Abstract
The utility model provides a lead-in tapping device, including a tap collet, a lead screw and a lead nut, which are tube-likely connected through screw thread from inner to outer in turn; the top of said tap collet has a groove with a perforative hole from top to bottom, characterized in that a bearing and a pipeline which connects the oil tank are included; the inner wall of said lead screw is equipped with several grooves on; said bearing is wedged in the groove of the top of said tap collet, whose axle hole is connected with the centre through hole of said tap collet; said pipeline can be plugged into or drawn out of said bearing axle hole. When plugged into said bearing axle hole, the pipeline can lead liquid into the centre through hole of the tap collet. The liquid flows out through the grooves of said lead screw, bestrewing on the surface of said tap collet.
Description
Technical field
The utility model relates to a kind of screw processing equipment, is specifically related to a kind of interior tapping helical pitch device of mould that is provided with inner pipeline road.
Background technology
The helical pitch device of tapping machinery in the mould of the prior art generally all is to adopt the outside cooling and lubricating device that installs additional, by being arranged on the side feed lubricating oil of outside pipeline road to the screw tap working position, to realize the cooling to tapping tapping position.This device exists the shortcoming of three aspects: the one, because pipeline road is external, need occupy certain space, and the client is installed and used and mould design empty avoiding position etc., obviously bring inconvenience; The 2nd because this external pipeline road do not have the fuel delivery governor motion, during mold work appearance often also stream expired lubricating oil, pollute easily; Since the external pipeline road be a side from screw tap to the working position fuel feeding, thereby the fuel feeding effect at the screw tap back side is bad, cooling effect is bad, and causes the waste of lubricating oil.
The utility model content
At existing above-mentioned shortcoming in the prior art, the purpose of this utility model is, tapping helical pitch device in a kind of mould is provided, this device is provided with one and is used for from the pipeline road of screw tap inside to the working position fuel feeding, make lubricating oil evenly flow to the working position, need not to be provided with again external pipeline road from top, working position.
The utility model realizes that the technical scheme that above-mentioned purpose adopted is:
Tapping helical pitch device in a kind of mould, it includes tubulose, sheathed successively, and the tap chuck, a helical pitch screw rod and the helical pitch nut that are threaded successively from inside to outside; Described tap chuck top is provided with a groove, and the center is provided with a through hole that runs through up and down, it is characterized in that, it comprises that also a bearing, connects the petroleum pipeline of fuel tank; Described helical pitch screw rod inwall is provided with some grooves; Described bearing is fastened in the set groove in described tap chuck top, and its axis hole and described tap chuck central through hole are interconnected; Described petroleum pipeline can insert from described bearing axis hole or extract, when it inserts in the described bearing axis hole, liquid can be imported described tap chuck central through hole, this liquid flows out through described helical pitch screw flutes again, is distributed on the surface of described tap chuck.
Tapping helical pitch device in the aforesaid mould is characterized in that, on the described petroleum pipeline, also is provided with a fuel-flow control switch.
Tapping helical pitch device in the aforesaid mould is characterized in that described liquid is lubricating oil.
Tapping helical pitch device in the aforesaid mould is characterized in that described helical pitch screw rod, helical pitch nut and bearing all are stainless steel or copper member.
During the utility model work, rotatablely move up and down by the helical pitch screw rod that matches with the helical pitch nut, drive the tap chuck tapping moulding that moves up and down, its cooling liquid, then enter the central through hole of tap chuck from the axis hole of bearing by built-in petroleum pipeline as lubricating oil, flow out behind the inboard wall groove through the helical pitch screw rod again, be distributed on the surface of described screw tap, in order to cooling, lubricated tapping screw tap and tapping workpiece bottom outlet.
Advantage of the present utility model is: because this utility model has adopted built-in pipeline road, can make lubricating oil from top to bottom to the working face fuel feeding, and make on its surface that is distributed on tap chuck, its cooling, lubricant effect are stable, reliable, can improve the crudy of screw tap service life and workpiece, and reduce the waste of lubricating oil; Owing to need not to be provided with external pipeline road, saved space outerpace, simplify frame for movement, and be convenient to mechanically actuated and mould design, easy to use; Owing to be provided with the attaching parts of bearing as petroleum pipeline, can keep petroleum pipeline not produce to the reverse rotation of helical pitch screw rod by bearing self and reverse, and petroleum pipeline can directly insert or extract the axis hole of bearing, install and use very convenient.

The specific embodiment
Embodiment referring to Fig. 1～Fig. 4, provides tapping helical pitch device in a kind of mould, and it includes tubulose, sheathed successively, and the tap chuck 3, a helical pitch screw rod 1 and the helical pitch nut 2 that are threaded successively from inside to outside; Described tap chuck 3 tops are provided with a groove 31, and the center is provided with a through hole that runs through up and down 32, and it comprises that also a bearing 4, connects the petroleum pipeline 5 of fuel tank; Described helical pitch screw rod 1 inwall is provided with four axial notches 11; Described bearing 4 is fastened in the set groove 31 in described tap chuck 3 tops, and its axis hole and described tap chuck central through hole 32 are interconnected; Described petroleum pipeline 5 can insert from described bearing 4 axis holes or extract, when it inserts in described bearing 4 axis holes, liquid can be imported described tap chuck central through hole 32, this liquid flows out through described helical pitch screw flutes 11 again, is distributed on the surface of described tap chuck 3.
On the described petroleum pipeline 5, also be provided with a fuel-flow control switch.
Described liquid is lubricating oil.
Described helical pitch screw rod 1, helical pitch nut 2 and bearing 4 all are stainless steel or copper member.
Tapping helical pitch device in the structure identical or approximate as the utility model the foregoing description, resulting mould is all within the utility model protection domain.
