Description

technical field [0001] The invention relates to a cylinder diameter measuring device for mechanical parts, in particular to a cylinder diameter measuring device for the inner hole of a pulley. Background technique [0002] At present, the quality of automobile engines is improving rapidly, whether it is life, noise, energy saving, or stability. Improving the dimensional accuracy and shape accuracy of the engine pulley is also an important part of improving engine quality. The traditional measurement of the length of the pulley adopts conventional measurement methods, and manual measurement is performed by tools such as vernier calipers. [0003] This measurement method has low efficiency. It is controlled by human hands during measurement, which affects the accuracy of measurement. There is also measurement parallax when reading, which brings great errors to the measurement results. These traditional inspection methods are obviously It cannot meet the technical development ...
