Description

Technical Field

[0001] This application relates to the field of steel structure welding technology, and in particular to a positioning device and positioning method for steel structure I-beams. Background Technology

[0002] Steel structures are structures composed of steel materials and are one of the main types of building structures. They are widely used in building construction and road construction, shortening construction time and reducing project complexity. H-beams are an economical and efficient profile with a more optimized cross-sectional area distribution and a more reasonable strength-to-weight ratio. Because all parts of an H-beam are arranged at right angles, it has advantages such as strong bending resistance in all directions, simple construction, cost savings, and lightweight structure.

[0003] Traditionally, H-beams are mostly cut manually. A processing platform is set up on the construction site, and the cut raw materials are assembled into the designed shape on the processing platform and spot welded. Then they are placed on the operating table for fixed welding. However, the existing H-beam positioning device on the operating table is cumbersome to operate and cannot fully position all parts of the H-beam. This makes it easy for small-angle movements to occur during the welding process, resulting in relatively low welding accuracy of the steel components. Summary of the Invention

[0004] To improve the welding accuracy of steel structures, this application provides a positioning device and method for I-beam steel components in steel structures.

[0006] A positioning device for steel structure I-beams includes a mounting base with two sets of movable components on the mounting base. Each set of movable components includes two sleeve rings, which are coaxially arranged. A rotating ring is rotatably arranged inside each sleeve ring, and the rotating ring is coaxial with the sleeve ring. The rotating ring rotates about the axis of the sleeve ring. An H-beam is sleeved inside the rotating ring. A first fixing member is provided inside the rotating ring. The first fixing member is used to drive the H-beam to be coaxial with the rotating ring and fix the H-beam inside the rotating ring.

[0007] The mounting base is provided with a solder paste tank, which is located between the two sets of moving parts. A coating plate is rotatably arranged in the solder paste tank, and the rotation axis of the coating plate is perpendicular to the length direction of the H-beam. A drive motor is provided in the solder paste tank to drive the coating plate to rotate and fit against the welding end of the H-beam.

[0010] Optionally, the bottom of the sleeve ring is provided with a sliding seat, which is slidably disposed within the arc-shaped track. The second driving component includes an arc-shaped rack disposed on the mounting base, the length direction of which is parallel to the length direction of the arc-shaped track. The second driving component also includes a connecting seat disposed between the two sliding seats. A first gear that meshes with the arc-shaped rack is rotatably disposed on the connecting seat. A mobile motor for driving the first gear to rotate and thus moving the sleeve ring is disposed on the connecting seat.

[0011] Optionally, the sleeve ring includes a fixed ring disposed on the sliding seat and a fastening ring hinged to the fixed ring. The rotating ring includes two semicircular rings, which are slidably disposed within the fixed ring and the fastening ring. A second fixing member is disposed on the free end of the fastening ring, which is used to fix the fastening ring to the fixed ring. The fixed ring and the fastening ring are provided with interconnected sliding grooves. The bottom of the semicircular ring is slidably disposed within the sliding groove. The first fixing member is disposed within the semicircular ring to fix the H-beam.

[0012] Optionally, the first fixing member includes a fixing seat disposed on the inner ring of the semicircular ring, the fixing seat corresponding to the semicircular ring, the first fixing member further includes a fixing plate disposed on the fixing seat, the fixing plate being slidably disposed on the fixing seat, the sliding direction of the fixing plate being perpendicular to the axial direction of the sleeve ring, a first hydraulic cylinder being disposed on the fixing seat, and the fixing plate being fixedly disposed on the piston rod of the first hydraulic cylinder.

[0013] Optionally, the mounting base surface is provided with a receiving plate, the receiving plate has a through hole communicating with the solder paste tray, the lowest end of the sleeve ring is higher than the surface of the receiving plate, the receiving plate is slidably mounted on the mounting base, the receiving plate slides in a direction perpendicular to the surface of the mounting base, and the mounting base is provided with a second hydraulic cylinder for driving the receiving plate to slide and receiving the H-beam.

[0014] Optionally, a rotating disk is rotatably mounted on the receiving plate, and the through hole is opened on the rotating disk. Two suspension rods are mounted on the rotating disk. The two suspension rods are parallel to each other and located on both sides of the H-beam. Suspension ropes are mounted on the suspension rods, and the ends of the suspension ropes are used to fix the H-beams to the part that is not supported on the receiving plate.

