Abstract
Description
Technical Field
[0001] The utility model relates to a supporting device, in particular to a supporting bracket for a carbon dioxide laser tube and a carbon dioxide laser tube. Background Art
[0002] At present, the support structure used by carbon dioxide laser tubes at home and abroad is mostly to use glass columns at both ends to burn and connect the water cooling tube and the gas storage tube. Since the discharge tube and the water cooling tube are slender cylindrical structures, and the laser tube is generally installed horizontally in the external equipment, if only the two ends are connected to the gas storage tube through the support column, then under the influence of gravity for a long time, the middle position of the discharge tube and the water cooling tube is prone to bend downward, resulting in unstable laser tube beam and power reduction. At the same time, when the laser tube is impacted, the unsupported middle part of the discharge tube and the water cooling tube is more susceptible to being affected, and even directly deformed, thereby affecting the output power and output beam of the laser tube. And because the diameter of the water cooling tube and the diameter of the gas storage tube are quite different, that is, there is a large radial distance between the water cooling tube and the gas storage tube, it is necessary to set a longer leg, but the existing four-corner support bracket has a small cutting space and cannot produce legs of sufficient length. Utility Model Content
[0003] The purpose of the invention of the utility model is to provide a support bracket for a carbon dioxide laser tube and a carbon dioxide laser tube in view of the problems existing in the prior art.
[0004] In order to achieve the above purpose, the technical solution adopted by the utility model is:
[0005] A support bracket for a carbon dioxide laser tube comprises a cylinder, wherein three legs are arranged on the outer periphery of the cylinder, wherein at least one leg is an elastic leg, and the other legs are fixed legs, wherein the blade length of the elastic leg is greater than that of the fixed leg.
[0006] The cylinder of the support bracket of the utility model can be sleeved on the discharge tube / water cooling tube, and the legs can be supported on the water cooling tube / gas storage tube, so as to support the middle part of the discharge tube / water cooling tube, which can well offset the bending phenomenon of the laser tube discharge tube and the water cooling tube under the influence of gravity, improve the consistency of the central axis of the discharge tube, the water cooling tube and the central axis of the laser tube, and reduce the instability of the laser tube beam and the power drop caused by the bending of the discharge tube. In addition, when the laser tube is subjected to external impact, the support bracket can provide vertical support force to reduce the impact on the discharge tube and the water cooling tube.
[0007] In addition, compared with the four-corner support bracket, the three-leg design utilizes the stability principle of the triangle to improve the stability of the support bracket. It also saves more space and is easier to cut during production, so that each leg can be longer, meeting the requirements of a larger radial distance between the water cooling pipe and the gas storage pipe, and better offsetting the external impact force.
[0008] As a preferred solution of the utility model, one of the legs is an elastic leg, and the other two legs are fixed legs.
[0009] Since the blade length of the elastic leg is longer than that of the fixed leg, when only one leg is an elastic leg, the length of the elastic leg can be relatively longer, thereby meeting the requirement of a larger radial distance between the water cooling pipe and the gas storage pipe, and better offsetting the external impact force.
[0010] As a preferred solution of the utility model, two of the legs are elastic legs, and the remaining leg is a fixed leg.
[0011] As a preferred solution of the utility model, the blade of the elastic leg includes an arc section and a tilted section, one end of the arc section is connected to the outer periphery of the cylinder, and the other end is connected to the tilted section. The tilted section can cooperate well with the inner wall of the water cooling pipe / gas storage pipe, thereby improving the stability and reliability of the support bracket.
[0012] As a preferred solution of the utility model, one end of the arc section connected to the cylinder is provided with a protrusion section, which protrudes away from the cylinder. The protrusion section can enhance the fatigue resistance of the connection between the elastic leg and the cylinder and increase the service life of the support bracket.
[0013] As a preferred solution of the utility model, the cutting directions of the three legs are consistent, and the three legs are arranged on the same circular cross-section of the cylinder. The cutting directions of the three legs are consistent, which can maximize the length of the legs, and the three legs are arranged on the same circular cross-section of the cylinder, which can provide more stable support for the water cooling tube and the discharge tube, and improve the stability and reliability of the support bracket.
[0014] As a preferred solution of the utility model, the three legs are evenly arranged along the circumferential direction of the cylinder, so that the support bracket can provide relatively uniform support in the circumferential direction, thereby improving the stability and reliability of the support bracket.
