Part (a) of the gear assembly (4) is mounted on the hexagonal axis (26) integral with the cylinder (7a) while part (b) is mounted on the same axis (26) but can turn and slide freely. Said part (b) of the gears (4) is compressed by the spring (22) against the part (a) to form a variable and adjustable force transmission by the set of two opposite sockets (β).
Selon un détail d'invention la partie(a) de l'ensemble(6 ) est montée coulissante sur l'axe(25) et munis des cames(19) du côté opposé de la tête (T), alors que la douille(6b), par son côté rétréci est prisonnière du carter(20) du boîtier(1) et solidaire de la molette gradué(16) servant au réglage de la pression du ressort(22) sur l'engrenage(4b) . Les axes(25)et(26) selon l'invention sont alésés axialement pour y faire coulisser la vis médiane(9) et contient le ressort(5b) lequel collabore avec le ressort(5a) et la douille borgne(17) pour y repousser la vis médiane (9) dans la position initiale . La douille borgne(17) est munie d'un épaulement (21).According to a detail of the invention, the part (a) of the assembly (6) is slidably mounted on the axis (25) and provided with cams (19) on the opposite side of the head (T), while the sleeve ( 6b), by its narrowed side is trapped in the housing (20) of the housing (1) and secured to the graduated wheel (16) used for adjusting the pressure of the spring (22) on the gear (4b). The axes (25) and (26) according to the invention are axially bored to slide the middle screw (9) therein and contains the spring (5b) which collaborates with the spring (5a) and the blind sleeve (17) to push the middle screw (9) back to the initial position. The blind sleeve (17) is provided with a shoulder (21).
Le ressort (5a) et monté sur la douille borgne (17) se trouve captif entre les épaulements (21) de la douille (6b) et l'épaulement(18 ) de la douille borgne (17).The spring (5a) and mounted on the blind sleeve (17) is captive between the shoulders (21) of the sleeve (6b) and the shoulder (18) of the blind sleeve (17).
Ledit ressort(5a) est d'une force légèrement supérieure a la force du ressort(5b),et se trouve comprimer, pour continuer l'action de la vis médiane(9) après la limite du carter(20) . Ce dépassement de la langueur de l'outil par la vis médiane(9) provoque l'ouverture de la trappe(14), et engage le nouveau rivet ou la nouvelle vis auto-perçante dans le canal axial(33) du corps mobile(8). La vis médiane(9) est montée coulissante , mais elle est bloquée par la bille(44)avec sa gorge(45) dans le sens de la rotation , par rapport au corps mobile(8). Ladite vis(9 )est entraînée en rotation par l'ensemble(7) et transmet le mouvement au corps(8)lequel est terminé par la tête (T). Dans la tête (T) se trouve bloquer le rivet (12) et est entraîné on rotation pour effectuer le percement des pièces à assembler .Said spring (5a) has a force slightly greater than the force of the spring (5b), and is compressed, to continue the action of the central screw (9) after the limit of the casing (20). This overshoot of the languor of the tool by the central screw (9) causes the hatch (14) to open, and engages the new rivet or the new self-piercing screw in the axial channel (33) of the movable body ( 8). The central screw (9) is slidably mounted, but it is blocked by the ball (44) with its groove (45) in the direction of rotation, relative to the movable body (8). Said screw (9) is rotated by the assembly (7) and transmits the movement to the body (8) which is terminated by the head (T). In the head (T) is blocked the rivet (12) and is rotated to perform the drilling of the parts to be assembled.
Une fois le percement terminé, le rivet c'engage dans le trou de la pièce, à assembler c'qui fait porter la douille à crémaillère(28) à l'endroit du rivetages. La douille(28) coulissent sur le corps(8) contre le ressort(24) est accroché par les molettes(27) en dégageaient les billes (23) et les mâchoires(IO), lesquelles laissent passer les rivets à l'extérieur de la tête (T), et la plaque contre l'objet à assembler.Once the drilling is finished, the rivet engages in the hole of the part, to assemble what brings the rack sleeve (28) to the location of the rivets. The sleeve (28) slides on the body (8) against the spring (24) is hooked by the knobs (27) released the balls (23) and the jaws (IO), which allow the rivets to pass outside of the head (T), and the plate against the object to be assembled.
