    [1] The invention relates to a finishing device comprising a finish stone, a finish stone holder for tilting the finish stone and a pivot drive for pivoting the finish stone about a finish stone pivot axis, the pivot drive comprising a drive device for generating a drive movement and a transmission device for producing a pivot stone. .
    [2] The final machining of a workpiece is also referred to as a "superfinish" or "finishing process" process for finishing a workpiece. In these procedures, an abrasive finishing stone is pressed against the workpiece surface to be machined. Usually, the rotation is superimposed on the workpiece surface to be machined with an oscillating motion, in which the finishing tool and the workpiece surface to be machined are moved relative to each other in directions parallel or inclined to the axis of rotation.
    [3] The final machining of workpieces is also used for machining rotationally symmetrical workpiece surfaces which have a curved profile. Examples of such workpieces are roller bearing rings or roller bearing bodies. Such strong workpiece surfaces are machined with finish stones, which pivot back and forth about a finish stone pivot axis. For this purpose, a drive device is used, which generates a drive movement, which is transmitted to an arch movement of the finish stone by means of a transmission device.
    [4] For precise surface treatment of a particularly curved workpiece surface, it is required that the drive device is as torsionally rigid as possible. At the same time, it is unfortunate to be able to use the actual finishing device for workpieces with different sizes of inboard.
    [5] An object of the present invention is to provide a device for finishing machining, which lights up for workpieces with mutually different mats, which allows as precise machining of curved workpiece surfaces as possible.
    [6] The finish processing device according to the invention is based on the idea that the drive movement generated by the drive device is then transferred in the pregnancy of a first swing arm and then the swing movement of the first swing arm is then passed via a transfer drive to a second finisher, which finishes the finisher. the means the other pivot arm is pivotable about a finish stone pivot axis.
    [7] The finishing device according to the invention makes it possible to reduce the structural distance between the first pivot arm and the drive device, so that even this area of the finishing device can be formed particularly rigidly. The pivot drive according to the invention is then, despite the additional transfer drive and the second pivot arm, more torsionally rigid than a conventional construction, in which the drive movement of the drive device is transmitted via space-gripping rigid arm of a single pivot arm, which then carried the finish stone.
    [8] The finishing device according to the invention has the further advantage that the second pivot arm can have a generally shorter length, so that even (concavely) curved inner surfaces of roller bearing outer rings can be machined with relatively compact mats.
    [9] The finishing device according to the invention is overall very compact, so that it is also suitable for machining roller bearing rings with very large diameters.
    [10] A further part of the fairing with the finishing device according to the invention consists in that it is also selected for machining convexly curved workpiece surfaces, for example of thin-shaped roller bearing bodies.
    [11] In a hazardous embodiment of the invention it is provided that the pivotal movements of the first pivot arm and the second pivot arm are identical. This has the advantage that the definition of the arch movement of the other arch arm can be modeled particularly easily. 90707 3
    [12] It is further preferred that the first pivot arm is pivotable about an additional pivot axis, which in particular runs parallel to the finish stone pivot axis. The additional pivot axis allows a simple bearing definition of the first pivot axis.
    [13] It is further preferred that the additional pivot axis is defined by an additional pivot bearing. In the case of such an additional arch bearing, it may be a pivotable, but not releasable connection between the first arch arm and a frame or a stand. However, it is also possible for the connection between the first swing arm and the frame to be releasable, so that the finishing device according to the invention can also be used for generating a linear oscillation movement of the finishing stone.
    [14] Advantageously, the finishing device comprises a workpiece drive for generating a rotational movement of a workpiece to be machined about an axis of rotation, the axis of rotation projecting parallel to a plane within which the finish stone pivot axis and the further pivot axis run. Della enables a particularly simple final machining of a rotationally symmetrical workpiece.
    [15] For machining concavely curved workpiece surfaces, it is preferred that the finish stone pivot axis runs through the finish stone, especially between the finish stone holder and an effective surface of the finish stone.
    [16] For final machining of convexly curved workpiece surfaces, it is preferred that the finish stone pivot axis runs offset to the finish stone, especially on a side of the finish stone away from the finish stone holder.
    [17] In a preferred embodiment of the transmission drive, two transmission links are provided, which are pivotally connected to the first pivot arm and to the second pivot arm, respectively. The transfer slats allow a particularly simple transfer of the first movement of the first pregnant arm to the second pregnant arm with small torsion.
    [18] Furthermore, line control devices are provided for controlling the transmission links, by means of which the transmission links are controlled in mutually parallel control directions. This makes it possible to have a simple definition of a parallel mutation in the Transmission Lines.
    [19] Finally, it is preferred that a bearing device is arranged for storing the line control devices along a path transverse to the control directions, in particular along a path perpendicular to the control directions. This may provide a stable cruciate ligament device with little friction.
