The specific meaning of such terms in this patent will be understood by those of ordinary skill in the art as the case may be.
As shown in fig. 1-2, the water cooling mechanism for a cutting head provided in this embodiment includes:
the cutting head connecting plate 1 with the through hole is sleeved outside the laser cutting head 7, and the cutting head connecting plate 1 and the main body 8 are sealed, attached and fixed towards the end face of one side of the laser cutting head 7;
the hollow water cooling ring 3 is sleeved outside the laser cutting head 7, the end face of one side of the water cooling ring 3 facing the main body 8 is in sealing fit with the end face of one side of the cutting head connecting plate 1 facing away from the main body 8, and two water pipe connectors 4 are fixedly arranged on the side wall of the water cooling ring 3;
the lower cover plate 6 with the through holes is sleeved outside the laser cutting head 7, the end face of one side of the lower cover plate 6 facing the main body 8 is in sealing fit with the end face of one side of the water cooling ring 3 facing away from the main body 8, and the through hole opening of one side of the lower cover plate 6 facing away from the main body 8 is in sealing butt joint with the outside of the laser cutting head 7.
In this embodiment, cutting head connecting plate 1 with main part 8 bottom sealing connection, water-cooling ring 3 with cutting head connecting plate 1 sealing connection, lower apron 6 with water-cooling ring 3 sealing connection, lower apron 6 through-hole opening with laser cutting head 7 lateral surface sealing connection, based on above-mentioned structure, main part 8 cutting head connecting plate 1 water-cooling ring 3 lower apron 6 laser cutting head 7 constitutes a sealing system jointly, the sealing system will laser cutting head 7 need refrigerated part parcel is including, just water pipe joint 4 with sealing system intercommunication.
The two water pipe connectors 4 are respectively communicated with the cooling water inlet pipe and the water return pipe, then the water inlet pipe is opened, so that cooling water smoothly enters the sealing system, and after the sealing system is filled with the cooling water, the cooling water can flow out along the water return pipe and continuously cool the laser cutting head 7. The circulating cooling water continuously takes away the heat radiated by the steel plate from the cutting head nozzle and the ceramic body, so that overheat alarm of the cutting head temperature sensor is avoided.
Therefore, the water cooling mechanism provided by the embodiment is equivalent to directly immersing the cutting head in cooling water, has no intermediate heat transfer process, and has good cooling effect and high cooling efficiency.
An upper sealing ring 2 is arranged between the water cooling ring 3 and the cutting head connecting plate 1, and the upper sealing ring 2 is sleeved outside the laser cutting head 7.
