Description
Technical Field
[0001] This utility model relates to the field of pre-embedded bar processing technology, specifically to an automatic welding device for pre-embedded bars. Background Technology
[0002] Welding of embedded steel bars is a common construction method in building engineering. It is mainly used to firmly connect steel bars to embedded parts in concrete structures. Embedded bars can provide fixing points for subsequent equipment (such as elevators and pipe supports), ensuring the safety and stability of the equipment. In secondary construction such as building decoration and curtain wall installation, embedded bars serve as connectors, simplifying the construction process and improving efficiency. Embedded bars can enhance the ductility of the structure, absorb energy during earthquakes, and reduce the risk of structural collapse. By properly arranging embedded bars, concrete shrinkage deformation can be constrained, reducing the possibility of crack formation.
[0003] During the production and processing of embedded bars, cutting, bending, and welding are required. Welding is usually done manually, which is highly dependent on the operator's skill level, resulting in inconsistent welding quality. Furthermore, manual welding requires individual operation, and the welding speed is limited by the welder's skill level and physical strength, making it difficult to achieve large-scale, high-efficiency production. Therefore, an automatic welding equipment for embedded bars is proposed to solve the above-mentioned problems. Utility Model Content
[0004] This utility model aims to solve at least one of the technical problems existing in the prior art. To this end, this utility model proposes an automatic welding equipment for pre-embedded ribs, including a processing table, with a feeding robot installed on one side of the processing table. A chain conveyor is installed on the processing table, and multiple equidistant material support plates are installed on the chain conveying end of the chain conveyor. Fixing components for fixing the pre-embedded ribs are installed on the material support plates. A moving component is installed on the processing table to open the fixing components to facilitate the feeding of the pre-embedded ribs. A dual-axis moving platform is installed on the table surface, and a welding device is installed at the moving end of the dual-axis moving platform. A positioning component is installed on one side of the processing table surface to promote the closure of the opening of the pre-embedded rib for easy welding.
[0005] Furthermore, the fixing component includes a sleeve fixedly installed on one side surface of the support plate. The support plate has a clearance hole communicating with the sleeve. A sliding rod with a protrusion on its surface is slidably connected inside the sleeve. One end of the sliding rod is provided with a limit ring, and the other end is hinged with a gripper. There are two grippers, which are arranged opposite each other. A spring is sleeved on the outside of the sliding rod, and the two ends of the spring abut against the protrusion and the inner end of the sleeve, respectively. The support plate is rotatably connected to a rotating shaft, and a limit plate is provided between the rotating shaft and an adjacent gripper.
[0006] Furthermore, two symmetrically arranged guide blocks are fixedly installed on the surface of the support plate, and the surfaces of the two guide blocks on opposite sides are inclined. The surface of the support plate is provided with positioning blocks.
[0007] Furthermore, it includes a clamping assembly for bonding the embedded rib to the surface of the support plate. The clamping assembly includes a first one-way cylinder arranged vertically. The telescopic end of the first one-way cylinder is provided with a connecting plate. The end of the connecting plate away from the first one-way cylinder is provided with a threaded rod, and one end of the threaded rod is provided with a pressure plate.
[0008] Furthermore, the processing table surface is provided with a number of mounting seats that are equidistantly distributed, and the top and side surfaces of the mounting seats are respectively rotatably connected to a first rolling bearing and a second rolling bearing.
[0009] Furthermore, the moving component includes a telescopic cylinder fixedly installed on the processing table. The telescopic end of the telescopic cylinder is provided with a connecting block. Both sides of the connecting block are provided with clamping blocks arranged symmetrically. A cavity adapted to the limiting ring is opened between the two clamping blocks.
[0010] Furthermore, the dual-axis moving platform includes a vertical moving platform fixedly installed on the processing table surface, a horizontal moving platform is provided at the moving end of the vertical moving platform, and a welding device is provided at the moving end of the horizontal moving platform.
[0011] Furthermore, the positioning assembly includes a second one-way cylinder and a third one-way cylinder fixedly installed on the processing table surface. The extension end of the second one-way cylinder is provided with a push plate that is at the same level as the positioning block, and the extension end of the third one-way cylinder is provided with an L-shaped plate.
