Abstract
The invention relates to an external circle molding milling cutter. The external circle molding milling cutter comprises a cutter bar, wherein one end of the cutter bar is provided with a cutter bit integrated with the cutter bar, the free end of the cutter bit is provided with an end surface cutting edge, the head part of the cutter bit is provided with a first radial cutting edge, a second radial cutting edge and a third radial cutting edge, the second cutting edge obliquely extend to the back upside of the end part of the first cutting edge, a sinking part lower than the first cutting edge is formed at the end of the second cutting edge of the cutter bit, and the third cutting edge is located on the circumferential wall surface of the sinking part. The external circle molding milling cutter can rapidly and accurately process multiple external circle surfaces required to be processed of one part, the cutter replacement and blade adjusting time is shortened and the processed product has stable quality.
Description
Technical field
The present invention relates to a kind of cylindrical profile milling cutter.
Background technology
In prior art, a part have the complex parts that multiple cylindrical need process a lot.The method of processing mainly to adopt in Milling Machining in the heart, carries out peripheral milling processing or to multiple cylindrical operation break-down machine by frock of harnessing an animal to a cart more with milling cutter.These processing methods need to repeatedly tool setting or to part multiple clamping, very loaded down with trivial details, waste 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 invention provides a kind of cylindrical profile milling cutter, the present invention can carry out the multiple peripheries that need process on a part fast, accurate machining, decrease tool changing and adjustment blade time, the constant product quality of processing.
The technical scheme solved the problems of the technologies described above is as follows:
Cylindrical profile milling cutter, comprise knife bar, one end of knife bar is provided with the integrated cutter head with 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 radial cutting edge, the second cutting edge and the 3rd cutting edge, 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 3rd cutting edge is positioned on the circumference wall of this depressed part.
Described 3rd cutting edge is rearwardly and upwardly after oblique extension, and be connected with the 4th one end of cutting, the other end of the 4th cutting edge extends to knife bar.
The extension line of described second cutting edge and the angle of cutter head axis are 9 to 11 to spend.
The described extension line of the 3rd cutting edge and the angle of cutter head axis are 12 to 13 to spend.
Have employed such scheme, cutter head is provided with the first radial cutting edge, the second cutting edge and the 3rd cutting edge respectively, 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 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, thus the present invention can carry out the multiple peripheries that need process on a part fast, accurate machining, decrease the time of tool changing and adjustment blade, the constant product quality of processing.
Accompanying drawing explanation
Fig. 1 is the front view of cylindrical profile milling cutter of the present invention;
In accompanying drawing, 1 is knife bar, and 2 is cutter head, and 3 is face cutting edge, and 4 is the first cutting edge, and 5 is the second cutting edge, and 6 is the 3rd cutting edge, and 7 is the 4th cutting edge.
Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention will be further described.
With reference to Fig. 1, cylindrical profile milling cutter of the present invention, comprise knife bar 1, one end of knife bar 1 is provided with the integrated cutter head 2 with this knife bar, the free end of cutter head 2 is provided with face cutting edge 3, the head of cutter head 2 is provided with the oblique extension in back upper place to the end of the first cutting edge 4 of the first radial cutting edge 4, second cutting edge 5 and the 3rd cutting edge 6, second cutting edge 5, and the extension line of the second cutting edge 5 and the angle α of cutter head 1 axis 9 to 11 spend.The end of the second cutting edge 5 on cutter head 2 is provided with a depressed part lower than the first cutting edge, and described 3rd cutting edge 6 is positioned on the circumference wall of this depressed part.Described 3rd cutting edge 6 is rearwardly and upwardly after oblique extension, and the one end of cutting 7 with the 4th is connected, and the other end of the 4th cutting edge 7 extends to knife bar 1.The extension line of the 3rd cutting edge 6 and the angle β of cutter head 1 axis 12 to 13 spend.
