Problems solved by technology
[0008] In order to solve the above-mentioned problems, the invention provides a kind of machining method of the top cover of the air pod of an aircraft, the processing method first solves the problem of selecting the reference plane of the top cover, and formulates the first outer ring and the first outer ring through the selection and processing of the reference plane. The processing steps of the second outer ring, the first signal receiving hole and the second signal receiving hole, and then the first signal receiving hole and the second signal receiving hole are processed by the EU-1000 processing equipment. During the processing, the first outer surface of the top cover Neither the ring nor the second outer ring is deformed, and the machining method is simple and practical

Embodiment Construction
[0034] The invention is a machining method for the top cover of an air pod of an aircraft, and the machining method of the invention can better solve the problems mentioned in the background technology.
[0035] In most cases, the top cover is made of precision casting ZL205A or ZL101A aluminum alloy.
[0036] combine figure 1 , the upper half of the top cover is in the shape of a semi-circular section and the lower half is in the shape of a ring, the upper half of the top cover is referred to as the second outer ring 4 and the lower half is referred to as the first outer ring 3. The first signal receiving hole 1 and the second signal receiving hole 2 are provided on the cross section of the second outer ring 4, and the diameter of the first signal receiving hole 1 is required to be The aperture of the second signal receiving hole 2 is The vertical distance from the lower end face of the first outer ring 3 to the upper end face of the second outer ring 4 is The hole spac...

Abstract
Provided is a machining method of an airplane overhead nacelle top hood. The method comprises the steps of selection of datum planes, marking by a bench worker, rough milling of the first datum plane, machining of a first outer ring and a second outer ring, finish milling of the second datum plane, finish milling of the first datum plane, machining of a first signal receiving hole and a second signal receiving hole, and subsequent treatment. An SK50P digital controlled lathe, a V.M.C-1401 machining device and an EU-1000 four-axle machining device are adopted in the machining method, the coaxiality of the first outer ring and the second ring can be effectively ensured through rough milling of the first datum plane, accurate machining on the first signal receiving hole and the second signal receiving hole can be effectively ensured through finish milling of the first datum plane, rough turning precision and finish turning precision of the first outer ring surface and the second outer ring surface can be effectively ensured through rough milling of the first datum plane, the top hood is free of stress deformation under the tool feeding amount of 10 mm / r, and the machining method is simple and practical.
Description
technical field [0001] The invention belongs to the technical field of machining, in particular to a machining method for the top cover of an air pod of an aircraft. technical background [0002] The top cover is one of the main components of the aircraft air pod. The air pod is mainly composed of a front spherical shell, a rear spherical shell, a fork, a connecting plate and a top cover. The top cover is located at the top of the entire air pod. The top cover and The bottom of the aircraft is connected and fixed. [0003] combine figure 1 , the top half of the precision casting of the top cover is in the shape of a semi-circular section and the lower half is in the shape of a circular ring. There are seven 90° tapered holes at the bottom 6mm. These seven tapered holes are connected to the lower part. The disks are connected, and a first signal receiving hole 1 and a second signal receiving hole 2 are provided on the cross section of the top cover, and the aperture sizes o...
