Description

Technical Field

[0001] The utility model relates to the technical field of laser quenching equipment, in particular to a spectroscopic laser quenching head. Background Art

[0002] Laser quenching is a surface treatment technology that irradiates the workpiece surface with a high-energy-density laser beam, causing it to reach a high temperature in a short period of time and then cool rapidly, thereby changing the physical and chemical properties of the workpiece surface and improving wear resistance, corrosion resistance, and hardness.

[0003] During the laser quenching process, the energy distribution and spot shape of the laser beam have an important influence on the quenching effect. Traditional laser quenching heads have limitations in adjusting the energy distribution and spot shape of the laser beam, resulting in unstable quenching effects and difficulty in adapting to workpieces of different shapes and sizes. It is necessary to develop a spectroscopic laser quenching head to improve practicality.

[0004] Chinese Patent Publication No.: CN220432888U discloses "A Spectral Laser Quenching Head". The interior of the shell is formed into a channel, and a collimator is arranged at one end of the channel facing the incident direction of the laser beam. The direction of the laser beam passing through the integrator mirror is changed, and it is emitted to the bottom of the channel in a direction perpendicular to the original laser beam. The laser beam whose direction is changed by the integrator mirror can be emitted into the spectroscope to divide the laser beam into two sub-laser beams at a certain angle. The two sub-laser beams can be emitted to the reflector respectively and reflected by the reflector to the corresponding light outlet and to the surface of the workpiece. The spectroscopic laser quenching head has a simple structure and can quench two adjacent surfaces of the workpiece at the same time by two laser beams, avoiding the problem that the laser beam scans the quenched area for the second time to form a tempered structure, resulting in a reduction in the hardness of the sharp corners and the middle of the raceway, thereby ensuring that the surface of the workpiece and the sharp corners and the middle of the raceway can have a higher quenching hardness.

[0005] The above-mentioned prior art uses two laser beams to quench two adjacent surfaces of a workpiece at the same time, thereby avoiding the laser beam from scanning the quenched area for a second time to form a tempered structure. However, the existing equipment does not have the function of adjusting the laser beam energy distribution and spot shape during use. When in use, it can only provide one laser beam energy distribution and spot shape, and cannot be adjusted according to the different laser quenching workpieces required, which has certain limitations. Utility Model Content

[0011] Preferably, the mounting blocks are in two groups, and the two groups of mounting blocks are symmetrically arranged at the lower end of the laser quenching output head, and the cross bar passes through the placement slot and extends to the outside of the mounting blocks.

The installation bin is placed in the symmetrically arranged installation blocks, and the moving block is released. The compressed spring resets and drives the limit block to move, thereby driving the pin to be stuck in the slot opened in the installation bin at the position corresponding to the pin.
