Description
Summary:Camshaft is the key component of automobile engine valve timing mechanism, whose machining precision will affect overall performance of automobile engine. This paper presents a kind of camshaft journals multi-parameters measuring instrument based on the actual requirement of camshaft production. The camshaft measuring instrument was auto measuring instrument composed of pneumatic control system, precision measurement system and computer-aided measurement system, which was developed for measuring journal diameter, roundness, conicity, journal radial runout relative to center holes connection, and number 2, 3, 4 journal radial runout relative to number 1 and 5 journal center connection, etc. The measurement repetition and stability were perfect, it was fit for high precision and fast measurement at production site.
