Description
Technical field
The utility model is related to a kind of bushing dismounting structure, the bottom outlet that is particularly suitable for bushing installation site be stepped hole or
The bushing dismounting structure of blind hole.
Background technology
When bushing installation bottom outlet is stepped hole or blind hole, general bushing dismounting tool is to utilize several claws by bushing
It extracts, claw is difficult to keep synchronous stress, claw easy fracture, bottom outlet rapid wear when operation.
Invention content
The purpose of this utility model is to provide a kind of bushing dismounting structure, may be implemented bushing installation bottom outlet be stepped hole or
The dismounting of bushing when blind hole, and with synchronous stress, to ensure that bushing is not damaged because of unbalance stress.
The specific technical solution of the utility model is, the bushing dismounting structure include fixing sleeve, straight pin, flabellum,
Rotary shaft, guide pin, the rotary shaft bottom are provided with the pallet that diameter is less than bushing bore dia, fixing sleeve clearance fit peace
On the rotary shaft, bottom is provided with turntable identical with rotary shaft bottom tray diameter to dress, between the pallet and turntable
It is provided with the identical flabellum of multiple shapes, each flabellum is mounted on the turntable of fixing sleeve by straight pin and can be around straight pin
Rotation, the bottom end of guide pin are fixed on the pallet of rotary shaft bottom, and top is located in the guide groove of flabellum, the guide pin
When being rotated around rotary shaft, by the guiding of guide groove, flabellum is made to be rotated and closure or expansion around straight pin, when flabellum is closed,
All flabellums are respectively positioned between pallet and turntable；When flabellum is unfolded, the subregion of flabellum is stretched out between pallet and turntable.
When the utility model is used, rotation rotary shaft, guide pin does circumferential movement with rotary shaft, while guide pin passes through
Guide groove drives flabellum to be rotated around straight pin, and flabellum is made to be closed；Then this structure is mounted on component to be removed, by flabellum
Position is placed in bushing lower part to be removed, and fixing sleeve is fixed, and rotates rotary shaft, flabellum is made to be unfolded, be stuck in sleeve, and can be with
Bushing soffit plane contacts, and uniformly exerts a force, realizes the steady dismounting of bushing, ensure that disassembly process bushing uniform force, avoid
Damage bottom outlet.The utility model to realize the easy to disassemble of bushing, and synchronizes stress by the folding of flabellum, to
Ensure that bushing is not damaged because of unbalance stress.
