    The invention relates to a machine tool with two work spindles and two workpiece tables for receiving workpieces.
    So-called double-spindle machines are known from WO 2005/025801 A1 and WO 00/37213 A2. In such double-spindle machines, two workpieces can be machined simultaneously with one tool inserted into each of the tool spindles. Both tool spindles and thus both tools are moved synchronously in the three axes of the coordinate system, so that identical machining processes take place on the two workpieces.
    The double-spindle machines known from WO 2005/025801 A1 and WO 00/37213 A2 have the disadvantage that, due to their structure, the maximum length of the workpiece that can be machined is limited.
    The object of the present invention was to overcome the disadvantages of the prior art and to provide a machine tool by means of which workpieces of great length can be machined.
    This object is achieved by a device according to the claims.
    According to the invention, a machine tool is formed which comprises the following components:
    a machine frame;
    a spindle adjustment device which is arranged on the machine frame; at least a first work spindle, which is rotatably mounted about a first spindle axis, and a second work spindle, which is about a second spindle axis
    2.23
    N2016 / 26100-AT-00 is rotatably mounted, the work spindles being accommodated on the spindle adjustment device and by means of the spindle adjustment device in a vertical Z-axis, in a horizontal X-axis and in a Y arranged at right angles to the Z-axis and X-axis -Axis are adjustable relative to the machine frame;
    a workpiece clamping device which is arranged on the machine frame and is designed for receiving at least a first workpiece and a second workpiece.
    The spindle adjustment device comprises a working head on which the two working spindles are arranged, the working head being pivoted about a working head pivot axis which is aligned parallel to the Y axis, and the workpiece clamping device comprising at least a first workpiece table and a second workpiece table, the first Workpiece table is pivotally mounted about a first pivot axis, which is aligned parallel to the X-axis, and the second workpiece table is pivotally mounted about a second pivot axis, which is aligned parallel to the X-axis, and that the first work spindle is assigned to the first workpiece table and the second work spindle is assigned to the second workpiece table.
    An advantage of the machine tool according to the invention is that a separate workpiece table is provided for each of the two workpieces, which can be pivoted about its own pivot axis. As a result, two workpieces with a large longitudinal extension can be clamped in the present machine tool and machined parallel to one another.
    Of course, it can also be provided that the machine tool also has other work spindles in addition to the first work spindle and the second work spindle. For this purpose, further workpiece tables can also be provided, which are assigned to the work spindles.
    Furthermore, it can be expedient if the spindle adjustment device has a main adjustment unit which is coupled to the machine frame by means of an X-axis linear guide and along the X-axis relative to the machine
    N2016 / 26100-AT-00 sliding frame and that the spindle adjustment device has a height adjustment unit which is coupled to the main adjustment unit by means of a Z-axis linear guide and can be displaced along the Z axis relative to the main adjustment unit and that the spindle adjustment device has an extension unit, which is coupled to the height adjustment unit by means of a Y-axis linear guide and is displaceable along the Y axis relative to the height adjustment unit, the working head being coupled to the extension unit by means of a pivot bearing and being pivotable about the axis of the working head relative to the extension unit. This arrangement allows the machining tools to be positioned in a targeted manner relative to the workpieces to be machined.
    Furthermore, it can be provided that the two workpiece tables are each coupled to the machine frame by means of a first pivot bearing and by means of a second pivot bearing, both workpiece tables having a workpiece clamping area which is formed in each case between the two pivot bearings. The advantage here is that this design allows the workpiece tables to be freely rotated with respect to their pivot axis and to accommodate workpieces with a large longitudinal extension.
    In addition, it can be provided that the workpiece clamping area with respect to the X axis has a usable workpiece clamping length between 1000mm and 8000mm, in particular between 1400mm and 5000mm, preferably between 1500mm and 2500mm. This allows workpieces with a large longitudinal extension to be clamped on the workpiece table.
    Also advantageous is an embodiment according to which it can be provided that the first spindle axis of the first work spindle and the second spindle axis of the second work spindle are arranged at a distance from one another with respect to the Y axis.
    According to a development, it is possible that the distance between 200mm and 1500mm, in particular between 300mm and 1000mm, preferably between
    4.23
    N2016 / 26100 AT-00
    Is 400mm and 600mm. With such a dimensioning, a large number of workpieces to be produced can be clamped.
    Furthermore, it can be provided that an adjusting device is arranged in the working head, by means of which the distance between the first spindle axis of the first working spindle and the second spindle axis of the second working spindle can be adjusted to one another. The advantage here is that this measure can be used to compensate for dimensional differences that can occur due to thermal expansion in the working head and / or in the workpiece clamping device. The adjustment device can have different types of actuators, by means of which the distance can be adjusted.
