[0007] The invention relates to an exchange adapter system with a fixed part and with a loose part interchangeably joined to the fixed part, wherein the position of the loose part relative to the fixed part is determined by means of at least two centering sleeve inserts, each in a centering sleeve insert.

[0008] 25 engaging centering and anti-rotation bolts are secured, and each centering sleeve insert has a centering sleeve.

[0009] From DE 102021 118 324 Al is a centering sleeve insert

[0010] 30 known with a longitudinally slotted centering sleeve.

[0011] Confirmation copy The present invention is based on the problem of improving the positioning accuracy of an exchange adapter system when

[0012] To increase the joining of the loose part with the fixed part.

[0013] This problem is solved by the features of the main claim. Each centering sleeve insert has a support spring located in a sleeve receptacle of the loose part or the fixed part, which supports a centering sleeve. Furthermore, a locking device attached to the loose part or the fixed part containing the sleeve receptacle limits the stroke of the centering sleeve in a longitudinal direction of the exchange adapter system.

[0014] The centering sleeve insert has a centering sleeve, a support spring, and a locking mechanism. The support spring sits on the base of the sleeve receptacle. The support spring carries the centering sleeve, which is longitudinally displaceable within the sleeve receptacle. The longitudinal travel of the centering sleeve is limited by the locking mechanism, e.g., a pin. This locking mechanism is attached to the joining part, i.e., the fixed or loose part, that has the sleeve receptacle. The corresponding other joining part, i.e., the loose part or the fixed part, has the centering and anti-rotation pins. When the fixed part is joined to the loose part, the centering and anti-rotation pins engage with the centering sleeves. This causes the centering sleeves to be displaced longitudinally, compressing the support springs. When the joining parts are locked, the relaxing centering sleeve inserts can adapt to the centering and anti-rotation bolts.The centering and anti-rotation bolts are thus firmly seated in the centering sleeve inserts. Further details of the invention will become apparent from the dependent claims and the following description of schematically illustrated embodiments.

[0035] Figures 1-12 show an interchangeable adapter system (10) with accessories and individual parts. Such interchangeable adapter systems (10) are used, for example, on industrial robots to connect different tools or tool systems to them. The interchangeable adapter system (10) has, as connecting parts (20, 80), a fixed part (20) that is connected to the industrial robot and a loose part (80), for example, a tool-carrying part. The tool can be, for example, a cutting or forming tool, a handling tool, etc. At the separable interface (16) between the fixed part (20) and the loose part (80), for example, all media, electrical energy, and / or signals required at the loose part (80) and / or at the tool are transmitted.

[0036] To operate the industrial robot with a different tool, the loose part (80) is exchanged. For this purpose, the industrial robot moves the exchange adapter system (10) so that the loose part (80) is inserted, for example, into a storage station (140). A locking mechanism securing the loose part (80) to the fixed part (20) is then released. When the fixed part (20) is lifted out by the industrial robot, the interface (16) between the fixed part (20) and the loose part (80) is disconnected. Subsequently, the fixed part (20) is moved by the industrial robot to another storage station (140). There, the fixed part (20) is joined with a loose part (80) provided in this storage station (140) and locked together. The newly assembled exchange adapter system (10) can now be moved by the industrial robot according to the specific task.

[0037] In the illustration of Figure 1, the fixed part (20) has a housing (21) with a mounting flange (22) on the top. The fixed part (20) can be attached to the industrial robot, for example, by means of screws, using this mounting flange (22). A centering collar (23) ensures the central position of the fixed part (20) relative to the industrial robot. A plurality of transmitters (24) are arranged on the circumferential surface of the fixed part (20). These transmitters (24) are, for example, media transmitters (25) as well as electrical transmitters (26) for power, data, and signals. Optionally, these transmitters (24), or some of the transmitters (24), can also be arranged inside the fixed part (20).

[0038] The media transmitters (25) on the fixed part (20) have, for example, pneumatic or hydraulic inlets (27). These open into transition outlets (28) located on the joining side (31) of the fixed part (20), see Figure 2. The transition outlets (28) have, for example, sealing rings (29) to ensure a sealed media transfer to the loose part (80). The media transferred by means of these media transmitters (25) are used, for example, to actuate a gripping device, to drive a tool, etc.

