Abstract

The invention relates to a local centering and rotating device of a cone socket, which can keep a clearance between a high-frequency induction coil and the cone socket surface according to the requirements of a quenching process stable, thereby solving the problems of effective hardening depth and stable hardness difference. The local centering and rotating device is characterized by comprising arotating disc and a driving motor, wherein the rotating disc is arranged on a rotating shaft which is arranged on a bracket through a bearing, the bracket is arranged on a bottom plate, the rotating shaft is connected with the driving motor by a driving mechanism, and an eccentric positioning disc is arranged on the surface of the rotating disc.

Description

(1) Technical field [0001] The invention relates to the field of local quenching tooling on the surface of castings, in particular to a cone socket local centering rotating device. (2) Background technology [0002] 55 horsepower tractor brake pressure plate, its material is ductile iron casting QT450-10, its structure is circular, with six 144° conical dimples evenly distributed on the circular surface, the six conical dimples are partially quenched, and the inner surface quenching hardness is HRC35 in the area of ​​φ18 ~50, the effective hardening depth is 1.5~3.0, the validity period of the quenching hardness on the surface of a single cone dimple is not greater than HRC5, and the ordinary local quenching process is adopted, the quenching surface is easily deformed, destroying the original processing accuracy, and the effective hardening depth and hardness difference cannot be guaranteed. requirements. (3) Contents of the invention [0003] The invention provides a con...
