Title
(EN) SLIDE ARM OF WORKING MACHINE
(FR) BRAS COULISSANT DE MACHINE A TRAVAILLER
Abstract
(EN)
A slide arm of a working machine capable of being smoothly operated by simplifying a structure and increasing an assembly accuracy, wherein a tubular structural body (outer tube, inner tube) formed in a generally triangle in cross section and in an arc shape at each apex part of the cross section by bending one sheet of plate is combined with a nest through a sliding member (slide bearing unit and slide block piece) installed at each apex part, and a slide mechanism is provided to slide the tubular structural body.
(FR)
L'invention concerne un bras coulissant d'une machine à travailler que l'on peut manoeuvrer en douceur en simplifiant une structure et en augmentant la précision d'un ensemble. Un corps structural tubulaire (tube externe, tube interne), en forme généralement triangulaire en coupe transversale et arciforme à chaque partie sommet de la coupe transversale par pliage d'une plaque, est combiné avec un logement par le biais d'un élément coulissant (unité d'appui coulissante et pièce bloc coulissante) placé à chaque partie sommet. Enfin, l'invention concerne un mécanisme coulissant qui permet de faire coulisser le corps structural tubulaire.
