Description
Technical field
The utility model relates to a kind of hardware & tools, and a kind of engine duct special screw tap, belongs to Machining Technology field specifically.
Background technology
Screw tap is the common hardware & tools of a kind of field of machining, is mainly used in machining internal thread on workpiece, also claims tap.Regular tap, by fixing square toes, tap holder and screw tap operate portions, makes a circle outside described screw tap operate portions and is provided with screw tap blade uniformly, during use, just carries out tapping with screw tap blade to workpiece.And due to current screw tap blade be all the form such as spirality or single thread, and the engine duct inner hole thread that my company now will process is double end right-handed thread, and double thread is deep mixed, so the regular tap on existing market cannot meet processing needs, and existing screw tap blade front pilot Design of length is improper, some is too short easily holds moment of torsion that can't stand increasing and fractures, and service life is short, and some long not only waste of material and guide effect is bad.
Utility model content
For the problems referred to above, the problem that the utility model quasi-solution is determined be to provide a kind of rational in infrastructure, lead, long service life and the engine duct special screw tap of good stability.
For achieving the above object, the utility model is by the following technical solutions: a kind of engine duct special screw tap, comprise integrated screw tap operate portions, tap holder and fixing square toes, described fixing square toes are arranged on one end of described tap holder, described screw tap operate portions is arranged on the other end of described tap holder, described screw tap operate portions, the axis of described tap holder and described fixing square toes on the same line, make a circle outside described screw tap operate portions and be provided with three groups of screw tap blades uniformly, a chip area is provided with between every two adjacent groups screw tap blade, often organize described screw tap blade and be double end right-handed thread, and the degree of depth of double thread is not etc., described screw tap blade front pilot length is set to 5 ± 0.5mm.
As preferably, described screw tap blade front pilot length is set to 5mm.
Effective achievement of the present utility model: the utility model is rational in infrastructure, make a circle outside screw tap operate portions and be provided with three groups of screw tap blades uniformly, and screw tap blade is set to double end right-handed thread, not only resistance to overturning is good, and solves the processing problems of double end right-handed thread groove on company's engine duct endoporus hole wall; Again screw tap blade front pilot length is set to 5 ± 0.5mm, not only good the and long service life of guide effect.In sum, the utility model have rational in infrastructure, lead, long service life and the feature of good stability.
Accompanying drawing explanation
Fig. 1 is front view of the present utility model.
Fig. 2 is right view of the present utility model.
Fig. 3 is the part sectioned view of one group of screw tap blade in Fig. 1.
In figure: 1-screw tap operate portions, 2-tap holder, 3-fixes square toes, 4-screw tap blade, 5-chip area.
Detailed description of the invention
In order to make those skilled in the art person better understand the utility model scheme, below in conjunction with the accompanying drawing in the present embodiment, clear, complete description is carried out to the technical scheme in the utility model embodiment.
As Fig. 1, shown in Fig. 2 and Fig. 3, the utility model discloses a kind of engine duct special screw tap, comprise integrated screw tap operate portions 1, tap holder 2 and fixing square toes 3, fixing square toes 3 are arranged on one end of tap holder 2, screw tap operate portions 1 is arranged on the other end of tap holder 2, screw tap operate portions 1, the axis of tap holder 2 and fixing square toes 3 on the same line, make a circle outside screw tap operate portions 1 and be provided with three groups of screw tap blades 4 uniformly, a chip area 5 is provided with between every two adjacent groups screw tap blade 4, often organize screw tap blade 4 and be double end right-handed thread, and the degree of depth of double thread is not etc., screw tap blade 4 front pilot length is set to 5 ± 0.5mm.
The utility model is rational in infrastructure, make a circle outside screw tap operate portions 1 and be provided with three groups of screw tap blades 4 uniformly, and screw tap blade 4 is set to double end right-handed thread, not only resistance to overturning is good, and solves the processing problems of double end right-handed thread groove on company's engine duct endoporus hole wall; Again screw tap blade 4 front pilot length is set to 5 ± 0.5mm, not only good the and long service life of guide effect.In sum, the utility model have rational in infrastructure, lead, long service life and the feature of good stability.
Obviously, described embodiment is only a part of embodiment of the present utility model, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all should belong to the scope of the utility model protection.
