[0017] The following further describes the technical solution of the present utility model in detail with reference to the preferred embodiments and their accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of them. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative work shall fall within the protection scope of the present utility model.

[0018] Please refer to Figures 1-3, the present utility model provides a technical solution: a laser cutting head cooling device, which includes an upper connector 1. The bottom of the upper connector 1 is fixedly connected to a support block 2. The bottom of the support block 2 is fixedly connected to a lower connector 3. A through hole 4 is formed on the outer wall of the lower connector 3. The top of the support block 2 is movably connected to a support shaft 5. A heat dissipation hole 9 is formed at the bottom of the support block 2. A fixed block 10 is fixedly connected to the inner wall of the support block 2. A return spring 11 is fixedly connected to the outer wall of the fixed block 10. The bottom of the support shaft 5 is fixedly connected to a fan blade 6. The bottom of the fan blade 6 is fixedly connected to a fixed shaft 7. A movable frame 8 is fixedly connected to the outer wall of the fixed shaft 7. By providing the upper connector 1, the support block 2, the lower connector 3, the through hole 4, the support shaft 5, the fan blade 6, the fixed shaft 7, the movable frame 8, the heat dissipation hole 9, the fixed block 10 and the return spring 11, it is convenient to drive the rotation of the fan blade 6 by the vibration force generated during laser cutting, so as to drive the air circulation and realize the cooling work of the cutting head, solve the problem of easy damage caused by the long-term high-temperature use of the cutting head, and there is no need for additional energy drive, effectively reducing energy consumption and achieving the effect of energy conservation and environmental protection.

[0019] Furthermore, several groups of through holes 4 are equiangularly distributed on the outer wall of the lower connector 3, and several through holes 4 in each group are equidistantly distributed, which is convenient for heat dissipation work.

[0020] Furthermore, the fan blade 6 is rotationally connected to the support block 2 through the support shaft 5, and there is a spacing between the outer side of the fan blade 6 and the inner wall of the support block 2, which is convenient for rotation work.

[0021] Furthermore, the size of the fan blade 6 is larger than the diameter of the heat dissipation hole 9, and the diameter of the heat dissipation hole 9 is smaller than the inner diameter of the lower connector 3, which further ensures the heat dissipation work.

[0022] Furthermore, the movable frame 8 is distributed in a "cross" shape, and the outer wall of the movable frame 8 abuts against one end of the return spring 11. Several return springs 11 are equiangularly distributed, which is convenient for driving the movable frame 8 to reset and rotate through the return spring 11.

[0023] During use, first install the upper connector 1 on the main shaft of the cutting machine. Then, install the cutting tool into the lower connector 3. Next, the vibration force generated by cutting will drive the fan blade 6 to rotate, causing the fan blade 6 to drive the air to flow into the lower connector 3 to cool the cutting tool. At the same time, when the fan blade 6 rotates, it drives the movable frame 8 to rotate through the fixed shaft 7, causing the movable frame 8 to drive the return spring 11 to compress and deform. As the return spring 11 is gradually compressed, the potential energy generated by the return spring 11 gradually increases. Thus, when the power generated by the vibration is less than the potential energy of the return spring 11, the elastic force of the return spring 11 will drive the movable frame 8 to rotate back to its original position, causing the movable frame 8 to drive the fan blade 6 to rotate back to its original position through the fixed shaft 7. This realizes driving the air flow to exhaust and intake respectively through the through holes 4, further improving the cooling efficiency and solving the problem that the cutting head is easily damaged due to long-term high-temperature tests.
