Background
The automobile engine can convert chemical energy of fuel or other forms of energy into mechanical energy to provide power for the automobile, is the heart of the automobile and belongs to a technology-intensive product. With the development of economy in China, the automobile industry is rapidly developed while the demand for automobiles is increased day by day, and the performance requirements of people on automobile engines are higher and higher.
In an automobile engine, an air inlet and exhaust valve is a component which is composed of a disk part and a rod part which is coaxially arranged with the disk part into a whole, belongs to one of key parts of the automobile engine, is a door of an engine combustion chamber, is a key basic part for sealing an air inlet and exhaust port in the working process of the engine, and is used for blocking an air flow channel and controlling the gas exchange of the engine. During each operation of the engine, the intake and exhaust valves are opened and closed once each, and the valves are subjected to the pressure of the valve spring and the pressure of seating during the opening and closing of the valves. The intake and exhaust valves function to seal the combustion chamber, particularly during the compression and power strokes. Therefore, the quality of the valve quality has a significant impact on engine performance and life.
The machining precision and structure of the valve play a role in lifting the motion of an engine valve mechanism, and meanwhile, the total length size of the valve is a key parameter of the valve, which is a design reference and a process and detection reference, and is almost closely related to the precision of all parts of the valve. The traditional valve total length detection mode needs to be completed by a large number of workers by adopting a vernier caliper, so that a small plane behind a front cutting edge of the vernier caliper is contacted with a large end face of a valve, and the measurement result is the distance from one plane to one straight line. Because the big terminal surface of valve is unprocessed or the machining precision is low, and surface shape error is big for there is the error in measuring result and valve actual length. Therefore, the existing detection technology has high detection cost and low efficiency, is easily influenced by factors of operators, is easy to cause instability of detection due to human visual fatigue, and increases the error rate of products. It is difficult to meet the continuously improved product quality requirements.
In addition, the valve stem is the part which works in the valve guide, and the straightness of the stem directly influences the normal work of the valve. In the factory production process, the straightness of the valve rod part is ensured by straightening. In the existing valve production enterprises, some valve production enterprises mainly rely on a universal tool microscope to detect the straightness of the valve rod. Because the inspection cost is high and the required time is long, the straightness and times of inspecting the valve rod part and the batch are very limited, and the straightening process is directly considered to be guaranteed. While businesses without a universal tool microscope typically do not examine this item.
