Description

Technical Field

[0001] This utility model relates to the field of composite metal sheet processing technology, and in particular to an electromagnetic assisted welding workbench for composite metal sheets. Background Technology

[0002] Fusion welding is a type of welding method. It involves heating the workpiece to locally melt it and form a molten pool. After the molten pool cools and solidifies, a connection is formed between the materials. However, when fusion welding is used to weld thicker composite metal plates, the molten pool cannot maintain a dynamic balance under the combined action of its own gravity, surface tension, and metal vapor pressure. This can easily lead to defects such as weld surface collapse, bottom hump, or even dripping from the root of the molten pool, making it difficult to form a weld.

[0003] The existing technology typically addresses the above situation by installing a current module and a magnetic field module inside the welding workbench used to place the composite metal sheet. When the current module applies current to the molten metal at the weld pool, the magnetic field module applies a magnetic field at the weld pool, causing the energized molten metal to be subjected to electromagnetic force in the magnetic field, thus supporting the molten metal. This allows the molten metal to maintain dynamic equilibrium under the combined action of its own gravity, surface tension, metal vapor pressure, and electromagnetic force, thereby ensuring welding quality.

[0004] However, since both the current module and the magnetic field module are located inside the welding workbench, the operating space is relatively small due to the obstruction of the welding workbench shell during the regular maintenance of various components, especially the magnet adjustment seat. This makes maintenance difficult and time-consuming, and inconvenient in actual use.

[0005] Therefore, it is necessary to invent an electromagnetically assisted welding workbench for composite metal sheets to solve the above problems. Utility Model Content

[0006] The purpose of this utility model is to provide an electromagnetic assisted welding workbench for composite metal sheets, which can facilitate the periodic maintenance of the drive module, current module, and magnetic field module, avoiding obstruction caused by the housing, reducing maintenance difficulty, shortening maintenance time, and making it more convenient in actual use. This solves the problem mentioned in the background art that, because the current module and magnetic field module are both located inside the welding workbench, the operating space is relatively small due to the obstruction of the welding workbench shell, resulting in greater maintenance difficulty, longer maintenance time, and inconvenience in actual use.

[0007] According to one aspect of this disclosure, the following technical solution is provided: an electromagnetic assisted welding workbench for composite metal sheets, comprising:

[0008] A support mechanism is provided for housing the drive module, the current module, and the magnetic field module.

[0009] The flip-support mechanism includes a movable plate that is movably connected to the top left side of the housing via a hinge. A rotating shaft is rotatably provided on the inner side of the movable plate via a bearing. A flip plate is fixedly connected to the right end of the rotating shaft. Multiple clearance channels are provided on the top of the flip plate, and an operating handle is fixedly provided on the right end of the flip plate.

[0010] A drive module, which is used to drive the current module and the magnetic field module to move along the avoidance channel;

[0011] Two sets of current modules, used to apply current to the molten metal at the weld pool; and

[0012] Two sets of magnetic field modules are used to apply a magnetic field to the weld pool.

[0013] An electromagnetic assisted welding workbench for composite metal sheets according to at least one embodiment of the present disclosure, wherein the support mechanism includes a housing, a clearance groove is provided on the top left side of the housing, and a wiring channel is provided on the top right side of the housing.

[0014] According to at least one embodiment of the present disclosure, an electromagnetic assisted welding workbench for composite metal sheets is provided, wherein a support base is fixedly provided at the bottom of the housing, and universal wheels are fixedly provided at the four corners of the bottom of the support base, and locking wrenches are provided on the universal wheels.

[0015] According to at least one embodiment of the present disclosure, an electromagnetic assisted welding workbench for composite metal sheets includes a drive module comprising a U-shaped frame fixedly disposed at the bottom of a flip plate, an electric slide rail fixedly disposed on the inner side of the U-shaped frame, an electric slider sleeved on the outer side of the electric slide rail, and a base plate fixedly disposed on the right side of the electric slider.

