Description
Technical field
The utility model relates to a kind of slender axles tapping tool of the tapping tool that is 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 in the time 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, little axle operation amount is larger, cycle is relatively short, therefore needs to have 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 most applicable method is exactly the practical frock of design, and clamping is saved time, and is convenient to again the processing of part.
The two ends that general operation personnel adopt vice to block axle, the screw thread of an axle of every processing, needs twice clamping. Vice does not need to fix. Operation, causes axle two ends easily to crush like this. 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 utility model is dealt with problems and is: provide one to be applicable to small-diameter shaft part tapping tool, and convenient boring on slender axles and tapping, 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 utility model comprises base and gland, described base is that the end face at the minor face place of cuboid has central through hole, and the two stage steps cuboid that the upper surface cutting part at place, long limit is formed, described central through hole slightly larger in diameter is in the diameter of axle of processed small diameter shaft part, there is respectively screwed hole in the upper surface of getting out of a predicament or an embarrassing situation that is positioned at described central through hole both sides, at the bottom surface place that is positioned at the central through hole of getting out of a predicament or an embarrassing situation according to the bottom through-hole that offers perforation perpendicular to the direction of described central through hole, described gland is to coordinate described base to be cut the cuboid plate of part, the described bottom through-hole of correspondence place at described gland 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, screwed hole place at the corresponding described base respectively of described gland offers tapped through hole, described base can utilize described screwed hole and tapped through hole to compress and be connected with lock-screw with described gland.
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 is than the large 2-5 millimeter of the diameter of axle of processed small diameter shaft part.
Preferred described screwed hole has two, configures according to clinodiagonal mode.
The utility model compared with prior art tool has the following advantages:
(1) on base, have and 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, when use, the iron filings that tapping produces can be directly from base φ 7mm hole discharge, can not produce and squeeze bits.
(2) clamping small-diameter shaft part energetically, therefore can not cause crushing of part.
(3) can be used as reaming frock behind small-diameter shaft part location.
(4) simple to operate, efficiency is high.
(5) the axial workpiece cylindrical that is applicable to multiple diameter is holed or tapping.

Fig. 2 is frock assembly relation left view of the present utility model;
Fig. 3 is frock assembly relation top view of the present utility model;
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 utility model uses when reaming or thread mill drilling on little axle cylindrical, by lock-screw 3, base 1 and gland 2 is formed by connecting. Base 1 is by the central through hole of a perforation of end face processing at the minor face place at a cuboid, and then a part is cut in the upper surface of body up, 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 conventionally. Be processed with two for the screwed hole of locking nut 3 is installed in the upper surface of getting out of a predicament or an embarrassing situation that is positioned at described central through hole both sides according to clinodiagonal mode, offer bottom through-hole at the bottom surface place that is positioned at the central through hole of getting out of a predicament or an embarrassing situation according to the direction perpendicular to above-mentioned central through hole, 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 that are cut part that can coordinate base 1, be that gland 2 can cover on the getting out of a predicament or an embarrassing situation of base 1, offer the through hole of φ 7mm at the above-mentioned bottom through-hole of the correspondence place of gland 2, this through-hole diameter can change according to the diameter of tapping hole, screwed hole place at the corresponding base 1 respectively of gland 2 offers tapped through hole, utilizes lock-screw 3 can base 1 be compressed and is connected with gland 2.
In the time of boring on the axle cylindrical that is 6mm at diameter tapping:
(1) part that will process (the little axle of M6) is put in the central through hole of little axle tapping tool base 1 (this central through hole diameter is elected φ 10mm as), with gland 2 fixed axis parts, be pressed on base 1 by 2 lock-screws 3, it can not be offset in process.
(2), by frock levelling, be fixed on lathe table top with vice.
(3) the φ7mmKong center of the drill bit centering gland 2 of use tapping machine.
(4) starting tapping machine passes drill bit from gland in φ 7mm hole, and part is holed.
(5) after boring finishes, remove drill bit, screw tap is installed.
(6) starting tapping machine passes screw tap from gland in φ 7mm hole, and part is carried out to tapping.
(7) after tapping, take off gland 2, part is taken out.
Above preferred embodiment of the present utility model is illustrated, but the utility model is not limited to above-described embodiment. To one skilled in the art, in the category of recording at claims, can expect apparently various modifications or fixed case, certainly also belong to technology category of the present utility model.