    [20] Further features and advantages of the invention will become apparent from the following description and the preferred embodiments as shown in the drawings.
    [21] In the drawings: Fig. 1 shows a side view of an embodiment of a finishing device; Fig. 2 is a front view of the finishing device according to Fig. 1; Fig. 3 is a side view of a finishing device according to the figure when machining a workpiece in the form of a roller bearing ring, showing each other the superimposing intermediate layer and the two layers of a finishing stone; Fig. 4 is a view corresponding to that of Fig. 3, the intermediate layer being changed compared with the intermediate layer in Fig. 3; Fig. 5 is a side view of a further embodiment of a finishing device, which is specially lamped for processing roller bearing bodies; and Fig. 6 is a front view of the finishing device according to Fig. 5.
    [22] An embodiment of a finishing device is shown in Figs. 1 to 4 and is designated there in its entirety by the male reference numeral 10.
    [23] The device 10 comprises a fixed or by means not shown drives displaceable frame or frame 12, a drive device 14 for generating a drive movement and a transmission device 16 for generating a pivot movement of a finish stone 18 about a finish stone pivot axis 20. 90707
    [24] The drive device 14 comprises a drive motor 22, which is, for example, fixedly connected to the frame 12. However, it is preferred that the layer Mr drive motor 22 relative to the frame 12 can be moved along an adjustment shaft 24. For this purpose an adjustment device (not shown) can be used, which supports on the frame 12 and enables a layer-changeable fixation of the drive motor 22 to the frame 12.
    [25] The drive motor 22 serves to generate a rotational movement of a drive pulley 26 about a drive shaft 28.
    [26] A connecting rod bearing 30 is mounted to the drive pulley 26 and more specifically around a connecting rod bearing shaft 32, which is eccentrically offset from the drive shaft 28.
    [27] The connecting rod bearing 30 serves for storing a connecting rod 34, which in the event of a connecting rod carries an additional connecting rod bearing 36, which serves for pivotally connecting the connecting rod 34 to a first connecting arm 38.
    [28] The first pivot arm 38 is pivotable by means of a further pivot bearing 40 about an additional pivot shaft 42 mounted to the frame 12.
    [29] The finishing device 10 further comprises a transfer drive 44 for transferring an arch movement of the first pivot arm 38 to a second pivot arm 46.
    [30] The transfer drive 44 comprises two transfer links 47, 48. The transfer links 47, 48 are arranged inboard parallel. They are pivotally connected at one end to the first pivot arm 38 by means of a bearing 50 and in the second spirit to the second pivot arm 46 by means of a bearing 52.
    [31] The transmission drive 44 comprises two line control devices 54, 56 for controlling a respective transmission hose 47, 48 in inboard parallel control directions 58 and 60.
    [32] The line control devices 54, 56 are in turn displaceably mounted by means of a bearing device 62 and more precisely along a path 64 which runs transversely, in particular perpendicular to the control directions 58 and 60. 90707 6
    [33] The bearing device 62 comprises a preferably frame-fixed bearing rail 66, along which separate bearing slides 68 and 70 are guided along the path 64. The bearing slide 68 carried the line guide device 54 for the transfer link 47. The bearing slide 70 carried the line guide device 56 for the transfer link 48.
    [34] The second swing arm 46 comprises a Finnish stone holder, designated in its entirety by the designation 72. The finish stone holder 72 comprises a housing 74, which preferably also supported the bearing 72.
    [35] In the housing 74 a guide rod 76 is controlled, which in one spirit carried a holder 78 for the finish stone 18. In the other second the guide rod 76 is actuated by a pressure force by means of a pressure device 80, the pressure force being exerted by the finish stone 18 via the holder 78. an action surface 82 on the finish stone 18 against a workpiece surface to be finished. In addition, the pressure device 80 provides a return of the finish stone 18 in the direction of a workpiece, when the finish stone nOts.
    [36] The finishing device 10 enables the final machining of curved workpiece surfaces. A typical workpiece 84 is shown in Figs. 3 and 4. The workpiece 84 is in particular a roller bearing ring, which has a curved workpiece surface 86. This workpiece surface is, for example, the (concavely curved) inner side of an outer ring of a roller bearing. .
    [37] The workpiece 84 is driven for its final machining by means of a drive device 88, which is per se in itself and is only clearly shown. The workpiece 84 thereby rotates about a central axis of rotation 90.
    [38] The axis of rotation 90, the finish stone pivot axis 20 and the further pivot axis 42 are preferably so directed, that the axis of rotation 90 is parallel to a plane 92, within which the finish stone pivot axis 20 and the further pivot axis 32 10. In addition, the finish stone pivot axis 20 and the additional pivot axis 41 are preferred in parallel with each other.
