Background
The air inlet valve and the air outlet valve of the automobile engine are both mushroom-shaped air valves and are composed of two parts, namely an air valve head and an air valve rod. The top surface of the valve has a flat top, a concave top, a convex top and the like. At present, the most applied valve is a flat-top valve, which has simple structure and small heating area, and can be used for both intake and exhaust valves. Because the valve rod controls the opening and closing of the automobile engine valve, the requirement of the valve rod on the precision is high. After the valve rod is formed through punching, the head part of the valve rod and the valve rod need to be further and respectively subjected to finish machining, so that the precision of the valve rod is improved. At present, the stem part of the valve stem is finely processed by conveying the valve stem to a guide plate between a grinding wheel and a guide wheel of a centerless grinding machine through an arc slideway and grinding the stem part of the valve stem by the rotation of the grinding wheel. One drawback of the conventionally used arc slide-to-feed is that when the valve stem is slid through the arc for transportation, the end of one valve stem collides with the end of the stem portion of another valve stem, causing scratches on the end slope of the valve stem, since the valve stem is slid through the arc next to the valve stem for transportation. Therefore, in order to solve the above problems, it is necessary to provide a new feeding mechanism.
