Description
Technical field
The invention belongs to screw thread process technical fields, more particularly to a kind of multifunctional safety tap wrench with screw die and make
Use method.
Background technology
Currently, small size screwing tool mainly has tap and die, screw tap is for processing small size internal thread, screw die
For processing small size external screw thread, the auxiliary tool that internal thread machining is carried out for screw tap to be clamped is windeisen, also known as " hinge
Thick stick ", the auxiliary tool that outer bolt processing is carried out for screw die to be clamped is die-stock, and also known as " die handle ", and screw tap is pulled
Hand and die-stock are independent from each other two kinds of spanners always, that is to say, that when needs while carrying tap and die progress spiral shell
When line is processed, it is also necessary to carry windeisen and die-stock simultaneously, this is virtually increasing auxiliary tool
Carrying amount, and for tool manufacturing enterprise, it will necessarily also increase the manufacturing cost of auxiliary tool.
Further more, after the small size hole processing on workpiece is good, fitted bolt part is needed to be tightened under normal conditions,
It necessarily lacks at this time and can't do without this auxiliary tool of screwdriver, that is to say, that while carrying windeisen and die-stock,
Also it has to carry knife of tightening up a screw, causes the carrying amount of auxiliary tool further to increase, can not only occupy limited tool and deposit
Between emptying, the dead weight of a large amount of auxiliary tools can also reduce property easy to carry.
In addition, when screw tap progress internal thread machining is clamped using traditional windeisen, and traditional die-stock is utilized to press from both sides
When holding screw die progress outer bolt processing, often screw tap or screw die damage caused by undue force is processed in particular with screw tap
It when blind threaded, more wants especially careful, because easily screw tap fractures in processing blind hole screw thread, while causing part rejection.
Invention content
In view of the problems of the existing technology, a kind of multifunctional safety tap wrench with screw die of present invention offer and user
Method, which is integrated with the repertoire of windeisen, die-stock and screwdriver for the first time, and is used as windeisen
When, it is further extended to reamer holder and is used, while meeting the screw tap of different size, the clamping of reamer and screw die and exchange；
Only need to carry a set of spanner can meet three kinds of job requirements every time, considerably reduce the carrying amount of auxiliary tool, effectively save
Tool storage space is saved, and the dead weight of auxiliary tool also decreases, property easy to carry has been improved, simultaneously for tool system
It makes for enterprise, can also reduce the manufacturing cost of auxiliary tool；The spanner of the present invention is also equipped with overload protection function, can be effective
It avoids tap and die from being damaged in screw thread process, the proportion of goods damageds of tap and die is greatly lowered.
To achieve the goals above, the present invention adopts the following technical scheme that：A kind of multifunctional safety tap wrench with screw die,
Ontology is clamped including handle body, the first fixed handle, the second fixed handle, flexible handle and tool；Described first fixes hand
Handle and the second fixed handle are arranged on handle body, and the first fixed handle and 180 ° apart of the second fixed handle；
It is provided with force transmission shaft on the handle body, part relief hole is offered at the center of handle body and force transmission shaft；Described
Three-level stepped hole is offered in tool clamping ontology, first order stepped hole is screw die holding holes, and second level stepped hole is screw tap clamp
Hole is held, third level stepped hole is force transmission shaft suit hole；If being distributed on the corresponding tool clamping ontology of the screw die holding holes
Dry plate tooth trip bolt；Ontology screw thread phase is clamped with tool in the threaded hole that described flexible handle one end is clamped by tool on ontology
Even, and the inner end of flexible handle extends in screw tap holding holes, is equipped with screw tap grip block in the inner end of flexible handle, passes through silk
Cone grip block is clamped screw tap end side handle with the cooperation of screw tap holding holes；The force transmission shaft of the handle body is located at tool holder
It holds in the force transmission shaft suit hole of ontology, force transmission shaft and force transmission shaft suit hole clearance fit are clamped in the handle body and tool
