Abstract

The utility model relates to a special tool for dismounting a large bolt. The utility model comprises a remover body and a screw top rod; the remover body is of an U-shaped handlebar shape; the end at one side of the remover body is an open spanner; the end at the other side of the remover body is provided with a screwed hole; the screw top rod can be assembled into the screwed hole; the remover utilizes the working principle of a screw jack to be capable of dismounting the large bolt which is firmly connected in a narrow space, and is a special tool for repairing and maintaining the large apparatuses like airplanes.

Description

A kind of Bolt dismantling device
Technical field
The utility model belongs to the machine tool class, is not particularly a kind ofly opening wide the specific purpose tool that is used for dismantling screw under the environment.
Background technology
Durable large product such as aircraft is when safeguarding; usually need to dismantle some connecting bolts; and these bolts are because long-term use or because of interference engagement is difficult to decompose, more particularly in other structures of not opening wide around position dismounting connecting bolt regular meeting's damage often bolt.
Summary of the invention
The purpose of this utility model is to provide the specific purpose tool of a kind of energy bolt for convenience detach.
For achieving the above object, the technical solution of the utility model is: the Bolt dismantling device is made up of stripping attachment body and threaded mandrel, the body of stripping attachment is a kind of ∪ type handle-shaped, one side head of stripping attachment body is an open-end wrench, the opposite side termination of stripping attachment body is provided with a screwed hole, threaded mandrel can be assembled in this screwed hole, and the screwed hole of stripping attachment body one side and the open-end wrench of opposite side are on the same central axis.
During use, by the location, two ends that stripping attachment body openings at two ends spanner and threaded mandrel will wait to tear open bolt, the open-end wrench of stripping attachment be pressed on wait to tear open bolt end around tear bolt open and lead in order to bear the propulsive force of threaded mandrel, to treat simultaneously; The top that the opposite side termination of waiting to tear open bolt is disassembled the threaded mandrel of device compresses, rotate threaded mandrel with spanner, threaded mandrel just moves with respect to the stripping attachment body, and roof pressure waits to tear open bolt simultaneously along the displacement of roof pressure direction, removes from original bolt hole thereby will wait to tear open bolt.
The advantage of the utility model Bolt dismantling device is, and is simple and reasonable, utilizes the operation principle of screw thread jack, in narrow space, can easily dismantle and connects fastening large-scale bolt, is the specific purpose tool of large-scale apparatus maintenance and repair such as aircraft.
Below in conjunction with embodiment this application is described in further detail:
Description of drawings:
Accompanying drawing is the structural representation of the utility model Bolt dismantling device
Number description: 1 open-end wrench, 2 top covers, 3 screwed holes, 4 threaded mandrels, 5 bodies
The embodiment explanation
Referring to accompanying drawing, Bolt dismantling device body 5 is the enough ∪ type handles of a kind of rigidity, one end of ∪ type body is designed crotched open-end wrench 1, the other end of ∪ type body is provided with screwed hole 3, other has threaded mandrel 4 to be screwed onto in the screwed hole 3 of ∪ type body, the top cover 2 of threaded mandrel 4 is designed to six rib round end shapes in the enforcement, and top cover and threaded mandrel are one.
During use, select the suitable Bolt dismantling device of size dimension for use, the ∪ type body of stripping attachment is stuck in by waiting to tear open bolted structure both sides, the open-end wrench 1 of stripping attachment will be waited to tear open the end encirclement of bolt and be pressed on and wait to tear open on the bolt structure on every side, the rotation threaded mandrel makes the top cover 2 of threaded mandrel be pressed on the other end of waiting to tear open bolt, continues the rotation threaded mandrel until will wait that tearing bolt open withdraws from from the connecting hole of structure.