[0016] According to at least one embodiment of the electromagnetic assisted welding workbench for composite metal sheets of the present disclosure, any group of the current modules includes an insulating bracket fixedly disposed on the top of the base plate, an electric brush slidably disposed on the inner side of the insulating bracket in the vertical direction, an insulating partition fixedly disposed at the bottom end of the electric brush, and an elastic support member fixedly connected to the bottom of the insulating partition.

[0017] According to at least one embodiment of the present disclosure, an electromagnetically assisted welding workbench for composite metal sheets includes one of the brushes connected to the positive terminal of a current generator via a wire, and the other brush connected to the negative terminal of the current generator via a wire.

[0018] According to at least one embodiment of the electromagnetic assisted welding workbench for composite metal sheets of the present disclosure, any group of magnetic field modules includes a magnet adjustment seat fixedly disposed on the top of the base plate, and a permanent magnet is fixedly disposed on the top of the magnet adjustment seat.

[0019] The technical effects and advantages of this utility model are as follows:

[0020] This invention features a flipping support mechanism. When inspecting the drive module, current module, and magnetic field module, the flipping plate and rotating shaft are lifted using the operating handle. This allows the movable plate to rotate around the hinge. The operating handle then drives the flipping plate to rotate around its axis until the drive module, current module, and magnetic field module, located at the bottom of the flipping plate, are rotated to the top. The flipping plate is then lowered using the operating handle, resting on top of the housing and supported. At this point, the drive module, current module, and magnetic field module are all exposed and unobstructed. Compared to existing technologies, this invention allows for more convenient periodic inspections of the drive module, current module, and magnetic field module, avoiding obstruction caused by the housing, reducing inspection difficulty, shortening inspection time, and making it more convenient in actual use.

[0033] For descriptive purposes, this disclosure may use spatial relative terms such as “below,” “under,” “below,” “down,” “above,” “above,” “higher,” and “side (e.g., in a “sidewall”)” to describe the relationship between one component and another component as shown in the accompanying drawings. In addition to the orientations depicted in the drawings, the spatial relative terms are also intended to encompass different orientations of the device during use, operation, and / or manufacture. For example, if the device in the drawings is flipped, a component described as “below” or “under” other components or features would subsequently be positioned “above” said other components or features. Thus, the exemplary term “below” can encompass both “above” and “below” orientations. Furthermore, the device may be otherwise positioned (e.g., rotated 90 degrees or in other orientations), thus interpreting the spatial relative descriptive terms used herein accordingly.

[0035] Figure 2 This is a schematic diagram of the support mechanism 1 for an electromagnetic assisted welding workbench of composite metal sheet according to one embodiment of the present disclosure.

[0036] Figure 3 This is a schematic diagram of the flipping support mechanism 2 of an electromagnetic assisted welding workbench for composite metal sheets according to one embodiment of the present disclosure.

[0037] Figure 4 This is a schematic diagram of the drive module 3 of an electromagnetic assisted welding worktable for composite metal sheets according to one embodiment of the present disclosure.

[0038] Figure 5 This is a schematic diagram of the current module 4 and magnetic field module 5 of an electromagnetic assisted welding workbench for composite metal sheets according to one embodiment of the present disclosure.

[0039] like Figures 1-5 As shown, the electromagnetic assisted welding worktable for composite metal sheets disclosed herein may include: a support mechanism 1, a flipping support mechanism 2, a drive module 3, two sets of symmetrically arranged current modules 4, and two sets of symmetrically arranged magnetic field modules 5, etc.

[0040] like Figure 2 As shown in this disclosure, the support mechanism 1 includes a housing 11, an clearance groove 12 is provided on the top left side of the housing 11, a wiring channel 13 is provided on the top right side of the housing 11, and a support base 14 is fixedly provided at the bottom of the housing 11. Universal wheels 15 are fixedly provided at the four corners of the bottom of the support base 14, and locking levers are provided on the universal wheels 15.

[0041] This allows for the laying of wires using the wiring channel 13, and the movement of the entire device using the casters 15. After moving to the area below the laser welding head, the casters 15 can be locked using a locking wrench to prevent the device from moving arbitrarily during the welding process.

