Definitions

  • a machine tool in which one or more work spindle units are arranged suspended on a bridge unit.
  • the bridge unit can be pivoted about a vertical axis, so that the work spindle unit or working spindle unit units can be arranged within different processing sectors.
  • Each work spindle unit is movable relative to the vertical axis in the radial direction and in the vertical direction on the bridge unit.
  • a machine tool having the features of claim 1. Because at most two work spindles are arranged on the spindle carrier, the spindle carrier can be made much simpler, so that the mass to be accelerated and braked is small. The entire structure of the machine tool can be simplified thereby.
  • the pivot axis can be used not only to move the respective work spindle from one machining position to the next machining position, but also to position the workpiece to be machined relative to a tool.
  • the pivot axis of the spindle carrier is thus a complete rotary machining axis (C axis). This makes it possible to simplify the processing stations since linear infeed axes required in the prior art can be omitted.
  • the spindle axis can be positioned exclusively by pivoting the spindle carrier in the horizontal x-direction and the horizontal y-direction, ie along the circular arc, the machining of a workpiece on a linearly non-movable processing station is effected exclusively by the numerically controlled pivot axis (C -Axis) of the spindle carrier and / or the numerically controlled linear axis (z-axis), which is provided by the linear movability of the work spindle in the z-direction.
  • C -Axis the numerically controlled pivot axis
  • z-axis numerically controlled linear axis
  • the pivot axis is a full-fledged machining axis
  • a variety of processing steps with simple structure processing stations are possible, which are not linearly movable, ie fixed in any linear direction, are arranged on the base frame.
  • linear machining axes for advancing the tools can be saved.
  • control unit For positioning the workpieces during machining, the control unit is designed such that a coordinate transformation from a Cartesian coordinate system into a polar coordinate system can be carried out. Linear machining coordinates, such as linear turning paths, can thus be converted by means of the control unit into polar coordinates, with which the control unit then controls the pivoting of the spindle carrier.
  • the spindle carrier can preferably be swiveled through 360 °, so that a For machining shaft-shaped workpieces, a tailstock with an axis of rotation running in the z-direction can be arranged on the base frame
  • the wave-shaped workpiece received in the work spindle can be arranged vertically aligned with the tailstock and by moving the work spindle in the z-direction on a centering point of the tailstock so that machining of the wave-shaped workpiece can take place.
  • a machine tool according to claim 2 allows a simple independent supply and removal of workpieces.
  • a base frame according to claim 3 allows a simple lateral arrangement of the stations on the base frame or on the sides of the base frame.
  • a machine tool according to claim 4 allows easy feeding and removal of workpieces from one side.
  • a machine tool according to claim 5 allows a workpiece flow through the machine tool.
  • a machine tool according to claim 6 allows the arrangement of a plurality of stations on the base frame. This is particularly advantageous when arranged on the common side of the base frame, a first, linearly non-movable processing station and a second, in at least one horizontal direction, ie in the x and / or y-direction, movable second processing station is. In this case, the simultaneous machining of a workpiece with two tools or processing stations can follow. The pivoting of the workpiece due to machining with the tool of the first processing station can be compensated by a linear method of the tool of the second processing station.
  • a machine tool according to claim 7 allows a fast and high-precision pivoting of the spindle carrier. Due to the gearless direct drive, the workpiece to be machined can be positioned with high precision during its machining by pivoting the spindle carrier relative to the tool. This is particularly advantageous if the tool or the associated processing station is not linearly movable, so that the positioning of the workpiece in the horizontal x and y direction takes place exclusively by pivoting the spindle carrier.

  • a machine tool according to claim 10 ensures high flexibility in the machining of two workpieces. During the machining of a workpiece, for example, another workpiece can be picked up or stored. Furthermore, two workpieces can be processed simultaneously.
  • a machine tool according to claim 1 1 is extremely simple in construction, since none of the processing stations has linear machining axes.
  • a machine tool according to claim 12 ensures a high flexibility in the processing of the workpieces. If two workpieces are processed simultaneously, the unwanted pivoting of one workpiece due to the processing of the other workpiece can be compensated by a linear process of the tool turret. In addition, workpieces can be processed in a wavy manner by the method in the x and z directions.