[0039] The electrical transmitters (26) for energy, data, and signals are designed for specific applications. For example, a two-pole energy transmitter can be used to transmit drive energy to a tool. The electrical potential is then, for example, a DC voltage of 24 volts or 48 volts. A five-pole data transmitter can be used, for example, to transmit sensor data to a higher-level control system.

[0040] Further media connections (32) are used in the exemplary embodiment for controlling, for example, pneumatic functions in the fixed part (20). These functions can be monitored, for example, by means of sensors. Figure 1 shows the exchange adapter system (10) in a state in which the fixed part (20) and the loose part (80) are spaced apart. An imaginary center line (14) penetrates the fixed part (20) and the loose part (80) in a longitudinal direction (15) of the exchange adapter system (10).

[0041] Three centering and anti-rotation bolts (33) project from the fixed part (20) towards the loose part (80), see Figure 2. Centering sleeve inserts (101) are arranged in the loose part (80), into which the centering and anti-rotation bolts (33) engage when the exchange adapter system (10) is joined. It is also conceivable to arrange the centering and anti-rotation bolts (33) on the loose part side and the centering sleeve inserts (101) on the fixed part side. The loose part (80) and the fixed part (20) are aligned relative to each other by at least two centering and anti-rotation bolts (33) and their associated centering sleeve inserts (101).

[0042] In the embodiment shown, the centering and anti-rotation bolts (33) are arranged unevenly on a common pitch circle. On this pitch circle, the centering angle between the individual centering and anti-rotation bolts (33) is between 117 degrees and 125 degrees. Therefore, the fixed part (20) and the loose part (80) can only be joined relative to each other in a single orientation.

[0043] In the exemplary embodiment, the individual centering and anti-rotation bolts (33) are identical in construction. They are each pressed into the fixed part (20) to a defined depth and secured by means of a threaded washer (34) screwed into the fixed part (20). The portion of the centering and anti-rotation bolts (33) projecting from the joining side (31) has a conical section (35) and a cylindrical section (36) mounted on it. The length of the cylindrical section (36) is, for example, 38% of the projecting length of the centering and anti-rotation bolt (33). The diameter of the cylindrical section (36) is, for example, 70% of its length. In the exemplary embodiment, the tip angle of the conical section (35) is 20 degrees. This angle can be between 15 degrees and 30 degrees.

[0044] At the joining side (31), the fixed part (20) has a locking bolt carrier (37) attached to the fixed part housing (21), with an engagement pin (39). The engagement pin (39) has a cylindrical outer contour. The diameter of this outer contour is, for example, 42% of the outer diameter of the fixed part (20). The longitudinally oriented length (15) of the engagement pin (39) is, for example, 42% of the total length of the fixed part (20).

[0045] The engagement pin (39) is cage-like. A plurality of locking bolts (41) are slidably mounted in the engagement pin (39). In the exemplary embodiment, eight locking bolts (41) project radially from the outer surface of the engagement pin (39) at evenly distributed intervals. They are oriented perpendicular to the center line (14) of the exchange adapter system (10).

[0046] In the exemplary embodiment, all locking bolts (41) are identical. Each individual locking bolt (41) has a circular cross-sectional area. A stroke and rotation limiter (42) is arranged in the fixed part (20) for each individual locking bolt (41), see Figure 3. This limiter, for example, has a guide ball (38) mounted in the locking bolt carrier (37), which engages in a guide groove (43) of the locking bolt (41), see Figures 4-8. Other designs for the stroke and rotation limiter (42) are also conceivable. The locking bolt (41) can also have a square, rectangular, etc., cross-section. In the exemplary embodiment, each individual locking bolt (41) is made of a bearing steel, e.g., 100Cr6 with material number 1.3505.

[0047] Figures 4-7 show two views and two sectional views of a locking bolt (41). The sectional planes are offset from each other by 90 degrees. The individual locking bolt (41) has an actuating end face (44) and an engagement end face (51). In the representations of Figures 1 to 3, the actuating end face (44) lies within the engagement pin (39). The engagement end face (51) protrudes from the engagement pin (39).

