Manufacturing technology field.
Background technology
Regular screw threads hole devises chamfering at screw initial thread, causes on its first thread to assemble bolt conveniently
Side is without helical angle, and from screw thread starting point until the second tooth slowly becomes complete, therefore the first tooth is incomplete thread, such as Fig. 1 institutes
Show.
It is well known that threaded engagement effect maximum is all the first eight pitch thread stress, and the first pitch thread stress is maximum, reaches
To 30% or so, because of the first tooth imperfection of conventional threads, the first pitch thread is caused to be easy to damage in stress.
The content of the invention
For above-mentioned shortcoming of the prior art, the present invention is intended to provide a kind of brand-new thread pore structure and processing
The screw thread reamer gang tool of the thread pore structure, it machines away incomplete thread part, forms the spiral shell with full thread
Line structure, calculates through analysis, which may be such that the power that the first thread of screw thread bears to draw or presses is greatly improved, at least
Lifting more than 25%, and is hardly damaged, while the diameter for machining away position becomes larger, when equally can be bolts assemblies from be oriented to work
With.
To achieve these goals, technical scheme：A kind of thread pore structure, it includes threaded hole body, should
Threaded hole body has some threads, it is characterised in that：The outermost thread of the threaded hole body is complete thread.
Further, the threaded hole body port inner circumferential has interior step, the interior step and the outermost spiral shell
Tooth is adjacent, and the interior diameter of the interior step is more than or equal to the major diameter diameter of the thread.
Further, the threaded hole body port position has step in technique.
A kind of screw thread reamer gang tool for processing aforementioned threads pore structure, it includes integrally formed reamer cutter sheet
Body, it is characterised in that：The reamer cutter body includes cutter part and its handle portion of tail end, and the cutter part is by the hand
Shank includes forward reamer section, screw tap section, guide section successively, wherein, the major diameter diameter of the reamer section is more than or equal to described
The major diameter diameter of screw tap section, and by Bottom of Thread transition between the reamer section and the screw tap section, and the Bottom of Thread and institute
The Bottom of Thread for stating screw tap section is identical.
Further, the reamer section cutting edge has helical angle, and the helical angle is equal with the helical angle of the screw tap section.
Further, the reamer cutter body peripheral in axial direction has several bit-withdrawing slots, and the bit-withdrawing slot is by described
Guide section free end extends to the handle portion, and the length of the bit-withdrawing slot is more than the length of the cutter part.
Beneficial effects of the present invention：Incomplete thread part is machined away, forms the helicitic texture with full thread, warp
Analysis calculates, which may be such that the power that the first thread of screw thread bears to draw or press is greatly improved, and at least lifts 25%
More than, and be hardly damaged, while the diameter for machining away position becomes larger, and play the guiding role when equally can be bolts assemblies.
Brief description of the drawings
Fig. 1 is the machining sketch chart of conventional thread formation；
Fig. 2 is the structure diagram of helicitic texture of the present invention；
Fig. 3 is the front view of screw thread reamer gang tool in the present invention；
Fig. 4 is the sectional view of Fig. 3.
Embodiment
The present invention is further described with reference to specific embodiment and attached drawing.
A kind of thread pore structure as described in Figure 2, it includes threaded hole body 10, which has some threads
11, the outermost thread 12 of the threaded hole body 10 is complete thread.
Wherein, 10 port inner circumferential of threaded hole body has interior step 13, the interior step 13 and 12 phase of outermost thread
Neighbour, and the interior diameter of the interior step 13 is more than or equal to the major diameter diameter of thread 11.By removing outermost in threaded hole body 10
Imperfect thread part, you can so that whole helicitic texture bears drawing or the pressure of bigger, especially the threaded hole body 10 most
The drawing of outside thread or pressure, its power that can bear to draw or press are greatly improved, and are analyzed by calculating, can at least lift 25%
More than, screw thread is less damaged.And the incomplete thread part being processed forms interior step 13, when can be bolts assemblies
It play the guiding role.
Finally, there is step 14 in technique in 10 port position of threaded hole body, during for processing screw thread from be oriented to and fixed
Use position.
As shown in Figure 3,4, the invention also discloses it is a kind of process aforementioned threads pore structure screw thread reamer gang tool, its
Include integrally formed reamer cutter body 1, which includes cutter part and its handle portion 24 of tail end,
Cutter part is included forward reamer section 22, screw tap section 21, guide section 20 by handle portion 24 successively, wherein, the major diameter of reamer section 22
Diameter is more than or equal to the major diameter diameter of screw tap section 21, and by Bottom of Thread transition between the reamer section 22 and screw tap section 21, and
The Bottom of Thread is identical with the Bottom of Thread of screw tap section 21.
Specifically, 1 periphery of reamer cutter body in axial direction has several bit-withdrawing slots 23, and the bit-withdrawing slot 23 is by guide section
