Lacked 25% or more promotion, and be hardly damaged, while the diameter for machining away position becomes larger, when equally can be bolts assemblies from be oriented to
Effect.
To achieve the goals above, the technical solution of the utility model：A kind of thread pore structure comprising threaded hole sheet
Body, the threaded hole ontology have several threads, it is characterised in that：The outermost thread of the threaded hole ontology is complete thread.
Further, threaded hole ontology 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 ontology port position has step in technique.
A kind of screw thread reamer gang tool of processing aforementioned threads pore structure comprising have 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 reamer section, screw tap section, guide section successively forward, 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, the helical angle equal with the helical angle of 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.
The beneficial effects of the utility model：Incomplete thread part is machined away, the screw thread knot with full thread is formed
Structure is calculated through analysis, which may make the power that the first thread of screw thread bears to draw or press to be greatly improved, and is at least promoted
25% or more, and be hardly damaged, while the diameter for machining away position becomes larger, and play the guiding role when equally can be bolts assemblies.
Description of the drawings
