Description

Technical Field

[0001] This invention relates to the field of steel bar welding technology, and in particular to an automated welding equipment for prefabricated steel bars. Background Technology

[0002] Early steel bar prefabrication mainly relied on manual welding or semi-automated equipment, which had problems such as low efficiency, unstable quality, and labor intensity. Manual welding is prone to defects such as porosity and cracks, and it is difficult to meet the needs of large-scale production. Furthermore, for complex structures (such as steel cages and anti-fall beam blocks), traditional equipment requires multiple feeding and adjustments, which further reduces efficiency.

[0003] Currently, in order to adapt to the welding of steel bars with different requirements, manual adjustment is basically used. However, when switching between multiple specifications of steel bars, a single changeover takes more than 30 minutes under manual adjustment. The main reason is the lack of adaptive clamps (the positioning mold needs to be changed manually).

[0004] In the publicly available patent document CN115338537B, an automated laser welding equipment and method for reinforcing mesh are disclosed. This method solves the technical problem of ineffective welding caused by excessive lap gaps in the reinforcing mesh during automatic welding. The solution involves a moving crossbeam spanning above a translational track, a clamping auxiliary fixture installed on the moving crossbeam, and a lifting auxiliary fixture positioned below the worktable. When in operation, the lifting auxiliary fixture is located at the projection position directly below the clamping auxiliary fixture. This allows for effective clamping of the reinforcing mesh before welding using the lifting and clamping auxiliary fixtures, ensuring effective contact between the nodes to be welded. This provides assurance for the visual recognition and automatic welding processes of the reinforcing mesh.

[0005] When the above devices are in use, although the clamping auxiliary tooling can effectively clamp the steel mesh, there are a certain number of clamp rust and bending points on the surface of the steel bars during the transportation process. The existing methods are manual or tooling treatment. Manual treatment takes a long time, more than 30 minutes at a time. At the same time, the current tooling treatment cannot adapt to the uneven position of the steel bar surface, resulting in a certain gap at the clamping position, which cannot provide good clamping of the steel bars. In addition, since the clamps are not designed with an elastic compensation structure, hard contact can easily cause steel bar displacement.

[0006] Therefore, this application proposes an automated welding equipment for precast steel bars. Summary of the Invention

[0007] The purpose of this invention is to address the problem in the prior art that the surface of the reinforcing bars has a certain number of clamping corrosion and bending points during the transportation process, and that existing tooling cannot adapt to the uneven position of the reinforcing bar surface, resulting in a certain gap in the clamping position. The invention proposes an automated welding equipment for prefabricated reinforcing bars.

Multiple sets of first arc-shaped tubes are rotatably installed inside the arc-shaped fixing frame through a first arc-shaped groove. Multiple sets of second arc-shaped tubes are rotatably installed on one side of the multiple sets of first arc-shaped tubes through a second arc-shaped groove.

[0012] Optionally, the cleaning assembly, which is fixedly installed on one side of the rebar conveying frame for cleaning residual material from the surface of the adaptive clamping assembly, is provided with a laser welding assembly for rebar welding on one side of the rebar conveying frame.

[0013] Optionally, the rebar conveying assembly includes a first motor fixedly installed on one side of the rebar conveying frame. A drive gear is fixedly installed at one end of the output shaft of the first motor that passes through the rebar conveying frame. A driven gear is meshed with the outer side of the drive gear. Multiple conveying rods are rotatably installed on the side of the rebar conveying frame away from the first motor. The driven gear is fixedly installed on the outer side of one of the conveying rods. A matching sleeve is fixedly installed on the outer wall of the three conveying rods. A conveyor belt is rotatably installed on the three conveying rods through the matching sleeve.

[0014] Optionally, a wire feeding wheel with multiple wire feeding grooves is fixedly installed on the outer side of the transmission rod, and multiple spring telescopic rods are fixedly installed on one side of the wire feeding wheel, with a straightening ring fixedly installed on one side of each spring telescopic rod.

[0015] Optionally, the clamping and shifting assembly includes a guide rail frame fixedly installed on the top of the rebar conveying frame. A built-in threaded block is slidably installed inside the guide rail frame. A threaded rod is threaded inside the built-in threaded block. A second motor is provided on one side of the threaded rod. The second motor is fixedly installed on the top of the rebar conveying frame.

[0016] Optionally, an auxiliary rotating rod is rotatably mounted inside the built-in threaded block, and two sets of gears are fixedly mounted on the outer side of the auxiliary rotating rod.

[0017] Optionally, an H-guide frame is fixedly installed on the top of the built-in threaded block, and two sets of rack blocks are slidably installed inside the H-guide frame. The two sets of rack blocks are set in a meshing state with the gear, and the lower set of rack blocks is fixedly installed on one side of the arc-shaped fixed frame.