[0048] The actuating face (44) is designed as a multiaxially curved surface. In the planes oriented perpendicular to the longitudinal direction (15), the actuating face (44) has a constant radius in each plane. With the locking bolt (41) installed, the centers of these radii are offset from the actuating face (44) in the direction of the center line (14). The radii of curvature in the planes perpendicular to the longitudinal direction (15) increase from the side facing away from the guide groove (43) towards the guide groove (43). The radius of this conically shaped depression is, for example, between 15.3 millimeters and 16.8 millimeters.

[0049] In the radial plane of the exchange adapter system (10) penetrating the locking bolt (41) and in the planes parallel to the radial plane, the curvature is formed as a protrusion. The respective center of the radius is offset towards the engagement face (51) relative to the actuating face (44). In this cross-sectional plane, the actuating face (44) has a control area (47) adjacent to the side of the guide groove (43), a locking area (46), and a securing area (45).

[0050] The locking section (45) forms an angle of, for example, 7.5 degrees with the center line (14) in the radial plane. It is designed as a straight line segment in the radial plane and in the planes parallel thereto. This angle is arranged, for example, such that a wedge is formed at the end facing away from the guide groove (43). The length of the locking section (45) is, for example, 54% of the diameter of the locking bolt (41).

[0051] The locking section (45) transitions seamlessly into the locking section (46). In the locking section (46), the angle between the locking bolt (41) and the center line (14) in the radial plane is between 2 and 5 degrees. In the embodiment shown, this angle is 3.75 degrees. The length of the locking section (46) is, for example, 17% of the diameter of the locking bolt (41).

[0052] In the control area (47), the contour of the locking bolt (41) is arc-shaped in the radial plane and in the planes parallel thereto. This arc can have a constant radius or segmentally defined radii. In the exemplary embodiment, the constant radius of curvature is, for example, approximately half the radius of curvature in the plane normal to the longitudinal direction (15). The center point of this radius is offset from the actuating end face (44) in the direction of the engagement end face (51).

[0053] The intervention face (51) has two wedge surfaces (52, 53).

[0054] These are an engagement wedge surface (52) and a return wedge surface (53). The engagement wedge surface (52) and the return wedge surface (53) are arranged symmetrically about a plane that is oriented normal to the longitudinal direction (15). In the exemplary embodiment, the two wedge surfaces (52, 53) have the same size. The wedge angle enclosed by the two wedge surfaces (52, 53) is, for example, 90 degrees.

[0055] A locking piston (61) is slidably mounted in the locking bolt carrier (37), see Figure 3. The fixed part (20) has a cylindrical piston receptacle (71) for this purpose. The locking piston (61) has a piston disk (62) with a circular cross-section and a locking pin (63). The piston disk (62) has a groove (64) for receiving a piston seal (65). The locking piston is made, for example, of a case-hardening steel, e.g., 16MnCr5 with material number 1.7131.

[0056] The locking pin (63) is located centrally on the piston disk (62) and is oriented towards the loose part (80). It has a cylindrical section (66), a transition section (67), and a frustoconical section (68). In this embodiment, the diameter of the cylindrical section (66) is 44% of the diameter of the piston disk (62). Its length in this embodiment is 71% of the length of the locking pin (63).

[0057] The transition area (67), see Figures 3 and 8, is torus-shaped. Its radius centerline is concentric with the centerline (14) of the exchange adapter system (10) in the locking pin (63). The magnitude of the radius corresponds, for example, to the magnitude of the radius of the control area (47). In the exemplary embodiment, the length of the transition area (67) is 11.5% of the length of the locking pin (63). In the exemplary embodiment, the frustoconical area (68) has an apex angle of 50 degrees. Its base surface (69), oriented perpendicular to the longitudinal direction (15), has, for example, a diameter of 34% of the diameter of the piston disk (62).

[0058] The stroke of the locking piston (61) in the longitudinal direction (15) is greater than the sum of the lengths of the transition area (67) and the frustoconical area (68) of the locking pin (63). In the exemplary embodiment, the stroke is 50% greater than the sum of these lengths. The maximum stroke of the locking piston (61) is less than the length of the cylindrical area (66) of the locking pin (63). The locking piston (61) is displaceable between a first end position and a second end position in the longitudinal direction (15). The first end position is limited by, for example, an integrated housing cover (72) of the fixed housing (21). This first end position is also referred to as the release position. When the locking piston moves from the first end position towards the second end position, the locking bolts (41) are displaced radially outwards. The second end position is, for example,The stroke and rotation limit (42) of the locking bolts (41) is limited. Other stroke limits are also conceivable. This second end position, in which the locking bolts (41) are maximally extended, is hereinafter referred to as the operating end position.

