Technical Field
The utility model relates to the technical field of flatness testing of aluminum alloy die castings, in particular to a digital flatness testing device based on visual sensing.
Background
Planarity refers to the deviation of the macroscopic debossment height of a substrate from the ideal plane. The flatness is an index for limiting the fluctuation of the actual plane to the ideal plane, and is used for controlling the shape error of the measured actual plane. At present, the requirement of die casting products on flatness is higher and higher, particularly thin plate die casting products such as display screen mounting plates and the like generally have higher requirement on flatness, and a plurality of even more than ten different detection points are arranged on the surface of the thin plate die casting products, and flatness measurement is carried out on the detection points. The traditional flatness testing device has a complex flatness calculation method, and has the disadvantages of low measurement speed, large calculation amount and complex data post-processing work for batch detection work.