    Furthermore, it may be expedient if the first pivot axis of the first workpiece table and the second pivot axis of the second workpiece table are arranged offset from one another with respect to the Y axis.
    In addition, it can be provided that the distance between the first spindle axis of the first work spindle and the second spindle axis of the second work spindle and the distance between the first pivot axis of the first workpiece table and the second pivot axis of the second workpiece table are the same. This measure allows the two workpieces to be machined synchronously with one another.
    Furthermore, it can be provided that the two workpiece tables are driven in their rotational movement about the pivot axes by a common drive unit. The advantage here is that an additional drive can be saved by this measure. It also ensures that the two workpiece tables are moved synchronously with each other.
    According to a special embodiment, it is possible for the common drive unit to be coupled to the two workpiece tables by means of a worm gear.
    Alternatively, it can be provided that the common drive unit is coupled to the two workpiece tables by means of a toothed belt.
    23.5
    N2016 / 26100 AT-00
    In particular, it can be advantageous if the drive unit is designed in the form of a torque motor. The advantage here is that such a torque motor is designed with a high positioning accuracy at the same time to apply a large torque.
    Furthermore, it can be provided that the spindle axes of the two working spindles are parallel to the Z axis in an un pivoted position of the working head.
    In addition, it can be provided that the two workpiece tables can only be pivoted about the X axis and are otherwise not movable relative to the machine frame. The advantage here is that this measure requires the smallest possible number of independent drives and the machine tool has a great variety in terms of their possible movement. In addition, this measure makes it possible for the machine tool to have the smallest possible dimensions, since the workpieces do not have to be rotated about their vertical axis which is normal to the longitudinal axis of the longitudinal extent.
    Also advantageous is a configuration according to which it can be provided that the two work spindles are driven in their rotational movement about the spindle axes by a common drive unit, in particular that the common drive unit is coupled to the two work spindles by means of a toothed belt. The advantage here is that a separate drive is not required for each work spindle. In other words, it can be provided that the work spindles for driving them have a force transmission means, such as a pulley. Since it is not relevant for production that the two work spindles run at right angles to one another, it can also be provided that a V-belt or another drive means is used instead of the toothed belt.
    For a better understanding of the invention, this will be explained in more detail with reference to the following figures.

The Y-axis linear guide 17 can be designed, for example, in the form of a telescopic arm. Alternatively, it is conceivable that the Y-axis linear guide 17, for example, also comprise guide carriages which are coupled to a guide rail.

    N2016 / 26100 AT-00
    In addition, the working head 4 is pivotally mounted on the extension unit 16 by means of a swivel bearing 18 with respect to a swiveling head 19.
    The working head pivot axis 19 is aligned parallel to the Y axis 11. The working head pivot axis 19 and the two spindle axes 7, 8 are preferably in one plane and are arranged at right angles to one another.
    Due to the described construction of the spindle adjustment device 3, the working head 4 can be displaced with respect to the machine frame 2 in the Z-axis 9, in the X-axis 10 and in the Y-axis 11 and rotated with respect to the working head pivot axis 19 lying parallel to the Y-axis 11.
    In addition, the machine tool 1 comprises a workpiece clamping device 20, which is used to hold workpieces to be machined. The workpiece clamping device 20 has a first workpiece table 21 and a second workpiece table 22. The first workpiece table 21 can be pivoted relative to the machine frame 2 with respect to a first pivot axis 23. The second workpiece table 22 can be pivoted relative to the machine frame 2 with respect to a second pivot axis 24. The two pivot axes 23, 24 of the two workpiece tables 21, 22 are arranged parallel to the X axis 10. In particular, it is provided that the first workpiece table 21 is used to hold a first workpiece and the second workpiece table 22 is used to hold a second workpiece, the outer contour of the first workpiece and the second workpiece being identical to one another and the same machining steps being carried out on the two workpieces become. For the sake of clarity, the two workpiece tables 21, 22 are also only shown rudimentarily in FIG. 1. A wide variety of fastening options can of course be provided for fastening the workpieces to the workpiece tables 21, 22.
    The first workpiece table 21 is rotatably mounted on the machine frame 2 by means of a first pivot bearing 25 and a second pivot bearing 26. Analogously, the second workpiece table 22 is rotatably mounted on the machine frame 2 by means of a first pivot bearing 27 and a second pivot bearing 28.
    23.9
    N2016 / 26100 AT-00
    The pivot bearings 25, 26, 27, 28 can be designed, for example, in the form of bearing blocks, which corresponding receptacles are attached to the workpiece table 21.
