Description
Technical field
This utility model is related to a kind of nut dismounting tool, especially a kind of suitable for connecing in narrow space dismounting six angle pipes
The instrument of nut, belongs to hand-operated tools technical field.
Background technology
The environmental control system conduit of aircraft nacelle, draws from a rectangle lid of fuselage, and one end is connected to
In aircraft skin outlet, the other end is connected with engine system compressor by hexagonal union nut.Due to environmental control system conduit
Hexagonal union nut diameter dimension it is larger, and with peripheral appendix member be spaced less, dismounting operation narrow space, to environmental control system
When conduit is keeped in repair, adopt common wrench normally cannot fix to complete to be threaded in or out action, and the lid chi of aircraft fuselage
Only about 65 degree or so of the very little angle for limiting rotation every time, further increases the dismounting difficulty of hexagonal union nut.
For the dismounting problem of above-mentioned hexagonal union nut, people's generally employing will solve cutter head alignment hexagonal union nut side
Edge, then solution knife handle is tapped by hammer so as to the method that hexagonal union nut is impacted in loose or tight direction, thereby result in six
Cornue connected nut is scarred after decomposing or assembling, and causes the environmental control system conduit of aircraft nacelle big during repairing
Amount hexagonal union nut is scrapped, and loses huge.
Utility model content
This utility model provides a kind of narrow space hexagonal union nut dismantling device, it is intended to reduce aircraft nacelle
The scrappage of hexagonal union nut in environmental control system conduit repair procedures, reduces maintenance cost.
For achieving the above object, the technical scheme adopted by this utility model is：
A kind of narrow space hexagonal union nut dismantling device, including rotating fixed disk and special spanner；The rotation is solid
Price fixing is disc structure, the hexagon through hole that center portion position setting wherein is matched with outer six prismatic surfaces of hexagonal union nut, and
Its peripheral position is uniformly arranged location hole；The special spanner is made up of crescent fixing head and operation handle, solid in crescent
Determine on head, to be symmetrical arranged two alignment pins, the alignment pin is matched with the location hole on rotating fixed disk.
Above-mentioned narrow space hexagonal union nut dismantling device, the positioning hole number on the rotating fixed disk are six,
It is divided into three groups, each of which group includes two location holes for being arranged symmetrically in rotating fixed disk diameter two ends.
Above-mentioned narrow space hexagonal union nut dismantling device, the positioning bore dia D with the difference of alignment pin diameter d is
0.5mm, i.e. D-d=0.5mm.
Above-mentioned narrow space hexagonal union nut dismantling device, the operation handle of the special spanner is L-type structure, is passed through
The horizontal arm of L-type structure is connected as a single entity with crescent fixing head middle part.
This utility model after using above-mentioned technical proposal, the effect with following technological progress：
This utility model is performing the decomposition of narrow space hexagonal union nut conduit or assembling behaviour in aircraft nacelle
When making, rotating fixed disk can be penetrated from the other end of conduit, supravasal six angle pipes are sleeved on by hexagon through hole and connects spiral shell
On mother, then two alignment pins in the crescent fixing head of special spanner are inserted on rotating fixed disks in one group of location hole, it is suitable
Hour hands or rotate counterclockwise special spanner, drive hexagonal union nut to be threaded in or out by rotating fixed disk, thus achieve
Conduit hexagonal union nut not only reduces aircraft nacelle environmental control system conduit and repaiies in the installation and decomposition of narrow space
The scrappage of hexagonal union nut during reason, reduces maintenance cost, and significantly improves dismounting quality and disassembly efficiency.
