A reconfigurable tool module for an end-effector includes an adjustable-height housing attached to a swing arm. The adjustable-height housing includes a valve spool and a flow path terminating at a workpiece interface tool. The valve spool is configured to interrupt the flow path when the adjustable-height housing is in a first position. The valve spool is configured to open the flow path when the adjustable-height housing moves away from the first position.

A reconfigurable pallet that supports a structure includes a base and a modular stanchion. The modular stanchion is magnetically attachable to the base along x and y axes relative to a top surface of the base. The modular stanchion includes a support element that has a height along a z axis that is transverse to the x and y axes. The support element supports the structure.

A reconfigurable pallet that supports a structure includes a pallet base and at least one track formed in the pallet base. A plurality of modular stanchions are supported on the pallet base and slidably engage the at least one track to selectively position the modular stanchions along x and y axes relative to a top surface of the pallet base. The modular stanchions each include a support element that has a height along a z axis that is transverse to the x and y axes. The support element supports the structure.

An adjustable length cylinder assembly includes a housing and a piston reciprocably mounted within the housing for movement between an extended position and a retracted position. The piston defines first and second hydraulic fluid chambers of differing cross-sectional area on opposite sides of the piston. An accumulator is housed within one of the housing and the piston. Channels communicate hydraulic fluid the first and second chambers and the accumulator during the movement of the piston. A valve member is concentric with the piston and accumulator and rotatable between a first rotary position in which the channels are open so that fluid can be transferred between the chambers to allow retracting and extending movement of the piston and a second rotary position in which the channels are closed so that fluid cannot be transferred and the piston is locked against retracting and extending movement.

A bayonet collet pickup tool includes a collet chuck having a collet portion including a bore disposed therein. A collet is held in the bore and is operable therein. A bayonet cap is mounted to an outer surface of the collet chuck proximate the bore. The bayonet cap includes a tubular socket concentric with the bore, at least one pair of diametrically opposed linear slots adjacent the socket, and a circular ledge adjacent the socket and perpendicular to the slots. A part including a shaft and at least one pair of diametrically opposed pins projecting from the shaft is receivable in the bayonet cap and the bore. Rotating the collet chuck while the pins are level with the ledge and then closing the collet releasably retains the part in the tool.

A reconfigurable pallet that supports a structure includes a pallet base and a plurality of modular stanchions that are adhesively secured to the pallet base. The modular stanchions are selectively positionable along x and y axes relative to a top surface of the pallet base. The modular stanchions each include a support element that has a height along a z axis that is transverse to the x and y axes. The support element supports the structure.

A mechanism for honing non round cylinder bores includes a tool body rotatable around a nonrotatable cam with a non round peripheral cam surface and a plurality of honing stones carried by supports for generally radial movement in the tool body. In a preferred embodiment, the supports are swing arms pivotally mounted so that the honing stones follow generally radially oriented arcuate paths determined by cam followers carried by the swing arms. A separately controlled expansion actuating rod axially adjusts expansion shoes that wedge outward stone shoes carried by the swing arms to progressively remove stock from the cylinder and to compensate for wear of the honing stones. Assembly with an associated machine adapter supports the honing mechanism and connects with a conventional honing machine to drive and orient the assembly for accurately honing non round cylinder bores.
