Description

Technical Field

[0001] The present invention relates to a clamping adapter for clamping a component, a mechanical element for clamping a clamping adapter capable of clamping a component, a clamping system for clamping a component to a mechanical element of a processing machine and / or a measuring machine, and a processing machine and / or a measuring machine for processing and / or measuring a component, and a method for clamping a component to a mechanical element of a processing machine and / or a measuring machine or releasing the component from the mechanical element.

Background Art

[0002] From Patent Document 1, for example, the same kind of objects such as a clamping adapter for clamping a component, the same kind of clamping system provided with such a clamping adapter, and a mechanical element for accommodating the clamping adapter are known.

[0003] This clamping adapter for clamping a component, particularly a balancing adapter, i.e., the clamping adapter, is provided in a balancing machine for clamping a balanced component / workpiece such as a milling tool, a tool holder, or a pulley, and includes a housing portion of the clamping adapter, a clamping device accommodated in the housing portion of the clamping adapter and capable of clamping the component, and a first operating element capable of operating the clamping device.

[0004] Furthermore, Patent Document 1 shows a mechanical element, i.e., a drive spindle of a balancing machine in this case, and the drive spindle has a housing portion of the mechanical element, an operating device accommodated in the housing portion of the mechanical element, and a second operating element capable of operating the operating device.

[0005] To clamp the workpiece to be balanced, the balancing adapter is screwed to the housing portion of the mechanical element. Similarly, the first actuating element and the second actuating element are also screwed together. By operating the actuating device with the second actuating element, the first clamping device clamps the part to be balanced via the first actuating element and the connected second actuating element.

[0006] The drawback of this clamping system consisting of a clamping adapter and a mechanical element according to Patent Document 1 is that the clamping adapter that holds the part must already be firmly accommodated (here, screwed) in the mechanical element before clamping the part, or the clamping adapter must be firmly accommodated in the mechanical element even after the part is released from the pressing member in the clamping adapter.

[0007] This also has the disadvantage that the replacement time becomes longer and the degree of automation decreases, that is, in a machining process where parts are replaced and the clamping adapter is accordingly replaced, usually, the replacement of the clamping adapter is required (in the case of Patent Document 1, this is done by releasing the screw connection and then (re)tightening the clamping adapter).

[0008] An improvement is provided by a clamping system consisting of a balancing adapter or a clamping adapter and a mechanical element according to Patent Document 2.

[0009] In this document, the clamping adapter similarly comprises a balancing adapter of a clamping system consisting of a balancing adapter for clamping the part to be balanced and a drive spindle (mechanical element) for accommodating the clamping adapter, a housing portion of the clamping adapter, a clamping device accommodated in the housing portion of the clamping adapter and capable of clamping the part, and a first actuating element capable of operating the clamping device.

[0010] Patent Document 2 shows a mechanical element, that is, also the drive spindle of the balancing machine here, and the drive spindle has a housing part of the mechanical element, an operating device housed in the housing part of the mechanical element, and a second operating element capable of operating the operating device.

[0011] Also in this document, a balancing adapter is screwed to the housing part of the mechanical element in order to clamp the work to be balanced. The first operating element and the second operating element are likewise connected to each other here by the coupling means of a bayonet lock. By operating the operating device by the second operating element, the first clamping device clamps the part to be balanced via the second operating element connected to the first operating element.

[0012] However, in order to enable the more rapid replacement of the balancing adapter or the clamping adapter, in Patent Document 2 it is proposed that the housing of the clamping adapter be implemented by two parts, a base body screwed to the drive spindle or the mechanical element and a replaceable body for clamping the part to be balanced.

[0013] According to Patent Document 2, the replaceable body can be detached and removed from the base body in order to balance other parts and can be exchanged for a corresponding other replaceable body (without releasing the screw connection of the base body) (or vice versa). This enables, in Patent Document 2, a more rapid replacement time and a high degree of automation.

Summary of the Invention

Problems to be Solved by the Invention

[0015] The problem of the present invention is to further improve, particularly to simplify, a clamp adapter or a clamp system known in the prior art, and also to enable simple, accurate, safe and reproducible accommodation and holding of the clamped components, and to enable fast changeover time and high automation.

Means for Solving the Problems

[0016] This problem is solved by a clamp adapter for clamping a component, a mechanical element for clamping a clamp adapter capable of clamping a component, a clamp system for clamping a component to a mechanical element of a processing machine and / or a measuring machine, and a processing machine and / or a measuring machine for processing and / or measuring a component, and a method for clamping a component to a mechanical element of a processing machine and / or a measuring machine or releasing a component from a mechanical element, having the features of the independent claims.

[0017] Advantageous developments of the present invention are the subject matter of the dependent claims and the following description, relating to a clamp adapter for clamping a component, a mechanical element for clamping a clamp adapter capable of clamping a component, a clamp system for clamping a component to a mechanical element of a processing machine and / or a measuring machine, and a processing machine and / or a measuring machine for processing and / or measuring a component, and a method for clamping or releasing a component to / from a mechanical element of a processing machine and / or a measuring machine.

[0018] Terms used as needed, such as up, down, front, back, left or right, shall be construed in accordance with their ordinary meanings unless specifically defined otherwise. Terms such as radial direction and axial direction, when used, shall be construed in relation to the central axis or axis of symmetry of the component / component described in this specification unless specifically defined otherwise.

[0019] The term "substantially", when used, can be construed to mean "to a substantial degree" (in accordance with the interpretation of the Supreme Court). An error from the exact content meant by this term can occur inadvertently (i.e., without functional justification) due to manufacturing tolerances or assembly tolerances.

[0020] The subject matter of the present invention A clamp adapter for clamping a component includes a housing portion of the clamp adapter, a first clamping device housed in the housing portion of the clamp adapter and capable of clamping the component, and a first actuating element capable of actuating the first clamping device.

[0021] Furthermore, the clamp adapter provides that the first actuating element has a clamping functional surface, and through this clamping functional surface, when the second actuating element is actuated, the first actuating element can be coupled to a second actuating element capable of actuating a second clamping device of a mechanical element of a processing machine and / or a measuring machine by the second clamping device, or can be released from the second actuating element.

[0022] Thereby, the first actuating element can be actuated by the second actuating element, and when the second actuating element is actuated, the clamp adapter can also be clamped to the mechanical element or released from the mechanical element.

