Description

Internal bracing type welding auxiliary device capable of adapting to size of cylinder Technical Field The utility model relates to the technical field of pipeline welding, in particular to an internal bracing type welding auxiliary device capable of adapting to the size of a cylinder. Background In pipeline welding operation, it is important to ensure stable support and accurate positioning of the pipeline. Traditional welding auxiliary support device often structure fixed, is difficult to the barrel of different diameters of nimble adaptation. When facing diversified pipeline size demands, operators have to frequently replace supporting equipment or carry out complex manual adjustment, which not only consumes a great deal of time and labor cost, but also is easy to cause uneven welding quality due to unstable supporting, and cannot meet the requirements of the modern welding process with high efficiency and high quality. Therefore, the utility model provides an internal stay type welding auxiliary device capable of adapting to the size of a cylinder body so as to solve the problems. Disclosure of utility model Aiming at the defects of the prior art, the utility model provides an internal bracing type welding auxiliary device capable of adapting to the size of a cylinder body, and solves the problems. The inner support type welding auxiliary device capable of adapting to the size of the cylinder comprises a frame, wherein a support assembly is arranged on the side face of the frame and comprises a sliding rail, the sliding rail is fixedly arranged on the side face of the frame, a sliding block is connected to the outer side of the sliding rail in a sliding mode, an inner support plate is fixedly arranged on the outer side of the sliding block, an inner support base plate is fixedly arranged on the outer side of the inner support plate, the outer side edge of the inner support base plate is arc-shaped, and the inner support plate and the inner support base plate are respectively arranged in the upper, lower, left and right directions of the side face of the frame. Preferably, a first air cylinder is fixedly arranged on the left side of the frame, the output end of the first air cylinder movably penetrates through the inside of the frame, an inner supporting core is fixedly arranged at the output end of the first air cylinder, and a connecting rod is hinged between the inner supporting core and a corresponding inner supporting plate.
