VORRICHTUNG ZUM ELEKTROFUNKEN-AUFTRAGSCHWEISSEN AUF DIE STIRNFLAECHE VON ROTATIONSKOERPERN

摘要

A machine for electric spark deposit welding of rotational surfaces comprises a DC electric motor (1) connected by a drive screw (3) with a deposit welding head (5), which welding head is mounted directly on a nut (4) in engagement with the screw (2) and comprises three disc electrodes (8) set at an angle of 120 DEG to each other and each mounted on an arm hingedly connected to the deposit welding head (5), each disc electrode (8) having an associated electric motor (9), there being disposed below the deposit welding head (5) a horizontal self-aligning support (11) fastened to a shaft (12) connected in turn via a flexible link (13, 14) to an oscillating system (15), said shaft additionally being connected to means (16) for imparting rotational motion thereto. <IMAGE>