[0023] A clamp adapter capable of clamping a component, in particular a mechanical element for clamping the clamp adapter, includes a housing portion of the mechanical element, a second clamping device housed in the housing portion of the mechanical element, and here, by the second clamping device, a first actuating element of the first clamping device of the clamp adapter capable of clamping the component can be clamped or released, and a second actuating element capable of actuating the second clamping device.

[0024] Thereby, the first actuating element is actuatable by the second actuating element, and in doing so, when the second actuating element is actuated, the clamping adapter can also be clamped to the machine element or released from the machine element.

[0025] A clamping system for clamping a component to a machine element of a processing machine and / or a measuring machine comprises a clamping adapter, in particular the above-mentioned crank adapter, and a machine element, in particular the above-mentioned machine element.

[0026] The clamping adapter has a housing part of the clamping adapter, a first clamping device accommodated in the housing part of the clamping adapter and capable of clamping a component, and a first actuating element for actuating the first clamping device. The machine element has a housing part of the machine element, a second clamping device accommodated in the housing part of the machine element, and a second actuating element for actuating the second clamping device.

[0027] When the second actuating element is actuated, the first actuating element is connectable to the second actuating element or releasable from the second actuating element when the second actuating element is actuated, so that the component in the clamping adapter and the clamping adapter can be clamped to the machine element or released from the machine element.

[0028] A further clamping system according to the invention for clamping a component to a machine element of a processing machine and / or a measuring machine also comprises a clamping adapter, in particular the above-mentioned clamping adapter, and a machine element, in particular the above-mentioned machine element.

[0029] The clamping adapter has a housing part of the clamping adapter, a first clamping device accommodated in the housing part of the clamping adapter and capable of clamping a component, and a first actuating element for actuating the first clamping device. The machine element has a housing part of the machine element, a second clamping device accommodated in the housing part of the machine element, and a second actuating element for actuating the second clamping device.

[0030] When the second actuating element is actuated, the first actuating element is connectable to the second actuating element by the actuation of the second actuating element so that the first actuating element and the second actuating element are operable, in particular axially displaceable, and thereby the part can be clamped to the clamping adapter by the first clamping device.

[0031] A further clamping system according to the invention for clamping a part to a machine element of a processing and / or measuring machine also comprises a clamping adapter, in particular the above-mentioned clamping adapter, and a machine element, in particular the above-mentioned machine element.

[0032] The clamping adapter has a housing part of the clamping adapter, a first clamping device accommodated in the housing part of the clamping adapter for clamping the part, and a first actuating element for actuating the first clamping device. The machine element has a housing part of the machine element, a second clamping device accommodated in the housing part of the machine element, and a second actuating element for actuating the second clamping device.

[0033] The first actuating element has a clamping functional surface through which the first actuating element can be connected to or released from a second actuating element for actuating the second clamping device by the second clamping device during the actuation of the second actuating element, whereby during the actuation of the second actuating element, the part in the clamping adapter and the clamping adapter can be clamped to or released from the machine element.

[0034] A further clamping system according to the invention for clamping a part to a machine element of a processing machine and / or measuring machine also has a clamping adapter, in particular the above-mentioned clamping adapter, and a machine element, in particular the above-mentioned machine element.

[0035] The clamp adapter has a housing part of the clamp adapter, a first clamping device accommodated in the housing part of the clamp adapter for clamping parts, and a first actuating element for actuating the first clamping device. The machine element has a housing part of the machine element, a second clamping device accommodated in the housing part of the machine element, and a second actuating element for actuating the second clamping device.

[0036] The first actuating element has a clamping functional surface, through which the first actuating element can be coupled to or released from a second actuating element that can actuate the second clamping device when the second actuating element is actuated by the second clamping device. Thereby, when the second actuating element is actuated, the first actuating element and the second actuating element can be actuated, particularly displaced axially, and thereby the parts can be clamped to the clamp adapter by the first clamping device.

[0037] A processing machine for processing parts and / or a measuring machine for measuring parts comprises a clamp adapter, or a machine element, in particular the above-mentioned clamp adapter, or the above-mentioned machine element, and / or a clamping system, in particular the above-mentioned clamping system.

[0038] Therefore, the parts can be clamped to the machine element of the processing machine by the clamp adapter, or the clamping system during processing and / or during measurement.

[0039] According to a method of clamping or releasing a component to a machine element of a processing machine and / or a measuring machine by means of a clamping mechanism, in particular by using a clamping adapter, a machine element, a clamping system, and / or a processing machine and / or a measuring machine, in particular by using the above-mentioned clamping adapter, the above-mentioned machine element, the above-mentioned clamping system, and / or the above-mentioned processing machine and / or measuring machine, when clamping or releasing the component to the clamping adapter by the operation of the clamping mechanism, the clamping adapter itself can also be clamped or released to the machine element of the processing machine by the operation of the clamping mechanism.

[0040] According to a method of clamping or releasing a component to a machine element of a processing machine and / or a measuring machine by means of a clamping mechanism, in particular by using a clamping adapter, a machine element, a clamping system, and / or a processing machine and / or a measuring machine, in particular by using the above clamping adapter, the above machine element, and / or the above processing machine and / or measuring machine, a first clamping device for clamping or releasing the component to an actuable actuating element of the clamping adapter is provided with a second clamping device for clamping or releasing the clamping adapter to an actuable actuating element of the machine element, and the first actuating element and the second actuating element are coupled to each other such that they are actuable, in particular axially displaceable, during the operation of the second actuating element, and at this time, the component can be clamped to the clamping adapter by the first clamping mechanism.

[0041] The subject matter of the present invention lies in the following. That is, two clamping devices, namely, a first clamping device for clamping or releasing a component on a clamping adapter and a second clamping device for clamping or releasing the clamping adapter on a machine element, are connected such that both clamping devices are clamped or released by a single operation / movement during the operation of the second clamping device or the second actuating element via the clamping functional surfaces of the first actuating element of the first clamping device (and the clamping mechanism of the second clamping device).

[0042] Thereby, during this "single" actuation (or of the second actuating element or the second clamping device), both the clamping adapter (on the machine element) and the part (on the clamping adapter) can be clamped or released.

[0043] Therefore, both, namely the part and the clamping adapter, can be released, removed and made removable, or firmly clamped (by this single actuation). No additional separate process steps are necessary for fixing the clamping adapter to the machine element and / or for a firm connection of the fixing element, such as screwing in the prior art.

[0044] Optionally, notwithstanding the above, according to the invention, means can also be provided for further fixing the part being in the process of being released / released or releasable, namely the part to be clamped and the clamping adapter, for example against unintentional dropping or loosening.

