Description

Technical Field

[0001] The present application relates to the technical field of steel welding, and in particular to a welding device for steel processing. Background Art

[0002] In modern industrial production, steel frames are widely used in various engineering construction projects, such as buildings, bridges, and mechanical equipment. The manufacturing process of steel frames usually requires welding multiple short steel bars into long steel bars, and then transporting them to the site for assembly to form steel frames. This process is crucial to improving the construction efficiency of the entire project.

[0003] Traditional welding of short steel bars relies too much on manual operation, that is, the operator needs to place two short steel bars at the welding station and align the two short steel bars end to end, then weld them with a welding gun, and take them out after welding to weld the next group of short steel bars. However, although this type of welding method is highly flexible, it has low welding efficiency and is easily affected by the operator's skills and state, resulting in obvious differences in the welding quality of each long steel bar, which is difficult to meet the needs of large-scale production. Therefore, further improvement is needed. Summary of the invention

[0006] By adopting the above technical solution, during welding, two short steels to be welded are placed on the loading station and pushed into the conveyor turntable by the loading assembly. Then, the conveyor turntable is driven to rotate by the rotating shaft to transfer the short steels to the welding station. The welding station is located on the top of the conveyor turntable, thereby raising the short steels and coordinating with the swing of the robot arm so that the welding gun can weld the steels in all directions, thereby improving the welding quality. After the welding is completed, the conveyor turntable is continued to be driven to rotate, and the long steels are transferred to the unloading station and pushed out by the unloading assembly, thereby improving the welding efficiency of the overall structure.

[0007] Optionally, the outer peripheral side of the conveying turntable has a plurality of docking grooves for steel to be embedded, and the plurality of docking grooves are arranged at intervals around the central axis of the conveying turntable, and the inner walls of the docking grooves are embedded with magnet blocks for magnetically attracting steel; a loading platform is provided on one side of the mounting frame, and the loading platform is located in the loading station; the loading assembly includes a loading push bar, a pushing cylinder and a correction alignment component, and the loading push bar is slidably installed on the loading platform, and the loading push bar has a loading area for placing short steel; the pushing cylinder is arranged on the loading platform to drive the loading push bar close to or away from the conveying turntable; the correction alignment component is arranged on the loading platform to correct and align the short steel.

[0008] By adopting the above-mentioned technical scheme, two short steel materials to be welded are placed in the loading area of ​​the loading push bar, and the two short steel materials are aligned by means of the deviation correction alignment member, and then the loading push bar is pushed toward the conveying turntable by the pushing cylinder, so that the short steel materials are embedded in the docking groove of the conveying turntable, and the magnet block in the docking groove can magnetically attract the short steel materials, thereby fixing the short steel materials on the conveying turntable, so that the conveying turntable can transfer them, thereby improving the convenience of loading the short steel materials.

[0009] Optionally, a material unloading platform is provided on one side of the mounting frame, and the material unloading platform is located in the material unloading station; the material unloading assembly includes a material unloading push bar and a connecting bar, the material unloading push bar is slidably installed on the material unloading platform, one end of the connecting bar is connected to the material unloading push bar, and the other end passes over the mounting frame and is connected to the material loading push bar, and the material loading push bar and the material unloading push bar are connected to each other by the connecting bar; when the material loading push bar pushes the short steel to be welded into the conveying turntable, the material unloading push bar pushes the welded long steel out of the conveying turntable.

[0010] By adopting the above technical solution, after the short steel is transferred to the welding station and the welding is completed, the conveyor turntable is continued to be driven to rotate to transfer the welded long steel to the unloading station. At this time, the short steel of the lower group to be welded is placed on the loading push bar, and then the loading push bar is driven to push the lower group of short steel into the docking groove of the conveyor turntable; during the displacement of the loading push bar, the unloading push bar is driven to move synchronously through the connecting bar, so that the unloading push bar can push the welded long steel out of the docking groove of the conveyor turntable, thereby realizing the simultaneous loading and unloading of steel, and improving the operational convenience and welding efficiency of the overall structure.

[0011] Optionally, a plurality of rotating disks are rotatably mounted on the conveying turntable, and the plurality of rotating disks are correspondingly arranged with a plurality of docking grooves, and each of the docking grooves is opened on the outer peripheral wall of the corresponding rotating disk for steel to be embedded; the rotating shaft can rotate forward and reverse, and the rotating shaft is respectively provided with a first linkage component and a second linkage component, and when the rotating shaft rotates forward, the first linkage component forces the conveying turntable and the rotating disk to rotate synchronously around the central axis of the rotating shaft; when the rotating shaft reverses, the rotating shaft is disconnected from the conveying turntable, and the second linkage component forces the rotating disk to rotate around its own central axis.

