[0002] In the field of engine manufacturing, rubber tube as an important component of fluid transmission system, its design and manufacturing quality is directly related to the performance and safety of engine. In order to meet the complex and changeable fluid transmission demand, engine rubber tube is often designed to have a special-shaped structure to adapt to different installation space and specific functional requirements. This kind of fabric-reinforced rubber tube with special-shaped structure usually adopts winding core processing method in production and processing process, that is, material is wound layer by layer on pipe core to form the required rubber tube structure.

[0003] However, in the current fabric-reinforced rubber hose production industry, fixed jig is generally used to clamp pipe core for winding core processing. The original intention of fixed jig is to simplify the processing process and improve production efficiency, but when facing fabric-reinforced rubber hose with special-shaped structure, its limitations gradually appear. On the one hand, the clamping method of fixed jig often cannot fully adapt to the complex shape of special-shaped pipe core, resulting in unstable clamping or unable to clamp, which affects the quality and precision of winding core processing. On the other hand, due to the difficulty of manual winding in the process of special-shaped composite rubber tube, the rigid structure of fixed jig limits the flexibility of worker's operation, making manual winding particularly inconvenient, which further leads to low winding efficiency of workers.
