The connecting block 1501 in the welding mechanism 15 is connected to the rolling wheel spot weld 1502 through a double-ear plate. The adjustment plate 1503 is located on both sides of the rolling wheel spot weld 1502, and the adjustment plate 1503 is connected to the connecting block 1501 through a hinge. A placement groove 1531 is opened in the adjustment plate 1503, and replacement holes 1532 are opened on both sides of the placement groove 1531.

The limiting column 16 is provided with a through hole through the adjustment plate 1503. The limiting column 16 mainly plays a positioning role. The auxiliary wheel 1505 is fixedly connected to the limiting column 16 through the double ear plate. When the auxiliary wheel 1505 is against the intersection of the steel bars, the supporting force exerted on the auxiliary wheel 1505 is transmitted to the buffer 18 through the supporting plate 17. The buffer 18 is made of polyurethane material or rubber material. When the buffer 18 is used for too long and is damaged, it can be taken out and replaced through the replacement hole 1532.

[0032] refer to Figure 1 and Figure 2 After a part of the steel frame is welded, the steel frame conveying equipment can be stopped, and the hooking mechanism 12 in one of the adjustable door frames can be used to drag the steel frame forward, and the welding mechanism 15 in the other adjustable door frame can be used to weld. It can also be welded from both sides of the steel frame to the middle at the same time. The adjustable door frame is composed of a bottom slide 2, a sliding plate 3, a column 4, a drive box 8 and a displacement block 9. The first lifting blocks 5 are respectively slidably connected to the columns 4 and are spaced apart. They can slide up and down along the columns 4 to facilitate height adjustment; the welding mechanism 15 is respectively set on one side of each first lifting block 5, which can perform welding operations on steel bars. Reference Figure 1 and Figure 2The base frame 1 is a rectangle formed by welding a number of metal rods together, and bottom slides 2 are provided above both sides of the base frame 1. Horizontal rail slides 121 are fixed above both sides of the base frame 1 and above the bottom slides 2. The bottom slides 2 are connected to the horizontal rail slides 121 provided on the base frame 1 through sliders. The bottom of each column 4 is fixedly connected to the sliding plate 3, and the sliding plate 3 is connected to the horizontal rail slide 121 provided on the bottom slide 2 through a slider, so that the two bottom slides 2 can slide freely on the base frame 1, and the columns 4 can slide freely on the bottom slide 2 through the sliding plate 3. Each group of columns 4 is provided with two at intervals, and are slidably connected to both sides of the bottom slide 2 through the sliding plate 3. The bottom slide 2 is like a sliding base, which is generally made of high-strength metal material, such as steel, to ensure sufficient strength and stability. Reference Figure 1 and Figure 2 , two racks 401 are spaced apart on each column 4, and the first lifting block 5 is engaged with the rack 401 through a gear, and is adjusted to rise and fall by the first power source 6, which is arranged on one side of the first lifting block 5. The first lifting block 5 is equipped with a gear engaged with the rack 401. The first power source 6 uses a servo motor, which is connected to the gear through a reducer to drive the gear to rotate, so that the first lifting block 5 moves up and down along the column 4. The second lifting block 7 is slidably connected to the top of each column 4, and the connection method can be an electric slide rail. The drive box 8 is respectively arranged on one side of each two second lifting blocks and the bottom slide 2, and the drive box 8 arranged on the second lifting block 7 is connected to the electric slide rail to facilitate the adjustment of the distance between the two columns 4. The second lifting block 7 is also connected to the slide on the column 4 through a slider. Reference Figure 2 The first lifting block 5, the second lifting block 7 and the displacement block 9 are connected to the angle plate 11 by bolts, and the hooking mechanism 12, the rotating mechanism 14 and the welding mechanism 15 are arranged on the angle plate 11. The angle plate 11 can be made of a steel plate with multiple bolt holes on it for easy connection with the first lifting block 5 and the displacement plate 9. The function of the angle plate 11 is to provide an installation base and angle adjustment function for other mechanisms. The displacement block 9 is slidably connected to the drive box 8, and a screw rod is provided in the drive box 8, and the screw rod drives the displacement block 9 to move, and the second power source 10 drives the screw rod to rotate to complete the displacement of the welding mechanism 15.

