Abstract
NC turret lathe comprising a tool turret rotatable about an indexing axis and mounted for rotation in a turret slide displaceable in a direction parallel to the indexing axis, also comprising a turret indexing drive monitored by a control mechanism for rotating the tool turret, and a slide drive monitored by a control mechanism for displacing the turret slide. In order to decrease the expenditure required to index the tool turret, the slide drive also constitutes the turret indexing drive, and the slide drive control also serves to monitor the turrent indexing drive. An actuatable coupling is provided between the slide drive and the turret to prevent undesired rotation of the turret when it is only to be slidably displaced.
Claims8
An NC turret lathe comprising a frame;
- a spindle rotatably mounted on said frame;
- means on said spindle for holding a workpiece;
- a slide slidably guided on said frame along a path of movement;
- a tool turret mounted on said slide for rotation about an indexing axis;
- drive means operatively connected to said slide;
- control means constantly coupled with said drive means for monitoring said drive means;
- first connecting means constantly interconnecting said drive means and said slide whereby said drive means moves said slide along said path of movement;
- second connecting means interconnecting said drive means and said turret whereby said turret is rotated about said indexing axis by said drive means;
- said second connecting means including a drive coupling movable between engaged and disengaged positions whereby said drive means is operatively connected to rotate said turret only when said drive coupling is in its engaged position;
- said drive means remaining in operative connection with said first connecting means and slide regardless of the position of said drive coupling.
