Detailed implementation manners

[0031] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are some, but not all, of the embodiments of the present invention.

[0032] Embodiment 1

[0033] As shown in Figures 1-4 , a welding clamping tooling with a long service life includes: a rotating frame 1; a support beam 2, the end of the support beam 2 is slidably connected to the inner wall of the rotating frame 1, and the extending direction of the support beam 2 corresponds to the width direction of the rotating frame 1; a fixing member 3, the fixing member 3 includes: a vertical plate 31, the vertical plate 31 is slidably connected to the side wall of the support beam 2; a telescopic plate 32, the extending direction of the telescopic plate 32 is the same as the length direction of the rotating frame 1, one end of the telescopic plate 32 is connected to the top end of the vertical plate 31, and an installation groove 326 is provided at the end of the telescopic plate 32 away from the vertical plate 31; a fixing plate 33, one end of the fixing plate 33 is provided with a first shaft hole 331, a first limiting groove 3311 is provided on the side wall of the first shaft hole 331, the other end of the fixing plate 33 is provided with a second shaft hole 332, and a second limiting groove 3321 is provided on the side wall of the second shaft hole 332; a rotating shaft 4, one end of the rotating shaft 4 is rotatably connected to the side wall of the installation groove 326, and a first limiting block 41 that cooperates with the first limiting groove 3311 is provided on the side wall of the other end of the rotating shaft 4, and a space for the first limiting block 41 to move is left in the first limiting groove 3311; a fixed shaft 5, one end of the fixed shaft 5 is connected to the side wall of the installation groove 326, and a second limiting block 51 that cooperates with the second limiting groove 3321 is provided at the other end of the fixed shaft 5; when the fixing plate 33 is perpendicular to the telescopic plate 32, there is a gap between the first limiting block 41 and the side wall of the first limiting groove 3311, and the second limiting block 51 abuts against the side wall of the second limiting groove 3321.

[0034] During the specific implementation process, as shown in Figure 1 , the rotating frame 1 is supported by a gantry, and the rotation of the rotating frame 1 is realized by a rotating motor 10 on the gantry. The rotating frame 1 can be set as a rectangle, and the rotating frame 1 is composed of two transverse frame arms and two longitudinal frame arms connected. The extending direction of the transverse frame arm is the same as the length direction of the rotating frame 1, and the extending direction of the longitudinal frame arm is the same as the width direction of the rotating frame 1. The transverse frame arm is Figure 1 the frame arm 11 where the first telescopic clamping member 8 is located in Figure 1The frame arm 11 where the second telescopic clamping member 7 is located, the extending direction of the support beam 2 corresponding to the width direction of the rotating frame 1 means that both ends of the support beam 2 are connected to the transverse frame arm. The number of support beams 2 is not limited in this embodiment, and the number of fixing members 3 on the support beam 2 is also not limited. The stability of the longitudinal pipe movement and positioning can be achieved through multiple fixing members 3. The rotation of the rotating shaft 4 can be driven by a motor, and the motor can be referred to Figure 2 as shown, and is installed on the telescopic plate 32.