[0012] By adopting the above technical solution, the docking groove is arranged on the rotating disk, so that the steel can both "revolve" around the central axis of the conveying turntable and "rotate" around the central axis of the rotating disk, and the "revolution" and "rotation" of the rotating disk are controlled by the forward and reverse rotation of the rotating shaft; the purpose of "revolution" is to enable the steel to be transferred between the loading station, the welding station and the unloading station; the purpose of "rotation" is that when the steel is transferred to the welding station for welding, the rotating disk can rotate, thereby driving the steel at the welding station to turn over; with the cooperation of the rotating disk and the robotic arm, the robotic arm does not need a large swing amplitude to perform all-round welding of the steel, thereby improving the welding efficiency and reducing the later maintenance cost of the robotic arm.

[0013] Optionally, the first linkage assembly includes a linkage sleeve, a linkage ring, a movable ring, a linkage block and a return spring, the linkage sleeve being coaxially arranged on the surface of the conveying turntable, and the linkage ring being coaxially arranged on the outer peripheral wall of the rotating shaft; the movable ring sleeve is arranged on the outer peripheral wall of the rotating shaft and is located in the linkage sleeve, the outer peripheral wall of the movable ring is provided with a sliding block, the inner wall of the linkage sleeve is provided with a sliding groove for the sliding block to slide, and the movable ring is slidably installed in the linkage sleeve through the sliding block; the return spring is arranged between the movable ring and the conveying turntable, and the return spring forces the movable ring to be partially exposed from the linkage sleeve; the linkage block is arranged on the surface of the linkage ring close to the linkage sleeve, and the linkage block respectively has a pushing surface and a guiding surface, when the rotating shaft rotates forward, the pushing surface of the linkage block pushes the sliding block of the movable ring, and causes the movable ring to rotate around the central axis of the rotating shaft; when the rotating shaft is reversed, the guide surface of the linkage block pushes the sliding block to move into the linkage sleeve to disconnect the linkage ring and the linkage sleeve.

[0014] By adopting the above technical solution, when the rotating shaft rotates forward, the rotating shaft drives the linkage ring to rotate forward, and the pushing surface of the linkage block can push the sliding block of the movable ring, so that the movable ring rotates with the rotating shaft, thereby driving the conveying turntable and the rotating disk to rotate synchronously, realizing the linkage of the rotating shaft and the conveying turntable, and ensuring that the short steel can be transferred from the loading station, welding station and unloading station in sequence. When the rotating shaft is reversed, the guide surface of the linkage block pushes the sliding block into the linkage sleeve, so that the linkage ring and the linkage sleeve are disconnected, thereby releasing the linkage between the rotating shaft and the conveying turntable, so that the second linkage component can force the rotating disk to "rotate", improving the convenience of operation of the overall structure.

[0015] Optionally, the second linkage assembly includes a driving gear and multiple driven gears, the driving gear is coaxially fixed to the outer peripheral wall of the rotating shaft, the multiple driven gears are arranged corresponding to the multiple rotating disks, each of the driven gears is coaxially fixed to the outer peripheral wall of the corresponding rotating disk, and the driving gear and all the driven gears are meshed for transmission.

[0016] By adopting the above technical solution, when the rotating shaft rotates forward and drives the conveying turntable to rotate, the driving gear and the driven gear rotate synchronously around the central axis of the rotating shaft, that is, there is no relative rotation between the driving gear and the driven gear, and the rotating disk cannot "rotate" at this time; when the rotating shaft rotates reversely, the rotating shaft and the conveying turntable are disconnected, and the rotating shaft drives the driving gear to rotate, and the rotating disk can be driven to "rotate" through the driven gear, thereby realizing the rotation adjustment of the short steel on the rotating disk.

[0017] Optionally, each of the driven gears is provided with an avoidance gap, which is used to avoid steel so that the steel can enter and exit the docking groove; a plurality of connecting gears are rotatably installed on the surface of the conveying turntable, and the plurality of rotating disks and the plurality of connecting gears are arranged in a staggered manner around the central axis of the conveying turntable, and each of the connecting gears is meshed with the driven gears of two adjacent rotating disks for transmission; a plurality of reversing gears are rotatably installed on the surface of the conveying turntable, and the plurality of reversing gears and the plurality of connecting gears are correspondingly arranged, and each of the reversing gears is meshed with the corresponding connecting gear for transmission, and is meshed with the driving gear for transmission.