[0018] Optionally, a sliding cavity plate is fixedly installed on one side of the H-guide frame, a pressure sensor is fixedly installed inside the sliding cavity plate, an auxiliary spring is fixedly installed between the pressure sensor and the sliding cavity plate, and a pressure receiving component is slidably installed on one side of the H-guide frame, with the pressure receiving component and the pressure sensor being configured in a mating state.

[0019] Optionally, a fixing block is fixedly installed inside the second arc-shaped groove, and two sets of arc-shaped guide tubes are fixedly installed on both sides of the fixing block. The first arc-shaped tube is slidably installed on the outside of the arc-shaped guide tube, and an arc-shaped spring is fixedly installed at the connection between the first arc-shaped tube and the arc-shaped guide tube.

[0020] Optionally, the blowing assembly includes an air box fixedly installed on one side of another set of rack blocks, with an air outlet fixedly installed at the bottom of the air box, and the air outlet being flush with the mating slot.

[0021] In summary, this application includes at least one of the following beneficial technical effects:

[0022] This invention achieves the goal of keeping the reinforcing bar stable in the middle position for welding by having the first and second arc-shaped tubes contact the residual material deformation position on the surface of the reinforcing bar. The first and second arc-shaped tubes are rotated along the arc-shaped guide tubes by the reaction force of the deformation position until the first arc-shaped tube is completely in contact with the deformation position. This reduces errors and better clamps the reinforcing bar. Compared with traditional clamping methods, it avoids the situation where the bent part of the reinforcing bar is completely deformed or detached from the clamping mechanism due to excessive clamping, thus improving the safety of reinforcing bar welding.

[0023] The clamping position of the adaptive clamping component is further adjusted by the meshing of the gear and rack, which improves the accuracy of the distance movement of the adaptive clamping component. At the same time, the third motor is a forward and reverse motor, which can return the adaptive clamping component to its original position. After welding a single steel bar, it can quickly reset and clamp the next steel bar. The adaptiveness of the adaptive clamping component can better clamp steel bars according to different clamping requirements, thus improving the welding efficiency of steel bars.

[0024] Furthermore, the vibration transmitted from the reinforcing bar to the surface of the rack block below via the adaptive clamping assembly also generates corresponding vibration. The rack block then drives the pressure receiving assembly to move upward along the H-guide frame. The pressure receiving assembly squeezes the pressure sensor, and the pressure sensor transmits the information to the worker through the connected terminal, enabling the worker to urgently replace defective products, thereby improving the quality of reinforcing bar processing.

[0025] In summary, the present invention is easy to operate. Through the design of the adaptive clamping component, the reinforcing bar is completely clamped, avoiding displacement of the reinforcing bar and improving the stability of the reinforcing bar during welding. Attached Figure Description

[0044] Example

[0045] like Figure 1 - Figure 3As shown, the present invention proposes an automated welding equipment for precast steel bars, including a steel bar conveying frame 1, a steel bar conveying component 2 for conveying steel bars inside the steel bar conveying frame 1, a clamping and shifting component 3 for adjusting the clamping position on the top of the steel bar conveying frame 1, an adaptive clamping component 4 for clamping steel bars on one side of the clamping and shifting component 3, a cleaning component 5 for cleaning residual material on the surface of the adaptive clamping component 4 fixedly installed on one side of the steel bar conveying frame 1, and a laser welding component for welding steel bars on one side of the steel bar conveying frame 1.

[0046] In this embodiment, the rebar conveying assembly 2 includes a first motor 201 fixedly installed on one side of the rebar conveying frame 1. A drive gear 202 is fixedly installed at one end of the output shaft of the first motor 201, passing through the rebar conveying frame 1. A driven gear 203 is meshed with the outer side of the drive gear 202. Multiple conveying rods 204 are rotatably installed on the side of the rebar conveying frame 1 away from the first motor 201. The driven gear 203 is fixedly installed on the outer side of one of the conveying rods 204. A meshing sleeve 206 is fixedly installed on the outer wall of the three conveying rods 204. A conveyor belt 205 is rotatably installed on the three conveying rods 204 through the meshing sleeve 206. The first motor 201 drives the drive gear 202 to rotate, and the drive gear 202, through meshing with the driven gear 203, drives the driven gear 203 to rotate synchronously. 3. The connecting sleeve 206 drives the transmission belt 205 to rotate, and the transmission belt 205 synchronously drives the other multiple transmission rods 204 to rotate, so that the rebar can move forward to the clamping and shifting component 3, the adaptive clamping component 4 and the cleaning component 5 under the action of rotational force. The outer side of the transmission rod 204 is fixedly installed with a wire feeding wheel 207 with multiple wire feeding grooves on its surface. Multiple spring telescopic rods 209 are fixedly installed on one side of the wire feeding wheel 207, and a straightening ring 208 is fixedly installed on one side of the spring telescopic rod 209. When the rebar is transmitted to the wire feeding wheel 207, the straightening ring 208, under the action of the spring force inside the spring telescopic rod 209, fits and clamps the surface of the rebar, positioning the rebar in the center position. At the same time, it buffers the vibration of the rebar when welding, improving the stability of the rebar processing.

