[0047] The present application provides a pairing device, a welding production line applicable to the pairing device, and a welding method applicable to the welding production line.

[0048] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0049] like Figure 1-Figure 5 As shown, an embodiment of the present application provides a pairing device for pairing a rotating shaft assembly and a steel bar, comprising a first clamping member 11, a first transmission member 12, a second transmission member 13 and a force member 14. The first clamping member 11 comprises at least two first clamping parts, which are used to clamp and fix the rotating shaft assembly on both axial sides of the rotating shaft assembly; the first transmission member 12 is arranged between the at least two first clamping parts, and can drive the steel bar to approach the rotating shaft assembly clamped by the first clamping member 11 in a first direction; the second transmission member 13 is arranged between the at least two first clamping parts, and can drive the steel bar located on the first transmission member 12 to approach the rotating shaft assembly clamped by the first clamping member 11 in a second direction; the force member 14 comprises at least two force members, and at least two force members act on both ends of the steel bar located on the second transmission member 13, so that the two ends of the steel bar abut against the rotating shaft assembly.

[0050] Specifically, the handling device 4 installs the rotating shaft assembly on the first clamping member 11, and at least two first clamping parts respectively clamp the two ends of the rotating shaft assembly to fix the rotating shaft assembly; then the first transmission member 12 arranged between the at least two first clamping parts drives the steel bars to be paired to approach the rotating shaft assembly along the first direction, so that the steel bars reach the preset position in the first direction; the second transmission member 13 drives the steel bars that have reached the preset position along the first direction to move along the second direction, so that the steel bars reach the preset position in the second direction; then the force-applying part of the force-applying member 14 acts on the two ends of the steel bars that have reached the preset positions in both the first direction and the second direction, and applies a force to the two ends of the steel bars to approach the rotating shaft assembly, so that the steel bars abut against the rotating shaft assembly, thereby achieving pairing of the rotating shaft assembly and the steel bars. After the above-mentioned rotating shaft assembly and steel bars are paired, the welding device 5 welds the abutment position of the steel bars and the rotating shaft assembly, then rotates the rotating shaft assembly clamped by the first clamping member 11, repeats the above process, and the welding device 5 welds the paired steel bars and the rotating shaft assembly again until the welding of the steel bar roller 77 is completed.

[0051] Exemplarily, the first clamping part can be a locking structure such as a clamping claw that can clamp the shaft of the rotating shaft assembly; the first transmission member 12 can be a structure such as a cylinder, a hydraulic cylinder, a transmission belt or a manipulator that drives the steel bars to move; the second transmission member 13 can also be a structure such as a cylinder, a hydraulic cylinder, a transmission belt or a manipulator that drives the steel bars to move; the force-applying part can be a structure such as a cylinder or a hydraulic cylinder.

[0052] It should be noted that the axial direction of the shaft assembly refers to Figure 1 In the direction indicated by the double-headed arrow C; illustratively, the first direction refers to Figure 1 The direction indicated by the arrow D in the middle, the second direction refers to Figure 1 The direction indicated by arrow E.

[0053] The pairing device 1 of the above structure realizes the clamping and fixing of the rotating shaft assembly by setting the first clamping member 11, and then acts on the steel bar by setting the first transmission member 12, the second transmission member 13 and the force member 14 to bend the steel bar to achieve pairing with the rotating shaft assembly. Then the welding device 5 welds the paired steel bar roller 7, thereby improving the pairing efficiency of the rotating shaft assembly and the steel bar, reducing the labor intensity of the operator, improving the welding quality in the subsequent welding process, improving production efficiency, reducing welding costs, and improving safety during the pairing process.

[0054] Exemplarily, after the rotating shaft assembly and the welding of a certain steel bar are completed, the first clamping member 11 releases the clamping of the above-mentioned components, rotates the above-mentioned components, and the first clamping member 11 re-clamps the above-mentioned components. Then the first transmission member 12, the second transmission member 13 and the force member 14 act on the steel bar again for subsequent pairing and welding. Such an arrangement can also realize the pairing with multiple steel bars in the circumferential direction of the rotating shaft assembly.