[0035] During the operation process, the transverse pipe can be first placed at the preset position of the rotating frame 1 by the robotic arm, and then the support beam 2 is moved to make the support beam 2 reach the preset position. The motor drives the rotation of the rotating shaft 4, and the first limiting block 41 on the rotating shaft 4 is as Figure 3 shown and abuts against the side wall of the first limiting groove 3311. The fixing plate 33 is pushed to rotate upward by the first limiting block 41. At this time, the fixed shaft 5 does not move and there is enough moving space between the second limiting block 51 and the second limiting groove 3321 to avoid the second limiting block 51 from generating an obstruction when the fixing plate 33 rotates upward. The fixing plate 33 can be rotated to the horizontal position to make room for the operation of placing the longitudinal pipe on the support beam 2. Then, the longitudinal pipe is placed on the support beam 2 by the robotic arm, and the end of the longitudinal pipe abuts against the side wall of the transverse pipe. The rotating shaft 4 is driven to rotate again, and the fixing plate 33 can be lowered until the fixing plate 33 is vertical. When the rotating shaft 4 rotates, the fixing plate 33 will rotate downward under its own gravity. In the initial process of rotating downward, the first limiting block 41 still remains in contact with the side wall of the first limiting groove 3311 until the side wall of the second limiting groove 3321 abuts against the second limiting block 51, and the fixing plate 33 stops rotating due to the limitation of the second limiting block 51. At this time, as Figure 4 shown, the rotating shaft 4 continues to rotate, making the first limiting block 41 away from the side wall of the first limiting groove 3311, and the rotating shaft 4 is no longer in contact with the fixing plate 33. The telescopic plate 32 contracts to make the fixing plate 33 abut against the side wall of the longitudinal pipe, and pushes the longitudinal pipe to abut against the vertical plate 31, thereby realizing the clamping and positioning of the longitudinal pipe.

[0036] The length of the fixed shaft 5 can be greater than half of the width of the fixing plate 33 to improve the stability of the fixed shaft 5 when it supports the fixing plate 33 alone and avoid its deflection.

[0037] Embodiment 2

[0038] In order to further reduce the force on the rotating shaft 4, an improvement is made on the basis of Embodiment 1. As Figure 3 shown, in this embodiment, there is a gap 6 between the side wall of the rotating shaft 4 and the first shaft hole 331.

[0039] During the specific implementation process, there is no contact between the side wall of the rotating shaft 4 and the first shaft hole 331 all the time, and the rotation of the fixing plate 33 is only pushed by the first limiting block 41.Figure 3 In this state, the support of the fixed plate 33 is realized by the fixed shaft 5 and the first limiting block 41. Figure 4 In this state, the support of the fixed plate 33 is realized by the fixed shaft 5.

[0040] Embodiment 3

[0041] In order to simply realize the telescoping of the telescopic plate 32 and facilitate the secondary adjustment of the position of the longitudinal pipe, improvements are made on the basis of Embodiment 1, as Figures 5-6 shown. In this embodiment, the telescopic plate 32 includes: a first cross plate 321, one end of the first cross plate 321 is connected to the top end of the vertical plate 31, and a groove is provided at the other end of the first cross plate 321; a second cross plate 322, the second cross plate 322 is provided with an inner cavity, the outer wall of the second cross plate 322 is slidably connected to the side wall of the groove, and the end of the second cross plate 322 away from the first cross plate 321 is rotatably connected to the fixed plate 33; a first rack 54323 and a second rack 55324, opposite first rack 54323 and second rack 55324 are provided on the side wall of the inner cavity, the number of teeth of the second rack 55324 is less than that of the first rack 54323; an incomplete gear 56325, the incomplete gear 56325 is arranged between the first rack 54323 and the second rack 55324, and the incomplete gear 56325 can be meshed with the first rack 54323 or the second rack 55324; a driving motor, the driving motor is connected to the incomplete gear 56325; the welding clamping tooling further includes: a first telescopic clamping member 8, the first telescopic clamping member 8 is slidably connected to the outer wall of any one side in the width direction of the rotating frame 1, and the first telescopic clamping member 8 is used for abutting against the end of the pipe.

[0042] During the specific implementation process, the driving motor drives the incomplete gear 56325 to rotate, and the telescopic movement of the second cross plate 322 is realized through the meshing transmission between the incomplete gear 56325 and the first rack 54323 or the second rack 55324. The number of teeth of the second rack 55324 is less than that of the first rack 54323, which can realize the appropriate retraction of the fixed plate 33 and facilitate the secondary adjustment of the position of the longitudinal pipe. The driving motor can be installed on the inner side wall of the first cross plate 321, an opening is provided on the second cross plate 322, the output shaft of the driving motor passes through the opening and is connected to the incomplete gear 56325, and at the same time, the opening can be strip-shaped and extend along the moving direction of the second cross plate 322 as a whole.

