Problems solved by technology

During assembly, because the auxiliary pipe is located outside the radome, the auxiliary pipe blocks the pitot tube bolt installation hole; and the internal operable space is narrow, and the bolt hole of the auxiliary pipe cannot be directly led out from the radome to the auxiliary pipe, so the auxiliary pipe assembly Pitot bolt holes cannot be used as a reference

Embodiment Construction

[0014] In order to further reflect the technical means, creative features, and realized functions of the present invention, the present invention will be described in detail below in conjunction with specific drawings and embodiments.

[0015] Such as figure 1 and figure 2 Shown is the working status of the pitot auxiliary tube installation tool. Among them, 1 is the radome (reference product); 2 is the drill sleeve; 3 is the auxiliary positioning plate; 4 is the auxiliary pipe (the product to be installed); 5 is the positioning shaft; 6 is the bushing hole of the drill sleeve; 7 is the auxiliary clamping bolt hole.

[0016] The positioning shaft 5 is a shaft-shaped part with a cylindrical boss. When the product is working, it is located inside the auxiliary tube. The diameter of the front section is the same as the inner diameter of the auxiliary tube of the assembled product, and the diameter of the rear end is the same as the pitot tube installation hole of the radome 1....

Abstract

The invention discloses an installation tool for an auxiliary pipe of an airspeed pipe. The installation tool mainly comprises a locating shaft, a drill bushing and an auxiliary locating plate. The locating shaft is a shaft-shaped part with a cylindrical boss. The drill bushing is of a cylindrical structure and comprises a drilling sleeve and a flange plate. The auxiliary locating plate is fixed to one end of the flange structure of the drill bushing and is provided with a plumb line. According to the invention, the assembly requirement for coaxiality between the auxiliary pipe and an airspeed pipe installation hole of a radome is met, the position uniformity of bolt holes, connected with the airspeed pipe of the radome, of the auxiliary pipe is guaranteed, and the assembly technology requirement that the symmetry axis of the bolt holes coincides with the symmetry plane of a fuselage is met.

Description

Background technique [0001] The invention relates to the technical field of aircraft assembly, in particular to a pitot auxiliary tube installation tool. Background technique [0002] The pitot auxiliary tube is located at the front end of the aircraft radome, and is mainly used to install a standard pitot tube on the aircraft to test the working performance of the aircraft's atmospheric system. When installing the Pitot Auxiliary Tube, bolt installation holes with the same hole position must be drilled on the auxiliary tube according to the Pitot Tube installation hole of the radome, and the axes of the two upper bolt holes are located on the plane of symmetry of the aircraft. After assembly, ensure that The coaxiality deviation between its axis and the axis of the installation hole of the pitot tube of the radome is less than Φ1.5mm. In the assembly of the pitot auxiliary pipe, there are the following technical defects, which cannot meet the assembly requirements: [000...
