Background The fire extinguishing bomb is used as a high-efficiency and convenient fire extinguishing device, is widely applied in the field of modern fire control, and in order to improve the flight stability and action accuracy of the fire extinguishing bomb, additional parts are usually welded on the bomb body, and mainly comprise tail rods and a plurality of guide wings, usually four guide wings, which are uniformly distributed in the circumferential direction. The quality of the welding of these appendages is directly related to the ballistic performance and overall reliability of the extinguishing bomb. At present, the welding of the fire extinguishing bomb accessory is mostly finished by adopting manual operation or semi-automatic equipment. The manual welding mode has the problems of low efficiency, high labor intensity, obvious influence of skill level of operators on welding quality, difficulty in ensuring consistency and the like, and the existing semi-automatic welding equipment can partially replace manual work, but has the defects in workpiece circulation, positioning, clamping and multi-station continuous operation, and generally needs manual frequent intervention, such as manual transfer of fire extinguishing bombs among different stations, clamping of tail rods and guide wings respectively, and the like, so that the production efficiency is not only influenced, but also accurate angle positioning among the guide wings is difficult to realize, if 90-degree included angles are required between adjacent guide wings, and product consistency is poor easily caused by personal errors. In addition, for fire extinguishing bombs of different batches or models, certain differences may exist in size and shape, and the clamping mechanism of the existing equipment often lacks enough self-adaptability and universality, so that the replacement and adjustment are complicated, and the production flexibility is affected. Therefore, a special device which can realize full-automatic and continuous welding of the additional parts of the fire extinguishing bomb and automatically drive the fire extinguishing bomb to rotate ninety degrees in the welding process so as to ensure that a plurality of guide wings can be welded at specified positions of a tail rod or a bomb body according to set angle intervals is urgently needed in the industry.
