Abstract

The invention discloses an assembly tooling and method of frameworks and guide frame bodies. The tooling comprises a locating seat used for fixing the four guide frame bodies and framework measurement pins, wherein a clamping device used for clamping the guide frame bodies is arranged on the locating seat; the frameworks are arranged on the guide frame bodies; first adjusting workpieces are arranged on the two sides of the frameworks; the first adjusting workpieces can be adjusted relative to the guide frame bodies to be in contact with the frameworks to adjust the positions, relative to the guide frame bodies, of the frameworks; and the framework measurement pins are arranged in central holes of the frameworks. According to the assembly tooling, the structure is simple, the guide frame bodies are convenient to adjust, after being determined on the locating seat, the guide frame bodies and the frameworks are welded in pairs, the pairing precision is high, follow-up processing is not required, and the operation is convenient; and the assembly tooling cooperates with a measurement ruler to quickly determine the positions of the guide frame bodies and the frameworks, so that the production efficiency is effectively improved, and the production cost is reduced.

Description

technical field [0001] The invention relates to the field of railway welding bogie manufacturing, in particular to an assembly tool and method for a frame and a pedestal body. Background technique [0002] like Figure 5 and Image 6 As shown, in the prior art for the railway bogie, for the frame 6 and the pedestal body 7, the positioning of the tooling frame 6 adopts the shape positioning. If the shape size changes, the positioning will not be accurate, and the frame center and the pedestal body that are paired with each other cannot be guaranteed. The center coincides, which in turn affects product quality and production efficiency. According to the product drawings, the center hole should be used for positioning, but because of the formal installation, it is not easy to design a positioning mechanism for the center hole on the carcass. [0003] The four pedestal bodies and frame of the welded bogie are formed by pair welding. Since the center of the four pedestal bodie...
