Description

Technical Field

[0001] The invention relates to the field of steel structure welding, and more particularly to a welding device for steel structure components. Background Art

[0002] Steel is a general term for iron-carbon alloys with a carbon content between 0.02% and 2.11% by mass. Steel is an indispensable part of human production and life due to its high strength, light weight, good overall rigidity and strong resistance to deformation. After processing and production, the steel parts are further processed by welding, bolting or riveting to manufacture the steel structures required for actual production. In the traditional welding process, there may be problems such as incomplete alignment between welds and uneven welding surfaces, which affect the use of the steel structure after welding.

[0003] A Chinese patent with authorization announcement number CN111644797B discloses an automated assembly and welding fixture for steel structures, which clamps steel structures by fixing one end and adjusting the other end. It can clamp and fix steel structures of different lengths. At the same time, through the cooperation between locking bolts, return springs and pressure plates, it can fix steel structures of different thicknesses. The uneven rubber structure on the lower end surface of the pressure plate can both increase the fixing area and reduce the damage to the steel structure caused by clamping and fixing.

[0004] In view of the above problems, existing patents have provided solutions, but most of the welding is done manually, and the welding progress of manual welding is controlled based on experience, which makes it difficult to get started, and it is easy for the welding surface at the weld to be uneven in thickness, affecting the welding quality.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] (1) This solution sets up a welding mechanism so that the transmission member is driven to rotate by a rotating motor, and then the transmission member drives the threaded rod to rotate, and then the welding member is driven to move under the action of the moving block, so that the welding member can evenly weld the steel structure member. The uniform speed movement of the welding member is achieved by the uniform rotation of the rotating motor, thereby improving the quality of welding and avoiding the high labor intensity of manual welding and the problem that the welding movement speed is difficult to control, which affects the welding quality.

[0020] (2) This solution uses the output end of the driving motor to drive the rotating disk to rotate while the welding part moves, so that the adjusting rod inside the rotating disk squeezes the first lifting frame, and then the first lifting frame moves up and down to pull the welding part, so that the welding part rotates reciprocatingly, thereby increasing the width of the weld. The position of the adjusting rod can also be adjusted to adjust the width of the weld, thereby increasing the adaptability of the welding mechanism.

[0021] (3) When facing components with different welding angles, this solution rotates the extrusion plate so that the extrusion plate squeezes the extrusion block, and then the extrusion block no longer contacts the rotating plate. Then, the angle of the weld can be adjusted to meet different welding requirements, further optimizing the adaptability of the welding mechanism.

[0022] (4) This solution provides a moving mechanism and a first support seat and a second support seat so that they can move relative to each other, thereby increasing the ways in which the welded parts can be moved and increasing the moving distance of the welded parts. This avoids the problem that the moving distance of the welded parts on the existing welding mechanism is limited, resulting in the need to adjust the position of the first support seat multiple times.

[0023] (5) In the present solution, when the second support seat is moved, the pulling spring pulls the reciprocating disk, which in turn drives the reciprocating rod to move. The movement of the reciprocating rod drives the moving wheel to move, and the moving wheel supports the second support seat, thereby reducing the friction between the second support seat and the steel structure member, and avoiding the problem of the second support seat being easily offset due to uneven friction when the second support seat moves, thereby affecting the welding accuracy.

[0024] (6) In the present solution, if an offset occurs during the movement of the second support seat and the first support seat, the detection switch will contact the detection plate, and the detection switch will then control the alarm to sound, so that the staff can be reminded in time to adjust the position of the first support seat or the second support seat, thereby avoiding the offset of the second support seat and the first support seat causing the offset of the welded parts, thereby affecting the normal welding of the welded parts.

[0037] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention; it is obvious that the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments, and all other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making creative work are within the scope of protection of the present invention.

