Embodiment Construction

[0034] In the following figures, corresponding parts and elements have the same reference numerals. For the sake of clarity, not all reference numbers are shown in all figures.

[0035] In the figures, an apparatus generally indicated by reference numeral 10 is shown. The apparatus 10 is used for honing a bore 12 in a workpiece 14; in this example, the workpiece 14 is formed by a crankcase 14 and the bore 12 is formed by a crank bore 12 in the crankcase 14 (see image 3 ). The crankcase 14 is designed, for example, as an engine block and has, in addition to the crank bore 12, four cylinder bores 16 oriented orthogonally to the crank bore 12 (see image 3 ).

[0036] In the figure, a coordinate system is also shown, with axes (X, Y, Z) orthogonal to each other.

[0037] The device 10 includes a device base 18 which, by way of example and preferably, is generally rectangular as seen in a viewing direction normal to the device base 18 (see image 3 ). The extension of the d...

Abstract

The invention relates to an apparatus (10) for honing a bore (12) in a workpiece (14), having an apparatus base (18), having a turntable (20), arranged on the apparatus base, with a plurality of workpiece receptacles (32A, 32B, 32C, 32D), having at least one loading station (38) for loading and unloading from the workpiece receptacles, having at least one honing station (42) with a horizontal honing unit (46) and with a displacement device (58) for displacing the horizontal honing unit relative to the turntable (20), and having at least one tool magazine (74) for receiving a plurality of honing spindles (50), wherein the at least one tool magazine is fixed in an immovable manner at least with respect to movements in translation, wherein the at least one tool magazine is positioned or positionable with respect to the at least one honing station such that the at least one tool magazine takes up a tool-changing position, in which relative movements, necessary for a tool change, between the at least one tool magazine and the horizontal honing unit of the at least one honing station can be provided by displacement movements of the horizontal honing unit.

Description

technical field [0001] The invention relates to a device for honing a hole in a workpiece according to the preamble of claim 1 . Background technique [0002] Such devices are known from the prior art and are used in particular for honing crank bores and camshaft bores in crankcases. [0003] Honing often requires multiple honing operations using different honing tools. For example, a first honing operation may be used to correct the diameter and dimensional accuracy of the hole, while a second honing operation may be used to smooth or otherwise topographically modify the surface, e.g., to have a desired (e.g., high or differently defined) roughness. For this purpose, devices of the type mentioned at the outset usually have a tool changing device for changing the honing tool in a particularly automated manner. The tool changing device usually includes a tool magazine for accommodating a plurality of honing tools, wherein the tool magazine can be displaced relative to the ...
