Description

Technical Field

[0001] The invention relates to the technical field of stud welding, in particular to a stud welding machine based on laying of steel bar truss floor decks. Background Art

[0002] Steel truss floor deck is a composite structural system formed by processing the main load-bearing steel bars in the floor slab into steel trusses using special equipment in the factory, and then welding the steel trusses and galvanized steel plates into one. During the construction stage of the structural floor slab, the system uses galvanized steel plates to replace the construction formwork, and the truss structure formed by the welded steel bars in the structure bears the self-weight of the floor slab concrete and the construction load together. Steel truss floor deck has the advantages of economy, safety, reliability, and fast construction speed, so it has been widely used in modern buildings. In the laying process of steel truss floor deck, stud welding is a key link. As a shear-resistant connector connecting the steel beam and the floor deck, the welding quality of the stud directly affects the overall performance and safety of the floor slab. Traditional stud welding methods mostly use manual arc welding, which has problems such as low welding efficiency, unstable quality, and difficult operation. With the development of industrial automation technology, the application of automatic welding machines for steel trusses is becoming more and more common. This welding machine uses the arc generated by the welding power supply to weld the components of the steel truss, and has the advantages of high welding efficiency, stable quality, and easy operation.

[0003] For example, the patent application with the prior art publication number CN116652432A provides a stud welding device and a stud welding method, the stud welding device includes a mechanical arm, a connection seat, a rotating drive device, a nail plate, a lifting drive device, a welding gun device and a control device, the rear side of the connection seat is connected to the mechanical arm, the rotating drive device and the lifting drive device are both arranged on the front side of the connection seat, the nail plate is connected to the driving end of the rotating drive device, the nail plate has a plurality of placement positions evenly distributed around the rotation axis, and an avoidance space is formed between two adjacent placement positions, the welding gun device is arranged at the driving end of the lifting drive device and can pass through the avoidance space. The stud welding device and the stud welding method of the present invention can realize continuous and automatic welding action, without the need for operators to manually weld each stud, effectively reducing the labor intensity of the staff, avoiding physical strain of the workers, and effectively improving the efficiency of the welding operation.

[0004] Although the above-mentioned prior art realizes the storage of bolts and the extraction of bolts by the welding gun device by setting a nail plate, thereby improving the welding efficiency to a certain extent, its limitations are fully revealed when facing large-scale projects such as steel truss floor decking. Specifically, such projects often require the welding of tens of thousands of bolts, and the nail plate of the prior art needs to replenish the bolts in the clamping holes after the bolts are consumed. This step is not only cumbersome and time-consuming, but also in continuous high-intensity operations, the speed of replenishing bolts is often difficult to keep up with the working rhythm of the welding gun device, resulting in a decrease in production efficiency. What is more serious is that the welding work may also be suspended due to untimely replenishment of bolts, further affecting the progress and quality of the project. Therefore, when facing a steel truss floor decking project that requires welding a large number of bolts, the prior art method of manually replenishing bolts with a nail plate is obviously unable to meet the requirements of continuity and efficiency. To this end, the present application proposes a bolt welding machine based on the laying of steel truss floor decking. Summary of the invention