[0012] The beneficial effects of this utility model are as follows: By setting up a chain conveyor and a feeding robot, this utility model realizes continuous conveying and automatic feeding of pre-embedded ribs. The support plate is equipped with a fixed component, which works in conjunction with the moving component to accurately fix the pre-embedded ribs, ensuring that the pre-embedded ribs have good opening and closing during the welding process, which facilitates subsequent welding processing. The welding equipment completes welding efficiently under the drive of a dual-axis moving platform, significantly shortening the processing time of a single piece and greatly improving production efficiency. Compared with existing technologies, it eliminates quality fluctuations caused by differences in technical level in manual welding, resulting in uniform welds, reducing defects such as porosity and cracks, and reducing manual handling, positioning, and welding operations, thereby reducing the labor intensity and cost of workers, making it suitable for large-scale production scenarios.

[0024] In the embodiments, by Figure 1-7 Provided is an automatic welding device for embedded ribs, comprising a processing table 1, with a feeding robot 2 mounted on one side of the processing table 1, a chain conveyor 3 mounted on the processing table 1, multiple equidistantly distributed support plates 4 mounted on the chain conveyor end of the chain conveyor 3, and fixing components 5 for fixing the embedded ribs mounted on the support plates 4, a moving component 6 mounted on the processing table 1 for opening the fixing components 5 to facilitate feeding the embedded ribs, a dual-axis moving platform 7 mounted on the table surface of the processing table 1, and a welding device 8 mounted on the moving end of the dual-axis moving platform 7, and a positioning component 9 located on one side of the processing table 1 for promoting the closure of the opening of the embedded rib to facilitate welding. Before loading, the moving component 6 is activated to open the fixing component 5 in the support plate 4 at the loading position, facilitating the loading of the embedded ribs. The loading robot 2 automatically loads the embedded ribs onto the current support plate 4. Then, the moving component 6 is reset, and the fixing component 5 automatically fixes the embedded ribs to the surface of the support plate 4. The chain conveyor 3 is started, driving the support plate 4 and the embedded ribs on it forward. When it moves to the processing position, the positioning component 9 is activated to promote the closure of the opening of the embedded ribs, preparing for welding. Then, the welding equipment 8 performs welding operations on the embedded ribs under the drive of the dual-axis moving platform 7. After welding is completed, the chain conveyor 3 continues to transport the support plate 4 and the welded embedded ribs on it to the unloading position for retrieval.
[0025] Reference Figure 1-7The fixing component 5 includes a sleeve 51 fixedly installed on one side surface of the support plate 4. The support plate 4 has a clearance hole 52 that communicates with the sleeve 51. A sliding rod 53 with a protrusion on its surface is slidably connected inside the sleeve 51. One end of the sliding rod 53 is provided with a limit ring 54, and the other end is hinged with a claw 55. There are two claws 55, which are arranged opposite to each other. A spring 56 is sleeved on the outside of the sliding rod 53. The two ends of the spring 56 abut against the protrusion and the inner end of the sleeve 51, respectively. A rotating shaft 57 is rotatably connected to the surface of the support plate 4. A limit plate 58 is provided between the rotating shaft 57 and an adjacent claw 55.
[0026] With the above structural setup, in the initial state, the spring 56 is in a compressed state, applying elastic force to the slide rod 53, causing the slide rod 53 to slide into the sleeve 51, while simultaneously driving the gripper 55 to move towards the surface of the support plate 4. The gripper 55 is in a closed state. When it is necessary to fix the embedded rib, the moving component 6 drives the slide rod 53 to move, overcoming the elastic force of the spring 56, and driving the gripper 55 to move away from the surface of the support plate 4. The gripper 55 is in an open state, which facilitates the loading or unloading of the embedded rib. After the embedded rib is placed in place, the external operation is released, and the slide rod 53 slides into the sleeve 51 under the elastic force of the spring 56, driving the gripper 55 to return to the closed state.
[0027] Reference Figure 1-7 The material support plate 4 has two symmetrically arranged guide blocks 10 fixedly installed on its surface, and the two guide blocks 10 have an inclined surface on one side of their opposite side. The material support plate 4 is provided with a positioning block 11.
[0028] With the above structural design, when the embedded bar is placed on the support plate 4, the inclined surface design of the guide block 10 can guide the embedded bar to move along the inclined surface direction, so that the embedded bar can be accurately placed in the predetermined position on the support plate 4. During the placement of the embedded bar, the positioning block 11 serves as a reference point to ensure that one end or a specific part of the embedded bar is in contact with or aligned with the positioning block 11, thereby ensuring that the embedded bar is accurately positioned on the support plate 4.
