Description

Technical Field

[0001] This utility model relates to the field of aviation component mold technology, and in particular to a clamping fixture for PIID coating inspection of aviation component molds. Background Technology

[0002] Clamping fixtures play a crucial role in PIID coating inspection of aerospace component molds. The specific functions are as follows: 1) Ensuring Inspection Accuracy: During PVD coating inspection, clamping fixtures stably fix the aerospace component mold under test, preventing movement or deformation during inspection. This ensures that the testing instrument can accurately measure various performance parameters of the coating, such as thickness, hardness, and adhesion, thereby improving the accuracy and reliability of the inspection. 2) Improving Inspection Efficiency: The design of clamping fixtures makes the inspection process more efficient. By quickly and accurately clamping the parts under test, the time and error of manual operation are reduced, improving inspection efficiency. At the same time, the clamping fixtures can be flexibly adjusted according to inspection needs to adapt to aerospace component molds of different shapes and sizes, further improving the versatility and flexibility of the inspection. 3) Enhancing Inspection Safety: The use of clamping fixtures also enhances the safety of the inspection process. During inspection, operators can safely handle the parts under test using the clamping fixtures, avoiding direct contact with the high-temperature or high-pressure coating surface, thus reducing operational risks.

[0003] Traditional clamping fixtures for inspecting PIID coatings on aerospace component molds have shortcomings. They cannot reliably clamp the molds, nor can they rotate them after clamping to meet the inspection requirements for PIID coatings in insufficient areas. Therefore, optimization and improvement are necessary. Utility Model Content
