Description

[0001] The present invention is a divisional application with application date of December 16, 2020, application number 202080086673.7, and invention name “Tool component connected to tool pair accessory, tool pair accessory connected to tool component and tool”. Technical Field

[0002] The invention relates to a tool component configured to be connected to a tool counter-accessory, a tool counter-accessory configured to be connected to the tool component, and a tool having such a tool component and such a tool counter-accessory. Background Art

[0003] Complex tools consist of various components, so that in particular the machining head (also called interchangeable head) can be replaced as required or replaced in the event of wear or damage. Joints or interfaces are provided between the individual components of such tools, via which the individual components are mechanically connected to one another and aligned with one another. Such interfaces can also be used to extend or shorten the tool as required. The tool should be able to be connected and disconnected easily and quickly in the area of ​​the interface, and the components should also be aligned with one another as precisely as possible - in particular with regard to the axial and radial position.

[0004] Patent document DE 10048910A1 discloses a joint in which a hollow conical concave part and a conical convex part cooperate to provide radial centering, and in the connected state the flat surfaces abut against each other to define the axial position. In the assembled state of the joint, the two parts of the tool are clamped to each other in the axial direction by a clamping device. Such a joint or interface is also called an HFS interface.

[0005] In the case of such joints, the individual components are usually clamped to one another by means of a double-thread screw, see for example also patent document DE 10112966A1. This requires an additional component, namely the double-thread screw, and at least one further component for actuating it. In addition, the production of the internal thread engaging the double-thread screw is complicated and expensive, especially in hard metal bodies. However, interchangeable heads particularly typically have a base body made of hard metal. In such systems, the clamping process takes a long time and is also prone to errors.

[0006] Patent document DE 10326928 A1 discloses an interface with a radial clamping system having an eccentric bolt. In such a system, the clamping process is quick and simple, but the system has even more parts and the manufacturing costs are higher. In addition, the eccentric bolt introduces radial forces, which ultimately cause one part of the tool to tilt relative to another part, thereby reducing the clamping accuracy. Summary of the invention

[0007] The object of the present invention is to provide a tool component, a tool pair and a tool which do not have the above-mentioned defects.

[0008] The above object is achieved by providing the technical teaching of the present invention, especially the teachings in the independent claims and the dependent claims and the embodiments disclosed in the specification.

[0009] Specifically, in order to achieve the above-mentioned purpose, the present invention proposes a tool component, which is configured to be connected to a tool pair accessory, wherein the tool component has a centering portion and an axial stop. The tool component also has a plug portion, which is configured to cooperate with a matching plug portion of the tool pair accessory to connect the tool component to the tool pair accessory. By means of the plug portion, a simple, small (especially short), functionally reliable and very accurate positioning method of the tool component relative to the tool pair accessory is created, so that the tool component is firmly and stably connected to the tool pair accessory. In particular, no additional components are required, the production cost of the plug portion is low, and only a small amount of work is involved.

[0010] The tool component is, in particular, a first part of a connection or interface of the tool, the second part of which is the corresponding tool counter-part to which the tool component is intended to be connected. The tool can, in particular, have a tool component and a tool counter-part, and according to one embodiment, the tool can also consist of a tool component and a tool counter-part; however, the tool can also have more components, wherein the tool can, in particular, have a plurality of such interfaces or connections.

[0011] The tool component can be in particular a tool head or a processing head. The tool counter-part can be in particular a holder, which can be directly part of the machine tool or can be introduced into the machine tool and fixed thereto. However, the tool counter-part can also be an extension piece, an intermediate piece, etc. The tool component can also be an extension piece or an intermediate piece, etc. In particular, the tool component and the tool counter-part can be designed as an extension piece or an intermediate piece, which can then in turn be connected in particular to another extension piece or an intermediate piece, or a tool head or a processing head, or a holder.

[0012] In particular, the tap portion is configured to cooperate with a counter tap portion of the tool counter-fitting in order to securely connect the tool component to the tool counter-fitting, in particular in the direction of a longitudinal axis of the tool component and / or the tool.

[0013] In particular, the tap portion of the tool component and the mating tap portion of the tool counter-part preferably jointly form a tap mechanism.

[0014] Such a plug mechanism is defined in particular in that the components connected via the mechanism are first connected to one another by an axial plugging movement and then fixed to one another by a rotational movement. In this case, the plugging path covered during the plugging movement is preferably longer, in particular much longer, than the axial path (also referred to as rotational path) from the initial intervention of the parts to be rotated relative to one another until the parts axially abut one another during the rotational movement of the plug mechanism.

