ASSEMBLY FOR A MEASURING SYSTEM FOR TAKING MEASUREMENTS ON A MEASUREMENT OBJECT, AND METHOD FOR TAKING MEASUREMENTS ON A MEASUREMENT OBJECT USING A MEASURING SYSTEM

摘要

The invention relates to an assembly for a measuring system for taking measurements on a measurement object, comprising an articulated arm with joints, each of which has a joint axis, and link elements, which connect the joints in a serial articulated arm arrangement; a measuring arm with measuring arm joints, each of which has a measuring arm joint axis that extends coaxially to the joint axis of a paired joint of the articulated arm, rotary encoders, each of which is paired with one of the measuring arm joints, and measuring arm link elements, which connect the measuring arm joints in a serial measuring arm arrangement, wherein the measuring arm together with the articulated arm forms a parallel kinematic system, in which one end of the articulated arm is connected to one end of the measuring arm and the opposite end of the articulated arm is connected to the opposite end of the measuring arm; a measurement reference point, which is arranged on one of the link elements or on one of the measuring arm link elements paired with the link element and connected to same; wherein at least three of the rotary encoders are arranged between the end of the measuring arm and the measuring arm link element; and a measuring device, which is designed to determine a spatial position of the measurement reference point using measurement signals of the rotary encoders of the measuring arm joints. The invention additionally relates to a method for taking measurements on a measurement object using a measuring system.
