Description

Technical Field

[0001] This application relates to the technical field of steel welding, and particularly 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 for improving the construction efficiency of the entire project.

[0003] When welding traditional short steel bars, excessive reliance is placed on manual operation. That is, the operator needs to place two short steel bars at the welding station and align the heads and tails of the two short steel bars. Then, welding is carried out with a welding torch. After welding, it is taken out and the next set of short steel bars is welded. However, although this type of welding method is highly flexible, the welding efficiency is low, and it is easily affected by the skills and state of the operator, resulting in obvious differences in the welding quality of each long steel bar, making it difficult to meet the needs of large-scale production. Therefore, further improvement is needed. Summary of the Invention

[0004] In order to improve the welding efficiency and welding quality between short steel bars, this application provides a welding device for steel processing.

[0005] The welding device for steel processing provided by this application adopts the following technical solutions:

[0006] A welding device for steel processing includes a mounting frame, a conveying turntable, a feeding assembly, a welding assembly, and a discharging assembly. The mounting frame is rotatably installed with a rotating shaft, and the conveying turntable is coaxially arranged on the rotating shaft and is provided with a plurality of them at intervals along the central axis of the rotating shaft. The outer side of the conveying turntable is successively provided with a feeding station, a welding station, and a discharging station. The feeding assembly is arranged at the feeding station to push short steel bars into the conveying turntable, and the discharging assembly is arranged at the discharging station to push long steel bars out of the conveying turntable. The welding station is located at the top of the conveying turntable. The welding assembly includes a robotic arm and a welding torch. The robotic arm is arranged on one side of the mounting frame, and the welding torch is arranged on the robotic arm to weld the short steel bars in the welding station.

[0007] By adopting the above technical solution, during welding, the two short steel materials to be welded are placed on the loading station, and are pushed into the conveying turntable by the loading component. Then, the conveying turntable is driven to rotate by the rotating shaft to transfer the short steel materials to the welding station. The welding station is located at the top of the conveying turntable, thus raising the short steel materials. Cooperating with the swing of the robotic arm, the welding torch can weld the steel materials in all directions, improving the welding quality. After welding, the conveying turntable is continuously driven to rotate, and the long steel materials are transferred to the unloading station and pushed out by the unloading component, improving the welding efficiency of the overall structure.

[0008] Optionally, the outer peripheral side of the conveying turntable has a plurality of docking grooves for the steel materials to be inserted. The plurality of docking grooves are arranged at intervals around the central axis of the conveying turntable. Magnet blocks for magnetically attracting the steel materials are embedded in the inner walls of the docking grooves; a loading table is provided on one side of the mounting frame, and the loading table is located within the loading station; the loading component includes a loading push bar, a push cylinder, and a deviation correction and alignment component. The loading push bar is slidably mounted on the loading table, and the loading push bar has a loading area for placing the short steel materials; the push cylinder is arranged on the loading table to drive the loading push bar to approach or move away from the conveying turntable; the deviation correction and alignment component is arranged on the loading table to perform deviation correction and alignment on the short steel materials.

[0009] By adopting the above technical solution, the 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 the deviation correction and alignment component. Then, the loading push bar is pushed towards the conveying turntable by the push cylinder, so that the short steel materials are inserted into the docking grooves of the conveying turntable. The magnet blocks in the docking grooves can magnetically attract the short steel materials, thereby fixing the short steel materials on the conveying turntable, facilitating the transfer of the short steel materials by the conveying turntable, and improving the convenience of loading the short steel materials.

[0010] Optionally, an unloading table is provided on one side of the mounting frame, and the unloading table is located within the unloading station; the unloading component includes an unloading push bar and a connecting bar. The unloading push bar is slidably mounted on the unloading table. One end of the connecting bar is connected to the unloading push bar, and the other end crosses the mounting frame and is connected to the loading push bar. The loading push bar and the unloading push bar are connected to each other through the connecting bar; when the loading push bar pushes the short steel materials to be welded into the conveying turntable, the unloading push bar pushes the long steel materials that have been welded out of the conveying turntable.

