Problems solved by technology

[0006] However, this action will cause the water cooling tube to exert a downward force on the gas storage tube, which will affect the straightness of the gas storage tube, thereby affecting the parallelism requirements of the reflective mirror and the output mirror, and this effect will increase with the axial growth of the carbon dioxide laser. It is becoming more and more obvious that when the carbon dioxide laser exceeds 1.8m, it is difficult to ensure the parallelism requirements of the reflective mirror and the output mirror, which severely limits the design length of the carbon dioxide laser, thus greatly limiting the use prospect of the carbon dioxide laser

Embodiment 1

[0073] Such as figure 1 and 2 As shown, a laser device with an integral support assembly includes a laser 1 and a support 2 for supporting the laser 1. The laser 1 includes a gas storage tube 11, a water cooling tube 12 and a A discharge tube 13, the two ends of the water-cooling tube 12 are respectively connected with a liquid inlet pipe 121 and a liquid outlet pipe 122, and the end of the liquid inlet pipe 121 far away from the water-cooling pipe 12 is connected through the gas storage pipe 11, the The end of the liquid outlet pipe 122 away from the water cooling pipe 12 is connected through the gas storage pipe 11, at least one of the liquid inlet pipe 121 and the liquid outlet pipe 122 is flexibly connected to the gas storage pipe 11, and the gas storage pipe The side wall of 11 has a support portion 14 that supports and cooperates with the support 2, and a support transition device 3 for supporting the water-cooled tube 12 is provided between the water-cooled tube 12 and...

Embodiment 2

[0090] Such as figure 1 and 2 As shown, a laser device with an integral support assembly described in this application is different from Embodiment 1 in that an electrode part 131 is provided on the end of the discharge tube 13 near the helical structure, and the helical structure The structure is sleeved on the outside of the electrode part 131 .

[0091] In the prior art, there is still no good heat dissipation auxiliary parts around the electrode part 131, which causes the electrode part 131 to generate heat frequently, which affects the deformation of the electrode part 131, thereby reducing the output accuracy of the laser;

[0092] The helical structure of this solution is set on the outside of the electrode part 131, so that the coolant passing through the helical structure can take away most of the heat emitted by the electrode part 131, preventing the electrode part 131 from affecting the laser 1 due to excessive temperature. The output accuracy, thus ensuring the o...

Embodiment 3

[0096] Such as figure 1 As shown, a laser device with an integral support assembly described in this application is different from Embodiment 1 or 2 in that when only one layer of support transition is needed to solve the problem to be solved in this application, the support The transition device 3 includes a support pipe 31 and a support member 33, the support pipe 31 is sleeved outside the water-cooled pipe 12, and the support member 33 is arranged between the water-cooled pipe 12 and the support pipe 31 for To support the water-cooled tube 12, the legs 15 are connected between the support tube 31 and the support portion 14, the support tube 31 is a hollow structure with both ends open, and the bending rigidity of the support tube 31 is greater than The bending rigidity of the water-cooled tube 12 .

[0097] The bending stiffness of the support tube 31 is greater than that of the water-cooled tube 12, so that the number of legs 15 can be effectively reduced through the tran...

Abstract

The invention relates to the technical field of lasers and particularly relates to a laser apparatus having an integral supporting assembly, which comprises a laser and a support for supporting the laser. At least one of a liquid inlet tube and a liquid outlet tube is flexibly connected with a gas storage tube; the side wall of the gas storage tube is provided with a supporting part matched with the support in a supporting mode; a supporting transition device used for supporting a water-cooled tube is arranged between the water-cooled tube and the gas storage tube; the bending rigidity of thesupporting transition device is larger than that of the water-cooled tube; the supporting transition device is connected with the gas storage tube through at least two supporting legs in a supportingmode; and all the supporting legs are distributed on at least two supporting parts. According to the laser apparatus having the integral support assembly, the straightness of a discharge tube and thecooling effect of the water-cooled tube are ensured, and meanwhile, the influences of the discharge tube and the water-cooled tube on the gas storage tube can be greatly reduced, so that the straightness requirement of the gas storage tube is ensured, and the parallelism requirement of a reflecting lens and an output lens is further ensured.

Description

technical field [0001] The invention relates to the technical field of lasers, in particular to a laser device with an integral support assembly.
