Spot facing tooling for non-horizontal end faces

Abstract

The invention relates to a reaming tool for a non-flat end face. The reaming tool comprises an end face reaming cutter, a fixture positioner, an integral cushion block, a flap cabin side rib and a quick-change bushing, wherein a fixed bushing is arranged on the fixture positioner; the quick-change bushing sleeves and is mounted on the fixed bushing; the fixture positioner is mounted on the integral cushion block; the flap cabin side rib prepositions the integral cushion block by the fixture positioner; the integral cushion block is provided with a boss; meanwhile, the integral cushion block is also provided with a finished part mounting primary hole; a positioning pin is inserted into the finished part mounting primary hole by the fixture positioner so as to position the integral cushion block with the boss; the end face reaming cutter is arranged above the fixed bushing. According to the reaming tool, a mounting process is simplified; the reaming tool is convenient to operate; the problem of a mounting error generated by the case that a gasket needs to be selected according to actually measured data in the mounting process of a flap operation control system is effectively solved; the fussy process of manually selecting the gasket is omitted; meanwhile, an error in the finished part mounting process is also reduced; and the reaming tool not only improves product quality and working efficiency, but also is convenient for maintenance outside a plant.

Description

Technical field [0001] The invention relates to the technical field of aircraft parts assembly, in particular to a countersink tool for non-horizontal end faces. Background technique [0002] The mounting holes for the rear flap control system of large aircraft are assembled in the wing frame according to the frame locator, and the holes are reamed to the installation requirements of the piece, and the measured distance from the mounting surface of the piece to the lower end of the locator shall be recorded. [0003] At the same time, gaskets need to be selected according to the actual measured distance, and this process method not only has a large installation error, the installation process is cumbersome, and the work efficiency is low; and when maintaining outside the factory, it is necessary to record the thickness of the gasket at the location of the installation hole of each component, causing errors The possibility of installation is high, so there are hidden dangers to flig...

Problems solved by technology

[0003] At the same time, gaskets need to be selected according to the measured distance, but this method not only has large installation errors, but also has a cumbersome installation process and low work efficiency; and when maintaining outside the factory, it is necessary to record the thickness of the gasket at the position of the mounting hole of each component, causing errors. The possibility of installation is high, so there is a hidden danger to flight safety
