Description

Technical Field

[0001] The utility model relates to the technical field of welding positioning, in particular to a positioning structure of a laser welding device. Background Technique

[0002] Laser welding is a welding technology that uses a high-power laser beam to melt metal materials. This technology has many advantages, such as high energy density, fast heating and cooling processes, small heat-affected zones, and good welding depth-to-width ratios. These advantages make laser welding very useful in many fields, especially in industries such as automotive, aerospace, electronics, and medical device manufacturing. When using a laser welding device, a positioning structure is required to position the items to be welded. The positioning structure is a structure in mechanical design used to fix and support workpieces or components to ensure that they maintain the correct position during processing, assembly, or other operations.

[0003] When welding tubular items, a positioning device is needed to align the two pipes before welding. However, when the existing positioning structure positions the pipes, it cannot flip the pipes. After welding the upper surface, the pipes need to be disassembled and fixed again to flip the pipes, so as to complete the welding of the lower surface, resulting in low work efficiency. In addition, the existing positioning structure cannot position pipes of different sizes. When it is necessary to position pipes of different sizes, different molds need to be replaced, which is rather troublesome. Therefore, a positioning structure of a laser welding device is proposed for the above problems. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a positioning structure of a laser welding device to solve the problems of inability to flip the pipes and inability to position pipes of different sizes proposed in the above background technique.

[0022] Please refer to Figures 1-4 , the present invention provides a technical solution:

[0023] A positioning structure of a laser welding device, including a bottom plate 1. In the middle of the top end of the bottom plate 1, a horizontally arranged slide rail 2 is fixedly connected. A horizontally arranged through groove 3 that communicates with the inner side of the slide rail 2 is opened on the front side of the slide rail 2. Symmetrically arranged sliders 4 are slidably connected inside the slide rail 2. A horizontally arranged threaded rod 5 located inside the through groove 3 is fixedly connected to the front side of the slider 4. A threaded cylinder 6 located on the front side of the slide rail 2 is spirally connected to the outside of the threaded rod 5. A vertically arranged fixed rod 7 is fixedly connected to the top end of the slider 4. A horizontally arranged connecting rod 8 is fixedly connected to the top end of the fixed rod 7. One end of the connecting rod 8 is fixedly connected to a bearing 9. One end of the bearing 9 away from the connecting rod 8 is fixedly connected to a fixed cylinder 10. A threaded column 11 that penetrates the fixed cylinder 10 is spirally connected to the outside of the fixed cylinder 10. One end of the threaded column 11 is rotatably connected to a pressing ring 12 located inside the fixed cylinder 10. A limiting component 13 is arranged on one side of the fixed cylinder 10. A supporting device 14 is arranged on the top end of the slide rail 2.

[0024] The limiting component 13 includes a limiting hole 1301 opened on the side of the fixed cylinder 10 close to the connecting rod 8. A disc 1302 is fixedly connected to the end of the connecting rod 8 away from the bearing 9. A horizontally arranged limiting rod 1303 that penetrates the disc 1302 is slidably connected inside the disc 1302. A baffle 1304 is fixedly connected to the outside of the limiting rod 1303. A spring 1305 located on the outside of the limiting rod 1303 is fixedly connected to one end of the baffle 1304. A handle 1306 is fixedly connected to the end of the limiting rod 1303 away from the fixed cylinder 10. The setting of the limiting component 13 enables the operator to weld the unwelded area without disassembling the pipeline. The number of the limiting holes 1301 is multiple, and the limiting holes 1301 are arranged in an array on the side of the fixed cylinder 10 close to the connecting rod 8. The limiting rod 1303 is located inside two of the limiting holes 1301. The end of the spring 1305 away from the baffle 1304 is fixedly connected to the disc 1302. The setting of multiple limiting holes 1301 enables the pipeline to complete rotations at different angles. The supporting device 14 includes a supporting cylinder 1401 that is vertically arranged and fixedly connected to the top end of the slide rail 2. A supporting rod 1402 is slidably connected inside the supporting cylinder 1401. A connecting plate 1403 is fixedly connected to the outside of the supporting cylinder 1401. A bolt 1404 that penetrates the connecting plate 1403 is spirally connected to the inside of the connecting plate 1403. The top end of the bolt 1404 is rotatably connected to a supporting ring 1405. The supporting device 14 can support the pipeline to prevent positioning loosening caused by the overweight of the pipeline. The connection mode between the pressing ring 12 and the fixed cylinder 10 is a sliding connection. The top end of the supporting rod 1402 is fixedly connected to the bottom end of the supporting ring 1405.

[0025] Workflow: When the pipeline needs to be positioned, first place the two pipelines inside the two pressing rings 12 inside the fixing cylinder 10 respectively. Then turn the threaded column 11. Due to the limitation of the fixing cylinder 10 on the threaded column 11, the threaded column 11 can drive the pressing ring 12 to slide inside the fixing cylinder 10 until the pressing ring 12 is in close contact with the outer side of the pipeline. Then turn the bolt 1404 at the bottom of the support ring 1405. Due to the limitation of the connecting plate 1403, the bolt 1404 drives the support ring 1405 to move upward, and the support rod 1402 slides inside the support cylinder 1401 until the support ring 1405 is in close contact with the outer side of the pipeline. The support device 14 can support the pipeline to prevent the positioning from loosening due to the excessive weight of the pipeline. Next, loosen the threaded cylinder 6 and move the slider 4 at the bottom of the fixed rod 7. At this time, the slider 4 slides inside the slide rail 2 on the top of the bottom plate 1, and the threaded rod 5 slides inside the through groove 3. When the two pipelines are aligned, tighten the threaded cylinder 6 to complete the fixation of the pipeline. After welding the upper half of the pipeline, pull the handle 1306. At this time, the limiting rod 1303 slides inside the disc 1302 and disengages from the limiting hole 1301, and the spring 1305 on one side of the baffle 1304 is compressed. Then rotate the pipeline so that the fixing cylinder 10 rotates on the side of the bearing 9 on one side of the connecting rod 8, and rotate the unwelded area of the pipeline upward. Release the handle 1306, and the spring 1305 resets to drive the limiting rod 1303 to slide inside the disc 1302 and insert into the limiting hole 1301, thus completing the flipping and positioning of the pipeline. The limiting component 13 enables the pipeline to rotate at different angles, and the unwelded area can be welded without disassembling the pipeline.