[0015] Optionally, the fixed plate is rotatably provided with movable wheels, the rotation axis of the movable wheels is parallel to the bearing surface of the mounting seat, the H-beam is pressed between the movable wheels on both sides, and the fixed ring is rotatably provided on the bearing seat, the rotation axis of the fixed ring is perpendicular to the top surface of the bearing seat.

[0016] Secondly, this application provides a method for positioning I-beams in steel structures, which adopts the following technical solution:

[0017] Optionally, a method for positioning steel structural I-beams, using a positioning device for steel structural I-beams, further includes;

[0018] S1: When welding steel trusses, if it is necessary to lengthen a single H-beam, first place the two H-beams to be welded inside the collar and adjust the direction of the H-beams so that the two H-beams are coaxial. At this time, the welding ends of the two H-beams are located inside the solder paste tank opening. Then, the coating board is driven by the drive motor to rotate out of the solder paste tank and press against the ends of the H-beams. The coating board applies solder paste to the ends of the H-beams.

[0019] S2: Then the moving wheel rotates to drive the H-beams to come closer together and connect, so as to press the solder paste onto the welding surface of the H-beams. Then, an open flame is used to heat the welding surface of the H-beams to melt the solder paste and temporarily fix the H-beams. After the H-beams are fixed, they are fixed by welding.

[0020] S3: When the H-beam is lengthened, if the H-beam is welded to the web or flange of the H-beam, and the H-beam to be welded is perpendicular to the H-beam, the H-beam is fitted into the connecting ring, and the suspension rope is fixed to the H-beam to be welded. Then the connecting ring is moved along the arc track, which moves the H-beam to be perpendicular to the H-beam. Then the moving wheel drives the two H-beams to abut against each other and are welded.

[0021] S4: When welding the inclined H-beams inside the steel truss, the welding end face of the H-beam is inclined. The H-beam is fitted into the sleeve ring, and then the direction of the H-beam is adjusted so that the welding end face of the H-beam is parallel to the coating plate. After the coating plate is coated with solder paste, the position of the sleeve ring is moved, which drives the H-beam to move to the inclined installation position. Then the welding end face of the H-beam is placed against the H-beam, and then the H-beam is welded.

[0022] S5: After welding the oblique H-beam, open the sleeve ring, then move the H-beam to the next welding point. Then, put the oblique H-beam back into the moving sleeve ring, move the H-beam, and adjust the H-beam to another welding direction before welding the H-beam.

[0023] S6: After the receiving ring moves the H-beam to the welding point, the receiving plate moves to the bottom of the H-beam to support it, thereby improving the welding stability of the H-beam.

[0024] In summary, this application includes at least one of the following beneficial technical effects:

[0025] When welding H-beams, the H-beams to be welded are fitted into the connecting ring, and the first fastener is used to fix the H-beams in the rotating ring. Then, the drive motor drives the coating plate to apply solder paste to the ends of the H-beams. The two H-beams are then joined together, and the solder paste is used to initially fix the H-beams. Finally, the H-beams are fixed together by welding. When it is necessary to adjust the welding direction of the H-beams, the H-beams are rotated so that the flanges or webs of the H-beams face the H-beams to be welded, which facilitates the welding of the H-beams.

[0026] When welding H-beams vertically, the H-beams are fitted inside the sleeve ring, and the H-beams are pushed to move along the arc track until they are perpendicular to each other. Then, the H-beams are pushed to abut against each other to perform welding.

[0027] When welding H-beams at an angle, after the H-beams are fitted into the sleeve ring, the H-beams are pushed to move along the arc track. First, the H-beams are made perpendicular to each other. Then, one end of the H-beams is pushed to make the H-beams arranged at an angle. Finally, the H-beams are pushed to abut against each other and welding is performed. Attached Figure Description

[0041] The following is in conjunction with the appendix Figure 1 -Appendix Figure 8 This application will be described in further detail.

[0042] This application discloses a positioning device for I-beam steel components in a steel structure. (Refer to...) Figure 1 The positioning device for steel structure I-beams includes a mounting base 1, on which two sets of moving parts 2 are provided. Each set of moving parts 2 includes two sleeve rings 21, which are coaxially arranged. A rotating ring 22 is rotatably arranged inside the sleeve ring 21. The rotating ring 22 is coaxial with the sleeve ring 21 and rotates about the axis of the sleeve ring 21. The H-beam 3 is sleeved inside the rotating ring 22. A first fixing member is provided inside the rotating ring 22. The first fixing member is used to drive the H-beam 3 to be coaxial with the rotating ring 22 and fix the H-beam 3 inside the rotating ring 22.

