The salt spray corrosion testing device provided by this invention combines salt spray corrosion with the wind speed of the salt spray, incorporating the influence of wind speed into the salt spray test of the test samples. This makes the test more closely resemble real-world environmental scenarios, allowing the salt spray test to approximate the tolerance level of the test samples under real environmental conditions, resulting in more accurate test results and enhancing the practical guiding significance of the test results.

[0003] However, in the above-mentioned solutions and existing technologies, when conducting salt spray corrosion tests on brake components, the brake components are usually placed directly on the tray inside the salt spray corrosion test device. During the process, the corrosion products of the brake components are easily stuck to the tray, and the salt spray condenses into liquid and remains on the tray. The trays of existing devices are usually integrated into the device or fixed by bolts, making it inconvenient to disassemble and clean the trays. Improvements and optimizations are needed.

[0004] Therefore, this utility model proposes a salt spray corrosion testing device for brake production to solve the above problems. Utility Model Content

[0023] The tray 5 is equipped with a pin column 7, which is suitable for placing brake plate and column accessories, thereby raising the brake accessories and increasing the contact area between the brake accessories and the salt spray environment. The salt liquid condensed on the tray 5 and the brake accessories falls onto the slope surface 6.

[0024] The tray 5 has symmetrically arranged filter holes 8 on both sides of the side wall. The filter holes 8 are located on the bottom side of the slope surface 6. T-shaped plates 9 are symmetrically connected to the outer walls of both sides of the tray 5. Connecting plates 10 are symmetrically connected to the inner wall of the main body 1 of the salt spray corrosion test device.

The clamping plate 16 and the weight block 17 are rotated to expose the slot 12. The insert plate 13 is inserted into the slot 12 and engages with the T-shaped plate 9 to ensure the stability of the tray 5. Then the weight block 17 is released. Under its own weight, the weight block 17 rotates to the underside of the arc block 15 until the clamping plate 16 engages with the slot 14. At this time, the first magnetic block 18 and the second magnetic block 19 attract each other to help fix the weight block 17 in a fixed position and complete the installation of the tray 5. The brake accessories are placed on the pin column 7 on the tray 5 to support the brake accessories.
