Description

[0001] The invention relates to a balancing adapter for a balancing device according to the preamble of claim 1, a balancing device with the balancing adapter according to claim 14 and a balancing adapter set according to claim 15.

[0002] Balancing devices are known in which the device has a stationary base station to which interchangeable balancing adapters can be attached. The balancing adapters are typically mounted on a drive spindle of the base station, which has a mounting for the balancing adapter and is part of the base station's drive mechanism for rotating the balancing adapter. Workpieces to be balanced, such as milling tools, tool holders, or pulleys, can be held or clamped in place using the balancing adapters connected to the base station. Once clamped, the workpieces can then be balanced using the balancing device.

[0003] The interchangeable balancing adapters differ primarily in their clamping systems and clamping dimensions or diameters for workpieces. Each balancing adapter is therefore designed for clamping a specific type of workpiece. For example, milling tools and tool holders are typically clamped using a balancing adapter that allows clamping from the outside. Certain pulleys or grinding wheels with a centrally located, cylindrical recess, on the other hand, are clamped using a balancing adapter that allows clamping from the inside. Overall, the interchangeable balancing adapters allow for particularly easy adaptation of the balancing device to different workpieces, making the device exceptionally flexible.

[0004] From DE 10 2007 036 144 A1, a balancing adapter for a balancing device is known, comprising a base body and an interchangeable body detachably connected to the base body. In a specific embodiment, the interchangeable body can have a clamping device for clamping a workpiece, which includes a clamping sleeve element with a clamping sleeve and a clamping element that is displaceable relative to the clamping sleeve element. The clamping sleeve has a cone, and the clamping element has a counter-cone corresponding to the clamping sleeve cone. By displacing the clamping element relative to the clamping sleeve element, the clamping diameter of the clamping sleeve can be adjusted under the influence of the cones, thus clamping a workpiece. The interchangeability of the interchangeable body allows the balancing adapter to be adapted to different workpieces to be clamped.Another document relevant to the invention concerning the prior art is patent document US 2015 / 123356 A1.

[0005] In the connected state, the base body and the interchangeable body are held coaxially to each other by rolling elements and clamped radially against each other. Each rolling element is positioned in a wedge-shaped gap between the base body and the interchangeable body, designed specifically for each rolling element. This wedge-shaped gap allows the respective rolling element to move deeper into the wedge-shaped gap during the connection process, thus achieving the desired radial clamping force. Such a connection between the base body and the interchangeable body is relatively complex.

[0006] The object of the invention is to provide a balancing adapter for a balancing device, in which a particularly simple and reliable balancing adapter design enables easy adaptation to different workpieces to be clamped. This object is achieved by the features of the independent claims. Preferred embodiments are disclosed in the dependent claims.

[0007] According to claim 1, a balancing adapter for a balancing device is proposed, comprising a clamping device for clamping a workpiece. The clamping device includes a clamping sleeve element with a clamping sleeve and a clamping element, in particular a rod-shaped element, that is displaceable relative to the clamping sleeve element. The clamping sleeve has a cone, and the clamping element has a counter-cone corresponding to the clamping sleeve cone. By displacing the clamping element relative to the clamping sleeve element, the clamping diameter of the clamping sleeve can be adjusted, particularly under the influence of the cones, and thus a workpiece can be clamped. Furthermore, the clamping sleeve element, which is particularly designed as an interchangeable part, can be detachably connected to a base body of the balancing adapter.According to the invention, the clamping sleeve element for connection with the base body has a ring flange with which the clamping sleeve element rests on an end wall of the base body, in particular an outer and / or ring-shaped, in the connected state of the clamping sleeve element and the base body.

[0008] In this way, the balancing adapter has a particularly simple and reliable design, as the clamping sleeve element now rests securely on the end face of the base body when connected to the base body. This support of the clamping sleeve element enables a particularly robust connection to the base body with low susceptibility to damage. Furthermore, this design allows the clamping sleeve element to be connected to and detached from the base body very easily and with minimal effort, making it easy to change the clamping sleeve element and adapt the balancing adapter to different workpieces being clamped or balanced.