[0011] By adopting the above technical solution, after the short steel materials are transferred to the welding station and welded, the conveying turntable is continuously driven to rotate to transfer the welded long steel materials to the blanking station. At this time, the next group of short steel materials to be welded are placed on the feeding pushing bar, and then the feeding pushing bar is driven to push the next group of short steel materials into the docking groove of the conveying turntable. During the displacement of the feeding pushing bar, the blanking pushing bar is driven to displace synchronously through the connecting bar, so that the blanking pushing bar can push the welded long steel materials out of the docking groove of the conveying turntable, realizing the synchronous feeding and blanking of the steel materials, and improving the operation convenience and welding efficiency of the overall structure.

[0012] Optionally, a plurality of rotating discs are rotatably installed on the conveying turntable, and the plurality of rotating discs are correspondingly arranged with the plurality of docking grooves. Each docking groove is formed on the outer peripheral wall of the corresponding rotating disc for the steel materials to be inserted; the rotating shaft can rotate forward and backward, and the rotating shaft is respectively provided with a first linkage assembly and a second linkage assembly. When the rotating shaft rotates forward, the first linkage assembly forces the conveying turntable and the rotating disc to rotate synchronously around the central axis of the rotating shaft; when the rotating shaft rotates backward, the connection between the rotating shaft and the conveying turntable is disengaged, and the second linkage assembly forces the rotating disc to rotate around its own central axis.

[0013] By adopting the above technical solution, the docking groove is arranged on the rotating disc, so that the steel materials can both perform "revolution" around the central axis of the conveying turntable and "rotation" around the central axis of the rotating disc, and the "revolution" and "rotation" of the rotating disc are controlled by the forward and reverse rotations of the rotating shaft; the purpose of "revolution" is to enable the steel materials to be transferred between the feeding station, the welding station and the blanking station; the purpose of "rotation" is that when the steel materials are transferred to the welding station for welding, the rotating disc can rotate, so as to drive the steel materials at the welding station to flip; with the cooperation of the rotating disc and the robotic arm, the robotic arm can weld the steel materials in all directions without a large swinging amplitude, improving the welding efficiency and reducing the later maintenance cost of the robotic arm.

[0014] 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 is coaxially disposed on the surface of the conveying turntable, and the linkage ring is coaxially disposed on the outer peripheral wall of the rotating shaft. The movable ring is sleeved on the outer peripheral wall of the rotating shaft and is located inside the linkage sleeve. A sliding block is provided on the outer peripheral wall of the movable ring, and a sliding groove for the sliding block to slide is formed on the inner wall of the linkage sleeve. The movable ring is slidably mounted inside the linkage sleeve through the sliding block. The return spring is disposed between the movable ring and the conveying turntable, and the return spring forces a part of the movable ring to be exposed outside the linkage sleeve. The linkage block is disposed on the surface of the linkage ring close to the linkage sleeve. The linkage block has a pushing surface and a guiding surface respectively. 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 rotates reversely, the guiding surface of the linkage block pushes the sliding block into the linkage sleeve, so as to disconnect the connection between the linkage ring and the linkage sleeve.

[0015] By adopting the above technical solution, when the rotating shaft rotates forward, the rotating shaft drives the linkage ring to rotate forward. The pushing surface of the linkage block can push the sliding block of the movable ring, so that the movable ring rotates together with the rotating shaft, thereby driving the conveying turntable and the rotating disk to rotate synchronously, realizing the linkage between the rotating shaft and the conveying turntable, and ensuring that the short steel bars can be transferred in sequence between the feeding station, the welding station, and the discharging station. When the rotating shaft rotates reversely, the guiding surface of the linkage block pushes the sliding block into the linkage sleeve, disconnecting the connection between the linkage ring and the linkage sleeve, thereby releasing the linkage between the rotating shaft and the conveying turntable, so that the second linkage assembly can force the rotating disk to perform "self-rotation", improving the operation convenience of the overall structure.

[0016] Optionally, the second linkage assembly includes a driving gear and a plurality of driven gears. The driving gear is coaxially fixed on the outer peripheral wall of the rotating shaft, and the plurality of driven gears are arranged corresponding to the plurality of rotating disks. Each driven gear is coaxially fixed on the outer peripheral wall of the corresponding rotating disk, and the driving gear and all the driven gears are in meshing transmission.