[0038] See also Figures 1 to 10 , a welding device for steel structure components, comprising a first support seat 1, the outer surface of the top of the first support seat 1 is rotatably connected to a support rod 2, the outer surface of the top of the support rod 2 is fixedly installed with a fixed shell 3, the interior of the fixed shell 3 is provided with a welding mechanism 4, the welding mechanism 4 is used to weld the spliced ​​steel structure components, and a moving mechanism 5 is provided on one side of the first support seat 1, the moving mechanism 5 is used to extend the welding length of the welding mechanism 4;

[0039] A fixing bolt is provided between the first support seat 1 and the support rod 2, which can be used to position the support rod 2 after rotation. The support rod 2 can be rotated so that the angle of the support rod 2 can be adjusted as needed.

[0040] The welding mechanism 4 includes a first threaded rod 41 that rotates inside the fixed shell 3, and the outer surface of the first threaded rod 41 is threadedly connected to a moving block 42. The outer surfaces of the moving block 42 located on both sides of one end outside the fixed shell 3 are fixedly installed with fixed plates 43, and the inner surfaces of the opposite sides of the two fixed plates 43 are rotatably connected to a rotating block 44 through a rotating rod 410.

[0041] like Figure 2 - Figure 4 As shown, the welding mechanism 4 also includes a rotating plate 45 rotating on the outer surface of both sides of one end of the rotating block 44, and a welding member 46 is fixedly installed on the inner surface of the opposite side of the two rotating plates 45. A rotating motor 47 is fixedly installed on the outer surface of the fixed shell 3 away from the fixed plate 43. A transmission member 48 is provided at the output end of the rotating motor 47, and a wide seam mechanism 49 is fixedly installed on the top of the fixed plate 43.

[0042] In actual use, most steel structure components are welded manually. Manual welding is labor-intensive and cannot guarantee the uniformity of the weld during long-term welding, which affects the aesthetics and quality of the welding.

[0043] Before welding, first complete the assembly of the steel structure components and fix the assembled components, then place the first support seat 1 on one side of the assembled components to be welded, and then position the placed first support seat 1 through the positioning piece. After positioning, rotate the fixed shell 3 so that the fixed shell 3 remains parallel to the components on one side, and then complete the preparation of the welding part 46.

[0044] After the preparation is completed, by controlling the rotation of the output end of the rotating motor 47, the rotation of the output end of the rotating motor 47 will drive the first threaded rod 41 to rotate through the transmission member 48, and the rotation of the first threaded rod 41 will cause the moving block 42 to move, and the movement of the moving block 42 will drive the fixed plate 43, the rotating block 44 and the welding member 46 to move, and then the welding of the steel structure components can be completed through the welding member 46, avoiding the problem that the welding speed cannot be controlled during the existing manual welding, resulting in uneven welding thickness and affecting the welding quality.

[0045] like Figure 5 and Figure 6 As shown, the wide gap mechanism 49 includes a connecting plate 491 fixed to the top surface of the fixed plate 43, a driving motor 492 is fixedly installed on the inner surface of the connecting plate 491, a rotating disk 493 is fixedly installed on the output end of the driving motor 492, an adjusting slot 494 is provided inside the rotating disk 493, and a second threaded rod 495 is rotatably connected inside the rotating disk 493, and an adjusting rod 496 is threadedly connected to the outer surface of the second threaded rod 495 located inside the adjusting slot 494, a mounting frame 497 is fixedly installed on the outer surface of one side of the fixed plate 43, a lifting plate 498 is slidably connected inside the mounting frame 497, a first lifting frame 4910 is fixedly installed on the top of the lifting plate 498, a second lifting frame 4911 is fixedly installed on the outer surface of the rotating rod 410 close to one end of the first lifting frame 4910, a transmission rod 4912 is fixedly installed on the outer surface of one side of the lifting plate 498 close to the second lifting frame 4911, and a stabilizing mechanism 499 is provided inside the rotating block 44.

