Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of external diameter detection equipment, and specifically relates to a novel cold plate water nozzle external diameter detection gauge. BACKGROUND

[0002] With the vigorous development of new energy automobile industry, Kirin battery as the representative of new generation high performance battery technology is gradually becoming the core power source of many electric vehicle projects. Kirin battery promotes the substantial improvement of electric vehicle endurance mileage with its excellent energy density, safety performance and cycle life, and further promotes the continuous innovation of battery pack and its component design. Among them, the water nozzle as a key component in the battery pack cooling system, the accuracy of its quality and size is directly related to the cooling efficiency and the overall reliability of the system.

[0003] However, with the wide application of Kirin battery, the types and quantities of water nozzles have also increased, which puts higher requirements on the production quality control of water nozzle components. Especially the detection of water nozzle external diameter, as a basic link to ensure its sealing and installation adaptability, its importance is self-evident. At present, the external diameter detection schemes mainly used in the industry include vernier caliper detection, three coordinate detection and integrated external diameter go-no-go gauge detection.

[0004] Although the vernier caliper detection is simple to operate, the precision is limited by human operation error, which is difficult to meet the high precision detection demand. Although the three coordinate detection has high precision, the detection period is long and the cost is high, which is not suitable for rapid detection demand on large-scale production line. Although the integrated external diameter go-no-go gauge improves the detection efficiency to a certain extent, it is designed for specific size water nozzle, and has poor universality. Once the water nozzle specification changes, it needs to be re-designed, which undoubtedly increases the production cost and time cost.

[0005] More importantly, the existing detection methods have obvious limitations when facing non-standard circular water nozzles. Due to the limitation of design principle, these detection tools often cannot comprehensively and accurately evaluate the compliance of the entire water nozzle external diameter, especially when the water nozzle shape appears slight deformation or irregularity, the existing detection means is easy to fail, leading to defective products flowing into subsequent processes, which seriously affects product quality and safety.

[0006] Therefore, it is urgent to develop a water nozzle external diameter detection device with high efficiency, high precision and strong universality to meet the detection needs of water nozzle components in Kirin battery and more types of battery pack cooling systems in the future, INVENTION CONTENTS