[0017] By adopting the above technical solution, when the rotating shaft rotates forward to drive the conveying turntable to rotate, the driving gear and the driven gears rotate synchronously around the central axis of the rotating shaft, that is, there is no relative rotation movement between the driving gear and the driven gears. At this time, the rotating disk cannot perform "self-rotation". When the rotating shaft rotates reversely, the connection between the rotating shaft and the conveying turntable is disconnected, and the rotating shaft drives the driving gear to rotate, so that the rotating disk can be driven to perform "self-rotation" through the driven gears, realizing the rotation adjustment of the short steel bars on the rotating disk.

[0018] Optionally, each of the driven gears is provided with an avoidance notch for avoiding steel materials to allow the steel materials to 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. Each connecting gear is meshed and driven with the driven gears of two adjacent rotating disks; 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 arranged in correspondence. Each reversing gear is meshed and driven with the corresponding connecting gear and is meshed and driven with the driving gear.

[0019] By adopting the above technical solution, the design of the avoidance notch enables the steel material to smoothly enter and exit the docking groove. The arrangement of the connecting gears enables synchronous rotation among the plurality of rotating disks, that is, it enables the driving gear and the driven gears to always maintain a meshing relationship (indirect meshing), avoiding the situation that the driving gear cannot drive the driven gears to continuously rotate due to the existence of the avoidance notch. The introduction of the reversing gear is used to change the rotation direction of the rotating disk, so that when the rotating shaft rotates reversely to drive the rotating disk to "rotate self", the rotation direction of the rotating disk's "self-rotation" can be consistent with the rotation direction of the forward rotation of the rotating shaft. Furthermore, it reduces the possibility that the steel material on the rotating disk disengages from the magnet block under the action of its own gravity during the rotation of the rotating disk located at the loading station, and improves the connection stability between the rotating disk and the steel material.

[0020] Optionally, a limiting plate is installed and erected, and a limiting component is arranged between the limiting plate and the linkage sleeve. When the rotating shaft rotates reversely, the limiting component stops the rotation of the linkage sleeve.

[0021] By adopting the above technical solution, the limiting component arranged between the limiting plate and the linkage sleeve can stop the rotation of the linkage sleeve when the rotating shaft rotates reversely, prevent the linkage sleeve from rotating reversely with the rotating shaft, ensure the relative position stability between the conveying turntable and the rotating disk, avoid the dislocation of the steel material on the conveying turntable due to the reverse rotation of the linkage sleeve, and ensure the smooth progress of the welding process.

[0022] Optionally, the limiting component includes a limiting ratchet wheel, a limiting pawl and a torsion spring. The limiting ratchet wheel is coaxially fixed on 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. The torsion spring forces the limiting pawl to be embedded in the tooth groove of the limiting ratchet wheel.

[0023] By adopting the above technical solution, when the rotating shaft rotates reversely, the limiting pawl is embedded in the tooth groove of the limiting ratchet wheel under the action of the torsion spring to stop the rotation of the linkage sleeve, prevent the conveying turntable from rotating with the rotating shaft, ensure the accurate switching action between the first linkage component and the second linkage component, and improve the overall stability and reliability of the device.

[0024] Optionally, the limiting plate has an arc surface which abuts against the outer peripheral wall of the linkage sleeve, and a limiting groove is formed in the arc surface; the limiting component includes a limiting post and a limiting spring. The limiting post is arranged in the limiting groove, the inner wall of the limiting groove has a guiding surface which has a first side position and a second side position, and 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 limiting spring is connected to the limiting post, and the other end is connected to the inner wall of the limiting groove. The limiting spring forces the limiting post to move towards the second side position and simultaneously abuts against the guiding surface and the outer peripheral wall of the linkage sleeve.

