Length measurement instrument for a machine tool, comprises a housing that also forms the guide rail for a scanning unit carriage, with the guide rail aligned parallel to a machine tool guide using flexible elements

摘要

Encapsulated length measurement instrument has a housing (3) that forms the guide rail (31) for a guide carriage (10) on which a scanning unit (2) is mounted. The scanning unit is rigidly mounted in all coordinate directions, X, Y, Z, on the guide rail. The rails is rigidly attached to the machine component on which measurements are to be made. Incorrect alignment of the housing relative to a machine guide (12) is corrected using flexible coupling elements (51, 61) between the housing and mounting elements (5, 6) or by use of a bendable housing.
