DETAILED DESCRIPTION

[0029] In order to further understand the content, features and effects of the present invention, the following embodiments are given as examples and described in detail with reference to the accompanying drawings.

[0030] The structure of the present invention is described in detail below in conjunction with the accompanying drawings.

[0031] like Figures 1 to 11 As shown, an embodiment of the present invention provides a steel bar skeleton welding device for connecting assembled composite plates, including a box body 1, in which a first steel bar 5 and a second steel bar 6 to be welded are arranged, a supporting mechanism 4 is arranged on the inner side of the box body 1, the supporting mechanism 4 includes a first supporting assembly 41 and a second supporting assembly 42, the first steel bar 5 is inserted into the first supporting assembly 41, the second steel bar 6 is rollingly arranged on the second supporting assembly 42, a feeding mechanism 2 is arranged on the upper part of the second steel bar 6, the feeding mechanism 2 includes a material shifting assembly 21, a cleaning assembly 22, a first motor 23 and a rotating shaft 24, the output end of the first motor 23 is fixedly connected to the rotating shaft 24, the material shifting assembly 21 and the cleaning assembly 22 are fixedly sleeved on the rotating shaft 24, a welding mechanism 3 is arranged on the upper part of the box body 1, and the welding mechanism 3 includes two welding heads 36 that can be moved left and right and are symmetrically arranged on both sides of the first steel bar 5 to be welded.

[0032] Furthermore, the first supporting assembly 41 includes a fixing rod 412 fixedly connected to the two inner sides of the box body 1, and both ends of the fixing rod 412 are fixedly connected to the box body 1 through fixing plates 411 respectively. A plurality of sliders 413 are slidably connected to the fixing rod 412, and limiting grooves 4131 and clamping grooves 4132 are respectively provided on both sides of the sliders 413. The lower part of the first steel bar 5 is inserted into the clamping groove 4132, and one end of the fixing plate 411 and the fixing rod 412 are both slidably connected to the inner wall of the limiting groove 4131.

[0033] Specifically, one side of the fixing plate 411 is fixedly connected to the box body 1, and the other side is fixedly connected to the fixing rod 412. The slider 413 can slide along the fixing rod 412 driven by the first steel bar 5. When passing through the fixing plate 411, the slider 413 can slide through the connection between the fixing plate 411 and the fixing rod 412 through the opening of one end of the limiting groove 4131, so as to avoid the fixing plate 411 from hindering the movement of the slider 413. The clamping groove 4132 is used to clamp the first steel bar 5 to fix the first steel bar 5.

[0034] When in use, a number of first steel bars 5 are sleeved on the second steel bars 6, and then the two sides are respectively clamped into the clamping grooves 4132 on both sides, so that the first steel bars 5 stand up, which is convenient for subsequent welding work. Then, the first steel bars 5 are pushed forward in turn by the material shifting assembly 21, and the first steel bars 5 drive the slider 413 to move synchronously. Through the sliding cooperation between the slider 413 and the fixed rod 412, the overall stability of the first steel bars 5 is improved to ensure that they are always in contact with the second steel bars 6.

[0035] Furthermore, the second support assembly 42 includes a base frame 421 and a mounting rod 422. The lower end of the base frame 421 is fixedly connected to one side of the box body 1, and the upper end is fixedly connected to the mounting rod 422. The middle part of the mounting rod 422 is rotatably connected to an I-shaped wheel 423, and both ends are fixedly connected to arc-shaped support plates 424. The middle second steel bar 6 is rollingly connected to the middle part of the I-shaped wheel 423, and the second steel bars 6 on both sides are slidably connected to the arc-shaped support plates 424.

[0036] Specifically, three second steel bars 6 are provided, the middle second steel bars 6 are located on the I-wheel 423, and the second steel bars 6 on both sides are located in the arc-shaped support piece 424. The second steel bars 6 are supported and limited by the I-wheel 423 and the arc-shaped support piece 424. It should be noted that the friction between the second steel bar 6 and the arc-shaped support piece 424 is greater than the friction between the first steel bar 5 and the second steel bar 6, so as to ensure that the second steel bar 6 will not be displaced during the movement of the first steel bar 5 on the second steel bar 6. When the first steel bar 5 and the second steel bar 6 are welded together, the movement of the first steel bar 5 will drive the second steel bar 6 to move synchronously, which can realize the automatic transmission of the steel bars after welding and the change of the welding position, and facilitate the welding work of the next welding point.