DETAILED DESCRIPTION

[0035] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0036] Example 1: Please refer to Figure 1 , Figure 2 as well as Figure 3The present invention provides a technical solution: a stud welding machine based on the laying of steel truss floor decking, comprising a cross frame 100 and a stud gun welding machine 102, both ends of the cross frame 100 are bolted with mounting legs 101 for supporting it, the mounting legs 101 can be set to different heights to change the height of the cross frame 100, and the mounting legs 101 and the cross frame 100 are connected by bolts in a detachable manner to improve the disassembly and assembly efficiency and facilitate transportation, a steel truss floor decking 500 is arranged below the cross frame 100, and a swivel 200 for fixing the stud gun welding machine 102 is arranged on the outer surface of the cross frame 100, and a screw block 203 is slidably connected inside the cross frame 100, and the ... The bottom of the cross frame 100 is slidably connected with the swivel 200. A driving assembly for driving the screw block 203 to move is arranged inside the cross frame 100. By setting the driving assembly, the position of the swivel 200 can be changed so as to facilitate the adjustment of the stud gun welder 102, thereby realizing continuous stud welding. Both sides of the cross frame 100 are provided with slide bars 210 for the swivel 200 to slide. The top of the cross frame 100 is provided with a transmission assembly for driving the slide bar 210 to rotate. By setting the transmission assembly, the position of the stud gun welder 102 can be adjusted so as to facilitate the delivery of the studs to the inside for fixing. By setting the height-adjustable mounting legs 101, the device can adapt to different working environments and requirements. The height of the mounting legs 101 can be adjusted according to actual needs, so that the cross frame 100 and the stud gun welder 102 thereon can reach the ideal operating height. The mounting legs 101 are connected to the cross frame 100 by bolts. This detachable design not only improves the disassembly and assembly efficiency, but also makes the entire device more convenient during transportation. By disassembling the mounting legs 101, the volume and weight of the device can be significantly reduced, making it easier to carry and store.

[0037] For further information, see Figure 3 , Figure 4 as well as Figure 5 The driving assembly includes a driving motor 201 fixedly connected to the inside of the cross frame 100, and the output end of the driving motor 201 is fixedly connected to a screw rod 202, and a screw block 203 is threadedly connected to the outer surface of the screw rod 202. The screw block 203 cooperates with the inside of the cross frame 100 so that the screw rod 202 can effectively drive the screw block 203 to move. At the same time, the screw block 203 is slidably connected to the swivel 200 to drive it to move without affecting its rotation.

[0038] Furthermore, the transmission assembly includes two top frames 204 fixedly connected to the top of the cross frame 100, and the interiors of the two top frames 204 are slidably connected with arcs 205, and the two arcs 205 are commonly fixedly connected to two slide bars 210. A servo motor 209 is fixedly connected to one side of the top frame 204, and a rotating rod 207 is fixedly connected to the output end of the servo motor 209. The outer surface of the rotating rod 207 is fixedly connected to a gear 208, and the inner wall of the arc 205 is fixedly connected to a first tooth 206 meshing with the gear 208. At the same time, the slide bar 210 is arranged to guide the swivel 200, and the cooperation of the gear 208 and the first tooth 206 can effectively drive the arc 205 to rotate, thereby driving the slide bar 210 to move, and then driving the swivel 200 to rotate with it, thereby changing the orientation position of the stud gun welder 102. Under the cooperation of the driving assembly and the transmission assembly, the position and angle of the stud gun welder 102 can be adjusted, and the cooperation between the two will not interfere with each other.

[0039] Specifically, the mounting leg 101 is fixed to the ground and then the cross frame 100 is mounted on the mounting leg 101. Then, the driving motor 201 is started to drive the screw rod 202 to rotate so that the screw block 203 moves inside the cross frame 100, so that the screw block 203 drives the swivel 200 to slide on the surface of the slide bar 210, thereby changing the position of the stud gun welder 102, and at the same time, the ceramic ring is placed at the required position, and then the stud gun welder 102 is operated to pass the stud through the magnetic ring and weld it with the steel truss floor deck 500. The stud welding machine is mainly composed of the cross frame 100, the stud gun welder 102 and the mounting leg 101 with adjustable height. As the main structure of the equipment, the cross frame 100 not only carries the stud gun welder 102, but also realizes the precise adjustment of the position and angle of the stud gun welder 102 through the driving assembly and transmission assembly arranged inside it. Through the mutual cooperation of the driving assembly and the transmission assembly, the precise adjustment of the position and angle of the stud gun welder 102 is realized, which greatly improves the construction efficiency.