[0043] During the operation process, the longitudinal pipe is placed on the support beam 2 by the robotic arm, the first telescopic clamping member 8 is moved to align it with the end of the longitudinal pipe, then the first telescopic clamping member 8 is started, and the longitudinal pipe is pushed by the first telescopic clamping member 8 until the longitudinal pipe abuts against the transverse pipe, and then the first telescopic clamping member 8 is retracted, and the fixing member 3 is started, asFigure 6 As shown in the figure, the driving motor drives the incomplete gear 56325 to rotate. Initially, the incomplete gear 56325 meshes with the first rack 54323. The first rack 54323 drives the second cross plate 322 to move into the groove of the first cross plate 321, so that the fixing plate 33 abuts against the side wall of the longitudinal pipe. Then, the longitudinal pipe is pushed to abut against the vertical plate 31. The incomplete gear 56325 continues to rotate. At this time, the incomplete gear 56325 meshes with the second rack 55324. The second rack 55324 drives the second cross plate 322 to move out of the groove. Then, the fixing plate 33 moves away from the longitudinal pipe. At this time, the first telescopic clamping member 8 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 first telescopic clamping member 8. Finally, the incomplete gear 56325 rotates again in the original direction, so as to mesh with the first rack 54323 again, and the fixing plate 33 is driven by the first rack 54323 to abut against the side wall of the longitudinal pipe, realizing clamping and further improving the positioning stability of the longitudinal pipe. At this time, start the automatic welding robot to weld at the abutting position of the longitudinal pipe and the transverse pipe.

[0044] The first telescopic clamping member 8 has two positioning operations. The first positioning operation can reduce the deviation of the position of the longitudinal pipe after the fixing member 3 pushes the longitudinal pipe, so as to facilitate the second positioning operation and improve the accuracy of the second positioning operation.

[0045] The retraction operation of the fixing plate 33 after pushing the longitudinal pipe can avoid the obstruction of the fixing plate 33 to the operation of the first telescopic clamping member 8 pushing the longitudinal pipe. In addition, the longitudinal pipe is first pushed to abut against the vertical plate 31, and the stress is shared by the vertical plate 31, which can reduce the force on the first telescopic clamping member 8 when the fixing plate 33 abuts against the longitudinal pipe again.

[0046] Embodiment 4

[0047] In order to simply realize the support and positioning of the pipe after the rotating 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 3 are arranged on one support beam 2. The two fixing members 3 are arranged on two opposite side walls of the support beam 2. One side of the vertical plate 31 close to the support beam 2 is provided with a telescopic rod 6, and the telescopic rod 6 is slidably connected to the side wall of the support beam 2.

[0048] During the specific implementation process, after the welding operation on the front side of the butt joint between the longitudinal pipe and the transverse pipe is completed, the rotating frame 1 flips to continue the welding on the reverse side of the butt joint. After the rotating frame 1 flips, the longitudinal pipe is supported by the first cross plate 321 or the second cross plate 322, reducing the force on the first telescopic clamping member 8. However, the support beam 2 will block the welding position. Therefore, it is necessary to move the support beam 2 away. At this time, first, the vertical plate 31 is moved away from the support beam 2 through the telescopic rod 6 to make the gap between the vertical plate 31 and the support beam 2 large enough to accommodate the longitudinal pipe. Then, the first telescopic clamping member 8 is retracted and the fixing member 3 is activated. The fixing member 3 pushes the overall frame formed after partial welding of the transverse pipe and the longitudinal pipe to move, so that the longitudinal pipe is located in the gap between the vertical plate 31 and the support beam 2, avoiding the support beam 2 from blocking the longitudinal pipe. The two fixing members 3 can improve the support stability of the longitudinal pipe. The two fixing members 3 are arranged oppositely on the two side walls of the support beam 2 as shown in Figure 1 to realize the adjustment of the longitudinal pipe in the left and right directions and simultaneously position both sides of the longitudinal pipe, with higher positioning stability.

