The utility model is used for the test of static pressure main shaft gyration error through the screw of adjusting the base tray, can reduce to press from both sides the assembly error between structure and the main shaft, and convenient operation is with low costs.
Description
Technical field
The utility model relates to a kind of optical flat clamping structure for spindle rotation error testing arrangement, belongs to mechanical clamp technology ultra precise measurement field.
Background technology
Machine tool chief axis is the critical component of lathe, and the rotating accuracy of machine tool chief axis determines the machining accuracy of lathe, and the machining accuracy of lathe is higher, and the proportion that Rotary Precision of Spindle of Machine Tools occupies is larger; By testing the turn error of main shaft, the shape and the machining accuracy improving lathe etc. on the source of spindle rotation error, prediction workpiece to be processed surface can be found.
At present, usually by high precision electro, perhaps inductance displacement sensor, standard ball and computer etc. form spindle rotation error test macro, the performance of sensor, the machining accuracy of standard ball determine the measuring accuracy of this kind of test macro, but this kind of measuring system sensor is subject to the interference of environment, affects final spindle rotation error test result.Therefore, propose a kind of spindle rotation error test macro based on dynamic interferometer, this kind of method of testing dynamic interferometer is as measuring transducer, optical flat is as detection reference, optical flat three-dimensional surface shape is obtained by interferometer Real-time Collection, obtain spindle rotation error by analyzing optical flat topographical information, optical flat is high-accuracy optical element.Therefore, the installation way of optical flat affects the measurement result of main shaft gyration test.
Conventional optical flat detection system is made up of soft hardware equipment such as laser interferometer, optical flat clamping structure, computer and image processing softwares, because optical flat is high-accuracy optical element, slightly External Force Acting all can cause the change of optical flat surface three dimension structure on optical flat surface, even the gravity of optical flat self all can cause the change of optical flat three-dimensional surface shape, therefore when assembling optical flat to be detected, avoid generation clamping structure and optical flat to produce clamping stress, in order to avoid the three-dimensional appearance on the stress rupture optical flat surface produced as far as possible; So when optical flat is when being in turning course, the measurement that new disturbing factor affects optical flat three-dimensional surface shape will be introduced.According to the clamping structure of existing optical flat, not yet find be suitable for and the special fixture detecting optical flat flatness in dynamic rotation process.Therefore, design a kind of optical flat clamping structure for turn error testing arrangement herein, this clamping structure has the features such as simple, the easy to operate and clamping stress of structure is little.
Summary of the invention
