Abstract
A coordinate measurement device comprises an articulated arm having a first end, a second end, and a plurality of jointed arm segments therebetween. Each arm segment defines at least one axis of rotation. A laser scanner assembly is coupled to the second end of the arm and is rotatable about a last axis of rotation of the articulated arm. The laser scanner assembly comprises a laser and an image sensor. The laser is positioned on an opposite side of the last axis of rotation from the image sensor.
Claims8
An articulated arm CMM system comprising:
- an articulated arm CMM comprising a plurality of articulated arm members rotatably connected to each other, a plurality of sensors configured to measure rotational positions of the articulated arm members, a receiving portion and a distal end, and a base portion at a proximal end, the receiving portion comprising:
- a recess shaped to receive a laser;
- and
- an arm data port;
- and
- an optical position detecting device configured to mount to the receiving portion of the articulated arm CMM, the optical position detecting device comprising:
- a laser shaped to be received within the recess;
- and
- a device data port configured to engage with the arm data port to provide a data connection between the optical position detecting device and the arm.
An optical position detecting device configured to mount to an articulated arm CMM, the optical position detecting device comprising:
- a laser extending from the optical position detecting device;
- an optical sensor configured to receive light from the laser;
- a data port configured to engage with a corresponding data port on a distal end of an articulated arm CMM to which the optical position detecting device is configured to mount;
- and
- a portion of a snap-lock mechanism configured to engage with a portion of a snap-lock mechanism on the distal end of the articulated arm CMM to which the optical position detecting device is configured to mount, such that the optical position detecting device can form a snap-lock with the distal end of the articulated arm CMM.
A method of mounting an optical position detecting device to an articulated arm CMM, the method comprising:
- aligning a data port on the optical position detecting device with a data port on the articulated arm CMM;
- aligning a laser extending from the optical position detecting device with a recess in the articulated arm CMM configured to receive a laser;
- attaching the optical position detecting device to the articulated arm CMM such that the data ports engage to form a data connection and the laser is received in the recess;
- and
- measuring one or more coordinates with the articulated arm CMM and the optical position detecting device.