[0045] Therefore, for example, as will be described below and optionally, a holding device and / or a locking device attached to the machine element housing / part can, in use, lock and hold the clamping adapter to the housing part of the machine element, and / or screwing can, by its use, screw the clamping adapter to the housing part of the machine element. Regardless of whether the clamping adapter has been released or released by the invention, the clamping adapter can thus be held to the machine element. Also, the part to be clamped and the clamping adapter can be exchanged as a unit without the risk of the part being released from the clamping adapter.

[0046] For example, also, the first pressing member (in the clamping adapter) described later clamps the first actuating element against the housing part (of the clamping adapter).

[0047] When the first pressing member is oriented in the release or the opposite of the release operation / release direction (i.e., when clamping the first clamping device (at the front)), even during the release operation of the present invention or the second actuating element, the first clamping device is further clamped, and it is ensured that the clamped part continues to be clamped / held by the clamping adapter.

[0048] However, when the first pressing member is oriented in the opposite of the clamp or the clamping operation / clamping direction (i.e., when the first pressing member releases the first clamping device), thereby, the clamping operation force (caused by the operation of the second actuating element) can be "distributed" to the clamped part (through the strength of the first pressing member).

[0049] Returning to the present invention, as concisely and clearly expressed in the present invention, one operating operation, i.e., the operation of the second actuating element is sufficient, or the combination (or the reverse separation) of the two actuating elements releases, such as the clamping (or the reverse release) of both the clamping adapter on the mechanical element and the part on the clamping adapter.

[0050] Thereby, the present invention realizes a great advantage, i.e., the processing machine or the measuring machine can be quickly exchanged in only one operating step. Thereby, the degree of automation can be increased. As a result, the present invention enables an efficient and effective processing process.

[0051] Furthermore, such a clamping device or system can be easily and cost-effectively realized, and clamping with safe and accurate positioning is also possible. Thereby, the present invention can also easily and cost-effectively realize the accurate positioning, safe fixation, and reproducible attachment of the clamped part on the processing machine or the measuring machine.

[0052] Dependent subject matter of the present invention The clamping adapter can further provide that the first clamping device has a first collet chuck, and the first collet chuck has, in particular, a first sleeve-shaped base and / or a plurality of first clamping tongues that are circumferentially separated from each other by axial slots, are connected to the first sleeve-shaped base, are radially elastic, and have a first clamping region at the front related to the part to be clamped.

[0053] Also, a rear slot that is axially aligned with the front slot can be arranged within the first sleeve-shaped base.

[0054] The clamping adapter can further provide that the first clamping device has a first collet chuck, and the first collet chuck can be arranged in a circumferentially distributed manner and has a plurality of individual first clamping tongues having a first clamping region at the front related to the part to be clamped. In particular, for example, 4, 5, 6, 7, or 8 first clamping tongues can be provided.

[0055] These can preferably be arranged in a ring-shaped and / or concentric (zentrisch) manner around the first actuating element.

[0056] Furthermore, it can also be provided that the sleeve-shaped base or the individual clamping tongues are held within the housing part of the clamping adapter. This is particularly suitable when the part to be clamped has an HSK interface.

[0057] In other interfaces of the part, it may be necessary to provide a clamping element, such as a clamping sleeve, that is formed in the same or different way instead of the first collet chuck. In that case, the clamping sleeve is arranged at other locations or on the housing element of the clamping adapter.

[0058] In particular, it is preferable when a first clamping claw-shaped portion capable of clamping a component is formed on the first clamping tongue-shaped portion or the clamping region at the front of the first collet chuck.

[0059] The first clamping claw-shaped portion can preferably have a shape coupling element located radially outward, for example a specially formed geometric contour. This is particularly important when the component to be clamped has an HSK interface.

[0060] In this case, at other interfaces of the component, it may be necessary to form the shape coupling element differently, or to adapt and form it differently, and / or to arrange it at a different position, for example radially inward.

[0061] Furthermore, it has been proven to be preferable when the first actuating element is formed in multiple parts by a plurality of, in particular at least two, operable partial elements that can be coupled to each other, in particular screwed together, and in some cases formed as a drawbar.

[0062] Also, the first actuating element, or the actuating partial element, or the drawbar of the first actuating element can be provided to be accommodated in the housing part of the clamping adapter so as to be displaceable relative to and axially with respect to the housing part of the clamping adapter.

[0063] Viewed briefly and specifically, the axial displacement causes clamping or release in the first clamping device depending on the direction.

[0064] Furthermore, the first actuating partial element can have a contact surface that acts as a first guide slot, in particular radially outward, for the first clamping tongue-shaped portion of the first clamping device or the first collet chuck.

[0065] Depending on the geometric design of the first contact surface or the first guide slot, and / or depending on the position of the first contact surface or the first guide slot in the first actuating part element, it can have an impact on clamping (or releasing), both in terms of time and from the perspective of the process / sequence and the clamping force.

[0066] In particular, when the first guide slot or the first contact surface comes into contact with the first clamping tongue of the first collet chuck, it is formed to displace the first collet chuck radially, at least regionally, especially in the first clamping region, so that, especially when the first clamping claw can be locked in a form-fitting manner with the part to be clamped, it is advantageous.

[0067] Also, if necessary, it can be provided that the first guide slot or its first contact surface is provided in the housing part of the clamping adapter. However, when they interact with the first collet chuck or its first clamping tongue piece / first clamping claw, they are provided separately or provided in an adapted manner.

[0068] Furthermore, it is advantageous if the second actuating part element forms a clamping functional surface, especially in the end region, especially in the form of a knob or on the outer surface of the knob. This facilitates or promotes reliable gripping or clamping.

[0069] For example, the formation of another clamping functional surface such as a recess and / or an undercut is also conceivable, as long as it does not prevent the form-fitting clamping with the second actuating element, especially the relevant clamping tongue piece, or clamping claw, or form-fitting element.

[0070] Furthermore, the first actuating element, in particular the second actuating sub-element, has a stopper element, which can come into contact with the housing part of the clamping adapter during the actuation of the first actuating element and, if necessary, can displace the housing part axially, which is preferred. Such a stopper element can in particular be formed, for example, as a flat element and can ensure surface contact as much as possible during contact, in particular with a uniform surface load.

[0071] In particular, within the scope of the first pressing member already described and explained in more detail, it is also preferred to use such a stopper element, for example, as a support for a spring element.