[0043] When welding H-beam 3, H-beam 3 is fitted into sleeve ring 21 and rotating ring 22, and then fixed in rotating ring 22 by first fixing member. Then, H-beam 3 is pushed until it abuts against each other, and then the welding end face of H-beam 3 is fixed. During the welding process, because H-beam 3 is fixed in rotating ring 22, the possibility of position displacement of H-beam 3 during welding is reduced, thereby improving the welding quality of H-beam 3. Furthermore, when it is necessary to weld H-beam 3 to flange plate or web plate, H-beam 3 is rotated so that H-beam 3 rotates in sleeve ring 21 to adjust the welding surface of H-beam 3, thereby facilitating the welding operation of H-beam 3.

[0044] Reference Figure 1 and Figure 2 To further reduce the possibility of H-beam 3 shifting during welding, a solder paste tank 4 is provided on the mounting base 1. The solder paste tank 4 is located between two sets of moving parts 2. A coating plate 5 is rotatably installed inside the solder paste tank 4. The rotation axis of the coating plate 5 is perpendicular to the length direction of the H-beam 3. A drive motor is installed inside the solder paste tank 4 to drive the coating plate 5 to rotate and fit against the welding end of the H-beam 3. When the two H-beams 3 are coaxial and the welding end face is above the opening of the solder paste tank 4, the drive motor is then started. The drive motor drives the coating plate 5 to rotate. Since the coating plate 5 is embedded in the solder paste tank 4, when the coating plate 5 rotates, it drives the solder paste attached to the surface of the coating plate 5 to be applied to the end face of the H-beam 3. Then, the H-beams 3 are pushed to abut against each other, causing the H-beams 3 to compress the solder paste. The solder paste is then heated by a heating device such as a flame gun. After the solder paste cools and solidifies, it initially fixes the H-beam 3. Then, the H-beam 3 is fixed by welding, which further improves the welding forming effect of the H-beam 3.

[0045] Reference Figure 2 , Figure 3 and Figure 4Because the load-bearing capacity of the I-beams needs to be increased, during the welding process of the H-beams 3, it is necessary to weld diagonal braces to the sides of the long strip H-beams 3 or weld supporting steel in the vertical direction. To facilitate the adjustment of the position of the H-beams 3 on the mounting base 1, so that the H-beams 3 are welded perpendicularly to each other or obliquely, in this embodiment of the application, one set of moving parts 2 is fixedly set on the mounting base 1, and another set of moving parts 2 is slidably set on the mounting base 1. The two moving parts 2 are initially coaxial, and the sliding moving parts 2 slide to a position perpendicular to the fixed moving parts 2. The mounting base 1 is provided with a second [feature] for driving the moving parts 2 to slide. The driving component 6 includes a fixed H-beam 3 fitted inside the fixed moving component 2 and a movable H-beam 3 fitted inside the movable moving component 2. The movable H-beam is used for welding onto the fixed H-beam 3. After both the fixed H-beam 3 and the movable H-beam 3 are fitted inside the connecting ring 21, the second driving component 6 drives the movable connecting ring 21 to move on the mounting base 1, so that the movable H-beam 3 is perpendicular to the fixed H-beam 3, or the direction of the movable H-beam 3 is obliquely intersecting with the fixed H-beam 3. This allows the welding of the H-beam 3 to have multiple welding positions, thereby improving welding efficiency and welding effect.

[0046] Reference Figure 2 , Figure 3 and Figure 4 In this embodiment, the mounting base 1 is provided with two arc-shaped tracks 7, which are arc-shaped groove tracks. The arc-shaped groove tracks are opened on the surface of the mounting base 1. The angle of the arc-shaped tracks 7 is greater than 180 degrees. The two arc-shaped tracks 7 are parallel to each other. The two sleeve rings 21 in the sliding moving part 2 are slidably disposed in the arc-shaped tracks 7. After the H-beam 3 is sleeved in the sleeve ring 21, the direction of the H-beam 3 is adjusted as the sleeve ring 21 moves.

[0047] Reference Figure 6 After the movable H-beam 3 is fitted into the sleeve ring 21, when the movable H-beam 3 is perpendicular to the fixed H-beam 3, the movable H-beam 3 and the fixed H-beam 3 are first made coaxial. After the coating plate 5 applies solder paste to the end face of the movable H-beam 3, the movable H-beam 3 is pushed and moves along the arc track 7, so that the movable H-beam 3 is perpendicular to the fixed H-beam 3. Then the movable H-beam 3 is pushed to abut against the welding surface of the fixed H-beam 3. Then the solder paste is heated to initially fix the H-beam 3 and perform welding.

