Electric-hydraulic riveter and lockbolt hand power tool
An electrically-hydraulically powered riveter and lockbolt hand power tool is provided, having a battery driven electric motor mechanically powering an offset drive cam through a dual planetary drive gear, the drive cam being in direct mechanical contact with a single stage concentrically delivering longitudinally reciprocating piston pump being in direct hydraulic communication with a work engaging hydraulic cylinder surrounding a centrally fixed and stationary work engaging cylinder piston having a work piece puller shaft, wherein the work engaging hydraulic cylinder is thrust forward around the work piece puller shaft when the tool is activated thereby providing the mechanical motion to activate a user provided riveter nose assembly attachment. A multi-function valve provides essential hydraulic pump features integrated into a single simple component including over pressure relief, isolation of the work engaging cylinder cavity during pumping, and venting when the tool is deactivated.
RIVETING APPARATUS FOR ASSEMBLY PLANTS
A riveting apparatus for application and riveting a rivet to a component of an article being processed in a work region of the riveting apparatus is provided. The riveting apparatus includes a rivet insertion device for insertion of the rivet into the component and a riveting device for the riveting of the rivet.

Method of riveting
A method of inserting a rivet into a workpiece comprises moving the rivet and workpiece relative to one another, along a longitudinal axis of the rivet, so as to drive the rivet into the workpiece. The rivet is rotated about its longitudinal axis, relative to the workpiece, for at least part of the time during which it is in contact with the workpiece. The speed of said rotation, or the speed of movement along the longitudinal axis of the rivet, is altered at least once before driving of the rivet into the workpiece is complete. One axial end of the rivet has a tip for piercing the workpiece, and the rivet has a substantially cylindrical shank extending longitudinally from the tip. The shank has one or more surface irregularities.

Regulator for a power tool
A regulator for a power tool for tightening a fastener in order to unite two or more pieces into a joint. The regulator regulates the power tool when tightening the fastener such that the fastener is tightened to a predetermined target. The regulator calculates an output signal to the power tool, which output signal is based on the product of the torque exerted by the power tool on the fastener and the angle for turning the fastener about its axis. The output signal is used for tightening the fastener to the predetermined target. The regulator is also applicable to a power tool for a rivet joint.

SETTING UNIT AND METHOD FOR SETTING A CONNECTING UNIT ON A WORKPIECE
A setting unit and a method for setting a connecting element on a work piece. The setting unit has a hold-down clamp. A punch is displaceably mounted in the hold-down clamp, is drivable in a feed direction by way of a plunger and has a front punch head, and a punch sleeve which surrounds the punch head. The punch sleeve is movable together with the punch in the feed direction to a first stroke position. The punch head is movable relative to the punch sleeve to a second stroke position such that it is possible to carry out both a hole punching operation and a setting operation by way of the one punch in connection with the punch sleeve.

Fastening tool
A fastening tool includes a housing, a handle, an anvil, a pin-gripping part, a motor, and a driving mechanism. The driving mechanism is configured to move the pin-gripping part along a first axis defining a front-rear direction, relative to the anvil. The driving mechanism includes a rotary member, a movable member, a driving gear and an idler gear. The rotary member has a driven gear formed on its outer periphery and is rotatable around the first axis. The movable member is connected to the pin-gripping part and configured to be linearly moved in the front-rear direction by rotation of the rotary member. The driving gear is configured to be rotated around a second axis extending in parallel to the first axis below the first axis. The idler gear is engaged with the driving gear and the driven gear.
