Description
Technical field
The utility model belongs to cutter apparatus technical field, relates in particular to the anti-cutter of scraping of a kind of milling machine.
Background technology
Growing along with Design of Dies and processing and manufacturing level, for meeting the processing needs of difformity diverse location and different accuracy, derives miscellaneous machined cutter.Milling is as a kind of processing mode can not be substituted, and its progress plays vital effect to mold manufacturing industry.Meanwhile, milling cutter, as " weapon " of Milling Process, is again the key that can Milling Process exploit one's power.
In Design of Dies, counter sink is the design in a kind of hole of being often used to, for being fixed.It is actual is exactly a kind of desk-top concentric pylone of ladder that presents.That is: shoulder hole is divided into upper and lower two parts hole, and this two parts hole is concentric, and the diameter in just upper part hole is large, and the diameter in lower part hole is little.When trip bolt passes this hole, bolt portion is passed, and nut is pressed on ladder platform, and nut sinks in the large diameter hole of part all or in part, thereby realizes the function of counter sink.Anti-counter sink turns use around counter sink exactly, and the upper section diameter in hole is little, and lower section diameter is large, and screw is also upwards to install.
This anti-counter sink of Milling Process, just must use the anti-milling cutter of scraping, and the commercially available anti-milling cutter of scraping has two kinds at present, and the first is integral cutter, and tool bit part can stretch out and regain.When cutter reverses, cutter head is received in knife bar and passes through hole, and then cutter forward cutter head stretches out, and blade is housed on cutter head, and the large diameter hole of cutting counter sink is opened reversion again after completion of processing, and cutter head is regained, and cutter exits counter sink.Withdrawals because the main story that will realize cutter head is stretched out, reverse of this class cutter, structure is complexity comparatively, so can only realize single-blade, cuts.This just cause cutter radially and axially loaded uneven, cutting output and feed rate are all lower, process velocity is slow, and the blade on cutter head easily damages.Due to unbalance stress, cutter overhang can not be oversize, long if cutter stretches out, and is subject to the impact of cutter rigidity, can have processing cutter relieving, gently causes aperture size overproof, processes defective, heavy can damage cutter and even cause workpiece to be scrapped.The second is Split type cutter, is divided into knife bar and cutter head, and knife bar diameter is little, and tool bit diameter is large, studs with a blade, totally four on cutter head at interval of 90 °.When the anti-counter sink of Milling Process, this cutter is just first contained in knife bar on milling machine, and knife bar passes after via hole, then cutter head is loaded onto, and then realizes processing.After completion of processing, the lower cutter head of dismounting, knife bar exits workpiece.This cutter is because blade is embedded on cutter head, once breaks down cannot be changed, can cause whole cutter head to be scrapped, and cost is higher.And, in the face of different Material Processings, can not select the blade of unlike material to correspondence, can affect working (machining) efficiency.Have, four blades of this cutter are evenly set on cutter head every 90 ° again, and cutter head is rounded, and chip area is very little, and machining chips can not be discharged timely and effectively, can only take the mode of cutter lifting chip removal to carry out reciprocating processing, has affected to a great extent working (machining) efficiency.
Utility model content
The purpose of this utility model is to overcome the deficiency of above-mentioned technology, and provides a kind of milling machine the anti-cutter of scraping, and evenly cuts stressedly, improves working depth, and improves working (machining) efficiency, cuts down finished cost, and realizes twice laid cost-saving.
The utility model for achieving the above object, by the following technical solutions: the anti-cutter of scraping of a kind of milling machine, it is characterized in that: comprise cutter head and knife bar, described cutter head middle part is provided with cutter head screw thread via hole, described cutter head screw thread via hole is provided with quick positioning key around, described knife bar one end is provided with knife bar screwed hole, described knife bar screwed hole is provided with positioning spline around, described positioning spline coordinates with described quick positioning key, realize location fast, described cutter head screw thread via hole and knife bar screwed hole are bolted fixing; Described cutter head sidewall is provided with blade installation slot, in described blade installation slot, blade is installed, and described blade below is provided with the first chip area.
Preferably, the side of described the first chip area is provided with the second chip area.The metal fragment that cutting can be produced by two chip areas is discharged fast and effectively, can realize the high feeding and lasting cutting of milling, has improved lathe production capacity.
Preferably, the thickness of described blade installation slot is identical with the thickness of described blade, consistent size, and mounting groove and blade are provided with coaxial screwed hole, and bolt coordinates with screwed hole, blade is fixed in the mounting groove of cutter head.
The beneficial effects of the utility model are: the self-align cutter head of quick change, replaceable double blade processing, increases chip area, can select the cutter head of different-diameter according to different shoulder hole diameters, realizes a bar bull, effectively cost-saving.Blade is replaceable, the blade that in process, breaks down can directly more renew, cutter head is not subject to any loss, needn't change, and can according to the material of processing object need not, select dissimilar blade.Before each blade, increase chip area, greatly improved working (machining) efficiency, guaranteed the life-span of cutter.
