Embodiment 1

[0023] The outer diameter of the flexible rod 2 is d = 4764.2 μm, the sensor bushing 3D = 4766.5 μm, D-d = 2.3 μm. Use step 2 to rotate the flexible rod 2 one circle, measure the variation Δt1 of the output values ​​of the four channels of the sensor, Δt1=A=B=C=D=26 μm; continue to adjust the angle of the sensor bushing 3; remove the sensor 5, Rotate the sensor bushing 3 clockwise by 90°, and then reinstall the sensor 5; rotate the flexible rod 2 once, measure the variation Δt2 of the output values ​​of the four channels of the sensor, Δt2=A=B=C=D=18μm, and continue to adjust The angle of the sensor bushing 3; remove the sensor 5, continue to rotate the sensor bushing 3 90° clockwise, and then reinstall the sensor 5; rotate the flexible rod 2 one circle, and measure the variation of the output value of the four channels of the sensor Δt3 , Δt3=A=B=C=D=14 μm≤15 μm. Then the zero position debugging of the sensor 5 was successfully completed.

Embodiment 2

[0025] The outer diameter of the flexible rod 2 is d = 4764.2 μm, the sensor bushing 3D = 4765.8 μm, D-d = 1.6 μm. Use step 2 to rotate the flexible rod 2 one circle, measure the variation Δt1 of the output values ​​of the four channels of the sensor, Δt1=A=B=C=D=17 μm; continue to adjust the angle of the sensor bushing 3; remove the sensor 5, Rotate the sensor bushing 3 clockwise by 90°, and then reinstall the sensor 5; rotate the flexible rod 2 once, and measure the variation Δt2 of the output values ​​of the four channels of the sensor, Δt2=A=B=C=D=11μm≤15μm, The zero position debugging of the sensor 5 is completed.

Embodiment 3

[0027] The outer diameter of the flexible rod 2 is d = 4764.5 μm, the sensor bushing 3D = 4765.7 μm, D-d = 1.2. Use step 2 to rotate the flexible rod 2 one circle, measure the variation Δt1 of the output values ​​of the four channels of the sensor, Δt1=A=B=C=D=11μm≤15μm, and the sensor 5 has been adjusted for zero position.

Abstract

The invention belongs to a sensor debugging technique and relates to the improvement on a zero-debugging method of a sensor for a main control valve of a steering engine actuator. The zero-debugging method is used for carrying out mechanical zero debugging to a sensor [5] and comprises the following steps of: adjusting a gap between a flexible rod [2] and a sensor bush [3]; measuring the change amounts of four-channel output values of the sensor [5]; and adjusting the angle of the sensor bush [3]. The zero-debugging method can solve the problem of the ultra-poor consistency of the four-channel output values of the sensor after the main control valve is installed on the steering engine actuator and improve the assembling and debugging efficiency of the steering engine actuator.

Description

technical field [0001] The invention belongs to the sensor debugging technology, and relates to the improvement of the zero adjustment method for the main control valve sensor of the steering gear actuator. Background technique [0002] The main control valve of a certain type of steering gear actuator is the heart of the steering gear, and whether its performance is stable is one of the factors that affect the performance of the steering gear. For the connection relationship between the main control valve and the installed four-degree sensor, see figure 1 . A flexible rod 2 is installed in the central hole of the spool 1. The sensor bush 3 is sleeved on the flexible rod 2 and is located on the right side of the spool 1. The right end of the flexible rod 2 is connected with the sensor 5 through the bearing 4 as a whole. At present, the zero adjustment method of the sensor is: adopt the direct mechanical zero position debugging method, that is, realize the zero adjustment o...
