Problems solved by technology
However, some equipment does not require high-precision angle measurement, especially for small toothed disc mechanical devices. Due to the small internal space and compact structure, it cannot accommodate larger and high-precision angle measurement devices. In order to achieve real-time angle positioning, A simple and reliable method of angle measurement needs to be developed for these small toothed disc mechanisms

Embodiment Construction
[0020] The present invention will be described in further detail below in conjunction with the embodiments and with reference to the accompanying drawings.
[0021] A. A feedback ring 1 is installed in the upper toothed plate 32 of the toothed plate mechanism 3. The feedback ring 1 is an internal gear with several teeth on the inner wall. The top surface of each tooth of the feedback ring 1 is bright. Surface 11 and tooth root surface are both dark surfaces 12; the bottom of the feedback ring 1 is installed on the inner end surface of the upper toothed plate 32 of the toothed plate mechanism 3, and the outer ring of the feedback ring 1 is connected with KD-504 glue through set screws On the inner ring of the upper toothed plate 32, there is a gap between the outer wall of the outer ring of the feedback ring 1 and the inner wall of the inner ring of the lower toothed plate 31;
[0022] B. A reflective photoelectric switch 2 is fixed on the central axis of the feedback circle 1....

The invention discloses a feedback loop-based angle measurement method for a gear plate mechanism. The method comprises specific steps that a feedback loop is arranged inside an upper gear plate of the gear plate mechanism, and a reflective photoelectric switch is arranged on a lower gear plate of the gear plate mechanism; under control of a controller, a step motor drives the upper gear plate ofthe gear plate mechanism to raise, the other step motor drives the upper gear plate of the gear plate mechanism to rotate, and the feedback loop rotates along the upper gear plate of the gear plate mechanism, so that light emitted from an emitter of the reflective photoelectric switch is switched to a dark side of a tooth root from the bright side of a tooth top; and an electric signal received bya receiver in the reflective photoelectric switch changes in brightness, the changing electric signal is transmitted to the controller, and the controller monitors changes of the electric signal of the reflective photoelectric switch so as to obtain an accurate rotation angle of the gear plate mechanism according to times of change by using a conventional method and position preliminarily precisely. The advantages are as follows: the volume is small, positioning is accurate, and the test method is simple.
Description
technical field [0001] The invention relates to the field of measuring the rotation angle of a toothed disc mechanical device, in particular to a method for realizing angle measurement of a toothed disc mechanical feedback loop. Background technique [0002] Rotation angle measurement is necessary for toothed disc mechanical devices. Angle measurement methods include optical dividing head method, self-collimation method, polyhedral prism method, etc. These methods are high-precision dynamic angle measurement methods. However, some equipment does not require high-precision angle measurement, especially for small toothed disc mechanical devices. Due to the small internal space and compact structure, it cannot accommodate larger and high-precision angle measurement devices. In order to achieve real-time angle positioning, A simple and reliable angle measurement method needs to be studied for these small toothed disc mechanisms.