[0072] In particular, a sleeve-shaped centering element, which is received in the receiving opening of the housing part of the clamping adapter, can be provided as a first centering element for centrally receiving the part to be clamped, in particular a conical interface, in particular a tool having, for example, a bearing bush, in the clamping adapter.

[0073] Furthermore, it may be preferred to provide a first pressing member, which is the first pressing member already mentioned (and already referred to), in particular has a pressing element, for example, a spring element, and presses the first actuating element against the housing part of the clamping adapter.

[0074] Such a pressing element, or such a spring element, can then be arranged functionally and operationally between the first actuating element and the housing part of the clamping adapter.

[0075] Furthermore, it is particularly advantageous if the first pressing force of the first pressing member is selected depending on the part to be clamped.

[0076] The second clamping device has a second collet chuck, and the second collet chuck has, in particular, a second sleeve-shaped base and / or a plurality of second clamping tongues that are circumferentially separated from each other by axial slots and are connected to the second sleeve-shaped base, and have a front second clamping region associated with a first actuating element that is radially elastic and to be clamped. A mechanical element can be provided.

[0077] A rear slot axially aligned with the front slot can also be arranged within the first sleeve-shaped base.

[0078] However, the second clamping device can also have a second collet chuck, and the second collet chuck has a plurality of individual second clamping tongues that can be arranged in a circumferentially distributed manner and have a front second clamping region associated with a second actuating element to be clamped. A mechanical element can be provided.

[0079] In particular, for example, 4, 5, 6, 7 or 8 second clamping tongues can be provided.

[0080] These can preferably also be arranged in a ring-shaped and / or concentric manner around the second actuating element.

[0081] Furthermore, it is preferable if, in particular, a second clamping claw that can clamp the first actuating element and has a form-fitting element for form-fitting with the clamping functional surface of the first actuating element, for example, having a specially formed geometric contour, is formed within the front second clamping region.

[0082] In that case, it can also be preferable if the second clamping tongue is pressed and held against the second actuating element, in particular, using a clamping element, in particular, an annular spring.

[0083] Furthermore, it is advantageous if the second actuating element is formed in a plurality of parts, in particular by means of a plurality, in particular at least two, actuating sub-elements which can be connected to one another, or joined, in particular screwed together.

[0084] Furthermore, it can be provided that the housing part of the machine element has, as a second guide slot of the second clamping device or of the second clamping tongue of the second collet chuck, in particular a second contact surface on the radially inner side, for guiding the second clamping tongue of the second clamping device or of the second collet chuck.

[0085] Also in this case, it is possible to influence the clamping (or release) both temporally and from the point of view of the process / sequence and the clamping force, by means of the geometry of the second contact surface or of the second guide slot and / or by means of the position at which the second contact surface or the second guide slot is attached to the first actuating sub-element.

[0086] In this case, the second guide slot or the second contact surface is formed such that, when contacting the second clamping tongue of the second collet chuck, in particular in the second clamping region, it displaces the second clamping tongue radially at least in part, so that, in particular, the second clamping jaw can assume a form-fitting engagement with the clamping functional surface of the first actuating element, which is particularly advantageous.

[0087] It is also possible to provide the guide slot or its second contact surface on the second actuating element, if required. However, if these contact surfaces interact with the second collet chuck or its second clamping tongue / second clamping jaw, these contact surfaces have to be provided or adapted separately, correspondingly.

[0088] Furthermore, it is advantageous if the second actuating element is accommodated in the housing part of the machine element so as to be axially displaceable relative to the housing part of the machine element.

[0089] Put simply, the axial displacement causes clamping or release in the second clamping device depending on the direction.

[0090] As a further development, the machine element comprises a machine element housing, within which the housing part of the machine element can be accommodated or held, in particular rotatably, using a ball bearing (see the spindle of a lathe), for example.

[0091] Furthermore, a holding device and / or a locking device, or the above-mentioned holding device and / or locking device, is provided, and this holding device and / or locking device can be used to hold the clamping adapter in a locked state within the housing part of the machine element, and / or a screw connection is provided, and this screw connection can be used to screw the clamping adapter onto the housing part of the machine element.

[0092] This holding device and / or locking device is preferably attached to the machine element housing or a partial housing of the machine element.

[0093] Furthermore, it can be provided that the holding device and / or locking device is mechanically operable and can be locked and held to the housing part of the machine element by form-fitting, in particular during the operation of the clamping adapter.

[0094] Furthermore, a centering element, i.e., a second centering element, can also be provided on the machine element. A second centering element is provided for the centered accommodation of the clamping adapter on the machine element, and this second centering element is considered suitable, in particular, when it is a ball cage accommodated in the accommodation opening of the housing part of the machine element.

[0095] As a further development, it is possible to provide a second pressing member which acts in the same way as, or in opposition to, the first pressing member in particular. The second pressing member has a pressing element, in particular a spring element, for example a compression spring, which presses the second actuating element, in particular its second actuating sub-element, against a partial housing of the mechanical element.

[0096] This second pressing member can preferably have a pressing element, in particular a spring element, which is functionally and operationally arranged between the second actuating element, in particular its second actuating sub-element, and the housing part of the mechanical element.

[0097] Furthermore, it is also suitable if the first pressing force of the first pressing member and the second pressing force of the second pressing member are adjusted to each other, in particular taking into account the parts which apply the pressing force.

[0098] In this case, the first pressing force of the first pressing member and the second pressing force of the second pressing member can be formed to act in the same direction. Alternatively, the first pressing force of the first pressing member and the second pressing force of the second pressing member can be formed to act so as to cancel each other out.

[0099] Furthermore, it is also possible to provide a device which is accommodated in the housing part of the mechanical element and is drivable, in particular pneumatically, or hydraulically, or mechanically, by means of which the second actuating element is displaceable for clamping and / or releasing.

[0100] Furthermore, the device can also be provided to displace the second actuating element in a controlled manner.

[0101] It also appears to be particularly advantageous if the second pressing member and the device are configured such that the displacement force of the device, which is applied in particular pneumatically, or hydraulically, or mechanically, acts against the second pressing force and they are adjusted to each other.

[0102] In a further development, it is preferable when, during the operation of the clamping mechanism or during the operation of the second actuating element, the clamping adapter and the parts are sequentially clamped or released.

[0103] Alternatively, it may also be provided that, during the operation of the clamping mechanism or during the operation of the second actuating element, the clamping or releasing of the clamping adapter and the parts is carried out simultaneously.

