Description

Technical Field

[0001] This invention belongs to the field of photovoltaic panel accessory welding technology, and particularly relates to a photovoltaic panel accessory welding fixture. Background Technology

[0002] Photovoltaic panels (also known as solar panels) are the core components for realizing photoelectric conversion. However, to apply them in practical scenarios (such as rooftops, ground surfaces, photovoltaic power stations, etc.), a series of accessories are needed to assist in the installation, fixing, support, and ensure the normal operation of the photovoltaic support system. Among these accessories, ground pile pipes are the most important, serving as the foundation and backbone of the photovoltaic support system.

[0003] In the production process of ground pile pipes, multiple nuts need to be pre-welded to the ends of the ground pile pipes to lay the foundation for subsequent assembly with other accessories into a bracket. In the existing welding operation, the fixing of ground pile pipes and the placement of nuts usually adopt a mechanical and manual assistance mode: the worker first inserts the ground pile pipe horizontally into the positioning post, and the worker adjusts the initial posture of the ground pile pipe so that a row of bolt holes along its circumferential length direction is centered and facing upward. Then, the locking mechanism on the positioning post fixes the pipe body and determines the initial fixed state of the ground pile pipe. Subsequently, the nut is precisely placed at the bolt hole end by the worker, and finally the welding is completed by welding gun.

[0004] However, this operating mode has revealed significant drawbacks in actual mass production: 1. The single row of bolt holes on the surface of the pile pipe needs to be manually adjusted to be centered and facing upwards. Workers often need to use auxiliary tools for positioning and repeated calibration, which not only consumes a lot of time but also makes it difficult to avoid positioning deviations caused by visual errors or operational deviations, directly affecting the accuracy of subsequent nut placement. 2. The placement of nuts relies entirely on manual operation. Workers need to align each nut with the bolt hole one by one, which is not only labor-intensive and inefficient, but also prone to misalignment of nuts and bolt holes if slight negligence occurs, leading to quality problems such as incomplete welding and misaligned welding after welding, increasing the rework rate.

[0005] In summary, welding large quantities of ground pile pipes requires a significant amount of time for securing the pipes to the nuts, reducing welding quality and greatly extending the production cycle. Therefore, a welding fixture for photovoltaic panel accessories is urgently needed to solve these problems. Summary of the Invention

[0006] To address the aforementioned problems, this invention provides a photovoltaic panel accessory welding fixture, which solves the problems mentioned in the background section.

[0007] To achieve the above objectives, this application provides the following technical solution: The present invention provides a photovoltaic panel accessory welding fixture, including a mounting base. A hollow positioning post is rotatably mounted on the mounting base. A rotating mechanism is shared between the mounting base and the positioning post. A first alignment locking mechanism is mounted on the positioning post, and a second alignment locking mechanism is also mounted above the positioning post. The first alignment locking mechanism includes multiple columnar slides that can slide radially along the positioning post. Multiple slides at the same position are evenly distributed around the positioning post. A first alignment component is mounted on the end face of the slide away from the central axis of the positioning post, and a first driving component is mounted on the positioning post. The second alignment and locking mechanism includes a storage cylinder connected to an external mobile device and open at the lower end. A cylindrical positioning post is coaxially fixed inside the storage cylinder. Multiple inner support locking plates are evenly distributed along the circumference of the positioning post, with the lower ends of the inner support locking plates protruding beyond the lower end of the threaded storage cylinder. A driving assembly is shared between the storage cylinder and the positioning post, and a second alignment assembly for aligning the nut is also shared between the driving assembly and the storage cylinder. The driving assembly controls the slide to move the corresponding alignment assembly towards the threaded hole on the surface of the ground pile pipe, aligning the ground pile pipe relative to the positioning post in a preset posture while simultaneously locking it. The driving assembly alternately controls the second alignment assembly and the inner support locking plates to align and lock the nut respectively.

[0008] According to an advantageous embodiment, the rotating mechanism includes a motor fixedly mounted on a mounting base, the output shaft of the motor being connected to the surface of the positioning post via a gear set.

