This article introduced the problem of universal tools being unable to complete fastening is due to the small gap between the forced guide device and the frame installation position during the assembly process of the bo-gie in the development project of medium and low-speed maglev vehicles,and the multi-component connection structure of the device to be tightened.A bidirectional tightening tool for multi-part connected structures is pro-posed,which can solve the assembly problem of multi-component connection structures with slotted nuts in nar-row operating space,and can reduce the number of customized tools used in the tightening process,reduce the number of operators,and improve work efficiency at the same time.
