摘要:
A conventional blind rivet tool with modified nose housing, i.e., a rivet gun with replaceable and interchangeable nosepieces, facilitates feeding and setting of multiple diameters of blind rivets with substantially shortened exposed mandrel portions extending beyond the head flange of the rivet, all while maintaining blind rivet performance and reducing total installed blind rivet costs. A rivet with a reduced exposed mandrel protrusion relative to conventional and standardized mandrels can be enabled and more easily fed through the tool.

A method for crimping an insert to be clinched in a support by means of a placing apparatus having an anvil, in an area where the support comprises superposed first and second panels at a distance from one another, wherein the shank is inserted axially in the support and the anvil is brought up against the distal end of the shank, and the second section is then axially compressed against the anvil to create a securing edge, axial compression of the second section then being continued to create a crimping rim delineating an anchoring groove, in combination with the securing edge, surrounding the second panel, axial compression of the second section then being continued to bring about clamping of the support between the securing head and the securing edge in conjunction with clamping of the second panel between the securing edge and the crimping rim.

A rivet fastening air tool for rivets includes a supplying actuator, an implanting actuator, and a switching valve. The supply actuator receives a rivet row, tears off a fragile portion of a front-row rivet, and supplies it in a loaded position. The implanting actuator retains a head portion of the rivet supplied in the loaded position, and moves the rivet in a direction of being pulled out of a communicating bore of the rivet. The switching valve is provided in an air supply route which reaches the supplying actuator. When the head portion of the rivet is moved in the direction of being pulled out, the switching valve is switched by the implanting actuator so that the supplying actuator is returned.

A rivet table connected to the nosepiece of a rivet setting apparatus. The rivet table includes an outer sleeve which controllably slides back and forth within the nosepiece and supports opposing jaws pivotally connected to the outer sleeve about spaced transverse pivot axes. The jaws pivot between a closed position and an open position, biased toward the closed position and define a flat transverse distal rivet head receiving surface, and a central mandrel-receiving aperture therebetween to slidably receive a rivet mandrel and to support the rivet head against said rivet head receiving surface during rivet setting. The jaws are momentarily forced into the open position by the mandrel moving laterally into the aperture and being carried on a flexible strip. The exposed surface of the rivet head is thereby substantially free of tool marks after being set.

A driving anvil washer retaining apparatus (12) for a rivet gun (14) includes a magnetized element (21). The magnetized element (21) is coupled to the rivet gun (14) and retains an anvil washer (52) during installation of a rivet (82). A method of installing a rivet (82) includes inserting a stem (46) of a rivet assembly (80) into a rivet gun nose (22) having at least one magnetized portion (21). A rivet (82) of the rivet assembly (80) is inserted into at least one object. The stem (46) is removed from the rivet assembly (80). A driving anvil washer (52) is retained via the magnetized portion (21).
摘要:
A blind fastener installation tool which accomplishes the blind installation of a series of fasteners is described in detail in this specification. The blind fastener installation tool comprises a structural housing which features a means for securing a fastener installation assembly in position relative to said structural housing during the blind installation of a fastener; and a means for reciprocating said fastener installation assembly relative to said structural housing at the conclusion of a cyclic blowline-fed or clip-fed blind installation of a fastener. The blind fastener installation tool also comprises a fastener installation assembly comprising (1) a pull rod assembly comprising means for pulling a first portion of a fastener; (2) an annular, piston-actuated, direct action, piston-decoupled pull rod actuation assembly to translate the pull rod assembly relative to said fastener installation assembly when said fastener installation assembly is secured at a fastener installation assembly fastener installation position, thereby pulling said first portion of said fastener until blind installation of said fastener is complete; and (3) a nose assembly comprising (3a) a fastener receptacle for securing the position of a fastener relative to said nose assembly during blind installation of said fastener; and (3b) one or more optional pull rod translation dampening assemblies to smoothly and effectually dampen the sudden translation of said pull rod assembly after pintail break during blind installation of a pintail-break—type fastener. The blind fastener installation tool also comprises an optional fastener delivery assembly, said optional fastener delivery assembly constituting: (1) a clip-fed fastener delivery system; or (2) a blowline-fed fastener delivery system.
摘要:
A riveting system is operable to join two or more workplaces with a rivet. In another aspect of the present invention, a self-piercing rivet is employed. Still another aspect of the present invention employs an electronic control unit and one or more sensors to determine a riveting characteristic and/or an actuator characteristic.

A nail spacing verification assembly is provided which enables the spacing between nails contained in a collated nail strip, the collated nail strip advancing down a nail loading assembly of a nail gun, to be verified before the nail is allowed to advance. A first and second probe are operationally coupled with each other. If nail spacing is correct, the first probe engages the second probe causing both probes to rotate and the nail to pass. If spacing is incorrect, the first probe does not engage the second probe and the nail is hindered from advancing down a nail loading assembly.
摘要:
A center position device of a piston rod of a riveter primarily comprises a position device screwed on a threaded hole below a handle, wherein the position device comprises a pillar hole for being penetrated by a piston rod and a sealing ring fitted closely with the piston rod. A position ring, a ring trench, and a sealing ring are mounted to align the same centerline. At least two ring surfaces forms on an opening of the threaded hole of the handle to which the position device is screwed. When the position device is screwed to the threaded hole, the position ring of the position device touches closely with a ring surface. When the position device is screwed and fixed to the threaded hole of the handle, the centerline of the position will not suffer from deviation to prevent the accuracy of displacement of the piston rod from being affected.
摘要:
The subject of the invention is a device for assembly of several elements by riveting, the device including rivets or analogs, the shank of which has an elliptical or analogous cross-section placed and riveted in holes with an elliptical or analogous cross-section corresponding to that of the shank, laid out in the elements to be assembled. The invention also includes a method for assembling panels to make a fuselage of an aircraft.
