Definitions

  • the present invention relates to a method of machining particularly rotationally symmetrical workpieces, e.g. Vehicle rims.
  • the workpiece is simultaneously rotated by a first drive motor about its own vertical central axis, it is moved by a second drive motor with its central axis along an orbital motion along a closed orbit about a rotating vertical axis and this vertical axis is by means of a third Drive motor rotated about a stationary vertical axis of rotation.
  • a third Drive motor rotated about a stationary vertical axis of rotation.
  • the orbital movement and the rotational movement of the workpiece is accomplished by means of two separate drive motors, whereby these two drives are independently controlled separately and are no longer firmly coupled.
  • a plurality of workpieces may be dipped into the container and moved relative to the container, all workpieces being rotated about their own vertical center axis, about the rotating vertical axis and about the stationary vertical axis of rotation.
  • this method there is the advantage that any processing shadows are minimized, since each workpiece is rotated about its own central axis and thus no part of the workpiece rotates on a circular path, on which the part is always directed to the center of this circular path.
  • the workpiece can be moved in a rotational direction along the closed orbit, wherein the workpiece is moved in the opposite direction of rotation about its own central axis.
  • none of the drive motors is subjected to a rotary or orbital movement. This contributes to a long life of the device, since the two drive motors need only be subjected to the oscillatory movement, which, however, takes place at a comparatively low speed.
  • a wobbling motion can additionally be imposed on the workpiece in order to further increase the relative movement between the processing means and the workpiece.
  • the two drive motors are mounted on a component which is either stationary, for example, when the processing agent container is oscillated, or which is oscillatable by an oscillating device.
  • the two electric motors no quick rotational movements but only a comparatively slow oscillatory motion are subjected.
  • the orbital drive to a rotatably driven by a drive motor component on which the chuck is eccentrically and rotatably mounted.
  • the chuck which rotates along the orbital path, can rotate about its own axis with a drive motor that does not orbit itself along the orbital path, but remains stationary compared to the movement of the workpiece.
  • the rotation device it may be advantageous for the rotation device to have a shaft which is rotatably driven by the other drive motor and which extends through the component and which is in rotary connection with the chuck.
  • a third drive motor can be provided, with which the vertical axis is rotatable about a stationary vertical axis of rotation, so that on the one hand rotates the workpiece about its own central axis and on the other hand rotates the workpiece on an orbital path and to the stationary vertical axis of rotation rotates.
  • the rotation means may comprise a plurality of chucks which can be rotated about their own central axis either via a common transmission, for example a planetary gear, or via their own drive.
  • the chucks are arranged coaxially with each other and on the one hand about their own axis of rotation, on the other hand rotated about the rotating axis of rotation and finally also about the stationary axis of rotation, whereby best machining results are achieved.
  • inventive method is basically suitable for all workpieces and in particular for rotationally symmetrical workpieces.
  • rims all kinds of rims or wheels, i. Rims for cars, trucks or motorcycles in all sizes and variations.
  • the machining may be deburring, descaling, rounding, grinding, polishing or the like.
  • the processing device shown has a base frame 10, on which a processing agent container 12 is arranged.
  • the processing agent container 12 is formed in the illustrated embodiment, round and open at the top, but may also be trough-shaped or trough-shaped.
  • the processing agent container 12 is not in any fixed connection with the base frame 10 and can thus be easily replaced by industrial trucks.
  • a vibration drive may additionally be provided.
  • various supply and discharge possibilities are provided on the processing medium container 12 in order to continuously add or remove water and / or treatment agents (compounds). In operation, the container 12 is filled to about the level of level N with processing means.
  • a stirring element 14 is provided, which has a plurality of parallel to the bottom extending paddle, which is driven by a drive 16, which is located below the container bottom, about a vertical axis of rotation D rotating.
  • a machine stand 18 is arranged on the base frame 10, on which a cross-beam 20 in the vertical direction, that is along the double arrow X, slidably mounted.
  • the vertical movement is effected via a drive 22, not shown, which causes a raising and lowering of the cross-beam 20 in conjunction with a lifting cylinder 24.
  • the crossbeam along the axis A raised or lowered in the direction of the double arrow X.
  • the cross-beam 20 When in the Fig. 1 shown position, the cross-beam 20 is in an upper position corresponding to the loading and unloading position, that is, from the position shown, the cross-beam 20 can be moved down.
  • a chuck 28 is mounted at the lower end of a shaft 26 guided in a shaft, which serves for fastening a workpiece, such as a rim F.
  • the shaft 27 is in this case attached to a transmission 30, which in Fig. 2 is shown enlarged.
  • Fig. 2 clarified, is on the crossbeam 20 at her in Fig. 2 mounted on the right end of a first drive motor 32, whose axis of rotation is vertical and which drives a arranged in the cross-beam 20 belt drive 40, a hollow shaft 42 which rotates about a vertical axis of rotation C.
  • the hollow shaft 42 extends down through the crossbar 20 and further through a two-piece turntable 44, the upper half 46 is screwed to the crossbeam 20 and the lower half 48 is rotatable about a ball bearing 46 relative to the upper half.
  • the hollow shaft 42 is screwed at its lower end to the lower half 48 of the turntable 44, so that upon rotation of the hollow shaft 42 about the axis C, the lower half 48 of the turntable 44 rotates together with the hollow shaft 42.
  • a ball bearing 50 is provided in the upper half of the turntable 44.
  • another ball bearing 52nd is located between the upper half 46 and the lower half 48 of the turntable 44.
  • the shaft 26 is mounted via a flange 54 eccentrically on the underside of the lower half 48 of the turntable 44, such that the shaft 26, the shaft 27 and the chuck 28 attached thereto rotate along an orbital path when the drive 32 is actuated.
  • the hollow shaft 42 is rotated via the belt drive 40 in rotation and rotates according to the lower half 48 of the turntable 52 and thus also the flange housing 54 and the attached shaft 26 with the shaft 27 disposed therein.
  • a further drive motor 56 is provided at the outer end of the crossbeam 20, which drives a rotating about the axis of rotation C vertical shaft 58 which extends through the hollow shaft 42.
  • the shaft 58 extends along the axis C through the upper and the lower half of the turntable 44 and is connected at its lower end with a gear 60 which meshes with another gear 62, which is rotatably mounted in the shaft 26 shaft 27 communicates.
  • the chuck 28 with the aid of the second drive motor 56, independent of the orbital motion and independent of a drive of the first drive motor 32 to rotate about its own vertical center axis B.
  • the drive 22 causes the oscillating movement of the rim F along the axis A in the direction of the double arrow X and the drive motor 32 causes the orbital movement about the axis C while the drive motor 56 causes the rotation of the rim F about its central axis B.

  • the drive 32 can be controlled so that the workpiece F moves along an orbital path in a clockwise direction within the container 12, while it rotates counterclockwise around its own axis of symmetry B.
  • the effective input speed can be calculated from the difference between the orbital speed and the spindle speed.
  • the orbital drive 32 is preferably adjustable between about 30 and 130 U / min, while the spindle drive 56 is preferably adjustable from about 40 to 200 U / min.
