[0035] During the specific implementation process, it can be as Figure 1As shown, the rotating frame 1 is supported by a gantry, and the flipping of the rotating frame 1 is realized by a rotating motor 7 on the gantry. The rotating frame 1 can be set as a rectangle, and the rotating frame 1 is formed by connecting two transverse frame arms and two longitudinal frame arms. The extending direction of the transverse frame arms is consistent with the length direction of the rotating frame 1, and the extending direction of the longitudinal frame arms is consistent with the width direction of the rotating frame 1. The transverse frame arms are the frame arms 11 where the second telescopic clamping member 3 is located in Figure 1 . The longitudinal frame arms are the frame arms where the first telescopic clamping member 2 is located in Figure 1 . The extending direction of the support beam 4 corresponding to the width direction of the rotating frame 1 means that both ends of the support beam 4 are connected to the transverse frame arms.

At the same time, the opening can be strip-shaped and extend along the moving direction of the second cross plate 53 as a whole. Figure 1 the frame arms where the second telescopic clamping member 3 is located in Figure 1 , and the longitudinal frame arms are the frame arms where the first telescopic clamping member 2 is located in Figure 1 . The extending direction of the support beam 4 corresponding to the width direction of the rotating frame 1 means that both ends of the support beam 4 are connected to the transverse frame arms. The number of support beams 4 is not limited in this embodiment. The number of the second telescopic clamping members 3 can be the same as the number of the support beams 4. The number of the fixing members 5 is also not limited, and the stability of the longitudinal pipe movement and positioning can be achieved through multiple fixing members 5. The driving motor can be installed on the inner side wall of the first cross plate 52. An opening is provided on the second cross plate 53. The output shaft of the driving motor passes through the opening and is connected to the incomplete gear 56. At the same time, the opening can be strip-shaped and extend along the moving direction of the second cross plate 53 as a whole. Figure 1 the frame arms where the first telescopic clamping member 2 is located in Figure 1 . The extending direction of the support beam 4 corresponding to the width direction of the rotating frame 1 means that both ends of the support beam 4 are connected to the transverse frame arms. The number of support beams 4 is not limited in this embodiment. The number of the second telescopic clamping members 3 can be the same as the number of the support beams 4. The number of the fixing members 5 is also not limited, and the stability of the longitudinal pipe movement and positioning can be achieved through multiple fixing members 5. The driving motor can be installed on the inner side wall of the first cross plate 52. An opening is provided on the second cross plate 53. The output shaft of the driving motor passes through the opening and is connected to the incomplete gear 56. At the same time, the opening can be strip-shaped and extend along the moving direction of the second cross plate 53 as a whole. The extending direction of the support beam 4 corresponding to the width direction of the rotating frame 1 means that both ends of the support beam 4 are connected to the transverse frame arms. The number of support beams 4 is not limited in this embodiment. The number of the second telescopic clamping members 3 can be the same as the number of the support beams 4. The number of the fixing members 5 is also not limited, and the stability of the longitudinal pipe movement and positioning can be achieved through multiple fixing members 5. The driving motor can be installed on the inner side wall of the first cross plate 52. An opening is provided on the second cross plate 53. The output shaft of the driving motor passes through the opening and is connected to the incomplete gear 56. At the same time, the opening can be strip-shaped and extend along the moving direction of the second cross plate 53 as a whole.