[0104] Such a time sequence can in particular be realized or changed by the corresponding arrangement of the first and second slots (for example the axial distance) or by the axial length of the actuating element / actuating partial element.

[0105] Advantageously, a development provides that, during the operation of the clamping mechanism or during the operation of the second actuating element, in particular by the use of certain or the first pressing member (see above), the release of the parts clamped to the clamping adapter is prevented, or that, in particular by the use of certain or the above-mentioned holding device and / or locking device (see above), the release of the clamping adapter clamped to the machine element is prevented.

[0106] Furthermore, it can be provided that, during the operation of the clamping mechanism or during the operation of the second actuating element, the parts are displaced axially relative to the housing part of the clamping adapter and / or the clamping adapter is displaced axially relative to the housing part of the machine element.

[0107] Thereby, the automatic "release" of the corresponding parts can be realized or facilitated.

[0108] Method step In a preferred further development, when clamping by means of the operation of the second actuating element, in particular when clamping by means of the relative axial displacement in the pulling-in direction / clamping direction of the machine element relative to the housing part by means of the second actuating element, in the first clamping stage, it is provided that the second clamping device clamps or engages the first actuating element.

[0109] Furthermore, when clamping is performed by the operation of the second actuating element, particularly when clamping is performed by the relative axial displacement in the retraction direction / clamping direction with respect to the housing portion of the mechanical element by the second actuating element, in the second clamping stage following the first clamping stage, the first actuating element clamped by the second clamping device is also axially displaced in the retraction / clamping direction of the second actuating element (in the first clamping stage, the first actuating element was clamped by the second clamping device).

[0110] In this second clamping stage, it is preferable to clamp the clamped part to the clamping adapter by the first clamping device actuated by the first actuating element, and then, by further operation of the second actuating element, particularly by the relative axial displacement of the second actuating element in the retraction / clamping direction with respect to the housing portion of the mechanical element, to clamp the clamping adapter to the mechanical element.

[0111] Particularly when the above-mentioned first pressing of the first clamping device presses the clamped part against the clamping adapter, and when the part to be pressed is already pressed against the clamping adapter, in the second clamping stage where the clamped part is already pre-pressed against the clamping adapter by the first clamping device, it is particularly preferable to clamp the clamping adapter to the mechanical element.

[0112] Clamping of the clamped part to the clamping adapter using the first clamping device is no longer necessary here (because it has already been performed). The clamping force on the part by the operation of the second actuating element further enhances the first pressing member.

[0113] As a further advantageous development, when releasing by actuation of the second actuating element (wherein the first and second actuating elements are initially joined by a clamped second clamping device), in particular when releasing by relative axial displacement in the release direction of the mechanical element of the second actuating element with respect to the housing part, the first and second actuating elements are axially displaced in the release direction, whereby first only the part clamped to the clamping adapter is released (by releasing the first clamping device), or freed (the second clamping device remaining clamped), and then the clamping adapter clamped to the mechanical element is released (by releasing the second clamping device), or freed, is provided.

[0114] However, it may be suitable when releasing by actuation of the second actuating element (wherein the first and second actuating elements are initially joined by a clamped second clamping device), in particular when releasing by relative axial displacement in the release direction of the mechanical element of the second actuating element with respect to the housing part, that the second actuating element is axially displaced in the release direction, whereby the clamping adapter clamped to the mechanical element is released or freed. The release or freeing in the first clamping device can be compensated or prevented by the above-described first pressing member.

[0115] The slots / contact surfaces and the various adjustments of the actuating elements, i.e., in the following cases, or the adjustments inside and / or between these, as well as the possibility of forming the first clamping device in the clamping adapter (see also the direction of action of the first clamping device in the clamping adapter), enable a number of different clamping sequences and release sequences with appropriate clamping or release stages.

[0116] The processing machine or measuring machine can be, for example, a machine tool such as a milling machine, a grinding machine, or a lathe, a balancing device, a measuring device, a presetting device, or a device for manufacturing and / or shaping and / or measuring the clamped part.

[0117] This provides a clamping adapter for clamping a component, or a mechanical element for clamping a clamping adapter capable of clamping a component, or a clamping system for clamping a component to a mechanical element of a processing machine and / or a measuring machine, and also leads to a method for clamping a component to a mechanical element of a processing machine and / or a measuring machine.

[0118] In that case, it is considered particularly advantageous if the clamping adapter is a balancing adapter or a measuring adapter, or if the component to be clamped is a tool (in the sense of a whole tool consisting of a sharp conical tool holder and a tool body), or if it is a workpiece to be machined particularly by a processing machine or a measuring machine.

[0119] The advantageous embodiments of the present invention described so far include a number of features, which are partially and in some cases integrated and reproduced in the individual dependent claims. However, these features can be suitably considered individually and also integrated into more meaningful combinations.

[0121] The above-described characteristics, features, advantages of the present invention, and the manner in which they are achieved will become clearer and more understandable in relation to the following description of the embodiments of the present invention, which will be described in more detail in connection with the drawings (in the drawings, the same parts / components and functions are assigned the same reference numerals, and for clarity, not all are shown in all the figures as necessary).

Embodiments for Carrying Out the Invention

[0124] General-purpose clamp adapter, or balancing adapter (Figs. 1 to 3 (first embodiment), and Figs. 4 to 5 (second embodiment)) Figs. 1 to 3 and Figs. 4 to 5 each show a first or second balancing adapter 1, which is housed and mounted in a balancing machine spindle 8 of a balancing device 60 and has a tool holder 2 (having an HSK interface 22) held by the balancing adapter 1.

[0125] The illustrated balancing adapter 1 is conceived for clamping a rotating part 2, i.e., the illustrated tool holder 2 having an HSK interface 22 in the present embodiment, to the balancing machine spindle 8 of a balancing machine 60.

[0126] In such a machine, it is particularly important that the part 2 to be measured or balanced is held centered with high concentricity and reproducibility, as well as position accuracy and position reliability. It is also necessary to be able to shorten the setup time as much as possible.

[0127] In the case of the present embodiment, the part 2 is a tool holder 2 (having an HSK interface 22), but it may also be another tool holder for a drill tool, a milling tool, or a grinding tool, a rotor, or other machine parts to be balanced or measured.

[0128] The balancing adapter 1 and the machine element 8 holding it, i.e., the machine spindle 8, are collectively referred to as a clamping system, and by using both together, it is ensured that the part to be clamped 2, in the present embodiment, the tool holder 2 is clamped to the balancing machine 60.

