Description

Technical Field

[0001] The present invention relates to the technical field of welding robots, in particular to an electromagnetic pulse welding robot. Background Art

[0002] Magnesium, aluminum, and their alloys not only offer the advantages of lightweight, but also possess advantages such as high specific strength, excellent thermal and electrical conductivity, and superior electromagnetic shielding and damping properties. Aluminum and its alloys offer advantages such as low density, high specific strength, excellent corrosion resistance, good ductility, and aesthetically pleasing appearance. While both magnesium and aluminum alloys possess excellent individual properties, they often have application requirements that cannot be compromised. For example, magnesium alloy's inherent hexagonal close-packed structure leads to high notch sensitivity and poor room-temperature ductility, limiting its potential advantages. Therefore, combining the two to create magnesium-aluminum alloy composite plates is necessary to fully leverage their respective strengths. Conventional fusion welding to fabricate magnesium-aluminum alloy composite plates inevitably results in the formation of significant amounts of magnesium-aluminum intermetallic compounds, resulting in poor joint performance. Processes such as combined heat sources, resistance spot welding, and cold metal transfer welding cannot truly achieve the goal of improving the composite material's strength. Hot rolling of magnesium-aluminum alloy composite plates also produces brittle intermetallic compounds, impacting overall performance. Friction stir welding is only suitable for processing butt or overlap joints of magnesium-aluminum alloy composite plates. Explosive welding is often performed outdoors, which is dangerous and uncontrollable. Electromagnetic pulse welding, a metalworking technique that uses electromagnetic force to create a solid-state connection by causing metals to collide at high speed, can achieve reliable bonding between aluminum and magnesium alloys.

[0003] However, for the manufacture of larger composite panels, current electromagnetic pulse welding technology has a limited single-pass welding area, insufficient automation for continuous welding, and the concave slope of the panel after the initial weld, which can lead to energy waste and low efficiency when using a single welding coil.

[0028] The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present invention.

[0029] See also Figure 1-10, an electromagnetic pulse welding robot includes a base 1, the upper end of the base 1 is fixedly connected to two groups of first slide rails 2, the upper ends of the two groups of first slide rails 2 are commonly fixedly connected to two groups of second slide rails 3, and a moving component 4 is provided at the front end of the first slide rail 2 near the front end of the base 1. The moving component 4 includes two groups of connecting plates 46, which are slidably connected to the two groups of second slide rails 3 respectively. The two groups of connecting plates 46 are symmetrical to each other, and the opposite sides of the two groups of connecting plates 46 are fixedly connected to a mounting plate 48. A welding component 6 is provided between the two groups of mounting plates 48, and two groups of auxiliary components 5 for driving the movement of the insulating partition are provided between the two groups of first slide rails 2.

[0030] In this embodiment, the moving component 4 includes two groups of first connecting blocks 41 and two groups of second connecting blocks 42. The two groups of first connecting blocks 41 are respectively fixedly connected to the front ends of the two groups of first slide rails 2, and the second connecting blocks 42 are fixedly connected to the upper ends of the second slide rails 3. A first motor 43 is fixedly connected between the first connecting block 41 and the second connecting block 42 on one side of the base 1, and a connecting block is fixedly connected between the first connecting block 41 and the second connecting block 42 on the other side of the base 1. The output end of the first motor 43 is fixedly connected to a first threaded rod 44, and the first threaded rod 44 is rotatably connected to the fixed block. The outer side of the first threaded rod 44 is threadedly connected to an auxiliary block 47, and the auxiliary block 47 is fixedly connected to the connecting plate 46.

[0031] The two groups of first connecting blocks 41 and the two groups of second connecting blocks 42 are fixedly connected with limiting rods 45, the auxiliary blocks 47 are slidably connected with the two groups of limiting rods 45, and the two groups of connecting plates 46 and the two groups of mounting plates 48 are rotatably connected with auxiliary wheels 49 on their opposite sides, and the auxiliary wheels 49 are respectively slidably connected to the upper and lower ends of the second slide rail 3.

