Description

Technical Field

[0001] The utility model relates to the technical field of welding, in particular to an electromagnetic-assisted welding device. Background Art

[0002] Laser welding is an important field of laser technology application. It has the advantages of small heat input, high welding precision, low residual stress, large depth-width ratio, easy automation control, etc., and thus has been widely developed and applied. Especially in the welding field of difficult-to-weld materials and special structures, it has been successfully applied in manufacturing fields such as aviation, aerospace, automobiles, shipbuilding, electronics, nuclear power, etc., and has received great attention from countries around the world. With the rapid development of the world's industrial technology, in the high-quality and high-precision manufacturing fields under extreme conditions such as nuclear power equipment, aerospace, and ocean engineering, the demand for thick plate welding structures is increasing, the thickness is also increasing, and the types of materials are also showing a trend of diversification.

[0003] According to a disclosed electromagnetic field-assisted laser welding device (publication number: CN 209919102 U), among them, there are two magnets, which are installed in parallel in the grooves of a horizontally placed welding fixture. The workpiece is between the two magnets and is clamped and positioned by the welding fixture; the positive and negative electrodes of the current generator are connected to the welding seams at the front and rear ends of the workpiece through clip pieces; the laser head of the laser system is connected to the air nozzle of the auxiliary gas supply component, and the air nozzle is aligned with the weld seam of the workpiece. By the current provided by the current generator acting on the molten pool of the workpiece, the workpiece to be welded is subjected to the action of a stable electromagnetic force in a steady magnetic field. Based on this electromagnetic force and using the laser system to control the air nozzle to weld thick plates, the weld seam will no longer collapse, and there will be no hump or wine glass-shaped weld seam after the weld seam is formed, thus ensuring the quality of the weld seam formation. However, the above application cannot fix welding workpieces of different sizes during use, and welding slag will remain on the operation platform during welding. Summary of the Utility Model

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0022] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings 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 shall fall within the protection scope of the present invention.

[0023] As Figures 1-4 shown, the present invention provides a technical solution: an electromagnetic assisted welding device.

[0024] It includes a welding table 1, a limiting block 2 is fixedly connected to the bottom of the welding table 1, a support column 3 is fixedly connected to the top of the welding table 1, a fixing plate 4 is fixedly connected to the top of the support column 3, a control module 5 is fixedly connected to the bottom of the fixing plate 4, an electric welding gun 6 is slidably and electrically connected to the bottom of the control module 5, and a clamping and cleaning device 7 and a collection and alarm device 8 are arranged on the welding table 1;

[0025] The clamping and cleaning device 7 includes an electric cylinder 71, an electric push rod 72 is slidably and electrically connected to the side of the electric cylinder 71, a clamping block one 73 is fixedly connected to the side of the electric push rod 72 away from the electric cylinder 71, a rack one 74 is fixedly connected to the bottom of the clamping block one 73, a gear 75 is arranged above the rack one 74, the gear 75 is fixedly connected to the outside of a rotating rod 76, a rack two 77 is arranged above the gear 75, a clamping block two 78 is fixedly connected to the top of the rack two 77, a piston rod 79 is fixedly connected to the side of the clamping block two 78, the side of the piston rod 79 away from the clamping block two 78 is slidably connected inside an air storage block 710, a gas one-way valve 711 is fixedly connected to the side of the air storage block 710, piston air valves 712 are arranged on both sides of the air storage block 710, a top block 713 is arranged on the side of the piston air valve 712, and telescopic spray air pipes 714 are fixedly connected to both sides of the air storage block 710.

[0026] As Figure 2 shown, a collection groove and a limiting groove are formed on the welding table 1, and the electric cylinder 71 and the air storage block 710 are fixedly connected to the bottom of the welding table 1.

[0027] The collection groove on the welding table 1 can effectively collect the welding slag generated by welding, and the limiting groove can effectively limit parts such as the rack one 74, the gear 75, the rotating rod 76, and the rack two 77.

