It can improve production efficiency, reduce production costs, and ensure the quality and reliability of welded joints.

[0003] During the welding process, a large amount of smoke and dust will be generated. For example, a smoke exhaust device for a flexible welding platform disclosed in Chinese Patent CN208929509U is simple and convenient to install, and at the same time has a high degree of installation freedom. Welding personnel can freely determine the installation position of this device according to the state of the welded workpiece, making the application range of this device wider and protecting the working environment of welding personnel. However, this smoke exhaust device cannot change the smoking angle according to the change of the welding position on the welding platform, and it is not convenient to use. Therefore, we propose a smoke exhaust device for a welding platform. Summary of the Utility Model

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.

[0031] Please refer to Figures 1-3 , the present utility model provides a smoke exhaust device for a welding platform, including a mounting base plate 1, a connection component installed at the bottom of the mounting base plate 1, a support platform 10 installed at the bottom of the mounting base plate 1, and a smoke suction component installed at the bottom of the support platform 10. A support component with one end movably connected to the support platform 10 is installed outside the smoke suction component, and a driving component for driving the support component to deflect at one end is also installed on the mounting base plate 1.

[0032] The mounting base plate 1 is fixed on the welding platform by using the connection component, and then the support component supports the smoke suction component to absorb and process the smoke generated during the welding process, reducing air pollution in the working environment and ensuring the physical health of the operators. At the same time, the driving component can drive the support component to deflect left and right, thereby changing the smoke suction angle of the smoke suction component, facilitating the change of the smoke suction angle according to the change of the welding position on the welding platform, and achieving a better smoke exhaust effect.

[0033] The connection component includes a connecting frame 2 installed at the bottom of the mounting base plate 1, a screw 3 threadedly connected to the connecting frame 2, a fastening gasket 4 installed on the screw 3, and a nut 5 threadedly connected to the outside of the screw 3. The welding platform is clamped in the connecting frame 2, then the screw 3 is tightened so that the fastening gasket 4 closely adheres to the surface of the welding platform, and then the screw 3 is fixed by using the nut 5, fixing the smoke suction component on the welding platform to absorb and process the smoke generated during the welding process.

[0034] The smoking component includes a smoke passage pipe 6 installed on the top of the support platform 10, a corrugated hose 7 and an exhaust pipe 9 communicated with the smoke passage pipe 6, a smoke collecting hood 8 communicated with the corrugated hose 7, and a suction fan 12 and a filter cotton 11 installed in the smoke passage pipe 6. When the suction fan 12 is started, the smoke generated by welding is inhaled into the smoke passage pipe 6 through the smoke collecting hood 8 and the corrugated hose 7, and after being filtered by the filter cotton 11, it is discharged through the exhaust pipe 9, so as to absorb and process the smoke generated during the welding process, reduce the air pollution of the working environment, and ensure the physical health of the operators.

[0035] One side of the smoke collecting hood 8 away from the corrugated hose 7 is designed with a flared opening. The smoke collecting hood 8 is designed in a flared shape, which can increase the contact area with the smoke, and can more comprehensively inhale the smoke generated during the welding process for treatment.

[0036] The support component includes a support ring 13 installed outside the smoke collecting hood 8, a connecting sleeve rod 14 installed on the support ring 13, a connecting support rod 15 slidably connected in the connecting sleeve rod 14 and extending to the outside at one end, and a bolt 16 threadedly connecting the connecting support rod 15 and the connecting sleeve rod 14. A plurality of screw holes adapted to the bolt 16 are formed on the connecting sleeve rod 14.

[0037] The connecting support rod 15 slides in the connecting sleeve rod 14, and the position of the connecting support rod 15 on the connecting sleeve rod 14 is fixed by relying on the connection of the bolt 16 and the screw hole, so as to change the horizontal height of the support ring 13, and further make the smoking angle of the smoke collecting hood 8 can be slightly adjusted upward or downward, so as to better adsorb the smoke generated during the welding process.

[0038] An arc-shaped groove 22 is formed on the mounting base plate 1. The bottom of the connecting support rod 15 extends into the arc-shaped groove 22 and is movably connected thereto. The arc-shaped groove 22 provides a support point for the movement of the connecting support rod 15.

[0039] The support platform 10 is cylindrical, and the center of the support platform 10 coincides with the center of the arc-shaped groove 22, so that the connecting support rod 15 drives the smoke collecting hood 8 inside the support ring 13 to deflect left and right with the support platform 10 as the center to change the smoking angle.

[0040] The driving component includes a servo motor 17 installed on the top of the mounting base plate 1, a gear one 18 connected to the output shaft of the servo motor 17, a gear two 19 rotatably connected to the outside of the support platform 10 and meshing with the gear one 18, a connecting ring 20 installed at the bottom of the gear two 19 and sleeved on the outside of the support platform 10, and a cross bar 21 connecting the connecting ring 20 and the connecting support rod 15.

[0041] The servo motor 17 starts to drive the first gear 18 to rotate clockwise or counterclockwise. The first gear 18 meshes with the second gear 19, thereby causing the second gear 19 to rotate clockwise or counterclockwise outside the support platform 10, so that the connecting ring 20 keeps rotating synchronously with the second gear 19, and then drives the smoke collecting hood 8 on the connecting support rod 15 to deflect left and right, facilitating the change of the smoking angle according to the change of the welding position on the welding platform, and the smoke exhaust effect is better.

[0042] The inner wall of the connecting ring 20 is smooth and does not contact the outside of the support platform 10, which is beneficial to reducing the resistance received by the connecting ring 20 during rotation, making the movement of the cross bar 21 smoother and facilitating the angle change of the smoke collecting hood 8.
