Embodiment Construction

[0037] figure 1A prior art honing device 1 is shown. The honing device 1 produces a cylindrical bore 4 with a rotationally driven honing tool 5 in a known manner, wherein the honing tool 5 performs an oscillating lift movement in addition to the rotational movement.

[0038] The honing tool 5 is thus connected to a spindle 7 which is part of a not shown honing machine and which can be moved back and forth in the direction of the longitudinal axis of the bore or the inner surface 10 to be machined by eg hydraulic or electric lift drives. Furthermore, the spindle 7 is driven in rotation about its longitudinal axis 6 by a rotary drive (not shown) in a known manner. The honing tool 5 carries a machining tool 9 embodied as a honing stone, which can be fed radially outward from a hydraulically actuated feed and can be pressed against the inner surface 10 of the conical bore 4 . The feed device can also be actuated electrically via servomotors, for example. The hydraulic actuation...

Abstract

The invention relates to a device and a method for producing a non-cylindrical inner surface (10) of a bore (4) comprising machining tools (9) which are arranged along the circumference of the bore (4) and can be radially advanced towards the inner surface (10) of the bore (4). The device comprises a primary advancing system (14) which comprises an axially movable advancing rod (13) for actuating the machining tools (9), thus exerting a primary force (FZ) onto at least one machining tool (9), the at least one machining tool (9) being radially advanceable towards the bore (4) by means of said primary force. The primary force (FZ) is dynamically superimposed with a secondary force which is generated by a secondary advancing system (16) that forms an integral unit together with the primary advancing system (14) or can be constructed in a modular manner. The secondary advancing system (16) is activated dependent on a current rotational movement and / or a stroke movement of the primary advancing system (14), a current tool position, or a specified advancing force, or the secondary advancing system is activated at a specified time. In the process, the tool is already widened by the primary advancement.

Description

technical field [0001] The invention relates to a device for producing a non-cylindrical inner surface of a hole according to the preamble of claim 1 . Furthermore, the invention relates to a method for producing a non-cylindrical inner surface of a hole according to the preamble of claim 9 and a method for operating a non-cylindrical inner surface of a hole according to the preamble of claim 13 Control equipment for fixtures on the inner surface. Background technique [0002] The device for machining a hole described above preferably, but not exclusively, relates to a device for machining a hole by honing. [0003] The hole being honed must follow a predetermined geometry very precisely. Of course, some workpieces with honed bores become non-circular during installation (mechanical prestressing) and / or during operation due to forces or through temperature-dependent deformations. This shape change is a change from an ideal cylindrical shape. In order to compensate such s...