[0015] As a preferred solution of the utility model, a barrel groove is provided on the outer periphery of the barrel, and the barrel groove is provided to penetrate along the axial direction of the barrel.
[0016] The utility model also discloses a carbon dioxide laser tube, comprising any one of the support brackets for the carbon dioxide laser tube, wherein the cylinder is sleeved on the outside of the water cooling tube, and the legs are supported on the gas storage tube.
[0017] The utility model also discloses a carbon dioxide laser tube, comprising any one of the support brackets for the carbon dioxide laser tube, wherein the cylinder is sleeved outside the discharge tube, and the legs are supported on a water cooling tube.
[0018] As a preferred solution of the utility model, along the axial direction of the water-cooling pipe, the number of the supporting brackets is at least 2.
[0019] In summary, due to the adoption of the above technical solution, the beneficial effects of the utility model are:
[0020] 1. The cylinder of the support bracket of the utility model can be sleeved on the discharge tube / water cooling tube, and the legs can be supported on the water cooling tube / gas storage tube, so as to support the middle part of the discharge tube / water cooling tube, which can well offset the bending phenomenon of the laser tube discharge tube and the water cooling tube under the influence of gravity, improve the consistency of the central axis of the discharge tube, the water cooling tube and the central axis of the laser tube, and reduce the instability of the laser tube beam and the power drop caused by the bending of the discharge tube. In addition, when the laser tube is subjected to external impact, the support bracket can provide vertical support force to reduce the impact on the discharge tube and the water cooling tube.
[0021] 2. Compared with the four-corner support bracket, the three-leg design utilizes the stability principle of the triangle to improve the stability of the support bracket. It also saves more space and is easier to cut during production, so that each leg can be longer, meeting the requirement of a larger radial distance between the water cooling pipe and the gas storage pipe, and better offsetting the external impact force.

[0036] Example 1
[0037] like Figure 1-Figure 4 As shown, a support bracket for a carbon dioxide laser tube includes a barrel 1 and a support leg 2.
[0038] The cylinder 1 is generally a cylindrical structure with two ends passing through. The cylinder 1 can be sleeved on the outside of the water-cooling tube of the laser tube. In some other embodiments, the cylinder 1 can also be sleeved on the outside of other structural parts of the laser tube, for example, on the outside of the discharge tube of the laser tube, or on the outside of other additional structural tubes / layers.
[0039] The cylinder 1 can be made of elastic metal, which can meet the elasticity requirements, is easy to manufacture and process, and can also meet the working conditions of the carbon dioxide laser tube. More preferably, the cylinder 1 can be made of titanium metal to better meet the working conditions of the carbon dioxide laser tube.
[0040] In one or more embodiments, a barrel groove 11 may be provided on the outer periphery of the barrel 1, and the barrel groove 11 may be provided along the axial direction of the barrel 1. The barrel groove 11 is usually a linear groove, and in some other embodiments, a curved groove may be used as the barrel groove 11.
[0041] Since the support bracket has a certain elasticity, the barrels 1 on both sides of the barrel groove 11 are usually overlapped when the support bracket is not stressed, and after the support bracket is sleeved on the water-cooling pipe and other structures, the barrels 1 on both sides of the barrel groove 11 will open, thereby exposing the barrel groove 11. Therefore, the setting of the barrel groove 1 facilitates the opening or compression of the barrel 1, facilitates the installation of the support bracket, and can improve the stability of the support bracket sleeved on the water-cooling pipe and other structures.
[0042] The three legs 2 are arranged on the outer periphery of the cylinder 1, one end of each leg 2 is connected to the cylinder 1, and extends in a direction away from the cylinder 1 to form a support end, which can be supported by the gas storage pipe. In some other embodiments, the support end can also be supported by other structural parts of the laser tube, such as a water cooling tube of the laser tube or other additional structural tubes / layers.
[0043] In one or several embodiments, the cutting directions of the three legs 2 can be consistent, that is, the extending directions of the three legs 2 are consistent, for example, the three legs 2 are all extended in a clockwise direction or the three legs 2 are all extended in a counterclockwise direction. In this way, the cutting space can be increased as much as possible, the length of the legs can be increased, and a better elastic support effect can be achieved.
[0044] In one or more embodiments, the three legs 2 are arranged on the same circular cross section of the cylinder 1, that is, the three legs 2 are on the same circumference. In this way, the stability and reliability of the support bracket can be improved, and a more stable support can be provided for the water-cooling tube and the discharge tube. Furthermore, the three legs 2 can be evenly arranged along the circumferential direction of the cylinder 1. Thereby, the support bracket can provide relatively uniform support in the circumferential direction, further improving the stability and reliability of the support bracket.
