[0038] As shown in FIG. 1, a wire electrode electroslag welding device includes a support table, a welding torch 2, and a lifting and adjusting mechanism. The lifting and adjusting mechanism includes a linear module 301, a servo motor 302, and a connecting beam 4. The linear module 301 uses a product already available on the market. The servo motor 302 is connected to the linear module 301 to drive the slide table on the linear module 301 to move up and down. One end of the connecting beam 4 is connected to the slide table of the linear module 301. The welding torch 2 is connected to the connecting beam 4, and the end of the welding torch 2 is located above the workpiece to be welded. The linear module 301 is installed on the support table.

[0039] During welding, when it is necessary to adjust the height of the welding torch 2, the servo motor 302 is started, and the slide table on the linear module 301 drives the connecting beam 4 to lift, so that the height of the welding torch 2 can be accurately adjusted as needed, without manual operation, improving the efficiency of height adjustment.

[0040] Further, in one embodiment, a mounting seat 5 is provided on the connecting beam 4, and an X-direction adjusting mechanism 6 is provided on the mounting seat 5. The X-direction adjusting mechanism 6 includes an X-direction connecting frame 601, an X-direction knob 602, an X-direction screw 603, an X-direction screw sleeve 604, an X-direction sliding plate 605, and an X-direction guide rod 606.

[0041] Among them, the X-direction connection frame 601 is fixedly connected to the mounting base 5 and is located above the mounting base 5. The X-direction connection frame 601 is a rectangular parallelepiped frame plate structure with an opening. The X-direction knob 602 is fixedly connected to the X-direction screw rod 603, and the X-direction screw rod 603 passes through a frame plate of the X-direction connection frame 601 and is threadedly connected to the X-direction screw sleeve 604 located inside the X-direction connection frame 601. The X-direction screw rod 603 is rotationally matched with the X-direction connection frame 601. The X-direction sliding plate 605 is fixedly connected to the X-direction screw sleeve 604, and the X-direction guide rod 606 penetrates through the X-direction sliding plate 605, and the two are in a sliding fit relationship. The welding torch 2 is connected to the X-direction sliding plate 605.

[0042] During use, by rotating the X-direction knob 602, the X-direction screw sleeve 604 drives the X-direction sliding plate 605 to move in the X direction perpendicular to the axial direction of the connecting beam 4, so that the front and rear positions of the welding torch 2 relative to the workpiece to be welded can be adjusted. In this way, by setting the X-direction adjustment mechanism 6, the position of the welding torch 2 can be adjusted before welding.

[0043] Furthermore, in an embodiment, in order to more conveniently adjust the position of the welding torch 2 in other directions, a Y-direction adjustment mechanism 7 is also provided. The Y-direction adjustment mechanism 7 is installed on the X-direction sliding plate 605. The Y-direction adjustment mechanism 7 includes a Y-direction connection frame 701, a Y-direction knob 702, a Y-direction screw rod 703, a Y-direction screw sleeve 704, a Y-direction sliding plate 705, and a Y-direction guide rod 706. The welding torch 2 is connected to the Y-direction sliding plate 705.

[0044] Among them, the Y-direction connection frame 701 is fixedly connected to the X-direction sliding plate 605 and is located above the X-direction sliding plate 605. The Y-direction connection frame 701 is also a rectangular parallelepiped frame plate structure with an opening. The Y-direction knob 702 is fixedly connected to the Y-direction screw rod 703, and the Y-direction screw rod 703 passes through a frame plate of the Y-direction connection frame 701 and is threadedly connected to the Y-direction screw sleeve 704 located inside the Y-direction connection frame 701. The Y-direction screw rod 703 is rotationally matched with the Y-direction connection frame 701. The Y-direction sliding plate 705 is fixedly connected to the Y-direction screw sleeve 704, and the Y-direction guide rod 706 penetrates through the Y-direction sliding plate 705, and the two are in a sliding fit relationship. The welding torch 2 is connected to the Y-direction sliding plate 705.

[0045] During use, by rotating the Y-direction knob 702, the Y-direction screw sleeve 704 drives the Y-direction sliding plate 705 to move in the Y direction parallel to the axial direction of the connecting beam 4, so that the left-right position of the welding torch 2 relative to the workpiece to be welded can be adjusted. In this way, by providing the Y-direction adjusting mechanism 7, the position of the welding torch 2 can be adjusted before welding.

[0046] Furthermore, since the current electroslag welding device does not have a welding oscillator and cannot flexibly adapt to different weld widths, to solve this problem, in one embodiment, a wire electroslag swaying mechanism 8 is provided above the Y-direction adjusting mechanism 7. The wire electroslag swaying mechanism 8 is connected to the Y-direction sliding plate 705. The wire electroslag swaying mechanism 8 uses a commercially available product, the manufacturer is Chengdu Huayuan Electric Equipment Co., Ltd., the model is HSBD-1, and its swaying is controlled by a swaying controller (BDK-1). In this embodiment, by adding the wire electroslag swaying mechanism 8, the welding torch 2 can reciprocate in the direction perpendicular to the axial direction of the connecting beam 4 to adjust the position of the welding torch 2 to adapt to the welding conditions of different weld widths.

