Description

Technical Field

[0001] This utility model relates to the field of scaffolding welding clamping technology, and in particular to a scaffolding welding clamping mechanism. Background Technology

[0002] Currently, during the manufacturing process of scaffolding uprights, the buckle plate is fitted onto the upright, clamped by a clamping mechanism, and then welded and fixed by a welding head.

[0003] Among them, a search revealed Chinese patent CN222536648U, which discloses a welding device for scaffolding uprights. In the application of the above patent's technical solution, since the welding head is moving while the clamping block is stationary, the wires connected to the welding head are easily tangled when the welding head rotates, creating a safety hazard. Therefore, in order to better realize the scaffolding welding function, promote the technological progress of the industry, and improve the core technology competitiveness, this application proposes a new implementation scheme that is different from the clamping mechanism in the prior art. Utility Model Content

[0004] The purpose of this utility model is to solve the safety hazards that exist when welding scaffold uprights and clamping plates with existing welding equipment, and to propose a scaffold welding clamping mechanism.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A scaffolding welding clamping mechanism includes a side plate and two laser welding heads for welding scaffolding. Multiple clamping assemblies are provided on one side of the side plate. Each clamping assembly includes a connecting frame, which is bolted to one side of the side plate. A first motor is fixedly connected to the top of the connecting frame. A bidirectional threaded rod is keyed to the output end of the first motor. The bottom end of the bidirectional threaded rod is rotatably mounted on the bottom inner wall of the connecting frame via an interlocking bearing. Slide plates are threaded to both ends of the bidirectional threaded rod. A clamping block is fixedly connected to one side of the slide plate. A V-groove is provided on one side of the clamping block. Multiple movable wheels are rotatably connected to the inner wall of the V-groove. Two guide rods are fixedly connected between the bottom inner wall and the top inner wall of the connecting frame. The slide plate is slidably connected to the guide rods.

[0007] Furthermore, a top plate is fixedly connected to the top of the side plate, and two sets of adjustment components are provided at the bottom of the top plate.

[0008] Furthermore, the adjustment assembly includes a first electric push rod, which is fixed to the bottom of the top plate by bolts. A second electric push rod is fixedly connected to one end of the first electric push rod, and a fixing block is fixedly connected to the bottom end of the second electric push rod. The laser welding head is fixed to the fixing block by bolts.

[0009] Furthermore, a support platform is fixedly connected to the bottom of one side of the side plate, and a collection box is placed on the top of the support platform.

[0010] Furthermore, a third electric push rod and a piston rod are fixedly connected to the top of the support platform. The top ends of the third electric push rod and the piston rod are jointly fixedly connected to a support base. A second motor is fixedly connected to the top of the support base. A transmission wheel is keyed to the output end of the second motor.

[0011] Furthermore, the collection box has multiple air outlets on one side, with an exhaust fan fixedly connected inside each air outlet and a dustproof net fixedly connected inside each air outlet, the dustproof net being located outside the exhaust fan.

[0012] Furthermore, a filter screen is fixedly connected to the top between the inner walls of the multiple sides of the collection box.

[0013] The beneficial effects of this utility model are as follows:

[0014] 1. Driven by the first motor, the bidirectional threaded rod rotates, causing the two slides to converge towards the center along the guide rod, thereby clamping the steel pipe and buckle. Then, the steel pipe is rotated by the rotation of the transmission wheel under the scaffold, and the connection between the steel pipe and buckle is rotated and welded by the laser welding head, thus avoiding the easy entanglement of the wires connected to the welding head when it rotates.

[0015] 2. The laser welding head is moved by the first electric push rod, thus moving it above the connection between the steel pipe and the buckle plate. Then, the laser welding head is moved downward by the second electric push rod, so that the laser welding head contacts the connection between the steel pipe and the buckle plate, thereby improving the welding accuracy.

Under the drive of the first electric push rod 501, the laser welding head 2 moves, thereby moving the laser welding head 2 above the connection between the steel pipe and the buckle. Then, under the drive of the second electric push rod 502, the laser welding head 2 moves downward, thereby making the laser welding head 2 contact the connection between the steel pipe and the buckle. A fixing block 503 is fixed to the bottom end of the second electric push rod 502 by bolts, and the laser welding head 2 is fixed to the fixing block 503 by bolts.

[0030] The control panel is electrically connected to the first motor 307, the first electric push rod 501, the second electric push rod 502, the third electric push rod 8, and the second motor 11.

[0031] The working principle of this embodiment is as follows: In use, firstly, the steel pipe is inserted into the clamping components 3 on both sides, and then the buckle is placed in the clamping component 3 in the middle, so that the steel pipe and the buckle are connected. Then, the first motor 307 is started through the control panel. Under the drive of the first motor 307, the bidirectional threaded rod 302 rotates, so that the two slide plates 304 converge towards the middle along the guide rod 303, thereby clamping the steel pipe and the buckle. Next, the first electric push rod 501 and the second electric push rod 502 are started through the control panel. Under the drive of the first electric push rod 501, the laser welding head 2 moves, thereby moving the laser welding head 2 above the connection between the steel pipe and the buckle. Then, under the drive of the second electric push rod 502, the laser welding head 2 moves downward, thereby making the laser welding head 2 contact the connection between the steel pipe and the buckle.

[0032] Then, the third electric push rod 8 is started through the control panel. Under the drive of the third electric push rod 8, the support seat 9 moves upward, thereby driving the transmission wheel 10 to move upward and contact the steel pipe. Next, the second motor 11 is started through the control panel. Under the drive of the second motor 11, the transmission wheel 10 rotates, thereby driving the steel pipe. Then, the laser welding head 2 performs rotational welding on the connection between the steel pipe and the buckle.

[0033] Next, the exhaust fan 13 is turned on. Under the suction of the exhaust fan 13, the welding slag falls onto the filter screen 14 of the collection box 7. Finally, the gas is discharged from the air outlet 12.
