ABSTRACT:
Equipment and method for automatically changing tools on hobbing machines. The machines are of the type equipped with a bedplate to which are connected a pair of uprights, the first of which for supporting a work head and the second of which for supporting a cutter head. The cutter head is rotatable around a horizontal axis and supports horizontally a hob at the extremities thereof. The equipment includes guide means provided in the cutter head, parallel to the axis of the hob, and a support for at least one extremity of the hob is slidable inside the cutter head along the guide means. The support is also displaceable, without being withdrawn from the cutter head, by an amount sufficient to free the two extremities of the hob from the cutter head. The equipment includes also an independent frame fixable to either one of the pair of uprights, and supporting grasping means located above the cutter head. A tool storage space which is also supported by this frame is constituted by a head formed of a number of pairs of arms between which the extremities of the hob could be engaged.
