Definitions

  • the invention relates to a two-spindle lathe whose parallel work spindles are each assigned a cross slide carrying a longitudinal slide and can be displaced on a common transverse guide by a separate drive at the adjacent end of the transverse guide via a drive spindle.
  • Lathes of this type are known both with vertical and horizontally arranged horizontal spindles, the cross slides being horizontally movable in both cases * .
  • several tools can be arranged on the longitudinal slides which can be displaced thereon, each of which is brought into the working position one after the other, for example with the aid of tool turrets.
  • the invention is therefore based on the object of further developing a twin-spindle lathe of the type mentioned at the outset in such a way that idle times can be largely avoided and the total working times can be reduced.
  • this object is achieved in that a third, two working spindle is arranged in a common cross slide on the cross guide, which likewise carries a longitudinal slide and can be moved by a separate drive at any end of the cross guide, via a further drive spindle .
  • FIG. 1 shows a largely schematic representation of the front view of a two-spindle vertical turning machine with three cross slides, on each of which a longitudinal slide is arranged
  • Fig. 2 shows a cross section through the Füh ⁇ tion of the 'cross slide according to line II-II th with the right and Querschlit ⁇
  • Fig. 3 shows a similar cross section
  • the bed of a two-spindle vertical automatic lathe is shown with 1o, which contains the headstock (not shown) for two work spindles with chucks 12a and 12b in a front, lower part 1oa.
  • a guide bar 14 is attached to the rear part 10b of the bed 10, which is provided with two outer guide rails 16, 18 right cross slide 2oa, 2ob and an intermediate cross slide 2oc located between them.
  • Each cross slide 2oa, 2ob, 2oc in turn carries guides 22a, 22b, 22c, each for a vertically displaceable longitudinal slide 24a, - 24b, 24c, which is equipped with a tool turret 2 ⁇ a or 26b or 26c for holding a wide variety of tools.
  • the guide bar .14 contains, as can be seen from FIG. 2, on the side facing the cross slide between the guide strips 16, 18 one above the other two channel-shaped channels 28, 3o which are open towards the cross slide.
  • the two outer cross slides 2oa, 2ob each engage with a spindle nut 32 attached to the lower channel 28 and are gripped there by one of two coaxial drive spindles 34a and 34b, respectively - by drives 36a and 36b at the adjacent end of the guide bar 14 can be driven.
  • Each drive spindle 34a, 34b thus has a length which is less than the length of the guide beam 14 and " limits the path of the associated cross slide 2oa or 2ob to the area of the associated work spindle 12a or 12b.
  • the middle cross slide 2oc carries a spindle nut 32c, which engages in the lower part of the spindle nuts 32a and 32b but in the upper channel-shaped channel 3o and is gripped there by a drive spindle 34c.
  • the drive spindle 34c extends from a drive 36c at the right end of the guide beam 14, for example, above the drive 36b far beyond the center of the guide beam 14 and thereby allows the cross section 2oc to be shifted in the region of both work spindles 12a and 12b.
  • at least the associated tool turret 36c is designed such that the tools attached to it can machine the workpieces on one or the other work spindle in two diametrically opposite positions.
  • the aridity spindles 34a, 34b, 34c as well as the drive spindles (not shown) in the longitudinal slides are preferably ball screws, whereby a particularly precise adjustment of the slides can be achieved.
