摘要： A device for the control of the thrust force of a pneumatic screw driver movingly suspended on a holding device. The device includes a drive means for the application of a lifting force opposing the weight force of the pneumatic screw driver. Furthermore the device possesses control means able to produce a reduction or switching off of the lifting force due to the drive means when there is a certain drop of the operating pressure of the pneumatic screw driver.

摘要： An assembly machine includes a support structure having a plurality of selectively moveable support members that facilitate manually manipulating a tool relative to a work piece. A controller continuously gathers position information regarding the support members to determine every position of the tool. The controller includes a teach mode that allows for storing selected tool activation positions in particular sequences for subsequent control of the tool according to necessary procedures for completing a variety of assembly processes. One example machine designed according to this invention includes selectively controlled biasing members that maintain a zero balance on the tool, provide an operator assist to moving the tool or both.

摘要： An articulated support for a manually-operated power tool, such as a manually-positioned and trigger-operated tool having a driven rotary spindle for engagement with a work, includes a plurality of elongated segments that are connected by articulating joints to thereby define several relative joint angles. Angle sensors at the joints generate relative angle information that is used by a controller to determine when the tool has been placed in a position, relative to either the support's fixed base or the work, in which a selected tool operation is likely to be performed successfully. Thereafter, the controller enables trigger-operation of the tool, monitors the length of time that the selected tool operation is performed, and, preferably, determines the likelihood of a successful completion of the operation based at least in part on the monitoring.

摘要： A maneuverable power jaw apparatus for making and breaking joints of well bore tubulars is provided for operation on a rig floor. Preferably a plurality of wheels are mounted to a mobile housing in a reverse tricycle orientation that permits high maneuverability of the mobile housing including rotation in position. Preferably, the two forward wheels are individually powered by hydraulic motors. Vertical orientation of the mobile housing is preferably provided by hydraulic struts that, once the mobile housing is positioned adjacent the pipes on the rig floor, permit the power jaws to be positioned at the correct vertical position on the joints for making, breaking, and spinning of the pipes. In one presently preferred embodiment, a pivotal connection is provided between the mobile housing and a frame to which torque arms are attached. In this embodiment, the frame rotates with respect to the well bore tubulars as the joints are made or broken while the mobile housing may remain stationary.

摘要： An automatic fastener feed system provides a nut, bolt or other fastener to a movable drive tool such that the fastener is automatically engaged with a drive member on the drive tool and subsequently driven onto a corresponding fastener on a work piece. The feed system includes a fastener acceptor which is adapted for connection to a parts feeder via a supply line. The parts feeder provides the fasteners to the fastener acceptor, which at least temporarily retains the fastener in a position for engagement with the drive member. As the drive member rotates and moves through the fastener acceptor toward a mating fastener on a work piece, the fastener within the fastener acceptor is automatically aligned and engaged with the mating fastener as the drive member is rotatably driven by the drive tool. Continued operation of the drive member causes the fastener acceptor to release the fastener, thereby allowing the fastener to be driven completely onto the mating fastener on the work piece.
