The invention discloses an aluminum alloy riveting subway vehicle side wall total installing and welding flexible tool. The aluminum alloy riveting subway vehicle side wall total installing and welding flexible tool comprises at least two annular hand wheels. Two sets of side wall tool mechanisms are arranged between the annular hand wheels. The two tool mechanisms are symmetrically arranged in a front-and-back mode. Each side wall tool mechanism comprises an upper fixing plate, a lower fixing plate, a plurality of upper side beam clamps, lower side beam clamps corresponding to the upper side beams, and a beam locking device arranged between the upper side beam clamps and the lower side beam clamps. The upper fixing plates are parallel to the lower fixing plates. The upper side beam clamps are arranged on the upper fixing plates, the lower side beam clamps are arranged on the lower fixing plates, and the beam locking devices are connected between the upper fixing plates and the lower fixing plates through tool bases. The aluminum alloy riveting subway vehicle side wall total installing and welding flexible tool is suitable for side wall installing and welding of multiple items, the improvement cost is low, the period of the new item tool preparation is shortened, the tool occupied space is saved, the accuracy and consistency of the tool are guaranteed, the productivity is improved, and the flexibility of the tool is fully guaranteed.

The invention discloses a frication stir welding flexibility tool for a subway vehicle side wall. The frication stir welding flexibility tool comprises a pair of I-shaped beam bases, four square steel bases symmetrically arranged on the two sides of the I-shaped beam bases respectively, multiple locating and clamping mechanisms installed on the square steel bases in a sliding manner, multiple beams installed on the I-shaped beam bases in a sliding manner and a turnover mechanism. Every two adjacent beams are connected with a pair of rotary welding joint supporting strips and a pair of fixed welding joint supporting strips in a sliding manner. The tool is suitable for frication stir welding of the subway vehicle side wall; common features of existing and following projects are fully considered, the universality of the tool is improved; high cost for a newly-made tool is saved; the preparation cycle of tools for new projects is greatly shortened; the space and the position occupied by the tool are saved; the project production tool switching time spent in the multi-project combined production process is shortened; the accuracy and uniformity of the tool are guaranteed; and the capacity is improved. The tool is good in reliability, simple in structure, high in efficiency and suitable for practical application.
