Description

TECHNICAL FIELD

[0001] The utility model relates to H type steel welding technical field, concretely to a H type steel welding turnover mechanism. BACKGROUND

[0002] H type steel is made by cutting, assembling and welding process. The manufacturing process is as follows: first, according to the design requirements, the steel plate is cut into a specific size. Then, the cut steel plate is assembled to form an H shape. Finally, the assembled steel plate is welded together by welding process to form a firm H type steel. H type steel is an economic section high-efficiency profile with more optimized cross-sectional area distribution and more reasonable strength-to-weight ratio. It is named after its cross section which is the same as the English letter "H". When welding, it needs to be turned over and welded to each surface.

[0003] The prior art such as publication number CN220296270U provides a novel H type steel welding device, which comprises a base, a second motor installed in the base, a second screw rod fixedly connected to the output end of the second motor, two third sliding blocks and two fourth sliding blocks penetrating through the middle of the second screw rod and being threadedly connected thereto; two symmetrical rotating rods are rotatably connected to the lifting seat, the fourth sliding block is rotatably connected to the end of the rotating rod away from the lifting seat, a turnover mechanism is arranged on the lifting seat, the lifting seat turns over the web of the H type steel by 180° and drives the web of the H type steel to move up and down; the clamping devices are arranged on both sides of the lifting seat, the clamping devices fix the flange plate of the H type steel through the second clamping blocks; the clamping devices on both sides are fixedly connected with the third sliding blocks through connecting rods.

Toothed rings 212 are fixedly connected to the sides of the two clamping discs 21 away from the clamping surfaces. A first servo motor 24 is fixedly connected to the left side of the support plate 11. A servo motor 24 has a rotating rod 241 fixedly connected to its output end. The rotating rod 241 is connected to the gear ring 212 via a transmission assembly 242. The transmission assembly 242 consists of a support 2421, a first gear 2422, and a second gear 2423. The support 2421 is fixedly connected to the bracket 23 at a position below the support ring 211. The first gear 2422 is rotatably connected to the inner wall of the support 2421 and meshes with the gear ring 212 at the corresponding position. The second gear 2423 meshes with the bottom of the first gear 2422 and is radially slidably connected to the outer wall of the rotating rod 241.

Then, the two sets of clamping plates 21 clamp the two ends of the spliced ​​H-beam to fix it, which facilitates subsequent flipping and welding. In specific operation, the first servo motor 24 drives the two second gears 2423 on the outer wall of the rotating rod 241 to rotate synchronously, thereby driving the first gear 2422 with the second gear 2423 to rotate. Then, the gear ring 212 drives the support rings 211 on the clamping plates 21 at both ends of the H-beam to rotate on the bracket 23, so as to facilitate the overall H-beam.

The first electric telescopic rod 251 extends into the interior of the clamping plate 21 and is fixedly connected to the piston disc 25.

[0037] In this embodiment, by setting sliding abutment blocks 261 inside the limiting frame 26 on the surface of the clamping plate 21, when it is necessary to clamp and fix the H-beam, the first electric telescopic rod 251 drives the piston plate 25 to squeeze the air in the inner wall of the clamping plate 21 into the inner wall of the limiting frame 26, so that the abutment blocks 261 on the inner wall of the limiting frame 26 extend and abut against the H-beam for clamping and fixing. Since the limiting frame 26 is distributed on the surface of the clamping plate 21 according to the shape of the H-beam, the extended abutment blocks 261 will clamp the two sides of the web of the H-beam, and the two sides of the flanges of the H-beam will be pushed against by the extended abutment blocks 261, so that they abut against the splice with the web of the H-beam, thereby ensuring the stability of the overall structure of the H-beam and improving the welding quality.
