Abstract
A five-axis spatial precision measurement fixture includes a body and a base. The body has a first side, a second side and a third side. The first side is parallel to a first direction and has two opposite ends connecting to the second side and the third side. The included angles between the first side and the second side and third side respectively are 45 degrees. The included angle between the second side and the third side is 90 degrees. At least three mounting holes are provided on a first surface of the body to install a sphere respectively. A center line of the at least three mounting holes is parallel to the first direction, and distances between centers of any two adjacent mounting holes are the same. The body is pivotably disposed on the base and mounted on the working table of the five-axis machine tool.
