Enter it is carried out internal thread spline processing, the i.e. present invention in workpiece to be machined can only on common horizontal broaching machine by broaching tool 80
Broaching tool 80 spiral rotating to be made motion while making axial linear movement is changed into, it is achieved that general as axial linear movement
Internal thread spline on logical horizontal broaching machine wire pulling method workpiece, so there is no need to as processing multiple-internal screw thread on lathe
Carry out the manual action such as the indexing of workpiece, feeding, tool sharpening and detection.Therefore, processing relatively low to processor's skill set requirements
The easiest, production efficiency is higher, and quality is more stable, labor intensity is less and size fluctuation is less.
As seen from Figure 3, the left end of described Left-wing Federation female connector 10 uses screw thread detachably connected with broaching machine main shaft 100.This makes
Left-wing Federation's female connector 10 with the dismounting of broaching machine main shaft 100 and be connected the most more convenient easily.
From Fig. 3 and Fig. 4, present invention additionally comprises attaching nut 12, described each pressing plate 10 connects to be had straight up
The stud 11 stretched out, described each connection journal stirrup 52 is provided with hole 53, and attaching nut 12, stud are passed through in one end of each pressing plate 10
11 and hole 53 with to be connected journal stirrup 52 detachably connected.
Fig. 3 to Fig. 4 is visible, present invention additionally comprises nut 22, and the left end of described pull bar 30 is provided with screw thread, described pull bar 30
Left end stretches out and passes through screw thread and nut 22 be fixed on the left end of left bearing 23 outside and within being positioned at Left-wing Federation's female connector 20.This makes
Outside pull bar 30 can be positioned at the left end being fixed on left bearing 23 more easily and within being positioned at Left-wing Federation's female connector 20, as long as and
To take off on the nut 22 screw thread from pull bar 30, it becomes possible to more easily by the left end of pull bar 30 in Left-wing Federation's female connector 20 and
Outwards split out outside the left end of bearing 23.
As seen from Figure 3, the left end of described right coupling sleeve 60 is provided with the stud 62 stretched out to the left, accordingly, described pull bar 30
Right-hand member be provided with screw 31, the left end of described right coupling sleeve 60 is by the right-hand member of stud 62 and screw 31 and pull bar 30 removably
Connect.
From Fig. 3 and Fig. 5, described broaching tool fixed structure 61,63；70；81 include being located in right coupling sleeve 60 axial
Pilot hole 61, the inwall of the right coupling sleeve of radial communication 60 being symmetrically arranged at axial pilot hole 61 upper and lower is fixed with two of periphery
Cotter way 63, two be correspondingly arranged on broaching tool 80 coordinate fixing cotter way 81 and two connecting pins 70, the left end of described broaching tool 80
By fixing cotter way 63, coordinate fixing cotter way 81, use connecting pin 70 to be axially fixed at the axial pilot hole in right coupling sleeve 60
In 61.This make right coupling sleeve 60 and the dismounting of pull bar 30 and be connected the most more convenient easily.
Described swivel nut 40 is made up of copper material.So ensure that on the internal thread spline on its swivel nut body 41 and pull bar 30
When outer spiral spline is meshed, abrasion each other is less, thus improves swivel nut 40 and the service life of pull bar 30.
Described swivel nut 40 is made up of stannum zinc-copper.So ensure that on the internal thread spline on its swivel nut body 41 and pull bar 30
Outer spiral spline when being meshed abrasion each other less, thus preferably improve swivel nut 40 and the use longevity of pull bar 30
Life.
As seen from Figure 3, described left bearing 23 is single row angular contact ball bearing.So it can be avoided that in the left end of pull bar 30
Side directly contacts friction with Left-wing Federation female connector 20 and is worn, improves pull bar 30 and the service life of Left-wing Federation's female connector 20.
As seen from Figure 3, described right ball bearing 24 is double-direction thrust ball bearing.So can preferably avoid a left side for pull bar 30
Directly contact friction inside end to be worn with Left-wing Federation female connector 20, more improve pull bar 30 and the service life of Left-wing Federation's female connector 20.
The present invention uses process as follows；
Folder 50 first will be drawn to be placed on broaching machine guide pass, draw well the position of folder 50 according to broaching tool 80 Traffic control system, then, logical
Cross pressing plate 10 folder 50 to be drawn to be fixed on machine tool guideway 110 and prevent from drawing folder 50 left and right movement in the course of the work, simultaneously
The right-hand member with machine tool chief axis 100 of the left end of Left-wing Federation's female connector 20 is coupled tightly, the right-hand member of location-plate 90 is worked with broaching machine front end
Platform connects.Afterwards, will be put into by wire pulling method workpiece and be pressed in location-plate 90, and check and make swivel nut 40 and machine tool chief axis
100 and by wire pulling method workpiece whether coaxial inner conductor.Then, by broaching tool 80 left end through by wire pulling method workpiece endoporus and with
Right coupling sleeve 60 axial restraint connects, and starts broaching machine, and machine tool chief axis 100 drives pull bar 30 and broaching tool 80 to be combined axially and in rotation
Motion, after broaching tool 80 passes through from by the endoporus of wire pulling method workpiece completely, i.e. completes the processing to workpiece internal thread spline.
The content that the present invention does not describe in detail is prior art.
That does the preferred embodiment of the present invention above describes the illustration being only to make the present invention in detail.This
The technical staff of technical field that the present invention belongs to described detailed description of the invention can be carried out various amendment, supplement or
