Embodiment Construction

[0023] The present invention will be further described below in conjunction with accompanying drawing.

[0024] like figure 1 As shown, the accuracy detection tool for the intersection hole of the side wall of the nose landing gear of the present invention includes a skeleton 1, a joint support 2, a positioning pin, and inspection pins 4 of various diameter specifications and gaskets 5 of different thickness specifications. The skeleton 1 can be hollow or solid, regular or irregular, and made of metal or non-metal, preferably a material with little deformation. For example, the frame 1 is a frame body, which is made of metal and has a rectangular shape, and the frame body is made of a rectangular tube. In order to facilitate the lifting of the frame 1, at least three legs 8 can be arranged at the bottom of the frame 1, the lower ends of the legs 8 are support ends, the legs 8 are vertically arranged, and the plane where the frame is located is inclined, as figure 1 shown.

Abstract

The invention discloses a nose landing gear side wall intersection point hole precision detection tool and detection method, relates to the field of aircraft assembly and manufacturing, and aims to solve the problems by providing a nose landing gear side wall intersection point hole precision detection tool and detection method. According to the technical scheme, the nose landing gear side wall intersection hole precision detection tool comprises a framework, connector supports, positioning pins, inspection pins of various diameter specifications and gaskets of different thickness specifications, the connector supports are arranged at the four corners of the framework respectively, and the four connector supports are each provided with a pin hole, namely, a first pin hole, a second pin hole, a third pin hole and a fourth pin hole; wherein the first pin hole is provided with a first positioning pin, the second pin hole and the third pin hole are respectively provided with inspection pins, the fourth pin hole is provided with a second positioning pin and an inspection pin, the positioning pins are used for forming detection base points, and the inspection pins are of various specifications and are used for detection. The detection tool and detection method are used for detecting the coaxiality, the location degree and the left and right crotch size of the main intersection point of the nose landing gear and the intersection point of the front supporting rod after product assembly.

Description

technical field [0001] The invention relates to the field of aircraft assembly and manufacturing, in particular to a tool and a method for detecting the coaxiality, position degree, and left and right crotch opening dimensions of the main intersection point of the front landing gear and the intersection point of the front strut. Background technique [0002] The coaxiality, position, and left and right crotch opening dimensions of the main intersection of the front landing gear and the intersection of the front strut have high requirements. After the assembly is completed, the coaxiality and the size of the left and right crotch are generally checked by the coaxiality rod, and the positional degree cannot be checked. Contents of the invention [0003] The first technical problem to be solved by the present invention is to provide a tool for detecting the accuracy of the intersection hole of the side wall of the nose landing gear. [0004] The technical solution adopted by...
