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.

Embodiment
Below the present invention is described in further details.Referring to Fig. 1, zero-debugging method of sensor for main control valve of steering engine actuator comprises sensor 5 is carried out the debugging of mechanical type zero-bit, makes the variation of its four passage output valves be not more than 15 μ m, it is characterized in that the step of zeroing is as follows:
1, adjusts the gap of rods 2 and sensor bush 3, pull down sensor bush 3, measure the outside diameter d of rods 2 and the inside diameter D of sensor bush 3, select sensor bush 3, make D-d=1～3 μ m, reinstall sensor bush 3 and sensor 5 then;
2, the variation of 5 four passage output valves of survey sensor rotates a circle rods 2, the variation Δ t1 of four passage output valves of survey sensor, if Δ t1≤15 μ m, then the sensor zeroing finishes; If Δ t1＞15 μ m then continue next step debugging;
3, adjust the angle of sensor bush 3, sensor 5 is pulled down, with sensor bush 3 clockwise or be rotated counterclockwise 90 ° ± 20 °, reinstall sensor 5 then;
4, repeating step 2, remeasure the variation of 5 four passage output valves of sensor; Rods 2 is rotated a circle once more, the variation Δ t2 of four passage output valves of survey sensor, if Δ t2≤15 μ m, then the sensor zeroing finishes; If Δ t2＞15 μ m then continue next step debugging;
5, repeating step 3, readjust the angle of sensor bush 3; Once more sensor 5 is pulled down, sensor bush 3 according to the sense of rotation of step 3 half-twist ± 20 ° once more, is reinstalled sensor 5 then, the sensor zeroing finishes.
Principle of work of the present invention is: the effect of main control valve sensor 5 mainly is the displacement of measuring rods 2, mainly the contradiction of Xie Jueing be control rods 2 rotate influence at random to sensor 5 output, utilize sensor bush 3 and spool 1 separately the depth of parallelism of end face carry out angle compensation, after it was cooperated, whole parallelism error reached minimum value.
The effect of step 1 is: make sensor bush 3 and main control valve rods 2 tolerance clearances less, avoid sensor bush 3 moving when main control valve is worked.
The effect of step 2 is: the work of main control valve mainly is the displacement of rods 2, rods 2 may be in 360 ° of rotation status at random under in working order, the sensor four-way output valve of bringing changes, adding rods 2 in debugging rotates a circle, the variation Δ t of four passage output valves of survey sensor≤15 μ m debug, and just overproof phenomenon can not occur.
