[0121] FIGS. 6a and 6b show schematic graphical representations of a further embodiment of the holding device according to the invention and an interchangeable ring.

[0122] FIG. 1 shows a schematic graphic three-dimensional representation of the holding device 3 according to the invention for positively receiving and holding the interchangeable ring 2 according to the invention as shown in FIG. 2.

[0123] According to this embodiment, the carrier ring 5 is formed from a base plate 24 and a base part 25, which are bolted together. Optionally, the parts of the carrier ring 5 that cannot be moved relative to each other may be manufactured as one part. In the depicted embodiment, several separations are provided to enable assembly.

[0124] Twelve adjusting pins 7 are provided on the base part 25 of the carrier ring 5, projecting in the axial direction on the front face. This forms four attachment regions 22 on the carrier ring 5, wherein the respective attachment regions 22 enclose an angle 23 of 45 with one another.

[0125] Further, four holding cams 4 projecting radially outwards on the circumference are arranged on the interchangeable ring 2.

[0126] When the interchangeable ring 2 is now inserted into the carrier ring 5, the holding cams 4 are arranged in the insertion regions 31, which are located between the adjusting pins 7.

[0127] According to this embodiment, the carrier ring 5 is surrounded by a sleeve ring 6 arranged concentrically to the carrier ring 5. The sleeve ring 6 is positively and rotatably connected to the carrier ring 5. Further, the sleeve ring 6 has four clamping jaws 8 projecting radially inwards on the front face.

[0128] The sleeve ring 6 may have two positions relative to the carrier ring 5.

[0129] In the first position of the sleeve ring 6, the clamping jaws 8 are arranged in the circumferential direction next to the insertion regions 31 of the carrier ring 5. As a result, the interchangeable ring 2 can be removed from the holding device 3 and/or inserted into the holding device 3 without hindrance.

[0130] In the second position of the sleeve ring 6, the clamping jaws 8 are arranged in the circumferential direction at least in sections above the insertion regions 31 of the carrier ring 5. If the interchangeable ring 2 is inserted into the holding device 3, a positive connection is established between the interchangeable ring 2 and the holding device 3 in the second position.

[0131] According to this embodiment, the sleeve ring 6 is designed with slots and comprises a clamping device 15. A clamping force may be applied to the sleeve ring 6 by the clamping device 15, whereby the sleeve ring 6 is compressed and/or contracted.

[0132] The sleeve ring 6 may be slotted in a way that on the one hand a compression of the sleeve ring 6 and on the other hand an extension of the sleeve ring 6 is only possible up to a certain position, the so-called neutral position. This can ensure that in the event of failure of the clamping device 15, the positive connection of the holding device 3 with the interchangeable ring 2 is still present and/or given.

[0133] The design of the carrier ring 5 and the sleeve ring 6 makes it possible to create a positive and frictional connection between the interchangeable ring 2 and the holding device 3.

[0134] According to this embodiment, a first projection 16 with a first, in particular conical, sliding surface 17 is provided on the outer circumference of the carrier ring 5, in particular on the outer circumference of the base part 25, and a second projection 18 with a second, in particular conical, sliding surface 19 is provided on the inner circumference of the sleeve ring 6. Further, the adjusting pins 7 have a recess 20 for forming a weakened bending region.

[0135] The first sliding surface 17 and the second sliding surface 19 are designed to interact with each other. The tensioning of the clamping device 15 causes the second sliding surface 19 to move along the first sliding surface 17, allowing the clamping jaws 8 to move in the direction of the carrier ring 5 and in the direction of the centre of the carrier ring 5. As a result, the clamping jaws 8 may be pressed against the holding cams 4 on the one hand and the sleeve forming the sleeve ring 6 and the adjusting pins 7 may be pressed against the interchangeable ring 2 on the other hand.

[0136] This may create a substantially rigid connection between the interchangeable ring 2 and the holding device 3.

[0137] According to this embodiment, two fixation devices 9 are provided for fixing the sleeve ring 6 in its first position, each comprising a fixation pin 10 with a fixation projection 11.

[0138] The respective fixation device 9 may substantially assume two positions. In the first position of the fixation device 9, the fixation projection 11 engages positively in a recess 12 of the sleeve ring 6, whereby the sleeve ring 6 is held in its first position.

[0139] In the second position of the fixation device 9, the fixation projection 11 is arranged at a distance from the sleeve ring 6, so that the sleeve ring 6 is rotatable relative to the carrier ring 5.

