Abstract
The utility model relates to a supersonic cutting tool comprising a tool bar and an inspissate cutter body. The tail end of the cutter body is provided with a connecting hole for a transducer; the middle lower part of the cutter body is provided with an energy conversion groove which is an open O-shaped hole; thereby, the transmission and conversion efficiency of ultrasonic energy is improved, and the problem that the original fine tool bar is easy to be fractured is solved. The supersonic cutting tool is mainly used for finish machining and hard material process.
Description
The utility model relates to a kind of cutting tool, particularly a kind of supersonic vibration cutting cutter.
Ultrasonic technique is used for machine cut processing aspect can improve machining accuracy, reduces roughness.And one of key of supersonic vibration cutting is a cutter.Chinese patent 91209962 discloses a kind of ultrasonic cutting lathe tool, and this cutter comprises knife bar and the cutter hub two parts that thicken.Have a vee-cut in the middle and lower part of cutter hub, it plays a part power conversion.Cutter hub tail end and transducer join.Transducer is with the form of compressional wave ultrasonic vibration can be passed to cutter hub, during through aforesaid V-arrangement power conversion groove, converts compressional wave to shear wave, is delivered to point of a knife by knife bar again.The inventor finds after reality is used: when knife bar was thick, the transmission and the conversion efficiency of this V-arrangement power conversion ditch were lower; When knife bar was thin, as internal lathe-tool, crackle appearred in the top of knife bar and cutter hub intersection and V-arrangement ditch easily, even fracture.Therefore, up to the present the ultrasonic cutting technology still is difficult to promote.
The purpose of this utility model is to provide a kind of transmission of ultrasonic energy and conversion efficiency higher at the existing in prior technology problem, the ultrasonic cutting cutter of knife bar working stability.
Solution of the present utility model is: the ultrasonic cutting cutter that is provided is made up of cutter hub two parts of knife bar and thickening.The tail end of cutter hub is provided with the transducer connection holes, and the middle and lower part of cutter hub is provided with the power conversion ditch, the O shape hole that this power conversion ditch is an opening.This O shape hole just is converted to horizontal ultrasonic vibration with comparalive ease when making longitudinal ultrasonic vibration from the cutter hub tail end through position, O shape hole, and has avoided excessive stress concentrated in the transmission of ultrasonic energy and transfer process.
Above-mentioned O shape hole can be an elliptical aperture, but circular hole preferably is beneficial to processing.The diameter of circular hole can be selected in the 8-40mm scope, generally speaking, can select less aperture when knife bar is thin; Can select bigger aperture when knife bar is thick.
Compared with prior art, advantage of the present utility model is: easily processing; The transmission and the conversion effect of energy are better, the knife bar working stability, and service life is longer.In addition, this cutting tool simple in structure can be directly used in common machining lathe.
Below in conjunction with accompanying drawing content of the present utility model is illustrated.
Fig. 1 is a structure chart of the present utility model.
Fig. 2 is the left view of Fig. 1.
Fig. 1, Fig. 2 have provided the structure of a billmpse tool.The cross section of cutter hub 1 and knife bar 2 is rectangle, and its width is 22mm.The thickness of knife bar 2 is 15mm, long 46mm; The thickness of cutter hub 1 is 46mm, long 80mm.Cutter head 3 is welded on the knife bar 2.The tail end of cutter hub 1 has a hole 4, is used to connect transducer; The middle and lower part of cutter hub 1 has a circular hole 5, has a narrow groove 6 to the lower edge from the below of circular hole 5, and the diameter in hole 5 is 20mm.The inventor has carried out actual processing experiment with this cutter, and proving effect is good.
