Problems solved by technology

[0005] In order to solve the existing side beam manufacturing method, it is necessary to use a large number of screw-type positioning clamps to accurately position each vertical rib, transverse rib and two cap tubes from the three coordinate axes, not only the screw-type positioning clamps are very large , the cost is high, it is not convenient for storage management, and the positioning adjustment process requires repeated calibration and clamping, resulting in high labor intensity for the operator and low positioning efficiency; and the

Abstract

The invention provides a passenger train framework side frame welding positioning tooling, and belongs to the field of bogie welding of railway vehicles. The tooling includes a base, two cap tube centering mechanisms, two cap tube compacting mechanisms, two inclined plane stud positioning mechanisms, two vertical plate compacting mechanisms, three plane stud positioning mechanisms, two transversebar positioning mechanisms, a plurality of lower cover plate compacting mechanisms, two vertical plate lateral jacking mechanisms, four reference positioning blocks, a lower cover plate positioning block pressing pincer and a lower cover plate positioning block. According to the invention, the work load of the welding procedure of a side frame lower cover plate assembly is simplified, the operation difficulty in vertical plane calibration and deformation after welding is directly reduced, the overall working efficiency is improved; and the calibration mapping required for positioning adjustment is reduced, so that the labor intensity is reduced, the precision in assembly positioning is improved, and the production efficiency is improved.

Description

technical field [0001] The invention belongs to the field of rail vehicle bogie welding, and in particular relates to a welding positioning tool for the frame side beam of a railway passenger car. Background technique [0002] The vertical plane is a vertical plane passing through the central axis of the bottom surface of the geometric body, which refers to the section that can divide the symmetrical geometric body into two parts of mirror symmetry along the vertical direction. [0003] like figure 1 As shown, the rail vehicle bogie side beam 1 is a box-shaped integral weldment structure similar to the wings of a bird. Its two wing-shaped side sill vertical plates 1-2 are parallel to each other, and are respectively welded and fixedly connected with the corresponding side sill lower cover plates 1-1, thereby forming a load-bearing main frame. Two approximately elliptical cap cylinders 1-4 are symmetrically fixed to the left and right ends of the load-bearing main frame, an...
