Abstract

The invention relates to a machining method of a stepped hole coaxiality gauge, and belongs to the technical field of slender shaft machining. The method comprises the following steps: a, selecting T10 as a gauge material, annealing the gauge material, and performing rough machining; b, quenching the gauge subjected to rough machining; c, straightening the quenched gauge, and performing finish machining after internal stress is eliminated through artificial aging; wherein the quenching in the step b is discontinuous high-frequency quenching, the current frequency is 250-350 KHz, the reference part and the detection part are divided into a plurality of sections along the length direction of the gauge, the plurality of sections comprise high-frequency quenching sections and discontinuous sections which are arranged at intervals, the high-frequency quenching sections are subjected to high-frequency quenching, and the discontinuous sections are not subjected to quenching treatment. By adopting intermittent high-frequency quenching, on the premise of ensuring the hardness and wear resistance of the reference part and the detection part in the coaxial gauge for the slender stepped hole, quenching cracks and heat treatment deformation of the coaxial gauge for the slender stepped hole caused by quenching are avoided.

Description

technical field [0001] The invention belongs to the technical field of processing slender shafts, and relates to a processing method of a step hole coaxial gauge. Background technique [0002] The coaxial gauges of conventional step holes generally have a larger diameter and a smaller depth, and the detection part and the reference part are shorter. Usually, the middle part of the gauge is set aside in the form of an empty groove, and the heat treatment method is selected as the overall carburizing and quenching method. to increase durability. [0003] However, for slender stepped holes, especially blind holes with high inner hole precision requirements, there are relatively few detection methods, and the measuring tools processed by the conventional coaxial gauge design method have both ends as the detection and positioning reference, which is difficult Reflecting the actual situation of the part, a long part in the middle of the slender hole has not been tested. The coaxi...
