Description

Technical Field

[0001] This invention patent relates to the field of laser additive welding machines, and specifically to a laser additive welding machine. Background Art

[0002] Laser additive is a process method that uses the arc heat effect generated by welding equipment to locally heat and melt the cross-section of the metal to be welded to a liquid state, so that the originally separated metals are combined into a firm and non-detachable joint. Due to the high temperature and strong radiation of the arc light, it will also cause toxic gases such as ozone and nitrogen oxides to be generated in the surrounding air, and it will also affect the operator's line of sight during welding work.

[0003] When processing some metal parts, it is necessary to connect multiple metal parts. When connecting, it is necessary to connect them by bolts or by laser welding. However, when connecting multiple metal parts that do not need to be disassembled later, welding is mostly used for connection. When welding with a laser additive welding machine, the surface of the laser oxidation welding metal material can be quickly heated to the ignition temperature under the irradiation of the laser beam of the laser additive welding machine, and then undergo a combustion reaction with oxygen, releasing a large amount of heat, forming small holes inside the material. The small holes are surrounded by a molten metal wall. These vapors and molten substances are carried away by the auxiliary air flow and then float in the factory workshop, forming dust and smoke. Therefore, when using a welding machine for welding, it is easy to form dust or smoke, and the smoke enters the air.

[0004] Therefore, when using a laser additive welding machine, a large amount of smoke will be generated. When the smoke is dispersed, it will be scattered inside the factory. However, some existing laser additive welding machines usually only have the function of welding metals. However, the smoke generated during welding will be dispersed in the air, and thus the smoke formed by laser welding cannot be well treated, resulting in the smoke entering the air and being scattered inside the factory, which will cause harm to the physical health of the staff.

[0018] The following details the present invention, clearly and completely describing the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0019] The present invention provides a laser welding by improvement. The technical solution of the present invention is: AsFigure 1 - Figure 7 As shown in Figure 7 , a laser additive welding machine includes a workbench 1. A welding machine 2 is arranged on the upper surface of the workbench 1. A smoke suction machine outer cover 3 is fixedly connected to the lower surface of the welding machine 2. The inner wall of the smoke suction machine outer cover 3 is trapezoidally arranged. By arranging the inner wall of the smoke suction machine outer cover 3 in a trapezoid shape, it can provide a larger moving space for the welding machine 2 during laser welding, and can also better enable the staff to clearly see the working state of the laser additive welding machine.

[0020] A suction fan 4 is arranged at the upper right of the workbench 1. The air suction end of the suction fan 4 is communicated with a pipeline 5. The other end of the pipeline 5 is communicated with the smoke suction machine outer cover 3. The pipeline 5 is a flexible pipe and is matched with the welding machine 2. By matching the pipeline 5 with the welding machine 2, during the operation of the welding machine 2, it can move along with the welding machine 2, improving the connection between the welding machine 2 and the filtering device during the operation of the staff.

[0021] The side wall of the workbench 1 is fixedly connected with an outer cover 6. The air outlet end of the pipeline 5 is communicated with a first steel pipe 7. The bottom end of the first steel pipe 7 penetrates through the upper surface of the outer cover 6. The surface of the first steel pipe 7 is fixedly connected with the inner wall of the outer cover 6. The inner wall of the outer cover 6 is fixedly connected with a water storage and filtering barrel 8. The bottom end of the first steel pipe 7 penetrates through the upper end of the water storage and filtering barrel 8 and extends into the interior of the water storage and filtering barrel 8. By sending the harmful gases generated during welding into the water storage and filtering barrel 8 through the bottom end of the first steel pipe 7 penetrating through the upper end of the water storage and filtering barrel 8 and extending into the interior of the water storage and filtering barrel 8 for the first filtration, the harmful gases can obtain a certain filtration effect.

[0022] The upper end of the water storage and filtering barrel 8 is communicated with a second steel pipe 9. The inner wall of the outer cover 6 is fixedly connected with a filtering box 10. The other end of the second steel pipe 9 is communicated with the upper surface of the filtering box 10. Two symmetrically arranged first grooves 11 are formed in the inner wall of the filtering box 10. A gear 12 is rotatably connected to the inner wall of the first groove 11. Two openings 13 communicated with the first grooves 11 are formed in the front side wall of the filtering box 10. Two gear racks 14 are meshed with the gear 12. A second groove plate 15 is fixedly connected to the side walls of the two gear racks 14. The surface of the second groove plate 15 is slidably connected with the inner wall of the opening 13. A filter screen 16 is placed in the second groove plate 15. The inner wall of the second groove plate 15 is L-shaped and is matched with the filter screen 16. The L-shaped inner wall of the second groove plate 15 can make the filter screen 16 be placed more stably in the second groove plate 15.

[0023] Furthermore, a clamp 17 is arranged on the upper surface of the workbench 1 and is matched with the welding machine 2. By arranging the clamp 17 on the upper surface of the workbench 1, the steel pipe to be welded can be clamped and fixed. The clamp 17 being matched with the welding machine 2 is convenient for operation and improves the precision of the steel pipe to be welded during the welding work.

[0024] The jig 17 is a prior art and is well-known to those skilled in the art. Therefore, it is not described in detail in the original text.

[0025] Working principle: When the laser additive welding machine is working, welding is performed by the welding machine 2 on the object workbench 1. There is a fume hood 3 above the welding machine 2. When high-temperature welding is performed, harmful gases generated will be sucked from the fume hood 3 into the exhaust fan 4 through the pipeline 5 during the operation of the exhaust fan 4. Then, the exhaust fan 4 sends the harmful gases through the first steel pipe 7 into the water storage and filtration barrel 8 for the first filtration. After the first filtration, the filtered gas is discharged through the second steel pipe 9 above the water storage and filtration barrel 8 to the filter screen 16 in the filtration box 10 for the second filtration. The second groove plate 15 can slide through the rack 14 and the gear 12 to slide the second groove plate 15 out of the opening 13, and the groove plate parallel to it will let the new filter screen 16 enter the filtration box 10 through the opening 13 to achieve the connection of the replacement of the filter screen 16.

[0026] The above description enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be obvious to those skilled in the art. The general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to these embodiments shown herein, but rather to the broadest scope consistent with the principles and novel features disclosed herein.
