The Design Scheme for Detecting the Thread Rotation Angle of the Cylinder Head Spark Plug

In today's environment where cost reduction, energy saving and environmental protection are strongly advocated, it is the top priority to maximize the effective power of the engine. Among them, the rotation position of the ignition angle of the engine spark plug is also an important point for the improvement of the effective power of the engine, and the rotation position of the spark plug is determined by its carrier-the thread starting point of the cylinder head spark plug thread hole. However, there are many factors that affect the starting point position: the starting point of the thread cutter during machining, the positioning of the cutter during tool change, the positioning during cylinder head clamping, different equipment in the same process and so on. The consistency of these factors must be determined by the angle position inspection equipment of the starting point of the thread of the spark plug hole. At present, the Advanced, sophisticated, high precision inspection equipment is the control means of the Western engine manufacturing power to this problem. This equipment is not only expensive, but the measurement process takes a long time and the testing process is complicated, resulting in very high testing costs.