[0040] It is worth mentioning that the driving assembly and the transmission assembly cooperate with each other to operate the swivel 200 to move or rotate in a smaller space as possible, and the close cooperation between the various components can effectively achieve flexible regulation.

[0041] In summary, by setting the driving assembly, the position of the swivel 200 can be precisely controlled, and then the position of the stud gun welder 102 can be precisely adjusted. This precision ensures that the studs can be accurately welded to the steel truss floor deck 500, improving the welding quality and the stability of the overall structure. By setting the transmission assembly, the swivel 200 can be rotated, thereby changing the orientation of the stud gun welder 102. This multi-angle welding capability greatly expands the scope of application of the device, allowing it to adapt to welding requirements in different directions and angles, improving the flexibility and efficiency of the operation, and by precisely controlling the position and angle of the stud gun welder 102, the device can achieve continuous stud welding, reducing waiting time and manual intervention, and improving overall operation efficiency. This is particularly important for projects that require large-scale welding operations, and can significantly shorten the construction period.

[0042] Example 2: Please refer to Figure 3 , Figure 6 as well as Fig.11 The present invention also provides a technical solution, which is different from the technical solution of the first embodiment: a stud welding machine based on the laying of steel truss floor decking, the interior of the swivel 200 is slidably connected with a positioning block 302 slidably connected to the cross frame 100, and one end of the positioning block 302 is fixedly connected to a connecting frame 303, and one end of the connecting frame 303 is fixedly connected to a loading shell 300, and a material distribution groove 304 is provided inside the loading shell 300, and a loading assembly is arranged inside the loading shell 300, and the positioning block 302 can move with the swivel 200 to change the position of the loading shell 300, so that the loading shell 300 is always located on the same axis as the stud gun welding machine 102, and the positioning block 302 is slidably connected to the cross frame 100 so that the position of the positioning block 302 will not be changed when the swivel 200 rotates. By arranging the loading assembly, the tediousness of manual operation can be reduced, the efficiency of loading can be improved, and automated work can be realized.

[0043] For further information, see Fig.12 , Fig.14 as well as Fig.15The feeding assembly includes a feeding slide plate 307 slidably connected to the feeding trough 304, a roller 305 is rotatably connected to the inside of the feeding shell 300, and a plurality of feeding grooves 306 are evenly arranged on the outer surface of the roller 305. The top of the feeding shell 300 is fixedly connected to the feeding port 301, and one end of the feeding shell 300 is rotatably connected to a ratchet 412 fixedly connected to the roller 305, and one end of the feeding shell 300 is provided with a rotating disk 408 rotatably connected to the rack 402, and the inner wall of the rotating disk 408 is rotatably connected to a plurality of ratchet claws 412 adapted to the ratchet 412. 0, the inner wall of the turntable 408 is fixedly connected with a tension spring 411 fixedly connected to the ratchet 410, and the ejection slide plate 307 can store force to push the studs in the batching trough 304 into the stud gun welding machine 102, and the roller 305 can effectively separate multiple studs so that they fall into the feed trough 306 in the order of installation, avoiding multiple studs from entering the batching trough 304 and affecting the feeding, and the mutual cooperation of the turntable 408 and the ratchet 412 can realize the intermittent transmission of the roller 305, ensuring the mutual cooperation between the ejection slide plate 307 and the roller 305.

[0044] For further information, see Figure 7 , Figure 8 as well as Fig. 9 The outer surface of the turntable 408 is fixedly connected with a handle 409, and the bottom of the positioning block 302 is slidably connected with a rack 402. The outer surface of the swivel 200 is fixedly connected with a second tooth 403 meshing with the rack 402. A gas cylinder 400 is fixedly connected to one side of the connecting frame 303, and a piston rod 401 adapted to the gas cylinder 400 is fixedly connected to one end of the rack 402. A gas receiving cylinder 405 is fixedly connected to one side of the feeding shell 300. The gas receiving cylinder 405 is connected to the gas cylinder 400 through an air pipe 404. The bottom of the gas receiving cylinder 405 is slidably connected with a driven piston rod 406 adapted thereto, and the bottom of the driven piston rod 406 is fixedly connected with a push handle 407 rotatably connected to the handle 409. By setting the cooperation between the swivel 200 and the transmission assembly, the second tooth 403 of Shudie cooperates with the rack 402 to start the feeding assembly to work, and the rotation and resetting of the swivel 200 is a process.