[0059] One or both end positions of the locking piston (61) can be monitored, for example, by means of limit or proximity switches, a magnetic measuring system, etc., in order to enable subsequent functions. If only one end position is monitored, the air-out position, for example, is monitored. In the piston receptacle (71), the locking piston (61) is biased in the direction of the operating end position by means of a spring (73). In this embodiment, this spring (73) is a compression spring (73) that is supported against the housing cover (72) and the locking piston (61). Optionally, the locking piston (61) can also be pneumatically biased in this stroke direction.

[0060] In the direction of the release position, the locking piston (61) is moved against the force of the spring (73) either by means of a medium or electrically controlled mechanism. A medium-controlled actuation for releasing the locking piston (61) can be pneumatic or hydraulic.

[0061] The loose part (80), cf. Figure 9, has a contour congruent to that of the fixed part (20) in a top view along the longitudinal direction (15). It has transfer surfaces (82) on its outer surface (81). These are, for example, designed to be complementary to the transfer surfaces (24) of the fixed part (20). The loose part (80) is bounded in the longitudinal direction (15) by a joining side (83) oriented towards the fixed part (20) and the tool side (84) facing away from the fixed part (20).

[0062] In the exemplary embodiment, the loose part (80) has a through central opening (85). A tool can be attached to the tool side (84), which is centered, for example, by means of a tool adapter inserted into the opening (85).

[0063] The loose part (80) has a loose part housing (86) in which a retaining ring (91) is inserted and fastened. The joining side (83) of the loose part (80) has media inlets (87) which are connected, for example, to media outlets (88) on the outer surface (81). In the illustrations of Figures 1 and 9, the joining side (83) has three sleeve receptacles (89). The position of these sleeve receptacles (89) corresponds to the position of the centering and anti-rotation bolts (33) of the fixed part (20). In the embodiment example, a centering sleeve insert (101) is located in each sleeve receptacle (89). The number of centering sleeve inserts (101) is greater than or equal to the number of centering and anti-rotation bolts (33). All centering sleeve inserts (101) are identical in construction to each other in the exemplary embodiment.

[0064] Figure 10 shows a sectional view of the retaining ring (91). The retaining ring (91) is attached to the loose part housing (86), for example, by means of several fastening screws (92). The retaining ring (91) is a circumferential ring with an outer support ring (93) and an inner locking ring (94). The locking ring (94) projects from the support ring (93) in the direction of the joining side (83). The locking ring (94) has an insertion surface (95) pointing towards the joining side (83) and a retaining surface (96) facing away from the joining side (83). The insertion surface (95) and the retaining surface (96) define a retaining wedge (97) pointing towards the center line (14). The inner circle of the retaining wedge (97) has a diameter larger than the outer diameter of the engagement pin (39) when the locking bolts (41) are retracted. The transition between the insertion surface (95) and the retaining surface (96) in the area of ​​the inner circle is rounded.

[0065] The insertion surface (95) forms a conical section of a right cone, the imaginary apex of which lies on the center line (14) outside the tool side (84). The imaginary apex angle of the insertion surface is 30 degrees.

[0066] The holding surface (96) is also designed as a conical section of a right cone. The imaginary apex of this cone lies outside the joining surface (83) on the center line (14). The apex angle of this imaginary cone is 90 degrees.

[0067] Figures 11 and 12 show a centering sleeve insert (101). This is used, for example, with the centering and anti-rotation bolts (33) described above. The illustrated centering sleeve insert (101) has a support spring (103), a centering sleeve (102), and a captive locking device (104).

[0068] In this embodiment, the support spring (103) is formed by a disc spring assembly (103). This disc spring assembly (103) is supported in the blind-hole-shaped sleeve receptacle (89).