[0129] Clamping system (1, 8) comprising a balancing adapter 1 and a balancing machine spindle 8 (first embodiment, FIGS. 1 - 3) As shown in FIGS. 1 - 3, the balancing adapter 1 includes a housing portion 5 of the balancing adapter that can be inserted into the balancing machine spindle / drive spindle 8 of the balancing device 60.

[0130] Clamping of the part (by the first clamping device 3) The housing portion 5 of this balancing adapter is basically a hollow cylinder, with a receiving opening 45 provided at its upper end and a cylindrical passage 46 extending to its lower end.

[0131] The receiving opening 45 provides a cylindrical receiving area for the conical shank 22 (HSK interface 22 in this embodiment) of the tool holder 2 to be clamped, or generally for the part 2 hereinafter.

[0132] The shank 22 of the part 2 to be clamped is formed in a conical shape and can have a polygonal, circular or other suitable cross-section. Axially above the shank 22, the part 2 to be clamped has a support flange 50 which clamps onto the upper end face of the housing part 5 of the balancing adapter when the part 2 to be clamped is inserted into the receiving opening 45 (whereby the part 2 to be clamped reaches the maximum sinking depth within the receiving opening 45 of the balancing adapter 1).

[0133] In the end region of the conical shank 22 of the part 2, a substantially cylindrical inner axial recess 52 having an inner clamping part 53 is provided, through which the part 2 can be clamped or held by the balancing adapter 1 (in form-fitting by the first clamping device 3 of the balancing adapter 1).

[0134] The bearing bush 21 is inserted into the cylindrical receiving opening 45 of the housing part 5 of the balancing adapter, and in the upper region of the bearing bush 21, a radially elastic tongue is provided.

[0135] The inner contour of the bearing bush 21 conforms to the cross-section of the shank 22 of the part 2 to be clamped such that when the part 2 to be clamped is inserted into the balancing adapter 1 to the maximum sinking depth, the tongue is slightly pushed radially outwards, thereby facilitating or ensuring the centering insertion of the part 2.

[0136] Furthermore, a certain type, or a first clamping device 3, is accommodated in the housing portion 5 of the balancing adapter, and the clamping device 3 consists of a first collet chuck 10 and a first actuating element 4. The first actuating element 4 is for actuating the collet chuck 10 (by an axial displacement of the first actuating element 4 in the release direction 63 or the clamping direction 64), is coaxial with the collet chuck 10, and consists of two parts.

[0137] The first actuating element 4 has an upper first pull rod 15 and a lower second pull rod 16 which is coaxial with the first pull rod 15 and can be screwed onto the first pull rod 15 and is guided in the housing portion 5 of the balancing adapter. Through the second pull rod 16, the first actuating element 4 (as a whole) can be axially displaced and guided within the housing portion 5 of the balancing adapter, and the first clamping device 3 can be actuated (i.e., clamped and released).

[0138] The first collet chuck 10 has a plurality of individual first clamping tongues 11, which are arranged in a ring shape and concentrically around the first actuating element 4 or the first pull rod 15 in the circumferential direction. The lower end of each clamping tongue 11 is located in an annular recess 54 within a cylindrical passage 46, and its upper region has a first clamping region 12 at the front / upper part related to the part 2 to be clamped.

[0139] In the front / upper first clamping region 12 of the first clamping tongue 11, a first clamping claw 13 capable of clamping the part 2 is formed in the form of a radially outer form-locking element 14, and the first clamping claw 13 engages with (is engageable with) the inner clamping portion 53 of the conical shank end (22) of the part 2 during the clamping of the part 2.

[0140] The movement that induces / controls the clamping and release of the first clamping claw portion 13 or the first clamping tongue portion 11 is performed by the radially outer contact surface 19 on the upper first pull rod 15 that acts as the first guide slot 18 for the first clamping tongue portion 11. That is, due to the axial displacement of the first actuating element 4 or the upper first pull rod 15, the first contact surface 19 guides the first clamping tongue portion 11, thereby causing the clamping operation and release operation of the first clamping tongue portion 11.

[0141] As shown in FIGS. 1 to 3, the first guide slot 18 or the first contact surface 19 is formed to displace them radially at least in a partial region, here in the front / upper first clamping region 12, when contacting the first clamping tongue portion 11 of the first collet chuck 10, thereby enabling the first clamping claw portion 13 to be in form-fitting connection with the clamped part 2.

[0142] The lower second pull rod 16 has a knob 6 at its lower end, and the knob 6 provides a clamping functional surface 6 on its outer side for the second clamping device 7 or the second clamping tongue portion 28 related thereto.

[0143] Furthermore, a support element 20 formed as a flange 20 is formed approximately in the center of the lower second pull rod 16, and this support element 20 is guided in a recess 55 that extends in diameter to the lower end of the housing portion 5 of the balancing adapter in the lower region of the cylindrical passage 46 of the housing portion 5 of the balancing adapter.

[0144] A perforated disc 56 is attached to the lower end of the housing portion 5 of the balancing adapter, and the perforated disc 56 has a central recess, and through the central recess, the lower pull rod 16 protrudes from the lower side of the housing portion 5 of the balancing adapter.

[0145] The upper end of the diameter expansion portion 55 in the cylindrical passage 46 of the housing portion 5 of the balancing adapter and the perforated disk 56 limit the possible maximum axial displacement of the support element 20 in this way. Thereby, at the same time, the possible maximum axial displacement of the lower second pull rod 16 or the first actuating element 4 is also limited.

[0146] A spring element 24 is inserted into the diameter expansion portion 55 of the cylindrical passage 46 between the support element 20 and the perforated disk 56. The upper end of this spring element 24 is supported by the support element 20 and the lower end is supported by the perforated disk 56 (see the first pressing member 23 above).

[0147] Therefore, due to the spring force of the spring element 24, the first actuating element 4 is pressed into the release position of the first clamping device 3 via the support element 20 and the lower second pull rod 16 (in this release position, the first clamping claw portion 13 of the first collet chuck 10 is not engaged with the clamped part 2, and therefore, the part 2 is released).

[0148] Clamping of the balancing adapter (by the second clamping device 7) The balancing machine spindle / drive spindle 8 has a housing portion 49 of the (inner) balancing machine element that houses the balancing adapter 1. This housing portion 49 is rotatably mounted in the (outer) drive spindle housing 36 by a ball bearing 37, which is a ball bearing in this case.

[0149] The spindle drive is realized here by a hollow shaft motor 44, which is only schematically shown here.

