Embodiment

[0024] Example: such as figure 2 As shown, a heat treatment equipment for an automobile engine rocker shaft includes: a workpiece feeding device, a high-frequency heating induction coil 2 for high-frequency heating of a workpiece 1 to be processed, and a positioning mechanism for clamping and positioning the workpiece 1 to be processed.

[0025] The positioning mechanism includes an upper positioning shaft 10 arranged directly above the high-frequency heating induction coil 2 for clamping the workpiece 1 to be processed, and a lower shaft 10 arranged directly below the high-frequency heating induction coil 2 for clamping the workpiece 1 to be processed. Position axis 20. The upper positioning shaft 10 and the lower positioning shaft 20 clamp and limit the workpiece 1 to be processed in the center of the high-frequency heating induction coil 2 by two upper and lower positions.

[0026] The upper positioning shaft 10 is provided with an upper rotating motor 11 which can make t...

Abstract

The invention discloses a heat treating equipment for a rocker arm shaft of an automobile engine, which comprises a high-frequency heating induction coil (2) for performing high-frequency heating on a to-be-processed workpiece (1), wherein the upside and the downside of the high-frequency heating induction coil (2) are correspondingly provided with a positioning mechanism which clamps and limits the upper part and the lower part of the to-be-processed workpiece (1) in the center of the high-frequency heating induction coil (2); and the positioning mechanism comprises an upper positioning shaft (10) and a lower positioning shaft (20) which are arranged right above and under the high-frequency heating induction coil (2) and are used for clamping the to-be-processed workpiece (1). The upper positioning shaft (10) is provided with an upper rotating electrical machine (11) and a cylinder (12) capable of making the upper positioning shaft (10) move up and down; and the lower positioning shaft (20) is provided with a lower rotating electrical machine (21) and a swing mechanism capable of making the lower positioning shaft (20) swing up and down. The heat treating equipment meets special heat treating requirements of a part, and has the advantages of stable product quality, high automation degree and high production efficiency.

Description

technical field [0001] The invention relates to a heat treatment device, in particular to a special heat treatment device for a rocker shaft of an automobile engine. Background technique [0002] The requirements for the heat treatment of the rocker arm shaft of the automobile engine are relatively special, refer to figure 1 As shown, near the two ends of the shaft (point C) is the quenched and tempered hardness of the raw material: HV200~336, the middle part in contact with the needle bearing: the surface hardness of point A requires HV653~832, and the depth of the hardened layer is within 0.5mm from the surface of HV ≥500, the surface hardness of point B requires HV697~832, and the hardened layer depth is within 1mm from the surface, HV≥500; and the axial dimension of the parts with low hardness at both ends is very short. [0003] Due to the special heat treatment requirements of this kind of parts, the heat treatment process is relatively difficult. Therefore, there is ...
