The invention discloses a carbon
fiber cloth winding forming device for small-
diameter shaft products and a method for
machining the same. The carbon
fiber cloth winding forming device comprises a mandrel, clamp rings, a front barrier and a rear barrier. The front barrier and the rear barrier sleeve the mandrel; a carbon
fiber cloth winding section of the mandrel is formed between the front barrier and the rear barrier; a
bushing in the shape of a cone cylinder and a
throat liner sleeve the carbon fiber cloth winding section; the
throat liner comprises a
throat, a first conical section and a second conical section, the throat sleeves the mandrel, the first conical section sleeves a transition
conical surface, and the second conical section sleeves an outer
conical surface of the
bushing; an end surface of the
bushing is in contact with the side walls of the rear barrier; corresponding stress surfaces can be respectively formed between the first conical section and the transition
conical surface, between the second conical section and the outer conical surface of the bushing and between the end surface of the bushing and the side walls of the rear barrier when carbon fiber cloth is formed by means of winding. The carbon fiber cloth winding forming device and the method have the
advantage that the problem of bending deformation or breakage of mandrels of winding mechanisms due to clamping force and tensioning force of carbon fiber cloth when components of small-
diameter long hole products are wound can be solved by the aid of the carbon fiber cloth winding forming device and the method.