[0047] For details, please refer to Figures 4 to 6The clamping and shifting assembly 3 includes a guide rail frame 301 fixedly installed on the top of the rebar conveying frame 1. A built-in threaded block 304 is slidably installed inside the guide rail frame 301. A threaded rod 303 is threadedly installed inside the built-in threaded block 304. A second motor 302 is provided on one side of the threaded rod 303 and is fixedly installed on the top of the rebar conveying frame 1. An auxiliary rotating rod 305 is rotatably installed inside the built-in threaded block 304. Two sets of gears 306 are fixedly installed on the outer side of the auxiliary rotating rod 305. An H-guide bracket 308 is fixedly installed on the top of the reinforcing bar block 304. Two sets of rack blocks 307 are slidably installed inside the H-guide bracket 308. The two sets of rack blocks 307 are set to mesh with the gear 306. The lower set of rack blocks 307 is fixedly installed on one side of the arc-shaped fixing bracket 401. According to the actual clamping position requirements of the reinforcing bar, the threaded rod 303 is driven to rotate by the second motor 302. The threaded rod 303 drives the built-in threaded block 304 to move along the guide rail frame using the thread connecting the threaded rod 303 to the built-in threaded block 304. 301 slides, and the built-in threaded block 304 drives the adaptive clamping component 4 and the cleaning component 5 to move synchronously to a fixed position through two sets of rack blocks 307. After the rebar transmission component 2 transmits the rebar of the specified length each time, the third motor fixedly installed on the top of the built-in threaded block 304 drives the auxiliary rotating rod 305 to rotate through its output shaft. The auxiliary rotating rod 305 meshes with the rack block 307, which drives the rack block 307 to move along the H guide frame 308 toward the rebar position until the adaptive clamping component 4 clamps the rebar. The clamping position of the adaptive clamping component 4 is adjusted by the meshing of the gear 306 and the gear teeth of the rack block 307, which improves the accuracy of the distance movement of the adaptive clamping component 4. At the same time, the third motor is a forward and reverse motor. The third motor can return the adaptive clamping component 4 to its original position. After welding a single rebar, it can quickly reset and clamp the next rebar. The adaptiveness of the adaptive clamping component 4 can better clamp rebars with different clamping requirements, thus improving the welding efficiency of the rebar.

[0048] Furthermore, a sliding cavity plate 309 is fixedly installed on one side of the H-guide frame 308, and a pressure sensor 311 is fixedly installed inside the sliding cavity plate 309. An auxiliary spring 310 is fixedly installed between the pressure sensor 311 and the sliding cavity plate 309. A pressure receiving assembly 312 is slidably installed on one side of the H-guide frame 308, and the pressure receiving assembly 312 is set in a mating state with the pressure sensor 311. (Refer to...) Figure 5During the clamping process of the adaptive clamping component 4, the plate-shaped mechanism at the bottom of the pressure receiving component 312 and the rack block 307 remain in contact. The plate mechanism at the bottom of the pressure receiving component 312 is slidably installed on one side of the H guide frame 308. A spring for restoring the original position is fixedly installed at the connection between the pressure receiving component 312 and the H guide frame 308. When the rack block 307 drives the adaptive clamping component 4 to clamp the steel bar, if the steel bar vibrates during the welding process due to factors such as porosity and slag inclusions, the vibration is transmitted to the surface of the rack block 307 below through the adaptive clamping component 4, and the rack block 307 drives the pressure receiving component 312 to move upward along the H guide frame 308. The pressure receiving component 312 squeezes the pressure sensor 311, and the pressure sensor 311 transmits the information to the worker according to the connected terminal, so that the worker can urgently replace the defective product, thereby improving the quality of steel bar processing.