[0048] Reference Figure 7 and Figure 8When the movable H-beam 3 is installed obliquely on the fixed H-beam 3, because the H-beam 3 has an oblique end, after the movable H-beam 3 is fitted into the sleeve ring 21, the position of the movable H-beam 3 is adjusted so that the welding oblique surface of the movable H-beam 3 is parallel to the coating plate 5. Then, solder paste is applied to the welding oblique surface of the movable H-beam 3 through the coating plate 5. Then, the direction of the movable H-beam 3 is adjusted so that the welding oblique surface of the movable H-beam 3 is directly facing the welding surface of the fixed H-beam 3. Subsequently, the movable H-beam 3 is heated and welded to fix it.

[0049] Reference Figure 2 , Figure 3 and Figure 4 In this embodiment, a sliding seat 8 is provided at the bottom of the sleeve ring 21. The sliding seat 8 is slidably disposed within the arc-shaped track 7. The second driving member 6 includes an arc-shaped rack 61 disposed on the mounting base 1. The length direction of the arc-shaped rack 61 is parallel to the length direction of the arc-shaped track 7. The second driving member 6 also includes a connecting seat 62 disposed between the two sliding seats 8. A first gear 63 is rotatably disposed on the connecting seat 62 and meshes with the arc-shaped rack 61. A moving motor 64 is disposed on the connecting seat 62 to drive the first gear 63 to rotate and thus move the sleeve ring 21. When adjusting the direction of the moving H-beam 3, the moving motor 64 is started. The moving motor 64 drives the first gear 63 to rotate. During the rotation, the first gear 63 moves on the arc-shaped rack 61, thereby moving the connecting seat 62. The connecting seat 62 moves between the two arc-shaped tracks 7, thereby moving the moving H-beam 3, and thus adjusting the position of the moving H-beam 3. The operation is simple and convenient.

[0050] Reference Figure 2 and Figure 5 In this embodiment, to facilitate the fitting of the H-beam 3 into the sleeve ring 21, the sleeve ring 21 includes a fixed ring 211 disposed on the sliding seat 8 and a fastening ring 212 hinged to the fixed ring 211. The rotating ring 22 includes two semicircular rings 221, which are slidably disposed within the fixed ring 211 and the fastening ring 212. A second fixing member is disposed on the free end of the fastening ring 212. The second fixing member is used to fix the fastening ring 212 to the fixed ring 211. The second fixing member includes a latch 2 disposed on the fastening ring 212. 3. The locking tongue 24 set on the fixed ring 211 is fixed to the lock buckle 23 to fix the locking ring 212 to the fixed ring 211. The operation is simple and convenient. When the H-beam 3 is moved into the sleeve ring 21, the fixing effect of the locking ring 212 is released. Then the locking ring 212 is rotated to open the fixed ring 211. The fixed ring 211 drives the semi-circular ring 221 to open with each other. Then the H-beam 3 is hoisted into the semi-circular ring 221, and the locking ring 212 is fixed to the fixed ring 211 to fix the H-beam 3 in the rotating ring 22.

[0051] Reference Figure 2 and Figure 5 In this embodiment of the application, the fixing ring 211 and the fastening ring 212 are provided with interconnected sliding grooves, the bottom of the semi-circular ring 221 is integrally formed with a slider that is slidably disposed in the sliding groove, and the first fixing member is disposed in the semi-circular ring 221 to fix the H-beam 3.

[0052] Reference Figure 2 and Figure 5 In this embodiment, the first fixing member includes a fixing seat 9 disposed within the inner ring of the semicircular ring 221, the fixing seat 9 corresponding to the semicircular ring 221. The first fixing member also includes a fixing plate 10 disposed on the fixing seat 9, the fixing plate 10 being slidably disposed on the fixing seat 9, the sliding direction of the fixing plate 10 being perpendicular to the axial direction of the sleeve ring 21. A first hydraulic cylinder 11 is disposed on the fixing seat 9, and the fixing plate 10 is fixedly disposed on the piston rod of the first hydraulic cylinder 11. When the H-beam 3 is sleeved inside the rotating ring 22, the first hydraulic cylinder 11 is activated, the first cylinder pushes the fixing plate 10 to slide, and the fixing plates 10 on both sides move closer to each other, so as to clamp the H-beam 3 between the fixing plates 10 on both sides, making the operation simple and convenient.

