A non-orthogonal structure casing processing method and fixture

Abstract

The invention discloses a non-orthogonal structure cartridge receiver machining method and a clamp. The clamp comprises an angle plate on the bottommost layer, a base is arranged on the angle plate and provided with a positioning ring, and the positioning ring is fixed to the base through a pressing plate and a bolt; a second pressing plate is arranged on the outer side of the positioning ring and used for fixing the edge of the bottom of the outer side of a cartridge receiver to the base; the positioning ring is matched with the bottom end of the cartridge receiver in shape, and the inclining angle of the upper surface of the base coincides with the deflection angle between the center line of the cartridge receiver and the vertical direction; and the base can rotate relative to the angle plate, and a positioning pin is arranged between the base and the angle plate. The non-orthogonal structure cartridge receiver machining method and the clamp have the beneficial effects that according to the technical scheme, the non-orthogonal structure clamp is combined with a milling and turning composite machining method, the problem that installing and positioning during milling and turning composite machining process of a non-orthogonal structure cartridge receiver part are difficult is solved, the process route is shortened, secondary clamping errors are eliminated, the machining quality of the cartridge receiver is guaranteed, the machining efficiency is improved, and the non-orthogonal structure cartridge receiver machining method and the clamp have a good application prospect.

Description

technical field [0001] The invention relates to the technical field of aviation processing, in particular to a casing processing method and a fixture. Background technique [0002] The shape of the non-orthogonal structure casing is as follows: figure 1 As shown, it is an important load-bearing part of the aero-engine. The non-orthogonal structure casing parts have a special structure. Positioning, clamping and alignment are difficult, and the process route is different from conventional processing methods. It is difficult to guarantee the processing quality of this type of casing with conventional processing methods. Contents of the invention [0003] In order to solve the above-mentioned technical problems, the purpose of the present invention is to provide a processing method and a clamp for a casing, and the specific technical solutions are as follows: [0004] A non-orthogonal structure casing processing method is characterized in that it includes the following step...
