Abstract

The invention provides quenching treatment equipment and a quenching treatment process for an engine crankshaft. The equipment comprises a mounting bottom plate, supporting frames, cooling mechanismsand clamping rotating mechanisms, the supporting frames are symmetrically mounted at the upper end of the mounting bottom plate, the cooling mechanisms are symmetrically mounted on the supporting frames in a sliding fit mode, the clamping rotating mechanisms are symmetrically mounted on the cooling mechanisms in a rotating fit mode, and the clamping rotating mechanisms are located between the supporting frames. The relative position of the crankshaft in the cooling process is adjusted in real time through a shifting motor and a lifting motor; the working intensity of workers is reduced; the clamping rotating mechanisms are capable of stably clamping the engine crankshaft in a complex shape; the crankshaft is continuously rotated in the cooling process to enable the complex surface of the crankshaft to be stably, evenly and rapidly cooled; and the working efficiency of cooling work is improved.

Description

technical field [0001] The invention relates to the technical field of engine crankshaft quenching treatment, in particular to engine crankshaft quenching treatment equipment and a quenching treatment process. Background technique [0002] The engine crankshaft is generally made of special 42CrMoA steel. After being forged and formed and kept warm for a period of time, it needs to be taken out of the furnace and cooled by cooling liquid or sprayed with water, sprayed or blown for metal heat treatment. [0003] Due to the complex shape of the engine crankshaft and the large cross-sectional size of the sampling part, it is difficult to perform uniform cooling during the coolant cooling process, and the requirements for the comprehensive mechanical properties of the cooling device are relatively high. However, the engine crankshaft quenching treatment in the current market has the following problems during operation Problem: a. During the cooling process of the engine crankshaf...
