A rod pulling device for pulling a rod anchored in surrounding material, the rod pulling device comprising: a substantially elongated device body; a carriage movable along the device body; an actuator operatively coupled to the carriage for selectively moving the carriage along the device body; and a gripping assembly mounted to the carriage for selectively gripping the rod; wherein the gripping assembly includes a pair of jaws each defining a respective gripping surface for gripping the rod, the gripping surfaces facing each other and defining a gap therebetween for receiving the rod, the jaws being movable between open and closed configurations, wherein the gap is narrower in the closed configuration than in the open configuration.

A horizontal assembly press apparatus for performing a press-fit operation of a workpiece assembly along a horizontal axis includes a machine body unit, two moving units, two camera units, two pressing bed units and a processing unit. The machine body unit includes two main machine bodies defining an operating channel therebetween. The moving units are respectively and movably disposed on the main machine bodies. The camera units fetch images of the workpiece assembly entered the operating channel and output image signals. The pressing bed units are operated to press the workpiece assembly. The processing unit receives and analyzes the image signals, determines a target position of the horizontal axis, controls movement of the moving units to bring the pressing bed units to the target position, and controls movement of the pressing bed units to perform the press-fit operation of the workpiece assembly.

A press frame for a robot system includes a base, a bridge and a set of columns supporting the bridge above the base. A first robot holds a part on the base and a second robot manipulates a pressing tool to press a component into an opening. The pressing tool is backed by the bridge that opposes a reaction force resulting from pressing the component part into the part. A method of assembling components to a part by pressing the part into an opening while engaging the bridge of a reaction frame. The part is transferred to the base by a first robot that positions the part on the base. A pressing tool and a component are selected by a second robot that orients the component to be inserted in the opening. Data relating to displacement, load and time is collected by the controller.

A flexible pressing system for accepting and rejecting pressed part into a part may include a pressing apparatus configured to press components into a hole of a part and a controller programmed to receive press data for a press of at least one of the components, the press data including force, distance and time of the press, and determine whether the force is indicative of an inadequate press based on the force and distance at a specific time of the press.

An integrated control system for a flexible pressing system may include a first robot including a gripper for manipulating a part, a second robot including a pressing tool, and a controller configured to instruct the first robot to move the part into a pressing position and to instruct the second robot to concurrently ready the pressing tool for pressing.

A method for mounting rotor blades on a rotor disk along a predetermined pitch circle diameter in such a way that adjacent rotor blades, when properly mounted on the rotor disk and in the cold state, are clamped against each other with a predetermined preload. A clamping device which performs such a method has a plurality of clamping elements which are arranged in a uniformly distributed manner around a central axis, the number of which corresponds to the number of rotor blades to be mounted on the rotor disk and which in each case are designed for the locating of a rotor blade, wherein the clamping elements are moveable radially, exerting a radially inwardly directed force.

A hub puller kit for pulling hubs off of power ends of frac pumps, and a method of removing a hub from a pinion shaft of a power end using the hub puller kit. The hub puller kit has an adapter flange formed out of a monolithic body with fastener openings, and a hydraulic actuator coupled to the adapter flange. The adapter flange has a stepped surface formed on a first surface and a recessed surface formed in a second surface, and a central opening having a threaded flange portion that extends from the stepped surface to the recessed surface. The hydraulic actuator has a hydraulic cylinder and a hydraulic plunger disposed at least partially within the hydraulic cylinder, and a threaded actuator portion that engages the threaded flange portion to couple the hydraulic actuator to the adapter flange.