[0032] Specifically, the first motor 43 is started to drive the first threaded rod 44 to rotate, so that the auxiliary block 47 moves on the first threaded rod 44 and the limiting rod 45, driving the connecting plate 46 and the mounting plate 48 to move, so that the auxiliary wheel 49 moves on the second slide rail 3, driving the welding assembly 6 to move, and facilitating the welding of the welding assembly 6. The limiting rod 45 can fix the moving path of the auxiliary block 47 to prevent the auxiliary block 47 from rotating with the first threaded rod 44.

[0033] In this embodiment, the welding assembly 6 includes a second motor 61, the output shaft of the second motor 61 is fixedly connected to a connecting shaft 62, the connecting shaft 62 is rotatably connected to the two sets of mounting plates 48, and the outer side of the connecting shaft 62 is fixedly connected to four sets of connecting rods 63. A special-shaped coil 64 is fixedly connected between the two sets of connecting rods 63 near the upper end, and a rectangular coil 65 is fixedly connected between the two sets of connecting rods 63 near the lower end. A cable connector 67 is fixedly connected to the outer side of the connecting rod 63, and a stabilizing assembly 66 is provided on one side of the special-shaped coil 64.

[0034] Specifically, the second motor 61 can drive the connecting shaft 62 to rotate, thereby adjusting the position of the special-shaped coil 64 and the rectangular coil 65, so that the coil is always in contact with the surface of the plate, saving electromagnetic energy and improving the welding effect. The cable connector 67 can facilitate the installation of the cable.

[0035] In this embodiment, the stabilizing component 66 includes a pad 661 fixedly connected to the special-shaped coil 64, and two groups of splints 662 are fixedly connected to one side of the pad 661. The splint 662 is U-shaped, and the inner side of the splint 662 is rotatably connected to a rotating rod 663. The upper end of the rotating rod 663 is slidably connected to a slide 664. The upper end of the slide 664 is fixedly connected to two groups of rotating plates 665. A pressure wheel 666 is rotatably connected between the two groups of rotating plates 665. A clamping plate 669 is fixedly connected to one side of the connecting shaft 62. A clamping plate 669 is provided with a bayonet, which fits in with the rotating rod 663, and the clamping plate 669 is tilted downward.

[0036] Specifically, the pressure wheel 666 will first contact the aluminum alloy and slide on the aluminum alloy plate. As the connecting shaft 62 rotates, the slide 664 drives the rotating rod 663 to deflect on the inner side of the clamping plate 662. At the same time, the rotating rod 663 slides back to the inner side of the slide 664, causing the spring 6612 to contract and be pressed against the aluminum alloy plate through the pressure wheel 666 to prevent the insulating sheet from driving the aluminum alloy plate to move.

[0037] In this embodiment, a rotating shaft 667 is fixedly connected to the inner side of the rotating rod 663, and both ends of the rotating shaft 667 are rotatably connected to the splint 662. Two groups of spring clips 668 are provided on the outer side of the rotating shaft 667. The spring clip 668 is located on the inner side of the splint 662. One end of the spring clip 668 is fixedly connected to the splint 662, and the other end of the spring clip 668 is fixedly connected to the rotating shaft 667.

[0038] Specifically, when the rotating rod 663 rotates inside the clamping plate 662, it drives the rotating shaft 667 to rotate, causing the spring 668 to deflect. The spring 668 then applies force to the rotating rod 663, causing the pressure roller 666 to press the aluminum alloy plate. In this embodiment, the front and rear ends of the slide 664 are each provided with a sliding opening 6611. The front and rear ends of the rotating rod 663 are fixedly connected to a clamping block 6610. The two sets of clamping blocks 6610 are respectively slidably connected to the inside of the two sets of sliding openings 6611. The upper end of the rotating rod 663 is fixedly connected to a spring 6612. The upper end of the spring 6612 is fixedly connected to the upper end of the inner wall of the slide 664.

