1 组装夹具的性能给安装组装定位装置提供了有利条件 棚车底架组装夹具能保证中梁落放后的横向位移和纵向位移。在 1位牵引梁头部用组装端梁的风动装置推动中梁 ,使 2位牵引梁上的后从板座垂直面和中梁纵向定位器垂直面靠严。中梁垂向用下压装置压靠于定位座上 ,使中梁在纵
1 The performance of the assembly fixture provides favorable conditions for the assembly and assembly of the positioning device. The box assembly fixture ensures lateral displacement and longitudinal displacement of the center beam. In the head of a traction beam, the middle beam is pushed by the pneumatic device of the assembled end beam so that the vertical plane of the rear of the two traction beams and the longitudinal positioner of the middle beam are tight. The vertical beam with a pressing device pressed against the positioning seat, so that the beam in the vertical
