Be equipped with many frock assemblies 5 between two chains 4 altogether, it has the hole site that is used for placing weldment 6 to open on the frock assembly 5, both sides top is provided with a plurality of elasticity inflatable members 7 relatively around the frame 1, and when frock assembly 5 contacted rather than a pair of elasticity inflatable members 7, the gas outlet of elasticity inflatable members 7 switched on with each hole site on the frock assembly 5. A protective cover 10 for covering the elastic inflatable member is further provided on the frame 1.

The transmission platform is only one part of the welding system and is only used for driving the weldment station to walk. In the whole welding system, a flux spraying nozzle, a preheating device and a welding gun are arranged above a transmission platform, a cooling device can be additionally arranged, the corresponding positions of the devices can be called a flux spraying station, a preheating station, a welding station and a cooling station, and a preassembling station is arranged in front of the flux spraying station. Each station can correspond to one or more tool assemblies. During operation, a preassembler inserts a weldment into a tooling assembly body on preassembling operation, manual preassembly or manipulator preassembly can be performed, the weldment is tubular, and the welding position is located at the top of the weldment. Under the transmission of chain, the frock assembly body walking of preassembleing the station position is to spouting the scaling powder station, spouts the scaling powder shower nozzle in this position and spouts the scaling powder towards the welding top. Then the chain drives to walk to the preheating station, and the preheating device preheats the welding. Then continue to walk to the welding station, aim at the frock assembly body at this station position elasticity inflation piece, fill protective gas, generally nitrogen gas to the frock assembly body, protective gas from the menstruation to the hole site, then spout from the weldment top, form the protective atmosphere, welder aims at the weldment top and accomplishes the welding. Then, the welding is continuously driven to walk to a cooling station, and the steel wire can be naturally cooled or cooled by a cooling device. Finally, the chain continues to drive, the weldment turns over to the lower side, a material receiving disc is placed at the position, the weldment naturally breaks away from the hole position and slides into the material receiving disc, and then the tooling assembly continues to travel until the tooling assembly continues to travel to the preassembly station to preassemble the weldment. Because the weldment walks to when spouting the scaling powder station from the preassembly station, follow-up frock assembly body that has walks to the preassembly station simultaneously, the preassembly personnel can accomplish welding preassembly in succession like this, and the weldment can be realized welding in succession at last by this transmission platform.

Obviously, the structure occupies small area, can realize continuous preassembly welding, can automatically discharge weldments, has high working efficiency, and can realize the ejection of protective gas from the weldments through ingenious structural design to form protective atmosphere. Therefore, the transmission table is simple in structure, low in cost and high in working efficiency.
