Description

technical field

[0001] The invention relates to the field of automatic measurement and control, in particular to an on-line deformation measurement system of an automobile aluminum alloy wheel hub blank, which realizes on-line measurement of the deformation of the rim surface of the wheel hub blank and the axial deformation of the center of the wheel hub. Background technique

[0002] With the development of modern society, the automobile industry has gradually become one of the pillar industries in China. As one of the important components of automobiles, aluminum alloy wheels are widely used because of their advantages such as light weight, small deformation, environmental protection and energy saving.

[0003] In the production process of aluminum alloy wheels, due to the influence of factors such as the size of the abrasive tool, casting method, thermal deformation of the blank, heat treatment, etc., the actual shape of the wheel hub blank will have a certain deviation f...
