Problems solved by technology

This imposes a burden on the precision of the finishing process and also causes the oscillation frequency of the fine tool to be limited to relatively low values, so that the machining time of the workpiece is prolonged

Embodiment Construction

[0029] A device for finishing workpieces is indicated generally by the reference numeral 10 in the drawing.

[0030] The device 10 has a support body 12 which, in particular with its upper end with respect to the direction of gravity, can be fastened, for example, to a cross carriage or a robot arm and can thus be freely positioned in space. Guide elements 14 , in particular in the form of rollers 16 , 18 , 20 , are arranged on the support body 12 , in particular at the lower end of the support body 12 with respect to the direction of gravity. The rollers 16 , 18 , 20 are fixed in position relative to the support body 12 , but are arranged rotatably about axes parallel to one another.

[0031] The rollers 16 and 18 are arranged radially on the outside with respect to the curved rail 22 and the roller 20 is arranged radially inward with respect to the curved rail 22 . The curved rails are accommodated between the rails 16 , 18 and 20 without play.

[0032] The curved rail 22 ...

Abstract

The invention relates to a device (10) for finishing a surface of a bent workpiece. The device has a driving device (52) generating oscillating pivoting movement of a finishing tool holder (26) to hold a finishing tool (28). The holder is guided at a guiding device (54) in a pivotable manner around a virtual pivot axis, where the guiding device (54) defines a curved guide track (24).

Description

technical field [0001] The invention relates to an apparatus for finishing the surface of a curved workpiece comprising drive means for generating an oscillating pivotal movement of a fine tool holder for holding a fine tool. Background technique [0002] Finishing of tools is a method for surface processing of workpieces, also known as "superfinishing" or "finest machining method". In this method, an abrasive fine tool, such as a lapping stone or lapping belt, is pressed onto the workpiece surface to be machined. Here, the workpiece surface to be machined rotates. The rotation of the workpiece surface to be machined is superimposed with an oscillating movement, wherein the fine tool and the workpiece surface to be machined move relative to each other in a direction parallel or oblique to the axis of rotation. [0003] The finishing of the workpiece is also used for the machining of the surface of the workpiece curved on the profile. Examples of workpieces with such workp...
