Detailed description of the invention
Below in conjunction with accompanying drawing, embodiments of the invention are described in further detail.
Fig. 1 is to Figure 6 shows that structural representation of the present invention.
Reference numeral is wherein: feed liquor sprue A, directional inclination runner B, mouth spray C, threaded mounting hole D, cutter bar body 1, cylindrical shank portion 11, cone mast portion 12, front plan 12a, tangent plane platform 121, smooth curved surface 121a, recessed district 122, location, extension slot 123, the first side wall 124, milling cutting insert 2, cutting edge 21, special screw 3.
As shown in Figures 1 to 6, the taper thread milling cutter with interior cooling structure of the present invention, comprise cutter bar body 1, cutter bar body 1 is made up of with cone mast portion 12 cylindrical shank portion 11 of one machine-shaping, the front end milling in cone mast portion 12 is shaped with the tangent plane platform 121 being beneficial to installation and chip removal, the anterior detachable separating type of this tangent plane platform 121 is fitted with the milling cutting insert 2 of structure triangular in shape, milling cutting insert 2 is at least shaped with a cutting edge 21, and this milling cutting insert 2 arbitrarily angled equipped time only have a cutting edge 21 to be in machining position, the cutting edge angular bisector and cutter bar body 1 center line that are in machining position have certain angle simultaneously, it is not traditional vertical angle.Be shaped with internal coolant runner in cutter bar body 1, the liquid outlet of this internal coolant runner points to machining position, and the combination that matches of cutter bar body 1 and milling cutting insert 2 constitutes the screw cutter structure of taper type internally cooled.In workpiece process, milling cutter cut time can produce very high temperature, high temperature can cause blade or workpiece ablation, cause the workpiece quality of processing difference and milling cutter short for service life.Usually adopt the method for external cooling tube in conventional art, spray cooling fluid by cooling tube to working position and realize cooling, this method has the defect being difficult to overcome, and cooling effect is bad, and deviation is often understood in the position of sprinkling.Cutter bar body 1 of the present invention is shaped with internal coolant runner directly directedly can carry out flushing cooling to machining position, and thus its cooling effect is better.Then because cooling fluid flows through in cutter bar body 1 body, therefore cutter bar body 1 also can be cooled timely and is in normal operating temperature all the time.The cooling of inner-cooled is rinsed also has a large advantage, can be washed away by the chip of cutting timely exactly, ensures to cut the clean and tidy of environment, thus improves the machining accuracy of screw thread.Cutter bar body 1 of the present invention and milling cutting insert 2 adopt the assembling of detachable separating type, improve the equipped flexibility of cutter and interchangeability, no matter that cutter bar body 1 or milling cutting insert 2 damage whole cutter all can not be caused to scrap, cutter bar body 1 by and milling cutting insert 2 assembling with different cutting edge 21 can meet the process requirements of sizes taper thread, thus its applicability is wider.The present invention is simple for structure, with low cost, has good cooling results, and the feature of machining accuracy height and long service life, is suitable for the demand of multiple taper thread processing.
In embodiment as shown in Figure 1, internal coolant runner of the present invention comprises the feed liquor sprue A that the central axis along cylindrical shank portion 11 is shaped with and extends with the inclination be shaped with in cone mast portion 12 the directional inclination runner B being communicated with feed liquor sprue A, liquid outlet is the mouth spray C of directional inclination runner B, and this mouth spray C to be positioned on tangent plane platform 121 and to point to machining position.
The afterbody that above-mentioned tangent plane platform 121 extends back has the smooth curved surface 121a in arcs of recesses.The more convenient chip removal of smooth curved surface 121a energy, and chip removal resistance when cooling fluid is rinsed can be reduced.
Of the present invention in order to ensure the fastness that milling cutting insert 2 is installed, in embodiment, tangent plane platform 121 is shaped with the location of matching with milling cutting insert 2 and is recessed into district 122, milling cutting insert 2 is fixedly mounted on this location and is recessed in district 122, recessed district 122, location has two sidewalls, and two sidewalls turn location with two frontier defenses of triangular milling blade 2 respectively and match.Recessed district 122, location is the recessed platform of turning, and two sidewalls one in recessed district 122, location are relatively long, and another is relatively short.
In order to ensure that two sidewalls can not affect the placement of milling cutting insert 2, making location be recessed into district 122 and coordinating with the effective of milling cutting insert 2, in embodiment, the junction of 122 two sidewalls in recessed district, location is shaped with the extension slot 123 holding cutting edge 21.
Described milling cutting insert 2 of the present invention is shaped with three corner positions that three cutting edges, 21, three cutting edges 21 lay respectively at milling cutting insert 2.Be shaped with three cutting edges 21 and can expand the scope of application of the present invention further, cutting edge 21 can be identical, also can have different screw chasing angles.
In embodiment, the center of milling cutting insert 2 is shaped with assembling through hole, and recessed district 122, location is shaped with threaded mounting hole D, and milling cutting insert 2 is recessed in district 122 through the dismountable location that is fitted in of special screw 3.
The center line of threaded mounting hole D departs from the central axis in cone mast portion 12.The central axis of threaded mounting hole D in the central axis in cone mast portion 12, in order to a cutting edge 21 can be had when ensureing that milling cutting insert 2 is installed to be in cutwork position, so two lines non-intersect.
The first side wall 124 in two sidewalls in recessed district 122, location is 55 degree to 58 degree with the slanted angle of the front plan 12a in cone mast portion 12, and the angle of any two adjacent edges of milling cutting insert 2 is 60 degree.Article two, the angle between sidewall is 60 degree.The present invention is through test of many times, and the first side wall 124 is best effort angle with the slanted angle of the front plan 12a in cone mast portion 12 55 degree to 58 degree time.
Product structure of the present invention is unique, can be suitable for multiple taper thread and cut, have machining accuracy high, the feature that milling rigidity is strong, can provide sound assurance for the processing of efficient stable.
