Description

Technical Field

[0001] The invention relates to the technical field of machining, and in particular to a turntable type jet device and a working method for a water-guided laser machining system. Background Art

[0002] Water-guided laser technology is one of the most cutting-edge high-efficiency precision processing technologies in the world. Its principle is to make a laser beam enter a "hair-thin" water jet after a set of extremely precise light-water coupling treatment and conduct total reflection. Usually, the diameter of this water jet is at the level of tens of microns, so the processing accuracy of this technology is also very high, even 50 to 100 times that of conventional laser cutting. Therefore, this technology can be widely used in high-end manufacturing industries such as aerospace equipment, medical equipment, and semiconductor micro-processing.

[0003] When water-guided laser processes workpieces of different materials / thicknesses, the corresponding nozzles need to be replaced to change the jet parameters, and the jet nozzles are also consumable parts and usually need to be replaced regularly. However, since water-guided laser processing has extremely stringent technical requirements for water jet nozzles, it not only needs to have extremely high hardness and rigidity to resist high-pressure water jet erosion, but also has to have extremely low absorption rate of the processing light beam, and requires micron-level high-precision processing to ensure stable output of the water jet. Therefore, water jet nozzles are usually made of precious materials such as diamonds and are manufactured through ultra-fine precision processing technology, so the cost is extremely high. In addition, since water-guided laser processing also has extremely high requirements for light-water coupling accuracy, the operation of replacing water jet nozzles is also very cumbersome and time-consuming, which brings a lot of inconvenience to actual production.

[0038] See also Figures 1 to 4 As shown, the present invention provides a turntable jet device for a water-guided laser processing system, comprising: a shell 1, wherein a light-water coupling cavity 2 is provided in the shell 1, and a water inlet hole 3 is provided on the side wall of the shell 1, wherein the water inlet hole 3 is used to circulate the water jet, and a through hole 4 is provided at the bottom of the light-water coupling cavity 2; a laser incident window 5, which is provided at the upper end of the shell 1; a rotating mechanism 6, which is partially provided in the shell 1, and a turntable nozzle 7 is installed on the rotating mechanism 6, wherein the through hole 4 is tightly combined with the surface of the turntable nozzle 7, and a plurality of jet nozzles 8 are provided on the turntable nozzle 7, wherein the processing laser beam enters the light-water coupling cavity 2 through the laser incident window 5, passes through the through hole 4, is coupled with the water jet at the upper opening of the jet nozzle 8, and then enters the surface of the processing specimen along the water jet channel; a position adjustment mechanism 9, which is provided at the bottom of the shell 1, and the position adjustment mechanism 9 is used to adjust the position of the rotating mechanism 6.

[0039] By adopting a turntable design to process a plurality of jet nozzles 8 on a disc-shaped water jet nozzle, the jet nozzles 8 on the turntable nozzle 7 can be quickly replaced by rotating the turntable nozzle 7 or changing the position of the turntable nozzle 7, which can effectively improve the utilization efficiency of the water jet nozzle and greatly reduce the manufacturing cost of the jet nozzle; the through hole 4 is tightly combined with the surface of the turntable nozzle 7, and the through hole 4 can only contain one jet nozzle 8 at the same time. This arrangement ensures that the turntable jet device used in the water-guided laser processing system will not leak, and the rotating mechanism 6 is used to drive the turntable nozzle 7 to rotate along the center, so that all the jet nozzles 8 on the circumference of a specific distance can be quickly moved to the coaxial position of the processing beam, which effectively solves the installation accuracy problem when the turntable jet nozzle 7 is repeatedly replaced, and makes the operation simpler, and the replacement efficiency is greatly improved; and the rotating mechanism 6 is convenient for manually adjusting the rotation angle of the rotating mechanism 6 to achieve the replacement of the nozzle.

[0040] At the same time, the design method that the rotating mechanism 6 can move or lock along the position adjustment mechanism 9 can realize the effective switching of the jet nozzles 8 on the circumference of multiple radius distances, thereby, the number of available jet nozzles 8 can be further increased by 2-10 times. This design can conveniently assist in adjusting the positions of different jet nozzles 8, has the advantages of simple operation, good reliability, high efficiency, etc., and has good practicality; when water-guided laser processing workpieces of different materials / thicknesses, different types of jet nozzles can be quickly replaced to change the jet parameters, and the operation is convenient and the working stability is good.

[0041] In some optional embodiments, the plurality of jet spray holes 8 are arranged at intervals along one or more circumferences of the surface of the rotating disk nozzle 7. That is, the plurality of jet spray holes 8 can be arranged on the circumference of the same radius, and the number of the jet spray holes 8 can be determined according to the size of the rotating disk nozzle 7, such as 2, 3, 4, etc. When the rotating disk nozzle 7 rotates, the jet spray holes 8 located on the circumference of the same radius can rotate around the center of the rotating mechanism 6, so as to realize the rapid conversion of different jet spray holes 8.

[0042] In some optional embodiments, the plurality of jet nozzles 8 include one or more groups, which are arranged on one or more circles on the surface of the rotating disk nozzle 7, and each group is spaced or staggered.

The number of circles at different radius distances can be determined according to the size of the turntable nozzle 7, such as 2 layers, 3 layers, 4 layers, etc. If the jet nozzles 8 are located on the circumference of the radius R1, and the jet nozzles 8 are located on the circumference of the radius R2, by adjusting the position of the center distance of the rotating mechanism from the processing laser beam, the jet nozzles 8 on the circumference at different radius distances can be adjusted to the focusing position of the processing laser beam.

[0044] The positions of the jet nozzles 8 can be evenly distributed on a circle at a certain specific distance from the center of the disc on the surface of the rotating disc nozzle 7, or can be evenly distributed on circles at multiple specific distances, such as on one or more circles at unequal distances from 1 / 4 to 3 / 4 of the outer radius of the disc.

[0050] In some optional embodiments, the rotating member 10 is provided with a plurality of jet openings 13 for releasing the water jet formed by the jet orifice 8. Through the arrangement of the jet openings 13, the processing laser beam can enter the optical-water coupling cavity 2 through the laser incident window 5, pass through the through hole 4, couple with the water jet at the upper opening of the jet orifice 8, and then enter the surface of the processing specimen along the water jet channel;

In addition, the rotating part 10 of the rotating mechanism 6 can be marked with an angle mark to indicate the angle of rotation, to assist in adjusting the position of different jet nozzles 8, so that the jet nozzles 8 on different circumferences in the turntable nozzle 7 can also be moved to the focusing position of the processing laser beam.

[0053] In some optional embodiments, the housing 1 includes a plate 16 and a body 17, the body 17 is provided with an opening, the rotating mechanism 6 partially extends out of the body 17, and a jet hole 18 is opened on the plate 16, the jet hole 18 is coaxial with the through hole 4 and does not contact the water jet.

[0055] Among them, the optical-water coupling chamber 2 is arranged in the main body 17.
