Description

Technical Field

[0001] The present invention belongs to the technical field of aluminum alloy sheet processing, and particularly relates to a welding system for aluminum alloy sheets. Background Art

[0002] Aluminum alloy is one of the most widely used non-ferrous metal structural materials in industry and has been widely used in aviation, aerospace, automotive, machinery manufacturing, shipbuilding, and chemical industries. With the rapid development of the industrial economy, the demand for aluminum alloy welded structural parts is increasing day by day, and the research on the weldability of aluminum alloy has also been deepened accordingly.

[0003] Currently, when welding aluminum alloy sheets, in order to improve the welding effect, laser welding is generally used. During the laser welding process of two aluminum alloy plates, in order to avoid the high temperature at the welding site during welding, which may cause deformation of the aluminum alloy plates, air cooling is generally used to cool the welding site. However, the existing air cooling devices are fixed and cannot move along with the welding direction, and the air cooling direction is single, which affects the cooling effect on the welding site and thus the quality after welding. Therefore, we provide a welding system for aluminum alloy sheets to solve the above problems. Summary of the Invention

During the welding process of the butt joints of two aluminum alloy sheets by a laser welding device, two air ducts are enabled to move synchronously with the laser welding device, so that the air generated by the rotation of the two air ducts can quickly cool the welding site. And by the reverse rotation of the two air ducts, the phenomenon of uneven heat dissipation on both sides of the aluminum alloy sheets caused by unidirectional heat dissipation, which may lead to deformation of the aluminum alloy sheets after welding, is avoided. At the same time, the air generated by the two air ducts has a cleaning effect on the dropped welding slag generated during welding, thereby effectively improving the quality of the aluminum alloy sheets after welding, and solving the problems that when welding existing aluminum alloy sheets, in order to improve the welding effect, laser welding is generally used.

[0033] Example 1, please refer to Figure 1-13, the present invention provides the following technical solutions: A welding system for aluminum alloy plates, including a positioning component 1; the positioning component 1 includes a base 101, a U-shaped frame 102 is fixedly connected to the top of the base 101, and a laser welding component 2 is rotatably fitted on the U-shaped frame 102. The laser welding component 2 includes a lead screw 201 rotatably connected to opposite side surfaces of the U-shaped frame 102. A first slider 202 threadedly connected to the circumferential surface of the lead screw 201 and slidably connected to the inner top of the U-shaped frame 102 is provided below the first slider 202 with a laser welding device 203; an air-cooling component 3 is threadedly fitted on the circumferential surface of the lead screw 201. The air-cooling component 3 includes a second slider 301 threadedly connected to the circumferential surface of the lead screw 201 and slidably fitted to the inner top of the U-shaped frame 102. A first electric push rod 302 is fixedly connected to the bottom of the second slider 301. A first U-shaped plate 303 is fixedly connected to the output end of the first electric push rod 302. A second U-shaped plate 304 is fixedly connected to the bottom of the first U-shaped plate 303. A U-shaped support plate 305 is fixedly connected to opposite side surfaces of the second slider 301; a cylindrical tube 306 is rotatably connected through the bottom of the U-shaped support plate 305. A first rotating shaft 307 passing through the second U-shaped plate 304 is slidably connected to the inner circumferential surface of the cylindrical tube 306. A first bevel gear 308 is rotatably connected to the bottom of the first rotating shaft 307. Second rotating shafts 309 are rotatably connected to opposite inner side surfaces of the second U-shaped plate 304. Second bevel gears 310 meshing with the first bevel gear 308 are fixedly connected to opposite end portions of the two second rotating shafts 309. Air ducts 311 are fixedly connected to the circumferential surfaces of the two second rotating shafts 309. A plurality of through holes are uniformly formed through the outer wall of the air duct 311, and a blower is installed inside the air duct 311.