[0150] This housing portion 49 of the balancing machine element is also basically hollow cylindrical, has a cylindrical receiving opening 47 at the upper end for the balancing adapter 1 or the housing portion 5 of the balancing adapter, and has a cylindrical passage 48 that extends to the lower end.

[0151] The housing portion 5 of the balancing adapter is also basically cylindrical in its outer periphery and has a support flange 51, similar to the clamped component 2. Therefore, the balancing adapter 1 can be inserted into the receiving opening 47 of the housing portion 49 of the balancing machine element until its support flange 51 abuts against the front surface of the housing portion 49 of the balancing machine element.

[0152] A ball bush 39 that holds the balancing adapter 1 at the center is accommodated within the receiving opening 47 of the housing portion 49 of the balancing machine element. The rolling elements of the ball bush 39 can be placed under a radial preload, thereby achieving a non-play centering.

[0153] Furthermore, a second clamping device 7 is accommodated in the housing portion 49 of the balancing machine element, and the second clamping device 7 consists of a second collet chuck 27 and a second actuating element 9 that is coaxial with the second collet chuck 27 for actuating the second collet chuck 27 (by the axial displacement of the second actuating element 9).

[0154] The second actuating element 9 is formed as a compact pulling body 33 that is guided within the housing portion 49 of the balancing machine element. The centering of this pulling body within the housing portion 49 of the balancing machine element is also achieved by the ball bush 39. The rolling elements of this ball bush can ensure a non-play guide under a radial preload.

[0155] The second collet chuck 27 also has a plurality of individual second clamping tongue portions 28 that are arranged in a ring shape and concentrically around the second actuating element 9. The second clamping tongue portions are pressed against the pulling body 33 by the annular spring 25 at their lower ends.

[0156] Each clamping tongue portion 28 has its lower end located in the annular recess 26 of the pulling body 33 / the second actuating element 9, and in its upper region, it has a second clamping region 29 of the clamped component 2, i.e., the balancing adapter 1 or the front / upper part related to the cylindrical passage 46 inside it.

[0157] In the front / upper second clamping region 29 of the second clamping tongue portion 28, a second clamping claw portion 30 that can be clamped to the balancing adapter 1 is formed in the form of a radially inner shape - coupling element 31. During clamping, it can grip the knob 6 at the lower end of the lower second pulling rod 16.

[0158] The actuation that induces / controls the clamping and release of the second clamping claw portion 30 or the second clamping tongue portion 28 occurs by means of a radially inner second contact surface 35 that functions as a second guide slot 34 for the second clamping tongue portion 28 inside the cylindrical passage 48 within the housing portion 49 of the balancing machine element. That is, by axially displacing the second actuating element 9 or the pulling body 33, the second contact surface 35 guides the second clamping tongue portion 28, thereby causing the clamping operation and release operation of the second clamping tongue portion 28.

[0159] As shown in FIGS. 1 - 3, the second guide slot 34 or the second contact surface 35 is formed such that, at least in a region, when in contact with the second clamping tongue portion 28 of the second collet chuck 27, in this case, in the front / upper second clamping region 29, the second clamping tongue portion 28 is displaced radially. Thereby, the second clamping claw portion 30 can be in a shape - coupling locking state with the knob 6 of the second pulling rod 16 of the first actuating element 4.

[0160] At the lower end of the pulling body 33 of the second actuating element 9, the piston 43 of the pneumatic displacement device 42 is fixed.

[0161] A compression spring 41 is sandwiched between the piston 43 and the housing portion 49 of the balancing machine element. For stable support, the compression spring 41 is inserted into a recognizable blind hole 57 in the housing portion 49 of the balancing machine element and the piston 43.

[0162] By means of these compression springs 41 (the second pressing member 40), the second actuating element 9, and thus the second collet chuck 27 (via the second actuating element 9), is pushed into its clamping position (the position of gripping the knob 6 of the first actuating element 4 or the lower end of the second pull rod 16).

[0163] By displacing the piston 43 against the force of the compression spring 41, the second collet chuck 27 can be "released" (release position) (via the second actuating element 9).

[0164] For this purpose, the piston 43 is sealed via a radial seal (not shown in detail) and is arranged axially displaceably within the housing portion 49 of the balancing machine element, and compressed air (or another pressure fluid) can be applied from below.

[0165] As further shown in FIGS. 1 to 3, a mechanical holding and / or locking device 38 attached to the drive spindle housing 36 is also provided. Under the use of the device 38, the balancing adapter 1 is held in a locked state in the housing portion 49 of the balancing machine element, so that the balancing adapter 1 can be held within the housing portion 49 of the balancing machine element even when the second clamping device 7 is released.

[0166] Operating Method In the following, the operating method of the above-described balancing adapter 1 will be explained (Note: FIG. 1 shows the release position of the balancing adapter 1, FIG. 2 shows the intermediate position of the balancing adapter 1, and FIG. 3 shows the clamping position of the balancing adapter 1).

[0167] For example, by means of a piston 43 actuated by compressed air or another pressure fluid, the second actuating element 9 is pressed upward (in the release position of FIG. 1), and also the first actuating element 4 is pressed upward via the upper end face of the pull body 33 of the second clamping device 7 or the second actuating element 9.

[0168] In the illustrated release position (FIG. 1), the second collet chuck 27 is in the released state, and thus the second clamping region 29 at the front / upper part of the second collet chuck 27 is inclined radially outward, releasing the knob 6 at the lower end of the second pull rod 16 of the first actuating element 4. That is, in this case, the form-fitting engagement between the form-fitting element 31 of the second clamping tongue 28 and the clamping functional surface 6 of the knob 6 at the lower end of the second pull rod 16 of the first actuating element 4 is not carried out.

[0169] The first actuating element 4 is also in the release position when the stopper element 20 of the second pull rod 16 is pressed by a spring force in the stop in the cylindrical passage 46 of the housing part 5 of the balancing adapter (in this case, as shown in FIGS. 1 to 3, the balancing adapter 1 is held in the housing part 49 of the balancing adapter element by the holding and / or locking device 38). Here, for this reason, the first clamping region 12 at the front / upper part of the first collet chuck 10 is inclined radially inward, and it releases the clamped part 2.

[0170] That is, in this case, there is no form-fitting engagement between the first form-fitting element 14 of the first clamping tongue 11 and the inner clamping part 53 of the axially recessed part 52 on the inner side of the cylindrical shape of the balancing adapter 1.