[0028] As Figure 3As shown, the first clamping block 73 and the second clamping block 78 are slidably connected to the top of the welding table 1. The first toothed rod 74 meshes with the gear 75. Both sides of the rotating rod 76 are rotatably connected to the welding table 1. The gear 75 meshes with the second toothed rod 77. Connecting grooves are formed on both sides of the air storage block 710. A piston air valve 712 is rotatably connected to the inner side of the connecting groove, and a top block 713 is fixedly connected to the inner side of the connecting groove. One side of the telescopic spray pipe 714 away from the air storage block 710 is fixedly connected to the second clamping block 78.

[0029] Through the relative movement of the first clamping block 73 and the second clamping block 78, welding workpieces of different sizes can be effectively fixed. At the same time, when the second clamping block 78 performs the clamping movement, it will drive the piston rod 79 to fill the inside of the air storage block 710 with gas, which is convenient for cleaning the welding slag after welding.

[0030] As Figure 4 As shown, the collection and alarm device 8 includes a collection box 81. A load-bearing plate 82 is slidably connected to the inside of the collection box 81. An elastic telescopic rod 83 is fixedly connected to the bottom of the load-bearing plate 82. An alarm 84 is arranged below the load-bearing plate 82. A handle 85 is fixedly connected to the outer side of the collection box 81. The collection box 81 is slidably connected to the inner wall of the limiting block 2. The collection box 81 is arranged below the welding table 1. The number of the elastic telescopic rods 83 is four, and the alarm 84 is fixedly connected to the lower end inside the collection box 81.

[0031] The welding slag falls from the collection groove into the collection box 81 for collection. After the welding slag in the collection box 81 is collected to a certain weight, the elastic telescopic rod 83 will be squeezed and contracted by the weight of the welding slag. While the elastic telescopic rod 83 contracts and descends, it will drive the load-bearing plate 82 to squeeze the switch of the alarm 84, and the alarm 84 will sound an alarm to notify the staff to handle it, achieving the secondary utilization of the welding slag.

[0032] Working principle: First, place the workpiece to be welded on the top of the welding table 1. Then, turn on the electric cylinder 71. The electric cylinder 71 will drive the electric push rod 72 to move. The electric push rod 72 will push the first clamping block 73 to move. While the first clamping block 73 is moving, it will drive the first toothed rod 74 to mesh with the gear 75. While the gear 75 is meshing and rotating, it will mesh with the second toothed rod 77. After the second toothed rod 77 meshes with the gear 75, it will drive the second clamping block 78 to move. When the second clamping block 78 is moving, it will drive the piston rod 79 to move inside the air storage block 710, and draw in the external gas through the gas check valve 711 into the air storage block 710, filling the inside of the air storage block 710 with gas. At the same time, the second clamping block 78 will move relative to the first clamping block 73 to clamp and fix the workpiece to be welded. After the clamping and fixing are completed, turn on the control module 5. The control module 5 will drive the electric welding torch 6 to perform welding operations on the workpiece. After the welding is completed, the electric cylinder 71 drives the electric push rod 72 and the first clamping block 73 to return to their original positions. While the first clamping block 73 is returning to its original position, it will mesh reversely with the gear 75. The gear 75 will mesh reversely with the second toothed rod 77 to drive the second clamping block 78 to return to its original position. While the second clamping block 78 is returning to its original position, it will drive the piston rod 79 to push the gas stored in the air storage block 710 to spray out from the other side of the telescopic spray pipe 714 to clean the welding slag on the welding table 1. There is no need for manual cleaning, which saves time and effort. The welding slag generated by welding will enter the inside of the collection box 81 through the collection groove. After the welding slag inside the collection box 81 accumulates to a certain weight, the welding slag will squeeze the load-bearing plate 82 and the elastic telescopic rod 83 by its own weight. When the elastic telescopic rod 83 is squeezed, it will contract. While the elastic telescopic rod 83 is contracting, it will drive the load-bearing plate 82 to descend. After the load-bearing plate 82 descends to a fixed position, it will squeeze the switch of the alarm 84, and the alarm 84 will sound an alarm to notify the staff for processing, completing the secondary utilization of the welding slag. After the internal welding slag is processed, the elastic telescopic rod 83 will drive the load-bearing plate 82 to return to its original position, and the switch of the alarm 84 will no longer be squeezed, facilitating continued use next time.

[0033] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
