Definitions

  • the invention relates to a machine tool with a machine housing and a three-dimensionally movable processing unit.
  • Such machine tools are known from practice to be able to quickly process large numbers of workpieces. Since machining the workpiece with just one tool is generally not sufficient, it is also known to use tool changing systems in which the tool held in the work spindle of the machine tool is replaced by another tool.
  • the grippers which are widely used in practice, can be mentioned as examples of such a tool changing system.
  • the known tool changing systems require a relatively large amount of time to carry out the tool change, which is particularly the case with a large number of different tools required adversely affects the production process, the time required and the resulting costs.
  • the invention is therefore based on the object of designing a machine tool of the type mentioned at the outset in such a way that the change between different machining steps of the workpiece can be carried out more quickly.
  • machining unit is assigned a spindle carrier with a plurality of work spindles each having a tool holder that the
  • Work spindles are arranged parallel to each other, and that each of the work spindles is adjustably mounted in the spindle carrier in the longitudinal direction of its spindle axis.
  • This design has the advantage that very quickly, in less than 1 second, in particular in only 0.5 seconds, the axial adjustment of the work spindles allows different tools to be detached in the working position in a short way.
  • the associated increase in productivity can be demonstrated using a comparative calculation.
  • the tool change in a machine tool with a turret head with 6 tools typically takes about 3.4 seconds for the swiveling process of the turret head with the braking of 10,000 revolutions per minute to a standstill, moving the tool out of the interference contour, moving the drive shaft into the swivel position, swiveling into the next turret position, moving the drive shaft into the drive position, accelerating from standstill to 10,000 revolutions per minute with moving into the machining position.
  • a tool change in the invention takes only 0.9 seconds for the retraction of the one work spindle and the new positioning of the three-dimensionally movable processing unit for the use of the other work spindle and its advancement into the work position.
  • the 6-fold tool change in the turret head therefore takes a total of 20.4 seconds, so that only 9.6 seconds are available as machining time.
  • the entire changing of the tools takes only 5.4 seconds. So there is an additional processing time of 15 seconds, or half of the bar.
  • a spindle drive is assigned to the work spindle, since such a simultaneous, opposite adjustment of the work spindles can be carried out in a simple manner.
  • the spindle drives are held on the spindle carrier in order to achieve a compact design.
  • the work spindles are coupled to a spindle drive via a transfer case. It is preferred if the transfer case and the spindle drive are held on the spindle carrier.
  • the work spindles are arranged in the spindle carrier on the grid positions of a cross grid and if there are four work spindles, i.e. the number of tools is also limited to a customary minimum.
  • the machine tool can be used in a single station, or in a linked arrangement, in the longitudinal or circular transfer area.
  • a stop for fixing the axial position of the work spindle in the working position is provided in the spindle receptacles and a cone is formed in each case with side walls inclined towards the free end of the work spindles for cooperation in the
  • a cooling medium supplied via coolant connections is provided for cooling the tool and / or workpiece and / or for lubrication, the spindle carrier, the pressure medium connections and the spindle drive being arranged axially staggered in a structurally simple arrangement.
  • a more compact design with a significantly reduced space requirement can be achieved if the coolant connections are integrated in the spindle carrier.
  • Fig. 1 is a perspective view of the isolated processing unit with a first one
  • FIG. 2 shows a representation corresponding to FIG. 1 with a work spindle different from FIG. 1 in the working position