[0018] By adopting the above technical solution, the design of the avoidance gap allows the steel to smoothly enter and exit the docking groove, and the setting of the connecting gear allows multiple rotating disks to achieve synchronous rotation, that is, the active gear and the driven gear can always maintain a meshing relationship (indirect meshing), avoiding the situation where the active gear cannot drive the driven gear to continue to rotate due to the existence of the avoidance gap. The introduction of the reversing gear is used to change the direction of the rotating disk, so that when the rotating shaft reverses to drive the rotating disk to "rotate", the rotation direction of the rotating disk "rotates" can be consistent with the rotation direction of the rotating shaft, thereby reducing the possibility of the steel on the rotating disk being separated from the magnet block under the action of its own gravity during the rotation of the rotating disk located in the loading station, and improving the stability of the connection between the rotating disk and the steel.

[0019] Optionally, the mounting bracket is provided with a limit plate, and a limit assembly is provided between the limit plate and the linkage sleeve, and when the rotating shaft is reversed, the limit assembly stops the linkage sleeve from rotating.

[0020] By adopting the above-mentioned technical solution, the limit assembly arranged between the limit plate and the linkage sleeve can stop the linkage sleeve from rotating when the rotating shaft is reversed, preventing the linkage sleeve from rotating in the opposite direction along with the rotating shaft, thereby ensuring the relative position between the conveying turntable and the rotating disk is stable, avoiding the misalignment of the steel on the conveying turntable due to the reverse rotation of the linkage sleeve, and ensuring the smooth progress of the welding process.

[0021] Optionally, the limiting assembly includes a limiting ratchet, a limiting pawl and a torsion spring, the limiting ratchet is coaxially fixed to the outer peripheral wall of the linkage sleeve, one end of the limiting pawl is hinged to the limiting plate, and the torsion spring is arranged at the hinge between the limiting pawl and the limiting plate, and the torsion spring forces the limiting pawl to embed into the tooth groove of the limiting ratchet.

[0022] By adopting the above-mentioned technical solution, when the rotating shaft is reversed, the limit pawl is embedded in the tooth groove of the limit ratchet under the action of the torsion spring, and the linkage sleeve is stopped from rotating, thereby preventing the conveying turntable from rotating with the rotating shaft, ensuring that the switching action between the first linkage component and the second linkage component is accurate, thereby improving the overall stability and reliability of the device.

[0023] Optionally, the limit plate has an arcuate surface, the arcuate surface abuts against the outer peripheral wall of the linkage sleeve, and the arcuate surface is provided with a limit groove; the limit assembly includes a limit column and a limit spring, the limit column is arranged in the limit groove, the inner wall of the limit groove has a guide surface, the guide surface has a first side position and a second side position, the distance from the first side position to the center of the linkage sleeve is greater than the distance from the second side position to the center of the linkage sleeve; one end of the limit spring is connected to the limit column, and the other end is connected to the inner wall of the limit groove, the limit spring forces the limit column to move toward the second side position and simultaneously abuts against the guide surface and the outer peripheral wall of the linkage sleeve.

[0024] By adopting the above technical solution, when the rotating shaft rotates forward, it drives the conveying turntable to rotate. During the rotation of the conveying turntable, the outer peripheral wall of the linkage sleeve pushes the limit post to move toward the first side position, and the limit post cannot limit the rotation of the conveying turntable. When the rotating shaft reverses to drive the rotating disk to rotate, the conveying turntable has a tendency to reverse under the action of the guide surface of the linkage block, so that the outer peripheral wall of the linkage sleeve of the conveying turntable can push the limit post to move toward the second side position, forcing the limit post to abut against the guide surface and the outer peripheral wall of the linkage sleeve at the same time, and the friction between the linkage sleeve and the limit plate increases, so that the conveying turntable cannot reverse with the rotating shaft, achieving the anti-rotation effect of the conveying turntable, reducing the possibility of the conveying turntable reversing with the rotating shaft when the rotating shaft reverses, and improving the stability of the overall structure.

