Problems solved by technology

The resulting equipment costs are acceptable for large batches (that is to say for a large number of identical crankshafts following each other) to be machined; Between, the device cost is unfavorable and results in a significant portion of non-productive additional operating time

Embodiment Construction

[0027] figure 1 and 2 An embodiment of a finishing device is shown from a different angle and is generally designated 10 . The finishing device 10 is used for finishing a thrust bearing surface of a workpiece 12 , which is configured in particular as a crankshaft. The workpiece 12 has an axis 14 . During machining of the workpiece 12 , it is driven by a schematically illustrated rotary drive 16 such that the workpiece 12 rotates about the workpiece axis 14 .

[0028] The workpiece 12 has at least one, preferably two thrust bearing surfaces 18 and 20 to be machined. Thrust bearing surfaces 18 and 20 together form a crankshaft flange bearing for axially supporting the crankshaft when it is installed in the internal combustion engine.

[0029] The finishing device 10 is arranged on a known and not shown frame 22 . The finishing device 10 is here fixed to a machine frame 22 or driven to oscillate along an oscillating axis 26 by a known and schematically shown oscillating driv...

Abstract

The invention relates to a finishing device (10) for machining shaft axial bearings, in particular crankshaft flange bearings, comprising a retainer (28) which is arranged or can be arranged on a machine frame (22), on which retainer a machining unit (42) comprising a finishing tool (56) is moveably mounted, wherein a movement of the machining unit (42) is associated with an adjustment of a diameter of a shaft axial bearing to be processed by means of the finishing tool (46), wherein a motorized drive unit (62) which drives the processing unit (42) along an adjustment axis (74) is provided for moving the processing unit (42). The invention further relates to a method for machining shaft axial bearings.

Description

technical field [0001] The invention relates to a finishing device for machining shaft thrust bearings, especially crankshaft flange bearings, which device comprises a holder arranged or capable of being arranged on a machine A machining unit comprising a finishing tool is mounted, wherein the movement of the machining unit is associated with the adjustment of the diameter of the shaft thrust bearing to be machined by the finishing tool. Background technique [0002] The aforementioned finishing device is used, for example, for machining crankshaft flange bearings. These bearings have mutually facing axial bearing surfaces which adjoin the circumferential surface of the crankshaft flange bearing radially inwardly. In order to accommodate at least the inner diameter of the thrust bearing surface, the position of the finishing tool needs to be adjusted such that the finishing tool cannot go below its minimum diameter. For this purpose, the machining unit with the finishing t...
