Technical field
The present invention relates to mechanical field, and in particular to one kind takes out fracture tap tool in blind hole.
Background technology
When with the screw thread of screw tap processing blind hole, often screw tap can be broken in hole master worker for various reasons,
Because screw tap is to be broken in process, therefore mutually extrude, make between being broken screw tap in blind hole and workpiece in itself
It is difficult to be removed into screw tap of the fracture inside blind hole, for this problem, ideal instrument also useless is located at present
Manage this problem.
The content of the invention
To solve deficiency of the prior art, the present invention provides fracture tap tool in a kind of taking-up blind hole, solved existing
There is the technical problem of fracture screw tap taking-up more difficulty in blind hole in technology.
In order to realize above-mentioned target, the present invention adopts the following technical scheme that：
One kind takes out fracture tap tool in blind hole, including central shaft, handle, swivel head and support, the central shaft one
End is provided with blind hole of the section for square, and the section of described swivel head one end is square, and the central shaft passes through the blind hole
One end of swivel head is connected, the other end of the central shaft is provided with the through hole along center Axial and radial, and the handle leads to through described
Hole is used to drive central shaft to drive spin head, and the support is circumferentially uniformly provided with some to be connected to otic placode, each pair otic placode
Supporting leg is connect, the other end of the supporting leg is additionally provided with Work fixing device, for securing the stand to workpiece, the swivel head
The other end is three equally distributed driving levers.
As a kind of prioritization scheme, said workpiece fixing device is Magnetic gauge stand.
As a kind of prioritization scheme, the bottom of foregoing blind hole is additionally provided with magnet, and the magnet is used to hold swivel head.
As a kind of prioritization scheme, the central shaft connection end section of foregoing swivel head is fixed, and the driving lever of the swivel head has
Several specification.
As a kind of prioritization scheme, the yield strength of foregoing driving lever is 960MPa.
As a kind of prioritization scheme, group number, Work fixing device, the supporting leg of foregoing otic placode are three.
The beneficial effect that the present invention is reached：
Central axis is fixed on workpiece surface by the present invention by magnetic table and support, utilizes three driving levers of swivel head
The screw tap and workpiece gap of fracture are inserted into, drives three driving levers of swivel head to drive the screw tap of fracture from by operation handle
Screwed out in processed screw thread, because swivel head is provided with three driving levers, cause swivel head to make in the screw tap of driving fracture
The revolving force of the screw tap of fracture is more uniform, simultaneously as the swivel head in the present invention is replaceable, different swivel heads
Front end driving lever specification is different, and to adapt to the screw tap of different size, therefore the versatility of the present invention is stronger.

Embodiment
The invention will be further described below in conjunction with the accompanying drawings.Following examples are only used for clearly illustrating the present invention
Technical scheme, and can not be limited the scope of the invention with this.
As shown in Figure 1：One kind takes out fracture tap tool in blind hole, including central shaft 1, handle 14, swivel head 3 and support
2, the one end of central shaft 1 is provided with blind hole 11 of the section for square, and the section of the one end of swivel head 3 is square, and central shaft 1 is by blind
Hole 11 connects one end of swivel head 3, and the other end of central shaft 1 is provided with the through hole 13 along center Axial and radial, and handle 14 passes through through hole
13 are used to drive central shaft 1 to drive swivel head 3 to rotate, and support 2 is circumferentially uniformly provided with some equal to otic placode 21, each pair otic placode 21
Connection leg 22, the other end of supporting leg 22 are additionally provided with Work fixing device, for support 2 to be fixed on into workpiece, swivel head 3
The other end is three equally distributed driving levers 31.
Work fixing device is Magnetic gauge stand 23, and Magnetic gauge stand 23 belongs to prior art, the Magnetic gauge stand in the present embodiment
Provided with switch, the regulation of magnetic can be realized by rotary switch.
In order to prevent swivel head from coming off when in use, the bottom of the blind hole 11 of the present embodiment is additionally provided with magnet 12, magnet 12
For holding swivel head 3.
In order to lift the versatility of the present embodiment, the central shaft 1 of swivel head 3 connects end section and fixed, i.e., swivel head 3 is with
The physical dimension of the junction of mandrel 1 is fixed, and the driving lever 31 of swivel head 3 has several specification, the several specification and screw tap axle
Specification to gap is identical.
In order to lift the intensity of driving lever, prevent its using when deform upon, the yield strength of the preferred driving lever 31 of the present embodiment