[0039] Specifically, the block 6610 can be locked through the sliding opening 6611 to facilitate the movement of the rotating rod 663 and fix the moving path of the rotating rod 663.

[0040] In this embodiment, the auxiliary component 5 includes a slider 51 and a third motor 52. The slider 51 and the third motor 52 are respectively slidably connected to the two groups of first slide rails 2. The output shaft of the third motor 52 is fixedly connected to the second threaded rod 53. The outer side of the second threaded rod 53 is threadedly connected to the support block 54. The inner side of the support block 54 is slidably connected to two groups of sliding rods 55. The two ends of the sliding rod 55 are respectively fixedly connected to the slider 51 and the third motor 52. The opposite side of the support block 54 is fixedly connected to a support rod 56, and a stop block 57 is provided at the upper end of the support rod 56.

[0041] Specifically, the positions of the slider 51 and the third motor 52 can be easily adjusted through the first slide rail 2. The two groups of third motors 52 drive the second threaded rod 53 to rotate, so that the support block 54 moves on the second threaded rod 53 and the slide rod 55, and the insulating sheet is driven to move through the support rod 56. The insulating sheet can be purchased through the stop block 57 to prevent the insulating sheet and the support rod 56 from sliding against each other.

[0042] In this embodiment, one side of the special-shaped coil 64 is an arc-shaped surface.

[0043] Specifically, by switching between the special-shaped coil 64 and the rectangular coil 65 , the coil is always in contact with the surface of the plate, thus saving electromagnetic energy and improving the welding effect.

[0044] When in use, the magnesium alloy is placed on the upper end of the base 1, the insulating gasket is placed on the upper ends of the two groups of support rods 56, and the end points of the insulating gasket are aligned with the stop block 57, and then the two groups of third motors 52 are started to drive the second threaded rod 53 to rotate, so that the support block 54 moves on the second threaded rod 53 and the slide rod 55, and the insulating sheet is driven to move to the surface of the magnesium alloy through the support rod 56, and a certain distance is kept between the end of the insulating sheet and the end of the magnesium alloy, and then the aluminum alloy plate is covered on the insulating sheet to align it with the end point of the magnesium alloy, and then the first motor 43 is started to drive the first threaded rod 44 to rotate, so that the auxiliary block 47 moves on the first threaded rod 44 and the limit rod 45, drives the connecting plate 46 and the mounting plate 48 to move, and makes the auxiliary wheel 49 move on the second slide rail 3, drives the welding assembly 6 to move, so that the rectangular coil 65 is aligned with the aluminum alloy end, and then the rectangular coil 65 is energized, and the rectangular coil 65 is used to weld the magnesium alloy to the aluminum alloy. After the first welding with the aluminum alloy, the magnesium alloy and the aluminum alloy are no longer parallel. At this time, the second motor 61 is started to drive the connecting shaft 62 to rotate, so that the special-shaped coil 64 is aligned with the junction of the magnesium alloy and the aluminum alloy. Then, the special-shaped coil 64 is energized to weld the junction of the magnesium-aluminum alloy. Then, the third motor 52 is used to drive the support block 54 to move backward, and the insulating sheet is driven to move through the support rod 56. At the same time, the first motor 43 is used to make the first threaded rod 44 continue to drive the auxiliary block 47 to move, driving the welding assembly 6 to move and continue to weld the magnesium-aluminum alloy until the welding is completed. When the connecting shaft 62 is rotated, the pressure wheel 666 will first contact the aluminum alloy, and as the connecting shaft 62 rotates, the rotating rod 663 is driven to deflect on the inner side of the splint 662 through the slide 664. At the same time, the rotating rod 663 slides back to the inner side of the slide 664, causing the spring 6612 to contract and press the aluminum alloy plate through the pressure wheel 666 to prevent the insulating sheet from driving the aluminum alloy plate to move.

[0045] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