[0069] The centering sleeve (102) has an interference fit with the sleeve receptacle (89), so that it is radially preloaded and fixed in the loose part (80). In the exemplary embodiment, this interference is three hundredths of a millimeter. This interference can be between one and ten hundredths of a millimeter. The centering sleeve (102), which is open at both ends, has an imaginary cylindrical outer contour. It has a longitudinal slot (105) of constant width. On the side facing away from the longitudinal slot (105), a deformation point (106) is formed, for example. In the illustration of Figure 11, this is a thin section adjacent to the support spring (103). The wall thickness of the centering sleeve (102) is reduced in this area, for example, to 50%. Instead of the thin section, a partial slot can also be arranged in this section. Other material weakenings are also conceivable.

[0070] The inner contour of the centering sleeve (102) is formed in two stages. The setting area (107) adjacent to the support spring (103) is cylindrical. Its diameter is, for example, one-tenth of a millimeter larger than the diameter of the cylindrical section of the centering and anti-rotation bolt (33). In the embodiment shown, the length of the setting area (107) is 20% longer than the length of the cylindrical section (36) of the associated centering and anti-rotation bolt (33).

[0071] A centering area (108) adjoins the setting area (107). This centering area (108) is shaped like a frustoconical shell. It widens from the setting area (107) towards the bolt receptacle (109). The opening angle corresponds to the cone angle of the conical section (35) of the associated centering and anti-rotation bolt (33). In the exemplary embodiment, the length of the centering area (108) is 95% of the length of the conical section (35).

[0072] In the exemplary embodiment, the locking device (104) has a locking pin (113) screwed into the loose part (80). In the illustrations of Figures 11 and 12, this pin engages in a recess (111) in the area of ​​the deformation point (106). For example, the locking pin has 0.03 millimeters of clearance in all directions relative to the centering sleeve (102). Under a load in the longitudinal direction (15), the centering sleeve (102) can move relative to the loose part (80), for example, when the support spring (103) is compressed. The locking device (104) can, for example, include a retaining ring, a press pin, etc., arranged above the centering sleeve (102) in the sleeve receptacle (89).

[0073] Figures 13 and 14 show a centering sleeve insert (101) with a centering sleeve (102) whose outer diameter is further reduced in a contact area (112) adjacent to the longitudinal slot (105) and adjacent to the deformation point (106). This contact area (112) is, for example, at 40 degrees with respect to a centering sleeve centerline oriented in the longitudinal direction (15). The outer diameter is 1.5% to 2% larger in a plane radial to the centering sleeve centerline than in the contact area (112) adjacent to the longitudinal slot (105). The wall thickness in the seating area (107) is, for example, 95% of the wall thickness in a plane normal to the longitudinal slot (105) and to the deformation point (106) in the contact area (112).

[0074] During the joining of the fixed part (20) and the loose part (80), the centering and anti-rotation bolts (33) engage in the centering sleeve inserts (101). The cylindrical sections (36) of the centering and anti-rotation bolts (33) are initially centered in the centering area (108) of the centering sleeves (102) and then move into the seating area (107). As the joining parts (20, 80) approach each other further, the conical sections (35) of the centering and anti-rotation bolts (33) contact the centering areas (108) of the centering sleeve inserts (101). The centering sleeves (102) are deformed and pressed against the wall of the sleeve receptacles (89). This compresses the support springs (103). They exert a force on the centering sleeves (102) oriented in the longitudinal direction (15) opposite to the centering and anti-rotation bolts (33). The wedge-shaped centering area (108) of the respective centering sleeve (102) is forced radially outwards in the sleeve receptacle (89).After assembly, the centering and anti-rotation bolts (33) are press-fitted into the centering sleeve inserts (101). Each centering and anti-rotation bolt (33) is thus seated with virtually no play in its respective centering sleeve insert (101). During assembly, the loose part (80) and the fixed part (20) achieve a high degree of positioning accuracy relative to each other. When the two parts (20, 80) are separated, the centering and anti-rotation bolts (33) are pulled out of the centering sleeve inserts (101). The retaining clip (104) prevents the centering sleeve insert (101) from coming loose from the loose part (80).

[0075] Figure 15 shows an interchangeable adapter system in its operating position. This interchangeable adapter system (10) has different geometric dimensions than the interchangeable adapter system (10) shown in Figures 1-12. The fixed part (20) and the loose part (80) are joined together in this illustration. The fixed part (20) and the loose part (80) abut each other at the interface (16). The centering and anti-rotation bolts (33) are firmly seated in the centering sleeve inserts (101). In the illustration of Figure 15, the cylindrical section (36) projects out of the centering sleeve (102) into the area of ​​the support spring (103). The support spring (103) may be compressed.

