Abstract

A coordinate measuring system having a quick disconnect is disclosed. The coordinate measuring system includes a multijointed arm having a first end and a plurality of transfer housings for generating signals indicating the position of the first end. A first locking device is mountable to a second end of the arm. The first locking device has a first surface which is removably received within a first opening in a housing. The housing is mountable to a support and includes a second opening for communicating with the first opening. A second locking device having a second surface is movably received within the second opening from an unlocked position to a locked position and constitutes a cam which rotates to engage the first locking device. The second surface engages the first surface in the locked position to prevent the first locking member from being removed from the first opening. The first and second surfaces are not engaged in the unlocked position so that the first locking member can be removed from the first opening. Multiple sets of first and second locking devices are disclosed.
