Novel carburizing and quenching protection structure for gear shaft machining

The utility model relates to the field of carburizing and quenching processes, in particular to a novel carburizing and quenching protection structure for gear shaft machining, which comprises a frontend clamping mechanism and a rear end clamping mechanism which are used for radially clamping one end part of a gear shaft workpiece to be carburized and quenched. Wherein the front end clamping mechanism and the rear end clamping mechanism are vertically arranged, the rear end clamping mechanism is located on the side portion of the front end clamping mechanism, and the front end clamping mechanism and the rear end clamping mechanism can be adjusted according to the outer diameter of a gear shaft workpiece. Quenching oil is prevented from entering the end and the bearing shaft body which donot need to be quenched as much as possible, and the machining cost and the machining time of the gear shaft workpiece are reduced. 本实用新型涉及渗碳淬火工艺领域，具体是涉及一种新型齿轮轴类加工用渗碳淬火保护结构，包括前端夹持机构和后端夹持机构，所述前端夹持机构和所述后端夹持机构用于对待渗碳淬火的齿轮轴工件一端端部进行