[0009] In a preferred embodiment of the balancing adapter according to the invention, the clamping sleeve element can be detachably connected to the base body by means of at least one connecting element, in particular one associated with the ring flange, and in particular by means of several connecting screws. This allows the clamping sleeve element and the base body to be connected to each other simply and reliably. Preferably, the ring flange has several continuous recesses, in particular bores, through which the connecting screws are guided. The recesses can be arranged uniformly distributed around the ring flange in the circumferential direction. Preferably, the connecting screws are screwed into corresponding threaded bores in the base body, in particular into corresponding threaded bores in a housing part of the base body.

[0010] As an alternative to the connecting screws, it would also be possible, for example, to detachably connect the clamping sleeve element and the housing part using magnetic connecting elements or locking elements attached to the ring flange and / or the base body.

[0011] Preferably, the clamping sleeve element has a recess, particularly a continuous one, in which the rod-shaped clamping element is partially or completely received, with the clamping sleeve cone being formed as an internal cone by the recess. This allows a workpiece to be clamped simply and effectively. Advantageously, the clamping element can have a cylindrical section with which the clamping element, particularly with the interposition of a guide element, is guided linearly within the recess.

[0012] Preferably, the clamping sleeve element has a centering device for centering the clamping sleeve element, which is particularly rotationally symmetrical, relative to the base body. This effectively ensures that the clamping sleeve element connected to the base body is always in the desired position or orientation relative to the base body.

[0013] For reliable centering, the clamping sleeve element can have a centering rib projecting into an interior space of the base body and bearing against an inner wall of the base body, particularly a flat surface. Advantageously, the centering rib can be cylindrical, especially circular cylindrical.

[0014] In a preferred specific embodiment, the clamping sleeve element and / or a sleeve-shaped housing part of the base body connected to the clamping sleeve element can be essentially rotationally symmetrical.

[0015] For effective clamping of a workpiece, the clamping sleeve element can have a support surface surrounding the clamping sleeve on the outside for a workpiece to be clamped and / or for an adapter element, in particular a disc-shaped one, wherein a workpiece placed on the support surface or the adapter element can be clamped by means of the clamping device, in particular from the inside.

[0016] Advantageously, the rod-shaped clamping element can be detachably connected at one end to an actuating element of the balancing adapter, in particular a rod-shaped one, for displacing the clamping element relative to the clamping sleeve element.

[0017] Preferably, the clamping element can be screwed to the actuating element at its end region to enable a simple and quick connection between the two. To achieve this screw connection, the clamping element can have several spaced-apart grooves at its end region, particularly helical grooves extending over a portion of its circumference, into which engagement elements, especially balls, associated with the actuating element can be inserted.

[0018] In a preferred specific embodiment, the rod-shaped clamping element can be designed in multiple parts, wherein the clamping element has a rod-shaped base part and a connecting part connected to the base part, which encompasses the base part in a ring-like manner and is in particular sleeve-shaped, for connecting the clamping element to the actuating element.

[0019] Preferably, the clamping sleeve element and the clamping element form an interchangeable unit that can be detachably connected to the base body of the balancing adapter. This allows the clamping sleeve element and the clamping element to be connected to the base body particularly easily.

[0020] Preferably, the balancing adapter includes a part of a drive unit, in particular a pneumatically operated one, for the linear displacement of the clamping element relative to the clamping sleeve element. Specifically, the balancing adapter can have a piston of a cylinder-piston unit as a drive unit, which is coupled indirectly, in particular via a rod-shaped actuating element, or directly to the clamping element.

[0021] In a preferred specific embodiment, the base body comprises a housing part, in particular a sleeve-shaped one, comprising the end wall, and an actuating assembly, in particular connected to the housing part by means of several connecting screws, comprising the actuating element and the part of the drive device.