[0025] In summary, the present application includes at least one of the following beneficial technical effects: 1. Through the setting of the conveyor turntable and the welding assembly, during welding, the two short steels to be welded are placed on the loading station, and pushed into the conveyor turntable by the loading assembly, and then the conveyor turntable is driven to rotate by the rotating shaft to transfer the short steels to the welding station. The welding station is located on the top of the conveyor turntable, thereby raising the short steels. With the swing of the robotic arm, the welding gun can weld the steels in all directions, thereby improving the welding quality. After the welding is completed, the conveyor turntable is continued to be driven to rotate, and the long steels are transferred to the unloading station and pushed out by the unloading assembly, thereby improving the welding efficiency of the overall structure. 2. Through the arrangement of the first linkage assembly and the second linkage assembly, the docking groove is arranged on the rotating disk, so that the steel can both "revolve" around the central axis of the conveying turntable and "rotate" around the central axis of the rotating disk, and the "revolution" and "rotation" of the rotating disk are controlled by the forward and reverse rotation of the rotating shaft; the purpose of "revolution" is to enable the steel to be transferred between the loading station, the welding station and the unloading station; the purpose of "rotation" is that when the steel is transferred to the welding station for welding, the rotating disk can rotate, thereby driving the steel at the welding station to turn over; with the cooperation of the rotating disk and the mechanical arm, the mechanical arm can perform all-round welding of the steel without a large swing amplitude, thereby improving the welding efficiency and reducing the maintenance cost of the mechanical arm in the later stage; 3. Through the setting of the limit column and the limit spring, when the rotating shaft rotates forward, it drives the conveying turntable to rotate. During the rotation of the conveying turntable, the outer peripheral wall of the linkage sleeve pushes the limit column to move toward the first side position. At this time, the limit column cannot limit the rotation of the conveying turntable. When the rotating shaft reverses to drive the rotating disk to rotate, the conveying turntable has a tendency to reverse under the action of the guide surface of the linkage block, so that the outer peripheral wall of the linkage sleeve of the conveying turntable can push the limit column to move toward the second side position, forcing the limit column to abut against the guide surface and the outer peripheral wall of the linkage sleeve at the same time, and the friction between the linkage sleeve and the limit plate increases, so that the conveying turntable cannot reverse with the rotating shaft, achieving the anti-rotation effect of the conveying turntable, reducing the possibility of the conveying turntable reversing with the rotating shaft when the rotating shaft reverses, and improving the stability of the overall structure.

[0028] The following combination Figure 1-Figure 10 This application is described in further detail.

[0029] Embodiment 1, The embodiment of the present application discloses a welding device for steel processing.

[0030] Reference Figure 1 , Figure 2 A welding device for steel processing includes a mounting frame 1, a conveying turntable 2, a loading assembly 3, a unloading assembly 5 and a welding assembly 4. The mounting frame 1 is rotatably mounted with a rotating shaft 11. In this embodiment, the conveying turntable 2 is coaxially fixed to the outer peripheral wall of the rotating shaft 11, and a plurality of conveying turntables 2 are arranged at intervals along the central axis of the rotating shaft 11. All conveying turntables 2 are rotatably mounted on the mounting frame 1 through the rotating shaft 11; the mounting frame 1 is installed with a driving motor 15, and the output shaft of the driving motor 15 is coaxially connected to the rotating shaft 11 for driving the rotating shaft 11 to rotate.

[0031] Reference Figure 2 , Figure 3A loading station 21, a welding station 22 and a unloading station 23 are arranged on the outer side of the conveying turntable 2. The loading station 21, the welding station 22 and the unloading station 23 are arranged in sequence around the central axis of the conveying turntable 2. The welding station 22 is located at the top of the conveying turntable 2, and the loading station 21 and the unloading station 23 are arranged on both sides of the welding station 22. In this embodiment, the outer peripheral wall of each conveying turntable 2 is provided with a docking groove 24 for steel to be embedded. There are four docking grooves 24, and the multiple docking grooves 24 are arranged at intervals around the central axis of the conveying turntable 2. The inner wall of each docking groove 24 is embedded with a magnet block (not shown in the figure) for magnetically attracting steel.

[0032] Reference Figure 2 , Figure 3 A loading platform 12 is installed on one side of the mounting frame 1. The loading platform 12 is located in the loading station 21. The loading assembly 3 is arranged at the loading station 21 to push the short steel into the docking groove 24 of the conveying turntable 2; the loading assembly 3 includes a loading push bar 31, a push cylinder 32 and a correction alignment member. The loading push bar 31 is slidably installed on the surface of the loading platform 12. The loading push bar 31 is in the shape of a long strip. The length direction of the loading push bar 31 is consistent with the length direction of the rotating shaft 11. The cross section of the loading push bar 31 is “L shape" to form a loading area 311 for placing short steel materials. When the docking groove 24 of the conveying turntable 2 is transferred into the loading station 21, the loading area 311 is opposite to the docking groove 24 of the conveying turntable 2. It should be noted that a plurality of avoidance grooves 312 are provided on the side wall of the loading push bar 31 close to the rotating shaft 11. The plurality of avoidance grooves 312 are used to avoid the plurality of conveying turntables 2 on the rotating shaft 11 to ensure that when the loading push bar 31 is displaced toward the rotating shaft 11, the short steel materials can be pushed into the docking groove 24 of the conveying turntable 2.

