Description
Technical field
This utility model relates to a kind of disassembling fixture, especially a kind of Bolt dismantling frock.
Background technology
At present, bolt is not owing to having six square head structures, therefore, it is impossible to use general spanner to carry out dismantling and installation exercise,
Also can be because of dismantling mode improperly and instrument causes the damage of bolt itself and instrument.
Summary of the invention
For weak point present in the problems referred to above, this utility model provides one can keep away when dismantling bolt
Exempt from bolt itself and instrument are caused the Bolt dismantling frock of damage.
For achieving the above object, this utility model provides a kind of Bolt dismantling frock, sheathed including outer sleeve (5), bolt
Assembly and rocking bar (6), the sheathed assembly of described bolt is assemblied in the inside of described outer sleeve (5), and described rocking bar (6) is assemblied in described
The bottom of outer sleeve (5), is provided with identical with the shape of bolt (1) on the sheathed assembly of described bolt and is used for overlapping bolt (1)
If through hole a (32) therein.
Above-mentioned Bolt dismantling frock, wherein, the sheathed assembly of described bolt use thread connecting mode be assemblied in described outside
The inside of sleeve (5).
Above-mentioned Bolt dismantling frock, wherein, the inside of described outer sleeve (5) is provided with skewed internal face, at inwall
Face is provided with skewed oblique screw thread (4).
Above-mentioned Bolt dismantling frock, wherein, the sheathed assembly of described bolt is by interior contact block (2) and the soft support in inside
(3) constituting, described interior contact block (2) is arranged on the inside of the soft support in described inside (3), and the soft support in described inside (3) is not
The loop configuration of Guan Bi.
Above-mentioned Bolt dismantling frock, wherein, the soft support in described inside (3) is made up of three supports (31), at described
The outside wall surface of frame (31) is provided with oblique screw thread (4), and the arcuate structure that internal face is inner concavity of described support (31), at described
Offer on frame (31) inside it and for the soft support in described inside (3) with the through hole worn.
Above-mentioned Bolt dismantling frock, wherein, three described supports (31) be the most equidistantly assemblied in described outside
The inside of sleeve (5).
Compared with prior art, this utility model has the advantage that
This utility model has simple in construction, convenient and reliable, it is simple to the feature carried, and can avoid bolt itself and dismounting
Instrument causes damage.When bolt being dismantled by this utility model, the removal efficiency of bolt can be improved, and will not be right
Bolt itself suffers damage.

Detailed description of the invention
As shown in Figures 1 and 2, Bolt dismantling frock provided by the utility model, including sheathed group of outer sleeve 5, bolt
Part and rocking bar 6, the sheathed assembly of bolt is assemblied in the inside of outer sleeve 5, and rocking bar 6 is assemblied in the bottom of outer sleeve 5, sheathed at bolt
Assembly is provided with identical with the shape of bolt 1 and for by sheathed for bolt 1 through hole a32 therein.
In the present embodiment, outer sleeve 5 is cylindrical structural.
The sheathed assembly of bolt uses thread connecting mode to be assemblied in the inside of outer sleeve 5.
The inside of outer sleeve 5 is provided with skewed internal face, is provided with skewed oblique screw thread 4 on internal face.
In the present embodiment, the sheathed assembly of bolt is made up of the soft support in interior contact block 2 and inside 3.
Wherein, interior contact block 2 is arranged on the inside of internal soft support 3, and internal soft support 3 is inc ring junction
Structure.
Internal soft support 3 is made up of three supports 31, and three supports 31 are the most equidistantly assemblied in outer sleeve 5
Inside.
It addition, be provided with oblique screw thread 4 in the outside wall surface of support 31, this oblique screw thread is oblique be arranged on outer sleeve internal face
Screw thread matches, so that three supports fit on outer sleeve with interior contact is packaged.
It addition, the internal face of support 31 is the arcuate structure of inner concavity, the internal face of three supports is to be formed for sheathed
The through hole a32 of bolt.
Support 31 offer inside through it and (figure do not show with the through hole worn for internal soft support 3
Go out).
Owing to internal soft support 3 is inc loop configuration, therefore, when the spacing of interior contact block reduces, interior
Portion's soft support circle diminishes, and does not hinder the motion of interior contact block.
Lower position at outer sleeve 5 is further opened with a rocking bar perforating 7 through inside, and one end of rocking bar 6 is passed through
It is through in rocking bar perforating 7, thus is assemblied on outer sleeve 5.
Principle of the present utility model is as follows:
Rotating rocker, drives outer sleeve to rotate.Due to interior contact block and outer sleeve threaded engagement, outer sleeve can after rotating
So that interior contact block annular diameter reduces, it is that interior contact block is the most close.When interior contact block and threaded bolt contacts it
After, it is rotated further rocking bar, along with the reduction of interior contact block spacing, between interior contact block and bolt, contact becomes tight, makes contact
Pressure just increases, and frictional force increases, and during until the torque that frictional force produces unscrews torque more than bolt, bolt is just unscrewed, and reaches
The purpose of demounting bolt.
When demounting bolt, first according to Bolt sizes coarse adjustment interior contact block spacing so that it is can touch at screw thread and be
Only.Concrete grammar is as follows: put in outer sleeve by interior contact block, and rotating inner part contact block makes interior contact block spacing subtract
Little, until bolt can be arrived basis.Then bolt is inserted in interior contact block, rotate and lengthen rocking bar, to reach to dismantle purpose.
These are only preferred embodiment of the present utility model, be merely illustrative for invention, and nonrestrictive.
Those skilled in the art understands, it can be carried out many changes, revise in the spirit and scope that invention claim is limited,
Even equivalence, but fall within protection domain of the present utility model.
