Description
Technical Field
The invention relates to the field of tire quality detection, in particular to detection equipment for the jumping amount and the deflection amount of a tire.
Background
The requirements on the quality and performance of tires are higher and higher due to the rapid development of the traffic automobile industry at home and abroad. The degree of run out (out of roundness) of a tire is an important technical indicator for tire uniformity detection to indicate geometric non-uniformity of the tire. In the tire detection, the height of the index reflects geometric defects such as bulges and depressions of the tread and the sidewall of the tire, if the defects are too large, the running state of the wheel is affected, so that vibration and jolt are formed when the vehicle runs, passengers feel poor comfort, and the running stability of the automobile is affected; increasing the chance of failure and affecting the service life of the tire. Therefore, the quality detection of tires by tire enterprises, and the degree of run-out (out-of-roundness) are one of the important technical indexes. The degree of run-out (out-of-roundness) of a tire has two main parameters: one is radial runout, which refers to the error in tire diameter or circumference. This error causes the vehicle body to run out up and down, which is called radial run out. One is the lateral runout, which is the geometrical non-uniformity of the sides of the tire, the geometrical defects such as bulging and sagging on the lateral surface of the tire. During operation, this geometric defect causes the vehicle body to sway from side to side, known as lateral runout.
Based on the measurement of the tire runout of the non-contact laser displacement sensor, the corresponding lateral runout and radial runout are measured through the high-precision surface measurement of the tire, and the process problems in the tire manufacturing process can be clearly identified and diagnosed, so that the quality of products is improved. The measurement of the degree of run-out is also an effective means of ensuring the continuous improvement of the product quality. However, no detection device capable of simultaneously detecting the tire runout and the runout is provided in the existing tire quality detection, so that the tire runout and the runout are often required to be measured for multiple times, the tire runout and the runout can be judged, and the detection precision of the existing tire quality detection device is low.
