Problems solved by technology

A disadvantage of the known device is that the thread length measured along the axis of rotation of the workpiece is limited, wherein along the thread length the inner surface can be finished and the thread length is preset by the length of the U-shaped tool holder
Furthermore, it is disadvantageous that the maximum possible oscillation angle of the tool holder is limited as a function of the plunging depth of the finishing tool measured along the axis of rotation of the workpiece

Embodiment Construction

[0033] figure 1 An embodiment of an apparatus 10 for finishing an interior surface 12 of a workpiece 14 is shown.

[0034] The inner surface 12 is in particular the raceway of the ball screw drive. The inner surface 12 is part circular or arcuate in profile. The inner surface 12 extends in a threaded form (helical form) along at least a portion of the length of the workpiece 14 measured parallel to the workpiece axis 16 .

[0035] The device 10 comprises a workpiece holder 18 which can be designed, for example, as a chuck 20 . The workpiece holder 18 is connected to a rotary drive 22 by means of which the workpiece holder 18 and the workpiece 14 are driven rotatably about an axis of rotation 24 .

[0036] The device 10 also comprises a linear drive 26 for driving the slide 28 in a direction parallel to the axis of rotation 24 , for example in a direction 30 in the direction of the workpiece holder 18 or in the opposite direction.

[0037]The slide 28 serves to fix an oscil...

Abstract

The invention relates to a device (10) for the finishing machining of an internal face of a workpiece (14), such as the track of a ball screw. The device includes a workpiece holder (18) and a finishing tool (46) held on a finishing tool holder (36). A rotary drive (22) is provided, by which the workpiece holder (18) and the finishing tool (46) are rotationally driven relative to one another about a rotational axis (24). A linear drive (26) is provided, by which the finishing tool (46) held on the finishing tool holder (36) and the workpiece holder (18) is driven in a translatory manner relative to one another along the rotational axis (24). An oscillating drive (32) is provided, by which the finishing tool (46) held on the finishing tool holder (36) and the workpiece holder (18) is driven in an oscillating manner relative to one another in the direction parallel to the rotational axis (24) and wherein the finishing tool (46) is pivotably held on the finishing tool holder (36) about a pivot axis (44). The invention also relates to a method for the finishing machining of an internal face of a workpiece (14).

Description

technical field [0001] The invention relates to a device for finishing the inner surface of a workpiece, in particular a raceway of a ball screw drive, the device comprising a workpiece holder and a finishing tool held on the finishing tool holder, in which a rotary drive is arranged , the workpiece holder and the finishing tool are driven by a rotary drive device in a manner capable of rotating relative to each other around a rotation axis, wherein a linear drive device is provided, and the finishing tool held on the finishing tool holder and the workpiece holder can be moved along the They are driven by linear drives in a linear motion relative to each other along the axes of rotation.