[0009] According to an advantageous embodiment, the surface of the positioning post is provided with a plurality of sliding holes corresponding to the threaded holes on the surface of the ground pile pipe. A guide sleeve is fixedly provided at the inner port of the sliding hole. The slide block is slidably disposed between the sliding hole and the corresponding guide sleeve. Two return springs are fixedly provided on the side wall of the slide block near the inner port of the positioning post, symmetrical to each other with respect to the center of the slide block. The other end of the return spring is fixedly connected to the corresponding position of the inner wall of the positioning post.

[0010] According to an advantageous embodiment, the alignment component one includes two guide blocks one and two guide blocks two. The two guide blocks one and two guide blocks two are fixedly disposed on the side end face of the slide away from the interior of the positioning post one, and the two guide blocks one and two guide blocks two are evenly staggered along the circumference of the corresponding slide. The guide blocks one and guide blocks two are respectively set as right-angled triangular structures with different inclinations.

[0011] According to an advantageous embodiment, the drive assembly one includes a drive screw rotatably disposed at the center of the positioning post one. Multiple tapered drive seats are threaded along the length of the drive screw. A guide wheel is rotatably disposed on the end face of the slide near the drive seat. The guide wheel rolls against the surface of the corresponding drive seat. Two guide rods are slidably inserted between all drive seats. The two ends of the guide rods are fixedly connected to the inner wall of the positioning post one. A motor two is fixedly disposed on the end face of the positioning post one away from the mounting seat. The output shaft of the motor two is fixedly connected to one end of the drive screw.

[0012] According to an advantageous embodiment, the interior of the storage cylinder is configured as a storage cavity with a hexagonal cross-section. The upper end of the second positioning post is fixedly connected to the middle of the upper inner wall of the storage cavity. The surface of the second positioning post is provided with a plurality of sliding holes extending along its length. The inner support locking plate is slidably connected to the corresponding sliding holes. Two symmetrical reset springs are fixedly provided on the side of the inner support locking plate near the interior of the second positioning post. The other end of the reset spring is fixedly connected to the corresponding position of the inner wall of the second positioning post.

[0013] According to an advantageous embodiment, the second drive assembly includes a drive rod rotatably disposed inside the second positioning post via a connecting plate. A plurality of polygonal cams are fixedly disposed on the surface of the drive rod. The side of the inner support locking plate near the polygonal cams is configured as an arc surface. The polygonal cams movably abut against the arc surface of the inner support locking plate. A third motor is fixedly disposed at the upper end of the storage cylinder via a bracket. The upper end of the drive rod movably passes through the upper end of the storage cylinder and the upper end of the second positioning post and is fixedly connected to the output shaft of the third motor.

[0014] According to an advantageous embodiment, the second aligning component includes two swing rods rotatably disposed on the outside of the storage cylinder and symmetrical about the center of the storage cylinder. The lower end of the swing rod is configured as a curved section and fixedly connected to a push rod, which is perpendicular to the swing rod. Two guide seats are fixedly disposed on the outside of the storage cylinder, and the guide seats are provided with strip-shaped guide holes. The upper end of the swing rod is slidably disposed in the corresponding strip-shaped guide hole. A drive disk is fixedly disposed on the upper end of the drive rotating rod. Two push-pull plates are hinged to the surface edge of the drive disk. The end of the push-pull plate away from the drive disk is hinged to the upper end of the corresponding swing rod.

[0015] Compared with the prior art, the photovoltaic panel accessory welding fixture provided by the present invention has the following beneficial effects: 1. In the present invention, by cooperating with the first and second alignment locking mechanisms and the rotation mechanism, the automatic and precise positioning and locking of the ground pile tube and the first positioning column are realized, further realizing the fully automatic feeding, guiding and alignment of the threaded holes and nuts on the surface of the ground pile tube, and can automatically switch the multiple rows of threaded holes of the ground pile tube after the welding of a single row of threaded holes is completed, realizing the automated continuous welding of multiple rows of threaded holes of the ground pile tube. The coordinated operation of each mechanism improves the degree of automation, reduces manual intervention, ensures welding stability and improves welding quality.