[0015] In order to fasten the tool insert to the tool counter-part by means of a tapping mechanism, the tool insert is first displaced in an axial direction relative to the tool counter-part in a plugging movement, in particular without a rotational movement, and then rotated relative to the tool counter-part in order to produce a firm and stable connection.

[0016] The plug part is particularly configured to match the mating plug part so that the axial movement caused by the rotational movement after the plug movement occurs in the same direction as the previous plug movement. During the rotational movement of the plug part connecting the tool part to the tool counter-part, the tool part is particularly pulled towards the tool counter-part. In this case, the tool part is particularly displaced in the direction of the tool counter-part.

[0017] According to a preferred embodiment, the tap mechanism is configured as a bayonet mechanism.

[0018] The longitudinal axis of a tool component, a tool counter-assembly and / or a tool is in particular the axis extending along the longest extension of the corresponding component and / or the axis defining the axis of symmetry of the corresponding component and / or the axis corresponding to the intended axis of rotation of the corresponding component during machining of a workpiece. The axial direction extends along the longitudinal axis; the radial direction is perpendicular to the longitudinal axis; the circumferential direction extends in particular concentrically around the longitudinal axis.

[0019] The plugging movement of the tap mechanism occurs in particular in the direction of the longitudinal axis, ie in the axial direction; the rotational movement of the tap mechanism occurs in particular in the circumferential direction, ie around the longitudinal axis.

[0020] The centering portion is configured, in particular, to center the tool insert relative to the tool counter-assembly in a radial direction, ie perpendicularly to the longitudinal axis.

[0021] In particular, the axial stop is configured to determine the axial position of the tool insert, ie the position of the tool insert relative to the tool counter-fitting in the direction of the longitudinal axis, when the tool insert is connected to the tool counter-fitting.

[0022] According to an improved solution of the present invention, the tap part has at least one clamping ramp extending along a spiral section line. This represents a particularly simple, short and easy-to-manufacture tap part design. The spiral section line should be understood in particular as a line extending along a portion of the spiral line around the longitudinal axis, in particular up to 180°, preferably less than 180°. Therefore, unlike a thread, there is no need to section the thread line completely around the longitudinal axis, in particular around a full number of circles. The clamping ramp is particularly configured so that when the tool component is connected to the tool counter-part, in particular during the rotational movement of the tap mechanism, the clamping protrusion of the tool counter-part can slide or glide on the clamping ramp. Since the clamping ramp extends along the spiral section line, an axial relative movement between the tool component and the tool counter-part is simultaneously caused during the rotational movement, in particular so that they are clamped to each other.

[0023] In particular, the at least one clamping ramp realizes a clamping wedge which, together with the clamping projection of the tool counter-fitting, realizes a wedge-shaped drive in order to pull the tool element toward the tool counter-fitting with great force during clamping, in particular during a rotational movement of the tap.

[0024] According to an improved solution of the invention, the tap part has two clamping ramps. In this way, a particularly effective clamping with the tool pair accessory can be achieved. Preferably, the two clamping ramps each extend along an associated spiral section line. The two clamping ramps are preferably offset relative to each other in the circumferential direction on the tap part, preferably offset relative to each other by 180° or at least approximately 180°.

[0025] Preferably, the two clamping ramps are arranged at the same axial height or at the same axial position as one another on the tap part, especially with respect to equivalent points on the clamping ramps. In particular, the starting point and the end point of the clamping ramps are preferably arranged at the same axial height as one another. In this way, tilting of the tool component when clamped to the tool counter-part is advantageously avoided; in particular, the introduction of transverse forces transverse to the longitudinal axis when the tool component is rotated relative to the tool counter-part is avoided.

[0026] Alternatively or additionally, it is preferably provided that the two clamping ramps have the same gradient.

[0027] Particularly preferably, the two clamping ramps are designed identically to one another.

[0028] The gradient of at least one clamping ramp, preferably of both clamping ramps, is preferably selected such that a self-locking is established in the region of at least one clamping ramp in the tap mechanism. Particularly preferably, a self-locking is established between at least one clamping projection of the tool counter-fitting and at least one clamping ramp of the tool component. In this way, a particularly effective fixing of the tool component to the tool counter-fitting is advantageously achieved.

