Problems solved by technology
The study found that [two basic problems in the three-point method error separation technology], even if there is a difference of 0.1° between the actual installation angle of the sensor probe and the theoretical installation angle, the final measured rotation error cannot be successfully separated
However, the existing sensor installation and arrangement methods are difficult to ensure that the actual installation angle of the sensor probe is consistent with the theoretical installation angle, and the installation process is extremely cumbersome

The present invention discloses a spindle rotation error measurement apparatus. The apparatus includes a spindle box body, a spindle fixing sleeve, a coupling disc, and a base fixing disc. One end ofthe spindle fixing sleeve is mounted on the spindle box body, and the other end is connected to the coupling disc. The base fixing disc is fixed on the coupling disc, a supporting base is pressed in agroove of the base fixing disc by using a pressing plate, an indexing disc is fixed on the base fixing disc, and a sensor probe holder is pressed on the indexing disc and is connected to the supporting base. A shank is connected to a rotor in the spindle box body. The sensor probe holder has a mounting hole perpendicular to an axial direction of a spindle, and a sensor probe is mounted in the mounting hole on the sensor probe holder. The apparatus has a simple structure and is installed with convenience. A position of the sensor probe holder is adjusted on the indexing disc, and a relative angle of the sensor probe surrounding the shank is determined, so that a spindle rotation error can be accurately measured. At the same time, the apparatus can not only measure a rotation error of idlerotation of the spindle, and can also measure a rotation error in a cutting state.
Description
technical field [0001] The invention relates to a spindle rotation error measurement device. The device can determine the installation angle of the sensor probe through the indexing plate installed on the spindle, and use the high-precision cylindrical surface on the tool handle to replace the traditional standard rod or standard ball. It is convenient to test the rotation accuracy of the spindle under idling and cutting conditions. Background technique [0002] Machine tools are developing in the direction of high speed, high efficiency and high precision. As an important functional part of the machine tool, the rotation accuracy of the spindle is one of the important indicators to measure the performance of the CNC machine tool. The large rotation error of the spindle will not only increase the wear of the tool, but also directly affect the processing quality of the workpiece, especially in high-speed machining. The dynamic load of the machine tool seriously affects the s...