    As can be seen from FIG. 1, it can be provided that the first workpiece table 21 has a workpiece clamping area 29 which extends between the first pivot bearing 25 and the second pivot bearing 26. Analogously, it can be provided that the second workpiece table 22 has a workpiece clamping area 30 which extends between the first pivot bearing 27 and the second pivot bearing 28 of the second workpiece table 22.
    The workpiece clamping area 29 of the first workpiece table 21 has a workpiece clamping length 31. The workpiece clamping area 30 of the second workpiece table 22 has a workpiece clamping length 32. It is preferably provided that the first workpiece table 21 and the second workpiece table 22 are of identical design.
    In order to be able to use the entire workpiece clamping length 31, 32 of the two workpiece tables 21, 22, it can be provided that the X-axis linear guide 13 of the main adjustment unit 12 by this amount of the workpiece clamping length 31, 32 plus twice the distance from the working head pivot axis 19 to the tool tip is movable. As a result, the end faces of workpieces with a maximum length that corresponds to the workpiece clamping length 31, 32 can still be machined. The two work spindles 5, 6 and the two spindle axes 7, 8 are arranged at a distance 33 from one another. The distance 33 extends in the direction of the Y axis 11.
    The two workpiece tables 21, 22 and the two pivot axes 23, 24 are arranged at a distance 34 from one another. The distance 34 also extends in the direction of the Y-axis 11. The configuration described means that the first work spindle 5 is assigned to the first workpiece table 21 and that the second work spindle 6 is assigned to the second workpiece table 22.
    10/23
    N2016 / 26100 AT-00
    In one embodiment variant, it can be provided that a
    Adjustment device is arranged, by means of which the distance 33 of the first spindle axis 7 of the first work spindle 5 and the second spindle axis 8 of the second work spindle 6 can be adjusted to one another.
    As an alternative to this or in addition to this, provision can be made for an adjustment device to be arranged in the workpiece clamping device 20, by means of which the distance 34 between the two workpiece tables 21, 22 or between the two pivot axes 23, 24 can be adjusted.
    By means of the machine tool 1 according to the invention, two workpieces which are of identical construction can be machined parallel to one another. The first workpiece is clamped on the first workpiece table 21 and the second workpiece on the second workpiece table 22. The tool of the first work spindle 5 processes the first workpiece and the tool of the second work spindle 6 processes the second workpiece. Due to the construction of the machine tool 1 according to the invention, the machining of the first workpiece and the second workpiece takes place synchronously. Thus, two workpieces can be machined simultaneously using a machine tool 1 that is as simple as possible, whereby the utilization of the machine tool 1 or its productivity can be improved.
    In order to be able to construct the machine tool 1 as inexpensively as possible, it can also be provided that the workpiece tables 21, 22 are pivoted by means of a common drive unit 35. The drive unit 35 can be designed, for example, in the form of a torque motor.
    The torque motor can be coupled to the two workpiece tables 21, 22, for example, by means of a belt drive. Alternatively, it can be provided that the torque motor is coupled to the two workpiece tables 21, 22 by means of a worm gear.
    11/23
    N2016 / 26100 AT-00
    In yet another alternative variant it can be provided that the rotor of the torque motor is integrated directly into the workpiece tables 21, 22 and thus a separate torque motor is formed for each workpiece table 21, 22.
    Furthermore, it can also be provided that the two work spindles 5, 6 are driven by a common drive unit 36. The drive unit 36 can be formed, for example, by a three-phase asynchronous motor which is controlled by a frequency converter.
    Furthermore, it is also conceivable that the drive unit 36 is designed in the form of a synchronous motor.
    Of course, it can also be provided that each of the work spindles 5, 6 is driven by its own drive unit 36. It can be provided here that the work spindle 5, 6 is the rotor of the drive unit 36 at the same time.
    The work spindles 5, 6 of the machine tool 1 shown in FIG. 1 can be displaced with respect to the Z axis 9, the X axis 10 and the Y axis 11 and can be pivoted with respect to a parallel to the Y axis. The workpieces accommodated in the workpiece tables 21, 22 can be pivoted with respect to a parallel to the X axis 10. The work spindles 5, 6 thus have five degrees of freedom with respect to the adjustment relative to the workpiece to be machined.
    The exemplary embodiments show possible design variants, it being noted at this point that the invention is not restricted to the specially illustrated design variants of the same, but rather also various combinations of the individual design variants with one another are possible and this variation possibility is based on the teaching of technical action through the present invention Ability of the specialist working in this technical field.
