[0002] Suspension springs are key components in the vehicle suspension system. Their main function is to establish an elastic connection between the axle and the frame or body, bear and transmit vertical loads, and mitigate and suppress the impact caused by uneven roads. In addition, suspension springs can also absorb vibrations through their own compression deformation when the vehicle is impacted by the road, reduce bumps and vibrations, and improve ride comfort and vehicle driving stability.

[0003] With the rapid development of the automotive industry, the requirements for the consistency of suspension springs are becoming more and more stringent. It is necessary to detect the inner diameter of the suspension spring end ring to ensure the consistency of the spring size. Suspension springs are complex in shape and difficult to detect. At present, the detection personnel mainly use vernier calipers to perform multiple measurements; however, the end ring of the suspension spring is not a regular circle. Using this method for detection is not only inefficient, but also difficult to ensure the consistency of the inner diameter size of the spring end ring. Utility Model Content
