Definitions
- the present invention relates to a movement and / or positioning device with a five-axis movement and / or positioning of an object.
- the present movement and / or positioning device can be used in particular in machines which move an object in five degrees of freedom, such as, for example, machine tools, processing machines and machines for assembly and handling.
- Known movement and / or positioning devices frequently use arrangements of a plurality of movement platforms which are connected to one another and are based on one another and have a serial construction of corresponding movement axes of the movement platforms.
- Such serial arrangements are implemented, for example, in conventional machine tools with two movement platforms, the drive axes of such a conventional machine tool building on one another. This means that a first axis carries a subsequent second axis, which is usually arranged orthogonally to the first axis.
- Parallel kinematics are an alternative.
- This also includes the movement and / or positioning devices, which are generally referred to as hexapods, and which have six guide chains, which are also referred to as struts, each with five degrees of joint freedom, with the struts (guide chains) generally being prevented from rotating about their own longitudinal axis.
- the struts each have a joint with three degrees of freedom and a further joint with two degrees of freedom, one joint per drive chain being designed as a drive.
- the drive of the guide chains is designed as a rotary or thrust drive, which is mounted in a frame or integrated in the guide chain.
- such hexapods thus have six degrees of freedom of movement. Since a body to be moved or positioned basically has six degrees of freedom, six drives are also required to influence all six degrees of freedom. Most processing machines, however, only need five controllable degrees of freedom. This applies e.g. for a milling machine in which the sixth degree of freedom represents the rotation about the axis of the milling spindle.
- a disadvantage of known hexapods is therefore that six drives have to be used to generate five controlled degrees of freedom.
- Arrangements are also known for generating five-axis movements with five drives, which are arranged in parallel and in series.
- five drives which are arranged in parallel and in series.
- struts three variable-length guide chains (hereinafter also referred to as struts) in parallel between a frame and a slide.
- all five axes are moved, although these axes cannot be controlled separately.
- the specimen slide has two further serially arranged pivoting axes.
- a disadvantage of such an arrangement is that the serially arranged pivot axes, which must be active for all movements in space, limit a dynamic of the movement and / or positioning device.
- the increased mass, which the drives of the variable-length struts have to move, is disadvantageous.
- No. 4,569,627 proposes a movement and / or positioning device in which only three struts are used to connect the specimen slide to the frame. The length of these three struts can be controlled. In addition, two of the three struts can perform a torsional movement.
- a major disadvantage of this movement and / or positioning device is the load on the struts in the torsion or bending direction. Since the rods designed as struts have a high longitudinal stiffness, but are very flexible in the torsion and bending direction, the movement and / or positioning device of this type has a limited overall stiffness and a limited dynamic range.
- the movement and / or positioning device for five-axis movement and / or positioning of an object has a specimen slide and five coupling elements which support the specimen slide in a frame.
- Four of the five Coupling links are each connected to the specimen slide by means of a first joint arrangement, each with two degrees of freedom, and the corresponding further one of the five coupling links is connected with a second joint arrangement with one degree of freedom.
- the movement and / or positioning device forms a parallel kinematics with five coupling links for highly dynamic movement and / or positioning of the object.
- a coupling member (and thus also a drive train) is saved in the present movement and / or positioning device. This ensures a comparatively large working space and in particular also a large angle of attack of the slide. Consequently, the present movement and / or positioning device has a more advantageous ratio between the necessary installation space and usable work space.
- a high degree of rigidity is achieved with the combination of the first and the second joint arrangement on the slide.
- the stiffness necessary for such a highly dynamic movement results in particular from the fact that the forces acting on an object, for example a milling spindle, in a Cartesian coordinate system in all three coordinate directions X, Y and Z are introduced exclusively as longitudinal forces into the coupling elements.
- moments that act on the object in the two swivel directions are only introduced as longitudinal forces into the coupling links.
- the reduction in the number of degrees of freedom of the second joint arrangement has the effect that the rotation of the specimen slide about a longitudinal axis thereof is introduced into the strut, which is connected to the specimen slide by means of this second joint arrangement, as a bending and / or torsional load.
- the rigidity of the present movement and / or positioning device is achieved with comparatively small masses of the machine components, which enables good dynamic properties.
- the movement and / or positioning device also has a high degree of modularity, that is to say a large number of repetitive components.
