Befestigungseinrichtung fuer scheibenfoermige Werkzeuge an der Werkzeugspindel einer tragbaren Elektrowerkzeugmaschine.

EP 253181 A UPAB: 19930923 A fixture for a grinding wheel to an electric angle grinder is based on a clamping flange by which the wheel is clamped to the abutment of the hollow spindle. This flange is screwed to the threaded pin of a clamping pin. The cavity between the surfaces is filled with a plastic matrial, e.g. PVC of a low degree of polymerisation which is poured in as a liq. when hot and becomes a jelly when cold. By applying the lever on the thrust disc, the plunger is moved to displace the jelly in one of the cavities for a firm connection between for the wheel clamped between. ADVANTAGE - This relieves the clamping flange only when the grinding disc is to be changed and is ideal for one-hand grinders.