[0016] 2. In this invention, the positioning and locking mechanism 1 automatically locks with the positioning post 1. The operator only needs to roughly align the threaded hole of the ground pile pipe with the sliding hole 1 of the positioning post 1. The drive component 1 can drive the slide to move the positioning component 1. The slope sections of the guide block 1 and the guide block 2 with different inclinations abut against the inner wall of the inner port of the threaded hole for fine adjustment and alignment. Finally, the relative locking between the ground pile pipe and the positioning post 1 is achieved by the joint pressure of multiple sets of positioning components 1.

[0017] 3. In this invention, the second alignment and locking mechanism achieves automated operation through the coordinated operation of multiple structures: the hexagonal storage cavity of the storage cylinder initially limits the nut position, and the inner support locking plate can first lock the nut in the storage cylinder in the center. When discharging, the inner support locking plate retracts, so that the nut falls accurately to the threaded hole position under the guidance of the inner support locking plate; then the second alignment component completes the alignment by clamping the nut on two symmetrical horizontal sections, and finally the inner support locking plate expands outward again to achieve centering and locking, reducing the labor intensity of workers and ensuring accurate alignment between the nut and the threaded hole.

[0028] The following is in conjunction with the appendix Figure 1 -Appendix Figure 9 This application will now be described in further detail.

[0029] Please refer to the following: Figure 1 and Figure 2 A welding fixture for photovoltaic panel accessories is used for processing ground pile pipe 11 in photovoltaic panel accessories. The fixture includes a mounting base 1, a hollow positioning post 2 rotatably mounted on the mounting base 1, a rotating mechanism 3 shared between the mounting base 1 and the positioning post 2, a first alignment locking mechanism 4 mounted on the positioning post 2, and a second alignment locking mechanism 5 mounted above the positioning post 2.

[0030] In practice, after the ground pile pipe 11 is fitted onto the positioning post 2, the alignment and locking mechanism 4 automatically aligns and locks the ground pile pipe 11 according to a predetermined posture, ensuring that the single row of threaded holes 12 on the ground pile pipe 11 are centered and facing upwards. Simultaneously, the alignment and locking mechanism 5 guides the nut 10 (a hexagonal nut in this design) to the center for placement, then aligns and locks it in the center. Combined with external welding equipment, the nut 10 is welded to the ground pile pipe 11. After all the nuts 10 have been welded to one row of threaded holes 12 on the ground pile pipe 11, the rotating mechanism 3, in conjunction with the alignment and locking mechanism 4, can rotate the pipe by a certain angle (90° in this design). This process repeats the automatic placement, clamping, and welding of the nut 10, ultimately completing the welding of the ground pile pipe 11. This achieves automatic centering, fixing, and locking of the ground pile pipe 11, and automatic placement, guidance, centering, alignment, and locking of the nut 10.

[0031] See Figure 1 and Figure 2 The rotating mechanism 3 includes a motor fixedly mounted on the mounting base 1. The output shaft of the motor and the surface of the positioning column 2 are connected by a gear set. The motor, in conjunction with the gear set, controls the rotation of the positioning column 2, which in turn drives the ground pile tube 11, which is locked by the alignment and locking mechanism 4, to rotate.

[0032] See Figure 2 and Figure 3 The alignment and locking mechanism 4 includes multiple cylindrical slide blocks 41 that can slide radially along the positioning post 2. These slide blocks 41 are evenly distributed around the circumference of the positioning post 2. The surface of the positioning post 2 has multiple sliding holes 6 corresponding to the threaded holes 12 on the surface of the ground pile pipe 11. A guide sleeve is fixedly installed at the inner end of each sliding hole 6. The slide block 41 is slidably positioned between the sliding hole 6 and the corresponding guide sleeve. Two return springs (not shown in the figure) are fixedly installed on the side wall of the slide block 41 near the inner end of the positioning post 2, symmetrical to each other around the central axis of the slide block 41. The other end of each return spring is fixedly connected to a corresponding position on the inner wall of the positioning post 2, allowing the slide block 41 to automatically reset after losing the pressure of the driving component 43. An alignment component 42 is installed on the end face of the slide block 41 away from the central axis of the positioning post 2, and a driving component 43 is installed on the positioning post 2. After the workers place the ground pile tube 11 onto the surface of the positioning post, they need to roughly align the single row of threaded holes 12 on the ground pile tube 11 with the sliding holes 6 on the positioning post 2. Then, the drive assembly 43 drives the slide block 41 to move outward, causing the alignment assembly 42 to move toward the inner port of the corresponding threaded hole 12 on the surface of the ground pile tube 11. This forces the ground pile tube 11 to make local minor adjustments to center and align with the threaded hole 12. At the same time, the alignment assembly 42 and the inner wall of the inner port of the threaded hole 12 generate a certain pressure. Multiple alignment assemblies 42 work together to apply pressure, thereby locking the positioning post 2 and the ground pile tube 11 relative to each other.

