Description
Technical field
It fractures taking-up tool the utility model relates to mechanical manufacturing field more particularly to a kind of universal type screw tap.
Background technique
In machining, when processing screw thread using screw tap, often encounters screw tap and fracture the situation in workpiece, product
Scrap the loss compared with screw tap for, more make us feeling to regret.Under normal conditions, the silk to fracture in threaded hole is taken out
Cone, the method for taking broken tap have spark erosion machining and welding, and electrical discharge machining is easy to machine away the matrix of part and report
Odd parts, and it is costly, can not process at the scene.Welding is unreliable, often damages components itself.For fractureing in workpiece
The shallower screw tap of middle threaded hole according to circumstances mostly uses some easy Screw tap taking-out devices, such as uses clamp or homemade steel
Broken tap is back-outed to come in silk insertion screw tap slot.Then due to using the model of screw tap different, its diameter is different, homemade
Some simple broken tap withdrawing device difficulty or ease guarantee to take out the broken tap of different models, and since to twist power direction poor by user
Different, broken tap is easily damaged the inner hole thread attacked during taking-up.
The utility model patent that domestic applications number are 201220053672 discloses a kind of broken tap taking-up tool, it is by pressing from both sides
Tight device and fast swiveling mechanism composition；Clamping device is by clamping jaw, drill body, gear ring, mandril, compressed spring, the flexible adjustment of mandril
Nut and push rod composition；Fast swiveling mechanism by sleeve barrel spanner, ratchet mechanism, tighten handle and form；Ratchet mechanism is by ratchet, reset
Spring, pawl are constituted；Clamping device is provided with the spring being made of mandril, compressed spring, the flexible adjusting nut of mandril and push rod
Collet automatic blanking mechanism；Mandril is mounted on fixed handle centre, and the diameter of mandril is more smaller than the clamping diameter of collet；Top
The subsequent minor diameter position of bar has been equipped with the compressed spring for extruding push rod effect.The tool has easy to use, reliable operation,
It can not be taken out by hand the advantages that fractureing the screw tap of different-diameter in threaded hole in the case where defective work piece, shortcoming is knot
Structure is complicated.
Utility model content
It fractures taking-up tool the purpose of the utility model is to provide a kind of universal type screw tap, overcome the deficiencies in the prior art,
It solves the problems, such as to take out difficulty after screw tap fractures, workpiece is avoided to scrap, reduce waste of raw materials, reach and save cost, shorten life
The purpose for producing the period, improving efficiency, and then improve production and processing working hour.
To achieve the above object, the utility model is achieved through the following technical solutions:
Universal type screw tap fractures taking-up tool, which is characterized in that its structure is one section of body of rod, and one end of the body of rod is clamping
End, the other end of the body of rod are ratchet end, and the outer diameter of the ratchet is one in complete array of sizes, and the ratchet is along the bar
For the extending direction of body circumferentially to being uniformly distributed, the quantity of the ratchet is 2~4, and the shape of the ratchet is zigzag, circle
Any one of cylindricality or elliptical cylinder-shape.
The height of the ratchet is 8~15mm.
The clamping end is any one of triangular prism shaped, four prism type or hexagon, and geomery is stayed with corresponding
Metal plate hand or ratchet spanner match.
The high-intensitive tool steel rod elements that the body of rod is 50 degree of Rockwell hardness or more.
Compared with prior art, the utility model has the beneficial effects that
Solve the problems, such as to take out difficulty after screw tap fractures, workpiece avoided to scrap, reduce waste of raw materials, reach saving at
Originally, the purpose for shortening the production cycle, improving efficiency.The utility model can be mating with common spanner, simple to operate, with biography
The removing method of system compares, and the utility model use is more convenient.
Detailed description of the invention
Fig. 1 is the utility model embodiment structural schematic diagram；
Fig. 2 is that the utility model uses schematic diagram.
In figure: the 1- body of rod, the clamping end 2-, 3- ratchet, 4- workpiece, the screw tap that 5- fractures, the gap 6-.
Specific embodiment
It is described further below with reference to preparation method of the embodiment to the utility model:
In the description of the present invention, it should be noted that unless otherwise clearly defined and limited, term " is pacified
Dress ", " connected ", " connection " shall be understood in a broad sense, for example, it may be being fixedly connected, may be a detachable connection, or integrally
Connection；It can be directly connected, it can also be indirectly connected through an intermediary.For the ordinary skill in the art,
The concrete meaning of above-mentioned term in the present invention can be understood with concrete condition.
See Fig. 1, be that the utility model universal type screw tap fractures and takes out device embodiment structural schematic diagram, structure is one section
The body of rod, one end of the body of rod 1 are clamping end 2, and the other end of the body of rod is ratchet 3, and the outer diameter of ratchet 3 is one in complete array of sizes
It is a, ratchet 3 along the body of rod 1 extending direction circumferentially to being uniformly distributed, the quantity of ratchet 3 is 3, and the shape of ratchet is cylindroid
Shape.The height of ratchet is 10mm.
Clamping end 2 be it is triangular prism shaped, geomery matches with corresponding ratchet spanner.
The high-intensitive tool steel rod elements that the body of rod 1 is 50 degree of Rockwell hardness or more.
Fig. 2 is seen, in use, the fracture clamping end 2 of the tool that takes out of the utility model universal type screw tap is installed to ratchet wrench
On hand, according to screw tap specification, which is 2,3,4 and differs, and in embodiment, ratchet quantity is selected according to screw tap specification
It selects, ratchet 3 is inserted into the gap 6 between the screw tap 5 to fracture and workpiece 4, rotates backward ratchet with the direction of rotation of tapping
Spanner slowly takes out the screw tap to fracture.It is easy to operate, machining period is saved, labor intensity is reduced.
Embodiment described above be only for be described in detail the purpose of this utility model, technical scheme and beneficial effects and choose
Specific example, but should in no way limit the protection scope of the utility model, it is all without prejudice to the spirit and principles of the utility model
Under the premise of, made various modifications, equivalent replacement and improvement should fall within the protection scope of this utility model.