- the movement and / or positioning device has a first type of first joint arrangements with two joint axes, one of the two joint axes being overlaid with a longitudinal axis of the specimen slide and / or a longitudinal axis of the specimen, and the two joint axes free of intersections are arranged to each other.
- the first of the two joint axes of all the first joint arrangements of the first type are preferably arranged superimposed on the same longitudinal axis of the specimen slide and / or the specimen.
- the two joint axes of the first type on first joint arrangements can be arranged perpendicular to one another.
- first type of first joint arrangements can have a joint ring which rotatably supports the specimen slide about the longitudinal axis of the specimen slide, the joint ring being connected to the associated coupling member via a further joint with a degree of freedom, in particular a hinge joint.
- the present movement and / or positioning device has a second type of first joint arrangement with a cardan joint, in particular a universal joint, with two joint axes, the joint axes of which intersect at a joint point.
- This hinge point of the second type on first hinge arrangements can be arranged on the longitudinal axis of the specimen slide and / or the longitudinal axis of the specimen.
- the aforementioned four of the five coupling links can each be connected to the specimen slide by means of a first joint arrangement of the first type or in each case by means of a first joint arrangement of the second type or by means of first joint arrangements of the first and the second type.
- the second joint arrangement has a joint ring, the joint ring supporting the specimen slide in a rotationally fixed manner about the longitudinal axis of the specimen holder and / or the longitudinal axis of the object and being connected to the associated coupling member via a joint with a degree of freedom, in particular a hinge joint ,
- the modularity of the present movement and / or positioning device is met to a high degree.
- the second joint arrangement can have a joint with a degree of freedom, in particular a hinge joint, this joint directly connecting the associated coupling member to the specimen slide and supporting the specimen slide in a rotationally fixed manner about the longitudinal axis of the specimen.
- the coupling links are each mounted in the frame by means of a cardanic suspension with two degrees of freedom.
- the distance between the individual gimbals and the first joint arrangements and the second joint arrangement is variable in length.
- the coupling members can be designed as threaded spindles, the threaded spindles in the gimbals each being received in a holding device with an internal thread, in particular a nut, and the nut being rotatable with respect to a longitudinal axis of the threaded spindles by means of a drive device.
- a length-variable device in particular a lifting cylinder, can be arranged between the first joint arrangements and the second joint arrangement, wherein a degree of freedom of rotation about a longitudinal axis of the lifting cylinder is made possible by means of a drive device.
- a distance between the individual cardanic suspensions and the first joint arrangements or the second joint arrangement is designed to be invariable in length, the cardanic suspensions being each arranged to be movable along an axis in space, in particular along a longitudinal axis of the coupling links.
- the movement and / or positioning device according to the invention is designed in particular as a processing machine, the object comprising a spindle and the specimen holder comprising a spindle housing.
- the present movement and / or positioning device preferably has a machine table with a further axis of rotation, in particular for receiving a workpiece to be machined.
- the axis of rotation of the machine table can be superimposed on the longitudinal axis of the specimen slide and / or the longitudinal axis of the specimen.
- the movement and / or positioning device can comprise a control unit for controlling the movement and / or positioning of the specimen slide and / or the specimen.
- the control unit can be designed to be programmable, in particular as an NC control unit.
- the NC control unit can contain exactly five programming axes, the NC control unit having a program module for generating six machine axes from the five programming axes specified in the program, and the six machine axes being assignable to the individual coupling links and the axis of rotation of the machine table.
- the program module of the NC control unit can be provided for calculating a quality criterion and an extreme value for the quality criterion, an adjustment of the axes of rotation of the machine table being determinable by means of the extreme value.
- the frame is designed as an icosahedron, the gimbals being arranged on selected surfaces thereof.

- the Z axis denotes the vertical axis of the Cartesian coordinate system in space, which can include a z axis in the coordinate system of the (machine) frame 12 and a z axis in the coordinate system of the slide 1.
- the z axis in the coordinate system of the (machine) frame 12 and the z axis in the coordinate system of the slide 1 are identical only in the center position of both axes.
- FIG. 3 An XN plane spanned by the other axes of the Cartesian coordinate system is defined in FIG. 3 by the machine table.
- the slide 1 and thus also the milling spindle 2 is pivoted with respect to the Z axis and in a plane parallel to the XN plane.