[0140] According to this embodiment, a spring 14 is arranged in a recess 13 of the carrier ring 5, wherein the spring 14 is configured to bring the respective fixation device 9 into its first position. In the first position of the fixation device 9, the fixation pin 10 projects from the carrier ring 5. By inserting the interchangeable ring 2 into the holding device 3, the fixation pins 10 and thus also the springs 14 are compressed, bringing the fixation devices 9 into their second position. In other words, the sleeve ring 6 is freely rotatable relative to the carrier ring 5 as soon as the interchangeable ring 2 is inserted into the holding device 3.

[0141] According to this embodiment, the holding device 3 comprises a rotation device 21 comprising a spring 14, which is arranged in an annular groove of the carrier ring 5. The rotation device 21 is configured to bring the sleeve ring 6 into its second position.

[0142] The spring 14 is in engagement with the sleeve ring 6 and the carrier ring 5. In the first position of the rotation device 21, the spring 14 generates a spring force F1 acting on the sleeve ring 6, whereby the sleeve ring 6 can be brought into its first position. In the second position of the rotation device 21, in which the sleeve ring 6 is in its second position, the spring 14 generates a spring force F2 acting on the sleeve ring 6. This spring force F2 is less than the spring force F1. In other words, the spring 14 is partially released when the sleeve ring 6 is in its second position.

[0143] According to this embodiment, a connection between the interchangeable ring 2 and the carrier ring 5 is established according to the following steps. First, the sleeve ring 6 is brought into its first position, in which the clamping jaws 8 are arranged next to the insertion regions 31. In this position, the fixation projection 11 of the fixation device 9 engages in a recess 12 of the sleeve ring 6, whereby the sleeve ring 6 is fixed in its first position. When the interchangeable ring 2 is inserted, the fixation pins 10 projecting beyond the carrier ring 5 are pressed downwards. As a result, the fixation devices 9 and the fixation projections 11 arranged on them are also moved downwards and the sleeve ring 6 is released. The spring force acting on the sleeve ring 6, generated by the rotation device 21, brings the sleeve ring 6 into its second position immediately after its release. In the second position, the clamping jaws 8 are arranged at least partially over the insertion regions 31, whereby the interchangeable ring 2 is positively engaged with the holding device 3. In this second position of the sleeve ring 6, the interchangeable ring 2 is already positively connected to the holding device 3, which means that unintentional separation can no longer occur.

[0144] This means that only one person is required to create the connection between the interchangeable ring 2 and the holding device 3, as the substantial changes in position of the individual components take place automatically.

[0145] The sleeve ring 6 may then be compressed by actuating the clamping device 15. Among other things, this moves the clamping jaws 8 towards the carrier ring 5 and towards the centre of the carrier ring 5 and presses the adjusting pins 7 towards the centre of the carrier ring 5. This may produce a frictional and positive connection between the holding device 3 and the interchangeable ring 2.

[0146] According to this embodiment, the clamping device 15 has a clamping lever 26, a first clamping part 27, a second clamping part 28, three connection devices 29 and an adjusting device 30. The connection devices 29 are not depicted for better clarity.

[0147] The first clamping part 27 is connected to the sleeve ring 6 via the first connection device 29. The clamping lever 26 is connected to the sleeve ring 6 via the second connection device 29. The second clamping part 28 is connected to the clamping lever 26 via the third connection device 29. According to this embodiment, the first and second clamping parts 27, 28 are connected to each other via the adjusting device 30, whereby the clearance between the two clamping parts 27, 28 can be changed and the clamping force of the clamping device 15 can be adjusted by actuating, in particular rotating, the adjusting device 30.

[0148] According to this embodiment, a securing device 1 is provided on the sleeve ring 6. The securing device 1 is designed to hold, fix and/or secure the clamping lever 26 in its tensioned and/or closed settings, in particular its holding setting.

[0149] The clamping lever 26 has a blocking device, wherein the blocking device may engage in a recess 32 of the carrier ring 5, in particular a recess 32 of the base plate 24, when the sleeve ring 6 is in its second position.

[0150] FIGS. 6a and 6b show schematic graphic representations of a further embodiment of the holding device 3 according to the invention and an interchangeable ring 2 for insertion into this holding device 3. In this embodiment, there is a first contact device 33 in the holding device 3 and a second contact device 34 in the interchangeable ring 2, each in the form of a circular insert. The contact devices 33, 34 have electrical contacts 35, 36 in the form of electrical plug pins and correspondingly designed sockets. The electrical contacts are formed in four orthogonally arranged rows of 4 contacts each.

[0151] This allows an electrical or electronic connection to be created between the first contact device 33 and the second contact device 34 when the interchangeable ring 2 is inserted into the holding device 3.

[0152] This configuration may be provided in all embodiments.

[0153] This exemplary configuration allows the inventive effects to be achieved.

[0154] The invention is not limited to the illustrated embodiments, but includes any holding device 3, any interchangeable ring 2, any arrangement comprising the holding device 3 according to the invention, and any method according to the following claims.
