Description

Technical Field

[0001] The invention relates to the technical field of lasers, in particular to a carbon dioxide laser with an adjustable supporting device. Background Art

[0002] Because carbon dioxide lasers have relatively large power and relatively high energy conversion efficiency, their spectral lines are relatively rich, with dozens of spectral lines of laser output near 10 microns. They have been widely used in industry, military, medical treatment, scientific research and other fields.

[0003] The current carbon dioxide laser usually includes a discharge tube, a water cooling tube mounted on the outside of the discharge tube, a gas storage tube mounted on the outside of the water cooling tube, electrodes mounted on both ends of the discharge tube, and output windows and reflection windows mounted on both ends of the gas storage tube. The reflection window includes a reflection lens and a reflection lens cooling device, and the output window includes an output lens and an output lens cooling device. The discharge tube is filled with carbon dioxide gas and other auxiliary gases; the water cooling tube mounted on the outside of the discharge tube contains coolant to cool the discharge tube; when the water cooling tube and the gas storage tube cannot be supported by the water inlet and outlet pipes, a pipe is generally used. The first and second legs are fixedly connected to support the water-cooling tube. When a high voltage is applied to the electrode, a glow discharge is generated in the discharge tube, which is reflected by the reflective lens and the output lens to form a laser beam, which is emitted from the output lens to obtain the final laser beam. Therefore, when the carbon dioxide laser is in use, the parallelism of the reflective lens and the output lens on it is required to be very high, so that the gas storage tube, water-cooling tube and legs will not be greatly deformed due to temperature changes during operation, which will affect the laser output effect. Therefore, the gas storage tube, water-cooling tube and legs on the existing carbon dioxide laser are all made of brittle materials (usually glass).

[0004] However, during processing and use, when the temperature near the connection between the gas storage tube and one of the legs changes rapidly, the side wall of this part of the gas storage tube will deform, causing the distance between the connection position of the first leg and the gas storage tube and the connection position of the second leg and the gas storage tube to change. However, since the temperature on one side of the water-cooling tube does not change much, the distance between the connection position of the first leg and the water-cooling tube and the connection position of the second leg and the water-cooling tube does not change, or changes very little. Since the distance between the two legs cannot be adjusted, this will often cause the connection position of one of the legs to the gas storage tube or the water-cooling tube to break, causing the entire carbon dioxide laser to be damaged, reducing the yield of the carbon dioxide laser, and at the same time, severely limiting the use environment of the carbon dioxide laser, thereby greatly limiting the scope of use of the carbon dioxide laser.

[0005] Therefore, based on the above, there is a great need for a carbon dioxide laser to solve the above problems. Summary of the invention

[0006] The object of the present invention is to provide a carbon dioxide laser with an adjustable support device to solve the problem that when the temperature near the connection between the gas storage pipe and one of the supporting feet changes rapidly in the prior art, one of the two supporting feet often breaks at the connection position with the water-cooling pipe or the gas storage pipe, resulting in the overall damage of the carbon dioxide laser. By setting a support device on the carbon dioxide laser that can adjust the relative distance between the two supporting feet, it is possible to avoid the situation where the carbon dioxide laser is damaged as a whole due to the unadjustable distance between the two supporting feet causing the connection between the supporting feet and the water-cooling pipe to break, thereby improving the yield rate of the carbon dioxide laser and greatly reducing the requirements for the use environment of the carbon dioxide laser.

[0007] To achieve the above object, the technical solution adopted by the present invention is as follows:

[0008] A carbon dioxide laser with an adjustable support device, comprising a water-cooling pipe and a gas storage pipe sleeved outside the water-cooling pipe. A first support assembly and a second support assembly are sequentially sleeved and connected outside the water-cooling pipe. The first support assembly and the second support assembly jointly support the water-cooling pipe. The first support assembly is supported and connected to the gas storage pipe through a first supporting foot, and the second support assembly is supported and connected to the gas storage pipe through a second supporting foot. The first support assembly can move relative to the second support assembly along the length direction of the water-cooling pipe.

[0009] In the carbon dioxide laser with an adjustable support device of the present invention, a first support assembly and a second support assembly are sequentially sleeved and connected outside the water-cooling pipe. Both the first support assembly and the second support assembly are used to support the water-cooling pipe to ensure that the gas storage pipe supports the water-cooling pipe.

[0010] The second support assembly is supported and connected to the gas storage pipe through a second supporting foot, that is, the second support assembly is connected to the gas storage pipe through the second supporting foot, and the second support assembly supports the gas storage pipe through the second supporting foot.