[0036] During the operation, the support beam 4 can be slid so that the support beam 4 reaches the welding position of the longitudinal pipe. Then, the transverse pipe is placed at the preset position of the rotating frame 1 through the robotic arm. Then, the first telescopic clamping member 2 is slid so that the first telescopic clamping member 2 is aligned with the end of the transverse pipe. Then, the transverse pipe is clamped and positioned by the left and right first telescopic clamping members 2. At this time, the support beam 4 is located below the transverse pipe to support the transverse pipe. Then, the longitudinal pipe is placed on the support beam 4 through the robotic arm. The second telescopic clamping member 3 is moved to align it with the end of the longitudinal pipe. Then, the second telescopic clamping member 3 is started, and the longitudinal pipe is pushed by the second telescopic clamping member 3 until it abuts against the transverse pipe. Then, the second telescopic clamping member 3 is retracted, and the fixing member 5 is started, such as Figure 3 . Figure 3As shown in the figure, the driving motor drives the incomplete gear 56 to rotate. Initially, the incomplete gear 56 meshes with the first rack 54. By driving the first rack 54, the second cross plate 53 is driven to move into the groove of the first cross plate 52, so that the fixing plate 57 abuts against the side wall of the longitudinal pipe. Then, the longitudinal pipe is pushed to abut against the vertical plate 51. The incomplete gear 56 continues to rotate. At this time, the incomplete gear 56 meshes with the second rack 55. By driving the second rack 55, the second cross plate 53 moves out of the groove. Then, the fixing plate 57 moves away from the longitudinal pipe. At this time, the second telescopic clamping member 3 is started again to ensure the abutment of the longitudinal pipe and the transverse pipe and realize the positioning of the longitudinal pipe through the limitation of the second telescopic clamping member 3. Finally, the incomplete gear 56 rotates again in the original direction, so as to mesh with the first rack 54 again, and the fixing plate 57 is driven to abut against the side wall of the longitudinal pipe through the first rack 54, realizing clamping and further improving the positioning stability of the longitudinal pipe. At this time, start the automatic welding robot and weld at the abutting position of the longitudinal pipe and the transverse pipe.

[0037] The second telescopic clamping member 3 has two positioning operations. The first positioning operation can reduce the deviation of the position of the longitudinal pipe after the fixing member 5 pushes the longitudinal pipe, so as to facilitate the second positioning operation and improve the accuracy of the second positioning operation.

[0038] The retraction operation of the fixing plate 57 after pushing the longitudinal pipe can avoid the obstruction of the fixing plate 57 to the operation of the second telescopic clamping member 3 pushing the longitudinal pipe. In addition, the longitudinal pipe is first pushed to abut against the vertical plate 51, and the stress is shared by the vertical plate 51, which can reduce the force on the second telescopic clamping member 3 when the fixing plate 57 abuts against the longitudinal pipe again.

[0039] Embodiment 2

[0040] In order to simply realize the support and positioning of the pipe after the rotary frame 1 is turned over, improvements are made on the basis of Embodiment 1, as Figure 1 shown. In this embodiment, at least two of the fixing members 5 are arranged on one support beam 4, and the two fixing members 5 are arranged on two opposite side walls of the support beam 4. An expansion rod is provided on one side of the vertical plate 51 close to the support beam 4, and the expansion rod is slidably connected to the side wall of the support beam 4.

[0041] In the specific implementation process, after the welding operation on the front side of the abutting part of the longitudinal pipe and the transverse pipe is completed, the rotating frame 1 is flipped so as to continue the welding on the reverse side of the abutting part. After the rotating frame 1 is flipped, the longitudinal pipe is supported by the first cross plate 52 or the second cross plate 53, reducing the force on the second telescopic clamping member 3. However, the support beam 4 will block the welding position. Therefore, it is necessary to move the support beam 4 away. At this time, first, the vertical plate 51 is moved away from the support beam 4 through the telescopic rod so that the gap between the vertical plate 51 and the support beam 4 is sufficient to accommodate the longitudinal pipe. Then, the second telescopic clamping member 3 is retracted and the first telescopic clamping member 2 and the fixing member 5 are activated. The first telescopic clamping member 2 and the fixing member 5 push the frame formed after partial welding of the transverse pipe and the longitudinal pipe to move as a whole, so that the longitudinal pipe is located in the gap between the vertical plate 51 and the support beam 4, avoiding the support beam 4 from blocking the longitudinal pipe. The two fixing members 5 can improve the support stability of the longitudinal pipe. The two fixing members 5 are arranged oppositely on the two side walls of the support beam 4 as shown in Figure 1 can realize the adjustment of the longitudinal pipe in the left and right directions, and at the same time position the two sides of the longitudinal pipe simultaneously, with higher positioning stability.

[0042] Embodiment 3

[0043] In order to reduce the force on the first telescopic clamping member 2 after the rotating frame 1 is flipped, an improvement is made on the basis of Embodiment 1. As shown in Figure 1 , in this embodiment, the fixing member 5 is slidably connected to the outer side wall of the rotating frame 1 away from the second telescopic clamping member 3.

