CA 2262570
A guiding frame has a carrier (10) provided with a fastening groove (11) and which carries a guiding rail (12) parallel to the carrier and secured in the fastening groove (11). A guiding bearing (13) that guides a sliding part (22) is supported on the guiding rail (12). In order to improve a guiding frame having the above-mentioned features in such a way that it can be used for highly accurate positioning tasks of even heavy loads, in particular tool and/or workpiece carriages, the substantially rectangular guiding rail rests with rounded supporting edges on the edges of the carrier which delimit the fastening groove (11) or on an intermediate bearing which bridges the fastening groove (11).
L'invention concerne un châssis de guidage comprenant un support (10) pourvu d'écrous de fixation (11), qui porte au moins un rail de guidage (12), parallèle à ce support, fixé à un des écrous de fixation (11), rail sur lequel repose un roulement de guidage (13) qui guide une partie chariot (22). Pour améliorer un bloc à colonnes présentant les caractéristiques susmentionnées de sorte qu'il convienne aux positionnements extrêmement précis même de charges lourdes, en particulier d'un chariot porte-outil et/ou porte-pièce, il est proposé selon l'invention, que le rail de guidage (12) sensiblement rectangulaire repose, par une partie bombée, sur les bords du support limitrophe de l'écrou de fixation (11) ou bien sur un palier intermédiaire chevauchant l'écrou de fixation (11).