[0022] In a further embodiment, the clamping sleeve can be provided with slots distributed around its circumference, particularly those extending radially, to adjust the clamping diameter. Such slots allow the clamping diameter of the clamping sleeve to be adjusted easily and effectively to the desired extent. Preferably, the clamping sleeve is closed at a free end over its entire circumference. This facilitates particularly easy clamping of a component from the inside.

[0023] Furthermore, a balancing device with the balancing adapter according to the invention is also claimed.

[0024] The advantages resulting from the balancing device according to the invention are identical to the advantages of the balancing adapter according to the invention already acknowledged, so that these will not be repeated here.

[0025] Advantageously, the balancing device can have a base station with a balancing adapter receptacle for receiving the balancing adapter. Preferably, the base station has a rotary drive for rotating the received balancing adapter and / or at least part of a drive unit for, in particular linearly, displacing the clamping element relative to the clamping sleeve element.

[0026] Furthermore, a balancing adapter set is also claimed, comprising several clamping sleeve elements, at least one, in particular several, clamping elements corresponding to the clamping sleeve elements, in particular rod-shaped, and a base body, wherein each clamping sleeve element has a clamping sleeve and the individual clamping sleeve elements differ at least in the design of their clamping sleeves, in particular in the outer diameter of their clamping sleeves, wherein the clamping sleeve of each clamping sleeve element has a cone and the at least one clamping element has a counter-cone corresponding to the clamping sleeve cone, and wherein each clamping sleeve element is detachably connectable to the base body, wherein each clamping sleeve element has an annular flange for connection to the base body, with which the clamping sleeve element in the connected state of clamping sleeve element and base body, in particular in a planar contact, on a, in particular outer and / or annular,front wall of the base body rests on it.

[0027] The balancing adapter set according to the invention provides a modular structure by means of which the balancing adapter can be easily adapted to different workpieces to be clamped.

[0028] The advantageous embodiments and / or further developments of the invention described above and / or set out in the dependent claims can be used individually or in any combination with each other, except for example in cases of clear dependencies or incompatible alternatives.

[0029] The invention and its advantageous embodiments and / or further developments, as well as their advantages, are explained in more detail below using drawings as examples only. They show:

[0030] Fig. 1 shows a perspective view of a first embodiment of a balancing adapter according to the invention; Fig. 2 shows a sectional view along the section plane AA. Fig. 1 Fig. 3 shows a side view of an interchangeable assembly of the balancing adapter; Fig. 4 shows a perspective view of a second embodiment of a balancing adapter according to the invention; Fig. 5 shows a sectional view along the section plane BB. Fig. 4 ; Fig. 6 in a representation according to Fig. 5 a third embodiment of a balancing adapter according to the invention; and Fig. 7 in a representation according to Fig. 6 a fourth embodiment of a balancing adapter according to the invention.

[0031] In Fig. 1 Figure 1 shows a first embodiment of a balancing adapter 1 according to the invention. The balancing adapter 1 has a connecting device 3 with which the balancing adapter 1 can be connected to a Fig. 2The balancing adapter 1 can be connected to or fixed at the stationary base station 5, indicated by dashed lines. Together with the base station 5, the balancing adapter 1 forms a balancing device 7, which can be used to balance workpieces.

[0032] The base station 5 has a drive spindle 9, also indicated here by dashed lines, with a balancing adapter receptacle 11 in which the balancing adapter 1 with a receiving area 12 can be positioned. The drive spindle 9 is part of a drive unit of the base station 5 (not shown here) for a rotary drive of the balancing adapter 1. To attach the balancing adapter 1 to the balancing device 7, the balancing adapter 1 with the receiving area 12 is inserted into the balancing adapter receptacle 11 until an outwardly projecting ring flange 13 of the connecting device 3 rests on the drive spindle 9. The balancing adapter 1 is then screwed to the drive spindle 9 by means of several connecting screws 14, each connecting screw 14 being guided through a continuous recess or bore in the ring flange 13 and screwed into a corresponding threaded bore in the drive spindle 9.