[0049] Embodiment 5

[0050] In order to realize the positioning of the transverse pipe, improvements are made on the basis of Embodiments 1-4. As shown in Figure 1 and Figure 7 , in this embodiment, it further includes: a second telescopic clamping member 7. There are at least two second telescopic clamping members 7, and the two second telescopic clamping members 7 are relatively arranged on both sides in the length direction of the rotating frame 1; the second telescopic clamping member 7 is slidably connected to the rotating frame 1, and the two second telescopic clamping members 7 are used to abut against the ends of the pipe.

[0051] During the specific implementation process, after the transverse pipe is placed at the preset position of the rotating frame 1 by the robotic arm, the second telescopic clamping member 7 is moved so that the second telescopic clamping member 7 is aligned with the end of the transverse pipe. Then, the second telescopic clamping member 7 is activated, as shown in Figure 7 , to butt against both ends of the transverse pipe to achieve clamping and positioning. After the positioning of the transverse pipe is completed, the longitudinal pipe is placed and positioned.

[0052] During the movement of the pipe after the rotating frame 1 flips, the second telescopic clamping member 7 can also be used for movement to improve the movement stability.

[0053] Embodiment 6

[0054] In order to simply realize the clamping and positioning of the transverse pipe, improvements are made on the basis of Embodiment 5. As shown in Figure 1 and Figures 7-8As shown in the figure, in this embodiment, the second telescopic clamping member 7 includes: a moving plate 71, which is slidably connected to the inner wall of the rotating frame 1; a mounting plate 72, which is connected to the top wall of the moving plate 71; a telescopic cylinder 73, which is arranged on the mounting plate 72; a docking member 74, the output shaft of the telescopic cylinder 73 is connected to the docking member 74, at least a part of the docking member 74 is used to extend into the inner hole of the pipe, and at least a part of the docking member 74 is used to abut against the end wall of the pipe.

[0055] In the specific implementation process, the docking member 74 can be as Figure 7 shown and is set to be conical. Utilizing the characteristics of the hollow structure of the pipe, the top of the conical docking member 74 is inserted into the inner hole of the pipe to achieve the clamping and positioning of the pipe. If the moving plate 71 is slidably connected to the outer wall of the rotating frame 1, the output shaft of the rotating motor 10 will hinder the movement of the second telescopic clamping member 7. Therefore, in this embodiment, the moving plate 71 is slidably connected to the inner wall of the rotating frame 1. The telescopic cylinder 73 can be installed on the mounting plate 72 by bolts or screws.

[0056] Embodiment 7

[0057] In order to simply implement the positioning operation of the first telescopic clamping member 8 on the longitudinal pipe, an improvement is made on the basis of Embodiment 6. In this embodiment, the structure of the first telescopic clamping member 8 is the same as that of the second telescopic clamping member 7.

[0058] In the specific implementation process, the structure of the first telescopic clamping member 8 is the same as that of the second telescopic clamping member 7, but the functions are different. In addition to clamping and positioning, the first telescopic clamping member 8 also has the function of pushing the longitudinal pipe. In addition, the first telescopic clamping member 8 is slidably connected to the outer side wall of the transverse frame arm to prevent the support beam 2 from hindering the movement of the first telescopic clamping member 8.

[0059] Embodiment 8

[0060] In order to reduce the force on the second telescopic clamping member 7 after the rotating frame 1 flips, an improvement is made on the basis of Embodiment 5. In this embodiment, the fixing member 3 is slidably connected to the outer side wall of the rotating frame 1 away from the first telescopic clamping member 8.