[0046] like Figure 5 and Figure 6 As shown, one end of the transmission rod 4912 is located inside the second lifting frame 4911, and the outer surface of the transmission rod 4912 is slidably connected to the inner surface of the second lifting frame 4911, one end of the adjusting rod 496 is located inside the first lifting frame 4910, and the surface of the adjusting rod 496 is movably connected to the inner surface of the first lifting frame 4910, the surface of the rotating rod 410 is fixedly connected to the rotating block 44, the transmission member 48 includes a pulley and a transmission belt, and the transmission member 48 is used to drive the first threaded rod 41 to rotate synchronously when the output end of the rotating motor 47 rotates.

[0047] In actual use, due to factors such as the thickness and length of the components, different weld widths are required. Based on this, by setting the wide seam mechanism 49, while welding is being performed, the output end of the drive motor 492 is controlled by the control switch to rotate, and the rotation of the output end of the drive motor 492 will drive the rotating disk 493 to rotate, and the rotation of the rotating disk 493 will drive the adjusting rod 496 to rotate, and then the rotating adjusting rod 496 squeezes the first lifting frame 4910, so that the first lifting frame 4910 drives the lifting plate 498 to move upward, and the lifting plate 498 moves upward to drive the transmission rod 4912 to move upward, and then the transmission rod 4912 drives the second lifting frame 4911 to swing up and down reciprocatingly, and the swinging of the second lifting frame 4911 drives the rotating block 44 to reciprocate, and then drives the welding piece 46 to reciprocate, so as to increase the width of the weld, and the second threaded rod 495 can be rotated to adjust the position of the adjusting rod 496, and then the angle of the second lifting frame 4911 to rotate up and down is adjusted, so as to achieve the purpose of adjusting the width of the weld.

[0048] like Figure 7 and Figure 8 As shown, the stabilizing mechanism 499 includes an extrusion groove 4991 opened inside the rotating block 44, an extrusion block 4992 is slidably connected inside the extrusion groove 4991, an extrusion spring 4993 is fixedly installed on one end of the extrusion block 4992 located inside the extrusion groove 4991, a support frame 4994 is fixedly installed on the surface of the rotating block 44 and on one side of the extrusion groove 4991, an extrusion disk 4995 is rotatably connected inside the support frame 4994, and a rubber block is fixedly installed on one side of the extrusion block 4992 close to the rotating plate 45.

[0049] During actual use, when welding steel structures, the angles of the welding components are different, which leads to the need to rotate the welding component 46 according to the welding angle of the components. Based on this, by setting up a stabilizing mechanism 499, when the angle of the welding component 46 needs to be adjusted, the extrusion disk 4995 is rotated. The rotation of the extrusion disk 4995 will cause the extrusion disk 4995 to squeeze the extrusion block 4992, and then the extrusion block 4992 will no longer contact with one end of the rotating plate 45, so that the angle of the welding component 46 can be adjusted. After the adjustment is completed, the extrusion disk 4995 is rotated and reset again, so that the extrusion disk 4995 no longer squeezes the extrusion block 4992, and the extrusion spring 4993 pushes the extrusion block 4992 to be in close contact with the rotating plate 45, so as to achieve the positioning of the welding component 46 after rotation, thereby increasing the adaptability of the welding component 46.

[0050] like Figure 2As shown, the moving mechanism 5 includes a second support seat 51 arranged on one side of the first support seat 1, a first shrinking shell 52 is fixedly installed on one side of the top of the second support seat 51, and a third threaded rod 53 is threadedly connected to the top of the first shrinking shell 52, a second shrinking shell 54 is fixedly installed on the top of the first support seat 1 and located on one side of the first shrinking shell 52, a rotating motor 55 is fixedly installed on the side of the second shrinking shell 54 away from the first shrinking shell 52, a first electromagnet 56 is fixedly installed on the bottom of the first support seat 1, a second electromagnet 57 is fixedly installed on the bottom of the second support seat 51, and a rolling mechanism 58 is provided on the bottom of the first support seat 1 and the second support seat 51.