[0033] As from Fig. 2As further shown, the balancing adapter 1 has a base body 15 with a sleeve-shaped housing part 17, which is essentially rotationally symmetrical. The outwardly projecting annular flange 13 of the connecting device 3 is formed on the housing part 17. The base body 15 also has an actuating unit 19 connected to the housing part 17 for actuating a clamping device 21 of the balancing adapter 1. A workpiece to be balanced can be clamped onto the balancing adapter 1 by means of the clamping device 21. The connection between the housing part 17 and the actuating unit 19 is made by means of several connecting screws 23. Each connecting screw 23 is guided through a through-hole or bore in a housing part 25 of the actuating unit 19 and screwed into a corresponding threaded bore in the housing part 17 of the base body 15.

[0034] According to Fig. 2The housing part 17 of the base body 15 is also detachably connected here to a clamping sleeve element 27 of the clamping device 21, which has a clamping sleeve 26. For this purpose, the clamping sleeve element 27 has an outwardly projecting annular flange 29, with which the clamping sleeve element 27, in the connected state of clamping sleeve element 27 and housing part 17, rests in planar contact with an outer annular end wall 31 of the housing part 17.

[0035] The connection of the clamping sleeve element 27 to the housing part 17 is achieved here by means of several connecting screws 33. Each connecting screw 33 is guided through a continuous recess or bore in the ring flange 29 and screwed into a corresponding threaded bore in the housing part 17 of the base body 15. The continuous recesses of the ring flange 29 are, by way of example, arranged evenly distributed around the circumference of the clamping sleeve element 27, which is essentially rotationally symmetrical. Fig. 1 In the connected state of clamping sleeve element 27 and housing part 17, the screw heads of the connecting screws 33, which abut the clamping sleeve element 27, are also countersunk or completely received in recesses or bores 35 on the clamping sleeve element 27.

[0036] Thus, to connect the clamping sleeve element 27 to the base body 15, the clamping sleeve element 27 is first placed onto the base body 15 so that the clamping sleeve element 27 rests with the ring flange 29 on the end wall 31 of the housing part 17. The clamping sleeve element 27 and the housing part 17 are then connected to each other by means of the connecting screws 33. In this way, the clamping sleeve element 27 can be connected to the base body 15 in a simple and robust manner. This type of detachable connection between the clamping sleeve element 27 and the base body 15 also reliably ensures that the balancing adapter 1 always exhibits a high degree of balance when the base body 15 is connected to different clamping sleeve elements 27.Optionally, each connecting screw 33 could be further secured in the respective recess of the ring flange 29 with a retaining ring, in particular a snap ring, such that the connecting screws 33 cannot be removed from the recesses or fall out when the connection between the clamping sleeve element 27 and the housing part 17 is loosened. This ensures a particularly high degree of balance of the balancing adapter 1.

[0037] As an alternative to the connecting screws 33, it would also be possible, for example, to connect the clamping sleeve element 27 and the housing part 17 to each other in a detachable manner by means of magnetic connecting elements or locking elements attached to the ring flange 29 and / or the housing part 17.

[0038] As in Fig. 2As further shown, the clamping sleeve 26 of the clamping sleeve element 27 is connected with an end region 37 to a base region 39 of the clamping sleeve element 27, which has the ring flange 29. Here, the clamping sleeve 26 and the base region 39 are, by way of example, formed in one piece. In addition, the clamping sleeve 26 has several slots 41 evenly distributed around its circumference in a central region. Fig. 3 ) by means of which the clamping diameter of the clamping sleeve 26 can be adjusted to the desired extent. At a free end 43, the clamping sleeve 26 is also closed over its entire circumference, i.e., it is not slotted. Furthermore, the clamping sleeve 26 has an internal cone 83 with a cross-section that decreases towards the base region 39 and extends essentially over the entire length of the clamping sleeve 26.