[0025] 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 limiting post towards the first side position, and at this time, the limiting post cannot limit the rotation of the conveying turntable. When the rotating shaft rotates in reverse to drive the rotating disc to rotate, the conveying turntable has a tendency to rotate in reverse under the action of the guiding surface of the linkage block, so that the outer peripheral wall of the linkage sleeve of the conveying turntable can push the limiting post towards the second side position, forcing the limiting post to abut against the guiding surface and the outer peripheral wall of the linkage sleeve at the same time, and increasing the friction force between the linkage sleeve and the limiting plate, so that the conveying turntable cannot rotate in reverse following the rotating shaft, realizing the anti-rotation effect on the conveying turntable, reducing the possibility that the conveying turntable rotates in reverse following the rotating shaft when the rotating shaft rotates in reverse, and improving the stability of the overall structure.

[0026] In summary, the present application includes at least one of the following beneficial technical effects:

[0027] 1. Through the arrangement of the conveying turntable and the welding assembly, during welding, the two short steel materials to be welded are placed at the feeding station and pushed into the conveying turntable by the feeding assembly, and then the conveying turntable is driven to rotate by the rotating shaft to transfer the short steel materials to the welding station. The welding station is located at the top of the conveying turntable, thus lifting the short steel materials, and cooperating with the swing of the robotic arm, enabling the welding torch to weld the steel materials in all directions, improving the welding quality; after welding is completed, the conveying turntable is continuously driven to rotate to transfer the long steel material to the discharging station and push it out by the discharging assembly, improving the welding efficiency of the overall structure;

[0028] 2. Through the settings of the first linkage component and the second linkage component, the docking groove is arranged on the rotating disk, enabling the steel to both "revolve" around the central axis of the conveying rotating disk and "rotate" around the central axis of the rotating disk. Moreover, the "revolution" and "rotation" of the rotating disk are controlled by the forward and reverse rotations of the rotating shaft. The purpose of "revolution" is to transfer the steel 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 flip. With the cooperation of the rotating disk and the robotic arm, the robotic arm can weld the steel in all directions without a large swing amplitude, improving the welding efficiency and reducing the later maintenance cost of the robotic arm.

[0029] 3. Through the settings of the limit post and the limit spring, when the rotating shaft rotates forward, it drives the conveying rotating disk to rotate. During the rotation of the conveying rotating disk, the outer peripheral wall of the linkage sleeve pushes the limit post to move towards the first side position, and at this time, the limit post cannot limit the rotation of the conveying rotating disk. When the rotating shaft rotates in reverse to drive the rotating disk to rotate, the conveying rotating disk has a tendency to rotate in reverse under the action of the guiding surface of the linkage block, enabling the outer peripheral wall of the linkage sleeve of the conveying rotating disk to push the limit post to displace towards the second side position, forcing the limit post to simultaneously abut against the guiding surface and the outer peripheral wall of the linkage sleeve. The friction between the linkage sleeve and the limit plate increases, thereby preventing the conveying rotating disk from rotating in reverse with the rotating shaft, achieving the effect of stopping the rotation of the conveying rotating disk, reducing the possibility of the conveying rotating disk rotating in reverse with the rotating shaft when the rotating shaft rotates in reverse, and improving the stability of the overall structure.

Detailed implementation manners

[0041] The following Figures 1 - 10 further describes the present application in detail.

[0042] Embodiment 1,

[0043] The embodiment of the present application discloses a welding device for steel processing.

[0044] Referring to Figure 1 and Figure 2 , a welding device for steel processing includes a mounting frame 1, a conveying turntable 2, a loading assembly 3, an unloading assembly 5, and a welding assembly 4. The mounting frame 1 is rotatably installed 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 the conveying turntables 2 are rotatably installed 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 to drive the rotating shaft 11 to rotate.

[0045] Referring to Figure 2 and Figure 3 Figure 3 , on the outer side of the conveying turntable 2, there are a loading station 21, a welding station 22 and an unloading station 23. 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 respectively arranged on both sides of the welding station 22. In this embodiment, on the outer peripheral wall of each conveying turntable 2, there are docking grooves 24 for steel bars to be embedded. The number of the docking grooves 24 is set to be four, and the multiple docking grooves 24 are arranged at intervals around the central axis of the conveying turntable 2. Inside the inner wall of each docking groove 24, there is a magnet block (not shown in the figure) for magnetically attracting the steel bars.

