Abstract
The invention provides a cyclone milling cutter which can be quickly replaced without re-aligning after the cutting edge of the milling cutter is abraded. The cyclone milling cutter comprises a cutter disc, and one or more cutters which are arranged in the circumferential direction of the cutter disc; the cutters are connected with the cutter disc in a dismountable way; when the cutters are abraded or damaged, identical cutters can be used for replacing the abraded or damaged cutters so as to carry out the processing continuously without re-aligning.
Description
Technical field
The present invention relates to Whirlwind milling cutter.
Technical background
It is the topping machanism of the High-speed machining screw thread supporting with machine tool, worm screw, sphere that whirlwind mills, and it is with the carbide alloy shaping blades that is contained on the high speed rotary head, mills out the Screw thread process method of screw thread, worm screw, sphere from workpiece.Because of its milling speed height (speed reaches 400m/min) working (machining) efficiency fast, in the process cutting splash gains the name as whirlwind-whirlwind mills.Whirlwind mills can be realized doing cutting, heavily loaded cutting, difficult-to-machine material and superhigh-speed cutting, and consumption of power is little, and surface roughness can reach Ra0.8 μ m.Machine spindle speed is slow, so machine tool motion precision height, dynamic stability are good, is a kind of advanced person's cutting working method.Whirlwind mills and can be used to screw mandrel, worm screw, sphere are processed.
Existing Whirlwind milling cutter comprises cutterhead, is fixed on the circumferential a plurality of blades of cutterhead, and blade has only a cutting edge; Its blade row and blade are solder joint.For Whirlwind milling cutter is carried out accurate sharpening, need special sharpening lathe, this lathe very expensive (about 300,000 yuan).If sharpening by hand, size, profile of tooth, roughness just do not reach requirement, after the blade cut sharpening decreases, promptly will reduce production efficiency to its reconditioning or replacing.The more important thing is that the Whirlwind milling cutter behind sharpening or the replacing blade just need tool setting again, and the tool setting process is very complicated after loading onto cutterhead, also can not reach sharpening or tool changing preceding size and form and position tolerance.
Summary of the invention
The purpose of this invention is to provide and to change rapidly after a kind of blade cut sharpening decreases and the Whirlwind milling cutter of tool setting again.
This Whirlwind milling cutter comprises cutterhead, is arranged on the circumferential one or more blades of cutterhead, and blade becomes dismounting to be connected with cutterhead.When blade abrasion or damage, take off the same blade of replacing and can work on tool setting again.
As improvement, blade has two or more and is distributed on the circumferential cutting edge of blade; Blade becomes dismounting to be connected by the jockey that passes blade axis with cutterhead.Blade has a plurality of cutting edges, and when cutting edge wearing and tearing or damage, rotating this blade around blade axis is that replaceable another cutting edge works on, simultaneously, because it is circumferential that two or more are distributed on the cutting edge blade, blade after blade axis is rotated, tool setting again.
As improvement, that blade has is identical with cutting edge quantity, be distributed on the circumferential locating surface of blade; Be provided for placing the recess (blade fixed position) of blade on cutterhead, the inboard of fixed position has the supporting surface that contacts with the locating surface of blade respectively; The bottom surface of fixed position contacts with blade one end face.Supporting surface contacts with locating surface, and the cutting force that blade is subjected to acts on the cutterhead by supporting surface, has guaranteed the reliably working of blade; The bottom surface of fixed position and supporting surface also blade have played positioning action.
Best described blade has three or four cutting edges.When three on blade or four cutting, the mutual angle of three locating surfaces (or supporting surface) is 60 degree, and blade and cutterhead are easy to processing, and when blade and cutterhead work stressed evenly.
Best described blade is 4-12.Each blade adopts the carbide alloy sharpening to form, and the thread tooth that cutting is come out is more accurate, and surface smoothness is relatively good.Because of knife number is many, so can adopt bigger cutting data, production efficiency obviously improves.
Above-mentioned Whirlwind milling cutter, cutterhead has endoporus, and described blade is arranged on the endoporus periphery, and this promptly is interior Whirlwind milling cutter.
Above-mentioned Whirlwind milling cutter, jockey are bolt.

Specific embodiments
The present invention is further detailed explanation below in conjunction with the drawings and specific embodiments.
Embodiment 1 (outer whirlwind milling cutter):
Referring to Fig. 1-6, Whirlwind milling cutter comprises cutterhead 1, is arranged on the circumferential a plurality of blades 2 that form with the carbide alloy sharpening of cutterhead.
Circumferentially evenly be provided for a plurality of fixed positions (recess) 8 of fixturing blade at cutterhead, the inboard of fixed position has three supporting surfaces 9 that contact with the locating surface of blade respectively.The bottom surface of fixed position contacts with matrix (blade) end face.The mutual angle of three locating surfaces (or supporting surface) is 60 degree.
In the present embodiment 1, each blade has 3 cutting edges, and when cutting edge wearing and tearing or damage, unclamping bolt 6 these blades of rotation is that replaceable another cutting edge works on, without tool setting, to improve working (machining) efficiency.
A plurality of profiles of tooth that blade cut is come out are more accurate, and surface smoothness is relatively good.Because of knife number is many, so can adopt bigger cutting data, production efficiency obviously improves.
Embodiment 2 (interior Whirlwind milling cutter):
Referring to Fig. 3,4,5,7,8, Whirlwind milling cutter comprises cutterhead 1 with endoporus 10, be arranged on the endoporus periphery 6 blades 2 that form with the carbide alloy sharpening.
Circumferentially evenly be provided for a plurality of fixed positions (recess) 8 of fixturing blade at the cutterhead of endoporus periphery, the inboard of fixed position has three supporting surfaces 9 that contact with the locating surface of blade respectively.The bottom surface of fixed position contacts with matrix (blade) end face.The mutual angle of three locating surfaces (or supporting surface) is 60 degree.