[0029] Reference Figure 1-7 The device includes a pressing assembly 12 for attaching the embedded rib to the surface of the support plate 4. The pressing assembly 12 includes a first one-way cylinder 121 arranged vertically. The telescopic end of the first one-way cylinder 121 is provided with a connecting plate 122. The end of the connecting plate 122 away from the first one-way cylinder 121 is provided with a threaded rod 123, and the end of the threaded rod 123 is provided with a pressure plate 124.
[0030] With the above structural setup, after the embedded rib is placed on the support plate 4, the first one-way cylinder 121 is activated to control the pressure plate 124 to press the embedded rib onto the support plate 4, thereby achieving the fit between the embedded rib and the surface of the support plate 4. The threaded rod 123 is connected to a locking nut on the outer thread. By adjusting the height of the threaded rod 123, the position of the pressure plate 124 can be adjusted, thereby adjusting the magnitude of the clamping force to ensure that the embedded rib is properly clamped.
[0031] Reference Figure 1-7 The table surface of the processing table 1 is provided with several mounting seats 13 that are equidistantly distributed. The top and one side surfaces of the mounting seats 13 are respectively rotatably connected to a first rolling bearing 14 and a second rolling bearing 15.
[0032] With the above structural arrangement, the mounting base 13 serves as a support point, providing a stable mounting position for the first rolling bearing 14 and the second rolling bearing 15. The first rolling bearing 14 and the second rolling bearing 15, through their rolling characteristics, provide low-friction support and guidance for the material support plate 4, enabling it to move smoothly. Furthermore, the first rolling bearing 14 and the second rolling bearing 15 contact the bottom end face and the side face of the material support plate 4, respectively, further reducing friction.
[0033] Reference Figure 1-7 The moving component 6 includes a telescopic cylinder 61 fixedly installed on the processing table 1. The telescopic end of the telescopic cylinder 61 is provided with a connecting block 62. Both sides of the connecting block 62 are provided with clamping blocks 63 arranged symmetrically. A cavity 64 for the limiting ring 54 is opened between the two clamping blocks 63.
[0034] With the above structural setup, when the fixing component 5 needs to be opened, the slide rod 53 falls into the cavity 64 between the two clamping blocks 63. Then, the telescopic cylinder 61 drives the clamping blocks 63 to move. When the clamping blocks 63 contact the limiting ring 54, the cylinder continues to extend. Through the interaction between the clamping blocks 63 and the limiting ring 54, the slide rod 53 is driven to slide out of the sleeve 51, overcoming the elastic force of the spring 56, so that the gripper 55 opens, thereby opening the fixing component 5. There are two fixing components 5, which are located at the loading and unloading positions respectively, which facilitates the loading and unloading of the pre-embedded ribs.
[0035] Reference Figure 1-7 The dual-axis moving platform 7 includes a vertical moving platform 71 fixedly installed on the table surface of the processing table 1, and a horizontal moving platform 72 is provided at the moving end of the vertical moving platform 71. A welding device 8 is provided at the moving end of the horizontal moving platform 72.
[0036] With the above-described structure, the vertical moving platform 71 and the horizontal moving platform 72 adopt existing technology and can be purchased directly from the market. Their principle is the same as that of the electric slide table, so it will not be described again. Through the cooperation of the vertical moving platform 71 and the horizontal moving platform 72, the welding equipment 8 can be moved to facilitate welding processing.
[0037] Reference Figure 1-7 The positioning component 9 includes a second one-way cylinder 91 and a third one-way cylinder 92 fixedly installed on the table surface of the processing table 1. The extension end of the second one-way cylinder 91 is provided with a push plate 93 that is at the same level as the positioning block 11, and the extension end of the third one-way cylinder 92 is provided with an L-shaped plate 94.
[0038] With the above structural setup, in the initial state, both the second one-way cylinder 91 and the third one-way cylinder 92 are in a retracted state, and the push plate 93 and the L-shaped plate 94 are located away from the pre-embedded rib to avoid interference with the transportation of the pre-embedded rib. Before welding, the second one-way cylinder 91 and the third one-way cylinder 92 are activated in sequence. The second one-way cylinder 91 pushes the push plate 93 to move towards the pre-embedded rib until one end of the pre-embedded rib contacts the positioning block 11, thereby positioning the pre-embedded rib in the horizontal direction and closing the opening of the pre-embedded rib. The third one-way cylinder 92 pushes the L-shaped plate 94 to move towards the pre-embedded rib to block and position the pre-embedded rib, ensuring the accurate position of the pre-embedded rib in the vertical direction and ensuring the consistency of the welding position.
[0039] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus.
