Abstract
The utility model relates to a take out instrument of fracture screw tap, including taking out pincers, connecting the body, connect body one end fixedly connected with and take out pincers, take out pincers and be four lamella structures, take out the flute phase -match that clamps with the screw tap, the connection body is the columnar structure, and the centre is equipped with the through -hole. The advantage is: can take out cracked straight flute screw tap under the condition of not haring the screw thread through this instrument. Take out pincers and adopt four lamella structures flute phase -match can be better and the screw tap, be convenient for take out the screw tap. Utilize the welding rod light disconnected screw tap of back -outing of gaining in strength, can take out the screw tap of twisting the dynamic resistance great. This instrument overall structure is simple, convenient operation, and is safe, reliable, and low cost has greatly saved the time of taking out the fracture screw tap moreover, has reduced intensity of labour, has improved production efficiency.
Description
Technical field
This utility model relates to a kind of instrument taking out fracture screw tap.
Background technology
Through conventional tap tapping in the work of pincers worker, as long as slightly accidentally, screw tap just fractures in hole.The screw tap taking out fracture is cumbersome, and the section typically by electric weld handle broken tap piles height, then welds iron rod, then slowly pulls screw tap and is drawn off；Or when screw tap breaks at through hole, slowly screw tap is melted with gas welding and the screw tap of fracture is taken out.Both approaches is likely to cause screwed hole to destroy, when screw tap break in blind hole deeper time, both the above method is unsuitable for.
Summary of the invention
For overcoming the deficiencies in the prior art, the purpose of this utility model is to provide a kind of instrument taking out fracture screw tap, takes out fracture screw tap under the premise that screwed hole does not damage, and to be applicable to screwed hole be blind hole or the deeper situation of screw tap breaking part.
For achieving the above object, this utility model is achieved through the following technical solutions:
A kind of instrument taking out fracture screw tap, including forceps, connects body, connects body one end and is fixedly connected with forceps, and forceps is four valve structures, and the flute of forceps and screw tap matches, and connection body is column structure, and centre is provided with through hole.
The described connection body other end is hexagon head structure.
Described connection body and forceps are integral type structure.
It is provided with welding rod in described through hole.
Compared with prior art, the beneficial effects of the utility model are:
When not damaging screw thread, the straight slot screw tap of fracture can be taken out by this instrument.Forceps adopts four valve structures better to match with the flute of screw tap, it is simple to take out screw tap.Utilize welding rod to increase intensity easily to back-out broken tap, can take out turning the bigger screw tap of resistance.This instrument overall structure is simple, easy to operate, safe and reliable, and with low cost, has been greatly saved the time taking out fracture screw tap, has reduced labor intensity, improve production efficiency.
Accompanying drawing explanation
Fig. 1 is front view of the present utility model.
Fig. 2 is side view of the present utility model.
In figure: 1-forceps 2-connects body 3-through hole 4-hexagon head structure.
Detailed description of the invention
Below in conjunction with Figure of description, this utility model is described in detail, it should be noted that enforcement of the present utility model is not limited to following embodiment.
See Fig. 1, Fig. 2, a kind of instrument taking out fracture screw tap, including forceps 1, connect body 2, connecting body 2 one end and be fixedly connected with forceps 1, forceps 1 is four valve structures, and the groove of forceps 1 and screw tap matches, connecting body 2 is column structure, and centre is provided with through hole 3.
Wherein, connecting body 2 other end is hexagon head structure 4, in order to turn with spanner.Connecting body 2 with forceps 1 is integral type structure.
Also can be provided with welding rod in through hole 3, utilize welding rod screw tap and connection body 2 to be welded, screw tap deeper for breaking part is taken out.
This instrument can be manufactured by outer-hexagonal bolt, stay bolt car with fracture screw tap same size is removed thread surface, in bolt shaft upwards holes drilled through 3, four valve structures with matching are milled out as forceps 1 according to the shape of screw tap flute at bolt end, making forceps 1 insert the space between flute and the screwed hole of fracture screw tap, such instrument has just been manufactured.
During construction, before taking broken tap, broken tap in screwed hole must be considered to be worth doing and other iron filings are removed clean, then add machine oil, to reduce the frictional force taking out screw tap, forceps 1 is directed at the flute of screw tap, insert in screwed hole and ensure vertical, direct wrenching bolt head when resistance is little time, utilizes forceps 1 to turn broken tap, is taken out by broken tap；When resistance is bigger, by welding rod through through hole 3, body 2 and broken tap firm welding will be connected, and increase intensity and easily back-out broken tap.
The straight slot screw tap of fracture can be taken out when not damaging screw thread by this utility model by this instrument.Forceps adopts four valve structures better to match with the flute of screw tap, it is simple to take out screw tap.Utilize welding rod to increase intensity easily to back-out broken tap, can take out turning the bigger screw tap of resistance.This instrument overall structure is simple, easy to operate, safe and reliable, and with low cost, has been greatly saved the time taking out fracture screw tap, has reduced labor intensity, improve production efficiency.