[0033] See Figure 3 and Figure 6 The alignment component 42 includes two guide blocks 421 and two guide blocks 422. Both guide blocks 421 and 422 are integrally fixed on the end face of the slide block 41 away from the positioning post 2. The guide blocks 421 and 422 are evenly staggered along the circumference of the corresponding slide block 41. Both guide blocks 421 and 422 are right-angled triangular structures with different inclinations on their ramp sections (the specific inclinations are calculated based on multiple rounds of experiments by those skilled in the art). The ramp sections of the two corresponding guide blocks 421 form a conical guide surface 7, and the ramp sections of the two corresponding guide blocks 422 form a conical guide surface 8. Figure 6 As shown; when the workers fit the ground pile pipe 11 into the positioning post 2 for rough alignment, there is often a situation where the threaded hole 12 and the sliding hole 6 are not precisely aligned. At this time, the drive assembly 43 drives the slide 41 to move towards the inner port of the corresponding threaded hole 12. Due to the inaccurate alignment between the threaded hole 12 and the sliding hole 6, there are differences in the height of the inner wall of the inner port of the threaded hole 12. The present invention, through the design of two guide blocks 421 and two guide blocks 422 with different inclinations, can ensure that after the slide 41 moves a certain distance, the slopes of the guide blocks 421 and 422 can simultaneously abut against the inner wall of the inner port of the threaded hole 12, thereby achieving the alignment of the threaded hole 12.

[0034] In actual operation, under the action of drive component 43, tapered guide surface 7 and tapered guide surface 8 move simultaneously toward the inner wall of the inner port of threaded hole 12. When threaded hole 12 does not completely correspond to sliding hole 6, both guide surfaces abut against the inner wall of different positions of the inner port of threaded hole 12 and align threaded hole 12, so that threaded hole 12 at that position completely corresponds to the corresponding sliding hole 6. At this time, the ramp section of guide block 421 and the ramp section of guide block 422 respectively align with the inner end of threaded hole 12 at that position. The inner walls of the pipes at different positions make hard contact with each other, and the ramp sections of all the corresponding guide blocks 421 and 422 at different positions on the positioning post 12 make contact with the inner wall of the threaded hole 12 at the corresponding position to generate pressure. Together, they center the ground pile pipe 11 and lock it on the positioning post 12. At the same time, if the threaded hole 12 and the sliding hole 6 are precisely matched when the ground pile pipe 11 is inserted into the positioning post 12, then the ground pile pipe 11 can be centered and locked on the positioning post 12 without needing to be straightened.

[0035] See Figures 2-4The drive assembly 43 includes a drive screw 431 rotatably positioned at the center of the positioning post 2. Multiple tapered drive seats 432 are threaded along the length of the drive screw 431. A guide wheel is rotatably mounted on the side of the slide 41 closest to the drive seat 432, and the guide wheel rolls against the surface of the corresponding drive seat 432. Two guide rods are slidably connected to all drive seats 432, and both ends of the guide rods are fixedly connected to the inner wall of the positioning post 2. A second motor is fixedly mounted on the end of the positioning post 2 away from the mounting base 1, and the output shaft of the second motor is fixedly connected to one end of the drive screw 431. The second motor controls the rotation of the drive screw 431, causing the drive seats 432 to move horizontally. During the horizontal movement of the drive seats 432, their tapered surfaces roll against the corresponding guide wheels, forcing the guide wheels to push the slide 41 towards the inner port of the corresponding threaded hole 12.