[0047] Even further, in one embodiment, in order to more accurately adjust the position of the welding torch 2 in the vertical direction, a Z-direction adjusting mechanism 9 is provided on the wire electroslag swaying mechanism 8. The Z-direction adjusting mechanism 9 includes a Z-direction connecting seat 901, a support frame 902, a Z-direction knob 903, a lead screw 904, a Z-direction screw sleeve 905, and an adapter plate 906. The Z-direction connecting seat fixedly connects the sliding member at the upper part of the wire electroslag swaying mechanism 8. The support frame 902 is fixed on the Z-direction connecting seat 901 and placed vertically. The Z-direction knob 903 is fixedly connected to the lead screw 904. The lead screw 904 passes vertically through the support frame 902 and is threadedly connected to the Z-direction screw sleeve 905 sleeved outside. The lead screw 904 is rotationally matched with the support frame 902. The adapter plate 906 is fixedly connected to the Z-direction screw sleeve 905, and the welding torch 2 is connected to the adapter plate 906.

[0048] Preferably, in order to improve the overall structural stability of the Z-direction adjusting mechanism 9, two Z-direction guide rods 907 are fixedly arranged on the support frame 902. The two Z-direction guide rods 907 are parallel to the lead screw 904. Reinforcement blocks 908 are slidably sleeved on the outer parts of the two Z-direction guide rods 907. The lead screw 904 is located between the two Z-direction guide rods 907. The two ends of the adapter plate 906 are fixedly connected to the reinforcement blocks 908 on both sides. The reinforcement blocks 908 and the Z-direction screw sleeve 905 are integrally formed, so that the welding torch 2 can maintain a stable state during the working process.

[0049] By providing the adjusting mechanisms in the X, Y, and Z directions, before welding, in addition to making a large adjustment to the position of the welding torch 2 by using the linear module 301, combined with the precise micro-adjustment in the X, Y, and Z directions, the position of the welding torch 2 can be precisely adjusted to adapt to different welding scenarios. During the entire adjustment process, rotating the knobs in each direction can achieve precise adjustment, with simple operation and low requirements for the operator.

[0050] During the actual welding process, in addition to adjusting the position of the welding torch 2 in the horizontal direction and the height in the vertical direction, the adjustment of the angle of the welding torch 2 is also involved. In order to enable the electro-slag welding device to adjust the angle, in one embodiment, a connecting arm 10 is hinged on the adapter plate 906. By rotating the connecting arm 10, the angle of the welding torch 2 can be adjusted, and the position of the end of the welding torch 2 can be adjusted to perform the angle adjustment in the C-C direction. Further, a connector 11 is fixedly connected to the end of the connecting arm 10. The connector 11 is of an L-shaped structure and has two ends, namely end A and end B. End A of the L-shaped connector 11 is hinged to the fixed plate 14. A connecting seat 28 is provided on the fixed plate 14. The connecting seat 28 is located below the connector 11 and on the same side of the fixed plate 14 as the connector 11. A compression nut 38 is hinged on the connecting seat 28. A transfer rod 29 is hinged on the compression nut 38. The end of the transfer rod 29 far from the connecting seat 28 is fixedly connected to a rotating rod 12. The outer peripheral surface of the rotating rod 12 has a thread. The rotating rod 12 passes through the other end B of the L-shaped connector 11 and is fixedly connected to a rotating disc 13, and the rotating rod 12 and the connector 11 can form a threaded engagement relationship through a nut shaft 39.

[0051] In this embodiment, in order to further achieve fine adjustment of the angle of the welding torch 2, a adapter 11, a connecting seat 28, a connecting rod 29, a rotating rod 12 and a rotating disk 13 are provided in this embodiment. By twisting the rotating disk 13, the adapter 11 moves along the axial direction of the rotating rod 12. At the same time, since there is a spherical hinge relationship between the connecting rod 29 and the connecting seat 28, when the rotating rod 12 rotates, the connecting rod 29 also rotates, and the end A of the adapter 11 connected to the fixed plate 14 also rotates. As a result, the distance between the end B and the connecting seat 28 changes, causing the welding torch 2 to rotate along the E-E direction in the figure, and adjusting the angle and position of the welding torch 2 during the welding process.