[0033] refer to Figure 3 and Figure 4The welding mechanism 15 is regulated and rotated by the rotating mechanism 14. The connecting block 1501 in the welding mechanism 15 is connected to the roller pressure wheel spot welding 1502 via a double-ear plate. Adjustment plates 1503 are provided on both sides of the roller pressure wheel spot welding 1502, and the adjustment plates 1503 are movably connected to the connecting block 1501. The two sides of the spring 1504 are respectively connected to the connecting block 1501 and the adjustment plates 1503. The connecting block 1501 is connected to the roller pressure wheel spot welding 1502 via the double-ear plate. This connection method is relatively flexible and can allow the roller pressure wheel spot welding 1502 to rotate to a certain extent. The roller pressure wheel spot welding 1502 is generally made of copper because copper alloy has good electrical and thermal conductivity, which is suitable for spot welding operations. The spring 1504 can play a certain buffering role, but is mainly used for connection.

[0034] The implementation principle of a retractable gantry multi-spot synchronous welding machine for a steel bar skeleton in this embodiment 1 is as follows: the steel bar skeleton is composed of a plurality of rectangular steel bars and steel bars, and the steel bars need to be welded at the four inner corners of the rectangular steel bars. If the steel bar skeleton is provided with different sizes, it is necessary to adjust the height of the first lifting block 5 and the second lifting block 7, and the interval between every two columns 4. After adjusting to the appropriate distance, the hook 1203 hooks the steel bar and is retracted by the first cylinder 1202 to be supported in the dovetail groove 1241 provided on the supporting plate 1204. At this time, the steel bar intersects with each corner of the rectangular steel bar, the second cylinder 1403 extends and supports the auxiliary wheel 1505 on the rectangular steel bar, and the spring 1504 is squeezed to rotate with the adjusting plate 1503, and finally the roller wheel spot welding 1502 is supported at the intersection of each steel bar and the rectangular steel bar for spot welding. When second cylinder 1403 suddenly extends, the force on auxiliary wheel 1505 increases, making it susceptible to damage. However, spring 1504 absorbs some of the sudden force and cushions the impact on roller spot weld 1502, extending its service life. Hook 1203 hooks onto the rebar, and auxiliary wheel 1505 presses against the rectangular rebar, pushing spring 1504 toward the sides with adjustment plate 1503 to ensure better contact between the intersection of the rebar and the rectangular rebar. When welding a cylindrical rebar cage, hook 1203 is retracted to its shortest position by first cylinder 1202. Rotating mechanism 14 then adjusts the angle of welding mechanism 15 to the intersection of the cylindrical rebar cage. Second cylinder 1403 adjusts roller-type spot welders 1502 to contact the intersection for spot welding. The rebar cage vibrates as it rotates, and springs 1504 on either side of auxiliary wheels 1505 absorb the vibration. The vibration from roller-type spot welders 1502 is then transmitted to springs 1504 via connecting blocks 1501. The welding mechanisms, mounted on two adjustable portals and arranged circumferentially, can simultaneously weld multiple intersections of the rebar cage and adapt to various cage and rebar cage applications.

[0035] Example 2: Example 2 of the present application provides a multi-point synchronous welding machine with a retractable gantry for a steel frame.

[0036] refer to Figure 1 and Figure 2 The first lifting block 5 is driven by a first power source 6, and the first lifting block 5 can be raised and lowered on the column 4. The drive box 8 is connected to the second lifting block 7 via an electric slide, and the second lifting block 7 can be driven by an electric slide. Alternatively, the second lifting block 7 can be provided with a gear and engages with the rack 401 and is driven by a servo motor. The second lifting block 7 is set at the top of each column 4, and the drive box 8 is connected to the second lifting block 7 via an electric slide. Two adjustable door frames can move horizontally on the base frame 1. The adjustable door frames are composed of a bottom slide 2, a sliding plate 3, a column 4 and a drive box 8. Both the bottom slide 2 and the base frame 1 are provided with a horizontal rail slide 121. The two columns 4 can adjust the spacing on the bottom slide 2, and the columns 4 adjust the spacing on the base frame 1 as the bottom slide 2 adjusts.

