Abstract
The utility model discloses a kind of adjustable threading tools of lead angle, the adjustable cutter head including being equipped with blade, are provided with circular arc waist-shaped hole on the adjustable cutter head；Further include knife handle, threaded fastening hole is provided in the knife handle distal end faces, the circular arc waist-shaped hole is corresponding with threaded fastening hole；The knife handle is detachably fastenedly connected with the adjustable cutter head by least one bolt in circular arc waist-shaped hole；By adjusting the relative angle between cutter head and knife handle come realize different lead angles screw chasing processing；It is a large amount of to save tool cost without replacing the lathe tool of specific model.
Description
Technical field
The utility model belongs to machine tool field more particularly to a kind of adjustable threading tool of lead angle.
Background technique
The formation of screw thread needs a compound motion, and the helicoid of screw thread is the screw thread in the axial section by the screw thread
Face type section shape line (bus), axially helix (conducting wire) movement and formed.No matter any screw thread of turning, it is necessary to
Bus (flank type) and conducting wire (helix) are formed in processing.When with threading tool cutted thread, formed bus (forming process)
Forming moving is not needed.Projection line of the cutting edge of threading tool in the pitch diameter of thread axial section where point of a knife, is exactly this
The bus of screw thread moves as long as threading tool does track along axial screw spin line, so that it may which turning goes out the helicoid of screw thread.
At present in thread turning process, for the screw thread of special requirement, need to be equipped with special one threading tool.
The process for ordering special screw thread lathe tool, can undoubtedly elongate the production and processing period of screw product.If the market of this screw product
Demand is simultaneously little, and processing quantity is relatively fewer, then being equipped with one exclusively for it lathe tool, virtually also increases machining enterprise
Production cost.
In view of above-mentioned defect, the designer is actively subject to research and innovation, to found a kind of new structural screw thread liter
The adjustable threading tool in angle makes it with more the utility value in industry.
Summary of the invention
Goal of the invention: in order to overcome the deficiencies in the prior art, it is adjustable that the utility model provides a kind of lead angle
Threading tool.
Technical solution: to achieve the above object, a kind of adjustable threading tool of lead angle of the utility model, including peace
Adjustable cutter head equipped with blade is provided with circular arc waist-shaped hole on the adjustable cutter head；It further include knife handle, the knife handle end
Threaded fastening hole is provided on end face, the circular arc waist-shaped hole is corresponding with threaded fastening hole；The knife handle is adjusted with described
Cutter head is detachably fastenedly connected by least one bolt in circular arc waist-shaped hole；
The several first radial straight-tooth slots, the faying face of the adjustable cutter head are provided on the end face of the knife handle end
On be provided with the several second radial straight-tooth slots；The first radial straight-tooth slot and the second radial straight-tooth slot are mutually nibbled
It closes.
Further, the radiation origin of the described first radial straight-tooth slot and the second radial straight-tooth slot and the circle
The circular arc center of circle of arc waist-shaped hole is overlapped.
Further, the blade is the quasi- threaded lathe tool blade of 60 scales, and the bolt is hexagon socket head cap screw, the knife handle
For hard alloy steel square body；The blade detachably fastens installation by pin for suppressing metal and the adjustable cutter head.
Further, the circular arc waist-shaped hole is countersunk head circular arc waist-shaped hole.
The utility model has the advantages that the utility model at least has the following advantages:
The utility model threading tool is to realize different screw thread liters by adjusting the relative angle between cutter head and knife handle
The screw chasing processing at angle；It is a large amount of to save tool cost without replacing the lathe tool of specific model；
Lead angle is lead angle, is exactly the tangent line of helix and the plane perpendicular to the axis of thread on central diameter cylinder
Between angle.In thread turning process, in order to form the helix of certain lead, it is necessary to assure main shaft each rotation,
Cutter accurately moves the distance of processed one lead of screw thread.The adjustable threading tool of the utility model lead angle, works as knife
When head rotates by a certain angle relative to knife handle, projection line of the cutting edge of blade in the pitch diameter of thread axial section where point of a knife
Angle between the plane perpendicular to the axis of thread will change correspondingly certain angle.No matter which kind of lead angle is processed
Screw product, it is only necessary to which one the adjustable threading tool of lead angle.In process, for different lead angles, lead to
The angle adjusted between the cutter head of this threading tool and knife handle is crossed, the processing of nonstandard screw thread can be realized.
Solves the screw product for being directed to special thread lift angle at present, it is necessary to be equipped with the various disadvantages of dedicated threading tool
End is greatly saved the process for ordering cutter, shortens the process-cycle, while also saving processing cost.
Detailed description of the invention
Attached drawing 1 is the utility model overall structure diagram；
Partial schematic diagram under state that attached drawing 2 is adjustable cutter head and knife handle junction is staggered；
Attached drawing 3 is about the relation principle figure during thread turning between lead angle, the pitch diameter of thread and lead.
Specific embodiment
The utility model is further described with reference to the accompanying drawing.
A kind of adjustable threading tool of lead angle as shown in attached drawing 1 to 3, the adjustable knife including being equipped with blade 1
First 3, circular arc waist-shaped hole 7 is provided on the adjustable cutter head 3；Further include knife handle 6, is provided in 6 distal end faces of knife handle
Threaded fastening hole, the circular arc waist-shaped hole 7 are corresponding with threaded fastening hole；The knife handle 6 passes through circle with the adjustable cutter head 3
At least one bolt 2 in arc waist-shaped hole 7 is detachably fastenedly connected；It is realized using the structure of circular arc waist-shaped hole 7 and adjusts cutter head 3
With the connection and fastening of the different angle within the scope of certain angle of knife handle 6.
The several first radial straight-tooth slots 5, the knot of the adjustable cutter head 3 are provided on the end face of 6 end of knife handle
The several second radial straight-tooth slots 4 are provided on conjunction face；The first radial straight-tooth slot 5 and the second radial straight-tooth slot
