Description

Technical Field

[0001] This utility model relates to the technical field of salt spray testing machine devices, specifically to the workpiece placement platform of a salt spray testing machine. Background Technology

[0002] A salt spray test chamber is an environmental testing device that uses artificially simulated salt spray environment conditions created by a salt spray test chamber to assess the corrosion resistance of products or metal materials. It is widely used in many fields, such as aerospace, automobile manufacturing, and electronics, and plays an important role in product quality testing and material performance evaluation.

[0003] In traditional salt spray testing chambers, workpieces are typically placed on a support frame constructed from right-angled folded plates and cylindrical rods. However, this traditional method has significant drawbacks. Because the workpiece remains stationary during the test, the distribution of salt spray within the chamber is difficult to guarantee as completely uniform. This results in the workpiece's concealed surfaces often not receiving sufficient and even contact with the salt spray. These concealed areas may exhibit different corrosion characteristics compared to other areas due to insufficient or inadequate salt spray penetration, failing to accurately and comprehensively reflect the workpiece's corrosion resistance in actual operating environments. Consequently, the accuracy and reliability of the salt spray test results are compromised. Utility Model Content
