Description

Technical Field

[0001] The utility model relates to the technical field of precision machining machine tools, in particular to a device for testing the parallelism accuracy of guide rails of heavy machine tools. Background Art

[0002] In machine tools that use rolling-sliding composite or static pressure as the machine tool guideway type, the straightness, coordinate accuracy, and dynamic response characteristics of the machine tool feed direction are not only affected by the drive mode and guideway type but also by the geometric accuracy of the guideway itself. In the actual bed guideway geometric accuracy inspection process, the straightness inspection can be carried out by autocollimator and other methods, but the transition reference inspection method has always been used for the mutual parallelism inspection between the lateral guides. This method not only has a large measurement error for machine tools with a large guideway length, but the transition reference will move and produce errors, and the measurement accuracy reliability is low, making the device measurement inconvenient.