[0045] Among them, see Fig. 9 , Fig.10 as well as Fig.13The end of the ejecting slide 307 away from the dispensing groove 304 is fixedly connected to a limit block, and the top of the limit block is rotatably connected to a crank 309. The outer surface of the ejecting slide 307 is sleeved with a reset spring 308 for its own reset. The outer surface of the turntable 408 is provided with a transmission groove 413, and the top of the crank 309 is rotatably connected to a ball 415 slidably connected to the transmission groove 413. The transmission groove 413 is internally rotatably connected to a block 414. When the pawl 410 is idling, it will drive the ball 415 to move in the transmission groove 413, and then the transmission crank 309 will tilt and pull the ejecting slide 307 to move for accumulating force. When the turntable 408 is about to rotate to the limit position, it will quickly reset and release the ejecting slide 307 to complete the loading. Subsequently, the rotation of the turntable 408 will cause the ball 415 to resist the block 414 and reset. The block 414 is a one-way block, and the ball 415 can be reset by the block 414.

[0046] It is worth mentioning that the bolt gun welder 102 is a prior art which can quickly fix the bolt by contacting it. The reset spring 308 is stretched by the top material slide plate 307 and then quickly reset under the action of the reset spring 308, thereby pushing the bolt in the material trough 304 to move quickly and insert it into the bolt gun welder 102, thereby realizing the loading of the bolt. The mutual cooperation between the material assembly and the transmission assembly realizes the continuous loading and welding of the bolt, avoiding the tediousness and errors of manual operation. The equipment can adjust the height of the mounting legs according to actual needs, and adjust the position and angle of the bolt gun welder 102 through mechanical linkage, which is suitable for different working environments and needs.

[0047] Specifically, the servo motor 209 is turned on to drive the rotating rod 207 to rotate, thereby driving the gear 208 to rotate, so that the gear 208 meshes with the first tooth 206 to drive the arc 205 to move, and then the sliding rod 210 is pulled to rotate to drive the rotating ring 200 to rotate, thereby changing the angle of the stud gun welding machine 102 to make it face the loading shell 300. At the same time, when the rotating ring 200 is pulled by the sliding rod 210 to rotate, it will drive the second tooth 403 to mesh with the rack 402, thereby driving the piston rod 401 The rotating disc 408 rotates counterclockwise on the surface of the ratchet 412. At this time, the counterclockwise rotation of the rotating disc 408 drives the ratchet 410 to slide on the surface of the ratchet 412 and cannot engage with the ratchet 412. The counterclockwise rotation will drive the ball bearing 415 to slide on the surface of the transmission groove 413, thereby driving the crank 309 to tilt and pull the ejector slide 307 to move and accumulate force. When the turntable 408 continues to rotate, the ball bearing 415 will be reset in the transmission groove 413, thereby releasing the accumulated force of the ejector slide 307, so that the ejector slide 307 hits the stud in the batching groove 304 and pushes it into the stud gun welding machine 102. At this time, the stud gun welding machine 102 is driven to reset, so that the rack 402 is reset, thereby the air cylinder 408 is 05, the gas in the gas cylinder 400 is drawn back to the gas cylinder 400, thereby driving the handle 409 to reset and making the turntable 408 reset clockwise. At this time, the ball 415 will pass over the block 414 and reset, so as not to pull the crank 309 to tilt. At the same time, when the turntable 408 rotates clockwise, it will drive the pawl 410 to engage with the ratchet 412 and drive the roller 305 to rotate, thereby changing the position of the feed trough 306 so that the bolt inside it falls into the inside of the feeding trough 304, preparing for the next replenishment of the bolt gun welding machine 102.