[0039] According to Fig. 2The clamping sleeve element 27 also has a continuous recess 45 in which a clamping element 47, in this example a rod-shaped element, is partially received. The continuous recess 45 also forms the inner cone of the clamping sleeve 26. The rod-shaped clamping element 47 has a section 49 with an outer cone, with which the clamping element 47 abuts or can be brought into contact with the clamping sleeve 26. Furthermore, the clamping element 47 also has a cylindrical section 51, with which the clamping element 47, in this example with an intermediate ball guide, is guided linearly displaceable in the recess 45. The ball guide is held captive in the recess 45 by means of a retaining ring 53 screwed into a threaded bore of the clamping sleeve element 27.

[0040] By displacing the clamping element 47, which is arranged in the recess 45, downwards relative to the clamping sleeve element 27, or towards the housing part 25, the clamping sleeve 26 is pressed outwards by the action of the outer cone of the clamping element 47 and the inner cone of the clamping sleeve 26, thus increasing the clamping diameter of the clamping sleeve 26. In this way, a workpiece placed on a support surface 55 of the clamping sleeve element 27 can be clamped from the inside. The support surface 55 surrounds the clamping sleeve 26 on the outside in a ring shape.

[0041] Alternatively, a workpiece could also be placed on an adapter element, in particular a disc-shaped one, which is not shown in the figures and rests on the support surface 55.

[0042] To release a clamped tool, the clamping element 47 is moved in the opposite direction or upwards relative to the clamping sleeve element 27, so that the clamping diameter of the clamping sleeve 26 is reduced.

[0043] Furthermore, the clamping sleeve element 27 also has a centering device for centering the clamping sleeve element 27 relative to the base body 15. The centering device is formed by a centering rib 61 of the base area 39 of the clamping sleeve element 27, which projects into an interior space 57 of the base body housing part 17 and abuts an inner wall 59 of the housing part 17. Optionally, a guide element, in particular a ball guide, could be arranged between the centering rib 61 and the housing part 17, with which the clamping sleeve element 27 is guided linearly relative to the housing part 17 when the connecting screws 33 are unscrewed. In addition, the base area 39 also has a guide area 63 projecting from the centering rib 61 and also projecting into the interior 57 of the housing part 17, in which the clamping element 47 is guided in a linearly displaceable manner.

[0044] As in Fig. 2As further shown, the rod-shaped clamping element 47 projects from the clamping sleeve element 27 with an end region 65. The clamping element 47 is also designed in two parts. It comprises a rod-shaped base part 67 and a sleeve-shaped connecting part 69, which is connected to the base part 67 at the projecting end region 65 and surrounds the base part 67 in an annular manner. The clamping element 47 can be detachably connected to an actuating element 71 of the actuating assembly 19, shown here as an example, by means of the connecting part 69. For connection to the rod-shaped base part 67, the sleeve-shaped connecting part 69 has an internal thread, allowing the connecting part 69 to be screwed onto the base part 67, which has a corresponding external thread. The clamping sleeve element 27 and the clamping element 47 together form an interchangeable assembly 73. Fig. 3) which can be detachably connected to the base body 15 of the balancing adapter 1 by means of the connecting screws 33.

[0045] For the detachable connection of clamping element 47 and actuating element 71, the clamping element 47 can be screwed to the actuating element 71 here. For this purpose, the sleeve-shaped connecting part 69 has several spaced-apart grooves 75, which in some areas extend helically over a partial circumference of the connecting part 69 ( Fig. 3 ) into which balls 77, held at an end region 99 of the rod-shaped actuating element 71, can be inserted as engagement elements in a contour-adapted manner. The balls 77 are arranged in continuous recesses as ball receptacles of the actuating element 71, with the balls 77 projecting with a partial portion inwards into a clamping element receiving space of the actuating element 71. In addition, the balls 77 are secured by means of a pressed-on retaining ring 79 ( Fig. 2 ) held in the recesses.

