Abstract
In machine tools such as boring machines, milling machines, milling-boring machines and similar, cutterheads and/or workheads are used having one or more orientation axes so that the tool, or workpiece, can take on the greatest number of positions possible to satisfy the various working requirements. The system to block and position the movable pieces is of particular importance since it must give precision and rigidity to the system. At present, these heads can be divided into three categories: A)- with independent motorization of the axes and continual positioning with blockage through friction, B)- heads which use the movement of the mandrel for angular movements plus blocking and unblocking of the various axes with frontal teeth and positioning with tooth pitch, very precise but forced to a minimum movement of a tooth pitch and its multiples, C)- heads like those in category B) but with precision measurement systems on the axes and blockage through friction, with continual positioning without reference teeth and, therefore, with an inferior level of precision than category C).The aim of the device subject of the present invention is to obtain a continual positioning head having the precision and safety of those using frontal teeth.
