Abstract
The utility model discloses a kind of screw thread reamer gang tools, include integrally formed reamer cutter body, it is characterised in that：The reamer cutter body includes cutter part and its handle portion of tail end, the cutter part is included forward reamer section, screw tap section, guide section by the handle portion successively, wherein, the major diameter diameter of the reamer section is more than or equal to the major diameter diameter of the screw tap section, and by Bottom of Thread transition between the reamer section and the screw tap section, and the Bottom of Thread is identical with the Bottom of Thread of the screw tap section.The utility model can machine away thread belt chamfered part, realization threaded portion is perfect thread, and then can realize the depth of thread of constant depth for processing screw thread.
Description
Technical field
The utility model is related to a kind of screw thread reamer gang tools, belong to cutting-tool engineering field.
Background technology
Regular screw threads cutter is before tapping, it is necessary to and a chamfering is processed at the screw thread place of eating dishes without rice or wine, plays guiding function, and due to this
The presence of chamfering is no helical angle on the upside of the first tooth of screw thread, is incomplete thread.In consideration of it, the utility model exists
A gang tool for processing full thread is devised on this basis.
The content of the invention
Shortcoming in for the above-mentioned prior art, the utility model are intended to provide a kind of screw thread reamer gang tool,
For processing screw thread, thread belt chamfered part can be machined away, realization threaded portion is perfect thread, and then can be realized fixed deep
The depth of thread of degree.
To achieve these goals, the technical solution of the utility model：A kind of screw thread reamer gang tool, includes one
Body formed reamer cutter body, it is characterised in that：The reamer cutter body includes cutter part and its handle portion of tail end,
The cutter part is included forward reamer section, screw tap section, guide section by the handle portion successively, wherein, the reamer section it is big
Footpath diameter is more than or equal to the major diameter diameter of the screw tap section, and passes through Bottom of Thread mistake between the reamer section and the screw tap section
It crosses, and the Bottom of Thread is identical with the Bottom of Thread 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.
Further, it is in multidiameter structure between the cutter part and the handle portion.
Further, the reamer section cutting edge has helical angle, and the helical angle is equal with the helical angle of the screw tap section.
The beneficial effects of the utility model：For processing screw thread, thread belt chamfered part can be machined away, realize threaded portion
It is divided into perfect thread, and then can realizes the depth of thread of constant depth, while machines away part by reamer to realize bolt
Pre- band.
Description of the drawings
Fig. 1 is the structure chart of the utility model；
Fig. 2 is the sectional view of Fig. 1.
Specific embodiment
The utility model is further described with reference to specific embodiment and attached drawing.
A kind of screw thread reamer gang tool described as shown in Figure 1, Figure 2, includes integrally formed reamer cutter body 1, should
Reamer cutter body 1 includes cutter part and its handle portion 14 of tail end, and cutter part is included forward hinged successively by handle portion 14
Knife section 12, screw tap section 11, guide section 10, wherein, the major diameter diameter of reamer section 12 is more than or equal to the major diameter diameter of screw tap section 11, and
By Bottom of Thread transition between the reamer section 12 and screw tap section 11, and the Bottom of Thread phase of the Bottom of Thread and screw tap section 11
Together.
Specifically, 1 periphery of reamer cutter body in axial direction has several bit-withdrawing slots 13, and the bit-withdrawing slot 13 is by guide section
10 free ends extend to handle portion 14, and the length of the bit-withdrawing slot 13 is more than the length of cutter part.And 12 cutting edge of reamer section has
Helical angle, the helical angle are equal with the helical angle of screw tap section 11.In addition, it is in multidiameter structure between cutter part and handle portion 14.
By this gang tool machining internal thread, the imperfect thread removal of the first tooth of screw thread port position may be such that
Fall, so that entire internal thread is full thread.
The technical solution provided above the utility model embodiment is described in detail, used herein specifically
A example is set forth the principle and embodiment of the utility model embodiment, and the explanation of above example is only applicable to help
Assistant solves the principle of the utility model embodiment；Meanwhile for those of ordinary skill in the art, implement according to the utility model
Example, the there will be changes in specific embodiment and application range, in conclusion this specification content should not be construed as
Limitation to the utility model.
