Description

Technical Field

[0001] The utility model relates to the technical field of autoclaves, in particular to an online detection device for thermal deformation of an autoclave mould. Background Art

[0002] The autoclave process is the mainstream process for high-precision curing and molding of large composite materials. The curing and molding mold is an important part of the autoclave molding process. Its surface dimensional accuracy, surface temperature uniformity and thermal deformation are all key factors affecting the dimensional accuracy of composite materials constructed by the autoclave process. At present, autoclave process molds are mostly made of steel with low thermal expansion coefficient. As the size of composite components increases, the size of the mold also increases accordingly. The curing temperature of raw materials for composite construction is often higher than 180°C. The problem of mold thermal deformation has become a prominent problem that plagues the development of composite autoclave molding technology. Therefore, it is necessary to detect the thermal deformation of autoclave molds.

[0003] After searching: Patent number CN104359416A is an online detection device for thermal deformation of autoclave process mold, including an optical fiber outlet, an optical fiber, and a modem; the optical fiber outlet is arranged on the wall of the autoclave, one end of the optical fiber is connected to the mold to be tested placed in the inner cavity of the autoclave, and the other end passes through the optical fiber outlet and is connected to the modem; the optical fiber includes a test optical fiber and a temperature balance optical fiber.

[0004] However, the above-mentioned online detection device for thermal deformation of autoclave mold still has some shortcomings. Because there are test optical fiber and temperature balance optical fiber, only one hole for optical fiber installation is opened on the sealing plug, so two optical fibers cannot be used. At the same time, it is not conducive to the rapid and effective installation and disassembly of the modem, which is not conducive to the later inspection and maintenance work. Therefore, we propose an online detection device for thermal deformation of autoclave mold to solve the above problems. Utility Model Content
