Description

Technical Field

[0001] The utility model relates to the technical field of tire wire ring measurement, in particular to a device for measuring the inner diameter of a wire ring. Background Art

[0002] When producing tires, the inner circumference of the wire ring needs to be determined based on the size of the inner diameter of the tire mold. However, mass-produced wire rings are prone to errors during the production and processing process, which directly affects the quality of the finished tire. Therefore, it is necessary to measure the inner circumference of the wire ring again before using it to confirm whether it is within the allowable error range. At present, measuring the inner circumference of the wire ring requires a special measuring instrument, which is not only expensive, but also requires measurement by stretching and fixing the wire ring from the inside. The pressure applied during the stretching process will cause the wire ring to deform and the inner diameter to increase, affecting the measurement results.

[0003] In order to improve the accuracy of wire ring measurement, a method has emerged on the market that uses a CCD lens to obtain a picture of the wire ring, converts the image pixels of the wire ring into digital signals, and combines with a computer system to calculate the inner diameter of the wire ring. However, when the wire ring is manually placed at a designated light source, it is easy to cause a deviation from the recognition range of the CCD lens, and it often takes multiple adjustments to reach the designated position.

[0004] Therefore, the prior art needs to be further developed. Utility Model Content