[0044] In the specific implementation process, if the transverse pipe is directly supported by the first telescopic clamping member 2 after the rotating frame 1 is flipped, the service life of the first telescopic clamping member 2 will be reduced. Therefore, in this embodiment, the fixing member 5 is also arranged on the transverse frame arm of the rotating frame 1. The transverse pipe can be supported by the first cross plate 52 or the second cross plate 53 on the fixing member 5, and the telescopic structure formed by the cooperation of the first cross plate 52 and the second cross plate 53 can adapt to the transverse pipes at different positions. Therefore, the structure of the fixing member 5 in this embodiment not only realizes the positioning of the longitudinal pipe but also realizes the support of the longitudinal pipe at different positions. The number of the fixing members 5 on the transverse frame arm is not limited in this embodiment. In order to improve the support stability of the transverse pipe, multiple fixing members 5 can be arranged on the transverse frame arm.

[0045] Embodiment 4

[0046] In order to further improve the adaptability of the fixing member 5 to the position of the transverse pipe, an improvement is made on the basis of Embodiment 3. In this embodiment, the second cross plate 53 of the fixing member 5 on the rotating frame 1 can extend to the inner wall of the rotating frame 1 on the same side as the second telescopic clamping member 3 under the drive of the incomplete gear 56.

[0047] In the specific implementation process, although the fixing members 5 on the support beam 4 and the fixing members 5 on the transverse frame arms have the same structure, since the second transverse plate 53 of the fixing member 5 on the support beam 4 needs to move a shorter distance, the lengths of its first transverse plate 52 and second transverse plate 53 are less than those of the first transverse plate 52 and second transverse plate 53 of the fixing member 5 on the transverse frame arms, and the maximum telescopic length of the corresponding second transverse plate 53 of the transverse frame arms can be set according to the length of the longitudinal frame arms.

[0048] Embodiment 5

[0049] In order to simply realize the clamping and positioning of the transverse pipe, improvements are made on the basis of Embodiments 1-4, as Figure 1 and Figure 6 shown. In this embodiment, the first telescopic clamping member 2 includes: a moving plate 21, which is slidably connected to the inner wall of the rotating frame 1; a mounting plate 22, which is connected to the top wall of the moving plate 21; a telescopic cylinder 23, which is arranged on the mounting plate 22; a docking member 24, the output shaft of the telescopic cylinder 23 is connected to the docking member 24, at least a part of the docking member 24 is used to extend into the inner hole of the pipe, and at least a part of the docking member 24 is used to abut against the end wall of the pipe.

[0050] In the specific implementation process, the docking member 24 can be set as a cone as Figure 6 shown. Utilizing the characteristics of the hollow structure of the pipe, the top of the conical docking member 24 is inserted into the inner hole of the pipe to realize the clamping and positioning of the pipe. If the moving plate 21 is slidably connected to the outer wall of the rotating frame 1, the output shaft of the rotating motor 7 will hinder the movement of the first telescopic clamping member 2, so in this embodiment, the moving plate 21 is slidably connected to the inner wall of the rotating frame 1. The telescopic cylinder 23 can be installed on the mounting plate 22 by bolts or screws.

[0051] Embodiment 6

[0052] In order to simply realize the positioning operation of the second telescopic clamping member 3 on the longitudinal pipe, improvements are made on the basis of Embodiment 5. In this embodiment, the structure of the second telescopic clamping member 3 is the same as that of the first telescopic clamping member 2.

[0053] In the specific implementation process, the structure of the second telescopic clamping member 3 is the same as that of the first telescopic clamping member 2, but the functions are different. In addition to clamping and positioning, the second telescopic clamping member 3 also has the function of pushing the longitudinal pipe. In addition, the second telescopic clamping member 3 is slidably connected to the outer side wall of the transverse frame arm to prevent the support beam 4 from hindering the movement of the second telescopic clamping member 3.