[0046] Referring to Figure 2 and Figure 3 Figure 3 , on one side of the mounting frame 1, there is a loading table 12. The loading table 12 is located inside the loading station 21. The loading assembly 3 is arranged at the loading station 21 for pushing the short steel bars into the docking grooves 24 of the conveying turntable 2. The loading assembly 3 includes a loading push bar 31, a push cylinder 32 and a deviation correction and alignment member. The loading push bar 31 is slidably mounted on the surface of the loading table 12. The loading push bar 31 is in a long strip shape, and the length direction of the loading push bar 31 is the same as the length direction of the rotating shaft 11. The cross-section of the loading push bar 31 is in an "L" shape to form a loading area 311 for placing the short steel bars. When the docking groove 24 of the conveying turntable 2 rotates into the loading station 21, the loading area 311 is directly opposite to the docking groove 24 of the conveying turntable 2. It should be noted that on the side wall of the loading push bar 31 close to the rotating shaft 11, there are multiple avoidance grooves 312 for avoiding the multiple conveying turntables 2 on the rotating shaft 11, so as to ensure that when the loading push bar 31 moves towards the rotating shaft 11, it can push the short steel bars into the docking grooves 24 of the conveying turntable 2.

[0047] Referring to Figure 2 and Figure 3 Figure 3 , the cylinder body of the push cylinder 32 is fixedly mounted on the surface of the loading table 12. The piston rod of the push cylinder 32 is fixedly connected to the loading push bar 31 for driving the loading push bar 31 to approach or move away from the conveying turntable 2. When the piston rod of the push cylinder 32 is pushed outwards, the loading push bar 31 pushes the short steel bars towards the conveying turntable 2.

[0048] Referring to Figure 1 and Figure 2, a deviation rectifying and aligning member is arranged on the loading table 12 for rectifying and aligning short steel materials, so as to keep the two short steel materials aligned, which is convenient for subsequent welding. There are two groups of deviation rectifying and aligning members, and the two groups of deviation rectifying and aligning members are symmetrically distributed at both ends of the loading and pushing bar 31; the deviation rectifying and aligning member includes a deviation rectifying and aligning bar 33, a screw rod 34 and a hand wheel 35. A guide rod 331 is fixed on the deviation rectifying and aligning bar 33. The guide rod 331 slidably penetrates through the loading table 12, and the deviation rectifying and aligning bar 33 is slidably installed on the surface of the loading table 12 through the guide rod 331, so as to be able to approach or move away from the loading and pushing bar 31; the screw rod 34 is rotatably installed on the top of the loading table 12, and the screw rod 34 penetrates through the deviation rectifying and aligning bar 33 and is threadedly connected with the deviation rectifying and aligning bar 33 (the thread of the screw rod 34 is not shown in the figure); the hand wheel 35 is coaxially fixed at one end of the screw rod 34.

[0049] Refer to Figure 1 , the welding assembly 4 includes a robotic arm 41 and a welding torch 42. The robotic arm 41 is fixedly installed on the surface of the loading table 12, and the welding torch 42 is installed on the robotic arm 41 for welding the short steel materials in the welding station 22 (both the robotic arm 41 and the welding torch 42 are structures of the prior art, and the structures of the two will not be elaborated too much here). The position of the welding torch 42 is adjusted through the robotic arm 41 to improve the flexibility of the welding torch 42, thereby improving the convenience of welding the steel materials. After the two short steel materials are welded by the welding torch 42, a long steel material is formed.

