Description

Technical Field

[0001] The utility model relates to the technical field of laser welding, in particular to a laser welding gun pipeline structure. Background Art

[0002] In laser welding technology, the traditional laser welding gun pipeline structure usually contains multiple independent pipelines, which are used for the layout of air pipes and fiber optic tubes respectively. The fiber optic tube is composed of a fiber optic bundle and is used to accurately transmit the laser beam from the laser generator to the welding head to ensure the accuracy and efficiency of laser welding. The air pipe is used to transport auxiliary gases, such as nitrogen, argon and other protective gases, as well as gases used to cool the welding area; these gases play a vital role in the welding process. They can prevent the welding area from being oxidized and reduce the occurrence of welding defects. At the same time, they also help to cool the welding area and improve the welding quality and stability.

[0003] However, in the prior art, the gas pipe and the optical fiber pipe use different pipeline designs. Although this practice ensures the independence of their respective functions to a certain extent, it also brings many problems. First, the existence of multiple pipelines increases the complexity of the welding gun structure, making the overall volume of the equipment bulky and not conducive to movement and carrying; secondly, the arrangement of multiple pipelines also increases the risk of pipeline breakage. Once the pipeline is damaged, it will directly affect the smooth progress of the welding process and reduce the reliability and universality of the machine.

[0004] Therefore, in view of this, the inventor proposes a laser welding gun pipeline structure to solve the above problems. Utility Model Content

[0041] This embodiment proposes a laser welding torch pipeline structure, as Figures 1 to 11 shown, including pipeline 1 and optical fiber tube 2. Pipeline 1 has a hollow structure, and optical fiber tube 2 is arranged inside pipeline 1. An air flow cavity 3 is formed between the inner wall of pipeline 1 and the outer wall of optical fiber tube 2.

[0042] An air inlet 4 and an air outlet 5 are arranged on pipeline 1. The air inlet 4 is used to introduce external gases, and the air outlet 5 is used to discharge the gases from the air flow cavity 3. Both the air inlet 4 and the air outlet 5 are connected to the air flow cavity 3 to ensure the smooth flow of gases

[0043] As a preferred embodiment, pipeline 1 includes an optical fiber rod body 11, an air pipe 12, and an armor adapter 13. One end of the air pipe 12 (i.e., Figure 2 the left end of the air pipe 12 in Figure 2The right end of the middle gas pipe 12 is connected to the armor adapter 13. This design allows the pipeline 1 to form a complete gas flow path. At the same time, the optical fiber tube 2 is arranged in the pipeline 1 to provide protection for the optical fiber tube 2.

[0044] The optical fiber rod body 11 is provided with a first installation cavity 111 and an air outlet cavity 112. One end of the optical fiber tube 2 is installed in the first installation cavity 111 and passes through the first installation cavity 111, and the air outlet cavity 112 is connected to the first installation cavity 111. The air outlet cavity 112 is connected to the air flow cavity 3 to guide the gas from the air flow cavity 3 to the welding area (not shown) through the air outlet cavity 112. The air outlet 5 is provided on the optical fiber rod body 11 and is connected to the air outlet cavity 112 to ensure the smooth discharge of the gas.

[0045] In order to facilitate installation and disassembly, a first connecting piece 113 is provided on one side of the optical fiber rod body 11. The first connecting piece 113 can be inserted into the trachea 12 or pulled out from the trachea 12, thereby realizing a detachable connection between the optical fiber rod body 11 and the trachea 12. This design is not only convenient for replacement and maintenance, but also improves the flexibility and reliability of the entire pipeline structure.

[0046] A second installation cavity 131 and an air inlet cavity 132 are provided in the armor adapter 13. The other end of the optical fiber tube 2 is installed in the second installation cavity 131 and passes through the second installation cavity 131, while the air inlet cavity 132 is communicated with the second installation cavity 131. The air inlet cavity 132 and the air flow cavity 3 are communicated with each other for introducing external gas into the air flow cavity 3. The air inlet 4 is provided on the armor adapter 13 and is communicated with the air inlet cavity 132, thereby ensuring the smooth introduction of gas.

[0047] Similarly, in order to facilitate installation and disassembly, a second connecting piece 133 is also provided on one side of the optical fiber rod body 11. The second connecting piece 133 can be inserted into the trachea 12 or pulled out from the trachea 12, thereby realizing a detachable connection between the optical fiber rod body 11 and the trachea 12. This design further improves the flexibility and reliability of the entire pipeline structure.

[0048] As a preferred embodiment, a first quick connector 6 is provided on the gas outlet 5, and the first quick connector 6 is convenient for quick connection and disconnection with an external gas supply source, thereby improving the convenience and practicality of the entire pipeline structure; at the same time, a fiber optic holder 10 is also provided on the fiber optic rod body 11, and a PU tube 7 is connected to the fiber optic holder 10, and the other end of the PU tube 7 is connected to the first quick connector 6, thereby forming a complete gas delivery system.

The sheath 21 is tightly sleeved on the outer wall of the optical fiber 22, providing good protection and support for the optical fiber 22. The material of the sheath 21 can be selected according to actual needs to ensure good wear resistance, corrosion resistance and high temperature resistance.

[0050] To ensure the gas tightness, sealant 8 is coated between the first installation cavity 111 and the second installation cavity 131 and the optical fiber tube 2; that is to say, when both ends of the sheath 21 are installed in the first installation cavity 111 and the second installation cavity 131, the outer wall of the sheath 21 is coated with sealant 8. The sealant 8 can effectively prevent gas leakage and improve the reliability and stability of the entire pipeline structure.

[0051] In addition, a second quick connector 9 is also provided on the air inlet 4. The second quick connector 9 is also convenient for quickly connecting and disconnecting with an external gas supply source, thereby further improving the convenience and practicality of the entire pipeline structure.

[0052] In the specific use process, the user can connect an external gas supply source to the air inlet 4 through the second quick connector 9, and then turn on the gas supply source to introduce the gas into the air flow cavity 3. When the gas flows in the air flow cavity 3, it will pass through the outer wall of the optical fiber tube 2 and cool and protect it. At the same time, part of the gas will be discharged to the optical fiber seat 10 through the air outlet 5 and the first quick connector 6, and then the optical fiber seat 10 is connected to a pipeline, and the gas is transported through the pipeline to the welding area to provide necessary shielding gas or cooling gas for the welding process.

[0053] In the present utility model, by providing a hollow pipeline 1 and an optical fiber tube 2 disposed inside the pipeline 1, an air flow cavity 3 is formed between the inner wall of the pipeline 1 and the outer wall of the optical fiber tube 2. This air flow cavity 3 is used to transport shielding gas; an air inlet 4 and an air outlet 5 are provided on the pipeline 1, and both of these ports are communicated with the air flow cavity 3, enabling the gas to flow in and out smoothly. Integrating the air pipe 12 and the optical fiber tube 2 into a single pipeline 1 structure simplifies the structure and improves portability and reliability, reduces the number of pipelines, reduces the complexity of the structure, and also reduces the risk of pipeline breakage caused by the redundancy of multiple pipelines, facilitating use, with a compact structure and strong practicality.