- Such a pivoting movement is shown in FIG. 3, the slide 1 being pivoted in the position shown in FIG. 3 with respect to the Z axis and in a plane parallel to the XN plane
- the specimen slide 1 passes through five hinge rings 3, 3a, the specimen slide 1 being accommodated in four of the five hinge rings 3 so as to be rotatable about the longitudinal axis of the specimen slide 1.
- the further, fifth articulated ring 3a is fixedly connected to a tubular jacket surface of the slide 1, whereby the same is rotationally fixed with respect to the longitudinal axis of the slide 1.
- Each of the five articulated disks 3, 3a shown can be selected for the rotationally fixed connection.
- the only decisive factor is that the specimen slide 1 is accommodated in a rotationally fixed manner in one of the articulated rings 3a and rotatably in the corresponding further articulated rings 3 with respect to the longitudinal axis of the specimen slide 1.
- the articulation rings 3, 3a are arranged in two groups with once three and once two articulation rings, these two groups are arranged at a greater distance from each other.
- Such a grouping and a distance between such groups can be selected on the basis of the structural framework with regard to the available installation space, the necessary work space and the necessary swivel angle.
- each of the five joint rings 3, 3a is connected to a further joint 4, each with one degree of freedom.
- This first joint arrangement each consisting of a joint ring 3 and a joint 4, consequently has a first joint axis which coincides with the longitudinal axis of the specimen slide 1.
- the spindle axis i.e. the longitudinal axis of the object 2 is arranged in the exemplary embodiment shown so that it coincides with this joint axis of the first joint arrangement.

- the movable components of the joints 4 with a degree of freedom are firmly connected to coupling elements 5, which are designed as threaded struts in the exemplary embodiment shown in FIGS. 1, 1a and 3. Consequently, the present movement and / or positioning device in the exemplary embodiment shown has five threaded struts 5, which lead to a holding device with an internal thread on the frame side, in this exemplary embodiment a nut 6 in each case.
- the nuts 6 are each attached to a gimbal 7 with two degrees of freedom.

- the outer ring in turn is mounted in the frame 12 of the present movement and / or positioning device so as to be rotatable about an axis of the outer ring.
- the axes of the inner and outer rings are arranged perpendicular to each other.
- the nuts 6 are rotated relative to the gimbal 7 by means of individual drive devices with respect to the longitudinal axis of the threaded struts. Such a rotation of the nuts 6 changes a distance between a center point of the individual gimbals 7 and the object 2, that is to say in the exemplary embodiment shown the milling spindle.
- the milling spindle 2 can be moved in five degrees of freedom.
- FIGS. 1, 1a and 3 show a movement and / or positioning device with five coupling members (struts) which connect a frame to an object 2 to be positioned, four of the five struts having first joint arrangements, each of which has two degrees of freedom have, and a strut with a second joint arrangement, which has a degree of freedom, are connected to the slide 1.
- One of the joint axes of the first joint arrangement is coaxial with the longitudinal axis of the specimen slide 1.
- the two joint axes of the first joint arrangement, which each have two degrees of freedom are arranged without intersection with one another.
- an embodiment is shown with five identical joint combinations, each with two degrees of freedom, the identical joint combinations each having a joint ring 3, 3a and a further joint 4 with one Include degree of freedom, with four of the joint combinations rotatable about the longitudinal axis of the slide 1 and one of the joint combinations are rotatably formed about the longitudinal axis of the slide 1.
- FIGS. 1 and 1a show a further exemplary embodiment of the present movement and / or positioning device for five-axis movement and / or positioning of an object.
- one of the joint rings 3 from the exemplary embodiment shown in FIGS. 1 and 1a, which receive the specimen slide 1 in a rotatable manner, is replaced by a cardan joint, in this exemplary embodiment a universal joint 8.
- the hinge axes of this universal joint 8 intersect at a hinge point 9, this hinge point 9 being arranged on the longitudinal axis of the object holder 1.
- the longitudinal axis of the slide 1 coincides with the spindle axis in this exemplary embodiment.
- FIGS. 2 and 2a has three further articulation rings 3 which receive the specimen slide 1 so that it can rotate with respect to the longitudinal axis thereof.
- FIGS. 2 and 2a has an articulated ring 3a which supports the specimen slide 1 in a rotationally fixed manner about the longitudinal axis thereof.
- FIGS. 2 and 2a correspond to the features of the embodiment described in connection with FIGS. 1 and 1a.