[0050] Refer to Figure 2 , Figure 3 , a blanking table 13 is installed on one side of the mounting frame 1 away from the loading table 12 (that is, the blanking table 13 is located in the blanking station 23), and a blanking assembly 5 is arranged in the blanking station 23 for pushing the long steel material out of the conveying turntable 2; in this embodiment, the blanking assembly 5 includes a blanking and pushing bar 51 and a connecting bar 52. The blanking and pushing bar 51 is slidably installed on the surface of the blanking table 13. The shape of the blanking and pushing bar 51 is adapted to the shape of the loading and pushing bar 31, that is, the cross section of the blanking and pushing bar 51 is also set as an "L shape", and a blanking area 511 is formed. When the conveying turntable 2 drives the docking groove 24 to turn into the blanking station 23, the long steel material is embedded in the blanking area 511; a plurality of blanking and pushing bars 51 are provided, and the plurality of blanking and pushing bars 51 are arranged at intervals along the length direction of the rotating shaft 11, and the blanking and pushing bars 51 are located between two adjacent conveying turntables 2.

[0051] One end of the connecting bar 52 is fixedly connected to the blanking pushing bar 51, and the other end passes over the mounting frame 1 and is fixedly connected to the feeding pushing bar 31. Each blanking pushing bar 51 is connected to the feeding pushing bar 31 through its respective corresponding connecting bar 52, so that the feeding pushing bar 31 and the blanking pushing bar 51 are interconnected as a whole. When the feeding pushing bar 31 pushes the short steel bars to be welded into the conveying turntable 2, the feeding pushing bar 31 drives the blanking pushing bar 51 to displace synchronously, so that the blanking pushing bar 51 pushes the welded long steel bars out of the conveying turntable 2.

[0052] It should be noted that in this embodiment, the length of the blanking table 13 is less than the length of the long steel bar, that is, when the long steel bar is pushed to the blanking table 13, both ends of the long steel bar are exposed outside the blanking table 13, so that the operator can carry it off the blanking table 13.

[0053] The implementation principle of Embodiment 1 of this application is as follows: According to the length of the short steel bar, the position of the deviation correction and alignment bar 33 is adjusted in advance (this step is only performed in the first welding during batch welding), and then the two short steel bars are placed on the feeding pushing bar 31 so that the two short steel bars are aligned with each other. Then, the feeding pushing bar 31 is driven to displace towards the rotating shaft 11 to push the short steel bar into the docking groove 24 of the conveying turntable 2. The magnetic attraction block in the docking groove 24 can magnetically fix the short steel bar, so that the two short steel bars are fixed on the plurality of conveying turntables 2. Then, all the conveying turntables 2 are driven to rotate synchronously by the rotating shaft 11 to transfer the short steel bar to the welding station 22 for welding. The setting of the robotic arm 41 greatly improves the flexibility of the welding torch 42. In addition, the welding station 22 is arranged on the top of the conveying turntable 2 to elevate the short steel bar, so that the welding torch 42 can perform all-round welding operations on the steel bar, improving the operation convenience and welding quality of the overall structure.

[0054] After welding is completed, continue to drive the conveying turntable 2 to rotate, and the welded long steel bar can be transferred to the blanking station 23; at this time, the next group of short steel bars to be welded are placed on the feeding pushing bar 31 and pushed into the docking groove 24 of the conveying turntable 2. When the feeding pushing bar 31 moves, it drives the blanking pushing bar 51 to displace synchronously to push the welded long steel bar out of the conveying turntable 2, so that the feeding and blanking of the steel bar are carried out synchronously, greatly improving the welding efficiency of the overall structure.

[0055] Embodiment 2

[0056] This application embodiment discloses a welding device for steel processing.

[0057] Refer to Figure 4 The difference between the welding device for steel processing disclosed in this application embodiment and Embodiment 1 is that:

[0058] A plurality of rotation grooves 26 are formed in the outer peripheral wall of the conveying turntable 2, and the plurality of rotation grooves 26 are arranged at intervals around the central axis of the conveying turntable 2. A rotating disk 25 is installed in each rotation groove 26. The rotating disk 25 is rotatably installed in the rotation 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 formed in 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 inserted; it should be noted that the driving motor 15 in this embodiment is set as a three-phase asynchronous motor so that the rotating shaft 11 can rotate forward and backward.

[0059] Referring to 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.

[0060] When the rotating shaft 11 rotates backward, the connection between the rotating shaft 11 and the conveying turntable 2 is 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 rotates backward, the conveying turntable 2 does not rotate, while the rotating disk 25 rotates self.