[0076] The locking bolt (61), biased by the spring (73), is in its operating end position. The locking piston (61) rests with its transition area (67) against the locking areas (45) of the engagement bolts (41). The engagement bolts (41) have moved radially outwards. The locking bolts (41) engage the retaining surface (96) of the retaining ring (91) with their engagement wedge surface (52). By radially moving the locking bolts (41), the two joining parts (20, 80) are pressed together at the interface (16) so that the two joining surfaces (31, 83) are securely in contact. The media transitions are connected to each other in a way that is both operationally reliable and leak-proof. In Figure 1, the loose part (80) is held in a storage station (140). The storage station (140) is, for example, fixed in space, e.g., on a tool changer rack. The storage station (140) is shown in Figures 16 and 17.It has two receiving channel sections (142) on one receiving side (141). These receiving channel sections (142) are arranged in a V-shape, spaced apart from each other. The apex of the imaginary V points downwards. The opening angle limited by the receiving channel sections (142) is, for example, 20 degrees. Each receiving channel section (142) has a receiving strip (143) and a retaining strip (144) that delimits the receiving channel section (142).

[0077] In the opening area of ​​the receiving channel sections (142), a locking plunger (145) projects from the receiving side (141). The locking plunger (145) is part of a locking assembly (146) arranged in the storage station (140). The free end face (147) of the locking plunger (145) is designed as a vertically oriented surface. It is also conceivable to design the end face (147) as an inclined surface. A rotation and removal lock (148) limits the movement of the locking plunger (145).

[0078] The locking plunger (145) is biased into an extended position by means of a plunger spring (149). In the exemplary embodiment, the plunger spring (149) is designed as a compression spring. Instead of the illustrated coil spring, an air spring can also be used as the plunger spring (149). The locking plunger (145) is supported against the plunger spring (149) by a plunger piston (151). The plunger piston (151) carries a sealing ring (152) which, in a plunger recess of the storage station (140), separates a spring chamber (153) from a pressure chamber (154). The pressure chamber (154) can, for example, be pneumatically actuated to retract the locking plunger (145) against the force of the plunger spring (149). It is also conceivable to reset the plunger piston (151) hydraulically, electrically, or magnetically. In the exemplary embodiment, the spring chamber (153) can also be actuated by a medium, electrically, or magnetically. It can, for example, be pneumatically actuated.In the exemplary embodiment, a sensor (157) for position detection of the locking plunger (145) is arranged in the housing (156) of the storage station (140). This sensor (157) can be monitored from the outside of the housing (156). This allows monitoring of a secure locked position and / or a secure release of the locking plunger (145).

[0079] A storage adapter sensor (158) is arranged on the receiving side (141) of the storage station (140). This storage adapter sensor (158) is dampened as soon as a storage adapter (120) is seated in the receiving channel sections (142). This storage adapter sensor (158) is used, for example, to enable subsequent functions, such as unlocking the exchange adapter system (10).

[0080] Figure 19 shows the storage adapter (120). In this illustration, it has holes for screws for fastening to the loose part (80). The storage adapter (120) has two rail sections (121) complementary to the inner sections (142) of the receiver. These rail sections (121) allow the loose part (80) to be held on the storage adapter (120), as shown in Figure 18. The two rail sections (121) together define, for example, a V- or U-shaped locking recess (122) that opens upwards. In the area of ​​the tip formed by the rail sections (121), the locking plunger guide recess (123) facing the storage station (140) can be chamfered. For example, the locking plunger guide recess (123) forms an angle of 30 degrees with a vertical plane. When inserting the storage adapter (120) into the storage station (140), the locking plunger (145) can be guided, for example, by means of this locking plunger guide recess (123).The storage adapter (120) is pushed into the storage station (140) against the force of the plunger spring (149). As soon as the storage adapter (120) is inserted into the storage station (140), the locking plunger (145) springs into the locking recess (122), relieving the plunger spring (149). The storage adapter (120) is now secured in the storage station (140).

