TECHNICAL FIELD

[0001] The utility model relates to a kind of multifunctional milling cutter of integrated milling and double chamfering, belong to equipment manufacturing technical field. BACKGROUND

[0002] In the field of process equipment manufacturing technology, the flange double chamfering is often required when machining the flange profile of workpiece. The chamfering has three functions: first, it is used to remove burrs; second, it improves the appearance of the part; third, it makes the assembly of the part easier. For double chamfering machining, the commonly used tool on the market is chamfering milling cutter. However, using chamfering milling cutter for machining can only achieve single-side chamfering. Therefore, when turning, the chamfering needs to be machined on both sides separately. This results in inconsistent chamfering size on both sides and low machining efficiency. SUMMARY

[0003] The utility model discloses a kind of multifunctional milling cutter of integrated milling and double chamfering, belong to equipment manufacturing technical field.

[0004] To solve the above technical problems, the utility model adopts the following technical scheme:

[0005] A kind of multifunctional milling cutter of integrated milling and double chamfering is composed of profile copying tool part, milling cutter part and tool shank part.

[0006] The profile copying tool part is connected with the milling cutter part, and the milling cutter part is connected with the tool shank part. The diameter of the milling cutter part is slightly smaller than that of the tool shank part. The tool shank part can be matched with the milling cutter chuck.

[0007] The diameter of the milling cutter part is the same as that of the bottom of the profile copying tool part.

[0008] The profile copying tool part includes profile copying tool part blade and profile copying tool part chip groove.

[0009] The milling cutter part includes milling cutter part blade and milling cutter part chip groove.

[0010] The profile copying tool part blade, profile copying tool part chip groove, milling cutter part blade and milling cutter part chip groove are all four.

[0011] The profile copying tool part chip groove and the milling cutter part chip groove are continuous.

[0012] The beneficial effects of the above technical scheme are:

[0013] 1. The utility model can form double chamfering at one time by using chamfering milling cutter for machining, without the need for machining on both sides separately. The chamfering size on both sides is consistent, which improves the machining efficiency, reduces the cost and is suitable for flange machining of various types of production parts.

[0014] 2、The utility model discloses a multifunctional milling cutter that integrates milling and double-side chamfering, which can solve the problem of insufficient number of tool positions of a numerical control lathe, reduce the cost of tools by 60% of the original cost, reduce the reverse milling chamfering process, and improve the pass rate of part processing to 100%. The processing efficiency of the tool is 2-3 times of the original processing efficiency, which greatly shortens the processing cycle of new parts and plays an important role in reducing costs and increasing efficiency for enterprises.

[0021] As shown in Figure 1 , a multifunctional milling cutter integrating milling and double-side chamfering is characterized in that it is composed of a profiled tool part 1, a milling tool part 2, and a tool handle part 3.

[0022] The profiled tool part 1 is connected to the milling tool part 2, and the milling tool part 2 is connected to the tool handle part 3. The diameter of the milling tool part 2 is slightly smaller than that of the tool handle part 3, and the tool handle part 3 can be matched with a milling cutter chuck.

[0023] The diameter of the milling tool part 2 is the same as the diameter of the bottom of the profiled tool part 1.

[0024] As shown in Figure 2 , the profiled tool part 1 includes a profiled tool part cutting edge 11 and a profiled tool part chip removal groove 12.

[0025] As shown in Figure 3 , the milling tool part 2 includes a milling tool part cutting edge 21 and a milling tool part chip removal groove 22.

[0026] The profiled tool part cutting edge 11, the profiled tool part chip removal groove 12, the milling tool part cutting edge 21, and the milling tool part chip removal groove 22 are all four.

[0027] The profiled tool part chip removal groove 12 is continuous with the milling tool part chip removal groove 22.
