Description
Technical field
The present invention relates to numerical control machining cutter technical field, specifically a kind of switching dress that lathe tool can be transformed into boring cutter
Put.
Background technology
With the fast development of modern industry, boring processing machine adds aspect use it is more and more frequent, usual precision compared with
High hole and cylindrical, is required for boring processing to complete, but the species of boring cutter is more and expensive, and general processing producer can only
Lay in regular size boring cutter in case using.And for the producer of single and mini-batch production, multi-item production, passed through in terms of boring processing
Various difficult processing situations can be often run into, such as end face seal groove, radially inner channel.In this case it can only often go
Special cutting tool for boring is customized, processing cost so can be not only greatly improved, and the customization time is long, has a strong impact on the processing of product
Cycle.
Some producers are avoided boring processing scheme, entered by the way of numerical control milling when running into above-mentioned difficult processing situation
Row processing, but surface roughness, axiality and the circularity of the seal groove that goes out of Milling Process or internal channel etc., process gap with boring
It is larger, it is impossible to meet technological requirement.
Also turning cutting tool is directly installed on what is used on head for boring bar by someone, but incorrect installation method can not be smoothly
It is processed.For example, because the position of head for boring bar clamping boring cutter bar is cylindrical type interface, for the lathe tool of square is loaded, they adopt
The method that turning cutting tool shank is lathed to cylindrical type is taken, but so, the centre-height of cutter deviate from boring head revolution
Heart line, can accelerate tool wear in processing, easily squeeze broken point of a knife, and processing dimension can not accurately ensure.
The content of the invention
For overcome the shortcomings of high processing costs present in prior art, crudy it cannot be guaranteed that, the present invention is proposed
A kind of boring cutter and method for remanufacturing changed a social system by lathe tool.
The boring cutter changed a social system by lathe tool is made up of switching device and cutter, wherein, the cutter is in the prior art
The handle of a knife tail end of end face recessing bit mill out the plane contour with point of a knife, then by the tail end be lathed with switching device
The consistent semi-cylindrical of type, the plane and point of a knife of the semicolumn is contour.Transferred on the external diameter and head for boring bar of described switching device
The internal diameter in hole is identical；There is semicircular endoporus in the switching device, described in axis insertion of the endoporus along the switching device
Switching device two ends, form the inner mold of the switching device.
The radius of the inner mold of the switching device is identical with the radius of the mounting rod of cutter.By the switching device solid
The external peripheral surface of side is processed into plane, and the mounting hole of lock-screw is distributed with this plane.In the switching device
The circumferential surface of one end has positioning table, for limiting the rigging position between switching device and the head for boring bar.
The diameter of the positioning table is than the big 5mm of diameter of switching device, and axial length is 3mm.
The detailed process of the transformation of the way proposed by the present invention boring cutter is：
Step 1, switching device semi-finished product are made.During making, got on the bus in blank process the face of cylinder first, the face of cylinder with
The interior cavity gap of transfer hole on head for boring bar coordinates.Inner Vehicle Processing on the face of cylinder goes out positioning table.Obtain switching device half
Finished product.
Step 2, milling switching device outside fix face.Milling is milled out in the circumferential surface of obtained switching device semi-finished product
The outside fix face of switching device.
Step 3, hole is inscribed in the switching device of processing and milling switching device.Line is got out below switching device semi-finished product axis
The wire hole of cutting.Using the through hole as the wire hole of wire cutting, using conventional wire cutting method, in the switching device half

The small 3mm of radius of semi-finished product circumference is put, the semicircle endoporus that wall thickness is 3mm is formd on the switching device semi-finished product.Institute
State outside fix face of the plane parallel to milling switching device of semicircle endoporus, and the semicircle endoporus and switching device half into
The outer circumference surface of product is coaxial.
Step 4, the locking screw keyhole of switching device is processed.By milling machine, using conventional method in the switching device half
2~3 countersunk head locking screw keyholes are processed on the outside fix face of finished product.Obtain switching device.
Step 5, it is determined that transformation of the way Lathe tool tip height.The handle of a knife of end face recessing bit is blocked by required length.Will be described
The horizontal clamping of lathe tool is changed a social system on the workbench of milling machine, and the cutting for making the transformation of the way lathe tool is upwardly, is measured using conventional method
Height of the transformation of the way Lathe tool tip apart from the milling machine table table top.
Step 6, mill out the plane parallel with milling machine table table top in the transformation of the way lathe tool tail end, and make the plane with
Change a social system Lathe tool tip contour；The axial length of the plane is 50mm.The plane is the locating surface coordinated with switching device.
Step 7, clamping transformation of the way lathe tool.The transformation of the way lathe tool clamping for having locating surface will be made on lathe, make the transformation of the way car