[0037] Furthermore, the first motor 23 is fixedly installed on one side of the box body 1, and one end of the rotating shaft 24 away from the first motor 23 is rotatably connected to the other side of the box body 1. The material picking assembly 21 and the cleaning assembly 22 respectively include a first mounting frame 211 and a second mounting frame 221. The first mounting frame 211 and the second mounting frame 221 are both fixedly sleeved on the rotating shaft 24. A limiting rod 213 is fixedly connected inside the first mounting frame 211, and a paddle 212 is slidably sleeved on the limiting rod 213. The paddle 212 is slidably connected to the inner wall of the first mounting frame 211. A first spring 214 is sleeved on the limiting rod 213, and both ends of the first spring 214 are fixedly connected to the side wall of the first mounting frame 211 and the paddle 212 respectively, and the inner side of the paddle 212 abuts against the first steel bar 5.

[0038] Specifically, two material-prying assemblies 21 are provided, and three cleaning assemblies 22 are provided. The position of the cleaning assembly 22 corresponds to the position of the second steel bar 6. The material-prying assembly 21 is provided between two adjacent cleaning assemblies 22. When the first motor 23 is working, it drives the rotating shaft 24 to rotate, so that the material-prying assembly 21 and the cleaning assembly 22 rotate synchronously. During the rotation of the material-prying assembly 21, the paddle 212 contacts the first steel bar 5. As the paddle 212 rotates, the first steel bar 5 is moved closer to the welding point. During this process, the paddle 212 gradually compresses the first spring 214 and moves toward the direction close to the rotating shaft 24. Through this arrangement, the pressure on the first steel bar 5 can be reduced, the smoothness of the operation process can be improved, and the first steel bar 5 can be quickly put into place.

[0039] Furthermore, a plurality of connecting sleeves 222 are provided on the circumferential sliding sleeve of the second mounting frame 221, and the connecting sleeve 222 is connected to the end of the second mounting frame 221 by a second spring 223. An arc-shaped cleaning plate 224 is fixedly connected to one end of the connecting sleeve 222 away from the second mounting frame 221, and the arc-shaped cleaning plate 224 abuts against the outer peripheral surface of the upper end of the second steel bar 6.

[0040] Specifically, the second mounting frame 221 rotates synchronously with the rotating shaft 24, and drives the arc cleaning plate 224 to rotate. The arc cleaning plate 224 is against the second steel bar 6. During the rotation process, the dust and debris in the contact part with the second steel bar 6 are cleaned up to ensure the cleanliness of the welding part and avoid the influence of dust and debris on welding. As the first steel bar 5 approaches the welding point, the arc cleaning plate 224 contacts the first steel bar 5 and compresses the second spring 223 inward. The reaction force of the second spring 223 makes the arc cleaning plate 224 against the first steel bar 5, so that the first steel bar 5 is tightly against the second steel bar 6, thereby improving the tightness of the first steel bar 5 and the second steel bar 6 during welding, thereby improving the welding quality and stability during welding.

[0041] Furthermore, the welding mechanism 3 also includes a second motor 31, a screw rod 32 and a guide rod 33. The second motor 31 is fixedly installed on one side of the upper end of the box body 1, the screw rod 32 is rotatably installed on one side inside the box body 1, and the guide rod 33 is fixedly installed on the other side inside the box body 1. The output end of the second motor 31 is fixedly connected to one end of the screw rod 32, a first movable frame 34 is threadedly connected to the screw rod 32, and a second movable frame 35 is slidably connected to the guide rod 33. The first movable frame 34 is fixedly connected to the upper end of the second movable frame 35, and two welding heads 36 are respectively fixedly connected to the side close to the lower end of the first movable frame 34 and the second movable frame 35. A support rod 37 is fixedly connected to the lower end of the second movable frame 35 and located on one side of the welding head 36. A stopper 38 is fixedly connected to one end of the support rod 37, and the stopper 38 abuts against one side of the first steel bar 5.

[0042] Specifically, in the initial state, the welding head 36 is located outside the first steel bar 5 and will not hinder the movement of the first steel bar 5. The stopper 38 is located on the forward trajectory of the first steel bar 5. The first steel bar 5 moves forward along the second steel bar 6 under the movement of the material-push assembly 21, and stops when it moves to the stopper 38. The stopper 38 can not only determine the position of the first steel bar 5 during welding, but also play a guiding role in the subsequent welding process, guiding the welding head 36 to move forward. The stopper 38 and the paddle 212 are respectively abutted on both sides of the first steel bar 5, and the arc-shaped cleaning plate 224 is crimped onto the first steel bar 5, which can further improve the stability of the first steel bar 5.

