The invention discloses a stator screw hole position testing fixture. The testing fixture comprises a base, positioning seats are installed in the middle of the base, the positioning seats are provided with fixation pin holes, fixation pins interpenetrate the fixation pin holes, a detection plate is fixed at one side of the base, a positioning pin hole is arranged in the middle of the detection plate, a positioning pin interpenetrates the positioning pin hole, first detection pin holes are arranged at positions near to the left side and the right side of the detection plate, detection pins interpenetrate the first detection pin holes, a horizontal guide rail plate is fixedly installed on the base, a vertical guide rail plate is arranged at a near distance at the side which is close to the detection plate, of the horizontal guide rail plate. According to the stator screw hole position testing fixture, a stator needing to be detected is firstly fixed, the detection pins are then inserted, and the accuracy of hole positions can be quite easily determined through observation of the alignment degree of the hole positions. Besides, through arrangement of dial gauges in a horizontal direction and a vertical direction, the deviation degree of the hole positions can be further accurately detected.
