Abstract
Improvements in thread-cutting devices for a center lathe, comprising a base mountable on the tool holder, a slider mounted to slide on the base parallel to the main axis of the lathe, a control mechanism that derives its movement from the driving screw of the lathe and it is operable to produce the reciprocating movement of the slide along the base, a first element of elastic influence operable to request the slide in engagement with said control mechanism, a tool holder slidably mounted on said slide to move transversely to the axis main of the lathe, a control bar mounted for the axial displacement of said slider to cyclically effect the aforementioned transverse movement of said tool holder to perform the tool at the end of each fillet cutting pass and re-play the tool at the end of a movement return a second influential member the operative rod for requesting one end of said bar in engagement with means for cyclically requesting said control bar axially in a first direction thereof, an inclined plane coupling between the other end of the bar and said tool holder, whose coupling transmits the axial movement of said bar as a transverse movement to said tool holder, and a stirrup stop organization provided with a plurality of stirrup faces that limit the movement of said tool holder towards a workpiece surface, whereby controls the depth of cut of the tool on the workpiece being machined, characterized in that the inclined plane coupling between said control bar (17) and the tool holder (14) comprises a sliding block (27) consisting of one end (26) of said bar (17) and engaged in a groove (28) of one for an insert element (29) that is attachable to the tool holder s in a position selected from two positions, in whose positions said slot (28) is arranged angularly at different inclinations with respect to the main axis (XX) of the lathe, and because the stirrup stop arrangement comprises two sets of stop stops stirrup (41, 42) to limit the depth of cut of the tool, said tool holder (14), or an element mounted on it being pawnable, with one or the other set of stops depending on the position available, between the two existing ones, said insert element (29) of said tool holder (14).