[0061] In the specific implementation process, if the transverse pipe is directly supported by the second telescopic clamping member 7 after the rotating frame 1 is turned over, the service life of the second telescopic clamping member 7 will be reduced. Therefore, in this embodiment, a fixing member 3 is also provided on the transverse frame arm of the rotating frame 1, and the transverse pipe can be supported by the first transverse plate 321 or the second transverse plate 322 on the fixing member 3. The telescopic structure formed by the cooperation of the first transverse plate 321 and the second transverse plate 322 can adapt to the transverse pipes at different positions. Therefore, the structure of the fixing member 3 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 3 on the transverse frame arm is not limited in this embodiment. In order to improve the support stability of the transverse pipe, a plurality of fixing members 3 can be provided on the transverse frame arm.

[0062] Embodiment 9

[0063] In order to further improve the adaptability of the fixing member 3 to the position of the transverse pipe, an improvement is made on the basis of Embodiment 8. In this embodiment, the second transverse plate 322 of the fixing member 3 on the rotating frame 1 can extend to the inner wall of the rotating frame 1 on the same side as the first telescopic clamping member 8 under the drive of the incomplete gear 56325.

[0064] In the specific implementation process, although the fixing members 3 on the support beam 2 and the fixing members 3 on the transverse frame arm have the same structure, since the second transverse plate 322 of the fixing member 3 on the support beam 2 needs to move a shorter distance, the lengths of the first transverse plate 321 and the second transverse plate 322 are less than those of the first transverse plate 321 and the second transverse plate 322 of the fixing member 3 on the transverse frame arm. The maximum telescopic length of the corresponding second transverse plate 322 of the transverse frame arm can be set according to the length of the longitudinal frame arm.

[0065] Embodiment 10

[0066] In order to simply realize that there is no relative displacement between the first telescopic clamping member 8 and the support beam 2, an improvement is made on the basis of Embodiment 5, as Figures 8-9 shown. In this embodiment, the frame arm 11 of the rotating frame 1 connecting the first telescopic clamping member 8 includes an upper plate 111 and a lower plate 112, and there is a gap between the upper plate 111 and the lower plate 112. 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 clamping tool with a long service life further includes: a connecting rod 9, the support beam 2 is connected to the vertical plate 31 through the connecting rod 9, and the connecting rod 9 penetrates through the gap; a slider 91, and a slider 91 matching with the slide rail 113 is provided on the side wall of the connecting rod 9.

[0067] In 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 2, and the first telescopic clamping member 8 needs to push and position the longitudinal pipe, the docking member 74 of the first telescopic clamping member 8 needs to be aligned with the end of the support beam 2. In order to ensure that the first telescopic clamping member 8 is always aligned with the end of the support beam 2 during the movement of the support beam 2, 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. Then, the connecting rod 9 is used to connect the support beam 2 and the first telescopic clamping member 8 into one body through the gap between the upper plate 111 and the lower plate 112. Then, by driving the slider 91 on the connecting rod 9 to slide on the slide rail 113, the synchronous movement of the support beam 2 and the first telescopic clamping member 8 is realized. It can be as Figure 9 shown that a slide rail 113 is provided on the bottom wall of the upper plate 111, and a slide rail 113 is also provided on the top wall of the lower plate 112, and a slider 91 that is slidably connected to the two slide rails 113 is provided on the connecting rod 96.

[0068] A large number of sliding connections are mentioned in Embodiments 1-10. The structure of the sliding connection is prior art and can be realized 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.

