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). |
