Description
Technical Field

Background
In machining, in order to detect whether a machined product meets the use requirement, an indicator is required, and in particular, for a precision product, a precision detection indicator is required. The dial indicator and the dial indicator are commonly used precise indicator indicators, and the dial indicator are adopted, so that not only can the relative value be measured, but also the absolute value can be measured, and the dial indicator is mainly used for measuring shape and position errors, and also can be used for precise alignment when a workpiece is installed on a machine tool. One of the most important applications of the dial indicator is to measure shape and position errors and other mechanical measurements, such as roundness, runout, flatness, parallelism, straightness, etc. In the daily use process, the dial indicator and the dial indicator need to be verified in order to measure accurate and effective data. The existing verification equipment is high in price, complex in operation and troublesome in detection process, and the detection efficiency is low.
The currently used dial indicator or dial indicator verification instrument is generally a dial indicator or dial indicator verification instrument, a 5-index micrometer mechanism is adopted, namely a 5-index plate device is arranged on a differential sleeve of a micrometer gauge of the verification instrument, the displacement of a micrometer screw rod is equal when the micrometer gauge is rotated for 72 degrees, and therefore whether the indication value of a detected meter is identical with the indication value of the micrometer mechanism or not is observed, and if the indication value is not identical, the error exists in the detected indication value is indicated. As to what the error is, it is estimated by the certification personnel from the position of the pointer at that time of the dial indicator or dial indicator. Since there is parallax at the time of visual observation, an error in the display value of the inspected table cannot be correctly read. With the development of technology, semi-automatic or full-automatic verification instruments are also used for verification, but the cost is high.
Equidistant spirals, i.e. archimedes spirals, which are curves that rotate around some fixed point or axis and continuously contract or expand, archimedes spirals are two-dimensional spirals. In the "theory spiral", archimedes gives the following definition: while a point P moves at a constant velocity along the moving ray OP, the ray rotates at an equal angular velocity around a point O, and the locus of the point P is called an archimedes spiral. Its polar equation is r=aθ. The distance of each arm of this spiral is always equal to 2pi.a. Whereas the standard polar equation for archimedes' spiral is: r (θ) =a+b (θ), where: b-Archimedes spiral coefficient mm/°, representing the amount of increase (or decrease) in pole diameter per 1 degree of rotation; θ—polar angle in degrees, representing the total number of degrees the archimedes spiral turns through; a-the polar diameter when θ=0°, in mm.