La douille(28) sous la pression du ressort(24) referme les mâchoires(IO) derrière la tête du rivet(12) en se placent dans la position de tirage de la tige du rivet afin d'effectuer son épanouissement du coté borgne du trou pratiqué dans l'objet .The sleeve (28) under the pressure of the spring (24) closes the jaws (IO) behind the head of the rivet (12) and is placed in the pulling position of the rod of the rivet in order to carry out its development on the blind side of the hole in the object.
La vis médiane étant coulissée du côté de la tête (T), la bille(42) tombe en face et c'installe dans le pas de vis de la vis médiane(9). Ladite bille(42) est entraîné en rotation forcée par la came (7a) du cylindre(7), ce qu'il provoque le coulissement de la vis médiane (9) dans la direction du carter(20) , en comprimant le ressort(5a) tirant la tige du rivet (12), afin de pratiquer le rivetages. Poursuivant son mouvement la vis médiane(9) continue à comprimer le ressort(5b), puis en poussant la douille borgne(17) à comprimer le ressort (5a). Dans sa course en arrière la vis médiane(9) rencontre le coulisseau(43) en le repoussant ver l'extérieur du corps mobile (8). Lorsque la parti (11) du pas de vis, laquelle selon l'invention est plus profonde que le reste , atteint la bille(7a) et le fait passer de l'autre côté de la came(42)du cylindre (7), ce qui libère la vis médiane(9) de la force exercée par le moteur électrique (2).The middle screw being slid from the side of the head (T), the ball (42) falls opposite and this is installed in the thread of the middle screw (9). Said ball (42) is driven into forced rotation by the cam (7a) of the cylinder (7), which causes the sliding of the central screw (9) in the direction of the housing (20), compressing the spring ( 5a) pulling the rod of the rivet (12), in order to practice the riveting. Continuing its movement, the central screw (9) continues to compress the spring (5b), then pushing the blind sleeve (17) to compress the spring (5a). In its backward movement, the central screw (9) meets the slide (43) by pushing it towards the outside of the movable body (8). When the part (11) of the screw thread, which according to the invention is deeper than the rest, reaches the ball (7a) and causes it to pass on the other side of the cam (42) of the cylinder (7), which releases the middle screw (9) from the force exerted by the electric motor (2).
Etant libérée, la vis médiane (9) est repoussée par le ressort (5a) et( 5b) dans le sens inverse .Sur son chemin de retour la vis médiane (9) rencontre le rivet ou la vis auto-perçante engagée dans le canal (33), par le distributeur (13) et le repousse dans son logement des mâchoires(IO) en y rétablissent tous les composantes de la tête(T), dans la position initiale de perçage. La vis médiane(9) dans son élan en direction de la tête(T) rencontre le nouveau rivet , lequel s'enfonce par sa tige dans le dispositif de tirage(31 ) et chasse la tige cassée dans le canal d'évacuation(15). Les rivets ou les vis autos perçantes sont fournies par le chargeur ) lequel est équipé d'une trappe(14) commandée par la vis médiane(9)en collaborant avec le coulisseau(43) et d'un système d'avancement de rivets ou de vis commandés par l'ouverture de la trappe(14).Being released, the middle screw (9) is pushed back by the spring (5a) and (5b) in the opposite direction. On its return path, the middle screw (9) meets the rivet or the self-piercing screw engaged in the channel (33), by the distributor (13) and pushes it back into its jaw housing (IO) by restoring there all the components of the head (T), in the initial drilling position. The middle screw (9) in its momentum towards the head (T) meets the new rivet, which is inserted by its rod into the pulling device (31) and drives the broken rod into the evacuation channel (15 ). Rivets or self-drilling screws are supplied by the charger ) which is equipped with a hatch (14) controlled by the central screw (9) collaborating with the slide (43) and with a advancement system of rivets or screws controlled by the opening of the hatch (14 ).
