Definitions
- the invention relates to a tool coupling for connecting an exchangeable tool head to a machine tool, with an at least partially or completely tapered or cylindrical hollow shaft and an annular contact collar, which interact with a correspondingly designed receiving bore and an annular counter surface of a basic holder on a machine tool, the basic holder and the tool coupling can be locked by means of clamping elements which can be actuated via a clamping device so that the contact collar of the tool coupling rests on the counter surface of the basic holder, and with a circumferential gripper groove provided on the tool coupling for a gripping device during automatic tool change.
- Couplings of this type are known, for example, from EP 0 343 190 B1, the latter coupling working with balls as clamping elements which are driven radially outward into existing openings when clamping the tool and radially inward when the tool is released via a clamping rod.
- Another comparable tool coupling with wedge-shaped clamping elements shows and describes DE 38 07 140 C2.
- a hollow taper shank which has a slight excess in the area of elastic deformability compared to the corresponding locating bore, can create a high axial stiffening with static and dynamic loading in connection with the mutual plane contact, which the tool coupling as a connection between a tool holder and a Basic holder, possibly in the form of a machine tool spindle holder, which can be used on machine tools for turning, drilling and milling.
- a machine tool can be used as a machining center with which a variety of machining operations can be carried out.
- so-called tool change systems are becoming increasingly important, with a gripper groove being provided instead of a manual tool change for changing the tool head on this or on the tool coupling.
- a tool head with the tool coupling which can also be designed as a separate intermediate piece for receiving and fastening a tool head, in a machine tool spindle or a basic holder on the one hand and in a tool magazine, for. B. a turret, on the other hand to be able to precisely align with respect to the angle of rotation setting, further positioning elements are required.
- stops arranged on the outer jacket of the tool coupling or other switching and alignment surfaces in connection with positioning elements such as pins in the basic holder or a machine spindle are used.
- switching and alignment surfaces are provided on diametrically opposite lateral surfaces of the tool coupling.
- the different borehole contours of the diametrically opposed blind boreholes can also be manufactured in such a way that, statically and dynamically (in the case of rotations), the masses "taken away" by the recesses are completely, or at least essentially, compensated.
- the blind bores also have the advantage that, in conjunction with positioning pins, they enable the tool coupling to be aligned precisely both axially and in terms of the angle of rotation, so that incorrect tool positions are practically excluded.
- the blind bores are preferably arranged centrally to the gripper groove, and they furthermore preferably have a larger diameter - at least in the upper region - than the groove width.
- the blind boreholes can have an upper region in cross-section, a region with a wider diameter and a further region with a smaller diameter adjoining the bottom of the borehole.
- the diameters in the upper region are preferably of the same size selected.
- the lower region of the stepped blind hole has a smaller, but possibly different, diameter on opposite sides.
- one of the blind holes in the lower region can have a smaller diameter but a greater depth and vice versa on the other side a comparatively larger diameter but a smaller depth.
- the geometrically different configuration can also be realized by a partially conical bottom of the borehole or a flat bottom of the borehole. This effectively prevents 180 ° rotation angle interchanges in the tool coupling according to the invention.
- microchips are known from the prior art for tool identification and are integrated on or in the tool coupling. The best possible legibility is ensured if the microchips are arranged on the outer casing of the carrier body in question. If, according to a further embodiment of the invention, a tool coupling is used with additional two further diametrically opposed blind bores, which are offset by 90 ° to the already described bores (with different borehole contours), the microchip can be attached in one of these bores. Due to the radial displacement of the microchip towards the inside, the microchip is adequately protected against mechanical external influences.
- These additional further diametrically opposite bores have an identical or substantially identical borehole contour. While one of the additional holes is used to hold the microchip, the opposite hole eliminates the static dynamic imbalance.
- These two bores are preferably flat, that is to say that they have a larger diameter than the dimension of their depth.
- the diameter of the bores can be chosen to be as large as the diameter of the upper regions of the two blind holes with different borehole contours.
- each of these additional bores can, if required, be used in the same way as previously described for the blind bores, so that in principle four bores, each offset by 90 °, can be used for positioning or aligning the tool head.
- the entirety of the four existing blind holes is designed in the form of two pairs of holes located opposite each other in such a way that the tool coupling is fully balanced.
- the tool couplings can have a different size, which is adapted to the size of the spindles used or other adapters and intermediate pieces.
- the usual system sizes are 32 mm to 160 mm, preferably between 40 mm and 100 mm.
- Usual diameter dimensions are 40 mm to 80 mm.
- the diameter dimensions preferably differing between 10 mm and 20 mm, in particular between 10 mm and 16 mm.
- the blind holes with different borehole contours are arranged in a plane perpendicular to the connecting line of openings in the hollow shaft for locking the clamping elements, based on an end view of the tool coupling. Accordingly, the additional blind holes, one of which carries the microchip, are offset by 90 °.
- FIG. 1 is a perspective view of a tool coupling according to the invention
- Fig. 4 is a sectional view of this tool coupling in the area of the blind holes
- Fig. 5 to 7 respective blind hole cross-sections.
- the tool coupling shown in Fig. 1 has a hollow shaft 10 with a tapered outer surface, which has opposite openings 11, by means of which the tool coupling can be fixed in a machine spindle in conjunction with spherical clamping elements, not shown. Furthermore, the tool coupling has an annular contact collar which interacts with an appropriately designed annular counter surface of a basic holder on the machine tool. Tool couplings of this type are described in detail, for example, in EP 0 343 190 B1. In addition, the tool coupling has an essentially V-shaped circumferential gripper groove 13, into which a gripper device (not shown) can engage when changing the tool. At the end opposite the hollow shaft 10, the actual tool head is attached as a tool carrier (not shown).
- the tool coupling has two first diametrically opposite blind holes 14 and 15, the different cross sections of which are shown in FIGS. 5 and 6. These bores or their connecting line are perpendicular to the connecting line of the two above-mentioned openings 11 in the hollow shaft 10.
- Flat bores 16 each of the same design in the drilling contour are offset by 90 ° and diametrically opposite, the connecting line of which is arranged parallel to the connecting line of the two openings 11 ,
- the bore 16 visible in FIG. 1 serves here as a compensating bore for eliminating the imbalance that would arise if the opposite bore 16, in which a microchip is arranged, were arranged alone.
- This microchip contains a data memory in which the identification codes for the tool in question are contained.
- the bores 14, 15 and 16 are arranged centrally to the gripper groove, as is clear from FIGS. 2 and 3.
- the bore 16 has an essentially uniform diameter a of 10 mm with a smaller borehole depth b of 5.4mm.
- the bore can deviate slightly from a cylindrical shape and can be conically tapered towards the open end.
- a microchip is arranged in one of the bores 16 and contains a memory with readable information for tool identification. This arrangement of the microchip in the bore 16 protects this microchip against external mechanical damage.
- This bore 14 is used for the controlled positioning of the tool coupling in the machine-side receptacle (spindle or basic holder), in which, for example, spring-loaded pins with a conical end in the basic holder can be determined when the tool coupling and thus the tool head have reached the desired angle of rotation.
- the opposite bore 15 instead has a lower, cylindrical region 19 with a smaller diameter than the upper region 17, but this bore is considerably shallower, i. H. trained with a lower borehole depth.
- the bore 15 is used in conjunction with corresponding positioning pins to orient the tool coupling in a magazine.
