  • the present invention is therefore based on the object, a carrier head for the To provide a workpiece receiving a quick and easy change between its reference position and its measuring air position.
  • the carrier head for receiving a workpiece has a fastening device for fastening the carrier head on a Support column or the like of a support system and a contact surface for Plant a workpiece.
  • the carrier head of a Fastening device having lower part and a contact surface having the upper part is constructed, wherein the upper part and the lower part of each other are separable; and also a plate is provided, optionally between the Lower part and the upper part can be interposed, wherein the contact surface of the Carrier head with intermediate plate in a reference position for contacting of the workpiece is and the contact surface of the carrier head without interposed plate in a measuring air position to provide a preferably defined distance to the workpiece is located.
  • the Contact surface having upper part of the carrier head interchangeable without the entire carrier head needs to be changed, and secondly, a plate be interposed or removed, thereby quickly and easily between a reference position in which the workpiece on the contact surface of Carrier head rests, and a measuring air position, in which between the contact surface the carrier head and the workpiece a defined distance (measuring air gap) is provided to measure the workpiece at this point, can be changed. Due to the fast change between reference position and Measuring air position can be the one required for the measurement of the entire workpiece Time can be significantly reduced.
  • the plate is on a holder, which on the Bottom part or the upper part is attached, attached in such a way that it is optional between the lower part and the upper part can be pivoted in and swung out.
  • the Plate is thus captive mounted on the carrier head and can by a easy swiveling movement between reference position and measuring air position change.
  • the contact surface of the carrier head adjustable trained.
  • the carrier head further comprises at least one to the contact surface opening channel, which is connectable to a vacuum source, so that the Workpiece without mechanical clamping devices or the like against the Contact surface of the carrier head can be pressed or sucked.
  • the carrier head can be a measuring device, for example in the form of a measuring ball have at a defined position of the carrier head, with which the position of the Carrier head can be checked.
  • the mounting system includes a base plate 10, for example, on a Base plate 12 of a (not shown) coordinate measuring device in one is arranged predetermined position.
  • a base plate 10 On the base plate 10 are several Support columns 14, for example in the form of aluminum hollow profiles with square Cross-section, reproducibly arranged at defined positions.
  • Support columns 14 With the Reference numeral 16 denotes various cross braces, with which the Support columns 14 are stabilized in particular with a resting workpiece should.
  • the attachment of the support columns 14 to the base plate 10 is not subject matter The present invention, which is why not discussed here at this point shall be.
  • the invention is not limited to a particular type of attachment the support columns 14 restricted; an example of an advantageous attachment of Support columns 14 on the base plate 10 is in the already mentioned above DE 299 11 395 U1 described in detail.
  • a carrier head 18 is mounted, for example by means of Fastened screws. On the abutment surfaces (described later) of the carrier heads 18 If there is a workpiece 20 to be measured.
  • the workpiece 20 may be, for example pressed sheet metal body part or one of a plastic material be made molded part.
  • the carrier heads 18 may further at least one of their Have contact surface opening channel 22 which at the workpiece 20th remote side with a vacuum source (not shown) is connectable. For this is guided through the interior of the support column 14, a vacuum line, with a suction port 24 is connected at the lower end portion of the support column 14. On This way, a workpiece to be measured 20 by means of negative pressure to the Contact surfaces of the carrier heads 18 deformation-free and without mechanical Clamping devices are sucked.
  • contact surfaces of the carrier heads 18 with a protruding Mandrel 26 or the like may be provided in a corresponding hole or Recess engages in the workpiece 20 to be measured.
  • the carrier head 18 constructed according to the invention of a lower part 28 and an upper part 30. While the upper part 30 of the carrier head 18 in particular the contact surface for receiving the Workpiece 20, the lower part with a fastening device for Attachment of the carrier head 18 on a support column 14 is provided.
  • the Fastening device consists for example of a base 32, in which several Holes 34 are formed, with threaded holes in the top of a Support column 14 are aligned and through which screws into the threaded holes of the Support column 14 are screwed.
  • the lower part 28 and the upper part 30 of the Carrier head 18 separable from each other.
  • the upper part 30 with the contact surface for the workpiece 20 easily replaceable, without the to change the entire carrier head 18.
  • the upper part 30 and the lower part 28 each with a pin 36 and 38 and a bore (not visible in Figure 2) provided.
  • the pins 36, 38 of the one Component of upper part 30 and lower part 28 respectively fit into the associated bore of the other component of upper part 30 and lower part 28.
  • These pins 36, 38 and holes form a positioning device with which the relative position between the upper part 30 and Lower part 28 of the carrier head 18 is fixed against rotation.
  • a bolt 40 provided in the direction of the bore is biased and provided with a frontal projection, which in the Ring grooves 42 of the associated pin 36 on the upper part 30 of the carrier head 18th can engage, so that the pin 36 can be releasably locked in the bore.
