Background

The production process of the automobile steering ball rod mainly comprises cold heading, thread rolling, surface treatment, ball head processing and the like, and the automobile steering ball rod is an important part in an automobile steering system. Therefore, the accurate detection and control of the length dimension of the automobile steering ball rod is the quality assurance of an automobile. Currently, there are mainly 3 sizes for the finished length of an automobile steering cue: the groove shape is away from the center of the sphere, the hexagonal side is away from the center of the sphere and the left end starting surface of the thread is away from the center of the sphere. The three sizes are all based on the sphere center, so that the three sizes cannot be directly measured by using a simple caliper and the like, and professional measuring personnel need to find the sphere center position firstly and then measure the size by using a projector, a three-coordinate measuring device and other measuring equipment.

Although the existing detection scheme can judge whether the product is qualified according to the measured accurate size value, the method needs large equipment investment (a projector, three coordinates and the like) and personnel investment (professional measuring personnel). Therefore, the detection efficiency of the method is low, and what is needed for general enterprises is a measuring tool and a method which can quickly detect whether parts are qualified or not and are simple and convenient to operate. Especially, in the field part production stage, if a measuring tool and a method capable of quickly measuring exist, the continuous production of parts and the control of the quality of products can be ensured.

Therefore, in order to solve the technical problem, the utility model provides a quick measuring tool for checking the length and the size of a finished automobile steering ball rod.
