Patent number: 6241645Abstract: A magazine which retains tools within the working area of a machine tool has a storage port which is mounted to a base via a compliant mount which provides two degrees of rotational freedom, and two degrees of translational freedom. The mount enables the storage port to be brought into register with a chuck on the spindle of the machine as a result of mutual engagement between surfaces on the storage port and the chuck during a tool change operation. The tool is retained within the chuck by using hydraulic pressure chambers in the chuck to deform an interior wall of the chuck cavity, and thereby causing it to grip the sides of the tool. Such a retention mechanism requires a relatively small clearance of the tool within the chuck when the wall is underformed, thereby necessitating the compliantly mounted storage port and alignment surfaces.Type: GrantFiled: January 12, 2000Date of Patent: June 5, 2001Assignee: Renishaw PLCInventor: Gregory S Vanhinsbergh

Patent number: 5993365Abstract: A tool attachment and release system for robotic arms which using a magnet for supplying the attractive force to hold the tool to the robotic arm while allowing separation of tools from the robotic arm without manual intervention. A series of tools are held at predetermined locations in a tool rack allowing the robot to automatically deposit therein or acquire therefrom a particular tool. Permanent magnets are mounted between steel inserts in the tool attachment block. The steel insert are used to direct and concentrate magnetic flux to the tool attachment surface and also to each of two shunt bar contact surfaces. During the attach and disconnect operations, magnetic flux shunt bars are placed in close proximity to the two shunt bar contact surfaces to thereby provide an alternative path for the magnetic flux. This greatly reduces but does not eliminate the attractive force between the tool adapter plate and the attachment block.Type: GrantFiled: March 26, 1998Date of Patent: November 30, 1999Assignee: Eastman Kodak CompanyInventors: Joseph E.

Patent number: 5971903Abstract: A system is disclosed enabling the automated exchange of touch probes (34,38) on an articulating probe head 40. The touch probes are mounted to adaptors 32, and are housed in storage ports 20 of a magazine. An adaptor 32 is repeatably located upon the retaining module by the mutual engagement of kinematic support elements 50,52 on the probe head 40 and adaptor 32 respectively. The support elements 50,52 are urged into mutual engagement by a locking mechanism having a spigot 60 on the probe head 40 which engages a cam 62 on the adaptor 32; rotation of the cam 62 locks/unlocks the support elements into mutual engagement. During an exchange operation the cam 62 is rotated by a screwdriver 80 in the storage port. Rotation of the screwdriver 80 is caused by relative movement of the storage port and the support plate 14, which is part of the support structure of the magazine.Type: GrantFiled: January 22, 1998Date of Patent: October 26, 1999Assignee: Renishaw PLCInventor: Peter Hajdukiewicz

Patent number: 5825666Abstract: The optical touch probe has a first target at the distal end thereof on the contact element in a standard probe. The probe is mounted to a video camera of an optical coordinate measuring machine to image the target on the camera. Movement and position of the target in the X and Y coordinates is indicated by the machine's computer image processing system. A second target is mounted to the proximal end of the probe and indicates movement and position in the Z coordinate. The second target may obscure a photodetector, but preferably is parfocused on the camera by light beam parallel to the X,Y plane. Preferably there are two second targets illuminated by orthogonal beams parallel to the X,Y plane. Rotation around the Z axis then may be calculated by the computer when star probes are used. Auto changing racks are also disclosed for holding multiple probes, a probe holder, and lenses for selective mounting on the camera.Type: GrantFiled: June 7, 1995Date of Patent: October 20, 1998Inventor: Daniel Freifeld

Patent number: 5820538Abstract: In a tool changer system comprising one or more tool grippers together with a pressure foot insert change pod supported on a U-V slide which is independent of the machine work table. The slide services a tool magazine mounted on the machine tool in close proximity to the work table. Because the tool changer is independent of the machine table, the selection and retrieval of the next tool to be used is performed while the machine tool is working. Similarly, the replacement of the tool back into its storage location is done while the machine tool is working. The exchanging of the pressure foot insert is done as part of the tool change process. Time is saved because the work table does not have to be moved to position the tool changer under the spindle. In fact, the work table may be moved to the next work location while the tool changer changes the tool in the spindle.Type: GrantFiled: April 22, 1997Date of Patent: October 13, 1998Assignee: Excellon Automation CompanyInventor: Robert J.

Patent number: 5256128Abstract: Methods and apparatus for exchanging the end effectors of apparatus for handling objects, such as robotic manipulators are disclosed. A compliant tool depository is used in conjunction with a tool holder to perform the end effector exchange. The present invention utilizes the motive force provided by the end effector actuation to execute the sequence required for end effector exchange. A bi-stable latch is provided which minimizes the force required to latch and unlatch the end effectors, thereby providing an end effector exchange mechanism useful in small laboratory robots possessing small operating forces. The tool depository design also adds to the positional forgiveness of the apparatus, allowing the robotic arm and the depository to be aligned with a lesser degree of precision than might otherwise be required.Type: GrantFiled: April 20, 1992Date of Patent: October 26, 1993Assignee: Hewlett-Packard CompanyInventor: Hans D.
