Definitions
- the invention relates to a device in the preamble of protection claim 1 Art.
- Such a device has become known from EP 0 161 748 B1 (see the exemplary embodiment according to FIG. 4 and the description, column 5, line 53).
- the pressure jaw (referred to there as an insert), as indicated by the arrow B in FIG. 5, can be tilted relative to an axis parallel to the axis of rotation of the workpiece.
- the pressure jaw is penetrated by a pin which is arranged in the carrier.
- the object of the invention is such a device to provide, at the same time the bracket and the Replacing the pressure jaws is particularly easy.
- the exemplary embodiment has two holding arms 1, 2, the lower of which can be moved towards and away from each other are. On them are carrier 3 (hereinafter as Quick-change adapter) and 6 arranged that Pressure jaws 4 (hereinafter referred to as processing bowl designated) and wear 7. These surround the one to be processed Surface of a workpiece 10, e.g. the connecting rod bearing one Crankshaft or camshaft.
- the workpiece 10 is through Devices (not shown) rotated. Unless it is doing z. B. is a connecting rod bearing of a crankshaft, axis of rotation A also performs a circular movement.
- the holding arms 1, 2 are movable arranged on a device, not shown, it allowed them to follow the movement of axis A.
- the Quick-change adapter 3 is, as from FIG. 2 and FIG. 4 can be seen on its inner contour with a covering 3 ' Mistake.
- This covering consists of, for example Polyurethane or Vulkollan, i.e. a plastic that is at least somewhat compressible elastically.
- the covering 3 ' stands, as exaggerated from Figure 2, laterally something about the side surfaces 19, 20 of Quick-change adapter 3 in front, so that there is a T-shape results.
- This design of the quick-change adapter 3 enables it, the processing shell 4 in cross section U-shaped in the manner shown in FIG. 1 and FIG Attach quick-change adapter 3.
- the Processing tray 4 is in the preamble of claim 1 Called pressure jaws.
- the covering 3 'of the narrow The end faces are slightly compressed elastically so that due to the resulting compression and frictional force between the lateral front edges of the covering 3 'and the Inner surface of the processing shell 4 the latter on the Quick-change adapter 3 is held sufficiently firmly. This makes the replacement of the processing trays 3 extreme simplified.
- the processing tray 4 can be due to this storage the quick-change adapter 3 their location the location of the Adjust workpiece 10 and different diameters.
- the covering 3 ' is compressed accordingly or relieved.
- the formation of the U-shape of one part (the Machining shell 4) and the T-shape of the other part (Quick-change adapter 3 with pad 3 ') can also regarding of the components be reversed so that the processing tray T-shaped and the quick-change adapter U-shaped are trained and inserted into each other in the same way are.
- the working surface 4 ' is the surface of the Processing tray 4, with which it on the belt 15 (see. Figure 1) presses. It can also increase the frictional force between her and the tape 15 to increase, with a layer, e.g. made of a ceramic material or Vulkollan, be provided.
- the lower end of the holding arm 2 holds the carrier 6, in the dovetail pressure jaws 7 are inserted, the also press on tape 15.
- the Bracket 2 can also be the system at the bottom of the holding arm 1 is shown, or any other System for pressing the band 15 may be provided.
- the grinding belt 15 is held over belt guide bolts 11 to 14 performed in the manner shown.
- the band is one such as it e.g. in the prospectus of 3M described and produced by this.
- the Holding arms 1, 2 make in addition to the movements mentioned a back and forth movement perpendicular to the image plane and take over the pressure jaws 7 and Processing shell 4 with the grinding belt 15.
- the workpiece 10 is rotated.
- the combination of these and movement of the grinding belt 15 perpendicular to Image plane with the rotational movement of the workpiece 10 results the desired fine machining.
- the means for Band guides are from the above Known in the art, so that their further description will be omitted can.
- Pins 16, 17 are on the interchangeable adapter 3 provided with the stop or guide surfaces 18, 19th the processing tray 4 (see FIG. 4) interact to to achieve that the processing tray 4 on the Interchangeable adapter 3 when inserted in the correct position slides.
- the processing scarf has 2 openings 20, 21 which with corresponding openings 22, 23 in Quick-change adapter 3, the latter a little have a larger diameter, are aligned. In the openings 20, 23 you can use ball snappers that are in the openings 21, 22 releasably intervene to determine the Machining trays 4 on the quick-change adapter without functionally significant impairment of their mobility to improve.
- Devices 24 and 25 are also shown in FIGS. 3 and 4 apparent that serve the location of the quick-change adapter 3 at the end of the holding arm 1 or Processing tray 4 on the quick-change adapter 3 to be determined.