[0054] Embodiment 7

[0055] In order to simply realize that there is no relative displacement between the second telescopic clamping member 3 and the support beam 4, improvements are made on the basis of Embodiment 6, asFigures 4-5 As shown, in this embodiment, the frame arm 11 of the rotating frame 1 connected to the second telescopic clamping member 3 includes an upper plate 111 and a lower plate 112. There is a gap between the upper plate 111 and the lower plate 112, and at least one of the bottom wall of the upper plate 111 and the top wall of the lower plate 112 is provided with a slide rail 113; the welding rotation tooling further includes: a connecting rod 6, the support beam 4 is connected to the vertical plate 51 through the connecting rod 6, and the connecting rod 6 penetrates through the gap; a slider 61, and the side wall of the connecting rod 6 is provided with a slider 61 that cooperates with the slide rail 113.

[0056] During the specific implementation process, both ends of the upper plate 111 and both ends of the lower plate 112 are connected to the longitudinal frame arms. Since the longitudinal pipe is placed on the support beam 4, and the second telescopic clamping member 3 needs to push and position the longitudinal pipe, the docking member 24 of the second telescopic clamping member 3 needs to be aligned with the end of the support beam 4. In order to ensure that the second telescopic clamping member 3 is always aligned with the end of the support beam 4 during the movement of the support beam 4, in this embodiment, the transverse frame arm is set as a two-layer structure composed of the upper plate 111 and the lower plate 112, and then the connecting rod 6 is used to connect the support beam 4 and the second telescopic clamping member 3 into one body through the gap between the upper plate 111 and the lower plate 112, and then by driving the slider 61 on the connecting rod 6 to slide on the slide rail 113, the synchronous movement of the support beam 4 and the second telescopic clamping member 3 is realized. As shown in Figure 5 That is, the slide rail 113 is provided on the bottom wall of the upper plate 111, and the slide rail 113 is also provided on the top wall of the lower plate 112, and a slider 61 that is slidably connected to the two slide rails 113 is provided on the connecting rod 6.

[0057] Embodiment 8

[0058] In order to improve the welding efficiency of the automatic welding robot, this embodiment provides a method for using the welding rotation tooling. One welding rotation tooling is provided on each side of an automatic welding robot. When the automatic welding robot performs welding operations on one side of the welding rotation tooling, the other welding rotation tooling performs the clamping operation of the pipe.

[0059] During the specific implementation process, as shown in Figure 7 For each automatic welding robot, two welding rotation toolings are configured. The automatic welding robot is located between the two welding rotation toolings. Figure 7 The automatic welding robot is not shown in the figure. Since the pipe needs to be placed and positioned before welding, if a large amount of welding time is wasted waiting for the pipe to be placed and positioned after welding one product, so this embodiment provides two welding rotation toolings. When one of them is performing the placement and positioning of the pipe, the automatic welding robot welds the pipe on the other welding rotation tooling, which can greatly improve the welding efficiency.

[0060] A large number of sliding connections are mentioned in Embodiments 1-8. The structure of the sliding connection is prior art and can be achieved through a slide rail and a slider. The movement of the slider can be driven by a screw rod, a gear drive, a belt drive, a pneumatic drive, etc., all of which are prior art and will not be elaborated in this case.

[0061] Embodiment 9

[0062] In order to reduce the usage amount of the rotating motor 7 and lower the economic cost, improvements are made on the basis of Embodiment 8. As Figure 8 shown, in this embodiment, a driving gear 8 is connected to the side wall of the rotating frame 1 of a welding rotating tooling, and a driven gear 9 is connected to the side wall of the rotating frame 1 of another welding rotating tooling. The driving gear 8 is in transmission connection with the driven gear 9 through a chain 10; the rotating frame 1 is flipped by driving the driving gear 8 to rotate through the rotating motor 7; the driving gear 8 drives the driven gear 9 to rotate through the chain 10, so as to realize the flipping of the other rotating frame 1.

[0063] In the specific implementation process, in this embodiment, through the sprocket transmission method, the flipping of two rotating frames 1 is simultaneously driven by one rotating motor 7. The rotating motor 7 drives the driving gear 8 to rotate, the driving gear 8 drives the chain 10 to move, and the chain 10 drives the driven gear 9 to rotate.

[0064] Embodiment 10

[0065] In this embodiment, it includes: a fixing method for the fixing member 5, and the fixing method includes:
