Non-eccentricity type through hole double-face chamfering tool and chamfering process using chamfering tool

Abstract

The invention relates to a non-eccentricity type through hole double-face chamfering tool. The non-eccentricity type through hole double-face chamfering tool comprises a clamping part and a machiningpart which are integrally molded, and the central axis of the clamping part and the central axis of the machining part are located on one straight line; and the machining part comprises an upper chamfering part, a lower chamfering part and a chamfering anti-interference part located between the upper chamfering part and the lower chamfering part, and the central axes of the chamfering anti-interference part, the upper chamfering part and the lower chamfering part are located on one straight line. The tool is simple in structure, convenient to use and complete in function; in cooperation with acorresponding chamfering process, the number of tool walking steps is reduced, the process is simplified, and the production period is shortened; and on the basis of guaranteeing the accuracy and stability, the machining efficiency is improved, the structure strength is good, manpower and material resources are saved, production is safe and reliable, and the non-eccentricity type through hole double-face chamfering tool is worthy of application and popularization.

Description

technical field [0001] The invention relates to the technical field of through-hole chamfering, in particular to a non-eccentric through-hole double-sided chamfering tool and a chamfering process using the chamfering tool. Background technique [0002] Since there are multiple threaded holes or bolt holes on the flange surface of the automobile wheel bearing, in the production process of the automobile wheel bearing, in the drilling process, it is necessary to process multiple through holes (bolt holes) on the flange surface of the automobile wheel bearing. hole or threaded bottom hole), because the front and back of the through hole are correspondingly provided with chamfering, the existing chamfering process of the through hole on the flange surface of the automobile hub bearing includes: 1. Use the chamfering drill to chamfer the chamfer The processing technology and the chamfering processing technology using the eccentric chamfering knife for chamfering, and the processi...
