Problems solved by technology

As a result, although the finishing belt can be brought into contact over a large contact surface, the available pressing force is relatively low and unevenly distributed along the partial circumference

Embodiment Construction

[0037] An embodiment of the device, indicated generally at 10 , is used for belt finishing, such as a crankshaft workpiece 12 . The workpiece 12 has a workpiece axis 14 and a workpiece surface 16 to be finished. For machining the workpiece surface 16 , a finishing belt 18 is provided which rests against the workpiece surface 16 along a part of its circumference. The workpiece surface 16 is, for example, a journal of a crankshaft.

[0038] During finishing machining of the workpiece 12 , the workpiece is driven by known and therefore not shown individual drives. The rotary drive moves the workpiece 12 in rotation about the workpiece axis 14 . The pivot drive moves the workpiece 12 in a pivoting motion parallel to the workpiece axis 14 in opposite directions. Through a combination of rotational and oscillating movements, the abrasive contact of the finishing belt 18 with the front side of the finishing belt with the workpiece surface 16 produces the properties of the finishin...

Abstract

A device for finishing a workpiece includes two pressing elements and a holding apparatus for holding the pressing elements. A finishing band is pressable against a workpiece surface to be finished. A flexurally resilient intermediate element is disposed so as to transmit a pressing force to the finishing band by means of a force-receiving surface and by means of a force-transmitting surface. The intermediate element or a plurality of them is configured to transmit pressing forces, which are offset relative to one another in a circumferential direction of the workpiece surface, to the finishing band. The force-transmitting surfaces of the intermediate element or the plurality of them are oriented in a substantially V-shaped manner relative to one another, and are substantially planar in an undeformed initial state and have a curvature in a same direction as the workpiece surface when there is a pressing force.

Description

technical field [0001] The invention relates to a device for belt-type finishing of workpieces, said device comprising a holding device for holding at least one press piece and comprising a finishing belt capable of being moved by the press piece at the level of the press piece The belt is pressed against the workpiece surface to be finished. Background technique [0002] Finishing of workpieces is a method for surface processing of workpieces, also known as "superfinishing" or "ultra-finishing". In this method, an abrasive finishing tool, such as a finishing stone or a finishing belt, is pressed against the surface of the workpiece to be machined. Here, the workpiece surface to be machined rotates. This rotation of the workpiece surface to be machined is superimposed with a pivoting movement, wherein the finishing tool and the workpiece surface to be machined are moved relative to each other in a direction parallel to the axis of rotation. [0003] Devices of the aforeme...
