Definitions

  • the invention relates to a machine tool and a method for operating the machine tool.
  • EP2522457A1 discloses a machine tool with a machine frame and a first work spindle, which is rotatably mounted about a first spindle axis, and a workpiece clamping device designed to hold at least one first workpiece.
  • the workpiece clamping device comprises a first workpiece table.
  • the machine tool known from EP2522457A1 has the disadvantage that its flexibility for machining the workpieces is insufficient.
  • the object of the present invention was to overcome the disadvantages of the prior art and to provide an improved machine tool.
  • a machine tool is designed.
  • the machine tool comprises:
  • the machine tool according to the invention offers the advantage that the flexibility of the machine tool can be increased by arranging the first rotary table on the first workpiece table. This allows for an increase in the complexity of the workpieces that can be machined. Furthermore, it can be advantageous for the first spindle axis to be aligned parallel to a horizontal Z-axis, with the first work spindle being displaceable along the Z-axis by means of a first Z-axis adjustment unit, along a vertically aligned Y-axis by means of a first height adjustment unit, and along the X-axis by means of a first X-axis adjustment unit. This measure can further increase the flexibility of the machine tool. Moreover, this measure can achieve good machining results when machining workpieces.
  • a partition wall is formed on the first rotary table, wherein a first workpiece holder for receiving a first workpiece is formed on a first side of the partition wall, and a first rear workpiece holder for receiving a first rear workpiece is formed on a second side of the partition wall.
  • the first workpiece holder In a first pivot position of the first rotary table with respect to the first rotary table pivot axis, the first workpiece holder is assigned to the first work spindle, and the first rear workpiece holder is accessible for loading the first rear workpiece.
  • the first rear workpiece holder In a second pivot position of the first rotary table with respect to the first rotary table pivot axis, the first rear workpiece holder is assigned to the first work spindle, and the first workpiece holder is accessible for loading a first workpiece.
  • the rotary table's swivel axis allows for easy rotation of the first side into the work area and the second side into a loading area, or vice versa. This enables time-saving machining and loading, especially for large workpieces. Furthermore, the swivel axis eliminates the need to invert the workpiece between loading and machining, thus preserving its orientation.
  • the machine control can be programmed such that the first rear workpiece is loaded at the first rear workpiece holder when machining the first workpiece held at the first workpiece holder does not require any pivoting of the first rotary table. This has the advantage that the first rear workpiece holder remains stationary during loading, allowing the first rear workpiece to be easily inserted into the first rear workpiece holder.
  • the load transfer of the first rear workpiece from a workpiece loading device to the first rear workpiece holder can be scheduled to occur when the first working spindle is not engaged with the first workpiece, or when the first working spindle is not performing end-surface machining on the first workpiece, but rather machining a surface that will be machined again in a subsequent operation. This measure prevents surface defects that could arise from the slight displacement of the first workpiece during loading of the first rear workpiece.
  • the weight force of the first rear workpiece is taken into account or compensated on the first rotary table.
  • Another advantageous configuration involves driving the first rotary table with a first drive motor and a second drive motor.
  • the first drive motor is coupled to the first rotary table via a first gearbox
  • the second drive motor is coupled to the first rotary table via a second gearbox.
  • the first drive motor and the second drive motor are pre-tensioned relative to each other, thus compensating for any backlash between the first and second gearboxes.
  • This offers the advantage that, through this This measure can improve the positioning accuracy of the first rotary table.
  • the preload between the first and second drive motors can be achieved by having them rotate at slightly different angular offsets. This causes one of the drive motors to, for example, lead the other and, via the coupling through the first rotary table, push against the second drive motor. This eliminates all backlash in the gears. Furthermore, this measure improves the positioning accuracy of the first rotary table.
  • first gearbox comprises a first pinion located on the first drive motor and engaging with the gear ring
  • second gearbox comprises a second pinion located on the second drive motor and engaging with the gear ring.
  • the first and second motor axes can be arranged at an angle to the first workpiece table swivel axis.
  • the first and second drive motors can be arranged in a V-shape within the first workpiece table.
  • the angle between the first and second motor axes and the first workpiece table swivel axis can be the same in absolute terms, but oriented in opposite directions.
  • the first drive motor can have a first motor shaft rotatably mounted about a first motor axis
  • the second drive motor has a second motor shaft rotatably mounted about a second motor axis, with the first and second motor axes aligned parallel to the first rotary table pivot axis.
  • This design offers the advantage that the gear ring, first pinion, and second pinion can be designed as spur gears, resulting in a simpler construction. This can lead to a surprising increase in positioning accuracy.
