摘要:
转向架构架是跨坐式单轨车辆的核心部件。如何减小其焊接变形及控制构架尺寸，是工艺技术攻关的重点。侧梁作为构架的关键结构，焊后尺寸控制成为构架组焊的关键项点及难点。设计制作了一种组合式侧梁组装定位工装，用于侧梁部件的组装定位及焊接变形控制，实现了对侧梁组焊过程中尺寸的有效控制；创新采用了带刻度的调整螺杆，可以快速准确地量化反馈组装尺寸及变形量。结合对比焊后转向架尺寸，实现对侧梁组焊尺寸的持续优化及良好控制。

Bogie frame is the core component of straddle monorail vehicles, the key technological and difficult points in bogie welding process are to reduce the welding deformation and frame size. Side member is the core component of bogie frame, the key items and difficult points lie in the control of bogie frame size after welding. In this paper, a set of combination jigs are designed for the side member position and welding deformation, aiming to control the bogie frame size after welding. The innovative point of the design is to adopt the adjustment screw with scale which can harvest the feedback of assembly size and welding deformation accurately and quantitatively. By comparing the bogie frame sizes after welding, continuous optimization and good control of the side member size could be achieved.
