The invention discloses a fixture switching and storage system which is used for the field of fixture switching. The fixture switching and storage system comprises a working rotary table, the periphery of a rotation center is provided with a plurality of working platforms, when the working rotary table rotates, the working platforms can be switched between working positions and switching positions, the periphery of the working rotary table is provided with at least one set of fixture storage unit, each fixture storage unit comprises a three-dimensional storage warehouse position and a lifter,wherein each three-dimensional storage warehouse position is provided with a plurality of layers of warehouse positions, the multiple layers of warehouse positions are distributed in the height direction, each lifter is provided with a lifting tray and a lifting driving mechanism, and each lifting driving mechanism can drive the corresponding lifting tray to be butted to the warehouse positions orto be butted to the working platforms switched to the switching positions to perform fixture handover. According to the fixture switching and storage system, the three-dimensional type storage warehouse position is adopted, compared with a ground storage mode, the occupation area is significantly reduced, meanwhile, the fixture switching and storage system adopts the working rotary table to perform the fixture switching, the fixture switching process is simplified, and the fixture switching time is greatly reduced.