[0011] A first support assembly and a second support assembly are sequentially sleeved and connected outside the water-cooling pipe. The first support assembly can move relative to the second support assembly along the length direction of the water-cooling pipe. Specifically, the first support assembly is sleeved outside the water-cooling pipe and connected to the water-cooling pipe; the second support assembly is sleeved outside the first support assembly and connected to the first support assembly for support, but does not limit the relative displacement along the length direction of the water-cooling pipe. When the distance between the first supporting foot and the second supporting foot changes due to the deformation of the gas storage pipe, the first supporting foot drives the first support assembly, and the second supporting foot drives the second support assembly, thereby causing the first support assembly and the second support assembly to move relative to each other.

[0012] During the processing and use, when the temperature near the connection between the gas storage pipe and the first or second support feet changes rapidly, the corresponding part of the gas storage pipe will deform, which will cause the distance between the connection position of the first support foot and the gas storage pipe and the connection position of the second support foot and the gas storage pipe to change. At this time, the first support assembly supported and connected to the first support foot and the second support assembly supported and connected to the second support foot can move synchronously relative to the second support assembly along the length direction of the water-cooled pipe, avoiding the breakage of the connection between the first or second support foot and the gas storage pipe or the water-cooled pipe, thus avoiding the overall damage of the carbon dioxide laser caused by the breakage of the connection between the first or second support foot and the gas storage pipe or the water-cooled pipe, increasing the yield rate of the carbon dioxide laser. At the same time, the requirements for its use environment are reduced, and thus the use range of the carbon dioxide laser is greatly expanded.

The first support pipe is supported and connected to the water-cooled pipe through at least two first support members, and the first support pipe is supported and connected to the first support foot. The first support pipe can move relative to the second support assembly along the length direction of the water-cooled pipe.

[0016] In view of the problem in the prior art that the change in the distance between the first support foot and the second support foot will affect the deflection of the part of the water-cooled pipe between the first support foot and the second support foot, and further affect the output effect of the laser beam,

[0017] At least three first support members arranged at intervals along the length direction of the water-cooled pipe are provided between the first support pipe and the water-cooled pipe to reduce the influence of the relative movement of the first support pipe along the length direction of the water-cooled pipe with respect to the second support assembly on the deflection of the part of the water-cooled pipe between the first support foot and the second support foot, so as to ensure that the change in the deflection of the water-cooled pipe is within a controllable range, thereby ensuring the output effect of the laser.

[0018] Preferably, the bending stiffness of the first support pipe is greater than that of the water-cooled pipe.

[0060] Embodiment 1

[0061] As Figure 1 shown, a carbon dioxide laser with an adjustable support device includes a water-cooling tube 1 and a gas storage tube 2 sleeved outside the water-cooling tube 1. A first support assembly 3 and a second support assembly 4 are sequentially sleeved and connected outside the water-cooling tube 1. The first support assembly 3 and the second support assembly 4 jointly support the water-cooling tube 1. The first support assembly 3 is supported and connected to the gas storage tube 2 through a first support leg 5, and the second support assembly 4 is supported and connected to the gas storage tube 2 through a second support leg 6. The first support assembly 3 can move relative to the second support assembly 4 along the length direction of the water-cooling tube 1.

[0062] The first support assembly 3 is supported and connected to the gas storage tube 2 through the first support leg 5, that is, the first support assembly 3 is connected to the gas storage tube 2 through the first support leg 5, and the first support assembly 3 supports the gas storage tube 2 through the first support leg 5.

[0063] The second support assembly 4 is supported and connected to the gas storage tube 2 through the second support leg 6, that is, the second support assembly 4 is connected to the gas storage tube 2 through the second support leg 6, and the second support assembly 4 supports the gas storage tube 2 through the second support leg 6.

[0064] For the carbon dioxide laser with an adjustable support device of the present invention, a first support assembly 3 and a second support assembly 4 are sequentially sleeved and connected outside the water-cooling tube 1. Both the first support assembly 3 and the second support assembly 4 are used to support the water-cooling tube 1 to ensure that the gas storage tube 2 supports the water-cooling tube 1.

[0065] During processing and use, when the temperature near the connection between the gas storage pipe 2 and the first support leg 5 or the second support leg 6 changes rapidly, the corresponding part of the gas storage pipe 2 will be deformed, thereby causing the distance between the connection position of the first support leg 5 and the gas storage pipe 2 and the connection position of the second support leg 6 and the gas storage pipe 2 to change. At this time, the first support assembly 3 supported by the first support leg 5 and the second support assembly 4 supported by the second support leg 6 can move synchronously relative to each other along the length direction of the water-cooling pipe 1, thereby avoiding the connection position of the first support leg 5 or the second support leg 6 and the gas storage pipe 2 or the water-cooling pipe 1 from being broken, thereby avoiding the carbon dioxide laser from being damaged as a whole due to the connection position of the first support leg 5 or the second support leg 6 and the gas storage pipe 2 or the water-cooling pipe 1, thereby increasing the yield of the carbon dioxide laser and, at the same time, reducing the requirements of the carbon dioxide laser for its use environment, thereby greatly expanding the scope of use of the carbon dioxide laser.
