[0002] Laser welding is a high-efficiency welding method. Applying the laser welding process to build ships has the advantages of high welding quality, high welding efficiency, and low welding cost. When laser welding, after welding one side, the steel plate often needs to be turned over, the part of the back weld that has just been welded is planed off, and then this side is welded again. The reason for this is that during laser welding, the back of the welded joint has no medium protection, resulting in the invasion of harmful gases around the back weld metal, affecting the weld quality. Since it is necessary to plane the seam and weld the back after welding the front, the welding efficiency is greatly affected. Therefore, a laser welding gasket is needed.
[0003] However, the existing laser welding gaskets are not convenient to disassemble and install, have no anti-scald structure, and the selection surface type for welding is single. Content of the Utility Model
[0004] The purpose of the utility model is to provide a laser welding gasket to solve the problems raised in the above background technique.
[0005] To achieve the above purpose, the utility model provides the following technical solution: a laser welding gasket, including: a base, a mounting plate, and a suction cup. Mounting plates are fixedly installed on both the left and right sides of the base, suction cups are fixedly installed at both the front and rear ends of the mounting plate, an outer shell is installed on the outside of the base, and a heat insulation layer is installed between the base and the outer shell;

DETAILED DESCRIPTION OF THE EMBODIMENTS
[0020] In order to clearly and completely describe the purpose and technical solution of the present utility model, and make the advantages more clear, the following further details the embodiments of the present utility model with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are some embodiments of the present utility model, rather than all embodiments, and are only used to explain the embodiments of the present utility model, not to limit the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present utility model.
[0021] Please refer to Figures 1 - 4, the present utility model provides a technical solution: a laser welding gasket, comprising: a base 2, a mounting plate 4 and a suction cup 5. The mounting plates 4 are fixedly installed on both the left and right sides of the base 2, and the suction cups 5 are fixedly installed at both the front and rear ends of the mounting plate 4. The suction cup 5 is a vacuum suction cup, which can adsorb on the back of the object to be welded, align the reference line 16 on the gasket 6 with the weld seam at the same time, and also fix the object to be welded. The reference line 16 is beneficial to improving the welding accuracy and welding quality. An outer shell 1 is installed outside the base 2, and a heat insulation layer 3 is installed between the base 2 and the outer shell 1. The heat insulation layer 3 is made of heat insulation material, with good heat insulation, insulation and high temperature resistance. It can avoid the heat on the surface after welding from dissipating and causing the outer wall of the equipment to heat up, scalding the operator, and improving the safety performance.
[0022] The gasket 6 is detachably installed inside the upper end of the base 2. The reference line 16 is arranged at the centers of the front and rear sides of the upper end of the gasket 6. The upper end of the gasket 6 is a plane or an arc-shaped groove 17 is opened at the upper end of the gasket 6. When the upper end of the gasket 6 is a plane, the reference line 16 is opened on the upper end of the gasket 6. When the arc-shaped groove 17 is opened at the upper end of the gasket 6, the reference line 16 is opened on the inner wall of the bottom end of the arc-shaped groove 17. The reference line 16 is beneficial to improving the welding accuracy and welding quality. There is no medium protection on the back of the traditional welding joint, and it is easy to slag off. The gasket 6 plays a role in plugging and protecting the weld seam, making the weld seam uniform and smooth after forming, which is beneficial to improving the welding efficiency. If a convex weld seam on the back is required, the gasket 6 with an arc-shaped groove 17 can be installed in the base 2, and the arc-shaped groove 17 is used to realize the convexity on the back of the welding. The surface of the arc-shaped groove 17 is smooth and easy to demold after forming. After the welding is completed, the air valve of the suction cup 5 is opened, and the base 2 can be detached, and thus the use process of the entire laser welding gasket is completed.
[0023] Connecting plates 9 are symmetrically and fixedly installed on the side walls of the left and right sides of the inner end of the base 2. The telescopic rods 10 are fixedly installed at the upper ends of the connecting plates 9. A first spring 11 is sleeved on the outer wall of the telescopic rod 10. Connecting strips 7 are arranged on both the left and right sides of the lower end of the gasket 6. The connecting strip 7 is L-shaped. One end of the connecting strip 7 is fixedly installed at the lower end of the gasket 6, and a limiting hole 8 is opened on the lower side of one end of the connecting strip 7. When installing the gasket 6, the gasket 6 is slid into the inner side of the base 2 and pressed down. The other end of the connecting strip 7 contacts the upper end of the telescopic rod 10 and moves downward by compressing the first spring 11 until the inner end of the limiting rod 13 is inserted into the limiting hole 8, thereby fixing the gasket 6.
[0024] Through holes 12 are provided on the side walls at the left and right ends of the outer shell 1, the base 2, and the heat insulation layer 3. The through holes 12 are located at the lower end of the mounting plate 4. A limiting rod 13 is slidably connected in the through holes 12. A slope is provided at the inner end of the limiting rod 13, and a pull rod 14 is fixedly installed at the outer end. A second spring 15 is sleeved on the outer wall of the limiting rod 13. One end of the second spring 15 is fixedly installed on the outer wall of the outer shell 1, and the other end is fixedly installed on the side wall of the pull rod 14. When the second spring 15 is in a balanced state, the inner end of the limiting rod 13 is inserted into the limiting hole 8 to fix the gasket 6. When the gasket 6 needs to be replaced, by pulling the pull rod 14 outward, the limiting rod 13 moves outward by stretching the second spring 15 until it slides out of the limiting hole 8. Under the reaction force of the first spring 11, the gasket 6 is pushed out of the outside of the base 2, which facilitates the replacement of the gasket 6.
[0025] During actual use, by adsorbing the suction cup 5 on the back of the object to be welded, and at the same time aligning the reference line 16 on the gasket 6 with the weld seam, welding can be carried out. If a convex weld seam on the back is required, a gasket 6 with an arc-shaped groove 17 can be installed in the base 2, and the arc-shaped groove 17 is used to achieve a convex back during welding. The surface of the arc-shaped groove 17 is smooth and easy to demold after forming. After welding is completed, the air valve of the suction cup 5 is opened, and the base 2 can be detached. In this way, the use process of the entire laser welding gasket is completed.
