Description

Roundness testing device
Technical Field
The utility model relates to a roundness testing field specifically is a roundness testing device.
Background
Roundness measurement is a technical method of measuring a circular surface of a workpiece to determine a difference between the circular surface and a true circle. The method specifically includes three categories: (1) and (4) comparing and checking. The measured circle profile is compared to a standard circle (e.g., standard circle figure, hemisphere, disk, etc.) to identify the difference therebetween. Projector comparison and micrometer comparison are commonly used. (2) And measuring characteristic parameters. The roundness error is approximately expressed by the difference between the respective quantities through a plurality of measurements of certain characteristic values of the round surface. Commonly used are: two-point methods, three-point methods (V-block support measurements), and two-point and three-point combination methods. This method is simple and easy to implement, but has poor accuracy. (3) Coordinate measurement method. And is divided into a polar coordinate method and a rectangular coordinate method.
The commonly used polar coordinate method is that the circle track drawn by a certain point when the precise rotating shaft rotates is compared with the circle to be measured, the radius difference between the circle track and the circle to be measured is measured by a sensor, and the roundness error value can be obtained after the record and the operation of a microprocessor, and the outline graph of the circle to be measured can also be drawn by a recorder. The measuring instrument developed in this way is called a roundness measuring instrument. The method is characterized in that coordinate values x and y of a plurality of points on a measured circle are measured on a three-coordinate measuring machine according to a pre-selected rectangular coordinate system, and the roundness error of the measured circle is calculated by an electronic computer according to a selected roundness error evaluation method. The roundness error evaluation method comprises the following steps: the minimum area method, the least squares method, the minimum circumcircle method, and the minimum inscribed circle method. The common characteristics of each method are as follows: two ideal circles are used for containing the actual contour of the measured circle; the difference is as follows: the criteria for containment vary.