    [39] The finishing device 10 described above operates as described below and especially with reference to Fig. 3. The drive motor 22 sets the drive pulley 26 in a rotational movement, which is converted into a pivotal movement of the first pivot arm 38 about the further pivot shaft 42 via the connecting rod bearing 30. , the connecting rod 36 and the additional connecting rod bearing 36. In this case, the first pivoting arm 38 pivots about a central position 0 between a first abutment I and behind the second abutment II. The pregnancy of the first forearm arm 38 is transmitted by means of the overpassing links 47 and 48 so that the second forearm arm 46 swings synchronously with the first forearm arm 38, i.e. also around a middle layer 0 and between a first breath and I and a second breath II. With the pivotal movement of the pivot arms 38 and 46, the transfer lanes 47 and 48 are maneuvered substantially parallel to their directions of extension and are thereby displaced within the line guide devices 54 and 56. The line guide devices 54 and 56 are in turn maneuvered by maneuvering the bearing slides 68 and 70 along the bearing rail 66.
    [40] The intermediate layer 0 for the first pivot arm 38 and thus also the intermediate layer 0 for the second pivot arm 46 can be dangerously adjusted. For this purpose, the drive motor 22 is adjustable relative to the frame 12 along the adjustment shaft 24. This is shown in Fig. 2 also with a double arrow 94 in the area where the connection between the frame 12 and the drive motor 22 is made.
    [41] When the drive motor 22, starting from the relative layer of the drive motor 22 and the frame 12 shown in Fig. 3, assumes a position in which the drive shaft 28 is further at a distance from the frame 12, the intermediate layer 0 of the first pivot arm 38 is pushed further into direction of the drive motor 22. The bearings I and II are then moved in the corresponding manner, as shown in Fig. 4.
    [42] In a further operating mode of the finishing device 10, this can be used as a line curvature unit. If this is read, the connection in the area of the pivot bearing 40 between the first pivot arm 38 and the frame 12 is blocked. This results in the rotational movement of the drive pulley 26 being converted into a rectilinear reciprocating motion of the pivot arm 38 and via the override drive 44 into a rectilinear reciprocating motion of the finish stone 18. Thereby the finish stone action surface 82 moves separately parallel to the axis of rotation 90.
    [43] In the above-described machining of a concave curved workpiece surface 86, the finish stone pivot axis 20 passes through the finish stone 18. However, it is also possible for the finish stone pivot shaft 20 to be arranged outside the finish stone 18. This device is particularly suitable for machining convexly curved workpiece surfaces. 86. Such a workpiece machining will be described in the following with reference to Figs. 5 and 6:
    [44] The moving workpiece 84 is, for example, a barrel-shaped roll body with a (convexly curved) workpiece surface 86. The workpiece 84 is driven on the above-described manner rotating about a central axis of rotation 90 by means of a drive device 88. The workpiece surface 86 to be machined has a hook center , which runs through the finish stone pivot axis 20. The finish stone pivot axis 20 is arranged outside the finish stone 18.
    [45] The embodiment of a finishing device 10 shown in Figs. 5 and 6 corresponds in structure and in function to the finishing device according to Fig. 1 and Fig. 4. Reference is made to the above description. In the following, only the differences between the finishing device 10 according to Figs. 5 and 6 and the finishing device 10 according to Figs. 1 to 4 will be treated.
    [46] At the finishing device 10 according to Figs. 5 and 6, a first pivot arm 38 is arranged, which has a greater length than the second pivot arm 46, so that the above-described configuration of arranging the finish stone pivot axis 20 is possible outside the finish stone 18.
    [47] In order to enable the installation of the hooking radius 96 between the finish stone swivel shaft 20 and the workpiece surface 86 to be machined, the transfer hoses 47 and 48 are not directly (for example when using bearings 50) connected to the first swing arm 38, but with an intermediate coupling 98 , the bearing of which can be adjusted along the forearm arm 38. 90707 9
    [48] For installability of the layer for the slide 98 relative to the pivot arm 38, the slide 98 has a section 100 (for example a spindle nut) which can be maneuvered, which section is driven by means of a drive section 102 (for example a spindle). The drive section 102 can be installed by motor or manually, for example by means of a raft 104. A rotation of the steering wheel 104 causes a rotation of the drive section 102 and thereby a linear displacement of the driven section 100 and the slide 98. In this way the connecting rod 34 is displaced in a direction parallel with the direction of extension of the first forearm 38.
    [49] For the above-described installation of the layer for the connecting rod bearing 36 relative to the first pivot arm 38 does not occur simultaneously with a displacement of the intermediate layers 0 (cf. Figs. 3 and 4) for the first pivot arm 38 and the second pivot arm 46, a further drive unit 106 is provided, which is likewise shaped like a spindle, which can be driven by a motor or manually, for example by means of a raft 108. The drive unit 106 is coupled to the drive motor 22 and influences its displacement in a direction parallel to the extension direction of the first pivot arm 38. . 90707 1