[0036] In practice, after the workers place the ground pile tube 11 onto the surface of the positioning post 2, they need to roughly align the single row of threaded holes 12 on the ground pile tube 11 with the sliding holes 6 on the positioning post 2. Then, the motor 2 controls the drive screw 431 to rotate, driving the drive seat 432 to move horizontally. This moves the guide block 421 and guide block 422 on the slide seat 41 toward the inner port of the corresponding threaded hole 12 on the ground pile tube 11. Finally, the two guide blocks 421 and two guide blocks 422 in the same alignment component 42 abut against the inner wall of the inner port of the same threaded hole 12 at different positions. This aligns the ground pile tube 11 relative to the positioning post 2 in a predetermined posture and fixes the ground pile tube 11 on the positioning post 2, allowing it to be rotated and repositioned by the motor 1 in conjunction with the gear set.

[0037] See Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 7The second positioning and locking mechanism 5 includes a storage cylinder 51 connected to an external mobile device and open at the lower end. The inside of the storage cylinder 51 is configured as a storage cavity 9 with a hexagonal cross-section. A cylindrical positioning post 52 is fixedly installed at the upper center of the storage cavity 9. The surface of the positioning post 52 has multiple sliding holes 2 extending along its length direction. The multiple sliding holes 2 are evenly distributed along the circumference of the positioning post 52. Multiple inner support locking plates 53 that can slide along its radial direction are provided on the positioning post 52. The inner support locking plates 53 are slidably connected to the corresponding sliding holes 2. Two symmetrical reset springs 2 are fixedly installed on one side of the inner support locking plate 53 near the inside of the positioning post 52. The other end of the reset spring 2 is fixedly connected to the inner wall of the positioning post 52 at a corresponding position, so as to automatically reset when the inner support locking plate 53 loses the pressure of the driving component 54. A drive assembly 54 is provided between the storage cylinder 51 and the positioning post 52. A aligning assembly 55 for aligning the nut 10 is provided between the drive assembly 54 and the storage cylinder 51.

[0038] The storage cylinder 51 can move vertically and horizontally via an external moving device. During feeding, nuts 10 are fed one by one from the lower port of the storage cylinder 51 into the storage cavity 9 inside the storage cylinder 51, stacked vertically. Each nut 10 is fitted onto the surface of the positioning post 2 52. Since the storage cavity 9 is hexagonal, the nut 10 is directly limited after entering the storage cavity 9. When the drive assembly 2 54 controls the inner support locking plate 53 to abut against the inner wall of the center hole of the nut 10 in the storage cylinder 51, the nut 10 and the positioning post 2 52 are coaxially centered and locked, and the alignment assembly 2 55 is idle at this time; when the inner support locking plate 53 is unlocked, the alignment assembly 2 55 moves simultaneously, and the nut 10 is aligned by clamping the two symmetrical plane segments around its periphery.

[0039] The second alignment and locking mechanism in this invention needs to be installed on an existing mobile device (i.e., a mobile platform) during use. Those skilled in the art should understand that any selection or change to the structure, model, or control method of the mobile device itself, as long as it can drive the fixture to complete the aforementioned movement function, should be considered to fall within the protection scope of this invention.

[0040] See Figure 2 , Figure 3 , Figure 8 and Figure 9The second drive assembly 54 includes a drive rod 541 rotatably mounted inside the second positioning post 52 via a connecting plate. Multiple polygonal cams 542 are fixedly mounted on the surface of the drive rod 541. The inner support locking plate 53 is set with an arc surface on the side near the polygonal cams 542. The polygonal cams 542 move in contact with the arc surface of the inner support locking plate 53. The upper end of the storage cylinder 51 is fixedly mounted with a motor 3 via a bracket. The upper end of the drive rod 541 moves through the upper end of the storage cylinder 51 and the upper end of the second positioning post 52 and is fixedly connected to the output shaft of the motor 3. The motor controls the rotation of the rotating rod 541, which in turn drives the polygonal cam 542 to rotate. Each of the outer convex surfaces of the polygonal cam 542 abuts against the arc surface of the corresponding inner support locking plate 53, thereby pushing the inner support locking plate 53 to move outward from the positioning post 2 52. Multiple inner support locking plates 53 move outward simultaneously to abut against the inner wall of the center hole of all nuts 10 sleeved on the surface of the positioning post 2 52, thereby locking all nuts 10 in the center inside the storage cylinder 51.

