  • Patent number: 7530557
    Abstract: A multi-axis chuck that rotates about at least two axes. Preferably, the axes are perpendicular. The multi-axis chuck includes a first portion, second portion, and third portion. Rear sides of the first portion and the second portion have a first mating portion that mates with a second mating portion provided on the second portion and the third portion, respectively. The mating portions enable the first portion and the second portion to be rotated about the axes. Preferably, the first portion rotates about a first axis independently of the second and third portions. Rotation of the second portion about a second axis preferably also rotates the first portion about the second axis. The multi-chuck is operatively connected to a motor, controller, and sensors. A user inputs a desired position into the controller that controls the motor. The motor rotates the multi-axis chuck to the desired position. The sensors are used to determine a position of the multi-axis chuck.

  • Patent number: 6948720
    Abstract: A computer controlled positioning table for use in automatically rotating a large diameter article into which an evenly spaced circle of bolt holes are to be drilled. The article to be drilled is centered and clamped onto a table top of the table and then the computer rotates the table top incrementally to precisely position the article relative to an associated stationary drill stand that is used to drill the desired holes in the article. Rotation of the table top is computer controlled, allowing the operator to select the number of bolt holes for each article. Once the table top has rotated to the proper position, locking mechanisms and support roller provided under the table top hold the table top stationary in the proper position while a hole is drilled in the article.

  • Patent number: 6772493
    Abstract: A workpiece changing system capable of automatically changing a heavy workpiece using a robot. A jig for attaching a workpiece thereto is mounted on a jig mounting device. The jig mounting device comprises a jig mounting unit having a rotary member and a swing member. The rotary member rotates the jig and the workpiece on the jig and hold them at a desired rotary position. The tilting member swings around an axis to tilt the jig and the workpiece on the jig and hold them at a desired tilting position. As the jig and the workpiece on the jig can take a suitable orientation or posture for being handled by the handling robot, the handling robot can hold a heavy workpiece without exerting excessive load on the robot wrist.

  • Patent number: 6240807
    Abstract: An indexing apparatus for selectively indexing a payload about an axis. The apparatus includes a housing that supports an indexable support table. A second retainer is provided on the indexable support table that is adapted to selectively axially engage a first retainer on the housing to lock the indexable support table in any one of a plurality of selected rotational positions about the axis. The apparatus also includes an axial displacement member that is movably supported within the housing to selectively engage the indexable support table while the indexable support table is locked in any one of the preselected rotational positions. Thereafter, the axial displacement member biases the indexable support table in a first axial direction out of the locked position and applies a rotational force to the indexable support table to rotate it a desired amount about the axis.

  • Patent number: 6092796
    Abstract: A work piece holding mechanism which provides multi position part holding capability to automatically sequentially hold and present a work pieces in multiple orientations for work thereon. The work piece holding mechanism includes two rotatable clamp means for clamping the work piece therebetween. Rotation of at least one of the rotary clamps is driven by a rotary drive mechanism, preferably a rotary air cylinder. The rotary air cylinder is provided with at least one fixed rotational stop. In addition, the rotary air cylinder may be provided with one or more actuatable intermediate stops. Rotation of the work piece can be accomplished by driving the rotary air cylinder to a predetermined position against either a fixed stop or an actuatable stop. Each of such stop positions results in a different orientation of the work piece and thus a different work plane on which the robot can operate.
