Abstract
The utility model relates to a kind of extracting tools of blind hole neck bush, including rotatable chela, fixed chela, pull rod shaft, supporting plate, force nut, fixed chela is fixedly mounted on the bottom of pull rod shaft, chela setting be can be rotated on fixed chela and can be rotated around pull rod shaft, the rotatable chela and fixed chela end to pull rod axis center distance between bushing internal-and external diameter to be removed, the upper surface and axle sleeve bottom to be removed that can be rotated chela and fixed chela end face cooperate, the pull rod shaft passes through supporting plate, and is equipped with force nut.The utility model, by the effect of force nut and chela, uniformly lifts bushing upwards, realizes neck bush and its mating parts blind hole is not destroyed in disassembly process in the case where the not suitable point of application.
Description
Technical field
The utility model relates to a kind of extracting tool, especially a kind of extracting tool of blind hole neck bush.
Background technique
During existing blind hole neck bush, since pressing tightness is larger and does not have the suitable point of application, machine is generallyd use
Tool processing destroys the method for dismounting of bushing, is easy to damage damage to matrix.
Summary of the invention
The purpose of this utility model be design one kind can in the unsuitable point of application, bushing and phase accessory pressing tightness compared with
Greatly, and phase accessory is the inner liner dismounting tool of blind hole, and neck bush and its mating parts blind hole can be realized in disassembly process
In do not destroyed.
The technical solution of the utility model is：A kind of extracting tool of blind hole neck bush includes that can be rotated chela, grips pincers
Pawl, pull rod shaft, supporting plate, force nut, fixed chela are fixedly mounted on the bottom of pull rod shaft, can be rotated chela and are arranged in grips pincers
It can rotate on pawl and around pull rod shaft, the distance of the rotatable chela and fixed chela end to pull rod axis center is between wait tear open
It unloads between bushing internal-and external diameter, the upper surface and sleeve to be removed that can be rotated chela and fixed chela end face cooperate, described
Pull rod shaft passes through supporting plate, and is equipped with force nut.Being located in pull rod shaft, which can be rotated above chela, is provided with axial pulling pin.Institute
The upper surface of the rotation chela and fixed chela end face stated is inclined-plane.
When the utility model is used, will first can be rotated chela is overlapped with fixed chela or is located at the same side, it is put into wait tear open
Bushing lower end surface is unloaded, adjusts and can be rotated the other end that chela is located at fixed chela, supporting plate is fixed or is arranged on matrix top, is twisted
Tight upper end force nut drives chela to post and fix with bush end face to be removed, continues through force nut and supporting plate for bushing
It disassembles and is not exposed to any destruction.The utility model passes through force nut and pincers in the case where the not suitable point of application
The effect of pawl uniformly lifts bushing upwards, realizes neck bush and its mating parts blind hole is not destroyed in disassembly process.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model；
Two chela position views when Fig. 2 is in working condition；
Two chela position views when Fig. 3 is installation condition；
Fig. 4 is another improvement structural schematic diagram.
Specific embodiment
As shown, a kind of extracting tool of blind hole neck bush includes that can be rotated chela 1, fixed chela 2, pull rod shaft 3, branch
Plate 4, force nut 5, fixed chela 2 are fixedly mounted on the bottom of pull rod shaft 3, can be rotated chela 1 and are arranged on fixed chela 2 simultaneously
It can be rotated around pull rod shaft 3, the distance at the rotatable chela and fixed 2 end of chela to 3 center of pull rod shaft is between to be removed
Between 6 internal-and external diameter of bushing, the upper surface and 6 bottom of bushing to be removed that can be rotated chela 1 and fixed 2 end face of chela cooperate, described
Pull rod shaft 3 pass through supporting plate 4, and be equipped with force nut 5.Being located in pull rod shaft 3, which can be rotated above chela 1, is provided with axis
To pulling pin 7.The upper surface of the rotation chela 1 and fixed 2 end face of chela is inclined-plane.
