There are not special utensil of examining and have many factors in the in-process of measuring and can influence the error of angle, and the error of angle is too big can lead to the vehicle to turn to in the in-process of traveling to have very big potential safety hazard.
Firstly, a special check tool is not provided, a ruler and a protractor are required to be used manually in a matched mode, positioning reference is difficult to grasp during use, and accuracy of measurement cannot be guaranteed due to the fact that the reference is not right.
Secondly, a special checking fixture is not provided, and the angle error detected by matching the protractor and the ruler is large, so that the angle degree of the front axle assembly can not meet the process requirement easily.
Also, because the corner connector assembly station is not assembled by a fixed operator, the difference in assembly proficiency during assembly can also result in a large error in angle measurement.
Furthermore, when no special checking tool is used for measuring the angle, the operator needs to measure the angle for multiple times, and the labor consumption is very high and the time is long.
