A method and rivet apparatus comprise a rivet block, the rivet block comprising a rivet block, a pin bore, and a rivet feed bore. The rivet block is comprised of a top end and a bottom end. The pin bore includes a top end and a bottom end and is disposed within the rivet block. The pin bore extends from the top end to the bottom end of the rivet block and guides a rivet pin that slides downward within the pin bore to push a head of a rivet into a workpiece. The rivet feed bore includes a top end and a bottom end and is disposed within the rivet block. The rivet feed bore extends from the top end to the bottom end of the rivet block, accepts the rivet at the top end of the rivet feed bore, and guides the rivet to the bottom end of the rivet feed bore. The rivet feed bore intersecting the pin bore between the top end and the bottom end of the pin bore at an oblique angle.

A central chuck including a chuck base, a first chuck and a first drill bit. The first chuck is rotatably coupled to the chuck base and has a chuck bore terminating at a lower chuck wall and a transverse locking bore. A locking plug is threaded into the transverse locking bore. The first drill bit has an upper portion, a central portion and a distal end. The upper portion has a smaller diameter than the central portion with a shoulder spanning between the upper portion and the central portion. An oblique plane defined in the upper portion inclined in a downward and inward direction toward the shoulder. Threaded insertion of the locking plug into the chuck bore interfaces with the drill bit and directs the drill bit in an upward direction and forces the shoulder into tight abutment with the lower chuck wall.

A lower drill tool that is structurally configured to receive a bracket, and, to cooperate with an upper drill tool having a pair of spaced apart drill bits. The lower drill tool has part receiving surface, a pair of spaced apart drill bores, a central bore, a centering nub and a biasing member. The drill bores extend downwardly away from the part receiving surface. The central bore is between the drill bores and extends downwardly away from the part receiving surface. The centering nub is slidable within the central bore, and has an upper tip extendable beyond the part receiving surface, positionable between an extended position and a partially retracted position. The upper tip has a conical configuration. The biasing member is positioned within the central bore and biases the centering nub toward the extended position. A drill system and a method are also disclosed.

A handle is coupled to an industrial machine tool, along with a method of operating the industrial machine tool via the handle. The handle comprises a housing, a first switch, and a second switch. The housing includes a first side, a second side, a top end, and a bottom end, the first side facing toward the industrial machine tool and the second side facing away from the industrial machine tool. The first switch actuates a float mode for the industrial machine tool, the float mode being a mode in which movement of a moveable portion of the industrial machine tool is power assisted for an operator of the industrial machine tool. The second switch actuates a machining portion, coupled to the moveable portion of the industrial machine tool, to perform a machining process on a workpiece.

An upper drill tool including a central chuck, an upper component, a lower component and a coupling assembly. The central chuck has a chuck base and a chuck structurally configured to retain a drill bit. The upper component is attached to the central chuck and has a lower stop surface. The lower component has a central body and an outer ring that threadedly engages the central body, with the outer ring having an upper stop. The coupling assembly is configured to facilitate the slidable movement of the lower component from a first orientation wherein the upper stop is spaced apart from the lower stop surface and a second orientation wherein the upper stop is in abutting engagement with the lower stop surface, with the first orientation and the second orientation defining a stroke.

The present invention relates to an additive manufacturing system and its methods. The system includes a material conveyor, an energy source, and a micro-forging device. The material conveyor is configured to convey material. The energy source is configured to direct an energy beam toward the material, the energy beam fuses at least a portion of the material to form a solidified portion. The micro-forging device is movable along with the material conveyor for forging the solidified portion, wherein the micro-forging device comprises a first forging hammer and a second forging hammer, the first forging hammer is configured to impact the solidified portion to generate a first deformation, and the second forging hammer is configured to impact the solidified portion to generate a second deformation greater than the first deformation.
