Title (EN) ADJUSTABLE MACHINE TOOL GUARD
(FR) DISPOSITIF DE PROTECTION REGLABLE POUR MACHINE-OUTIL
Abstract: front page image
(EN)An adjustable guard for splintering machine tools, preferably for lathes and circular grinders, the said guard comprising a transparent shield (6) and moving along guide bars (1) parallel to the lathe spindle. The object of the invention is to achieve a machine tool guard which, compared with previous art guards, is easily adjusted, modified and suited for various purposes. The guard according to the invention comprises at least one guide bar (1) formed of a girder or equivalent, preferably located over the machine tool, on which bar rests a carriage moving along the guide bar (1), the said carriage (4) being attached to the guide bar (1) with rolling bearings, preferably rollers (9), so that owing to the form of the guide bar (1) and the weight of the carriage (4) the guard device is not derailed from the guide bar. The carriage (4) is provided with guides or equivalent, and the shield (6) as well as the body (5) rest on the carriage and can be moved along it roughly horizontally, in a transversal direction with respect to the guide bar (1) and the spindle. Moreover, the distance of the guide bars (1) from the piece to be machined can be adjusted by employing the rails (2) and the support bases (3). The shield (6) is attached to the body (5) with hinges located at the top edge of the shield. The body (5) can be provided with a working light and aspirator connection (8).
(FR)Dispositif de protection reglable pour machine-outil susceptible de projeter des eclats, de preference pour tour et machine rectifieuse circulaire, ledit dispositif de protection comprenant un ecran transparent (6) se deplacant le long de barres de guidage paralleles a l"arbre de tour. Le but de l"invention est d"obtenir un dispositif de protection pour machine-outil qui, compare aux dispositifs de protection de l"art anterieur, peut etre regle ou modifie facilement, et se prete a plusieurs taches. Le dispositif de protection decrit comprend au moins une barre de guidage (1) formee par un support ou equivalent, situe de preference sur la machine-outil; sur la barre repose un chariot se deplacant le long de la barre de guidage (1), ledit chariot (4) etant fixe a la barre de guidage (1) au moyen de palices de roulement, de preference de rouleaux palices (9), de telle maniere que, grace a la forme de la barre de guidage (1) et au poids du chariot, (4) le dispositif de protection ne deraille pas de la barre de guidage. Le chariot (4) est pourvu de guides ou equivalents, et l"ecran (6) ainsi que le corps (5) reposent sur le chariot et peut etre deplace le long de celui-ci horizontalement, dans une direction transversale par rapport a la barre de guidage (1) et a l"arbre de tour. En outre, la distance entre la barre de guidage (1) et la piece a usiner, peut etre ajustee en utilisant les rails (2) et les bases de support (3). L"ecran (6) est fixe au corps (5) par des charnieres situees sur le bord superieur de l"ecran. Le corps (5) peut etre pourvu d"un eclairage de travail et d"une connexion d"aspiration (8).
