Description
Technical field
The present invention relates to the technical field of repair of machine instrument, particularly to a kind of dismountable type bolt extractor.
Background technology
When equipment or machine are checked, will often find that the bolt of fracture in screw, and take out at screw
The bolt of interior fracture, relatively difficult.Traditional removing method is to be polished flat by the end face of the bolt of fracture, then chooses suitably
The fluted drill of specification, at one aperture of bolt fracture face centre drill, then inserts bolt extractor in aperture, clamps with adjustable wrench
The square toes at bolt extractor top, firmly rotate counterclockwise, thus drive and break at the bolt in equipment or machine, are taken
Go out.
The cross-sectional area of traditional bolt extractor is little, and its intensity is the highest, when axis and the fracture spiral shell of bolt extractor
When stud shaft line is inconsistent, when firmly rotating, bolt extractor easily ruptures, and especially bolt extractor breaks at bolt end face
During center, cause the difficulty taking out break bolt.
Summary of the invention
It is an object of the invention to, there is drawbacks described above for solving traditional bolt extractor, and then provide a kind of removable
Unload type bolt extractor, comprising: screw rod, adapter, basis fixed block, the first bolt and the second bolt；At base
Symmetrical two screwed holes in the plane of plinth fixed block, and the axis of each screwed hole is each perpendicular to the flat of this basis fixed block
Face；Described first bolt and described second bolt respectively with described basis fixed block two screwed holes coordinate,
A through hole is offered in the middle, side of described basis fixed block, and one end of described adapter is connected with this through hole, described adapter
The intrinsic tooth set of the other end, and this tooth is arranged with internal spiral threads, and the centre position of described screw rod is provided with screw, will
Described screw rod vertically screws in the other end of described adapter.
The intrinsic square toes in top of described screw rod, the lower end of described screw rod is cone-type spiral screw thread.
The interior spiral shell of another end tooth set of the hand of spiral of the screw of described screw rod middle position and described adapter
The hand of spiral of rotation screw thread is consistent.
The diameter of described through hole is identical with the diameter of one end of described adapter.
Distance between the two ends of described adapter becomes big or diminishes.
The axis of described through hole is respectively perpendicular to the axis of two screwed holes of described basis fixed block.
During taking-up breaks at the break bolt in equipment or machine, first the end face of break bolt is polished flat
Whole, then choose suitable fluted drill, at one aperture of end face centre drill of break bolt, by this dismountable type bolt extractor
The cone of lower end of this screw rod creep at the central small hole of break bolt end face, and guarantee axis and the break bolt of this screw rod
Axis consistent, then by this is detachable by described first bolt and described second bolt for described basis fixed block
Component near type bolt extractor and break bolt is fixed together, and uses adjustable wrench to clamp the square toes of this screw rod, counterclockwise
Rotate this screw rod so that this screw rod combines with break bolt, continue to rotate counterclockwise, break bolt is taken out.
It is an advantage of the current invention that: use the mode that each unit construction connects, convenient disassembly, it is simple to carry, it is to avoid spiral shell
The axis of bar and the inconsistent inclination caused of the axis of break bolt, greatly reduce the risk that fracture occurs when screw rod reverses,
Add the service life of equipment or machine, add security performance；Have employed basis fixed block and the first, the second bolt
Combination application, the matrix of dismountable type bolt extractor with equipment or machine is fixed together, reduces in break bolt
During taking-up, owing to manual operation causes unbalance stress, there is the risk of screw rod fracture.

Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention is described in further detail.
As illustrated in fig. 1 and 2, the present invention provides a kind of dismountable type bolt extractor, comprising: screw rod 1, adapter 3, base
Plinth fixed block 4, the first bolt 5 and the second bolt 11；Symmetrical two spiral shells in the plane 12 of basis fixed block
Pit 9, and the axis of each screwed hole 9 is each perpendicular to the plane 12 of this basis fixed block；Described first bolt 5 and described
Second bolt 11 two screwed holes with described basis fixed block 4 respectively coordinate, in the side of described basic fixed block 4
Between place offer a through hole 10, as it is shown in figure 5, the lower end of described adapter 3 is connected with this through hole 10, the upper end of described adapter 3
An intrinsic tooth overlaps 2, and this tooth set 2 is provided with female thread, and the centre of described screw rod 1 is provided with screw 7, is erected by described screw rod 1
Direct rotary enters the upper end of described adapter 3.
As it is shown on figure 3, the intrinsic square toes 6 in the top of described screw rod 1, the lower end of described screw rod 1 is cone-type spiral screw thread 8.
The hand of spiral of the screw 7 of described screw rod 1 middle position is interior with the upper end tooth of described adapter 3 set 2
The hand of spiral of screw is consistent.
The diameter of described through hole 10 is identical with the diameter of the lower end of described adapter 3.