[0033] Reference Figure 2 , Figure 3 The cylinder body of the pushing cylinder 32 is fixedly installed on the surface of the loading platform 12, and the piston rod of the pushing cylinder 32 is fixedly connected to the loading pushing bar 31 to drive the loading pushing bar 31 to approach or move away from the conveying turntable 2. When the piston rod of the pushing cylinder 32 is pushed outward, the loading pushing bar 31 pushes the short steel toward the conveying turntable 2.

[0034] Reference Figure 1 , Figure 2The deflection correction and alignment parts are arranged on the loading platform 12 to correct the deflection and align the short steel materials so as to keep the two short steel materials aligned for subsequent welding. Two groups of deflection correction and alignment parts are arranged and the two groups of deflection correction and alignment parts are symmetrically distributed at both ends of the loading and pushing strip 31; the deflection correction and alignment parts include a deflection correction and alignment strip 33, a screw 34 and a handwheel 35. The deflection correction and alignment strip 33 is fixed with a guide rod 331, and the guide rod 331 is slidably penetrated on the loading platform 12. The deflection correction and alignment strip 33 is slidably installed on the surface of the loading platform 12 through the guide rod 331 so as to be able to approach or move away from the loading and pushing strip 31; the screw 34 is rotatably installed on the top of the loading platform 12, the screw 34 is penetrated through the deflection correction and alignment strip 33 and is threadedly connected with the deflection correction and alignment strip 33 (the thread of the screw 34 is not shown in the figure); the handwheel 35 is coaxially fixed to one end of the screw 34.

[0035] Reference Figure 1 The welding assembly 4 includes a robot arm 41 and a welding gun 42. The robot arm 41 is fixedly mounted on the surface of the loading platform 12. The welding gun 42 is mounted on the robot arm 41 for welding the short steel in the welding station 22 (the robot arm 41 and the welding gun 42 are both existing technical structures, and the structures of the two are not elaborated too much here). The welding gun 42 is adjusted in position by the robot arm 41 to improve the flexibility of the welding gun 42, thereby improving the convenience of welding the steel. After the two short steels are welded by the welding gun 42, a long steel is formed.

[0036] Reference Figure 2 , Figure 3 A discharge platform 13 is installed on the side of the mounting frame 1 away from the loading platform 12 (that is, the discharge platform 13 is located in the discharge station 23), and the discharge assembly 5 is arranged in the discharge station 23 for pushing the long steel out of the conveying turntable 2; in this embodiment, the discharge assembly 5 includes a discharge pushing bar 51 and a connecting bar 52, and the discharge pushing bar 51 is slidably installed on the surface of the discharge platform 13, and the shape of the discharge pushing bar 51 is adapted to the shape of the loading pushing bar 31, that is, the cross-section of the discharge pushing bar 51 is also set to an "L shape", and a discharge area 511 is formed. When the conveying turntable 2 drives the docking groove 24 to rotate into the discharge station 23, the long steel is embedded in the discharge area 511; a plurality of discharge pushing bars 51 are provided, and the plurality of discharge pushing bars 51 are arranged at intervals along the length direction of the rotating shaft 11, and the discharge pushing bar 51 is located between two adjacent conveying turntables 2.

[0037] One end of the connecting bar 52 is fixedly connected to the unloading pushing bar 51, and the other end passes over the mounting frame 1 and is fixedly connected to the loading pushing bar 31. Each unloading pushing bar 51 is connected to the loading pushing bar 31 through its corresponding connecting bar 52, so that the loading pushing bar 31 and the unloading pushing bar 51 are interconnected as a whole; when the loading pushing bar 31 pushes the short steel to be welded into the conveying turntable 2, the loading pushing bar 31 drives the unloading pushing bar 51 to move synchronously, so that the unloading pushing bar 51 pushes the welded long steel out of the conveying turntable 2.

[0038] It should be noted that, in this embodiment, the length of the unloading platform 13 is smaller than the length of the long steel, that is, when the long steel is pushed to the unloading platform 13, both ends of the long steel are exposed on the unloading platform 13, so that the operator can move it away from the unloading platform 13.

