The processing of pipe is the basis for promoting composite products to more fields. Only with a certain size precision, the application field of composite pipe can be better expanded. The pipe product formed by using continuous winding forming process and pultrusion process is hollow structure, and there is no support inside. Because of the diameter, wall thickness and material factors of large composite pipe, the cross section will have slight deformation, mainly as upper and lower flattening, out-of-round, axial self-weight sagging, etc., which increases the difficulty of subsequent processing, and the end face indexing circle drilling and barrel section drilling angle become the processing difficulties.

[0003] At present, the drilling of composite tubular product is often positioned by special tooling. In order to enhance the rigidity of tubular product, annular lining measurement processing is used to improve the clamping accuracy, but the structure is complex, the manufacturing cost is high, and the universality is poor. In the machining process of the original technology, the tubular product is fixed by inner support, and the end face is drilled. Because the rigidity of the tubular product itself is not enough, it is easy to deform in the clamping process, so that the composite tubular product and the special tooling positioning are not located on the same concentric axis, so that the clamping positioning accuracy is not high, and the technical requirements cannot be met.