[0051] In actual use, since the length of the first threaded rod 41 is limited, which leads to a limited moving distance of the moving block 42. Therefore, when welding a component with a longer length, it is necessary to repeatedly move the position of the first support seat 1. Based on this, through the setting of the moving mechanism 5, before the welding starts, firstly, by controlling the second electromagnet 57 coil under the second support seat 51 to generate a magnetic field, the second electromagnet 57 and the component are attracted to each other, and then the welding work can start. When the welding work needs to move the welding piece 46, the output end of the rotating motor 55 is controlled by the control switch to rotate. The rotation of the output end of the rotating motor 55 will drive the third threaded rod 53 to rotate. The rotation of the third threaded rod 53 will cause the third threaded rod 53 to move. The movement of the third threaded rod 53 will drive the rotating motor 55 to move. The movement of the machine 55 will drive the second shrinking shell 54 to move, and then the second shrinking shell 54 will drive the first support seat 1 to move in the direction of the second support seat 51. When the first support seat 1 contacts the second support seat 51, the rotating motor 55 is controlled to stop rotating, and the rotating motor 47 drives the transmission member 48 to rotate. At this time, the first threaded rod 41 continues to drive the welding member 46 to complete the mobile welding, and the second electromagnet 57 is closed by the control switch, and the first electromagnet 56 is opened to fix the first support seat 1, and then the output end of the rotating motor 55 is controlled to rotate in the opposite direction. Under the action of the third threaded rod 53, the first support seat 1 and the second support seat 51 can be driven to move away from each other, and then the above operation is repeated, so that the moving first support seat 1 completes the movement of the welding member 46, thereby increasing the welding length of the component.

[0052] In the above process, the movement of the welding part 46 mainly adopts the movement when the second support seat 51 pulls the first support seat 1, and the rotation of the first threaded rod 41 is mainly the transition when the second support seat 51 moves, which is as follows: There are two ways to move the welding part 46, and the two methods can only be used separately. One is that the rotating motor 47 drives the first threaded rod 41 to move the welding part 46, and the other is that when the rotating motor 55 drives the third threaded rod 53 to rotate, the first support seat 1 moves toward the direction of the second support seat 51 and will drive the welding part 46 to move. When the rotating motor 47 rotates, the rotating motor 55 stops rotating, and the rotating motor 55 rotates to drive the third threaded rod 53 to push the second support seat 51, so that the first support seat 1 and the second support seat 51 move away from each other. The rotation speed of the rotating motor 55 is relatively fast, so that the movement of the second support seat 51 can be completed quickly, which is convenient for quickly pulling the first support seat 1 after moving, so as to further increase the welding length.

[0053] like Fig. 9 As shown, the rolling mechanism 58 includes a first mounting plate 581 fixed to the outer surface of the first support seat 1, and the first mounting plate 581 is internally slidably connected with a reciprocating rod 582, the top of the reciprocating rod 582 is fixedly mounted with a reciprocating disk 583, and the bottom of the reciprocating rod 582 is fixedly mounted with a moving wheel 584, the outer surface of the reciprocating rod 582 is sleeved with a pulling spring 585, and a detection mechanism 586 is fixedly mounted on one side of the top of the first support seat 1 and the second support seat 51.

[0054] like Fig. 9 As shown, the third threaded rod 53 is rotatably connected to the second contraction shell 54, the output end of the rotating motor 55 is fixedly connected to one end of the third threaded rod 53, and the two ends of the pulling spring 585 are respectively fixedly connected to the surface of the reciprocating disk 583 and the surface of the first mounting plate 581, and a total of four first mounting plates 581 are arranged, and the four first mounting plates 581 are evenly distributed around the first support seat 1.

