[0029] The linkage bevel gear 9 is arranged in the positioning tooth groove 8, and the two are meshed and connected. When the position needs to be adjusted, the linkage bevel gear 9 rotates to drive the relative movement of the entire position sensor 1.

[0030] The inner surface of one end of the embedded ring groove 4 is fixedly connected between the positioning tooth groove 8, the positioning tooth groove 8 is meshingly connected between the linkage bevel gear 9, and the upper end of the linkage bevel gear 9 is fixedly connected between the rotating rod 10.

[0031] The embedded ring groove 4 is located at the core part of the position sensor 1 and serves as a basic support point for other components, thereby ensuring the stability of the overall mechanism.

[0032] The upper end of the rotating rod 10 is movably connected with the micro motor 11, the outer end of the micro motor 11 is wrapped in the central inner surface of the linkage ring 3, and the positioning groove 6 is embeddedly installed in the lower end inner surface of the linkage ring 3.

[0033] The positioning groove 6 is wrapped around the outer end of the positioning rod 5, the positioning rod 5 is fixed to the upper end outer surface of the ring-shaped frame 2, and the positioning screw 7 fixes the positioning rod 5 and the positioning groove 6.

[0034] The linkage ring 3 is connected with the embedded ring groove 4, and the positioning groove 6 is used in cooperation with the positioning rod 5 to realize the functions of position adjustment and fixation.

[0035] The positioning rod 5 penetrates through the linkage ring 3, the lower end of the positioning rod 5 is fixed by the ring-shaped frame 2, and the positioning screw 7 ensures that the positioning rod 5 is tightly attached to the positioning groove 6, thereby providing stable support and precise position locking capability.

[0036] The outer end of the micro motor 11 is connected with an induction module, and the induction module is used for monitoring the position information of the displacement sensor.

[0037] The induction module is the core part of the control system, the induction module monitors the state of the position sensor 1 in real time, sends instructions to the micro motor 11, and ensures that the sensor is always in the best detection position.

[0038] The rotating rod 10 connects the linkage bevel gear 9 and the micro motor 11, the power output of the micro motor 11 is directly converted into the rotation of the rotating rod 10, which further affects the action of the linkage bevel gear 9, thereby realizing automatic position adjustment.

[0039] The ring-shaped frame 2 and the linkage ring 3 are both semicircular in shape, the ring-shaped frame 2 is fixed in the motor body by screws, and the input and output ends of the position sensor 1 are respectively connected with the motor body.

[0040] The installation stage: the ring-shaped frame 2 is fixed to the inner side of the motor body, and the position sensor 1 is electrically connected with the motor body by hot plug. At this time, the linkage ring 3 and the position sensor 1 are relatively stationary, and are ready for use.

[0041] The starting stage: after power supply, the micro motor 11 is activated by the induction module, and is adjusted to the initial detection position according to the preset program, thereby laying a foundation for subsequent operation.

[0042] Detection process: as the motor starts, the induction module continuously monitors the motor shaft dynamics, and once the position deviation is found (such as due to temperature change or vibration), the micro motor 11 is immediately commanded to drive the linkage to fine-tune the position sensor 1, ensuring that the most accurate position data is always captured.

[0043] High efficiency feedback: even if the environmental factors are complex and changeable, the position sensor 1 can still quickly respond and adapt to the ideal detection state to achieve accurate measurement, significantly improving the stability and accuracy of the motor control system.

[0044] When the present application is used: first, the linkage ring 3 and the position sensor 1 are fixed by the annular frame 2 and the positioning screw 7, and the annular frame 2 is fixed to the inner end of the motor body by a screw, and the two ends of the position sensor 1 are connected between the motor body and the hot plug by a wire harness, the motor body is fully installed, after installation, the motor body is powered, and after the motor body is powered, the position sensor 1 inside is controlled by the induction module to drive the micro motor 11 to operate in advance, to ensure the position stability of the position sensor 1, so as to detect the position of the motor shaft in the motor body, avoid the position of the position sensor 1 unstable, leading to inaccurate detection of the position of the motor shaft in the motor body, through the position sensor 1 adjusts the change of position information before each operation of the motor, which can well maintain high-precision measurement under the condition of small deviation caused by temperature change, mechanical vibration or long-time operation of the motor shaft after the motor runs;

[0045] When the position sensor 1 automatically adjusts the position, the micro motor 11 drives the rotation of the rotating rod 10, drives the rotation of the linkage bevel gear 9, ensures the mutual engagement of the linkage bevel gear 9 and the positioning tooth groove 8, and drives the rotation of the position sensor 1 under the linkage of the embedded ring groove 4, the linkage ring 3 and the annular frame 2, so as to adjust the position.