[0069] In summary, first slide the support beam 2 so that the support beam 2 reaches the welding position of the longitudinal pipe. Then place the transverse pipe at the preset position of the rotating frame 1 through the robotic arm. Then slide the second telescopic clamping member 7 so that the second telescopic clamping member 7 aligns with the end of the transverse pipe. Then, the left and right second telescopic clamping members 7 are used to clamp and position the transverse pipe. At this time, the support beam 2 is located below the transverse pipe to support the transverse pipe. Then rotate the fixing plate 33 so that the fixing plate 33 is horizontal. Then place the longitudinal pipe on the support beam 2 through the robotic arm. Move the first telescopic clamping member 8 to align it with the end of the longitudinal pipe. Then start the first telescopic clamping member 8 and push the longitudinal pipe through the first telescopic clamping member 8 until the longitudinal pipe abuts against the transverse pipe. Then retract the first telescopic clamping member 8 and rotate the fixing plate 33 so that the fixing plate 33 is vertical. Start the telescopic plate 32, and the driving motor drives the incomplete gear 56325 to rotate. Initially, the incomplete gear 56325 meshes with the first rack 54323, and drives the second cross plate 322 to move into the groove of the first cross plate 321 through the first rack 54323, so that the fixing plate 33 abuts against the side wall of the longitudinal pipe. Then push the longitudinal pipe to abut against the vertical plate 31. The incomplete gear 56325 continues to rotate. At this time, the incomplete gear 56325 meshes with the second rack 55324, and drives the second cross plate 322 to move out of the groove through the second rack 55324. Then the fixing plate 33 moves away from the longitudinal pipe. At this time, start the first telescopic clamping member 8 again to ensure the abutment of the longitudinal pipe and the transverse pipe and through the restriction of the first telescopic clamping member 8 to realize the positioning of the longitudinal pipe. Finally, the incomplete gear 56325 rotates in the original direction again, so as to mesh with the first rack 54323 again, and drive the fixing plate 33 to abut against the side wall of the longitudinal pipe to realize clamping, further improving the positioning stability of the longitudinal pipe. At this time, start the automatic welding robot to weld on the front at the abutment position of the longitudinal pipe and the transverse pipe. After the front welding is completed, the rotating frame 1 flips. The transverse pipe is supported by the fixing member 3 on the transverse frame arm, and the longitudinal pipe is supported by the fixing member 3 on the support beam 2. At this time, first make the vertical plate 31 move away from the support beam 2 through the telescopic rod 6, so that the gap between the vertical plate 31 and the support beam 2 is sufficient to accommodate the longitudinal pipe. Then retract the first telescopic clamping member 8 and start the fixing member 3. Push the frame body formed after partial welding of the transverse pipe and the longitudinal pipe as a whole through the fixing member 3, so that the longitudinal pipe is located in the gap between the vertical plate 31 and the support beam 2, avoiding the shielding of the support beam 2 on the longitudinal pipe, and then the reverse welding can be carried out.

[0070] To improve the welding efficiency of the automatic welding robot, during the use of the welding rotating tooling, it can be as Figure 10As shown, one of the welding rotary jigs is provided on each side of an automatic welding robot. When the automatic welding robot performs welding operations on one side of the welding rotary jig, the welding rotary jig on the other side performs the clamping operation of the pipe. Two welding rotary jigs are configured for each automatic welding robot, and the automatic welding robot is located between the two welding rotary jigs. Figure 10 The automatic welding robot is not shown in Figure 10 . Since the placement and positioning of the pipe are required before welding, if the placement and positioning of the pipe are waited for after welding one product, a large amount of welding time will be wasted. Therefore, two welding rotary jigs are provided. When one of them performs the placement and positioning of the pipe, the automatic welding robot welds the pipe on the other welding rotary jig, which can greatly improve the welding efficiency.

[0071] In order to reduce the usage amount of the rotary motor 10 and lower the economic cost, as Figure 11 shown, a driving gear 101 is connected to the side wall of the rotary frame 1 of one welding rotary jig, and a driven gear 102 is connected to the side wall of the rotary frame 1 of the other welding rotary jig. The driving gear 101 is in transmission connection with the driven gear 102 through a chain 103; the rotary frame 1 is flipped by driving the driving gear 101 to rotate through the rotary motor 10; the driving gear 101 drives the driven gear 102 to rotate through the chain 103, so as to realize the flipping of the other rotary frame 1. Through the sprocket transmission method, the flipping of two rotary frames 1 is driven by one rotary motor 10 at the same time, reducing the economic cost.

[0072] The above are only the preferred embodiments of the present invention and are not used to limit the present invention. For those skilled in the art, the present invention can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
