3 Overview
The corner table is a detection instrument that gives an angular displacement based on an angle sensor. It is widely used in comprehensive performance inspection of automobiles.
Inspecting the steering angle of the steering wheel of the car, the main structure consists of left and right frames, floating discs, angle sensors and displays
Part of the composition, as shown in Figure 1. According to the alignment method, it is divided into automatic and manual.
