Detailed description

Figure 1

Modular adapter (0), according to (0) (figs. 1, 4, 9, 10, 11, 12, 12), with an exterior of ergonomic non-slip hard rubber lining on a hexagonal steel body, very long-lasting since it lacks wear and breakdown due to its simplicity, the interior of which is compartmentalized with a hexagonal hole with a socket wrench function to house the axial displacement nut of two power screws; module (1) or module (2) and a cylindrical hole to house their respective axial bearings, while at the front end it has a left-hand internal thread, where the accessory components are installed, (3), (4), (5 ), (6) and (7).

Module (1) for rivets, according to (figs. 1 and 13) consisting of a perfected power screw from the shaft (13) to the jaws (39), whose nut (38) has axial movement within the internal hexagon of the adapter (0) ( figs. 1 and 13), which also acts as a jaw holder, can come and go from both ends of the spindle, always being retained by two springs and without fixed stops.

Module (2) for threads, according to (figs. 1, 9 and 11) consisting of a perfected power screw from the axis (13) to the left-hand thread nut (12) welded to the axial movement nut (20), then having been mounted on the spindle (21) and caged in it with a castellated nut (19) fixed to the spindle with a transverse pin, so that from the inside of the axial movement nut (12) the screwdriver can access the slot (18) of the screw (17) to move the steel ball (16) in order to modify the axial travel (15) to activate the “torque” of the drill and cut off the power supply of the device, to avoid damage to the fixing threads.

Jaw guide (3) according to (figs. 1 and 13) with left-hand thread (40) to screw into (14) (fig.

13), which closes the front end of the adapter (0) while aligning the jaws (39) of the jaw holder (38) towards the inner end of the rivet nozzle (4) threaded at its tip.

Rivet nozzle (4) selector according to (figs. 1 and 13) for the different diameters of tubular rivets.

Perforated base of nuts and bolts (5) according to (figs. 1, 9 and 11) with left-hand thread (14), which closes the front end of the adapter (0) (fig. 1) to serve as support;

• According to (fig. 9) of the wing (27) of the insertable nuts (25), so that the externally threaded nut driver (6), threaded left-hand in the module handle holder (2), comes out through its front hole to screw them in according to the usage procedure (fig. 5).

• According to (fig. 11) of the wing (33) of the insertable nuts of the insertable bolts, since an insertable bolt is actually a screw whose head is an insertable nut, which is the one that is riveted by pulling its screw, which is the one that is inserted through the front hole of the perforated base (5), so in this case the bolt puller (7) that screws into the screw according to the use procedure in (fig. 5) does so from inside the riveter into its front female thread.

Externally threaded nut strippers (6) according to (figs. 1, 9 and 10) consisting of a cylindrical rod with a front thread appropriate for the thread of the insertable nut that is intended to be riveted and that comes out through the front hole of the perforated base of nuts and bolts (5), while its left-hand rear thread (12) (figs. 9 and 10) is mounted on the left-hand female thread (12) of the handle holder.

Bolt puller with female internal thread (7) according to (figs. 1, 11 and 12) consisting of a cylindrical rod with its front female thread appropriate for the thread of the screw of the bolt to be riveted and which always remains inside the perforated base (5), while its left-hand rear thread (12) (figs. 11 and 12) is mounted on the left-hand female thread (12) of the handle holder, since in this case it is the thread of the bolt that is inserted through the hole in the perforated base (5) to be screwed from inside the riveter, since the insertable bolt according to (fig. 11) is actually a screw (34) with an insertable nut head (31), which inserts the screw through the hole in the perforated base of nuts (5) inside which the internal female thread bolt puller (7) awaits to screw it in, pull it and generate the riveting of the nut in its head.