[0041] See Figures 2-5 The second alignment component 55 includes two swing rods 551 rotatably disposed on the outside of the storage cylinder 51 and symmetrical about the center of the storage cylinder 51. The lower end of the swing rod 551 is configured as a curved section and is fixedly connected to a push rod 552. The push rod 552 is perpendicular to the swing rod 551. Two guide seats 553 are fixedly disposed on the outside of the storage cylinder 51. The guide seats 553 are provided with strip-shaped guide holes. The upper end of the swing rod 551 is slidably disposed in the corresponding strip-shaped guide hole. The upper end of the drive rotating rod 541 is fixedly disposed with a drive disk 554. Two push-pull plates 555 are hinged to the surface edge of the drive disk 554. The end of the push-pull plate 555 away from the drive disk 554 is hinged to the upper end of the corresponding swing rod 551. When the motor controls the drive lever 541 to rotate in the reverse direction, causing the polygonal cam 542 to abut against the corresponding inner support locking plate 53 and lock the corresponding nut 10, the drive lever 541 simultaneously drives the drive disc 554 to rotate. This causes the drive disc 554 to pull the swing rod 551 to rotate via the push-pull plate 555, causing the originally horizontal push rod 552 to swing away from the positioning post 52. Figure 9 As shown; when the motor controls the drive rod 541 to rotate forward, it drives the polygonal cam 542 to rotate forward, causing the inner support locking plate 53 to release the lock on the nut 10. At this time, the swing rod 551 rotates, causing the push rod 552 to move towards the positioning post 52 and finally abut against the corresponding horizontal section of the circumference of the nut 10. The two push rods 552 simultaneously abut against the two relatively symmetrical horizontal sections of the circumference of the nut 10, thereby straightening the nut 10. Figure 3 As shown.

[0042] It should be noted that the rotation angle of the drive disc 554 and the swing distance of the swing rod 551 driving the push rod 552 have been repeatedly tested by personnel in this technical field to ensure that when the drive rod 541 drives the drive disc 554 to rotate, the drive disc 554 can drive the swing rod 551 and the push rod 552 to move accordingly to straighten the nut 10 through the push-pull plate 555.

[0043] In actual operation, the nut 10 inside the storage cylinder 51 is locked by the various inner support locking plates 53 on multiple directions around the second positioning post 52. At this time, the push rod 552 moves away from the second positioning post 52. When the various inner support locking plates 53 on the second positioning post 52 retract inwards simultaneously, the push rod 552 moves inwards towards the second positioning post 52, which is used to align the nut 10 placed on the surface of the ground pile pipe 11. Figure 3 As shown.

[0044] The process of using the fixture in this solution in conjunction with external welding equipment is as follows: The worker places the end of the ground pile pipe 11 that needs to be welded with the nut 10 onto the surface of the positioning post 2, and then roughly aligns any row of threaded holes 12 on the surface of the ground pile pipe 11 along its length with the corresponding sliding hole 6 on the surface of the positioning post 2. Then, the motor 2 controls the drive seat 432 to cooperate with the slide seat 41, so that the guide block 1 421 and guide block 2 422 at all positions move toward the inner wall of the corresponding threaded hole 12. The inclined section of the guide block 1 421 and guide block 2 422 is used to align the threaded hole 12 with the corresponding sliding hole 6. The pressure generated during the alignment process can lock the ground pile pipe 11 and the positioning post 2 relative to each other.

