Technical Field

Background
The feedback rod is an important elastic part in the armature assembly of the servo valve, plays a role of a tie-in of a connecting torque motor, a nozzle baffle pre-amplifier and a slide valve amplifier in the servo valve, and feeds back micro displacement of the valve core to the armature through elastic deformation of the feedback rod. The feedback rod is an elastic part of the slender rod and consists of a cylinder, a cone and a small ball, wherein the cone and the small ball are connected in a necking structure, the diameter of the small ball is generally phi 0.8-phi 1mm, and the minimum diameter of a shaft neck joint is only phi 0.5mm, so that the cone and the small ball need smooth continuous connection transition to ensure that failure risks caused by stress concentration can be avoided in the reciprocating motion of the feedback rod for hundred thousand times.
At present, the joint of the ball cone of the feedback rod is processed in a grinding mode, one end of the feedback rod is propped by a tip during grinding, and the ball end is propped by an organic glass or hard plastic reverse-propping tip. Before grinding the cone segment, the small ball is turned and ground strictly according to the technological requirement, so that the joint of the cone segment is formed in the process of cone segment feed grinding or cut-in grinding, and in order to ensure smooth transition, the grinding wheel must be very accurate when approaching the joint of the cone segment, otherwise, steps are generated. Because the length of the feedback rod and the size of the center have tolerance, after each part is jacked by the center, the positions of the ball cone combination sections of the parts relative to the original point of the machine tool are different, and the ball cutting problem can occur when the interchangeable grinding is directly carried out, so that the design requirement is not met. In the actual production process, an operator firstly needs to adopt visual inspection to perform tool setting on the grinding wheel and the spherical surface, then utilizes a microscope to measure the undercut or overcut quantity at the joint after trial grinding, compensates the axial displacement of the grinding wheel, and because of the difference of each workpiece, each workpiece replacement needs to be measured off-line, so that the labor intensity of workers is high and the efficiency is very low.
