Definitions

  • the invention relates to a machine tool.
  • the machine tool known from WO2018209373A1 is difficult to load, especially with large work pieces, since the arrangement of the work spindles prevents easy access to the workpiece tables in such workpieces.
  • the object of the present invention was to overcome the disadvantages of the prior art and to create a machine tool which can be efficiently equipped with workpieces.
  • a machine tool which comprises the following components: a machine frame; a first work spindle which is rotatably mounted about a first spindle axis; a workpiece clamping device, the workpiece clamping device comprising at least one first workpiece table for receiving at least one first workpiece and a second workpiece table for receiving at least one second workpiece, the first workpiece table being mounted pivotably about a first pivot axis and the second workpiece table mounted pivotably about a second pivot axis is, wherein the first pivot axis and the second pivot axis are arranged parallel to each other.
  • the first workpiece table and the second workpiece table are freely accessible with workpieces in a workpiece change direction, the first pivot axis and the second pivot axis being arranged perpendicular to the workpiece change direction at a distance from one another.
  • the machine tool according to the invention has the advantage that the workpiece handling can be improved and thus the efficiency of the machine tool can be increased. Surprisingly, this not only reduces set-up times, whereby machining-specific costs can be reduced, but the energy efficiency of the machine tool can also be improved.
  • the workpiece clamping device comprises a second work spindle which is rotatably mounted about a second spindle axis, the first work spindle being assigned to the first workpiece table and the second work spindle being assigned to the second workpiece table.
  • This has the advantage that two workpieces can be machined simultaneously or synchronously with one another, as a result of which the efficiency of the machine tool can be improved even further.
  • the two working spindles are arranged at a fixed distance from one another, or are arranged on a common working head.
  • the workpiece change direction is aligned vertically and that the first pivot axis and the second pivot axis are spaced apart at a horizontal distance from one another.
  • This has the advantage that the workpieces can be changed easily.
  • lifting devices such as chains or other traction means can be used to change the workpieces, which can only absorb tensile forces.
  • this measure makes the workpiece tables accessible to a workpiece changing device which is arranged overhead. This can be, for example, a rail-guided workpiece changing device.
  • first pivot axis and the second pivot axis are spaced apart from one another at a vertical distance. This has the advantage that the workpieces can be processed easily.
  • An embodiment is also advantageous, according to which it can be provided that an axis plane is formed in which the first pivot axis and the second pivot axis lie, the first spindle axis being arranged perpendicular to the axis plane. Due to the position of the spindle axis relative to the axis plane, a simplified machining of the workpiece can be achieved.
  • the first spindle axis is arranged at an angle between 1 ° and 89 °, in particular between 20 ° and 70 °, preferably between 35 ° and 55 ° to the horizontal.
  • the angle is formed below the horizontal.
  • the spindle axis is directed upwards, so that a machining tool accommodated in the work spindle forms the uppermost point of the spindle axis.
  • Such a position of the work spindle or the machining tool can also be referred to as overhead machining.
  • the first work spindle is displaceable ver by means of a Z-axis linear guide in a Z-axis relative to the machine frame, wherein the Z-axis is arranged parallel to the first spindle axis; is displaceable ver by means of an X-axis linear guide in an X-axis relative to the machine frame, wherein the X-axis is arranged parallel to the first pivot axis; is displaceable ver by means of a Y-axis linear guide in a Y-axis relative to the machine frame, the Y-axis being arranged normal to the Z-axis and the X-axis, the first work spindle being displaceable exclusively with respect to these axes and around its first spindle axis is rotatable.
  • such a construction of the machine tool can be implemented easily and thus less prone to errors or inexpensively and can moreover also have a high level of efficiency when the machine tool is in operation.
  • the machine tool machine can achieve a high level of efficiency if the first work spindle can only be displaced linearly with respect to the specified axes and cannot be pivoted.
  • a workpiece changing device is formed, which is used to change workpieces onto the workpiece tables, the workpiece changing device comprising at least one first lifting device which is used to lift the workpieces vertically.
  • a workpiece changing device designed in this way has a simple and thus efficient structure.
  • the workpieces can be exchanged easily and in a time-saving manner by means of a workpiece changing device designed in this way.
  • first spindle axis and the second spindle axis are arranged at a normal distance from one another and that the first pivoting axis and the second swivel axis are arranged at a normal swivel axis distance from one another, wherein the normal spindle axis distance and the normal swivel axis distance are the same.
  • the first work spindle is arranged on the machine frame in such a way that a tool received in the first work spindle forms the highest point of the first work spindle.
  • the chips incurred during the machining process can be easily transported away, which means that any machining failures due to soiling of the machining tool can be prevented as much as possible.
  • the first workpiece table can be equipped with one of the first workpieces on its front side and on its rear side. This has the advantage that while the first workpiece clamped on the front of the first workpiece table is being processed, a further first workpiece can be exchanged at the same time on the back of the first workpiece table. This can of course also take place at the same time for the second workpiece table or the second workpiece. These measures can further shorten non-productive times or set-up times. Furthermore, it is associated with little effort to carry out the workpiece table for receiving a workpiece on both sides.
  • the Z-axis linear guide and / or the Y-axis linear guide is coupled to a weight compensation system, in particular a hydraulic weight compensation system. This has the advantage that the drives can be relieved and the possible accelerations can be improved.
  • the Z axis is aligned horizontally and the Y axis is aligned vertically, the first workpiece table and the second workpiece table being offset from one another in the direction of the Z axis and the first working spindle and the second Working spindle are arranged offset to one another in the direction of the Z-axis.
  • the Z-axis is aligned horizontally and the Y-axis is aligned vertically.
  • the first workpiece table, the second workpiece table and possibly further workpiece tables are arranged offset from one another in the direction of the Z axis.
  • the individual workpiece tables are accessible from above, so that the machining tools can be lifted from the workpiece tables, for example by means of a crane that moves in from above.
  • this measure can ensure that chips from a machining tool of an upper work spindle cannot fall onto a machining tool of a lower work spindle, where they could interfere with the machining process.
  • the first workpiece table in particular the uppermost workpiece table, is arranged offset in the direction of the Z-axis as far as possible towards the main adjustment unit.
  • the second workpiece table can be spaced further from the main adjustment unit in the direction of the Z axis than the first workpiece table.

  • the individual work spindles are also arranged offset from one another in the direction of the Z-axis.
  • the offset of the individual work spindles in the direction of the Z-axis is the same as the offset of the individual workpiece tables in the direction of the Z-axis.
