[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] The utility model provides Figure 1-6 A multi-station precision machining mechanism shown in the figure comprises a machining table 1 and a machining chamber 2 on the machining table 1, a feeding transmission shaft 7 is arranged in the machining chamber 2, a feeding table 8 is connected to the feeding transmission shaft 7, a laser emitter 4 is arranged above one side of the feeding table 8 and in the machining chamber 2, and an equipment box 9 is arranged at the lower end of the machining table 1.

[0027] The laser heat dissipation device 10 is located on the equipment box 9. A mounting frame 11 is provided on the laser heat dissipation device 10. A shell 12 is provided inside the mounting frame 11. A connecting frame 16 is provided at the front end of the shell 12 and located on the mounting frame 11. A liquid-cooled heat dissipation radiator 19 is provided inside the shell 12. A driving shaft 20 is provided at the front end of the liquid-cooled heat dissipation radiator 19. An embedding groove 24 is provided on one end of the driving shaft 20. A fan 15 is provided in the embedding groove 24, and the fan 15 is connected to the embedding groove 24 by embedding.

[0028] In the utility model, the workpiece moves in the processing chamber 2 through the loading table 8 on the loading transmission shaft 7. First, the camera 6 located above the loading table 8 captures the position and posture of the workpiece, and sends the information to the program processing center in the equipment box 9. Then, the industrial control computer program makes corresponding adjustments to the emission angle of the laser laser emitter 4 according to the received workpiece position and posture information, so that when the workpiece passes through the laser laser emitter 4, the laser irradiation angle of the laser laser emitter 4 is aligned with the surface to be lasered of the workpiece. When the workpiece moves to the bottom of the laser laser emitter 4 with the loading table 8, the laser beam generated by the laser laser emitter 4 accurately hits the surface to be lasered of the workpiece and lasers the corresponding texture. The workpiece after lasering continues to move with the loading table 8 to the outside of the processing chamber 2 and enters the unloading table 6 to be collected. When the laser laser emitter 4 is working, it needs to generate and emit a high-energy laser beam, and the laser laser emitter 4 and related equipment will emit a large amount of heat. The heat generated by the laser emitter 4 is timely dissipated through the laser heat dissipation device 10. The heat generated by the laser emitter 4 is connected through the liquid-cooled heat dissipation radiator 19 connected to the base. The liquid medium circulating in the liquid-cooled heat dissipation radiator 19 absorbs a large amount of heat when flowing through the heat dissipation copper plate connected to the base of the laser emitter 4. The temperature of the liquid medium here rises and flows to the other end of the liquid-cooled heat dissipation radiator 19, which is the end connected to the fan 15. The cylindrical liquid-cooled heat dissipation radiator 19 can increase the area of ​​heat exchange between the internal liquid medium and the external environment. In addition, the fan 15 driven by the motor in the connecting frame 16 can further accelerate the heat dissipation of the liquid medium whose temperature rises due to absorbing the heat of the laser emitter 4 by increasing the air flow rate on the outer surface of the liquid-cooled heat dissipation radiator 19, thereby avoiding overheating of the laser emitter 4, ensuring the normal and stable operation of the processing mechanism, and preventing the laser emitter 4 that emits a high-energy laser beam from causing abnormal processing accuracy due to excessive temperature.

When dust accumulates on the blades of the fan 15 and needs to be cleaned, the fan 15 body can be directly removed from the drive shaft 20 for cleaning, thereby improving the cleaning effect.

[0033] In an optional embodiment, a fixed cover 25 is provided on the inner side of the grid 14 and on one end of the drive shaft 20. The fixed cover 25 is connected to one end of the drive shaft 20 by a rotational connection, and a built-in motor structure is provided between the other end of the drive shaft 20 and the liquid-cooled radiator 19.

[0034] In this embodiment, when the air flow rate flowing through the outer surface of the liquid-cooled radiator 19 is increased by the fan 15, the cylindrical structure of the liquid-cooled radiator 19 can increase the surface area to improve the efficiency of heat exchange between the liquid-cooling medium inside the liquid-cooled radiator 19 and the external environment.

[0035] In an optional embodiment, one end of the shock-absorbing pad 21 is fixedly connected to the connecting frame 16 via an adjusting bolt passing through the connecting hole 17 .

[0036] In an optional embodiment, a mounting groove 18 is provided in the middle of the shell 12 , and the size of the mounting groove 18 is consistent with the size of the liquid cooling radiator 19 .