[0055] Furthermore, in some embodiments, the pairing device 1 also includes a rotating member 15 connected to the first clamping member 11, and the rotating member 15 can rotate the shaft assembly clamped by the first clamping member 11. In this way, after the pairing and welding of the shaft assembly and a certain steel bar are completed, the rotating member 15 drives the first clamping member 11 clamping the shaft assembly to rotate together, and then the first transmission member 12, the second transmission member 13 and the force member 14 act on the steel bar again to perform subsequent pairing and welding of other positions to be welded between the steel bar and the shaft assembly. In this way, the pairing efficiency of the pairing device 1 for the shaft assembly and the steel bar can be further improved, the labor intensity of the operator can be further reduced, and the production efficiency can be further improved.

[0056] Preferably, the number of the rotating members 15 is the same as the number of the first clamping parts, and the rotating members 15 are connected to the first clamping members 11 in a one-to-one correspondence to improve the stability of the rotating shaft assembly during rotation.

[0057] In some embodiments, the assembly device 1 also includes a first movable member 16 connected to the force member 14, and the first movable member 16 can drive the force member 14 to move along the third direction. Since in the axial direction of the shaft assembly, shaft assemblies of different sizes need to be assembled and welded with steel bars of different sizes, when the assembly device 1 assembles shaft assemblies and steel bars of different sizes, the abutment positions of the steel bars and the shaft assembly are different. Here, the first movable member 16 connected to the force member 14 is provided, so that the force position of the force member 14 on the steel bar can be conveniently adjusted, and the abutment position of the steel bar and the shaft assembly can be more tightly abutted, so as to facilitate the subsequent welding device 5 to weld the shaft assembly and the steel bar, improve the welding effect of the shaft assembly and the steel bar, improve the stability of the connection between the shaft assembly and the steel bar, and make the connection more firmly.

[0058] Exemplarily, the third direction may be the same direction as the axial direction of the rotating shaft assembly, that is, Figure 1 Of course, the third direction and the axial direction of the rotating shaft assembly may also be different, as long as the sub-motion along the axial direction of the rotating shaft assembly can be generated by moving along the third direction.

[0059] In some embodiments, the assembly device 1 further includes a frame 17 and a second moving member 18, wherein the first transmission member 12, the second transmission member 13 and the force member 14 of the frame 17 are all arranged on the frame 17; the second moving member 18 is connected to the frame 17 and can drive the frame 17 to move along the fourth direction. Since the diameters of the support plates of the rotating shaft assemblies of different sizes are different in the radial direction of the rotating shaft assembly, the positions of the steel bars to be assembled are different, which results in different abutment positions of the steel bars and the rotating shaft assembly when the assembly device 1 assembles the rotating shaft assemblies and steel bars of different sizes. Here, through the above-mentioned setting, the position of the steel bars can be conveniently adjusted, and the assembly device 1 can be used to assemble the rotating shaft assemblies and steel bars of different models, thereby improving the applicability of the assembly device 1 to assembling the rotating shaft assemblies and steel bars of different models, and also improving the forming effect of the assembly and welding of the rotating shaft assemblies and steel bars.

[0060] Exemplarily, the fourth direction is the same as the first direction, both of which are Figure 1 The direction indicated by the arrow D. Of course, the fourth direction and the first direction may also be different, as long as the sub-movement along the first direction can be generated by moving along the fourth direction.

[0061] In some embodiments, the first transmission member 12 is used to achieve the steel bar approaching the rotating shaft assembly in the first direction. In order to improve the transmission effect and simplify the structural layout of the assembly device 1, the first transmission member 12 is provided and located in the axial middle of the rotating shaft assembly, and the force member 14 acts on both ends of the steel bar to achieve the abutment between the steel bar and the rotating shaft assembly. Therefore, at least two second transmission members 13 are provided, and are respectively located on both sides of the first transmission member 12. Such a configuration can conveniently realize the transmission of the steel bar by the first transmission member 12 in the first direction, and realize the transmission of the steel bar in the second direction, thereby improving the assembly and welding efficiency of the steel bar and the rotating shaft assembly, and the assembly forming effect of the rotating shaft assembly and the steel bar.