[0053] Reference Figure 1 and Figure 2 After the positions of the fixed H-beam 3 and the movable H-beam 3 are adjusted, to further improve the welding stability of the fixed H-beam 3 and the movable H-beam 3, a receiving plate 12 is provided on the surface of the mounting base 1. The receiving plate 12 has a through hole 13 communicating with the solder paste tray 4. Furthermore, the receiving plate 12 has an arc-shaped notch 14 communicating with the arc-shaped track 7. Furthermore, the two arc-shaped notches 14 are interconnected, so that when the receiving plate 12 rises, it abuts against the bottom surface of the H-beam 3 through the connecting seat 62. The lowest end of the sleeve ring 21 is higher than the surface of the receiving plate 12. The receiving plate 12 is slidably mounted on the mounting base 1. The receiving plate 12 is vertically... The H-beam 3 slides directly in the direction of the mounting base 1. The mounting base 1 is equipped with a second hydraulic cylinder 15 for driving the receiving plate 12 to slide and receive the H-beam 3. After the positions of fixing and moving the H-beam 3 are adjusted, because the H-beam 3 is located in the middle of the sleeve ring 21, the receiving point of the H-beam 3 only has the point of contact with the sleeve ring 21, resulting in a relatively poor fixing effect of the H-beam 3. At this time, the second hydraulic cylinder 15 drives the receiving plate 12 to slide, and the receiving plate 12 slides in the direction away from the mounting base 1, so that the receiving plate 12 supports the bottom of the H-beam 3, thereby improving the welding stability of the H-beam 3.

[0054] Reference Figure 1 and Figure 2In this embodiment, because the length of the H-beam 3 is greater than the length of the mounting base 1, the suspended side of the H-beam 3 tends to fall downwards after being placed on the receiving plate 12. This causes the connecting ring 21 to tend to rise, making it difficult for the H-beam 3 to remain horizontal for welding. Therefore, in this embodiment, a rotating disk 16 is rotatably mounted on the receiving plate 12, and a through hole 13 is formed on the rotating disk 16. Two suspension rods 17 are mounted on the rotating disk 16. The two suspension rods 17 are parallel to each other and located on both sides of the H-beam 3. Suspension ropes 18 are mounted on the suspension rods 17, and the ends of the suspension ropes 18 are used to fix the part of the H-beam 3 that is not supported on the receiving plate 12. Furthermore, the suspension... A winding motor is installed on the tie rod 17, and the suspension ropes 18 are wound onto the output shaft of the winding motor. The ends of the two suspension ropes 18 are equipped with tightening straps, which are used to attach to the suspended ends of the H-beam 3. After the H-beam 3 is supported on the receiving plate 12, the tightening straps are attached to the ends of the H-beam 3. Then, the winding motor is started, and the winding motor winds up the suspension ropes 18 to tighten them, thereby suspending the ends of the H-beam 3 and keeping it in a horizontal position to facilitate welding operations. Under the action of the suspension ropes 18, the suspension ropes 18 apply an oblique tension to the H-beam 3. The oblique tension pulls the H-beam 3 with a tendency to move towards the inside of the receiving plate 12, thereby making the H-beam 3 to be welded fit tightly together and improving the welding effect of the H-beam 3.

[0055] In this embodiment, a movable wheel is rotatably provided on the fixed plate 10. The rotation axis of the movable wheel is parallel to the bearing surface of the mounting base 1. The H-beam 3 is pressed between the movable wheels on both sides. Under the action of the movable wheel, it is convenient to push the fixed H-beam 3 to adjust the welding point of the H-beam 3 so as to carry out the welding of the next point, thereby facilitating the welding operation of the steel truss.

[0056] To facilitate adjustment of the direction of the moving H-beam 3, the fixing ring 211 is rotatably mounted on the receiving seat, and the rotation axis of the fixing ring 211 is perpendicular to the top surface of the receiving seat.