- FIGS. 2 and 2a has a universal joint 8 with two degrees of freedom and hinge axes intersecting in a hinge point 9, this hinge point 9 being arranged on the longitudinal axis of the specimen slide 1.
- one of the struts is connected to the specimen slide with exactly one degree of freedom via a second joint arrangement.
- the second joint arrangement is thus reduced by one degree of freedom compared to the first joint arrangement of the remaining struts.
- the struts 5 are connected to the frame 12, as already explained at the beginning, via cardanic suspensions 7, each with two degrees of freedom.
- the struts 5 are designed as threaded spindles 5, a feed movement of the struts 5 being realized by rotating the nut 6 about the longitudinal axis of the corresponding threaded spindle.
- the respective nut 6 is firmly connected to it, i.e. relative to the gimbal 7, the nut 6 only has a degree of freedom of rotation about a longitudinal axis of the corresponding threaded spindle 5.
- lifting cylinders can be arranged between the gimbals 7 and the first articulated arrangements 3, 4 or 8 or the second articulated arrangement 3 a, 4.
- a further degree of freedom for rotating the struts about the strut axis is realized by arranging a drive.
- One side of the lifting cylinder is received in the cardanic joints, the other side is connected to the first joint arrangements or the second joint arrangement.
- the present movement and / or positioning device is not limited to such a change in the distance.
- movement and / or positioning of the object 2 can be realized by moving the gimbals 7 along a controllable axis in space.
- this controllable axis can each be arranged along the longitudinal axis of the individual coupling elements 5.
- the work space that can be used in the present movement and / or positioning device is limited on the one hand by the collision areas of the struts 5, and on the other hand the rigidity decreases at certain positions in the work space. As a result, not all swiveling movements of the object 2 or the object carrier 1 can be reached or should be avoided due to the lower rigidity.
- the usable work space can be expanded by adding a further (redundant) axis of rotation (also referred to as an additional axis), which is arranged in the machine table 10, which enables full 5-sided machining of the workpiece 11.
- the axis of rotation of the machine table 10 can coincide with the Z axis.
- the additional axis works in conjunction with the parallel kinematics with five struts described above.
- FIG. 3 Such an embodiment with a rotatable machine table 10 is shown in FIG. 3.
- the spindle 2 is pivoted in the position shown by about 90 ° with respect to the Z axis.
- a further pivoting movement in a plane parallel to the XN plane cannot be carried out without restriction, since collisions between the coupling elements 5 would occur.
- With the machine table 10 accessibility to the workpiece 11 is achieved on all five sides.
- the high dynamic of the parallel structure remains unrestricted for local movements, whereby the machine table 10 does not necessarily have to have a high dynamic.
- a further enlargement of the work area is possible by integrating the entire arrangement into further movement devices, in particular in so-called portal systems.
- the NC control is provided with a program module which divides the programming axes into the real ones existing six machine axes (coupling links 5 and axis of rotation of the machine table).
- the controller calculates a quality value (quality criterion) at the time the acceleration and jerk values of the axes are limited (see look-ahead), in which the machine stiffness at the working point and the distance from collision areas are incorporated.
- the redundant additional axis (s) are controlled so that this quality value is as large as possible.
- the NC program can be created in five axes, the control unit generating six machine axes from these five programming axes by calculating a quality criterion in the control unit and determining an extreme value (minimum or maximum) for this quality criterion. This uniquely determines the position of the sixth axis.
- the control unit can thus convert five programming axes into six machine axes in real time by evaluating the additional quality criterion, for example a distance to prohibited areas or a rigidity of the arrangement, and searching for the extreme value.
- NC programs for conventional five-sided machining can be run without adaptation to the combined machine system.
- the result is a strategy for the control which allows NC programs for five axes (coupling links) to be be able to process effectively if the machine has more than five axes (redundant axes).
- the frame is designed as an icosahedron.
- the outer joints of the coupling links 5, that is to say the cardanic joints 7, are each arranged on a surface of the icosahedron base body, the icosahedron base body guaranteeing a high degree of rigidity.
- a corresponding selection of the icosahedron surfaces on which the individual cardanic joints 7 are arranged depends on a desired arrangement of the struts (coupling links) relative to the slide 1, the desired arrangement of the coupling links 5 determining the required working space and the necessary pivoting angles of the slide 1 becomes.
