Description
Technical Field
The invention relates to the technical field of detection equipment, in particular to a novel rotor flatness rapid detection tool.
Background
Flatness refers to the deviation of the height of a macro relief of a substrate from an ideal plane. The tolerance zone is the area between two parallel planes at a distance of the tolerance value t. The flatness belongs to the shape error in the form and position errors. The following methods are commonly used for measuring flatness error:
a flat crystal interference method: the working surface of the optical flat crystal is used for generating an ideal plane, and the flatness error value of the measured surface is directly determined according to the bending degree of the interference fringes. The method is mainly used for measuring the flatness error of a small plane, such as a working surface of a gauge and a measuring surface of a measuring head of a micrometer.
The plane is composed of straight lines, so that a straight ruler method, an optical alignment method, an optical auto-alignment method, a gravity method and the like in straightness measurement are also suitable for measuring flatness errors. When measuring flatness, firstly measuring the straightness of several sections, and then using graphic method or calculation method to process data according to the value of each measuring point and flatness tolerance band definition (see form and position tolerance) to obtain flatness error. The plane error is also measured by the optical wave interference method and the plate painting method.
A tabulation measurement method comprises the following steps: the method is to put the measured part and the micrometer on the standard flat plate, and to measure the part point by point or along several straight lines by the micrometer along the actual surface with the standard flat plate as the measuring reference surface. The method for measuring the table is divided into a three-point method and a diagonal method according to an evaluation reference plane: the three-point method is characterized in that an ideal plane determined by three points which are farthest away on a measured actual surface is used as an evaluation reference plane, and the three points which are farthest away on the measured actual surface are adjusted to be as high as a standard flat plate in actual measurement; in the diagonal method, four corners on the actual surface are adjusted to be equal to each other in height according to diagonals. Then, a micrometer is used for measurement, and the maximum variation measured by the micrometer on the whole actual surface is the flatness error of the actual surface.
Liquid level method: the level method uses a liquid level, which is constituted by a liquid level in a "communicating tank", as a measurement reference level, and then measures the liquid level with a sensor. The method is mainly used for measuring the flatness error of a large plane.
The existing equipment for detecting the flatness of the rotor is high in manufacturing cost, and the detection method is complex, so that the production cost is increased.
