Flexible alignment device

The invention discloses a flexible alignment device. Two alignment stop blocks (7), two limiting blocks (6), and a double-sliding-block guide rail (1) are fixed with an alignment transition plate (8)through screws in a left-right symmetry mode; one ends of two buffer rods (2) are directly fixed on a fixing plate (3) through threads, two compressed springs (9) are arranged on one fixing plate (3)in a sleeved mode, the limiting blocks (6) and the fixing plate (3) are connected through two tension springs (10), two air cylinders (5) are connected with an adapter plate (12) and the alignment transition plate (8) through screws; deflector rods (4) are connected with the air cylinders (5) through screws, the deflector rods are inserted into grooves in the limiting blocks (6), and gaps are formed between the grooves and the deflector rods. The device can adapt to the to-be-aligned spaces with different sizes in a certain range, does not need to be adjusted, has good alignment effect, and isreliable in operation, eco
