Title
(EN) POWER TOOL
(FR) OUTIL COMMANDE PAR MOTEUR
Abstract
(EN)
A grinding tool has a mains or battery powered motor (40) within its casing (16), the casing being snap-fitted to a base (14), the motor driving a rotatable shaft (39) carrying a grinding wheel (20; 102; 157) or a spur gear (184), and the casing being provided with undercut grooves (24), slidingly to engage respective different adapters (11; 12; 13; 101; 145; 180) having complementary projections (25), as well as a catch (17) to engage respective openings (60; 83; 84; 98) in front faces of the adapters, thereby to retain each adapter at a work station of the tool against longitudinal and lateral movement. The adapters (11; 12; 13; 101; 145) provide a location which, when the adapter is fitted at the work station, is disposed relative to the grinding wheel so that, in use, there is correct positioning between part of an implement at said location and said grinding wheel for said part to be worked by the wheel. One of the adapters (180) is used with the spur gear (184) instead of a grinding wheel on the shaft (39) to transmit the motor drive to a flexible drive releasably engageable with the adapter.
(FR)
Un outil de meulage comprend à l'intérieur de son enveloppe (16), un moteur (40) alimenté par secteur ou par batterie, l'enveloppe s'enclenchant sur une base (14). Le moteur entraîne un arbre rotatif (39) portant une meule (20, 102, 157) ou un engrenage droit (184). L'enveloppe est pourvue de rainures à paroi en biais (24) afin d'entrer en contact coulissant avec des adaptateurs respectifs différents (11, 12, 13, 101, 145, 180) comprenant des éléments en saillie complémentaires (25), ainsi que d'un élément de retenue (17) entrant en contact avec des ouvertures respectives (60, 83, 84, 98) ménagées dans les faces avant des adaptateurs afin de maintenir chaque adaptateur à un poste d'usinage de l'outil et de prévenir tout déplacement longitudinal et latéral. Lorsqu'ils sont fixés au poste d'usinage, les adaptateurs (11, 12, 13, 101, 145) présentent un point de montage dont la disposition, par rapport à la meule, permet, en cours d'utilisation, un positionnement correct entre une pièce d'un outil monté au niveau de ce point et la meule, afin que cette pièce puisse être usinée par la meule. L'un des adaptateurs (18) est utilisé avec l'engrenage droit (184) au lieu de la meule sur l'arbre (39), afin de transmettre l'entraînement du moteur à un dispositif d'entraînement souple entrant en contact libérale avec l'adaptateur.
