The invention, which relates to the technical field of mechanical part processing, discloses a spline shaft fork ear hole position accuracy testing fixture comprising a substrate, and the substrate is provided with a rotary table which can rotate around the axis of the rotary table. The first sharp shaft is fixed on the rotary table; the first sharp shaft protrudes upwards and is configured to be a lower center hole upwards jacking the spline shaft fork; a through hole is formed in a shaft body of the first sharp shaft, and the diameter of the through hole is the same as that of a lug hole of the spline shaft fork; the outer diameter of the mandrel is the same as the diameter of the through hole; the mandrel is configured to penetrate through the lug hole of the spline shaft yoke and the through hole at the same time; the second sharp shaft is positioned right above the first sharp shaft; the second sharp shaft protrudes downwards and is configured to abut against an upper center hole of the spline shaft fork