[0043] During welding, the second motor 31 is started to drive the screw rod 32 to rotate, and the first movable frame 34 drives the second movable frame 35 to move right at the same time through the threaded cooperation between the screw rod 32 and the first movable frame 34 and the sliding cooperation between the second movable frame 35 and the guide rod 33, so that the first movable frame 34 drives the second movable frame 35 to move right at the same time, thereby realizing synchronous welding on both sides and improving welding efficiency. When the welding is completed, the welding head 36 is reset, and then the material shifting assembly 21 is rotated to push the welded first steel bar 5 forward. Since the first steel bar 5 and the second steel bar 6 are welded together, the second steel bar 6 will move forward synchronously, and the next shifting piece 212 contacts the next unwelded first steel bar 5, shifting it forward, and repeating the above operation, thereby realizing automatic loading of the first steel bar 5 and automatic forward movement of the welding completion position, cooperating with the welding operation of the welding mechanism 3, and jointly completing the equidistant welding of multiple steel bars.

[0044] Working principle of the present invention:

[0045] When in use, place the second steel bar 6 on the I-shaped wheel 423 and the arc-shaped supporting piece 424, and put a number of first steel bars 5 on the second steel bars 6, and then respectively clamp the two sides of them into the clamping grooves 4132 on both sides, so that the first steel bar 5 stands up, the upper end contacts the second steel bar 6, and is located on the rotation track of the paddle 212, and then start the first motor 23 to drive the rotating shaft 24 to rotate, and the rotating shaft 24 drives the material-pickup assembly 21 and the cleaning assembly 22 to rotate synchronously. During the rotation of the material-pickup assembly 21, the paddle 212 contacts the first steel bar 5 and moves the first steel bar 5 forward until one side of the first steel bar 5 abuts against the block 38. During this process, the arc-shaped cleaning plate 224 rotates to clean the dust and debris in contact with the second steel bar 6. When the first steel bar 5 contacts the arc-shaped cleaning plate 224, the arc-shaped cleaning plate 2 24 compresses the second spring 223 inwardly, and the reaction force of the second spring 223 makes the arc cleaning plate 224 resist the first steel bar 5. The stop block 38, the paddle 212 and the arc cleaning plate 224 cooperate with each other to ensure the stability and tightness of the contact between the first steel bar 5 and the second steel bar 6. Then, the second motor 31 is started to drive the welding head 36 to move to the right, and the welding heads 36 on both sides are started to weld the first steel bar 5 and the second steel bar 6 at the same time, so as to achieve synchronous welding on both sides and improve the welding quality and efficiency. After welding, the second motor 31 drives the welding head 36 to reset, and the first motor 23 drives the material prying assembly 21 to continue to rotate, so as to push the welded first steel bar 5 and the second steel bar 6 forward, and gradually pry the unwelded first steel bar 5 to the welding point, and repeat the above operation until the equidistant welding of the entire steel skeleton is completed.

[0046] In summary, the steel bar skeleton welding equipment for connecting assembled composite plates is provided with a material-pickup assembly 21 and a cleaning assembly 22 on a rotating shaft 24, and the material-pickup assembly 21 and the cleaning assembly 22 are driven to rotate synchronously by the rotating shaft 24, the material-pickup assembly 21 brings the unwelded first steel bar 5 to the welding point, and the cleaning assembly 22 cleans the welding part of the second steel bar 6 to ensure the welding quality. When the first steel bar 5 moves to the welding point, the stopper 38, the paddle 212 and the arc-shaped cleaning plate 224 are respectively against the two sides and the top of the first steel bar 5, so as to improve the first steel bar 5 and the second steel bar. 6, thereby ensuring the stability and reliability of welding. By setting the stopper 38, not only can the first steel bar 5 be positioned, but also the debris on the first steel bar 5 can be removed during the movement to prevent the debris from reducing the welding quality. After one welding work is completed, the material shifting component 21 continues to rotate to push the welded first steel bar 5 to move, so that the second steel bar 6 moves forward synchronously, and at the same time, the subsequent unwelded first steel bar 5 is brought to the welding point, realizing the adjustment of the welding position and automatic feeding, making the entire working process smooth and continuous, and improving work efficiency.
