Plate rolling motor assembly fixture

The utility model discloses a plate rolling motor assembly fixture, comprising a lower formwork, an upper formwork, slide blocks, seam allowance cutters, a press casing upper die, slide block rods and a buffer mechanism. The press casing upper die presses a casing and pushes the casing into a stator, and drives the seam allowance cutters to rivet the casing under the cooperation of the slide blocks and the slide block rods; a present process of installing a spring through stator drilling is changed to be a process of seam allowance positioning by riveting, and to be in combination with a process of entering a stator into the casing, thereby once completing motor stator entering the casing and seam allowance positioning by riveting, reducing equipment cost and artificial cost, and improving entire line production efficiency and personnel labor intensity.