[0039] The implementation principle of Example 1 of the present application is as follows: according to the length of the short steel, the position of the correction alignment bar 33 is adjusted in advance (in batch welding, this step is only performed during the first welding), and then the two short steels are placed on the feeding push bar 31 to keep the two short steels aligned. Then the feeding push bar 31 is driven to move toward the rotating shaft 11, and the short steel is pushed into the docking groove 24 of the conveying turntable 2. The magnetic block of the docking groove 24 can magnetically fix the short steel, so that the two short steels are fixed on multiple conveying turntables 2. Then, all the conveying turntables 2 are driven to rotate synchronously through the rotating shaft 11 to transfer the short steel to the welding station 22 for welding. The setting of the mechanical arm 41 greatly improves the flexibility of the welding gun 42. In addition, the welding station 22 is set on the top of the conveying turntable 2 to raise the short steel, so that the welding gun 42 can perform all-round welding operations on the steel, thereby improving the convenience of operation and welding quality of the overall structure.

[0040] After welding is completed, continue to drive the conveyor turntable 2 to rotate, so that the welded long steel can be transferred to the unloading station 23; at this time, the short steel to be welded in the lower group is placed on the loading push bar 31 and pushed into the docking groove 24 of the conveyor turntable 2. When the loading push bar 31 moves, the unloading push bar 51 is driven to move synchronously to push the welded long steel out of the conveyor turntable 2, so that the loading and unloading of the steel are carried out synchronously, which greatly improves the welding efficiency of the overall structure.

[0041] Embodiment 2, The embodiment of the present application discloses a welding device for steel processing.

[0042] Reference Figure 4 The difference between the welding device for steel processing disclosed in the embodiment of the present application and the embodiment 1 is that: The outer peripheral wall of the conveying turntable 2 is provided with a plurality of rotating grooves 26, and the plurality of rotating grooves 26 are arranged at intervals around the central axis of the conveying turntable 2. A rotating disk 25 is installed in each rotating groove 26, and the rotating disk 25 is rotatably installed in the rotating groove 26 so as to be able to rotate around its own central axis. When the conveying turntable 2 rotates, the rotating disk 25 can revolve around the central axis of the rotating shaft 11; in this embodiment, the docking groove 24 is provided on the outer peripheral wall of the rotating disk 25, and the plurality of rotating disks 25 form a plurality of docking grooves 24 for steel to be embedded; and it should be noted that the driving motor 15 in this embodiment is configured as a three-phase asynchronous motor so that the rotating shaft 11 can rotate forward and reverse.

[0043] Reference Figure 4 The rotating shaft 11 is respectively provided with a first linkage assembly 6 and a second linkage assembly 7. When the rotating shaft 11 rotates forward, the first linkage assembly 6 forces the conveying turntable 2 and the rotating disk 25 to rotate synchronously around the central axis of the rotating shaft 11. In other words, when the rotating shaft 11 rotates forward, the steel can be transferred from the loading station 21, the welding station 22 and the unloading station 23 in sequence.

[0044] When the rotating shaft 11 reverses, the rotating shaft 11 and the conveying turntable 2 are disconnected, and the second linkage assembly 7 forces the rotating disk 25 to rotate around its own central axis. In other words, when the rotating shaft 11 reverses, the conveying turntable 2 does not rotate, but the rotating disk 25 rotates on its own.

[0045] Reference Figure 5 , Figure 6 The first linkage component 6 includes a linkage sleeve 61, a linkage ring 62, a movable ring 63, a linkage block 64 and a reset spring 65. The linkage sleeve 61 is coaxially fixed to the surface of the conveying turntable 2, the linkage ring 62 is coaxially fixed to the outer peripheral wall of the rotating shaft 11, the movable ring 63 is sleeved on the outer peripheral wall of the rotating shaft 11 and is located in the linkage sleeve 61, and the outer peripheral wall of the movable ring 63 is integrally formed with a plurality of sliding blocks 631, and the plurality of sliding blocks 631 are arranged at intervals around the central axis of the movable ring 63. The inner peripheral wall of the linkage sleeve 61 is provided with a plurality of sliding grooves 611, and the plurality of sliding grooves 611 are correspondingly arranged with the plurality of sliding blocks 631, and each sliding block 631 is slidably installed in the corresponding sliding groove 611, and both ends of each sliding groove 611 are extended along the length direction of the rotating shaft 11, and the movable ring 63 is slidably installed in the linkage sleeve 61 through the plurality of sliding blocks 631.