[0029] The gradient of at least one clamping ramp, preferably of both clamping ramps, is preferably approximately 15°, preferably 15°, in particular when pairing steel with steel.

[0030] Preferably, each of the two clamping ramps is configured to cooperate with a respective clamping projection of a tool counter-part, wherein the latter preferably has two clamping projections respectively.

[0031] According to an improved solution of the invention, at least one clamping ramp, preferably each clamping ramp, preferably extends at least 90° to at most 180°, preferably at least 95° to at most 120° around the longitudinal axis of the tap. Thus, in order to clamp the tool component to the tool counter-part, only a relatively small rotational movement around a relatively small angular range is required. At the same time, a strong clamping is achieved.

[0032] According to an improved solution of the present invention, the tap portion has at least one insertion surface, which is configured to cooperate with the matching insertion surface of the tool counter-part to allow the tool component to be inserted into the tool counter-part only in at least one specific angular position around the longitudinal axis. In this case, the insertion surface and the matching insertion surface cooperate with each other to define the engagement position for connecting the tool component to the tool counter-part. Particularly preferably, they allow the tool component to be inserted into the tool counter-part in at most one specific angular position or at most two, especially equivalent, angular positions offset by 180° from each other.

[0033] Preferably, the tap has two insertion surfaces, which are correspondingly configured to cooperate with two mating insertion surfaces of the tool counter-part. In this case, the two insertion surfaces are preferably at least substantially oriented parallel to each other, preferably oriented parallel to each other and / or arranged or configured on the tap relative to each other transversely to the longitudinal direction.

[0034] Preferably, at least one insertion surface is designed as a plane. In particular, at least one insertion surface preferably forms an angle with the longitudinal axis which deviates only slightly from 0° at most, in particular at most 5°, preferably at most 4°, preferably at most 2°, preferably at most 1°, preferably at most 0.5°. The angle is particularly preferably 0°, i.e. the longitudinal direction lies in the insertion surface or the insertion surface extends in the longitudinal direction.

[0035] The at least one counter-insertion surface of the tool counter-part is preferably configured to be complementary to the at least one insertion surface.

[0036] According to an improved solution of the present invention, the plug portion is adjacent to the centering portion in the axial direction. Accordingly, in this embodiment, a functional separation is provided between the centering portion on one side and the plug portion on the other side. Therefore, both the centering function of the centering portion and the fastening function of the plug portion can be optimized. Preferably, the plug portion is configured as a clamping protrusion of the tool component, and the clamping protrusion extends in particular from the centering portion in the axial direction (towards the direction of the tool accessory in the installed state).

[0037] According to an improved solution of the present invention, the centering portion has an outer cone or is configured as an outer cone, in particular a conical protrusion, in particular a short cone. This allows the tool component to be particularly well centered at the tool counter-part, in particular when the centering portion of the tool component configured as an outer cone cooperates with the matching centering portion of the tool counter-part configured as an inner cone.

[0038] Alternatively or additionally, the axial stop is preferably designed as an axial annular surface, in particular as an annular surface, the normal vector of which points at least substantially in the longitudinal direction, preferably exactly in the longitudinal direction, or at most at a small angle to the longitudinal direction, at most a few degrees, in particular at most 5°, preferably at most 4°, preferably at most 3°, preferably at most 2°, preferably at most 1°, preferably at most 0.5°. Preferably, the axial annular surface is centered, in particular along a closed circumferential line, in particular in an annular form.

[0039] In particular, the centering portion and the axial stop are preferably jointly configured as a short cone interface with a flat abutment, in particular, the embodiment shown in patent document DE 10048910A1 can be referred to.

[0040] According to an improved solution of the present invention, the tool component part has a processing portion with at least one cutting edge. In this embodiment, the tool component is advantageously configured as a tool head, in particular as an interchangeable head. At least one cutting edge is preferably a geometrically defined cutting edge. In a preferred embodiment, at least one cutting edge can be arranged on the tool component in a single-piece, in particular using the same material, or in a multi-piece, in particular as an embedded cutting edge, a bonded cutting edge or a welded cutting edge or as an interchangeable cutting edge.

[0041] In particular, the tool insert can be designed as a milling head, preferably made of solid carbide, or as a milling head with welded cutting edges, or as a drill, reamer or reaming tool.

