[0026] The two anti-slip clamping devices 35 in the profile steel pose adjusting table 1 are completely symmetrical to each other, a first linkage shaft 45 is coaxially fixedly connected between the two first sprockets 36, the left and right ends of the first linkage shaft 45 pass through the two first sprockets 36 and are rotatably connected to the top of the left and right sides of the inner wall of the profile steel pose adjusting cabinet 24, the middle of the first linkage shaft 45 is in transmission connection with the rotating shaft of the rear end of the third worm 30 through a bevel gear set, a second linkage shaft 46 is coaxially fixedly connected between the two second sprockets 37, the left and right ends of the second linkage shaft 46 pass through the two lower bearing plates 33 and are rotatably connected thereto; The outer side of the second sprocket 37 is coaxially fixedly connected to the second transmission wheel 38.

[0028] Working principle: such as Figures 1-3 As shown, the H-beam is placed into the square channel tube 28 of the steel cylinder ring 26 through the equipment until both ends pass through the square channel tube 28. During the process, each auxiliary support roller 29 will assist the movement of the H-beam and play a supporting role. After the DC motor 8 of the welding table 4 is started, the first worm 9 drives the first worm wheel 11 to rotate, and the first worm wheel 11 drives the internal threaded sleeve 10 to rotate. Under the action of the lead screw 5, the welding table 4 can move back and forth on the guide rail 3, so that the robotic arm welding gun 7 can weld different positions of the steel. At the same time, the internal threaded sleeve 10 can also drive the first transmission wheel 14 to rotate through the bevel gear set, the first transmission rod 12 and the second transmission rod 13. The first transmission wheel 14 then causes the hammer 18 to swing up and down stably along an arc path through the spring telescopic rod 15, realizing the function of striking the welding slag during the movement. Since the hammer rod 16 and the spring telescopic rod 15 are detachable, the hammer rod 16 can be installed after all welding is completed for moving and hammering, or the hammer rod 16 can be installed first and then welding and slag hammering can be carried out simultaneously. like Figures 4-8 As shown, when the steel needs to be flipped, crank 20 is turned to drive the second worm 21 and the second worm wheel 22 to rotate, which in turn drives the linkage rod 23 to rotate. The linkage rod 23 drives the third worm 30 to rotate through the bevel gear set, which in turn drives the frame steel cylinder ring 26 to rotate, thus realizing the four-sided flipping of the steel. At the same time, during the flipping process, the third worm 30 drives the first sprocket 36 to rotate through the first linkage shaft 45. Under the action of the chain and the second linkage shaft 46, the second sprocket 37 is further driven to rotate, so that the second transmission wheel 38 rotates synchronously. During the process, the first connecting rod 39, with the assistance of the limiting square tube 34, causes the lifting tube 40 to move back and forth. With the cooperation of the hinge seat 41 and the second connecting rod 43, the second sprocket 37 rotates one revolution, and then the clamping arm 42 completes the action of releasing and re-clamping. The size of each transmission member is selected and the appropriate transmission ratio is determined, so that when the steel cylinder ring 26 rotates one fourth, the second sprocket 37 rotates one circle, that is, the steel material turns over one side to be upward, the clamping arm 42 completes the action of loosening and clamping again, and effectively prevents slip during the welding process.

[0029] Finally, it should be noted that: the above only for the preferred embodiments of the present application, and not for limiting the present application, although the foregoing embodiments of the present application are described in detail, for those skilled in the art, it still can be modified, or the equivalent replacement of part of the technical features described in the foregoing embodiments.
