Abstract

The invention relates to a method for machining a head-cone-hat-shaped integral FRP cabin section with an angled end face, comprising the following steps: clamping and fixing the cabin section on a workbench through tooling; the tooling includes: a die and a punch; the die includes: Plane A and plane B opposite to plane A, plane A is provided with a groove; the surface of the groove matches the outer surface of the cabin; the outer surface of the punch matches the inner surface of the cabin; the end surface of the punch is Plane C; align the end face of the punch; press the end face of the punch through the pressure plate; determine the plane A of the die as the processing reference of the cabin section; rough mill the end surface and sealing groove of the cabin section; finely mill the end surface and seal of the cabin section groove. This mechanical processing method changes the processing standard, facilitates clamping and alignment, ensures the butt joint size of the end faces, and improves the qualified rate of finished products.

Description

technical field [0001] The invention relates to the technical field of machining, in particular to a method for machining a head-cone hat-shaped integral glass fiber reinforced plastic cabin section with an angled end face. Background technique [0002] The conventional glass fiber reinforced plastic cabin section is a head-conical hat-shaped structure, and the inner and outer surfaces are power curves. The end surface is composed of two oblique cut surfaces forming a certain angle with each other, and there is a sealing groove perpendicular to the end surface on the end surface. The integral glass fiber reinforced plastic is molded. The pieces are machined into shape. At present, the end faces and annular grooves of conventional FRP cabins are processed by turning. However, since the cabin end face involved in the present invention is composed of two oblique cut surfaces forming a certain angle with each other, the method of turning is not applicable, and it needs to be co...