[0042] like Figure 3 As shown, in a preferred embodiment, the flipping support mechanism 2 includes a movable plate 21 connected to the top left side of the housing 11 via a hinge. A rotating shaft 22 is rotatably provided on the inner side of the movable plate 21 via a bearing. A flipping plate 23 is fixedly connected to the right end of the rotating shaft 22. Multiple clearance channels 24 are provided on the top of the flipping plate 23, and an operating handle 25 is fixedly provided on the right end of the flipping plate 23.

[0043] Therefore, when inspecting the drive module 3, current module 4, and magnetic field module 5, the operating handle 25 is used to lift the flip plate 23 and the rotating shaft 22, causing the movable plate 21 to rotate around the hinge. Then, the operating handle 25 drives the flip plate 23 to rotate around the flip plate 23 until the drive module 3, current module 4, and magnetic field module 5 located at the bottom of the flip plate 23 are rotated to the top of the flip plate 23. Then, the operating handle 25 is used to lower the flip plate 23, so that the flip plate 23 is supported on the top of the housing 11 after flipping. At this time, the drive module 3, current module 4, and magnetic field module 5 are all in an unobstructed exposed state. Compared with the prior art, it is more convenient to perform regular inspections of the drive module 3, current module 4, and magnetic field module 5, avoiding obstruction caused by the housing 11, reducing the difficulty of inspection, shortening the inspection time, and making it more convenient in actual use.

[0044] In addition, the multiple clearance channels 24 will not obstruct the movement of the brush 42 and the permanent magnet 52, ensuring that the brush 42 and the permanent magnet 52 can move along the direction of the weld pool.

[0045] like Figure 4 As shown in this disclosure, the drive module 3 includes a U-shaped frame 31 fixedly disposed at the bottom of the flip plate 23, an electric slide rail 32 fixedly disposed on the inner side of the U-shaped frame 31, an electric slider 33 being driven and sleeved on the outer side of the electric slide rail 32, and a base plate 34 fixedly disposed on the right side of the electric slider 33.

[0046] Therefore, the electric slide rail 32 can drive the electric slider 33 to move, and the electric slider 33 can drive the current module 4 and the magnetic field module 5 to move through the base plate 34, so that the current module 4 and the magnetic field module 5 are always below the weld pool.

[0047] like Figure 5 As shown, in a preferred embodiment, any set of current modules 4 includes an insulating bracket 41 fixedly mounted on the top of the base plate 34. A brush 42 is slidably mounted on the inner side of the insulating bracket 41 in the vertical direction. An insulating partition 43 is fixedly mounted on the bottom of the brush 42. An elastic support member 44 is fixedly connected to the bottom of the insulating partition 43. The elastic support member 44 is a spring. One brush 42 is connected to the positive terminal of the current generator through a wire, and the other brush 42 is connected to the negative terminal of the current generator through a wire. Any set of magnetic field modules 5 includes a magnet adjustment seat 51 fixedly mounted on the top of the base plate 34. A permanent magnet 52 is fixedly mounted on the top of the magnet adjustment seat 51.

[0048] This allows the two composite metal plates to be placed on top of the flip plate 23, with the welding position located at the top of the central clearance channel 24. Subsequently, the laser welding head forms a weld pool on the weld bead of the two composite metal plates. The current module 4 applies current to the molten metal at the weld pool, and the magnetic field module 5 applies a magnetic field to the weld pool, so that the energized molten metal is subjected to electromagnetic force in the magnetic field to support the molten metal. This allows the molten metal to maintain dynamic equilibrium under the combined action of its own gravity, surface tension, metal vapor pressure, and electromagnetic force.

[0049] It should also be noted that the current module 4 and the magnetic field module 5 are both solutions already disclosed in the prior art and are not essential technical features for solving the technical problem of this application. Therefore, this application will not elaborate on the specific principles here.

[0050] It should also be noted that any content not described in detail in this specification is prior art known to those skilled in the art.

[0051] Those skilled in the art should understand that the above embodiments are merely for illustrating the present disclosure and are not intended to limit the scope of the disclosure. Those skilled in the art can make other changes or modifications based on the above disclosure, and these changes or modifications still fall within the scope of the present disclosure.