[0042] The processing part is preferably arranged axially adjacent to the centering part and opposite to the plug part. In particular, the processing part is arranged at the distal end of the tool component expected to face the workpiece, and the plug part is arranged at the proximal end of the tool component expected to face away from the workpiece. The centering part and the axial stop are arranged between the distal end and the proximal end.

[0043] The tool insert is preferably provided with a clamping element, in particular a wrench lap, which is used to engage a clamping mechanism, by means of which the tool insert and the tool counter-part can be clamped to each other. The wrench lap can in particular be configured such that an open-end wrench can act thereon.

[0044] In order to achieve the above-mentioned purpose, the present invention also proposes a tool pair accessory, which is configured to be connected to a tool component, in particular to a tool component according to the present invention or a tool component according to one of the above-mentioned embodiments. The tool pair accessory has a matching center portion and a matching axial stop and a matching plug portion, and the matching plug portion is configured to cooperate with the plug portion of the tool component to connect the tool pair accessory to the tool component. With respect to the tool pair accessory, in particular, the advantages described above with respect to the tool component are achieved. The tool pair accessory is particularly preferably constructed as described explicitly or implicitly with respect to at least one feature with respect to the tool component.

[0045] The counter-cock is particularly designed to match the cock so that the axial movement caused by the rotational movement after the plug movement occurs in the same direction as the previous plug movement. During the rotational movement of the cock that connects the tool component to the tool counter-part, the tool component is particularly pulled toward the tool counter-part. In this case, the tool component is particularly displaced in the direction of the tool counter-part.

[0046] According to an improved solution of the present invention, the mating tap portion has at least one clamping protrusion, preferably a clamping cam. The at least one clamping protrusion is configured to cooperate with at least one clamping ramp of the tool component so that when the tool component and the tool counter-part, especially the at least one clamping ramp and the at least one clamping protrusion, rotate relative to each other around the longitudinal axis, especially when the at least one clamping protrusion slides on the at least one clamping ramp, the tool component is displaced toward the tool counter-part, especially pressed against the tool counter-part in the axial direction, especially clamped with the tool counter-part.

[0047] In particular, the counter-cock part preferably has two clamping projections, each of which is preferably configured to cooperate with one of the two clamping ramps preferably provided by the cock part of the tool component. The two clamping projections are preferably diametrically opposed to each other on the tool counter-cock part. In particular, the two clamping projections are preferably arranged at the same axial height on the tool counter-cock part. As described above, this has the advantage that, when the tool component is clamped with the tool counter-cock part, no tilting moment is introduced into the tool component relative to the tool counter-cock part.

[0048] According to an improved solution of the present invention, the centering portion has an inner cone, which is especially configured to cooperate with the outer cone of the centering portion of the tool component to center the tool component relative to the tool matching component. Accordingly, the matching centering portion is especially configured as a conical or truncated cone-shaped recess, into which the centering portion of the tool component can be inserted, and the centering portion is configured as a conical convex portion or a conical protrusion.

[0049] Preferably, the counter-centering portion configured as an inner cone is more elastic, i.e. has a stronger elastic deformation capability, than the counter-centering portion configured as an outer cone, so that when the tool component and the tool counter-part are clamped by the outer cone of the counter-centering portion, the inner cone of the counter-centering portion is deformed, in particular widened. In the mutual cooperation of the axial stop and the counter-axial stop, in particular an overdetermination is achieved, so that the tool component can be fixed in place very firmly, stably and reliably relative to the tool counter-part.

[0050] The mating axial stop is preferably configured as a mating axial annular surface, i.e. an annular surface, the normal vector of which is preferably parallel to the longitudinal direction or at most at a small angle to the longitudinal direction, at most a few degrees, in particular at most 5°, preferably at most 4°, preferably at most 3°. Preferably at most 2°, preferably at most 1°, preferably at most 0.5°. Preferably, the mating axial annular surface is in particular along a closed circumferential line, in particular in the form of an annular ring, to the inner cone of the mating middle.

[0051] In the clamped state, the axial ring surface of the axial stop preferably abuts against the matching axial ring surface of the counter axial stop, in particular these surfaces preferably abut against each other over their entire surface. In this way, in particular the overdetermination described above with respect to the inner cone widening of the matching middle is achieved.

[0052] According to a further development of the present invention, the tool counter-assembly has a shank portion or a clamping portion, which is preferably configured to connect the tool counter-assembly to a machine tool, in particular to a spindle of the machine tool.