[0061] Referring to Figure 5 , Figure 6 , the first linkage assembly 6 includes a linkage sleeve 61, a linkage ring 62, a movable ring 63, a linkage block 64, and a return spring 65. The linkage sleeve 61 is coaxially fixed on the surface of the conveying turntable 2, the linkage ring 62 is coaxially fixed on 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 inside the linkage sleeve 61. A plurality of sliding blocks 631 are integrally formed on the outer peripheral wall of the movable ring 63, and the plurality of sliding blocks 631 are arranged at intervals around the central axis of the movable ring 63. A plurality of sliding grooves 611 are formed in the inner peripheral wall of the linkage sleeve 61, and the plurality of sliding grooves 611 are correspondingly arranged with the plurality of sliding blocks 631. Each sliding block 631 is slidably installed in the corresponding sliding groove 611. Both ends of each sliding groove 611 extend 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.

[0062] A plurality of reset springs 65 are provided. One end of each reset 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. In the normal state, the reset springs 65 force a part of the movable ring 63 to be exposed outside the linkage sleeve 61; the linkage blocks 64 are fixedly installed on the surface of the linkage ring 62 close to the linkage sleeve 61. In this embodiment, a plurality of linkage blocks 64 are provided, and the plurality of linkage blocks 64 are arranged at intervals around the central axis of the linkage ring 62, and the number of the linkage blocks 64 is correspondingly set with the number of the sliding blocks 631 of the movable ring 63. When a part of the movable ring 63 is exposed outside the linkage sleeve 61, the plurality of linkage blocks 64 and the plurality of sliding blocks 631 are arranged in a staggered manner around the central axis of the rotating shaft 11 (that is, the linkage blocks 64 are embedded between two adjacent sliding blocks 631).

[0063] Each of the linkage blocks 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 makes the movable ring 63 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 connection between the linkage ring 62 and the linkage sleeve 61 is disengaged.

[0064] Referring to 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, and the plurality of driven gears 72 are correspondingly arranged with the plurality of rotating discs 25. Each driven gear 72 is coaxially fixed to the outer peripheral wall of the corresponding rotating disc 25. The driving gear 71 and the plurality of driven gears 72 are both located on the side of the conveying turntable 2 away from the linkage sleeve 61; each driven gear 72 is provided with an avoidance notch 721, and the avoidance notch 721 is used to avoid steel materials so that the steel materials can enter and exit the docking groove 24 of the rotating disc 25.

[0065] A plurality of connecting gears 73 are rotatably installed on the surface of the conveying turntable 2 away from the linkage sleeve 61. The plurality of rotating discs 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 meshes and drives with the driven gears 72 of two adjacent rotating discs 25; a plurality of reversing gears 74 are rotatably installed 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 meshes and drives with the corresponding connecting gear 73 and meshes and drives with the driving gear 71; the arrangement of the reversing gears 74 and the connecting gears 73 enables the driving gear 71 and all the driven gears 72 to be in meshing transmission.

[0066] Specifically, in this embodiment, the setting of the reversing gear 74 enables the rotation direction of the rotating disk 25 to be consistent with the forward rotation direction of the rotating shaft 11 when the rotating disk 25 rotates on its own axis. With such a design, when the rotating disk 25 is located at the loading station 21 and rotates on its own axis, the steel in the rotating disk 25 is not likely to fall off, improving the connection stability between the rotating disk 25 and the steel.

[0067] Referring to Figure 4 、 Figure 8 , a plurality of limiting plates 14 are fixedly installed on the mounting frame 1. The plurality of limiting plates 14 are arranged corresponding to the plurality of conveying rotating disks 2. A limiting component 8 is arranged between each limiting plate 14 and the linkage sleeve 61 of the corresponding conveying rotating disk 2. When the rotating shaft 11 rotates in the reverse direction, the limiting component 8 stops the rotation of the linkage sleeve 61.