[0034] The operation process of this embodiment is as follows: (as shown in Figure 2 , 8 , 9) After clamping and aligning two aluminum alloy plates through the positioning component 1, control the rotation of the lead screw 201 to drive the first slider 202 to move from the left side to the right side by the lead screw 201, and then drive the laser welding device 203 to move from the left side to the right side through the first slider 202, so as to realize the welding of the butt joint of the two aluminum alloy plates by the laser welding device 203;

[0035] First, the first electric push rod 302 is controlled to drive the first U-shaped plate 303 to move downward, and then the second U-shaped plate 304 is moved downward, so that the second U-shaped plate 304 synchronously drives the first rotating shaft 307 and the two air ducts 311 to move downward, so that the two air ducts 311 are moved close to the weld, and the screw rod 201 is synchronously rotated to drive the second slider 301 to move from the left to the right, so that the second slider 301 moves from the left to the right through the first electric push rod 302, the first U-shaped plate 303, the second U-shaped plate 304 and the two air ducts 311. During the movement of the two air ducts 311, the cylindrical tube 306 is synchronously controlled to rotate through the rotation of the screw rod 201, and the cylindrical tube 306 drives the first rotating shaft 307 to rotate, and then drives the first bevel gear 308 to rotate, so that the first bevel gear 308 synchronously meshes and drives the two second bevel gears 310 to rotate, so that the two second bevel gears 308 respectively drive the two second rotating shafts 309 to rotate, and then drive the two air ducts 311 to rotate. At the same time, the rotation directions of the two air ducts 311 are opposite. In the process of welding the two aluminum alloy plates at the butt joint by the laser welding equipment 203, the two air ducts 311 follow the laser welding equipment 203 to move synchronously, so that the wind generated by the rotation of the two air ducts 311 can quickly cool down the welding point, and the two air ducts 311 rotate in opposite directions to avoid the phenomenon of uneven heat dissipation of the aluminum alloy plates on both sides caused by one-way heat dissipation, resulting in deformation of the aluminum alloy plates after welding. At the same time, the wind generated by the two air ducts 311 has a cleaning effect on the detached welding slag generated by welding, thereby effectively improving the quality of the aluminum alloy plates after welding.

[0036] For example 2, please refer to Figure 1-13 The second embodiment is improved on the basis of the first embodiment as follows: the positioning assembly 1 also includes a control box 103 fixedly connected to the top of the base 101, and two groups of clamping members 4 are symmetrically slidably connected to the top of the base 101; the clamping members 4 include two moving plates 401 slidably connected to the top of the base 101, and a moving rod 402 is slidably connected to one side of the moving plate 401, and an L-shaped clamping plate 403 is fixedly connected to one end of the moving rod 402, and a baffle 404 is fixedly connected to the other end of the moving rod 402, and a first spring 405 mounted on the moving rod 402 is fixedly connected between the moving plate 401 and the L-shaped clamping plate 403.

A pressing plate 116 which is slidably sleeved on the threaded rod 107 is fixedly connected between adjacent two first sliding rods 113.

[0038] The operation process of this embodiment is as follows: First, energize the four electromagnets 105 to make the electromagnets 105 generate suction force, thereby driving the baffle 404 to move towards the adjacent electromagnet 105, and then driving the L-shaped clamping plate 403 to move towards the adjacent electromagnet 105 through the moving rod 402, so that the adjacent two L-shaped clamping plates 403 expand outwards (at this time, the first spring 405 is compressed). Then, place the two aluminum alloy plates correspondingly between the adjacent two L-shaped clamping plates 403. Subsequently, cut off the power supply of the electromagnet 105. Under the elastic force of the first spring 405, drive the L-shaped clamping plate 403 to move towards the aluminum alloy plate, thereby completing the clamping of the aluminum alloy plate. Then, control the double-headed motor 106 to drive the two threaded rods 107 to rotate, so that the threaded rods 107 drive the irregular-shaped plate 108 to move towards the L-shaped clamping plate 403, and further drive the push plate 109 to move towards the L-shaped clamping plate 403, so that the two push plates 109 push the two aluminum alloy plates to move towards each other, so that the two aluminum alloy plates are attached together, completing the alignment of the two aluminum alloy plates, and further realizing the rapid positioning of the two aluminum alloy plates, thereby improving the production efficiency.
