Abstract
A method for a three-coordinate numerical control center to machine a thread on a large special-shaped part overcomes the shortcomings of the prior art, namely the large special-shaped part is firstly fixed on a radial drill through a special clamp, further a threaded base hole is drilled, and then the large special-shaped part is machined by utilizing a screw tap. However, a product after heat treatment still deforms extremely easily, a thread is changed, and product quality is hard to ensure. The method is characterized in that a FANUC system is established, defined and set, a post-processing documents are utilized; digital analog is established according to a drawing; and thread machining and numerical control machining programs are established. The method has the advantages of solving the problems that the thread on a large long rod special-shaped part can not be machined on a rotary device and the thread is machined on the large special-shaped part and especially achieving machining of MJ inner and outer threads of a product after the heat treatment (HRC48-55). The precision and roughness of thread machining are high, the threads are machined after quenching, thread size is easy to control, and the product quality is ensured. Time is saved, the programs are conveniently programmed, and the method is used for the three-coordinate numerical control center to machine the threads on the large special-shaped part.
Description
Technical field
The present invention is a kind of processing method of screw thread, particularly the method for three-dimensional numer centre machining screw on large scale special-shaped.
Background technology
In the prior art, machining screw can't realize on apparatus for rotating on large scale special-shaped.So on large scale special-shaped during machining screw, must be before heat treatment (before quenching) earlier with the large-scale special clamps on radial drilling machine, drilling screw thread datum hole (because of being to be difficult to process this screw thread after the quenching) again; The workman uses the screw thread special screw tap to process by hand then; Even like this, product still very easily produces distortion after the heat treatment, and the screw position relative datum changes, and screw thread itself also has little distortion, and product quality is difficult to guarantee.
Summary of the invention
In order to solve the weak point in the above-mentioned background technology, the purpose of this invention is to provide a kind of method of numer centre machining screw.Technical solution of the present invention is:
1, creates definition and the FANUC system is set with the rearmounted file of handling;
2, set up digital-to-analogue according to drawing;
3, create screw thread processing and nc program.
Following procedure is the part of the procedure that provides to certain piston rod MJ48X1.5-4H5H strengthened thread fine finishining:
The present invention compares the advantage that prior art has:
1, realizes machining screw at numerical control machining center, the old and new's product development and production are had the meaning of particular importance.Especially the numer centre milling thread has been realized the problem that screw thread can't be processed on the large-scale stock shaped piece on apparatus for rotating.
2, solve the problem of machining screw on large scale special-shaped, needing especially to have realized the product of (HRC48～55) processing MJ internal and external threads after the heat treatment.Digital control processing accuracy of thread, roughness height, the screw thread processing dimension is easy to control.
3, only set up the local digital model according to products characteristics and save time, make things convenient for program composition.
Utilize numerical control device to make screw thread, precision is very high, and is after quenching, to process, and product quality is guaranteed.
Use the screw cutter converted products, samely can process the internal and external threads of different-diameter, different pitch to cutter, the cutter versatility is good; Like diameter of phi 20 screw cutters, can process the pitch of Φ more than 24 and be 0.5～2.5 all common with strengthen internal thread.Accuracy of screw machining utilizes equipment cutter compensation device control, can the machining high-precision screw thread, and be certain piston rod MJ48X1.5-4H5H double precision strengthened thread fine finishining cutter rail like Fig. 4.

The drawing of accompanying drawing of the present invention is explained as follows:
Fig. 1 is large scale special-shaped upward needs processing Y-15 screw thread position schematic perspective view.Wherein 1 be MJ38X1.5-4H5H.
Fig. 2 is large scale special-shaped upward needs processing C-33 screw thread position schematic perspective view.Wherein 2 be MJ48X1.5-4H5H.
Fig. 3 is a MJ36X1.5-4H5H double precision strengthened thread model schematic perspective view.
Fig. 4 is that the MJ48X1.5-4H5H double precision is strengthened internal thread fine finishining cutter rail sketch map.
Fig. 5 is a M16X1-5H external screw thread fine finishining cutter rail sketch map.
Fig. 6 is MJ48X1.5-4H5H internal thread cutter rail, emulation sketch map.
The specific embodiment
The present invention does further to detail below in conjunction with accompanying drawing and embodiment:
1, creates definition and the FANUC system is set with the rearmounted file of handling
Use UGNX software, set up one of customization and be suitable for the new post processor file particular tool of FANUC control system that FANUC system three-dimensional machining center equipment is used, i.e. three program post processors.Be used to process the internal and external threads nc program through direct generation of new program post processor.
2, set up digital-to-analogue according to drawing
Only set up the local digital model according to products characteristics.Set up local digital-to-analogue and save time, make things convenient for program composition, and operator's field machining and tool setting are simple, quick.
3, create screw thread processing and nc program
With digital-to-analogue procedure establishment feed, withdrawing, be traditionally arranged to be spiral arc forward and back cutter, lead angle is consistent with the lead angle of processed screw thread, and Tool in Cutting is steady like this, and cutter life prolongs.The screw thread procedure can be worked out according to specific product separately.
Supply three-dimensional numer centre machining screw on large scale special-shaped to use.