[0046] For screwing the rod-shaped clamping element 47 to the actuating element 71, the clamping element 47 has a drive profile 101 arranged on its end face, here by way of example an internal hexagon. When the clamping element 47 is screwed to the actuating element 71, the opposite end face of the clamping element 47 also comes into contact with a spring element 81, here by way of example made of rubber, arranged in the clamping element receiving space of the actuating element 71.

[0047] Furthermore, the rod-shaped actuating element 71 is connected at its other end to a piston 85 of the actuating unit 19 in a rotationally fixed manner. The piston 85 is part of a pneumatically operated cylinder-piston unit of the balancing device 7, which forms a drive unit or actuator for the linear displacement of the actuating element 71 and thus also of the clamping element 47 of the balancing adapter 1 coupled to it. The other components of this drive unit are part of the base station 5 of the balancing device 7. Compression springs, not shown in the figures, are also arranged between the piston 85 and the housing part 25 of the actuating unit 19, which exert an axial preload on the piston 85 downwards away from the housing part 25.

[0048] Specifically, the actuating element 71 is connected to the piston 85 by means of a screw connection, wherein a screw 89 is guided through an axially through recess in the piston 85 and screwed into a threaded bore on the end face of the actuating element 71. The end region of the actuating element 71 has circumferential recesses into which cylindrical pins 91 of the piston 85 engage in a contour-adapted manner, so that rotation of the actuating element 71 relative to the piston 85 is prevented.

[0049] Furthermore, the rod-shaped actuating element 71 can be linearly displaced between a starting position and an end position by means of the piston 85. Fig. 2The actuating element 81 is in its end position. In the starting position, the actuating element 85 is displaced downwards compared to the end position. By displacing the actuating element 71, the clamping element 47 coupled to the actuating element 71 is also displaced, and thus the clamping element 47 is displaced relative to the clamping sleeve element 27.

[0050] In the Fig. 4 and 5 A second embodiment of a balancing adapter 93 according to the invention is shown. Compared to the one described in the Figs. 1 to 3The balancing adapter 1 shown comprises a clamping element 95 and a clamping sleeve element 97. The clamping sleeve element 97 has a clamping sleeve with a larger sleeve diameter compared to the clamping sleeve 26. Accordingly, the outer conical section of the rod-shaped clamping element 95 also has a larger diameter. Furthermore, the clamping element 95 does not have a separate connecting part for connection to the actuating element 71. Instead, the clamping element 95 is formed as a single piece.

[0051] In Fig. 6 A third embodiment of a balancing adapter 102 according to the invention is shown. Compared to the one described in the Fig. 4 and 5The balancing adapter 93 shown has a clamping sleeve element 104. The clamping sleeve element 104 has a stop surface 103 as a stop for the clamping element 95. This stop surface 103 limits the clamping travel of the clamping element 95 downwards, thus effectively counteracting excessive expansion of the clamping sleeve 26. The stop surface 103 is formed by an inwardly projecting annular shoulder of the clamping sleeve element 104.

[0052] In Fig. 7 A part of a fourth embodiment of a balancing adapter 105 according to the invention is shown. Compared to the one in the Fig. 4 and 5In the balancing adapter 93 shown, the balancing adapter 105 has a clamping sleeve element 107. The clamping sleeve element 107 has a stop ring 109 screwed into a threaded bore, the end face of which forms a stop surface 111 for the clamping element 95. The stop ring 109 surrounds a section of the clamping element 95 in an annular manner and, by way of example, has several circumferentially distributed recesses, in particular bores, for screw actuation of the clamping element 95 by means of a suitable actuating element. By further screwing the stop ring 109 into the threaded bore or by unscrewing the stop ring 109 from the threaded bore, the downward clamping travel of the clamping element 95 or the maximum expansion of the clamping sleeve 26 can be adjusted. This can be used, for example, to adjust or limit the clamping pressure for pressure-sensitive workpieces.Optionally, a locking element, in particular a lock nut, could also be screwed into the threaded bore to reliably hold the stop ring 109 in the desired position.
