Problems solved by technology

[0002] When shaft parts are subjected to laser quenching, the hardness is often sharply reduced due to temper softening caused by multiple laps
In addition, waiting for the temperature of the part to drop after single-pass laser quenching before starting the next pass of laser quenching will lead to low production efficiency

Abstract

The invention discloses a quick quenching device and method for shaft parts. The quick quenching device for shaft parts is provided with a temperature monitoring device, a laser device, a liquid nitrogen cooling system, a workpiece clamp and a connecting plate assembly, wherein the connecting plate assembly is provided with a manipulator connecting plate, a connecting component and a spray nozzle connecting plate, a laser head is installed on the manipulator connecting plate, and a liquid nitrogen spray nozzle is installed on the spray nozzle connecting plate and is connected with a liquid nitrogen cooling system control valve through an air delivery pipe. The workpiece clamp is arranged under the connecting plate assembly and is provided with a chuck, a tip and a control system for controlling rotation of the chuck, and a workpiece is arranged between the chuck and the tip. The temperature monitoring device is arranged on one side of the connecting plate assembly and is used for monitoring the temperature of a laser quenching zone on the workpiece. By the adoption of the quick quenching device and method for shaft parts, the automation degree of surface laser strengthening of large shafts can be improved, working efficiency can be improved, shaft surface strengthening and near-net shaping can be also achieved, additional machining is not needed basically, and working procedures and cost are saved.

Description

technical field [0001] The invention relates to the field of quenching of shaft parts, in particular to a rapid quenching device and method for shaft parts. Background technique [0002] When shaft parts are subjected to laser quenching, the hardness is often sharply reduced due to temper softening caused by multiple laps. In addition, waiting for the temperature of the part to drop after single-pass laser quenching before starting the next pass of laser quenching will lead to too low production efficiency. Therefore, it is an urgent technical problem to be solved by those skilled in the art to develop a new device capable of high-speed and large-area laser quenching. Contents of the invention [0003] The invention aims at the deficiencies of the prior art, and provides a fast quenching device for shaft parts, which has a temperature monitoring device, a laser, a liquid nitrogen cooling system, a workpiece fixture and a connecting plate assembly; the connecting plate ass...
