(54) Device for quick removal of a tool support


(57) A device for rapidly removing a tool support, particularly but not exclusively useful during reconditioning of grinding wheels of grinding machines, the support including a body which is partially accommodated in a seat for receiving it; its particularity consists of the fact that it includes at least one internally threaded member which is suitable to engage a portion of the body which is externally threaded complementarily so as to abut against the rims of the seat, causing the disengagement of the body from the receiving seat. The invention fully solves the problems observed in the prior art, since it allows to remove the support from the machining head rapidly and easily. The device is also suited for fitting the support on the head without the risk of damaging the dressing tool.
