Abstract:

Apparatus for installing a rivet nut or the like having an intentionally threaded shaft wherein the apparatus includes a hydraulically geared power tool having an inner hydraulic fluid containing a chamber and a screw adapted to engage the threaded shaft of the nut wherein the power tool rotates the screw when actuated. A fluid outlet is coupled to the chamber and is coupled to a gauge controlled power supply, the power supply being fluidly coupled to the power tool whereby the power supply includes torque predetermining device for determining when a predetermined torque is placed on the screw, this stopping rotation thereof and resuming rotation in an opposite direction to withdraw the screw from the nut.

Abstract:

An insert installation apparatus comprises a housing having a body section and a nose piece. The nosepiece comprises a forward end and a rearward end, where the rearward end of the nose piece is attached to the body section. The apparatus comprises a rotary power source and reciprocating means which are employed to set a threaded insert in a work piece. The rotary power source has an extension member which connects the rotary power source to the first end of a drive shaft which is received by the extension member. The second end of the drive shaft is operationally coupled to a partially threaded mandrel which extends out of the forward end of the nose piece. The apparatus further comprises mandrel shock absorbing means which allow the mandrel to reciprocate with respect to the nose piece from a first position to a second position, where the mandrel shock absorbing means operates independently from the reciprocating means which usually employed to set the threaded insert. The mandrel shock absorbing means allows the threaded shaft to “give” if the tip of the mandrel impacts the crests of the threads of the insert as the tip is inserted into the opening of the insert. While a small spring or other biasing means are used to bias the threaded shaft forward the threaded shaft may be partially pushed back into the nose piece upon contact with the threads of the insert, thus preventing impact damage to the root thread of the insert and preventing cross-threading.

International Classification:

B21J015/00

US Classification:

Abstract:

A system is disclosed for installing an insert within an aperture in a workpiece, the workpiece having a first side and a second side. The insert is the type in which a portion of the insert plastically deforms on the second side of the workpiece upon application of a linear force provided by a tool, thereby preventing withdrawal of the insert from the aperture. The insert comprises a sleeve member and an integral flange, where the flange has a larger diameter than the aperture. The disclosed installation system performs two actions. It causes the expansion of the sleeve and it also causes the flange of the insert to be fused or welded to the first side of the workpiece. The welded connection between the insert and the workpiece prevents any rotation or spinning of the insert within the workpiece, and increases the integrity of the insert-fastener connection.