[0045] For ease of understanding, the welding direction in this scheme is from right to left. Under the control of the external mobile device, the storage cylinder 51 moves downward to above the first threaded hole 12 on the far right of the ground pile pipe 11. Then, the inner support locking plate 53 on the periphery of the positioning column 2 52 retracts simultaneously, causing all the nuts 10 fixed in the storage cylinder 51 to move downward simultaneously until the lowest nut 10 falls to the outer port position of the corresponding threaded hole 12 on the upper surface of the ground pile pipe 11 under the guidance of the inner support locking plate 53. At this time, there is still a certain distance between the push rod 552 and the nut 10. Then, drive the rotating rod 541 to rotate further in the forward direction, and the inner support locking plate 53 to retract further towards the center of the second positioning post 52, so that the swing rod 551 moves further towards the horizontal section around the nut 10. The two push rods 552 finally collide and clamp with the two horizontal sections symmetrical around the nut 10, straightening the nut 10. Then drive the rotating rod 541 to rotate in the reverse direction by a certain angle, so that the inner support locking plate 53 moves outward towards the second positioning post 52 to lock the straightened nut 10 in the center. Then, the external welding gun is aimed at the connection between the straightened and locked nut 10 and the ground pile pipe 11, and rotates and welds with the center of the second positioning post 52 as the center.

[0046] After the nut 10 in a single position is welded, the inner support locking plate 53 separates from the welded nut 10. Then, the storage cylinder 51 moves the inner support locking plate 53 upwards by a certain height, so that the lower end of the inner support locking plate 53 is inside the second nut 10. Then, the inner support locking plate 53 expands outwards again to fix the other nuts 10 inside the storage cylinder 51. Then, the storage cylinder 51 moves to the left as a whole to the upper end of the next threaded hole 12 on the ground pile pipe 11, and the welding operation is repeated.

[0047] After all the threaded holes 12 on the ground pile pipe 11 have been welded, the positioning column 2 is controlled by the motor and gear set to rotate the ground pile pipe 11 by 90°, and the welding operation is repeated. This cycle is repeated to complete the welding of nuts 10 on all the threaded holes 12 on the ground pile pipe 11.

[0048] The ground pile pipe 11 is automatically locked by the alignment and locking mechanism 4. Workers only need to roughly align the threaded hole 12 of the ground pile pipe 11 with the sliding hole 6 of the positioning post 2. The drive component 43 then drives the slide block 41 to move the alignment component 42 outwards. The threaded hole 12 is finely aligned using the different inclinations of the guide blocks 421 and 422. Finally, the ground pile pipe 11 and the positioning post 2 are locked relative to each other through the combined pressure of multiple alignment components 42. This eliminates the need for repeated manual calibration and solves the problem of time-consuming manual adjustment of the threaded hole 12 of the ground pile pipe 11 and the tendency for positioning misalignment in existing technologies. In the alignment and locking mechanism 5, the nut 10 is initially limited by the hexagonal storage cavity 9 of the storage cylinder 51. The inner support locking plate 53 can first center and lock the nut 10 inside the storage cylinder 51. When discharging material, the inner support locking plate 53 retracts, causing the nut 10 to be in the guide... The nut 10 is precisely lowered to the threaded hole 12. Then, the alignment component 2 55 completes the alignment by clamping the two symmetrical horizontal sections of the nut 10. Finally, the inner support locking plate 53 expands outward again to achieve centering and locking, realizing fully automatic feeding, guiding, alignment, and locking of the nut 10. This replaces manual operation and solves the quality problems of high labor intensity, low efficiency, and easy alignment deviation associated with manual placement of the nut 10. Through the cooperation of the rotating mechanism 3 and the alignment and locking mechanism 4, after the welding of one row of threaded holes 12, the driving positioning column 2 drives the ground pile pipe 11 to rotate precisely 90°. Then, the feeding, locking, and welding process of the nut 10 is repeated, realizing the cyclic processing of multiple rows of threaded holes 12. This achieves automated continuous welding of multiple rows of threaded holes 12 on the ground pile pipe 11, solving the problems of multiple manual adjustments to the pipe posture and cumbersome, low-efficiency processes required for welding multiple rows of threaded holes 12. In summary, the coordinated operation of each mechanism in this solution improves the degree of automation, reduces manual intervention, ensures welding stability, and improves welding quality.
