Five-axis space precision measurement fixture

A five-axis space precision measurement fixture, comprising:

• a body, at least having a first surface, a third surface, a fourth surface and an inclined surface, the first surface and the third surface being neighbored and perpendicular to each other, the fourth surface being neighbored with the first surface and the third surface and perpendicular to each of the first surface and the third surface, the inclined surface neighboring the first surface and forming an angle of 45° to the third surface;
• a plurality of first-ball screw holes, arranged on the first surface in an equal-spacing manner to form a plurality of rows and a plurality of columns, each row of the plurality of rows being parallel to the third surface, each column of the plurality of columns being perpendicular to the third surface, each of the plurality of first-ball screw holes having an axial direction parallel to a first direction, the first direction being perpendicular to the first surface;
• and
• a plurality of second-ball screw holes, arranged on the inclined surface along a tilt direction in an equal-spacing manner, each of the plurality of second-ball screw holes having an axial direction parallel to a second direction, the second direction being perpendicular to the third surface, the second direction and the first direction being perpendicular to each other.