[0062] In some embodiments, the first transmission member 12 includes a plurality of transmission parts 121, each transmission part 121 provides a transmission position for each steel bar. Exemplarily, the transmission part 121 is a groove for placing and clamping the steel bar. Since the steel bar is usually placed on the first transmission part 121 by the handling device 4 to realize the loading of the steel bar, by arranging a plurality of transmission parts 121 on the first transmission member 12, it is possible to realize the synchronous transmission of a plurality of steel bars, improve the transmission efficiency of the steel bars, and thus improve the efficiency of the assembly and welding of the steel bars and the rotating shaft assembly.

[0063] A welding production line includes the above-mentioned assembling device 1. Since the welding production line includes the above-mentioned assembling device 1, the beneficial effects of the welding production line brought by the assembling device 1 can be found in the above content and will not be repeated here.

[0064] The welding production line is used to realize welding of the steel bar roller 7, and the welding production line includes an upstream assembly device 2, a loading station 3, a handling device 4 and a welding device 5. The upstream assembly device 2 is used to realize the assembly of the rotating shaft and the support plate into a rotating shaft assembly; the loading station 3 provides a placement position for the components to be assembled; the handling device 4 includes a track 41 and a handling robot 42 that can move along the track 41, and the handling robot 42 can realize the transfer of the steel bar roller 7 between any two of the assembly device 1, the upstream assembly device 2 and the loading station 3; the welding device 5 includes a welding robot 52 that can move and is used to weld the rotating shaft assembly and / or the steel bar roller 7.

[0065] Specifically, when the welding production line is used to weld the steel bar roller 7, first, the handling device 4 places the multiple support plates located at the loading station 3 on the upstream assembly device 2, and fixes the multiple support plates through the upstream assembly device 2; then, the handling device 4 hoists the multiple rotating shafts located at the loading station 3 to the upstream assembly device 2 in sequence, so that the upstream assembly device 2 can assemble the rotating shafts and the support plates; then, the welding robot 52 of the welding device 5 welds the assembled rotating shaft assembly of the upstream assembly device 2; then, the handling device 4 moves the assembled and welded rotating shaft assembly to the assembly device 1, and the assembly The device 1 clamps and fixes the welded rotating shaft assembly, the handling device 4 moves the steel bars at the loading station 3 to the first transmission member 12, the first transmission member 12, the second transmission member 13 and the force member 14 cooperate to realize the pairing of the steel bars and the rotating shaft assembly (for the detailed process, see the above content), the welding device 5 welds the abutment position of the steel bars and the rotating shaft assembly, rotates the rotating shaft assembly fixed by the first clamping member 11, and repeats the above process until all the positions to be welded of the rotating shaft assembly are welded; finally, the handling device 4 unloads the welded steel bar roller 7 to complete a welding cycle of the steel bar roller 7.

[0066] It should be noted that the number of the loading station 3, the upstream assembly device 2, the assembly device 1, the welding device 5 and the handling device 4 is not limited here, and one or more of the above devices can be provided. Exemplarily, at least two welding devices 5 are provided, and at least two welding devices 5 are used to weld the rotating shaft assembly assembled by the upstream assembly device 2 and the steel bar roller 7 assembled by the assembly device 1, so as to improve the welding efficiency of the above devices and reduce the waiting time during the welding process.

[0067] The welding production line of the above structure can quickly and efficiently assemble and weld the rotating shaft and the support plate into a rotating shaft assembly, and can also quickly and efficiently assemble and weld the rotating shaft assembly and the steel bars into a steel bar roller 7. In this way, the efficiency of assembling the rotating shaft assembly and the steel bars can be greatly improved, and the labor intensity of the operator can be reduced, the welding quality of the product during the welding process can be improved, the production efficiency can be improved, the welding cost can be reduced, and the safety during the assembly and welding process can be improved.

