Auxiliary device for dismounting stator and rotor of single-screw pump

The utility model relates to the technical field of screw pumps, in particular to an auxiliary device for dismounting a stator and a rotor of a single-screw pump, which comprises a base, a lower mounting plate and an upper mounting plate, the lower mounting plate and the upper mounting plate are vertically arranged above the base from bottom to top, the lower mounting plate is connected with the base, and the upper mounting plate and the lower mounting plate are detachably connected. An upper fixing groove and a lower fixing groove which are of semicircular structures are oppositely formed in the bottom of the upper mounting plate and the top of the lower mounting plate, the upper fixing groove and the lower fixing groove are in butt joint to form a stator fixing hole, and a pull rod limiting groove is formed in the lower mounting plate and/or the upper mounting plate. The upper mounting plate and the lower mounting plate are in butt joint with the outer side of the stator of the single-screw pump in an openi
