Description
Technical field
The present invention relates to screw and nut dismantling technology fields, and in particular to a kind of screw on curved surface, nut
Extracting tool and application method.
Background technique
The Large-Scale Equipments such as aircraft, high-speed rail surface uses a large amount of screws and is attached, but because environmental corrosion, glue spiral shell seal work
The factors such as skill, the screw on Large-Scale Equipment surface easily occur screw thread position and get rusty, seal that gluing is viscous, ailhead recess etch shoals
Phenomenon increases and is screwed power, reduces the torque that screwdriver can apply, often results in screw and be difficult to the problem of dismantling, directly
Influence these Large-Scale Equipment maintenance efficiencies and quality.
Currently, the provision for disengagement of common screw has: (1) Chinese patent CN03272135.8 mainly utilizes lever former
Reason increases the normal pressure of screwdriver, and the binding force between screw thread is overcome by force application arm, screwdriver, the method for unscrewing screw,
But this method must remove at least one screw that can be unscrewed in tools range, could mention by the screw hole to lever
For fulcrum, maintenance load is not only increased, and unscrews the screw hole that should not be repaired and comes as fulcrum using the screw hole,
The tooth form intensity of Large-Scale Equipment surface texture intensity and fulcrum threaded hole will be destroyed.(2) Chinese patent CN202271352U,
It mainly cuts, tap using engraving tool, the strong destructiveness method for dismounting of drill tapping again and punching pin punching etc., but since aircraft, high-speed rail etc. are big
The screw of type equipment is made of high-intensitive and high rigidity metal material mostly, and it is big to implement difficulty, troublesome in poeration and take
When it is laborious, especially do so be very easy to damage large surfaces structural strength, influence aerodynamic configuration, reduce large scale equipment
Overall structural strength brings very big security risk to the Large-Scale Equipment of these high-speed cruisings.Therefore, it is badly in need of in the industry a kind of novel
The extracting tool and application method for screw, nut on smooth surface.
Summary of the invention
