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...

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 lack of easy-to-measure positioning reference objects on the main load-bearing frame structure, resulting in installation When the clamp is positioned, it is necessary to measure the length of the load-bearing main frame in order to calculate and obtain the position of its midpoint, and then to determine the technical problem of the positioning centerline and mid-vertical plane of the load-bearing main frame structure on the machine tool. The present invention provides a Welding positioning tool for side beam of railway passenger car frame