[0055] In actual use, since the first support seat 1 and the second support seat 51 need to be moved repeatedly, and the second support seat 51 is in direct contact with the component, the friction force or driving force generated is uneven, which makes it easy for the second support seat 51 to shift. Based on this, by setting a rolling mechanism 58, when the second support seat 51 needs to be moved, the second electromagnet 57 is first turned off by the control switch, so that the second electromagnet 57 no longer generates adsorption force with the component, and then the pulling spring 585 pulls the reciprocating disk 583, so that the reciprocating disk 583 drives the reciprocating rod 582 to move downward, so that the reciprocating rod 582 drives the moving wheel 584 to support the second support seat 51, so that the second support seat 51 is no longer in contact with the component, and then when the second support seat 51 is moved, the friction between the second support seat 51 and the component can be greatly reduced, thereby avoiding the problem of the second support seat 51 shifting due to uneven friction.

[0056] like Fig.10 As shown, the detection mechanism 586 includes a fixed cylinder 5861 fixed to the outer surface of the first support seat 1, and the fixed cylinder 5861 is slidably connected to the inside of the detection rod 5862, and the first spring 5863 is fixedly installed on one end of the detection rod 5862 located inside the fixed cylinder 5861, and a detection disk 5864 is fixedly installed on the outer surface of the middle part of the detection rod 5862, and detection switches 5865 are fixedly installed on both sides of the fixed cylinder 5861 and the detection disk 5864.

[0057] like Fig.10 As shown, the detection disk 5864 is located in the middle of the two detection switches 5865, and the detection disk 5864 does not contact the two detection switches 5865, one end of the detection rod 5862 is located outside the fixed cylinder 5861, one end of the first spring 5863 is fixedly connected to the inner surface of the fixed cylinder 5861, and the outer surface of the detection disk 5864 does not contact the inner surface of the fixed cylinder 5861.

[0058] In actual use, when the second support seat 51 is offset due to vibration or the electromagnet is not turned on in time, it is impossible to judge whether it is offset by observation alone, which affects the welding accuracy. Based on this, by setting the detection mechanism 586, when the second support seat 51 or the first support seat 1 is offset in the direction of the component, the detection rod 5862 will be squeezed, and then the detection rod 5862 will drive the detection disk 5864 to move, so that the reciprocating disk 583 moves, which will make the reciprocating disk 583 contact with the detection switch 5865, so that the detection switch 5865 controls the alarm to sound an alarm, and when the second support seat 51 or the first support seat 1 is offset in the direction away from the component, the reciprocating rod 582 will be unrestricted, and then the first spring 5863 will push the detection rod 5862, so that the detection rod 5862 drives the detection disk 5864 to contact with the detection switch 5865, and then the detection switch 5865 controls the alarm to sound, thereby reminding the staff that the welding mechanism 4 is offset, so that timely adjustments can be made to ensure the welding accuracy.

[0059] Instructions for use: When in use, first place the first support seat 1 and the second support seat 51 on the surface of the spliced ​​steel structure member, and make the first support seat 1 and the second support seat 51 on one side of the seam to be welded, and then the second electromagnet 57 completes the positioning of the second support seat 51. After positioning, the welding part 46 is controlled to run, and the output end of the rotating motor 55 drives the third threaded rod 53 to rotate. Under the action of the third threaded rod 53, the first support seat 1 moves toward the direction of the second support seat 51, and the welding part 46 is driven to move during the movement, and then the welding part 46 welds the steel structure. At the same time, the driving motor 492 drives the rotating disk 493 to rotate, so that under the action of the rotating disk 493, the welding part 46 reciprocates up and down, so that the width of the weld can be increased, and the second threaded rod 495 can also be rotated. The rotation of the second threaded rod 495 will move the adjusting rod 496, and then adjust the position of the adjusting rod 496. The purpose of adjusting the weld width is achieved, and when moving, the second support seat 51 is detected through the detection switches 5865 on both sides of the detection plate 5864, so that when an offset occurs, the detection plate 5864 will contact the detection switch 5865, and the detection switch 5865 will control the alarm to sound, reminding the staff to make timely adjustments.