[0068] In this embodiment, the limiting component 8 includes a limiting ratchet 81, a limiting pawl 82 and a torsion spring. The limiting ratchet 81 is coaxially fixed on the outer peripheral wall of the linkage sleeve 61. 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 engage into the tooth groove of the limiting ratchet 81. To improve the limiting effect, the number of the limiting pawls 82 can be set to be multiple. With such a design, the cooperation between the limiting ratchet 81 and the limiting pawl 82 enables the conveying rotating disk 2 to only rotate forward along with the rotating shaft 11 and cannot rotate in the reverse direction along with the rotating shaft 11.

[0069] The implementation principle of Embodiment 2 of this 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 rotating disk 2 from the loading station 21, it forces the rotating shaft 11 to rotate in the reverse direction, driving the rotating disk 25 to rotate half a turn on its own axis. The rotating disk 25 can transfer the steel into the rotating groove 26, so that the inner walls of the docking groove 24 and the rotating groove 26 can jointly limit the short steel, improving the connection stability between the steel and the rotating disk 25.

[0070] Then, the rotating shaft 11 is driven to rotate forward, forcing this rotating disk 25 to transfer to the welding station 22 for welding. During the welding process, the rotating shaft 11 is driven to rotate in the reverse direction, so that the rotating disk 25 located at the welding station 22 can rotate on its own axis, driving the steel in the welding station 22 to rotate, so as to facilitate the welding torch 42 to weld the short steel in the welding station 22 in all directions. The cooperation between the robotic arm 41 and the rotating disk 25 greatly reduces the swinging amplitude of the robotic arm 41 (that is, the robotic 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 robotic arm 41.

[0071] After welding is completed, drive the rotating shaft 11 to rotate forward, forcing the long steel material after welding to be transferred to the blanking station 23. At this time, the next group of short steel materials to be welded are sent into the rotating disk 25 at the loading station 21 through the loading push bar 31, and the long steel material on the rotating disk 25 at the blanking station 23 can be pushed out synchronously, improving the operation convenience of the overall structure.

[0072] Embodiment 3

[0073] The embodiment of the present application discloses a welding device for steel processing.

[0074] Referring to Figure 9 、 Figure 10 The difference between the welding device for steel processing disclosed in the embodiment of the present application and Embodiment 2 is that:

[0075] In this embodiment, the top wall of the limiting plate 14 has an arc surface 141, the arc surface 141 abuts against the outer peripheral wall of the linkage sleeve 61, and a limiting groove 142 is formed in the arc surface 141; the limiting component 8 includes a limiting post 83 and a limiting spring 84. The limiting post 83 is arranged in the limiting groove 142. The inner wall of the limiting groove 142 has a guiding surface 143. The guiding surface 143 has a first side position 144 and a second side position 145. 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.

[0076] One end of the limiting spring 84 is fixedly connected to the limiting post 83, and the other end is fixedly connected to the inner wall of the limiting groove 142. The limiting spring 84 forces the limiting post 83 to move towards the second side position 145, and at the same time abuts against the guiding 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 rotating disk 2 drives the limiting post 83 to move towards the first side position 144. When the rotating shaft 11 rotates reversely, the outer peripheral wall of the rotating and conveying linkage sleeve 61 drives the limiting post 83 to move towards the second side position 145.

[0077] The implementation principle of Embodiment 3 of this application is as follows: 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 limit post 83 towards the first side position 144, so that the conveying turntable 2 can rotate forward following the rotating shaft 11 (that is, the conveying turntable 2 can transfer steel). When the rotating shaft 11 rotates reversely to drive the rotating disk 25 to rotate self, the conveying turntable 2 has a tendency to rotate reversely under the action of the guiding 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 limit post 83 towards the second side position 145, forcing the limit post 83 to abut against both the guiding surface 143 and the outer peripheral wall of the linkage sleeve 61 simultaneously. The friction between the linkage sleeve 61 and the limit plate 14 increases, so that the conveying turntable 2 cannot rotate reversely following the rotating shaft 11, achieving the anti-rotation effect on the conveying turntable 2, reducing the possibility that the conveying turntable 2 rotates reversely following the rotating shaft 11 when the rotating shaft 11 rotates reversely, and improving the stability of the overall structure.

[0078] The above are the preferred embodiments of this application. It does not limit the protection scope of this application accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of this application shall be covered within the protection scope of this application.
