Above-mentioned cutter head 1 is provided with the first conical surface transition section 6 with the link of blade 2.
Above-mentioned blade 2 is little with the link of cutter head, and described blade 2 is large with the link of handle of a knife, and the blade tapering is between 1:10～1:16.
Above-mentioned blade 2 is provided with changeover portion 5 with the link of cutter head 1.
Above-mentioned blade 2 is provided with the second conical surface transition section 9 with the link of handle of a knife 3, and described handle of a knife 3 is connected with blade 2 by the second conical surface transition section 9.
Above-mentioned handle of a knife 3 is provided with block plate 10 with the link of blade 2, and described conical surface transition section 9 is connected with block plate 10.
Also comprise cooling package, described cooling package comprises the first cooling passage, the second cooling passage and the 3rd cooling passage that is communicated with successively, described the first cooling passage connects handle of a knife and blade, described the second cooling passage is arranged on the blade and with the first cooling passage is vertical and arranges, described the 3rd cooling passage be arranged on the blade and the outlet of the 3rd cooling passage towards cutter head.
The other end of above-mentioned handle of a knife 3 is provided with wealthy mouthful of groove 12, and the entrance of described the first cooling passage is communicated with coolant bottle by wealthy mouthful of groove 12.
Be provided with orthogonal the first plane of orientation 13 and the second plane of orientation 14 on the above-mentioned handle of a knife 3.
Described blade installation slot 4 is triangle.
The technique effect that the utlity model has is:
1, the utility model adopts the mode of blade and handle of a knife axial line phase deviation, make the more close workpiece centre axle of the blade point of a knife that is installed in this knife bar, thereby the sleeve pipe specification limit of some lathe in machining is increased greatly, improved the adaptability of this type of numerically controlled lathe, the superior function of this type of numerically controlled lathe is brought into play.
2, be equipped with changeover portion between the utility model cutter head, blade, the handle of a knife, reduced the local stress of knife bar, strengthened knife bar intensity.
3, the utility model adopts the syllogic cooling passage, in the situation that realizes the cooling fluid conveying function, has reduced difficulty of processing, produces in enormous quantities for knife bar and provides convenience.

The specific embodiment
Such as Fig. 1, Fig. 2 and shown in Figure 3, the utility model comprises a cutter head, a blade and a handle of a knife, and three parts link and form an integral body, and wherein cutter head and blade are same axial line, and blade and handle of a knife axial line deviation are d.Wherein the cutter head front end is provided with blade installation slot, and blade and handle of a knife inside are equipped with cooling passage.During lathe work, the lathe coolant pump arranges pipeline by lathe self cooling fluid is transported to knife bar the first cooling passage entrance, cooling fluid flow through the second cooling passage and the 3rd cooling passage finally are ejected on cutter head and the workpiece, to reach the effect of cooling blade and workpiece.The handle of a knife front end is provided with block plate, and the handle of a knife cylindrical side is provided with two plane of orientations, location when being used for installing.Handle of a knife is injected in the tool rest hole, use bolt to be fixed.Knife bar is installed on the numerically controlled lathe, and the axial line deviation of blade and handle of a knife just can make the X stroke of blade cusp increase d, thereby the specification scope of lathe processing sleeve pipe is increased, and makes numerically controlled lathe can carry out the internal thread machining of less standard sleeve pipe.
