Description
Technical Field
The invention relates to the field of high-precision angle measurement of an inner cone of a feedback rod of an electro-hydraulic servo valve, in particular to a high-precision angle measurement method and an auxiliary measurement device of the inner cone of the feedback rod.
Background
According to the simulation result of the feedback rod, the corresponding relation between the pressure difference of the two receiving holes and the opening angle of the V-shaped groove of the feedback rod is not proportional, and meanwhile, the size of the opening angle of the V-shaped groove has large influence on the pressure difference of the two receiving holes. When the opening angle of the V-shaped groove of the feedback rod is in SLSE, the pressure difference of the two receiving holes is the largest, so that the valve core can obtain larger driving force, the oil driving force overcomes the friction force between the slide valve components and the hydraulic force to push the valve core to move, the movement is continued until the feedback moment generated by the bending of the feedback rod is balanced with the pressure difference (the pressure difference between the two receiving holes) at the two ends of the valve core, the larger oil driving force is very favorable for the sensitivity of the electro-hydraulic servo valve, the high-precision small-micro-cavity angle detection is one of bottlenecks which plague the detection cost and the detection accuracy of enterprises, and the conventional detection method is difficult to realize.
The tolerance requirements for the taper angle in the feedback rod, as shown in the feedback rod specification of FIG. 1, are such that the pressure differential across both receiving orifices tends to decrease as the opening angle varies around the SLSE. Therefore, the SLSE +/-10' is required in the drawing, namely the tested inner cone angle is between XX and XX degrees, and the inner cone angle is qualified. If profile measurement is used, the measurement track cannot be consistent with the reference axis, if a three-coordinate measuring machine is adopted, the interior of the small micro cavity cannot be collected, the measurement means at the present stage is limited, and the measurement accuracy and the detection efficiency are not enough to meet the production requirements.