[0081] In Figure 1, a release adapter (75) is attached to the fixed part (20). Figures 18 and 20 show the release adapter (75). The release adapter (75) has a projecting actuating element (76). In the exemplary embodiment, this is an actuating pin (76) that points towards the storage station (140). The actuating pin (76) has an end face (77) with a wedge-shaped end surface (78) that is chamfered in some areas. The angle of the wedge-shaped end surface (78) to a vertical plane can correspond to the angle that the locking plunger guide recess (123) forms with this plane.

[0082] As the fixed part (20) approaches the loose part (80) held in the storage station (140), the locking piston (61) in the fixed part (20) is lifted into the release position. The locking bolts (41) are now freely displaceable in the radial direction within the section defined by the stroke and rotation limit (42). Upon contact with the retaining ring (91), the return wedge surface (53) of the locking bolts (41) engages the insertion surface (95) of the retaining ring (91). The return wedge surface (53) and the insertion surface (95) slide against each other, displacing the locking bolts (41) radially inwards. As soon as the central plane of the locking bolts (41), oriented perpendicular to the longitudinal direction (15), passes the central plane of the retaining wedge (97) of the retaining ring (91), the locking piston (61) is released. The relaxing spring (73) and any additional pneumatic pressure that may have built up move the locking piston (61) downwards.The frustoconical portion (68) of the locking piston (61) initially engages the control area (47) of the locking bolts (41). The coefficient of friction p of this material pairing is, for example, between 0.03 and 0.07. Even if the contacting surfaces become smooth due to wear, the function is thus ensured. The locking bolts (41) are displaced radially outwards, engaging behind the retaining ring (91). When the locking piston (61) engages the control area (47), a high gear ratio is achieved, causing the locking bolts (41) to move radially by a large amount.

[0083] As soon as the frustoconical area (68) or the transition area (67) of the locking piston (61) reaches the damping area (46) of the locking pistons (41), self-locking occurs to prevent any potential return stroke. The locking bolts (41) cannot displace the locking piston (61). The design of the wedge mechanism, consisting of the locking piston (61) and the locking bolts (41), prevents the loose part (80) from being lost, even in the event of a spring (73) or pneumatic failure. The loose part (80) and the fixed part (20) are joined together.

[0084] As the fixed part (20) approaches the loose part (80) further, the frustoconical section (68) slides along the locking section (45). In this section, a higher force is transmitted by means of the wedge drive formed by the locking plunger (61) and the locking bolts (41), so that the locking bolts (41) securely engage the retaining ring (91). In this section, the transmission has a very low efficiency during a return stroke, e.g., less than 5%. The internal forces applied by the spring (73) are greater in the transmission section than the forces that can be applied to the engagement face (51) during operation and in the event of a malfunction. Thus, the geometric design of the locking section (45) prevents a return stroke of the locking piston (61).The aforementioned tolerance range of the slopes, together with the aforementioned coefficients of friction of the material pairing, ensures the aforementioned inhibition even in the event of possible wear of the contacting surfaces.

[0085] When the fixed part (20) is joined to the loose part (80), the centering and anti-rotation bolts (33) engage in the corresponding centering sleeves (102). This establishes the position of the fixed part (20) relative to the loose part (80). The position of the longitudinal slots (105) relative to the centerline of the exchange adapter system (10) ensures a secure fit of the centering and anti-rotation bolts (33) in the centering sleeve inserts (101) when the joining partners (20, 80) are subjected to circumferential load relative to each other.

[0086] When the loose part (80) is joined to the fixed part (20), the actuating pin (76) with its wedge-shaped end face (78) contacts the locking plunger (145). The locking plunger (145) is moved towards the storage station (140). The locking mechanism of the storage adapter (120) in the storage station (140) is released. When the fixed part (20) is lifted, the loose part (80) connected to it is removed from the storage station (140).

[0087] When the loose part (80) is placed in the storage station (140), the storage adapter (120) with, for example, the locking plunger guide recess (123) comes into contact with the locking plunger (145). The locking plunger (145) is then inserted.

[0088] After the loose part (80) is placed in the storage station (140), the locking piston (61) is first released, as described above. The fixed part (20) can now be lifted, with the locking plunger (145) engaging in the locking recess (122). The centering and anti-rotation bolts (33) are pulled out of the centering sleeve inserts (101). The fixed part (20) can now, for example, pick up another loose part (80) with a different tool.

[0089] It is conceivable to combine the individual implementation examples with each other.