[0045] One of the three legs 2 is an elastic leg 21, and the other two legs 2 are fixed legs 22. The blade length of the elastic leg 21 is greater than that of the fixed leg 22, and the elastic deformation ability of the elastic leg 21 is stronger than that of the fixed leg 22. In this way, the elastic leg 21 mainly plays an elastic supporting role, and the fixed leg 22 mainly plays a positioning and supporting role. In this scheme, since there is only one elastic leg 21, the cutting space of the elastic leg 21 can be increased as much as possible, and the length of the elastic leg 21 can be increased, so that it is suitable for the water-cooling tube and the gas storage tube with a larger tube diameter difference, and of course it can also be suitable for the discharge tube and the water-cooling tube. And because two fixed legs are provided, it is also easier to install, and it is convenient to determine the axis during installation, and improve the consistency of the central axis of the discharge tube, the water-cooling tube and the central axis of the laser tube.
[0046] The blade of the elastic leg 21 includes an arc segment 211 and a tilted segment 212, one end of the arc segment 211 is connected to the outer periphery of the cylinder 1, and the other end is connected to the tilted segment 212. The tilted segment 212 can cooperate well with the inner wall of the structure such as the gas storage pipe, thereby improving the stability and reliability of the support bracket.
[0047] In one or more embodiments, one end of the arc segment 211 connected to the cylinder 1 is provided with a protruding segment 213, and the protruding segment 213 protrudes away from the cylinder 1. The protruding segment 213 can enhance the fatigue resistance of the connection between the elastic leg 21 and the cylinder 1 and increase the service life of the support bracket.
[0048] In one or more embodiments, the arc segment 211, the tilted segment 212, and the protruding segment 213 are integrally formed structural parts. Further, the elastic legs 21, the fixed legs 22 and the cylinder 1 are integrally formed structural parts, that is, the legs 2 are also made of elastic metal, more preferably titanium metal. The legs 2 are formed by cutting and bending the cylinder 1, which is more convenient for manufacturing and processing.
[0049] Example 2
[0050] The difference between this embodiment and embodiment 1 is that in this embodiment, two of the legs 2 are elastic legs 21, and the remaining leg 2 is a fixed leg 22. In this way, the supporting function of the support bracket can also be achieved. And because two elastic legs 21 are provided, the elasticity of the support bracket is relatively large, and a better elastic supporting effect can be provided. The support bracket of this embodiment can be applied between the discharge tube and the water cooling tube, or between the water cooling tube and the gas storage tube.

[0053] The cylinder 1 is sleeved on the outside of the water-cooling pipe, that is, the cylinder 1 can be directly sleeved on the water-cooling pipe, or a structural pipe / layer can be additionally arranged on the outer periphery of the water-cooling pipe, and the cylinder 1 is sleeved on the structural pipe / layer.
[0054] The supporting legs 2 are supported on the gas storage pipe, that is, the supporting legs 2 can be directly supported on the gas storage pipe, or a structural pipe / layer can be additionally provided on the inner periphery of the gas storage pipe, and the supporting legs 2 are supported on the structural pipe / layer.
[0055] Furthermore, in order to improve the stability of the support, the number of the support brackets is at least 2 along the axial direction of the water-cooling pipe, for example, the two support brackets are respectively located at 1 / 3 and 2 / 3 of the length of the water-cooling pipe.

That is, support brackets may be provided between the discharge tube 3 and the water cooling tube 4, and between the water cooling tube 4 and the gas storage tube 5 at the same time.
[0062] In this way, the middle parts of the discharge tube 3 and the water-cooling tube 4 can be better supported, which can effectively offset the bending phenomenon of the laser tube discharge tube 3 and the water-cooling tube 4 under the influence of gravity, improve the consistency of the central axis of the discharge tube 3 and the water-cooling tube 4 with the central axis of the laser tube, and reduce the instability of the laser tube beam and the power drop caused by the bending of the discharge tube.
[0063] The cylinder 1 is sleeved on the outside of the water-cooling tube 4, that is, the cylinder 1 can be directly sleeved on the water-cooling tube 4, or a structural tube / layer can be additionally arranged on the outer periphery of the water-cooling tube 4, and the cylinder 1 is sleeved on the structural tube / layer.