[0053] The shank of the tool pair accessory preferably has a hollow shank cone interface, in particular for connection to a machine tool spindle.

[0054] In a preferred embodiment, the tool component has a machining part with at least one cutting edge, while the tool counterpart also has a shank part or a clamping part.

[0055] Finally, in order to achieve the above-mentioned object, the present invention also proposes a tool, which comprises at least one tool component according to the present invention or at least one tool component according to one of the above-mentioned embodiments and at least one tool counter-part according to the present invention or at least one tool counter-part according to one of the above-mentioned embodiments, which are preferably connectable to each other, in particular to each other. With regard to the tool, in particular the advantages already explained with regard to the tool component and the tool counter-part are achieved. The tool has in particular an interface or a connection point, which is formed by the tool component and the tool counter-part, in particular in the connection area between the tool component and the tool counter-part.

[0061] Figure 1 A schematic diagram showing an embodiment of a tool component 1, which is configured to be connected to Figure 2 The tool pair accessory 3 embodiment shown. Figure 1 The tool component 1 has a centering portion 5 and an axial stop 7. In addition, the tool component 1 has a plug portion 9, as shown in FIG. Figure 2 As shown, the plug part 9 is configured to cooperate with the matching plug part 11 of the tool counter-part 3 to connect the tool component 1 to the tool counter-part 3. The plug part 9 and the matching plug part 11 especially form a plug mechanism together, preferably a bayonet lock. The specific way of connecting the tool component 1 to the tool counter-part 3 is to first perform a plug movement in the direction of the longitudinal axis L, that is, in the axial direction, and then follow the rotational movement of the tool component 1 torsion relative to the tool counter-part 3, so as to achieve the fixing of the tool component 1 to the tool counter-part 3. In this case, the plug path is longer than the axial displacement path (also called axial rotation path) along the longitudinal direction L, preferably much longer, during the rotational movement, the axial displacement path starts from the initial start of the rotational movement of the plug mechanism until the tool component 1 axially abuts against the tool counter-part 3, and then until the tool component 1 is fixed to the tool counter-part 3.

[0062] In this way, a solution for connecting the tool component 1 to the tool counter-assembly 3 is provided which is very compact, easy to use, saves components, is reliable in function, and is also short in structure in the axial direction.

[0063] The tap part 9 preferably has at least one clamping ramp 13 extending along a spiral section line (around the longitudinal axis L), here two clamping ramps 13. The two clamping ramps 13 are preferably arranged at the same axial position, and their starting point and end point are especially arranged at the same axial height as seen in the direction of the longitudinal axis L. The two clamping ramps 13 are preferably diametrically opposed to each other, especially offset by about 180°, preferably by 180°, in the circumferential direction.

[0064] The clamping ramps 13 preferably each extend in a circumferential direction around the longitudinal axis L over at least 90° to at most 180°, preferably over at least 95° to at most 120°.

[0065] The tap portion 9 preferably adjoins the centering portion 5 in the axial direction, ie in the direction of the longitudinal axis L. In particular, the tap portion 9 is preferably configured as a clamping projection.

[0066] The tap part 9 preferably has at least one insertion surface 15, which is configured to cooperate with a matching insertion surface 17 of the tool counter-part 3, see Figure 2 , to allow the tool component 1 to be inserted into the tool counter-assembly 3 about the longitudinal axis L only in at least one specific angular position, preferably at most one or at most two specific angular positions.

[0067] Preferably, two such insertion surfaces 15 are provided, one at Figure 1 In the figure, only one insertion surface 15 is shown facing the observer. The other insertion surface 15 is preferably constructed or arranged to be diametrically opposed to the tap portion 9 so that it is hidden from the observer.

[0068] Accordingly, the tool counter-part 3 preferably also has two counter-insertion surfaces 17 .

[0069] The centering portion 5 is preferably configured as an outer cone 19. The axial stop 7 is preferably configured as an axial annular surface 21 which surrounds the centering portion 5 along a closed circumferential line.

[0070] Here, the centering portion 5 is in particular designed as a short cone. The axial stop 7 is in particular designed as a flat surface.

[0071] The tool component 1 preferably has a machining portion 23, which in turn preferably has at least one cutting edge 25, in particular at least one geometrically defined cutting edge 25, preferably a plurality of geometrically defined cutting edges 25. The machining portion 23 is arranged opposite to the centering portion 5 and the tap portion 9 adjacent to this, so that when viewed along the longitudinal axis L, the centering portion 5 is arranged between the machining portion 23 and the tap portion 9.

