Abstract:
This invention relates to turret heads for machine tools, such for instance as vertical turret lathes, boring mills and the like, and it refers particularly to the revolving, indexing and locking mechanism for the head whereby it is rotated on its bearing and secured in desired positions. The object of the invention is to generally improve upon devices of this class and particularly to provide novel mechanism for rotating the head upon its saddle so as to bring the respective tools in position to be used; to provide improved means for insuring the proper indexing of the head when so adjusted, and to cause the proper locking of the head in such adjusted positions; to so construct the several parts as to prevent any back swing of the head and its tools when being adjusted; and finally to arrange the whole so as to insure ease of operation, accuracy and permanency of adjustment.
Claim:
The combination of a head supporting member bearing a stud, bevel faced pins mounted in said member, a head pivotally mounted upon the stud, adjustable pins carried by the head to register with and engage the pins of the supporting member and means for moving the head longitudinally upon the stud to engage and disengage the said pins. |