[0052] Furthermore, during the welding process, there is also a need to finely adjust the height of the welding torch 2. In order to achieve height fine adjustment during the welding process, in one embodiment, a structure part for height fine adjustment and pressing is provided. Specifically: A driving motor 15 is fixedly provided on one side of the fixed plate 14 close to the adapter 11, and a driving wheel 16 is provided on the other side of the fixed plate 14 far from the adapter 11. The driving motor 15 is connected to the driving wheel 16, driving the driving wheel 16 to rotate. And a pressing wheel 17 is provided on one side of the driving wheel 16. There is a gap between the pressing wheel 17 and the driving wheel 16 for the welding torch 2 to pass through. A pressing wheel shaft 20 is fixedly provided on the fixed plate. A pressing bracket 19 is rotatably provided outside the pressing wheel shaft 20, and the pressing bracket 19 can rotate relative to the fixed plate. The pressing bracket 19 has a large end and a small end. The large end is a frame structure, and the small end is a rod structure. A shaft is provided in the frame of the large end. The pressing wheel is located in the frame structure of the large end and is rotationally matched with the pressing bracket 19 through this shaft, so that the pressing wheel can also rotate. An installation bracket is provided on the fixed plate 14. A pressing handle 21 passes through the installation bracket, and the pressing handle 21 is in a threaded connection with the installation bracket. The pressing handle 21 is located on the side of the large end of the pressing bracket 19. By tightening the pressing handle 21, the large end of the pressing bracket 19 can be pushed towards the driving wheel, thereby reducing the gap between the pressing wheel and the driving wheel and squeezing the welding torch between the two. A spring can also be provided inside the pressing handle 21 to make the pressure between the pressing wheel and the welding torch adjustable. A cam handle 22 is provided on the side of the small end of the pressing bracket 19. The cam handle 22 is rotatably connected to the fixed plate 14 through a cam shaft. Rotating the cam handle 22 can cause the small end of the pressing bracket 19 to rotate due to the fluctuation of the cam structure thereon, so that the large end of the pressing bracket 19 rotates to adjust the gap between the pressing wheel and the driving wheel.

[0053] A support plate 18 is further provided at the bottom of the fixing plate 14, and the welding torch 2 penetrates through the support plate 18. When the height of the welding torch needs to be adjusted, the friction wheel 17 is rotatably engaged with the fixing plate 14, and there is a certain distance between the friction wheel 17 and the driving wheel 16 for the welding torch 2 to pass through. A support plate 18 is further provided at the bottom of the fixing plate 14, and the welding torch 2 penetrates through the support plate 18.

[0054] When the driving motor 15 operates, the driving wheel 16 rotates. Both the driving wheel 16 and the friction wheel pressing wheel 17 have a frictional effect on the welding torch. The rotation of the driving wheel 16 drives the welding torch to move up and down, and the friction wheel pressing wheel 17 also provides friction to ensure the stability of the welding torch 2 during lifting and lowering. The structure is simple and easy to operate.

[0055] At the same time, the pressing handle 21 is used to adjust the pressing of the pressing wheel on the welding torch to ensure the stability of the welding torch. When the welding torch needs to be released, the cam handle 22 is rotated to make the pressing bracket 19 rotate, driving the pressing wheel to move and increasing the distance.

[0056] Furthermore, since the workpiece to be welded has a certain width, the side walls of the workpiece to be welded also need to be well welded. To solve the problem of good welding of the side walls of the workpiece to be welded, the angle of the welding torch needs to be adjusted. Therefore, in this embodiment, a structure part for fine adjustment and pressing of the welding torch angle is provided, specifically: an installation frame 23 is provided on the support plate 18. The installation frame 23 and the driving wheel are located on both sides of the support plate. The installation frame 23 has a hollow cavity inside. An adjustment slider 30 slidably matched with the installation frame 23 is provided in the installation frame 23. One end of the adjustment slider 30 is provided with a groove, and a pressing slider 31 slidably matched with the adjustment slider 30 is provided in the groove. The adjustment handle 32 penetrates through the installation frame 23 from one side and is connected to the internal adjustment slider 30. The adjustment handle 32 is threadedly connected to both the installation frame 23 and the adjustment slider 30. The extrusion handle 33 penetrates through the installation frame 23 from the other side and is connected to the pressing slider 31. The extrusion handle 33 is threadedly connected to both the installation frame 23 and the pressing slider 31. An adjustment wheel shaft 34 rotatably matched with the adjustment slider 30 is provided on the adjustment slider 30. An adjustment rotating wheel 35 is fitted on the adjustment wheel shaft. A pressing wheel shaft 36 rotatably matched with the pressing slider 31 is provided on the pressing slider 31. A pressing wheel 37 is fitted on the pressing wheel shaft 36. The adjustment rotating wheel 35, the pressing wheel 37 and the installation frame 23 are respectively located on both sides of the fixing plate 14. The welding torch can pass through the gap between the adjustment rotating wheel 35 and the pressing wheel 37. Long slot holes 24 are provided on both the fixing plate 14 and the support plate 18 to provide a space for the movement of the adjustment wheel shaft 34, the pressing wheel shaft 36 and the welding torch.

[0057] When the angle of the welding torch needs to be adjusted, rotate the adjustment handle 32, which can drive the adjustment slider 30 to move left and right in the installation frame 23, and then drive the pressing slider 31 to move synchronously, so that the adjustment rotating wheel 35 and the pressing wheel 37 both act and move synchronously. Then the angle of the welding torch can be adjusted, and it moves along the D-D direction in the figure to finely adjust the angle of the welding torch 2. In order to ensure the stability of the welding torch during the angle adjustment process, rotate the extrusion handle 33, which can adjust the position of the pressing slider 31 in the adjustment slider, and drive the pressing wheel 37 to move towards the adjustment rotating wheel, so as to better extrude the welding torch in the middle.
