Problems solved by technology
Since the assembly position of the bearing bush 10 is a closed space with a complex structure, it is very easy to cause damage to the body 8 and the body of the bearing bush 10 by using the existing common disassembly tools
[0003] As we all know, all parts installed on the aircraft have very strict quality requirements, and the price is very expensive, and the damage of parts will bring huge economic losses. Tooling becomes imperative for aircraft maintenance businesses

The invention provides a special tool for disassembling a bearing bushing in a blind hole, and belongs to the technical field of hand-operated tools. The tool comprises a pull rod screw rod, hook assemblies, hook mounting base assemblies, a supporting part, a drawing rod and a handlebar. The hook mounting base assemblies are assembled at the front end of the pull rod screw rod in a matched mode, the drawing rod is arranged at the rear end of the pull rod screw rod to form a screw rod nut transmission mechanism, each hook assembly is installed in the corresponding hook mounting base assembly in a hinged mode, and the hook mounting base assemblies are sleeved with the supporting part; when the bearing bushing in the blind hole is disassembled, the front end of the supporting part is tightly pressed on the end face of a bearing hole in a machine body, the drawing rod is arranged at the rear end of the supporting part, and the supporting part provides supporting counter force for the drawing rod; the handlebar is installed at the rear end of the drawing rod. The tool has the advantages of being accurate in positioning and convenient to operate, the bearing bushing in the blind hole can be disassembled perfectly, and working efficiency is improved.
Description
technical field [0001] The invention relates to a tool for removing a bearing bush, in particular to a special tool for removing a bearing bush in a blind hole, which belongs to the technical field of hand tools. Background technique [0002] as attached figure 1 As shown, in the aircraft body 8 in the maintenance process, after the wings are removed, it is a difficult problem to dismantle the bearing bushing 10 in the blind hole 9 inside the fuselage. Since the assembly position of the bearing bush 10 is a closed space with a complex structure, it is very easy to cause damage to the body 8 and the body of the bearing bush 10 by using existing common dismounting tools. [0003] As we all know, all parts installed on the aircraft have very strict quality requirements, and the price is very expensive, and the damage of parts will bring huge economic losses. Tools have become a top priority for aircraft maintenance companies. Contents of the invention [0004] The object o...
