The main corner measuring devices adopted by the domestic front axle assembly line are as follows.
The first is an "automobile steering angle measuring instrument" published under the publication number CN101315275A as published on 3.12.2008, wherein the simple angle measuring ruler mainly uses human eyes to read the data on the measuring ruler through infrared spots on the angle measuring ruler to measure the steering angle. The measuring device has higher requirements on the technical level of operators, and has low measuring precision although the operation is convenient; and because the measured data can not be collected, the measured data of the angle can not be stored, whether the product is qualified or not is judged manually, and the quality monitoring in the assembling process can not be carried out.
The second one is a wheel rotation angle measuring device, a wheel rotation angle control system, a wheel rotation angle measuring method and a wheel rotation angle control method disclosed in CN106143599A, 11/23/2016, in which a triangle is formed by a measuring device, a knuckle and a front axle by using a cable, a cable sensor and other mechanisms, and a steering angle of the knuckle is indirectly calculated by measuring a side length of the triangle.

The measuring device can realize measurement on the premise that the knuckle kingpin is provided with the spigot, and the corner measuring device can be embedded into the spigot of the kingpin, so that the axis of the measuring device is ensured not to rotate. Therefore, the measuring device is poor in applicability, workers on two sides are required to operate cooperatively during operation, operation is not convenient, and detection precision is greatly influenced by human factors.
The foreign rotation angle measuring device mainly uses a horizontal camera and a vertical camera to measure the steering angle. The horizontal camera detects the straight ahead of the axle and determines the initial angle of the knuckle, and the vertical camera detects the angle through which the knuckle turns. The corner measuring device needs to accurately fix the front axle, and the front axle needs to be clamped and fixed during detection, so that the requirement of movably assembling the front axle on the existing plate chain line and roller path line cannot be met, the corner measuring device is not suitable for the transformation of a front axle assembly line, and the applicability is poor.
In conclusion, the existing corner measuring device generally has the defects of low automation degree, low measuring precision, inconvenient operation, poor applicability and the like. Therefore, it is urgently needed to develop a corner measuring device with high automation degree, high measuring precision, convenient operation and strong applicability to improve the automation level of axle assembly and improve the labor efficiency and the production quality.
