The invention discloses an ultra-precision fly-cutting machine tool spindle and guide rail rigidity detection device and detection method, which belong to the technical field of machine tool performance detection. The invention solves the problem that the prior art cannot realize the accurate detection of the rigidity of the ultra-precision static pressure main shaft and the guide rail. The first reference plate is fixed with a force sensor, a cylinder and a centering strut in sequence from bottom to top, and a centering hole is provided at the bottom of the support plate, and the centering hole is coaxially arranged with the main shaft, and the centering strut The top of the rod is matched with the centering hole, a number of guide rail displacement sensors are arranged above the first reference plate, a number of spindle displacement sensors are arranged above the second reference plate, and some of the guide rail displacement sensors and some spindle displacement sensors are arranged around the main shaft respectively. The axes are evenly distributed, several spindle displacement sensors are respectively connected to the spindle displacement signal collector through wires, several guide rail displacement sensors are respectively connected to the guide rail displacement signal collector through wires, and the force sensors are connected to the force signal collector through wires.
Description
technical field [0001] The invention relates to an ultra-precision fly-cutting machine tool spindle and guide rail rigidity detection device and detection method, belonging to the technical field of machine tool performance detection. Background technique [0002] With the rapid development of modern science and technology, especially the rapid advancement of cutting-edge science and technology such as aviation, aerospace, national defense, and military industry, these industries have higher and higher requirements for product stability and performance. The typical example is laser nuclear fusion. The KDP crystal device is widely used in the system. Due to the characteristics of soft, brittle and deliquescent crystals, traditional optical processing methods such as grinding and polishing cannot be used for ultra-precision processing of large-diameter KDP crystals. Currently, single-point diamond flying knife cutting is the The main means to realize the final processing of KD...
