Ball-hinged coupling mechanism of locator based on three-dimensional force sensor

The invention relates to a ball-hinged coupling mechanism of a locator based on a three-dimensional force sensor, wherein a three-dimensional force sensor is arranged on a locator; a ball-hinged coupling unit is connected with the three-dimensional force sensor; a process ball head is hinged in the ball-hinged coupling unit; two laser tracker targets are symmetrically arranged on an upper surface of the ball-hinged coupling unit along a diameter direction; and a data wire of the three-dimensional force sensor is led out by a wiring hole of the three-dimensional force sensor on the side. The coupling mechanism integrates the ball-hinged coupling and the three-dimensional force sensor with the locator, achieves quick and accurate coupling of the plane and the locator and coordination control of the locator, not only improves production efficiency, but also reduces assembly stress greatly.
