Description
Technical field
The utility model relates to machinery to dismount auxiliary tool technology field, especially a kind of turbofan fan blade disassembly dress
It sets.
Background technique
After turbofan has been grown using the time, it is easy to appear abrasion or deformations for fan blade, once occur wearing or deform
It just needs to disassemble fan blade later and place under repair or replacement processing, but fan blade easily deforms in disassembly process
（Fan blade generallys use the manufacture of cast aluminium material）, the taking-up for resulting in fan blade can not be successfully in this way, dismantlement work becomes more difficult
And it is time-consuming and laborious.
Summary of the invention
The purpose of this utility model in place of existing above-mentioned difficulties, is mentioned aiming at turbofan when carrying out fan blade disassembly
It is simple for a kind of design of structure, to fan blade disassembling section fast and easily turbofan fan blade provision for disengagement.
The concrete scheme of the utility model is：A kind of turbofan fan blade provision for disengagement has compression plate, compresses disk center
Place offers through hole, surrounding's symmetric position of through hole set there are two with the threaded mounting hole phase on turbofan fan blade wheel disc
Matched disassembly pulling eye connects bolt equipped with fan blade in the disassembly pulling eye；It is also welded on compression plate around the through hole
Equipped with a triangular support bracket, it is equipped with weighted table at the top center of three-legged supporting frame, is equipped with screw thread pulling eye at weighted table center,
A piece pulling force screw rod is housed in the screw thread pulling eye, which matches with the mounting hole in turbofan fan blade spindle,
The front end of pulling force screw rod passes through the through hole and extends downwardly from the center, is additionally provided with rotation at the top of the pulling force screw rod
Handle.
The working principle of the utility model：When carrying out the fan blade disassembling section of turbofan, first by compression plate and turbine
The fan blade wheel disc of blower is aligned, then fan blade connection bolt is connect tightly with the threaded mounting hole on turbofan fan blade wheel disc
Gu then by the rotation of swing handle, by the mounting hole in pulling force screw rod precession turbofan fan blade spindle, with drawing
The precession of power screw rod is goed deep into, and can use mutual opposition naturally for compression plate together with turbofan fan blade
Reverse ejection takes out fan blade after ejection, and finally pulling force screw rod, fan blade connection bolt are reversely screwed out and dismantled
Get off to complete a fan blade dismantlement work.
The utility model operates with simply, time saving and energy saving, some leftover bits in the production full utilization workshop of device
Production saves cost without singly buying complete set of equipments.
Detailed description of the invention
Fig. 1 is the general structure schematic diagram of the utility model；
Fig. 2 is connection schematic diagram when the utility model is used.
In figure：1-fan blade connection bolt, 2-compression plates, 3-through holes, 4-pulling force screw rods, 5-three-legged supporting frames,
6-weighted tables, 7-swing handles, 8-turbofans, 9-fan blade wheel discs.
Specific embodiment
The utility model is a kind of turbofan fan blade provision for disengagement, has compression plate 2, compresses to offer at disk center and pass through
Perforation 3, surrounding's symmetric position of through hole are set there are two tearing open with what the threaded mounting hole on turbofan fan blade wheel disc 9 matched
Pulling eye is unloaded, fan blade is housed in the disassembly pulling eye and connects bolt 1；Also being welded on compression plate around the through hole has one
Triangular support bracket 5 is equipped with weighted table 6 at the top center of three-legged supporting frame, is equipped with screw thread pulling eye, the spiral shell at weighted table center
A piece pulling force screw rod 4 is housed, which matches with the mounting hole in turbofan fan blade spindle, pulling force spiral shell in line pulling eye
The front end of bar passes through the through hole and extends downwardly from the center, is additionally provided with swing handle 7 at the top of the pulling force screw rod.
When carrying out the fan blade disassembling section of turbofan, first compression plate 2 is aligned with the fan blade wheel disc 9 of turbofan 8,
Fan blade connection bolt 1 is connect fastening with the threaded mounting hole on turbofan fan blade wheel disc again, then passes through swing handle 7
Rotation, by the mounting hole in 4 precession turbofan fan blade spindle of pulling force screw rod, as the precession of pulling force screw rod is goed deep into,
Naturally it can use mutual opposition for compression plate together with turbofan fan blade reverse ejection, when ejection
Fan blade is taken out afterwards, finally pulling force screw rod, fan blade connection bolt are reversely screwed out to disassemble and be completed once
Fan blade dismantlement work.
The utility model operates with simply, time saving and energy saving, some leftover bits in the production full utilization workshop of device
Production saves cost without singly buying complete set of equipments.