[0037] refer to Figure 3 and Figure 4 , two first fixed plates 1201 in the hooking mechanism 12 are arranged at intervals, and the first cylinder 1202 is fixedly connected between the two first fixed plates 1201, and the protruding end of the first cylinder 1202 is connected to the hook 1203. One side of the two first fixed plates 1201 is fixedly connected to the angle plate 11 and the supporting plate 1204, and a dovetail groove 1241 is provided on one side of the supporting plate 1204. The first fixed plate 1201 and the second fixed plate 13 are generally made of iron plates and fixed to the angle plate 11 by welding or bolting. The second fixed plate 13 is arranged at intervals on the other side of the two first fixed plates 1201, and the second fixed plate 13 provides an installation basis for the subsequent rotating mechanism 14. The first cylinder 1202 can be a pneumatic cylinder, which uses compressed air to push the piston rod to move, thereby driving the extension and retraction of the hook 1203. The hook 1203 can be made of high-strength steel to ensure that it can firmly hook the steel bar. The dovetail groove 1241 on the supporting plate 1204 can cooperate with other components to play a role in positioning and guiding. Figure 3 and Figure 4 Two bearings 1401 are spaced apart in the rotating mechanism 14. The second fixed plate 13 is connected to the second cylinder 1403 via the bearings 1401. One side of the second cylinder 1403 is connected to the third power source 1402, and the other side of the extended end is connected to the welding mechanism 15. The second cylinder 1403 can be a hydraulic cylinder, which can provide greater thrust than a pneumatic cylinder. The extended end of the second cylinder 1403 is connected to the welding mechanism 15. When the welding mechanism 15 needs to adjust its rotation direction, the third power source 1402 rotates the welding mechanism 15 via the bearings 1401. The first power source 6, the second power source 10, and the third power source 1402 are all servo motors.

[0038] refer to Figure 4 and Figure 5 When the roller-pressing wheel spot weld 1502 is subjected to external force, the spring 1504 can be compressed or stretched to protect the roller-pressing wheel spot weld 1502 and the adjustment plate 1503. The roller-pressing wheel spot weld 1502 is provided with a first annular groove 1521 and is connected to the power supply via a cable. The top of the adjustment plate 1503 is connected to the connecting block 1501 via a hinge. The inner cavity of the adjustment plate 1503 is provided with a placement groove 1531, and displacement holes 1532 are machined on both sides of the placement groove 1531. The buffer 18 passes through the displacement holes 1532 and is placed in the placement groove 1531. The auxiliary wheel 1505 is fixedly connected to the limiting column 16 via a double-ear plate. The limiting column 16 passes through the through hole provided in the adjustment plate 1503 and is fixedly connected to the supporting plate 17.

[0039] refer to Figure 4 and Figure 5 When the auxiliary wheel 1505 is against the intersection of the steel bars, the pressure exerted on the auxiliary wheel 1505 is transferred to the buffer 18. When the buffer 18 is damaged after long-term use, the buffer 18 can be removed from the replacement hole 1532 and replaced. A second annular groove 1551 is provided on the auxiliary wheel 1505, and a buffer rubber is provided in the second annular groove 1551. When the auxiliary wheel 1505 is against the intersection of the steel bars, the buffer rubber can protect the auxiliary wheel 1505. The first annular groove 1521 and the second annular groove 1551 can better accommodate the steel bars and improve the accuracy of welding. The auxiliary wheel 1505 can also be made of copper alloy and work in conjunction with the roller spot welding 1502 to assist in completing the welding process.

[0040] The second embodiment of the present invention is a retractable gantry-type multi-point synchronous welding machine for a steel cage. The principle of operation is as follows: the column 4 can translate on the bottom slide 2, the drive box 8 is slidably connected to the column 4 via the second lifting block 7, and the drive box 8 can move up and down with the second lifting block 7. The first lifting block 5 is slidably connected to the column 4, and the welding mechanism 15, the hooking mechanism 12, and the rotating mechanism 14 are all fixedly connected to the angle plate 11, which is bolted to the first lifting block 5 and the drive box 8. When the size of the steel cage changes, the height of the first lifting block 5 and the second lifting block 7 must be readjusted. The hooking mechanism 12 now hooks the intersection of the steel bars, and at this time, the extended end of the second cylinder 1403 suddenly extends, and the auxiliary wheel 1505 in the control welding mechanism 15 is pressed against the intersection of the steel bars. The force applied to the auxiliary wheel 1505 is transmitted to the buffer 18 and absorbed. The ends of spring 1504 are connected to connecting block 1501 and adjusting plate 1503, respectively. When auxiliary wheel 1505 presses against the intersection of the rebars and slides over them, adjusting plate 1503 separates, squeezing spring 1504. The sudden downward force of second cylinder 1403 is completely absorbed by buffer 18, allowing roller spot weld 1502 to press against the intersection and perform spot welding. Roller spot weld 1502 is made of copper, which transfers heat quickly, completing the weld the moment it contacts the intersection. Roller spot weld 1502 is connected to a power source via a cable, generating resistance heat to melt the metal, thus achieving welding.

[0041] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
