  • Patent number: 5966798
    Abstract: A long length product is conveyed by a conveyor to a propulsion mechanism into contact therewith. The product is gripped by a first conveyor line vise and cut at its tailing end side into a specified dimension. The product is advanced by the propulsion mechanism against the conveying force of the conveyor and then gripped by the first conveyor line vise and machined. A series of these operations are iterated. Finally, the product is advanced to a second conveyor line side, where it is gripped by a second conveyor line vise and subjected to final machining with the propulsion mechanism retreated. Instead of using a process of cutting to cut the leading end side of the product to a specified dimension, the leading end side of the product may be put into contact with the stopper and fed by referencing the leading end of the product.

    Abstract: A high throughput drilling system for printed circuit board hole formation. Two spindles are disposed at each spindle station, doubling the number of holes produced in a given time period. Each spindle in connected to an overhead linear drive by a mini slide. A first set of the spindles, one for each spindle station, is driven by a first X axis linear drive. A second set is driven by a second X axis linear drive. The work piece table is elongated to support work pieces for all stations, and is supported by a set of bearing guides, with outrigger bearings coupled to the table by flexure mounts that relieve stress due to differential temperature expansion rates between the work piece table and the base table. High speed spindles are employed to obtain higher productivity, with larger holes routed by router tools, eliminating the need for stocking large drill sizes on the system tool changer.

The pocket cut and fastener bore receives a fastener such as a self-tapping screw which passes through the bore and into a second workpiece for forming a Joint between the two workpieces. The head of the fastener is held within the pocket cut in order to secure the joint. In one preferred form of the present invention, a workpiece system secures the workpiece in a predetermined position and forms the pocket cut and fastener bore into the workpiece. This preferred embodiment further comprises a bench-mounting system coupled to the workpiece system for securing the system to a bench. Using this embodiment of the present invention, the system can be mounted to a bench, and the workpiece can be brought to the system and held in position while the user forms the pocket cut and fastener bore.

  • Patent number: 5368538
    Abstract: A boring apparatus provided with feed and discharge roller conveyors for drilling holes in heavy steel structural shapes can be constructed so that at least one boring unit is transformable into a milling unit, the computer being programmed with a milling program. The mechanism for advancing the workpiece used for boring is thus used also for displacing the workpiece during milling so that milling tables upon which the workpiece must be clamped and the like need not be provided. The system also avoids the need to move the massive workpieces between boring/milling units.

  • Patent number: 5358018
    Abstract: An automatic machine for performing framing operations on a power pole. The machine is controlled by a programmable logic control and interchangeable programs are provided to control the operation of the machine according to a pole frame specification. Poles to be framed are received on a primary conveyor. The poles are sequentially scanned for length and position and are transferred in sequence to a longitudinal feed station where the poles are oriented on a first set of supports. An end of the pole is clamped to a movable carriage to maintain the pole orientation. The pole is fed through a rotatable tool ring by movement of the carriage. The tool ring supports tooling to perform the framing operation on the pole. The programmable logic control coordinates the movement of the carriage and the rotation of the tool ring to position the tools in the proper relation to the pole. Self centering supports are provided to center the longitudinal axis of the pole on the rotational axis of the tool ring.

  • Patent number: 5340247
    Abstract: A workcenter (10) comprises its supports (14a,b,c) which each carry a carriage (24a,b,c) movable along the supports by motors (30a,b,c) under central computer control (41). Each support is an aluminium extruded U-shaped section having four tracks (28) comprising steel strips (27) in slots (29). The carriage is likewise extruded having undercut slots (83) receiving the heads (92) of axles (90) which have eccentric stubs (96) on which bearing wheels (26) are journalled. Four wheels are so-mounted at each end of the carriage. The workcenter is adaptable between different modes of operation; overhang or cantilever by virtue of the profile of the supports.

  • Patent number: 5301405
    Abstract: The milling machine lathe attachment is attachable to an existing milling machine so as to eliminate the need for an operator owning both a milling machine and a lathe. It is designed to be mounted to the side of the milling machine and to be used without disturbing a setup in the associated vise. The attachment is also designed to be mounted to the front of a milling machine and allows the programming of the very point of single point tool contact so as to follow whatever contour or steps are desired. This type of cutting is not possible on a lathe with guaranteed accuracy, while on a milling machine it is quite feasible.

  • Patent number: 5281079
    Abstract: An automatic, moveable manipulator includes an arm supported on a carriage and holding at least one tool. Both the arm and the carriage can be moved under the control of signals transmitted from a remote location, such as a central controller, which signal is stored in a storage device. The manipulator further supports a reservoir for holding materials that can be used by the tool, for example to apply to the workpieces, such as fluids, fasteners, expendable materials, and the like. An automatic resupply system permits the manipulator to re-fill the reservoir, such as when it is emptied.

  • Patent number: 5209094
    Abstract: A machine combines metal rod chamfering and stamping operations into a single machining operation. Cutting the chamfer on the end of the rod is accomplished by a rotating cutting tool affixed to a chuck which rotates with a spindle about an axis co-linear with the axis of the workpiece. Both the chuck and the spindle contain a hollow bore along their rotational axes. This bore holds a stamping rod which is free to move axially within the spindle. A stamping impact unit is located at the opposite end of the spindle which acts upon the opposite end of the stamping rod. At the desired moment within the chamfering operation, the stamping rod is hammered into the end face of the workpiece by the impact unit. The imprint end of the stamping rod functions as a mechanical stop to locate the depth the workpiece is inserted into a clamping collet.
