Description
Technical field
The present invention relates to a kind of slender axles tapping tool of the tapping tool being applicable to small-diameter shaft part, particularly M4-M6.
Background technology
Difficult-to-machine material tapping is one technical barrier always, especially pincers worker is when carrying out tapping to the little axle of some difficult-to-machine materials (such as titanium alloy), screw tap very easily weares and teares, but for some enterprises, it is large that little axle throws Yield compari@, cycle is relatively short, therefore needs rational method to improve efficiency and the qualification rate of little axle tapping.
To the tapping of small-diameter shaft part, should ensure precision, save production cost again, shorten the production cycle, the method be the most simply suitable for is exactly the frock of utilitarian design, clamping is saved time, is convenient to again the processing of part.
General operation personnel adopt vice to block the two ends of axle, often process the screw thread of an axle, need twice clamping.Vice does not need to fix.Such operation, causes axle two ends easily to crush.And clamping is consuming time, efficiency is low.Clamping is improper, just cannot ensure the perpendicularity requirement of part.
The content of invention
Technology of the present invention is dealt with problems and is: provide one to be applicable to small-diameter shaft part tapping tool, and conveniently carry out holing and tapping on slender axles, clamping saves time, and is convenient to again the processing of part.
The small diameter shaft part tapping tool that is applicable to of the present invention comprises base and gland, described base is that the end face at the minor face place of cuboid has central through hole, and the upper surface at place, long limit is cut to the two stage steps cuboid of a part, described central through hole diameter is slightly larger than the diameter of axle of processed small diameter shaft part, respectively there is screwed hole in the upper surface of getting out of a predicament or an embarrassing situation being positioned at described central through hole both sides, through bottom through-hole is offered according to the direction perpendicular to described central through hole at the bottom surface place being positioned at the central through hole of getting out of a predicament or an embarrassing situation, described gland is the cuboid plate that described base can be coordinated to be cut part, in the correspondence of described gland, described bottom through-hole place offers through hole, described through-hole diameter depends on the diameter in merit silk hole, the diameter of described bottom through-hole is more than or equal to the diameter of described through hole, tapped through hole is offered at the screwed hole place of the corresponding respectively described base of described gland, described base and described gland can utilize described screwed hole and tapped through hole to carry out compression with lock-screw to be connected.
The diameter of the through hole of preferred described gland is φ 7mm, and the diameter of the bottom through-hole of described base is more than or equal to φ 7mm, as chip removal mouth.
Preferred described central through hole diameter 2-5 millimeter larger than the diameter of axle of processed small diameter shaft part.
Preferred described screwed hole has two, configures according to clinodiagonal mode.
The present invention compared with prior art tool has the following advantages:
(1) base has be more than or equal to φ 7mm through hole, crossing with the through hole of clamping parts, position is relative with the φ 7mm through hole on gland, and during use, the iron filings that tapping produces can directly be discharged from φ 7mm hole base, can not produce to squeeze and consider to be worth doing.
(2) need not clamping small-diameter shaft part energetically, therefore can not cause crushing of part.
(3) can as reaming frock behind small-diameter shaft part location.
(4) simple to operate, efficiency is high.
(5) boring of axial workpiece cylindrical or the tapping of multiple diameter is applicable to.
Accompanying drawing explanation
Fig. 1 is frock sectional arrangement drawing of the present invention;
Fig. 2 is frock assembly relation left view of the present invention;
Fig. 3 is frock assembly relation top view of the present invention;
Detailed description of the invention
As shown in Figure 1, Figure 2 and Figure 3, the small diameter shaft part tapping tool that is applicable to of the present invention uses when reaming or thread mill drilling on little axle cylindrical, base 1 and gland 2 is formed by connecting by lock-screw 3.Base 1 processes a through central through hole by the end face at the minor face place at a cuboid, and then up body upper surface cut a part, and make the cuboid of a two stage steps, the diameter of axle of the small diameter shaft part that this central through hole diameter is processed as required and determining, goes out greatly 2-5 millimeter than this diameter of axle usually.Two are processed with for installing the screwed hole of locking nut 3 according to clinodiagonal mode in the upper surface of getting out of a predicament or an embarrassing situation being positioned at described central through hole both sides, bottom through-hole is offered according to the direction perpendicular to above-mentioned central through hole at the bottom surface place being positioned at the central through hole of getting out of a predicament or an embarrassing situation, this bottom through-hole obtains diameter and is more than or equal to φ 7mm, can be used as chip removal mouth, the crowded bits that process produces can be discharged from chip removal mouth, and the central through hole on base can be matched according to the diameter of axial workpiece to be processed.
Gland 2 is the cuboid plates being cut part that can coordinate base 1, namely gland 2 can cover on the getting out of a predicament or an embarrassing situation of base 1, the through hole of φ 7mm is offered at the above-mentioned bottom through-hole place of the correspondence of gland 2, this through-hole diameter can change according to the diameter of tapping hole, offer tapped through hole at the screwed hole place of the corresponding respectively base 1 of gland 2, utilize lock-screw 3 can carry out compression to base 1 with gland 2 and be connected.
When on the axle cylindrical at diameter being 6mm boring and tapping time:
(1) part that will process (the little axle of M6) is put into the central through hole interior (this central through hole diameter elects φ 10mm as) of little axle tapping tool base 1, with gland 2 fixed axis part, be pressed on base 1 by 2 lock-screws 3, make it can not offset in process.
(2) frock is levelling, be fixed on lathe table top with vice.
(3) with the center, φ 7mm hole of the drill bit centering gland 2 of tapping machine.
(4) start tapping machine, drill bit is passed in φ 7mm hole from gland, part is holed.
(5) after boring terminates, remove drill bit, screw tap is installed.
(6) start tapping machine, screw tap is passed in φ 7mm hole from gland, tapping is carried out to part.
(7) after tapping, take off gland 2, part is taken out.
Above the preferred embodiment of the present invention is illustrated, but the present invention is not limited to above-described embodiment.To one skilled in the art, in the category described in claims, various modification or fixed case can be expected apparently, certainly also belong to technology category of the present invention.
