Description

Technical Field

[0001] The utility model relates to the technical field of engine valve measurement, and specifically discloses a measuring device for engine valves. Background Technique

[0002] In the engine system, the engine valve needs to operate in a harsh environment for a long time and has a very high operating frequency. Therefore, the external dimensions of the engine valve are required to be very strict, and its production accuracy requirements are also relatively high. The engine valve mainly consists of a valve stem and a valve head, and the outer surface of the valve head is a curved surface. Since the dimensions of the engine valve parts are small, it is suitable for batch and rhythm production. In batch production, in order to ensure the quality and quantity of production, operators need to monitor the quality of the engine valves to ensure that the produced engine valves strictly meet the standards.

[0003] At present, when operators conduct spot checks on engine valves, they generally use a curvature digital display meter to detect the curvature of the curved surface of the valve head. Usually, the operator needs to tightly hold the valve stem of the engine valve with the left hand, hold the digital display meter with the right hand, make the probe of the digital display meter contact the curved surface of the valve head, and at the same time rotate the valve stem with the left hand to complete the all-round curvature measurement and detection of the curved surface of the valve head. In the above measurement operation process, since the operator needs to manually rotate the valve stem for a long time, it is easy to cause a high sense of fatigue for the operator. In the long run, it will directly affect the accuracy of the curvature measurement, seriously reduce the accuracy of the quality monitoring of the engine valve, and thus bring inestimable losses to the enterprise.
