Abstract
A machining head presenting a hollow body in turn presenting a first crosspiece with a seat for supporting in sliding manner a motor-driven tool spindle. The body also presents a second crosspiece fitted with means for axially displacing the spindle which may be of different lengths and is driven by an electric motor via a screw-nut screw pair located between the second crosspiece and a third crosspiece connected removably to the spindle. The second crosspiece presents an end portion pivoting by means of a pin on an appendix of the hollow body, and is fitted to the body by means of a pair of locating pins and a pair of screws. By disconnecting the third crosspiece from the spindle and rotating the second crosspiece about the pin, the spindle may be changed without removing the machining head from the machine. The locating pins are removed from their respective seats by means of a key in the form of a screw and normally housed in a seat on the crosspiece.