[0068] In some embodiments, some of the assembling device 1, the upstream assembling device 2 and the loading station 3 are arranged on one side of the track 41, and the remaining devices are arranged on the other side of the track 41. Such an arrangement can shorten the moving distance of the conveying device 4 when transferring the rotating shaft, the support plate and the steel bar between any two of the assembling device 1, the upstream assembling device 2 and the loading station 3, thereby improving the moving efficiency of the conveying device 4 driving the above-mentioned rotating shaft, the support plate and the steel bar, and further improving the welding processing efficiency of the above-mentioned rotating shaft, the support plate and the steel bar in the welding production line.

[0069] Exemplarily, the loading station 3 is arranged on one side of the track 41, and the assembling device 1 and the upstream assembling device 2 are arranged on the other side of the track 41. Such an arrangement can further improve the moving efficiency of the conveying device 4 for the above-mentioned components, and can make the layout of the welding production line more streamlined and reduce the floor space occupied by the welding production line.

[0070] In some embodiments, the upstream assembly device 2 includes a second clamping member 21 and a fixing member 22. The second clamping member 21 includes at least two second clamping parts, which are used to clamp and fix the shaft on both sides of the shaft in the axial direction; the fixing member 22 is arranged between the at least two second clamping parts, and the fixing member 22 includes a plurality of fixing support disks. Such an arrangement can realize the assembly and fixation of multiple shafts and support disks, improve the fixing and welding efficiency of the above device, realize the assembly and welding of different numbers of support disks, and improve the applicability of the assembly of the shaft assembly.

[0071] In some embodiments, the upstream assembly device 2 further includes a third moving member 23 connected to at least a portion of the fixing member 22 and capable of driving at least a portion of the fixing member 22 to move axially along the rotating shaft. Specifically, taking the example of a rotating shaft assembly formed by welding three support plates and three rotating shafts, when the rotating shaft and the support plates are assembled into a rotating shaft assembly, first, the handling robot 42 moves the support plate on the left side of the rotating shaft assembly to the left side fixing member 22 of the upstream assembling device 2 and fixes it, then moves the right support plate to the right side fixing member 22 of the upstream assembling device 2 and fixes it, and then moves the middle support plate to the middle fixing member 22 and fixes it; then, the handling robot 42 moves the left rotating shaft to the left side second clamping member 21 of the upstream assembling device 2 and clamps it, and the handling robot 42 moves the right rotating shaft to the right side second clamping member 21 of the upstream assembling device 2 and clamps it; then, the handling robot 42 moves the middle rotating shaft to the middle position of the upstream assembling device 2, and the second clamping member 21 drives the left and right rotating shafts to move so that the three rotating shafts are docked. At this time, the third moving member 23 drives the fixing member 22 to adjust the positions of the three support plates to complete the assembly of the rotating shaft assembly. Such an arrangement can realize the pairing of a variety of different types of shaft assemblies, thereby improving the applicability of the pairing of the shaft assemblies.

[0072] For example, the axial direction of the rotating shaft is Figure 4 The direction is indicated by the double-headed arrow F.

[0073] In some embodiments, the handling robot 42 includes a robot gripper 421 and a handling body 422. The robot gripper 421 can grip the rotating shaft, the support plate and the steel bar; the handling body 422 is connected to the robot gripper 421 and can drive the robot gripper 421 to move along the track 41. Here, by providing the handling body 422 that moves along the track 41, the robot gripper 421 can conveniently move along the track 41 after gripping the above-mentioned object to be gripped, thereby improving the moving efficiency of the object to be gripped.

[0074] In some embodiments, the welding device 5 includes a bracket 51 and a welding robot 52 disposed on the bracket 51, the welding robot 52 includes a robot welding gun 521 and a robot body 522, the robot welding gun 521 is used to realize the welding of the rotating shaft assembly and the steel roller 7; the robot body 522 is connected to the robot welding gun 521, and can drive the robot welding gun 521 to move in at least two directions. Exemplarily, the robot body 522 includes at least one moving structure and / or at least one rotating structure, and the robot body 522 drives the robot welding gun 521 to move and / or rotate through at least one moving structure and / or at least one rotating structure, so as to efficiently realize the welding of the rotating shaft assembly and the steel roller 7 to be welded. Here, the robot body 522 is connected to the robot welding gun 521 to drive the robot welding gun 521 to move in at least two directions, so as to achieve the welding efficiency of the rotating shaft assembly and the steel roller 7 to be welded.