[0049] For further details, please refer to Figure 6 and Figure 7 The adaptive clamping assembly 4 includes an arc-shaped fixing frame 401. Multiple sets of first arc-shaped tubes 403 are rotatably mounted inside the arc-shaped fixing frame 401 via a first arc-shaped groove. Multiple sets of second arc-shaped tubes 404 are rotatably mounted on one side of the multiple sets of first arc-shaped tubes 403 via a second arc-shaped groove. Multiple fitting slots 402 are fixedly mounted on the side of the second arc-shaped tubes 404 away from the first arc-shaped tubes 403. A fixing block 406 is fixedly mounted inside the second arc-shaped groove. Two sets of arc-shaped guide tubes 407 are fixedly mounted on both sides of the fixing block 406. The first arc-shaped tubes 403 are slidably mounted on the outside of the arc-shaped guide tubes 407. An arc-shaped spring 405 is fixedly mounted at the connection between the first arc-shaped tubes 403 and the arc-shaped guide tubes 407. The arc-shaped guide tubes 407, the arc-shaped springs 405, and the fixing block 406 respectively limit the rotation angle of the second arc-shaped tubes 404 and the first arc-shaped tubes 403, and restore the second arc-shaped tubes 404 and the first arc-shaped tubes 403 to their original positions using elastic force when no external force is applied.

[0050] like Figure 8As shown, the second arc-shaped tube 404 and the first arc-shaped tube 403 have corresponding variable clamping directions at the deformation position of the reinforcing bar. A corresponding spring is fixedly installed between the rack block 307 and the arc-shaped fixing frame 401. Compared with traditional clamping components, which rely on plate-shaped or clamping plates adapted to the surface of the object to clamp it, in this application, when the adaptive clamping component 4 clamps the reinforcing bar under the push of the rack block 307, multiple sets of second arc-shaped tubes 404 preferentially contact the reinforcing bar. Since some parts of the second arc-shaped tubes 404 protrude... The steel pipe first contacts the reinforcing bar through the arc-shaped fixing frame 401. If the steel pipe surface has a large deformation, the first arc-shaped tube 403 can deflect along the first arc-shaped groove. As the reinforcing bar conveying component 2 pushes, the first arc-shaped tube 403 deflects along the first arc-shaped groove until it generates a contact resistance against the defect area of ​​the reinforcing bar. At this point, the deflection of the first arc-shaped tube 403 ends, meaning it completely contacts the deformed position, forming resistance to the movement of the reinforcing bar. At this time, the thrust given by the arc-shaped fixing frame 401 can be fully transferred from the second arc-shaped tube 404 to the steel bar. On the reinforcing bar, a first adaptive clamping mechanism is formed. The connection between the first arc-shaped tube 403 and the arc-shaped fixing frame 401 and the connection between the second arc-shaped tube 404 and the first arc-shaped tube 403 are consistent. Therefore, when there are burrs or small deformation surfaces in the reinforcing bar, since the burrs or small deformation surfaces are not clamped too tightly, the reinforcing bar transmission component 2 can continue to push. The second arc-shaped tube deflects along the first arc-shaped groove until the second arc-shaped tube 404 generates a contact resistance against the small deformation surface of the reinforcing bar. Then the deflection of the second arc-shaped tube 404 ends, forming a second adaptive clamping mechanism. Since the arc-shaped fixing frames 401 on both sides remain stationary and the movement distance between them is consistent, the reinforcing bar is stably clamped in the middle position. This achieves the goal of keeping the reinforcing bar stable in the middle position for welding, reducing errors, and better clamping the reinforcing bar. Compared with traditional clamping methods, it avoids the situation where the bent parts of the reinforcing bar are completely deformed or detached from the clamping mechanism due to over-clamping. At the same time, there are corresponding clamping schemes for different deformation areas of the reinforcing bar, thereby improving the safety of reinforcing bar welding.

[0051] As the first arc-shaped tube 403 rotates along the arc-shaped conduit 407 under the guidance of the arc-shaped conduit 407, since arc-shaped springs 405 are provided on both sides of the fixed block 406, the arc-shaped springs 405 can stably reset the first arc-shaped tube 403 no matter which side it deflects to.

[0052] In this embodiment, the cleaning component 5 includes an air box 501 fixedly installed on one side of another set of rack blocks 307. An air outlet 502 is fixedly installed at the bottom of the air box 501. The air outlet 502 is flush with the mating slot 402. Whenever the laser welding component finishes welding the steel bar, the adaptive clamping component 4 ends the clamping of the steel bar. Since the surface of the previous steel bar has a certain amount of residual material generated during the welding process, the air box 501 cleans the slot of the mating slot 402 below through the air outlet 502 to avoid affecting the clamping of the next steel bar and causing the steel bar to be clamped and deformed.

[0053] The above specific embodiments are merely optional embodiments of the present invention. Based on the technical solutions of the present invention and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
