Abstract
The utility model relates to a cylindrical machining cutter for a workpiece. The cylindrical machining cutter for the workpiece comprises a cutter arbor, wherein a cutter bit integrally formed with the cutter arbor is arranged at one end of the cutter arbor; an end face cutting edge is arranged at the free end of the cutter bit; a first cutting edge, a second cutting edge and a third cutting edge in the radial direction are arranged at the head part of the cutter bit; the second cutting edge is slantly extended towards a position at back of and above the end part of the first cutting edge; a sunken part lower than the first cutting edge is arranged at the tail end of the second cutting edge; and the third cutting edge is located on the circumferential wall surface of the sunken part. The cylindrical machining cutter can rapidly and accurately machine a plurality of cylindrical surfaces required to be machined on one part, time for cutter replacement and cutter blade adjustment is shortened, and the machined product quality is stable.
Description
Technical field
The utility model relates to a kind of cutter of excircle of workpiece processing.
Background technology
In prior art, on a part, there are the complex parts that multiple cylindricals need process a lot.The method of processing mainly adopts on milling machining center, carries out peripheral milling processing or multiple cylindrical operation break-downs is machined by the frock of harnessing an animal to a cart more with milling cutter.These processing methods need to be to tool setting repeatedly or to part multiple clamping, very loaded down with trivial details, wastes time and energy.Outer round surface roughness after processing is large, unstable product quality.
Summary of the invention
For the deficiencies in the prior art, the utility model provides a kind of cutter of excircle of workpiece processing, the utility model can carry out fast the multiple peripheries that need process on a part, accurate machining, has reduced the time of tool changing and adjustment blade, the constant product quality of processing.
The technical scheme solving the problems of the technologies described above is as follows:
The cutter of excircle of workpiece processing, comprise knife bar, one end of knife bar is provided with and the integrated cutter head of this knife bar, the free end of cutter head is provided with face cutting edge, the head of cutter head is provided with the first cutting edge, the second cutting edge and the 3rd cutting edge radially, the second cutting edge is to the oblique extension in back upper place of the end of the first cutting edge, and the end of the second cutting edge on cutter head is provided with a depressed part lower than the first cutting edge, and described the 3rd cutting edge is positioned on the circumference wall of this depressed part.
Described the 3rd cutting edge, after the oblique extension in back upper place, is connected with one end of the 4th cutting edge, and the other end of the 4th cutting edge extends to knife bar.
The axial angle of the extension line of described the second cutting edge and cutter head is 9 to 11 degree.
The axial angle of the extension line of described the 3rd cutting edge and cutter head is 12 to 13 degree.
Adopt such scheme, on cutter head, be provided with respectively the first cutting edge, the second cutting edge and the 3rd cutting edge radially, the second cutting edge is to the oblique extension in back upper place of the end of the first cutting edge, the end of the second cutting edge on cutter head is provided with a depressed part lower than the first cutting edge, and described the 3rd cutting edge is positioned on the circumference wall of this depressed part.Because the external diameter on the place cutter head of the first cutting edge, the second cutting edge and the 3rd cutting edge is all not identical, therefore, the external diameter of the workpiece that correspondence processes is not identical yet, thereby the utility model can carry out fast the multiple peripheries that need process on a part, accurate machining, reduce the time of tool changing and adjustment blade, the constant product quality of processing.
