An adapter for use with a conventional installation tool normally used for installing blind rivets comprises a universal installer head which is attached to the tool by threading one end of it onto the head of the tool in alignment with the gripping and pulling jaws located within the tool. The other end of the installer head is made to engage the upper surface of a squash nut. A pull shaft has a threaded end for engagement with the internally threaded portion of a squash nut and a jaw engaging end for free passage through the hole in the installer head into the area within the tool where it is gripped and pulled by the jaws in the installation tool. For squash nuts of different sizes, different pull shafts may be used where the jaw engaging end is of the same external diameter but where the threaded end has a different size depending upon the size of the squash nut with which the pull shaft is intended to be used. The pull shaft is made to be fully released by the tool following the installation of each squash nut; so that it may be manually removed from an installed squash nut and manually inserted into the next squash nut to be installed, whereupon the tool with the universal installer head is placed over the jaw engaging end of the pull shaft to install the next squash nut.

A tool for placing threaded inserts, of the type comprising a threaded first part which is pulled towards a second part to place the insert, has a generally tubular body integral with a radially extending body handle. A rotatable sleeve within the rear part of the body carries a reciprocable and rotatable shaft, to the forward end of which is connected a screw which protrudes through an annular anvil. The rear of the shaft carries a rotatable cam which is integral with a radially extending cam handle and bears against a roller mounted in the sleeve. The cam handle can be used both to rotate the shaft and screw, and to rotate the cam so as to retract the screw with respect to the body of the tool.

A MANUALLY OPERABLE TOOL FOR INSTALLING BLIND ANCHOR NUTS HAS A THREADED MANDREL WHICH CAN BE ROTATED BY A SHAFT HAVING AT ONE END A KEY ENGAGING A SOCKET ON THE MANDREL AND AT THE OTHER END A PROJECTING HANDLE. THE SHAFT IS BOTH ROTATABLE AND RECIPROCABLE, SO THAT THE KEY CAN BE DISENGAGED FROM THE MANDREL TO ALL ROTATION OF THE MANDREL IN SUCCESSIVE STEPS BY REPEATED ROTATION OF THE HANDLE THROUGH A SMALL ANGLE. THE MANDREL, THE KEY, AND AN ANVIL SURROUNDING THE MANDREL, MAY BE REMOVABLE AND INTERCHANGEABLE.

THE METHOD OF SECURING A SLEEVE TO A WORKPIECE IN WHICH THE SLEEVE IS PROVIDED WITH A FIRST ABUTMENT AT ONE END AND IS INSERTED INTO AN OPENING IN THE WORKPIECE SO AS TO BRING THE FIRST ABUTMENT INTO ADJACENCY WITH A SURFACE OF THE WORKPIECE. A GRIPPING MEMBER HAVING A SECOND ABUTMENT AND A SHANK IS EXTENDED THROUGH THE SLEEVE SO THAT THE SECOND ABUTMENT ENGAGES THE SLEEVE AND THE SHANK PROJECTS BEYOND THE OPPOSITE SLEEVE END, A TENSION THEN BEING APPLIED TO THE SHANK TO HOLD THE FIRST ABUTMENT FIRMLY AGAINST THE WORKPIECE SURFACE, WHILE SIMULTANEOUSLY THE OPPOSITE END OF THE SLEEVE IS BENT OUTWARDLY TO FORM AN OVERLAPPING FLANGE COOPERATING WITH THE FIRST ABUTMENT TO SECURE THE SLEEVE TO THE WORKPIECE.

A tool-change station includes a base, and a first tool-change member that is rotatably coupled to the base. The first tool-change member includes a first tool-engagement portion, geometrically complementary with a tool-change-engagement portion of a tool of a rotary drive.
摘要:
A hand-held rivet nut tool has a body having a base; two handles connected pivotally to the base; two pairs of links connected pivotally and respectively to the handles; a driven member connected pivotally to the pairs of the links; and a mandrel mounted rotatably through the driven member and the base. A push-and-pull mandrel-driving device or a rotational mandrel-driving device is mounted detachably and hence replaceably on the driven member, and is capable of driving the mandrel, the bushing and the threaded shaft. A user is allowed to choose either the push-and-pull mandrel-driving device or the rotational mandrel-driving device according to different working spaces or personal practices.
