Problems solved by technology

[0005] Although this method of directly measuring the outer cone surface (or inner cone surface, or the outer circle of the inspection rod) of the main shaft is simple, the deviation value measured in this way, especially the radial runout, includes the position deviation (the geometric axis of the main shaft and its rotation axis Miscoincidence) and the runout deviation of the outer cone surface of the spindle (or the inner cone surface, or the outer circle of the test rod) is not the radial runout of the rotation center of the spindle system when the spindle is actually working, so it cannot reflect the real spindle rotation accuracy , especially the true accuracy of the center of rotation of the spindle of a precision machine tool

Abstract

The invention discloses a detection method and a detection device for rotation precision of a precision machine tool spindle. The detection device for the rotation precision of the precision machine tool spindle comprises a supporting disc, a fine adjustment screw, an adjustment screw, a connection screw, a precision inductance probe, a round magnet, a precision steel ball, a supporting body, a circular ring and a high-precision length displayer. According to the detection device for the rotation precision of the precision machine tool spindle, the precision detection device is arranged at the front end of the machine tool spindle, performs detection through correction, is simple in structure, high in reliability and high in operability and can reflect the rotation precision of the precision machine tool spindle more accurately and more truly.

Description

technical field [0001] The invention relates to the technical field of mechanical engineering, in particular to a detection method and a detection device for the rotation accuracy of a spindle of a precision machine tool. Background technique [0002] With the development of machine tools towards high speed and high precision, the precision machine tool spindle, which is one of the key components of machine tools, is also developing rapidly. The rotation accuracy of the precision machine tool spindle is the basic requirement for the working performance of the high-speed precision machine tool spindle system. In the manufacturing and application process of the precision machine tool spindle, measuring or checking its rotation accuracy is a key link, and it is a necessary condition to ensure the rotation accuracy of the precision machine tool spindle system. [0003] At present, my country has formulated and implemented the national standard for machine tool inspection gene...
