  • brushes inserted into the incisions of the inner cylinder are displaced radially outward by a part to be cleaned by the additional path length provided by means of the outer cylinder and therefore protrude more or less far into the interior of the inner cylinder in accordance with the rotational position of the outer cylinder .

Abstract

L'invention concerne un procédé et un dispositif pour le nettoyage de boulons de différents types et diamètres ou de filetages extérieurs de tels boulons. Au moins une brosse (3; 8) est montée élastiquement dans le dispositif de nettoyage, tout en étant déplaçable radialement par rapport à l'axe central (100) d'une cavité (20) du dispositif. Par déplacement d'un organe de réglage (2), les brosses (3; 8) sont réglées en position par rapport à l'axe central (100), sur le diamètre du boulon correspondant, de manière à libérer une ouverture, dans la cavité (20), pour l'introduction du boulon. Le boulon, qui est introduit par cette ouverture, vient en contact avec la ou les brosse(s) (3; 8) et se trouve nettoyé par le mouvement relatif entre le boulon et la ou les brosse(s) (3; 8). Sur la ou les brosse(s) (3; 8) agit un élément faisant ressort (5) réglable au moyen d'un organe de réglage (2) agissant sur cet élément faisant ressort (5). La ou les brosse(s) est(sont) constituée(s) par une pluralité de disques (8b, 8c, 8d, 8e) formant une pile (8), deux disques adjacents (8b, 8c, 8d, 8e) étant maintenus à distance par un élément d'écartement (8x). La ou les brosse(s) peu(ven)t être également constituée(s) par une barre (3) munie d'un support sur lequel sont fixés des faisceaux de poils, les bordures des poils formant des zones taillées obliquement.