[0046] There are multiple return springs 65, one end of the return spring 65 is fixedly connected to the movable ring 63, and the other end is fixedly connected to the surface of the conveying turntable 2. The return spring 65 normally forces the movable ring 63 to be partially exposed from the linkage sleeve 61; the linkage block 64 is fixedly installed on the surface of the linkage ring 62 close to the linkage sleeve 61. In this embodiment, there are multiple linkage blocks 64, and the multiple linkage blocks 64 are arranged at intervals around the central axis of the linkage ring 62, and the number of linkage blocks 64 is corresponding to the number of sliding blocks 631 of the movable ring 63. When the movable ring 63 is partially exposed from the linkage sleeve 61, the multiple linkage blocks 64 and the multiple sliding blocks 631 are staggered around the central axis of the rotating shaft 11 (that is, the linkage block 64 is embedded between two adjacent sliding blocks 631).

[0047] The linkage block 64 has a pushing surface 641 and a guiding surface 642. When the rotating shaft 11 rotates forward, the pushing surface 641 of the linkage block 64 pushes the sliding block 631 of the movable ring 63, and causes the movable ring 63 to rotate around the central axis of the rotating shaft 11; when the rotating shaft 11 rotates reversely, the guiding surface 642 of the linkage block 64 pushes the sliding block 631 to move into the linkage sleeve 61, so that the linkage ring 62 and the linkage sleeve 61 are disconnected.

[0048] Reference Figure 5 , Figure 7 The second linkage assembly 7 includes a driving gear 71 and a plurality of driven gears 72. The driving gear 71 is coaxially fixed to the outer peripheral wall of the rotating shaft 11. The plurality of driven gears 72 are arranged corresponding to the plurality of rotating disks 25. Each driven gear 72 is coaxially fixed to the outer peripheral wall of the corresponding rotating disk 25. The driving gear 71 and the plurality of driven gears 72 are located on the side of the conveying turntable 2 away from the linkage sleeve 61. Each driven gear 72 is provided with an avoidance gap 721, which is used to avoid steel so that the steel can enter and exit the docking groove 24 of the rotating disk 25.

[0049] A plurality of connecting gears 73 are rotatably mounted on the surface of the conveying turntable 2 away from the linkage sleeve 61. The plurality of rotating disks 25 and the plurality of connecting gears 73 are arranged in a staggered manner around the central axis of the conveying turntable 2. Each connecting gear 73 is meshed with the driven gears 72 of two adjacent rotating disks 25 for transmission. A plurality of reversing gears 74 are rotatably mounted on the surface of the conveying turntable 2 away from the linkage sleeve 61. The plurality of reversing gears 74 and the plurality of connecting gears 73 are correspondingly arranged. Each reversing gear 74 is meshed with the corresponding connecting gear 73 for transmission, and is also meshed with the driving gear 71 for transmission. The reversing gears 74 and the connecting gears 73 are arranged so that the driving gear 71 and all the driven gears 72 are meshed with each other for transmission.

[0050] It is particularly noted that in the present embodiment, the reversing gear 74 is arranged so that when the rotating disk 25 rotates, the rotation direction of the rotating disk 25 is consistent with the forward rotation direction of the rotating shaft 11; such a design makes it difficult for the steel in the rotating disk 25 to fall off when the rotating disk 25 is located at the loading station 21 and rotates, thereby improving the stability of the connection between the rotating disk 25 and the steel.

[0051] Reference Figure 4 , Figure 8 The mounting frame 1 is fixedly mounted with a plurality of limit plates 14, and the plurality of limit plates 14 are arranged corresponding to the plurality of conveying turntables 2. A limit assembly 8 is arranged between each limit plate 14 and the linkage sleeve 61 of the corresponding conveying turntable 2. When the rotating shaft 11 is reversed, the limit assembly 8 stops the linkage sleeve 61 from rotating.

[0052] In this embodiment, the limiting assembly 8 includes a limiting ratchet 81, a limiting pawl 82 and a torsion spring. The limiting ratchet 81 is coaxially fixed to the outer peripheral wall of the linkage sleeve 61, and one end of the limiting pawl 82 is hinged to the plate surface of the limiting plate 14; the torsion spring (not shown in the figure) is installed at the hinge between the limiting pawl 82 and the limiting plate 14, and the torsion spring forces the limiting pawl 82 to embed into the tooth groove of the limiting ratchet 81; in order to improve the limiting effect, the number of limiting pawls 82 can be set to multiple; with such a design, the cooperation between the limiting ratchet 81 and the limiting pawl 82 enables the conveying turntable 2 to only rotate forward following the rotating shaft 11, but cannot rotate reversely following the rotating shaft 11.