  • the gear ring, first pinion, and second pinion can be designed with helical teeth. This measure can achieve a surprising increase in positioning accuracy.
  • first and second drive motors opposite each other on the first rotary table, particularly opposite each other about a plane perpendicular to the first pivot axis.
  • first and second pinions can each be designed as bevel gears.
  • the pallet holder of the first rotary table can be coupled to a ring gear.
  • the first and second pinions, designed as bevel gears, can form a good torque-transmitting connection with the ring gear.
  • first motor axis and the second motor axis are arranged coaxially to each other, in particular that the first motor axis and the second motor axis intersect the first rotary table swivel axis. This has the advantage that the positioning accuracy of the first rotary table can be improved by this measure.
  • first motor axis and the second motor axis can be arranged offset from the first rotary table swivel axis.
  • first motor axis and the second motor axis are located in the They are arranged at the same distance offset from the first rotary table pivot axis. This has the advantage that the pinions of the first motor and the second motor can be identical parts.
  • the first drive motor and the second drive motor are mounted below the first rotary table in the first workpiece table, with the first workpiece table, viewed in cross-section, having a shape that tapers downwards from the first rotary table, at least in the area below it.
  • This has the advantage that the moment of inertia of the first workpiece table can be kept as low as possible.
  • this measure allows the working circle of the first workpiece table to be kept as small as possible.
  • the stability of the first workpiece table can be sufficiently high.
  • a tapered shape can be achieved by ensuring that the width of the first workpiece table, viewed in cross-section, is greater in the area of the first rotary table than the width of the first workpiece table on the underside facing away from the first rotary table.
  • the tapered shape can be formed by the side walls of the first workpiece table being V-shaped relative to each other.
  • the tapered shape can be achieved by a stepped design of the side walls of the first workpiece table.
  • a different tapered shape of the first workpiece table is possible.
  • the first workpiece table may be designed in the form of a box girder comprising a top plate, a base plate, a front web, and a rear web.
  • the mounting flange may be coupled to the top plate, particularly by bolting. All underlying components, such as the first drive motor and the second drive motor, may be arranged within the box girder structure of the first workpiece table.
  • the front web and the rear web may be tapered from the top plate to the base plate.
  • the front web and the rear web may be arranged in a V-shape.
  • a second working spindle can be arranged on the machine frame, which rotates around a second spindle axis.
  • the workpiece clamping device is rotatably mounted, comprising a second workpiece table, the second workpiece table being pivotably mounted about a second workpiece table swivel axis aligned parallel to a horizontal X-axis, and a second rotary table being arranged on the second workpiece table, which is pivotably mounted about a second rotary table swivel axis on the second workpiece table, the first work spindle and the second work spindle being spaced apart from each other along the X-axis, and the first and second workpiece tables being spaced apart from each other along the X-axis.
  • This has the advantage of improving the efficiency of the machine tool.
  • the second work spindle far enough along the horizontal X-axis to allow machining of the first workpiece mounted on the first rotary table.
  • This offers the advantage that the first workpiece mounted on the first rotary table can be machined with both the first and second work spindles.
  • the first workpiece mounted on the first rotary table can be machined simultaneously using both the first and second work spindles. This can be useful, for example, when the cutting forces need to be balanced. Simultaneous machining with the first and second work spindles can also be advantageous when the second workpiece mounted on the second rotary table is being changed at the same time. This further minimizes the machine tool's idle time and thus improves its efficiency.
  • first working spindle is arranged on a first spindle adjustment device and the second working spindle is arranged on a second spindle adjustment device, the second spindle adjustment device being a mirror image of the first spindle adjustment device.
  • This has the advantage that, through this The measure allows the first spindle adjustment device and the second spindle adjustment device to be positioned relative to each other in such a way that the distance between the first working spindle and the second working spindle is as small as possible. This facilitates the machining of a single workpiece with the first working spindle and the second working spindle.

  • first and second X-axis adjustment units can be moved so close to each other that the first and second work spindles in the X-axis can be positioned as close as possible to each other, or even directly above one another, thus enabling the simultaneous machining of a single workpiece.
  • first Y-axis guide rail or the second Y-axis guide rail and the third Y-axis guide rail or the fourth Y-axis guide rail are facing each other.
  • a workpiece table gear ring can be arranged between the first and second workpiece tables, with the first and second workpiece tables being rotaryally connected to the workpiece table gear ring.

  • a first synchronizing gear is arranged between the first and third rotary tables, and that a second synchronizing gear is arranged between the second and third rotary tables.
