs to turn the workpiece over and perform chamfering again, which is unfavorable for the consistency of chamfering; The position of the clamp is offset from the position of the last clamping, which needs t...

[0003] However, both methods require secondary chamfering, that is, after the operator completes one side, he needs to turn the workpiece over and perform chamfering again, which is unfavorable for the consistency of chamfering; The position of the clamp is offset from the position of the last clamping, which needs to be programmed again, which will undoubtedly cause low chamfering efficiency
