Also to be made by the internal thread spline that the inner wall of the swivel nut body 41 of swivel nut 40 is equipped with and the outer spiral spline constraint on 30 periphery of pull rod
Spiral rotating moves.Then, broaching tool 80 also follows pull rod 30 together while making axial linear movement and moved with spiral rotating, and stretches
Enter and carry out internal thread spline processing in workpiece to be machined to it, is i.e. the present invention can only on common horizontal broaching machine by broaching tool 80
Spiral rotating movement will also be made while making axial linear movement by changing into broaching tool 80 as axial linear movement, be realized general
Internal thread spline on logical horizontal broaching machine wire pulling method workpiece, so there is no need to as the processing multiple-internal screw thread on lathe
Carry out the manual actions such as indexing, feeding, tool sharpening and the detection of workpiece.Therefore, relatively low to processor's skill set requirements, processing
Compare easy, production efficiency is higher, and quality is more stable, labor intensity is smaller and size fluctuation is smaller.
As seen from Figure 3, the left end with broaching machine main shaft 100 of Left-wing Federation's female connector 20 are detachably connected using screw thread.This makes
Left-wing Federation's female connector 20 with the dismounting of broaching machine main shaft 100 and connect it is all more convenient easy.
By Fig. 3 and Fig. 4 as it can be seen that the invention also includes attaching nut 12, it is connected with straight up on each pressing plate 10
The stud 11 of stretching, each connecting lugs 52 are equipped with hole 53, and one end of each pressing plate 10 passes through attaching nut 12, stud
11 and hole 53 and connecting lugs 52 it is detachably connected.
Fig. 3 to Fig. 4 is as it can be seen that the invention also includes nut 22, and the left end of the pull rod 30 is equipped with screw thread, the pull rod 30
Left end stretches out and is fixed on except the left end of left bearing 23 and is located within Left-wing Federation's female connector 20 by screw thread and nut 22.This makes
Pull rod 30, which can more easily be located at, to be fixed on except the left end of left bearing 23 and is located within Left-wing Federation's female connector 20, as long as and
Nut 22 is removed from the screw thread on pull rod 30, it will be able to more easily by the left end of pull rod 30 out of Left-wing Federation's female connector 20 and
It is split out outward except the left end of bearing 23.
As seen from Figure 3, the left end of the right coupling sleeve 60 is equipped with the stud 62 stretched out to the left, accordingly, the pull rod 30
Right end be equipped with screw hole 31, the left end of the right coupling sleeve 60 by the right end of stud 62 and screw hole 31 and pull rod 30 removably
Connection.
By Fig. 3 and Fig. 5 as it can be seen that the broaching tool fixed structure 61,63；70；81 include the axial direction being located in right coupling sleeve 60
Pilot hole 61 is symmetrically arranged at two fixations of the inner wall and periphery of the right coupling sleeve of radial communication 60 of 61 upper and lower of axial pilot hole
Cotter way 63, two fixed cotter ways 81 of cooperation and two connecting pins 70 being correspondingly arranged on broaching tool 80, the left end of the broaching tool 80
By fixed cotter way 63, the fixed cotter way 81 of cooperation, the axial pilot hole being axially fixed at using connecting pin 70 in right coupling sleeve 60
In 61.This makes the dismounting of right coupling sleeve 60 and pull rod 30 and connection are all more convenient to be easy.
The swivel nut 40 is made of copper material.It can ensure in this way on internal thread spline and the pull rod 30 on its swivel nut body 41
Mutual abrasion is smaller when outer spiral spline is meshed, to improve the service life of swivel nut 40 and pull rod 30.
The swivel nut 40 is made of tin zinc-copper.It can ensure in this way on internal thread spline and the pull rod 30 on its swivel nut body 41
Outer spiral spline abrasion smaller mutual when being meshed, use the longevity to preferably improve swivel nut 40 and pull rod 30
Life.
As seen from Figure 3, the left bearing 23 is single row angular contact ball bearing.In the left end that can avoid pull rod 30 in this way
Side is in direct contact the service life that friction was worn, improved pull rod 30 and Left-wing Federation's female connector 20 with Left-wing Federation's female connector 20.
As seen from Figure 3, the right ball bearing 24 is double-direction thrust ball bearing.A left side for pull rod 30 can be preferably avoided in this way
End inside is in direct contact the service life that friction is worn, more improves pull rod 30 and Left-wing Federation's female connector 20 with Left-wing Federation's female connector 20.
The present invention use process is as follows；
First folder 50 will be drawn to be placed on broaching machine guide pass, draws the position of folder 50 well according to 80 Traffic control system of broaching tool, so
Afterwards, folder 50 will be drawn to be fixed on machine tool guideway 110 by pressing plate 10 and prevents from drawing the left and right movement during the work time of folder 50,
The left end of Left-wing Federation's female connector 20 is coupled tightly with the right end of machine tool chief axis 100 simultaneously, by the right end of positioning plate 90 and broaching machine front end
Workbench connects.Later, it will be put into and be pressed in positioning plate 90 by wire pulling method workpiece, checked and make swivel nut 40 and lathe master
Axis 100 and by wire pulling method workpiece whether coaxial inner conductor.Then, 80 left end of broaching tool is passed through by the endoporus of wire pulling method workpiece simultaneously
It is connect with 60 axial restraint of right coupling sleeve, starts broaching machine, it is multiple axially and in rotation that machine tool chief axis 100 drives pull rod 30 and broaching tool 80 to make
Resultant motion is completed to add workpiece internal thread spline after broaching tool 80 passes through completely from by the endoporus of wire pulling method workpiece
Work.
