Embodiment Construction

[0026] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

[0027] A method for detecting the verticality of the rotating shaft in this embodiment, the I-axis and the II-axis in the present invention are any two vertical axes on the turntable, and there is no order, and can be used for both two-axis turntables and three-axis or more axis turntables.

[0028] First, grind two mandrels, and install the mandrels on both sides of the turntable II shaft as the lead-out end of II;

[0029] Secondly, use a screw micrometer to measure the roundness error of the lead-out ends on both sides of the turntable II axis, and record the data;

[0030] Then, use a dial indicator to measure the circular runout of the turntable II axis, and record the data; rotate the turntable I axis, use a dial indicator to measure the change value of the lead-out mandrel on both sides of the turntable II axis, and record the...

Abstract

The invention discloses a method and equipment for detecting the verticality of a rotating shaft. The method comprises the following steps of: firstly, grinding two central spindles, installing the central spindles on both sides of a shaft II of a rotary table as leading-out ends of the shaft II; secondly, measuring deviation from circular form of the leading-out ends on both sides of the shaft II of the rotary table by using a micrometer caliper, and recording data; then, measuring circular run-out of the shaft II of the rotary table by using a dial indicator, and recording data; rotating a shaft I of the rotary table, measuring change value of the leading-out central spindles on both sides of the shaft II of the rotary table by using the dial indicator, and then recording data; finally, performing angle conversion according to recorded data so as to obtain the verticality of the two shafts. The instrument is simple and reliable; the method is quick and accurate in method; the influence of environment on detection is less; the device can be used for detecting the verticality of two shafts of various types of equipment, and has good adaptability.

Description

technical field [0001] The invention belongs to the field of electromechanical equipment, and in particular relates to a method and equipment for detecting the verticality of a rotating shaft. Background technique [0002] Perpendicularity, is a positional tolerance. According to the difference between the reference datum and the measured element, the perpendicularity can be divided into four categories: line-to-datum line, line-to-datum plane, line-to-datum system, perpendicularity to the datum line and to the datum plane. The rotation axes of the turntable are generally required to be perpendicular to each other, and the verticality error is an important indicator for evaluating the accuracy of the turntable system. [0003] The shafting installation of the turntable is a process of repeated installation and adjustment, which requires multiple inspections of the verticality error. At present, there are many methods for detecting the verticality of the turntable shaft sys...
