A transposition device for steel component welding

Abstract

The invention provides a transposition device for steel component welding, which belongs to the technical field of steel component processing equipment. The transposition device includes two gantry frames, two positioning and rotating mechanisms and a servo motor. There is a synchronous rotating shaft connected in rotation between the two gantry frames. One end of the synchronizing rotating shaft is connected with the output shaft of the servo motor. Two positioning and rotating mechanisms They are all arranged between two gantry frames. The positioning and rotating mechanism includes a cylindrical rotating body. The rotating body is provided with a strip-shaped slot that runs through the surrounding surface of the rotating body. The rotating body is fixed on the synchronous shaft, and the bar-shaped slot is provided with a clamping structure capable of clamping the steel member inserted in the bar-shaped slot. The bar-shaped slots of the two rotating bodies On the same straight line, the bar-shaped slot is parallel to the synchronous shaft, and there is a working area between the two rotating bodies to facilitate welding of the ends of the steel components. The invention has the advantages of low construction difficulty and the like.

Problems solved by technology

[0002] Steel components often need to be welded due to their length. Due to their large mass, long length (especially during the second-stage welding), and high welding requirements, the welding quality is often poor because the steel components cannot be turned over smoothly to change the welding position. Difference

[0003] After searching, the Chinese patent with the publication number [CN110919281A] discloses a steel member turning and displacing device, its purpose is similar to the present application. Clamping, and then switching the welding position through the synchronous rotation of the two rotating gear rings, there are the following problems: 1. It is difficult to align the two steel components to be welded, because manpower or lifting equipment is required to lift the steel components to the rotating gear ring position, and then insert the steel member into the rotating gear ring. If the steel member is clamped at this time, the position of the two steel members cannot be fine-tuned and aligned. It is extremely difficult to control the alignment by lifting equipment , and the long steel members are bent under force, so the construction of this device is more difficult, because the steel members need to be inserted for each welding, and the steel members need to be taken out after welding, the construction period is long and the efficiency is low; 2. In the device , the clamping of the steel member is achieved through multiple splints, which come from different directions. During the clamping process, each splint is not synchronized, that is to say, even if the steel member is suspended in a position that can be aligned by the lifting device, through Dislocation and movement will also occur after the action of the splint, resulting in low alignment accuracy; 3. The steel component is transposed through the rotation of the rotating gear ring. During the rotation process, the steel component is heavy and the tail is in a shaking state. The rotating tooth ring with tooth meshing has a large load-bearing, and its meshing gap will cause the welding end to be subjected to a large external force, which will produce continuous stress on the welding end of the steel member, and the direction is constantly switched with the rotation, especially when there are not many welding positions and the welding strength is high. When it is weak, it is easy to cause the welding position to loosen and disconnect during the rotation process, which is not conducive to construction
