Shaft circle run-out detection device and method

Abstract

The invention discloses a shaft circle run-out detection device and method, and the device comprises a detection assembly which is in contact with the surface of a shaft and detects the circle run-out of the shaft when the shaft rotates, and the detection device comprises a pedestal, a first part which is disposed on the pedestal and is used for supporting one end of the shaft, and a second part which is disposed on the pedestal and is used for supporting the other end of the shaft. The first part is provided with a driving piece for driving the shaft to rotate on the first part and the second part; and the detection assembly is provided with a flushing mechanism for flushing the axial surface and an air injection mechanism for injecting air to the axial surface at high pressure. According to the invention, the water flushing mechanism or the air injection mechanism is utilized to clean the surface of the detected shaft simultaneously or separately to remove fine particles on the axial surface, so that a new axial surface is obtained; and then the new axial surface is measured through the detection assembly to obtain a measurement value. According to the invention, the flushing mechanism and the air injection mechanism are integrally mounted on the instrument for detecting the shaft parts, so that the use is convenient, and the effects of quickly cleaning the local surfaces of the shaft parts and accurately measuring the local surfaces of the shaft parts are improved.

Description

technical field [0001] The invention relates to the technical field of shaft machining, in particular to a shaft circular runout detection device. Background technique [0002] As an important rotating part inside the motor, the machining accuracy of the shaft has a great influence on the vibration, noise and service life of the motor. Among them, the circular runout of each surface on the rotating shaft is an important index to measure the machining accuracy and coaxiality. The current detection method is measured by a lathe; the measurement point is to measure the circular runout of the shaft, the diameter of the shaft, and the length of the shaft. The current method of detecting the circular runout of the axis is to install the axis on the machine tool and then fix one end of the axis to be detected by the chuck assembly, while the other end is fixed with the top needle to the other end of the axis to be detected, so that the detection exists Small particles, such as iro...