[0072] Here, the tool component 1 is particularly configured as a processing head, particularly preferably as a milling head. The cutting edge 25 can be configured as a welded cutting edge, an inlay cutting edge, or can also be configured as a single piece with the processing portion 23, especially using the same material as the processing portion 23. The tool component 1 can also be configured as a drill, a reamer or a reaming tool or configured in some other suitable manner.

[0073] Figure 2 The figures show an embodiment of a tool pair accessory 3. In the figures, identical elements with identical functions are provided with identical reference numerals, so that reference is made to the above description.

[0074] Figure 2 Tool counter-attachment 3 is shown partially in section in the region of its connection point with tool insert 1 .

[0075] The tool counter-fitting 3 has in particular a counter-centering portion 27 configured to cooperate with the centering portion 5 and a counter-axial stop 29 configured to cooperate with the axial stop 7. Furthermore, the tool counter-fitting 3 has a counter-cocking portion 11.

[0076] It also has at least one clamping projection 31, which is configured to cooperate with at least one clamping ramp 13 so that when the tool component 1 rotates relative to the tool counter-part 3, especially when the at least one clamping projection 31 slides on the at least one clamping ramp 13, the tool component 1 is pressed against the tool counter-part 3, especially drawn into the tool counter-part 3 and finally clamped with the tool counter-part 3. In the embodiment shown in the figure, two clamping projections 31 are provided, which are especially diametrically opposite to each other.

[0077] Here, the matching center 27 is preferably configured as an inner cone 33 , which is preferably more elastic than the outer cone 19 , so that the inner cone 33 , in particular the wall of the inner cone 33 , widens at least partially when the tap mechanism pulls the outer cone 19 into the inner cone 33 .

[0078] Here, the matching axial stop 29 is particularly configured as a matching axial annular surface 35, which is particularly encircled by the inner cone 33 along a closed circumferential line. In the state where the tool component 1 and the tool counterpart 3 are clamped to each other, the axial annular surface 21 preferably abuts against the matching axial annular surface 35 in all directions and firmly.

[0079] In general, the outer cone 19 and the inner cone 33 together cause the tool assembly 1 to be radially positioned relative to the tool counter-assembly 3, wherein the axial annular surface 21 cooperates with the matching axial annular surface 35 to define the axial relative position between the tool assembly 1 and the tool counter-assembly 3 when the two are clamped together.

[0080] The tool pair accessory 3 also has a shank 37 which is configured to be connected to a machine tool, in particular to a machine tool spindle. The shank 37 preferably has a hollow shank cone 39 .

[0081] Figure 3 Show Figure 2 Detailed view of the tool counter-part 3. In this figure, one of the clamping protrusions 31, one of the counter-insertion surfaces 17, as well as the inner cone 33 and the counter-annular surface 35 can be seen particularly clearly.

[0082] Figure 4 A detailed view of a tool 41 is shown, which has a tool component 1 and a tool counter-part 3 in a connected state. Preferably, the tool 41 consists of the tool component 1 and the tool counter-part 3 .

[0083] The present figure shows only a longitudinal sectional detail of the tool counter-part 3, while the tool component 1 is not shown in section, arranged in the tool counter-part 3 or connected to the tool counter-part 3. In order to clamp the tool component 1 to the tool counter-part 3, the tap part 9 is preferably first axially inserted into the mating tap part 11. The insertion surface 15 and the mating insertion surface 17 cooperate with each other to define the angular position of the axial insertion or insertion around the longitudinal axis L. If the clamping ramp 13 is arranged at the height of the clamping projection 31, the tool component 1 is preferably rotated in the clamping direction relative to the tool counter-part 3 by approximately 90°, preferably slightly more than 90°, wherein the clamping projection 31 slides on the clamping ramp 13 or vice versa, wherein the tool component 1, in particular the outer cone 19, is pulled deeper into the tool counter-part 3, in particular the inner cone 33, in particular until the annular surface 21 abuts against the mating annular surface 35. Inner cone 33 is preferably widened at least in places, in particular slightly, so that an overdetermined result is achieved, so that tool insert 1 can be fixed to tool counter-part 3 with high precision and stability.

[0084] In general, this provides a feasible solution for connecting the tool component 1 to the tool counter-accessory 3 which is low in cost, short in structure, precise and stable, simple to use, and saves components.
