Description

Technical Field

[0002] The straightness of the guide rail is the basic accuracy of the precision of various machine tools, and the straightness of the guide rail has a direct impact on the precision of many machine tools. Once the guide rail is subjected to uneven force during the production process or is subjected to uneven heat during the heat treatment process, it will cause the guide rail to bend locally, thereby destroying the straightness of the guide rail. In this case, it is necessary to calibrate the bent guide rail with unqualified straightness, which requires a device that can calibrate the straightness of the guide rail. In the existing technology, the guide rail straightness detection device is generally arranged adjacent to the guide rail in parallel. Not only does it need to correct the straightness of the guide rail, but it also needs to pre-measure the straightness of the guide rail straightness detection device. Multiple measurements are required, the operation is cumbersome, and stable and continuous measurement cannot be achieved over the entire length of the guide rail, which limits the scope of use of the guide rail straightness detection device.