[0075] In some embodiments, the plate welding production line further includes a positioning device 6 disposed on the robot welding gun 521, and the positioning device 6 is used to scan the positions to be welded of the rotating shaft assembly and the steel roller 7, so as to realize the welding of the rotating shaft assembly and the steel roller 7 by the robot welding gun 521. Specifically, the positioning device 6 is connected to the robot welding gun 521, and the positioning device 6 scans the positions to be welded of the rotating shaft assembly and the steel roller 7, and the robot welding gun 521 and the positioning device 6 move synchronously to realize the welding of the positions to be welded of the rotating shaft assembly and the steel roller 7. With such a configuration, the welding robot 52 improves the welding quality of the rotating shaft assembly and the steel roller 7, and improves the welding efficiency of the rotating shaft assembly and the steel roller 7.

[0076] In some embodiments, the positioning device 6 includes a connecting frame 61, a movable part 62 and a laser 63. The connecting frame 61 is fixedly connected to the limiting surface; one end of the movable part 62 is connected to the connecting frame 61, and the other end is connected to the laser 63 for positioning of the positioning device 6, and the movable part 62 can adjust the relative position of the laser 63 and the welding robot 52.

[0077] In some embodiments, when the positioning device 6 and the welding robot 52 move to achieve welding of the rotating shaft assembly and the steel roller 7 at the welding position to be welded, the component of the positioning device 6 to achieve positioning is usually a laser 63, and the light emitted by the laser 63 coincides with the center intersection of the weld and the welding position of the welding robot 52, thereby improving the welding accuracy of the welding robot 52; however, since the robot welding gun 521 includes a connecting rod 5211, and the connection with the robot welding gun 521 is achieved through the connecting rod 5211, and the connecting rod 5211 is usually a cylindrical rod-shaped member, then in the process of the robot welding gun 521 and the laser 63 moving together, the laser 63 may be impacted by the outside world, causing the laser 63 to rotate relative to the connecting rod 5211, which causes the relative position of the laser 63 and the welding robot 52 to change, resulting in deviations in the welding positions of the rotating shaft assembly and the steel roller 7 of the welding robot 52, resulting in poor welding forming effects of the rotating shaft assembly and the steel roller 7. Based on this, a limiting surface is opened on the connecting rod 5211, and the positioning device 6 is connected to the connecting rod 5211 through the limiting surface. The positioning device 6 is connected to the connecting rod 5211 at the position of the limiting surface of the connecting rod 5211, thereby improving the stability of the connection between the positioning device 6 and the connecting rod 5211, and avoiding the relative position of the positioning device 6 and the welding robot 52 to change when the positioning device 6 is hit, thereby ensuring the forming effect of the welding robot 52 on the rotating shaft assembly and the steel bar roller 7.

[0078] It should be noted that the position of the limiting surface on the connecting rod 5211 is not limited here. For example, the limiting surface can be provided at any position on the connecting rod 5211, such as Figure 5 The limiting surface can also be set at the connection position between the connecting rod 5211 and the robot body 522, such as Figure 5 The position shown in B.

[0079] A welding method is applicable to the above-mentioned welding production line. Since the welding method is applicable to the above-mentioned welding production line, the beneficial effects of the welding method brought by the welding production line can be found in the above content and will not be repeated here.

[0080] The welding method comprises at least the following steps:

[0081] S001: The handling device 4 moves the rotating shaft and the supporting plate located at the loading station 3 to the upstream assembly device 2;

[0082] S002: The upstream assembling device 2 assembles the rotating shaft and the supporting plate into a rotating shaft assembly;

[0083] S003: The welding robot of the welding device 5 welds the rotating shaft assembly;