[0048] In summary, through the design of the feeding component, the bolt can be automatically pushed from the material trough 304 to the bolt gun welding machine 102, which greatly reduces the tediousness of manual operation and improves the efficiency of feeding. The cooperation of the ejection slide plate 307 and the return spring 308 enables the bolt to be quickly and stably pushed to the welding position, ensuring the continuity and efficiency of the welding operation. Through the mechanical linkage of the turntable 408 and the rack 402, the piston rod 401, the air cylinder 405 and other components, the effective utilization and transmission of energy is realized, and unnecessary energy consumption is reduced. The cooperation of the ratchet 412 and the pawl 410 realizes the intermittent transmission of the turntable 408, so that the ejection slide plate 307 and the roller 305 can cooperate with each other, further improving the energy utilization efficiency.

[0049] Working principle: When in use, first fix the mounting leg 101 to the ground and then install the cross frame 100 on the mounting leg 101, then place the studs inside the feed port 301 for storage, then start the drive motor 201 to drive the screw rod 202 to rotate so that the screw block 203 moves inside the cross frame 100, so that the screw block 203 drives the rotating ring 200 to slide on the surface of the sliding rod 210, thereby changing the position of the stud gun welding machine 102, and at the same time, place the ceramic ring according to the required position;

[0050] When the stud gun welding machine 102 needs to be fed, the servo motor 209 is turned on to drive the rotating rod 207 to rotate, thereby driving the gear 208 to rotate, so that the gear 208 meshes with the first tooth 206 and drives the arc 205 to move, and then the sliding rod 210 is pulled to rotate to drive the rotating ring 200 to rotate, thereby changing the angle of the stud gun welding machine 102 to make it face the loading shell 300. At the same time, when the rotating ring 200 is pulled and rotated by the sliding rod 210, the second tooth 403 is driven to mesh with the rack 402, thereby driving the piston rod 401 to slide inside the gas cylinder 400, so that the gas in the gas receiving cylinder 405 is transported to the inside of the gas cylinder 400 through the air pipe 404, and when the gas in the gas receiving cylinder 405 becomes less, Pull the driven piston rod 406 to move so that the push handle 407 pulls the handle 409 to move, thereby driving the turntable 408 to rotate counterclockwise on the surface of the ratchet 412. At this time, the counterclockwise rotation of the turntable 408 will drive the pawl 410 to slide on the surface of the ratchet 412 and cannot be engaged with the ratchet 412. The counterclockwise rotation of the turntable 408 will drive the ball 415 to slide on the surface of the transmission groove 413, thereby driving the crank 309 to tilt and pull the ejection slide plate 307 to move and accumulate force. When the turntable 408 continues to rotate, the ball 415 will reset in the transmission groove 413, thereby releasing the accumulated force of the ejection slide plate 307, so that the ejection slide plate 307 hits the stud in the batching groove 304 and is pushed into the stud gun welding machine 102.

[0051] At this time, the stud gun welding machine 102 is driven to reset so that the rack 402 is reset, thereby sucking the gas in the gas receiving cylinder 405 back into the gas delivery cylinder 400, and then driving the handle 409 to reset so that the turntable 408 is reset clockwise. At this time, the ball 415 will pass over the block 414 and reset so as not to pull the crank 309 to tilt. At the same time, when the turntable 408 rotates clockwise, it will drive the pawl 410 to engage with the ratchet 412 and drive the roller 305 to rotate, thereby changing the position of the feed trough 306 so that the studs inside it fall into the inside of the feeding trough 304, preparing for the next replenishment of the stud gun welding machine 102.
