At present, the sensor used in the angle measuring device of microcomputer is widely used in industrial automatic control system, automatic instrument and mechanical equipment that needs line position control, and is used as electromechanical conversion element for linear displacement measurement. Specifically, it is suitable for missile, flight navigation instrument and wing balance control system. The existing angle sensor is determined according to the elastic variable produced by the rotation angle to the machine, so it is suitable for measuring small angle. If it is used for the measurement of two-way large angle, it will produce large error. Secondly, the existing angle sensor has complex structure, high manufacturing cost and inconvenient installation.
summary of the invention
To solve the above technical problems existing in the existing sensors, a self reset angle conversion linear pulling rope is provided Displacement sensor
Compared with the existing sensor, the invention has the following advantages:
1. In the effective stroke of a 350 degree diameter 35mm angular displacement product, by changing the runner x π, the wheel can arbitrarily design the required control length, and can arbitrarily design the effective angle and starting force distance according to the needs.
2. Simple design and convenient installation.

Specific implementation mode
Under the condition that the installation space of industrial control automation machinery is strictly limited, the angle rotation movement is adopted. According to the definition of PI, the diameter of Runner 2 is designed, and the steel cable 4 and limit sheath 3 are used. One end of the steel cable 4 is fixed at the required position of the runner 2, and the other end can be connected to the required length. By using the principle of automatic reset, the rotary motion is converted into linear motion, and the angle suitable for linear motion is not limited by the position when the angle can be changed.
As shown in Fig. 1, the self reset angle changes the straight-line pulling rope Displacement sensor It includes shell L, Runner 2, cable limit sleeve 3, Steel wire cable 4, fixed cover plate 5, cover 6, self reset precision angle sensor 7, lead out cable 8, shaft 9, self reset precision angle sensor 7, fixed cover plate 5, Runner 2 are successively sheathed on shaft 9, self reset precision angle sensor 7 and fixed cover plate 5 are connected by screws, housing 1 is covered on one side of fixed cover plate 5, Runner 2 and shaft 9, and housing cover is on the side of self reset precision angle sensor 7 On one side, the cover 1 and the cover 6 are respectively connected by screws and the fixed cover plate 5. The cable limit sleeve 3 is set on the steel wire cable 4 and fixed on the shell 1. One end of the lead-out cable 8 is fixed on the self reset precision angle sensor 7, and the other end is inserted outside the housing 6 through the preset hole on the cover 6.
As shown in Fig. 2, four screw holes are arranged on the right side of the shell 1. The structure of the shell 1 can be firmly connected with the internal precision angular displacement sensor and other parts.
As shown in Fig. 3, the position of cable outlet hole can be arbitrarily selected according to the demand of cover 6, which is convenient for installation and use.
The shell 1, Runner 2, fixed cover plate 5 and cover 6 are made of alloy aluminum, and the surface is oxidized. Through the outgoing cable 8, the connection and installation mode can be selected as required.
