Laser quenching equipment and use method

Abstract

The invention discloses laser quenching equipment and a use method. The equipment comprises a programmable logic controller, a laser, a laser head, a motion mechanism for driving a workpiece to move and a cooling liquid tank. The motion mechanism is provided with a base and a guide rod, a fixed plate is arranged on the guide rod, a motor II and a lead screw are arranged on the fixed plate, and the motor II drives the lead screw to rotate through a belt II. A connecting plate is arranged on the guide rod, a guide hole is formed in the connecting plate, the connecting plate is arranged on the guide rod in a sleeving mode through the guide hole, a screw hole matched with the lead screw is formed in one side of the connecting plate, a motor I and a connecting assembly are arranged on the other side of the connecting plate, the workpiece is arranged at the lower end of the connecting assembly, and the motor I acts on the connecting assembly through a belt I to drive the workpiece to rotate. The motor I, the motor II and the laser are in wire connection with the programmable logic controller. According to the equipment, the stability of the quality of the workpiece is ensured after laser quenching, the advantages of being high in automation degree and improving work efficiency are achieved, no additional processing exists almost, and procedures and cost are saved.

Description

technical field [0001] The invention relates to the field of laser surface quenching of shaft parts, in particular to a laser quenching device and a use method. Background technique [0002] At present, when shaft parts are subjected to laser quenching, the hardness is often sharply reduced due to temper softening caused by multiple laps. In addition, there is a problem that the production efficiency is too low when the temperature of the part is lowered after single-pass laser quenching before starting the next pass of laser quenching. Therefore, there is an urgent need to develop laser quenching equipment that can achieve high hardness and high efficiency on the surface of the workpiece. Contents of the invention [0003] The purpose of this invention is to provide a laser quenching equipment, which is used to solve the heat softening problem of the quenching area caused by heat accumulation in the laser quenching process of shaft parts, to ensure that the surface hardn...