[0053] The implementation principle of Example 2 of the present application is as follows: in the specific operation of this embodiment, after the short steel is pushed into the docking groove 24 of the rotating disk 25 of the conveying turntable 2 by the loading station 21, the rotating shaft 11 is forced to reverse, driving the rotating disk 25 to rotate half a circle, and the rotating disk 25 can transfer the steel into the rotating groove 26, so that the inner wall of the docking groove 24 and the inner wall of the rotating groove 26 can jointly limit the short steel, thereby improving the connection stability between the steel and the rotating disk 25.

[0054] Then, the rotating shaft 11 is driven to rotate forward, forcing the rotating disk 25 to be transferred to the welding station 22 for welding. During the welding process, the rotating shaft 11 is driven to rotate reversely, so that the rotating disk 25 located at the welding station 22 can rotate on its own, driving the steel in the welding station 22 to rotate, so that the welding gun 42 can weld the short steel in the welding station 22 in all directions. The cooperation between the mechanical arm 41 and the rotating disk 25 greatly reduces the swing amplitude of the mechanical arm 41 (that is, the mechanical arm 41 only needs to swing at a small angle, and cooperate with the rotation of the rotating disk 25 to weld the steel in all directions), thereby improving the welding efficiency and reducing the subsequent maintenance cost of the mechanical arm 41.

[0055] After welding is completed, the rotating shaft 11 is driven to rotate forward, forcing the welded long steel to be transferred to the unloading station 23. At this time, the lower group of short steels to be welded are sent into the rotating disk 25 located at the loading station 21 through the loading push bar 31, and the long steel on the rotating disk 25 located at the unloading station 23 can be pushed out synchronously, thereby improving the operational convenience of the overall structure.

[0056] Embodiment 3, The embodiment of the present application discloses a welding device for steel processing.

[0057] Reference Fig. 9 , Fig.10 The difference between the welding device for steel processing disclosed in the embodiment of the present application and the embodiment 2 is that: In this embodiment, the top wall of the limit plate 14 has an arcuate surface 141, the arcuate surface 141 abuts against the outer peripheral wall of the linkage sleeve 61, and the arcuate surface 141 opens a limit groove 142; the limit assembly 8 includes a limit column 83 and a limit spring 84, the limit column 83 is arranged in the limit groove 142, and the inner wall of the limit groove 142 has a guide surface 143, the guide surface 143 has a first side position 144 and a second side position 145, and the distance from the first side position 144 to the center of the linkage sleeve 61 is greater than the distance from the second side position 145 to the center of the linkage sleeve 61.

[0058] One end of the limit spring 84 is fixedly connected to the limit column 83, and the other end is fixedly connected to the inner wall of the limit groove 142. The limit spring 84 forces the limit column 83 to move toward the second side position 145, and at the same time abuts against the guide surface 143 and the outer peripheral wall of the linkage sleeve 61. When the rotating shaft 11 rotates forward, the outer peripheral wall of the linkage sleeve 61 of the conveying turntable 2 drives the limit column 83 to move toward the first side position 144. When the rotating shaft 11 reverses, the outer peripheral wall of the linkage sleeve 61 of the conveying rotation drives the limit column 83 to move toward the second side position 145.

[0059] The implementation principle of Example 3 of the present application is: when the rotating shaft 11 rotates forward, it drives the conveying turntable 2 to rotate for transferring steel. During the rotation of the conveying turntable 2, the outer peripheral wall of the linkage sleeve 61 pushes the limiting column 83 to move toward the first side position 144, so that the conveying turntable 2 can follow the rotating shaft 11 to rotate forward (that is, the conveying turntable 2 can transfer steel). When the rotating shaft 11 is reversed to drive the rotating disk 25 to rotate, the conveying turntable 2 has a tendency to reverse under the action of the guide surface 642 of the linkage block 64, so that the outer peripheral wall of the linkage sleeve 61 of the conveying turntable 2 can push the limiting column 83 to move toward the second side position 145, forcing the limiting column 83 to simultaneously abut against the guide surface 143 and the outer peripheral wall of the linkage sleeve 61, and the friction between the linkage sleeve 61 and the limiting plate 14 is increased, so that the conveying turntable 2 cannot reverse with the rotating shaft 11, thereby achieving the anti-rotation effect of the conveying turntable 2, reducing the possibility of the conveying turntable 2 following the rotating shaft 11 to reverse when the rotating shaft 11 is reversed, and improving the stability of the overall structure.

[0060] The above are preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
