Abstract

The invention discloses a tool for replacing bolts at the external field. The tool is used for disassembling and replacing installation bolts (10) of aero-engines at the external field and at least comprises an arch-shaped supporting plate (1) supported on the installation bolts (10), an extrusion bolt (2) installed at a middle protruding part (11) of the arch-shaped supporting plate (1), and a guide pin (3) arranged between the extrusion bolt (2) and the installation bolts (10). According to the tool for replacing the bolts at the external field, the problem that because the replacement space for the installation bolts of the aero-engines at the external field is small, disassembling tools cannot be fully stretched is solved. The tool is easy to use, greatly lowers the labor intensity and improves the labor efficiency.

Description

technical field [0001] The invention relates to a tool for aero-engine maintenance, in particular to a tool for disassembling and replacing mounting bolts of an aero-engine under field conditions, in particular to a tool for replacing bolts in an out-field. Background technique [0002] Aeroengines used in aircraft usually require regular maintenance and maintenance, and sometimes disassembly and maintenance are required after failure or damage. figure 1 What is shown is a schematic diagram of an assembly structure of an engine, wherein a circle of multiple mounting bolts 10 is arranged around the periphery of the aeroengine, figure 2 show yes figure 1 Schematic diagram of the right side of the mounting structure shown, from figure 1 and figure 2 It can be clearly seen that there are many mounting bolts 10 for engine installation, and there are many supporting and connecting structures around the periphery of the engine, so the space is very narrow. When dismounting th...
