[0029] 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.

[0030] Reference Figure 1-Figure 2 The utility model provides an embodiment: a cooling device for laser operation, including a machine platform 1, a protective frame 2 is fixedly connected to the top of the machine platform 1, the protective frame 2 can prevent the laser processing from splashing to the outside, a heat exchanger 3 is arranged on the top of the protective frame 2, the heat exchanger 3 is a device for heat exchange of liquid, and can continuously cool water. The heat exchanger 3 is a prior art and will not be described in detail. A condenser 4 is fixedly connected to the bottom end of the heat exchanger 3, and there is water in the condenser 4, which absorbs the heat in the air in the protective frame 2 through the water. A return pipe 5 is fixedly connected to the end of the condenser 4, and the return pipe 5 is used to cool the air. The water in the condenser tube 4 can circulate into the heat exchanger 3. The side wall of the protective frame 2 is provided with a heat dissipation mechanism. The top of the protective frame 2 is fixedly connected with an air outlet 7. Part of the heat will be discharged from the air outlet 7 to improve the heat dissipation effect of the entire laser processing. The outer wall of the protective frame 2 is slidably connected with a shielding door 8. The shielding door 8 is made of transparent material, which allows the staff to observe the laser processing from the outside. The outer wall of the machine 1 is fixedly connected with a support base 9. The bottom end of the support base 9 is fixedly connected with a movable tube 10. The bottom end of the movable tube 10 is provided with a laser 15. The laser 15 is a prior art and is mainly used in the field of laser processing, which will not be described in detail here.

[0031] Reference Figure 2-Figure 4The bottom end of the movable tube 10 is rotatably connected with a circular ring 11, and the outer wall of the circular ring 11 is elastically connected to the limit block 13 through a return spring 12. The bottom end of the circular ring 11 is fixedly connected with a connecting seat 14. The connecting seat 14 mainly connects the two groups of lasers 15 and can be connected to the laser 15 through an external device, so that the laser 15 can generate a light beam for processing. The outer wall of the circular ring 11 is fixedly connected to one end of the return spring 12. When the limit block 13 moves to the right, the return spring 12 will be stretched. When resetting, the return spring 12 is used to stretch. When resetting, the elastic force of the return spring 12 is used to reset the limit block 13. The other end of the return spring 12 is fixedly connected to the inner side wall of the limit block 13. The limit block 13 penetrates and is slidably connected to the inner wall of the circular ring 11. The limit block 13 is plugged into the outer wall of the movable tube 10. A notch is provided on the movable tube 10, and the notch is symmetrically arranged, so that the connecting seat 14 can be rotated 180 degrees to allow the limit block 13 to be plugged into its notch.

[0032] Reference Figure 1-Figure 3 The laser 15 is arranged at the bottom end of the connecting seat 14, and the heat dissipation mechanism includes a fan 6, which is arranged on the side wall of the protective frame 2. The fan 6 can blow out most of the heat in the protective frame 2 to reduce the temperature in the protective frame 2, and the fan 6 is connected through an external device. The return pipe 5 passes through and is fixedly connected to the inner wall of the protective frame 2, and the condenser 4 passes through and is fixedly connected to the inner wall of the protective frame 2.

[0033] Working principle: First, when processing is required, just move the shielding door 8 to open the opening of the protective frame 2, place the workpiece in the protective frame 2, and then close the shielding door 8 to prevent sparks from splashing. Then, use an external device to operate the laser 15 for subsequent processing. At the same time, start the heat exchanger 3 to allow water to enter the condenser 4. The water in the condenser 4 absorbs heat from the air. Finally, let the water flow back to the heat exchanger 3 through the reflux pipe 5 for cooling. While absorbing heat, start the fan 6 to blow out part of the heat in the air from the air outlet 7 through wind power, which can reduce the temperature in the protective frame 2 and allow the laser 15 and the workpiece to be cooled.

[0034] When a group of lasers 15 needs to be cooled down after long-term use, it is only necessary to pull the limit block 13 outward to separate the limit block 13 from the outer wall groove of the movable tube 10, and the other group of lasers 15 can be processed corresponding to the workpiece by rotating the connecting seat 14 one hundred and eighty degrees. When limiting, it is only necessary to loosen the limit block 13 and use the reverse elastic force of the reset spring 12 to reset the limit block 13, so that the limit block 13 is plugged into the outer wall groove of the movable tube 10, and the entire connecting seat 14 and the laser 15 can be limited. When processing for a long time, the connecting seat 14 and the laser 15 can be rotated according to the above steps, so that the two groups of lasers 15 can be used for processing in a cycle, so that one group can be cooled down.

[0035] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