[0171] When the force acting on the piston 43 from below decreases, the second actuating element 9 is pushed down by the compression spring 41 sandwiched between the housing part 49 of the balancing machine element and the piston 43.

[0172] As a result, the front second clamping region 29 of the free front end of the elastic second clamping tongue 28 of the second collet chuck 27 slides along the second guide surface / contact surface 35 or the second slot 34. As a result, the front end of the elastic second clamping tongue 28 is pressed radially inward against the knob 6 of the second pull rod 16 and engages with the knob 6 (FIG. 2).

[0173] The first collet chuck 10 remains open (the first actuating element 4 has not yet been gripped and thus has not been pulled axially downward (from the release position)), and the part 2 to be clamped is still free.

[0174] That is, in this first clamping stage, initially only the second collet chuck 27 is actuated / closed, thereby achieving the coupling of the second actuating element 9 and the first actuating element 4. As a result, when the second actuating element 9 is further displaced axially, the first actuating element 4 can also be displaced (together with the coupled second actuating element 9).

[0175] At this time, the holding device and / or the locking device 38 can also be released (see FIG. 2) (the coupling of the two actuating elements 4, 9 protects the balancing adapter 1 from unintentional dropping).

[0176] As the axial displacement of the second actuating element 9 increases, when the first actuating element 4 is displaced axially downward together with the second actuating element 9, the first collet chuck 10 is also closed (second clamping stage, see FIG. 3).

[0177] That is, in this case, the first clamping tongue 11 of the first collet chuck 10 is guided by the first slot 18 or the first guide surface 19, pressed radially outward, and the first collet chuck 10 grips. The part 2 to be clamped is gripped.

[0178] With further increase in the axial displacement of the two actuating elements 4, 9, the clamped part 2 and the balancing adapter 1 are axially pulled in to the maximum (clamping position) against the forces of the two compression springs 24, 41, and both are thereby held in the clamped state (see Fig. 3).

[0179] By applying pressure to the piston 43, the release process can be carried out in the reverse way, and at the end of the release process, the holding device and / or the locking device 38 can also be locked again (see Fig. 1).

[0180] At that time, the "loosened" or released part 2 can be easily removed. The balancing adapter 1 remains held by the holding device and / or the locking device 38.

[0181] Clamping system (1, 8) comprising a balancing adapter 1 and a balancing machine spindle 8 (second embodiment, Figs. 4 - 5) The balancing adapter 1 according to this second embodiment is basically identical in structure to the above-described first balancing adapter 1 (see Figs. 1 - 3) (the components with the same structure are shown in the figures and are not repeated to avoid duplication).

[0182] The first clamping adapter 1 (see Figs. 1 - 3) is significantly different from the second clamping adapter 1 (see Figs. 4 - 5) in that the first pressing member 23 is formed in the clamping adapter 1. That is, in this embodiment, the first pressing member 23 is formed as a preloading member 23 in the direction opposite to the release or release operation / release operation direction.

[0183] The preloading member 23 preloads the first clamping device 3, so that even when the second actuating element 9 is in the release position, the first clamping device 3 is further clamped, and it can be ensured that the clamped part 2 further maintains the clamped state / holding state on the balancing adapter 1.

[0184] The component 2 and the balancing adapter 1 form, so to speak, a (preloaded) unit and can be exchanged / set up as a unit as a (preloaded) common clamp set.

[0185] For this purpose, as shown in FIGS. 4 to 5, the compression spring 24 (accommodated in the blind hole 57) is inserted between the support element 20 and the housing part 5 of the balancing adapter so that the first actuating element 4 is axially pushed downward from the housing part 5 of the balancing adapter, i.e., so that the first collet chuck 10 is actuated or closed. For this reason, the component 2 already inserted in the balancing adapter 1 is preloaded within the balancing adapter 1.

[0186] Also, unlike the first balancing adapter 1 (see FIGS. 1 to 3), as shown in FIGS. 4 to 5, the balancing adapter 1 does not comprise a holding device and / or a locking device 38 in the present embodiment. The balancing adapter 1 is, in the present embodiment, "solely" / only held by the second clamping device 7 within the housing part 49 of the balancing machine element.

[0187] Operating method In the following, the operating method of the above-described balancing adapter 1 will be explained (Note: FIG. 4 shows the release position of the balancing adapter 1, and FIG. 5 shows the clamp position of the balancing adapter 1).

[0188] For example, also in the present embodiment, the second actuating element 9 is pushed upward by a piston 43 to which compressed air or another pressurized fluid is applied.

[0189] In the illustrated release position (FIG. 4), the second collet chuck 27 is in the released state, and thus, at that time, the second clamping region 29 at the front / upper part of the second collet chuck 27 is inclined radially outward to release the knob 6 at the lower end of the second pull rod 16 of the first actuating element 4.

[0190] That is, in this case, there is no form-fitting engagement between the second form-fitting element 31 of the second clamping tongue 28 and the clamping functional surface 6 of the knob 6 at the lower end of the second pull rod 16 of the first actuating element 4.

[0191] The first actuating element 4 is in the clamping position by the spring force of the first pressing member 23 (preloading member) in this embodiment. Therefore, in that position, the first clamping region 12 at the front / upper part of the first collet chuck 10 is inclined radially outwards, clamping the clamped part 2 to the balancing adapter 1.

[0192] That is, in this embodiment, a form-fitting engagement is performed between the first form-fitting element 14 of the first clamping tongue 11 and the inner clamping part 53 within the axially recessed portion 52 on the inner cylindrical side of the balancing adapter 1.

[0193] The clamped part 2 and the balancing adapter 1 form a preloaded clamping set.

[0194] When the force acting on the piston 43 from below decreases, the second actuating element 9 is pushed down by the compression spring 41 sandwiched between the housing part 49 of the balancing machine element and the piston 43.

[0195] Thereby, the second clamping region 29 at the front of the free front end of the elastic second clamping tongue 28 of the second collet chuck 27 slides along the second guide surface / contact surface 35 or the second slot 34. As a result, the front end of the elastic second clamping tongue 28 is pressed radially inwards against the knob 6 of the second pull rod 16 and engages with the knob 6 (Fig. 5). The coupling between the second actuating element 9 and the first actuating element 4 occurs.

[0196] With a further increase in the axial displacement, at this time, both actuating elements 4, 9 are such that the clamped part 2 and the balancing adapter 1 are pulled in to the maximum (clamping position), thereby holding both in a clamped state (see Fig. 5).

[0197] By applying pressure to the piston, the release process can be carried out in the reverse manner.