[0057] The implementation principle of the positioning device for a steel structure I-beam in this application embodiment is as follows:

[0058] When welding H-beam 3, H-beam 3 is fitted into sleeve ring 21 and rotating ring 22, and then fixed in rotating ring 22 by first fixing member. Then, H-beam 3 is pushed until it abuts against each other, and then the welding end face of H-beam 3 is fixed. During the welding process, because H-beam 3 is fixed in rotating ring 22, the possibility of position displacement of H-beam 3 during welding is reduced, thereby improving the welding quality of H-beam 3. Furthermore, when it is necessary to weld H-beam 3 to flange plate or web plate, H-beam 3 is rotated so that H-beam 3 rotates in sleeve ring 21 to adjust the welding surface of H-beam 3, thereby facilitating the welding operation of H-beam 3.

[0059] After the movable H-beam 3 is fitted into the sleeve ring 21, when the movable H-beam 3 is perpendicular to the fixed H-beam 3, first, the movable H-beam 3 and the fixed H-beam 3 are made coaxial. After the coating plate 5 applies solder paste to the end face of the movable H-beam 3, the movable H-beam 3 is pushed, and the movable H-beam 3 moves along the arc track 7, making the movable H-beam 3 perpendicular to the fixed H-beam 3. Then, the movable H-beam 3 is pushed to abut against the welding surface of the fixed H-beam 3. Then, the solder paste is heated to initially fix the H-beam 3 and perform welding fixation. When the movable H-beam 3... 3. When the H-beam 3 is installed obliquely on the fixed H-beam 3, the end of the H-beam 3 is opened with an oblique surface. At this time, after the movable H-beam 3 is sleeved in the sleeve ring 21, the position of the movable H-beam 3 is adjusted so that the welding oblique surface of the movable H-beam 3 is parallel to the coating plate 5. Then, solder paste is applied to the welding oblique surface of the movable H-beam 3 through the coating plate 5. Then, the direction of the movable H-beam 3 is adjusted so that the welding oblique surface of the movable H-beam 3 is directly facing the welding surface of the fixed H-beam 3. Then, the movable H-beam 3 is heated and welded to fix it.

[0060] This application discloses a method for positioning I-beams in a steel structure, referring to... Figure 1 , Figure 6 , Figure 7 and Figure 8 The positioning device using steel structure I-beams also includes;

[0061] S1: When welding steel trusses, if it is necessary to lengthen the length of a single H-beam 3, first place the two H-beams 3 to be welded in the sleeve ring 21 and adjust the direction of the H-beams 3 so that the two H-beams 3 are coaxial. At this time, the welding ends of the two H-beams 3 are located in the opening of the solder paste tank 4. Then, the coating plate 5 is driven by the drive motor to rotate out of the solder paste tank 4 and press against the end of the H-beam 3. The coating plate 5 applies solder paste to the end of the H-beam 3.

[0062] S2: Then the moving wheel rotates to drive the H-beams 3 to come closer together and connect, so as to press the solder paste onto the welding surface of the H-beams 3. Then, an open flame is used to heat the welding surface of the H-beams 3 to melt the solder paste and temporarily fix the H-beams 3. After the H-beams 3 are fixed, they are fixed by welding.

[0063] S3: When the H-beam 3 is lengthened, if the H-beam 3 is welded to the web or flange of the H-beam 3, and the H-beam 3 to be welded is perpendicular to the H-beam 3, the H-beam 3 is fitted into the connecting ring 21, and the suspension rope 18 is fixed to the H-beam 3 to be welded. Then the connecting ring 21 is moved so that the connecting ring 21 moves along the arc track 7, thereby moving the H-beam 3 to be perpendicular to the H-beam 3. Then the moving wheel drives the two H-beams 3 to abut against each other and then weld them.

[0064] S4: When welding the inclined H-beam 3 inside the steel truss, the welding end face of the H-beam 3 is inclined. The H-beam 3 is fitted into the sleeve ring 21, and then the direction of the H-beam 3 is adjusted so that the welding end face of the H-beam 3 is parallel to the coating plate 5. After the coating plate 5 is coated with solder paste, the position of the sleeve ring 21 is moved, which drives the H-beam 3 to move to the inclined installation position. Then the welding end face of the H-beam 3 is placed against the H-beam 3, and then the H-beam 3 is welded.

[0065] S5: After welding the oblique H-beam 3, open the sleeve ring 21, then move the H-beam 3 to the next welding point. Then, put the oblique H-beam 3 back into the moving sleeve ring 21, move the H-beam 3, and adjust the H-beam 3 to another welding direction before welding the H-beam 3.

[0066] S6: After the receiving ring moves the H-beam 3 to the welding point, the receiving plate 12 moves to the bottom surface of the H-beam 3 to support the H-beam 3, thereby improving the welding stability of the H-beam 3.
