Embodiment Construction

[0015] The present invention will be further described in detail below with reference to the drawings and embodiments.

[0016] Such as figure 1 As shown, the present invention consists of a linear displacement sensor with a movable ruler head 1 (linear displacement sensor A10, linear displacement sensor B11, linear displacement sensor C12), a moving mechanism, and a shaft. Among them, there are three linear displacement sensors, each of which is linear The displacement sensors are respectively installed on the moving mechanism through the moving ruler head 1, specifically: one end of the linear displacement sensor A10 is installed on the A axis 9, and the other end is installed on the D axis 16 together with one end of the linear displacement sensor B11. The linear displacement sensor One end of C12 is installed on the B axis 13, and the other end is installed on the C axis 14 together with the other end of the linear displacement sensor B11. The three linear displacement sensor...

Description

Technical field [0001] The invention relates to measurement technology engineering and mechanical design engineering, in particular to the structure of a rotation angle measurement mechanism. Background technique [0002] At present, in the parallel quadrilateral measuring angle mechanism constructed by using linear displacement sensors as measuring components, various structural design forms can be adopted. However, according to the actual situation, when the measurement accuracy is high, the requirements for mechanical structure design are relatively high. High, how to ensure the design requirements and introduce small processing errors is the key to the design. Regarding the measurement principle of this mechanism, how to ensure that the linear displacement sensor's movement track is parallel or coincident with the connecting line of the rotation axis at both ends and the calibration of the initial position parameter is the difficult point to improve the measurement accuracy. ...
