Detailed Description

The present invention will be described in detail below with reference to the accompanying drawings.

In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the utility model and are not intended to limit the utility model.

Example 1

As shown in fig. 1 to 6, the chamfer cutter according to the present embodiment includes a cutter body 1, an inner cavity 2 is provided in the cutter body 1, the inner cavity 2 has a side wall in an annular arrangement and is approximately conical, the inner cavity has a small end 9 and a large end 10, the small end 9 and the large end 10 are arranged oppositely, the large end 10 is arranged in an open manner, the small end 9 is arranged in a closed manner, and a connecting portion 11 is connected to an outer side of an end portion of the cutter body 1 away from the large end 10.

When the chamfering tool works, the connecting part 11 is connected to a processing machine 12, the processing machine 12 drives the connecting part 11 to rotate, and the connecting part 11 drives the chamfering tool to rotate to cut the periphery of the tail end of the workpiece to be processed.

At least three cutters 3 are circumferentially arranged on the side wall of the inner cavity 2, and all the cutters 3 are arranged in an unequal manner.

As shown in fig. 4, in general use, three cutters 3 are circumferentially arranged on the side wall of the inner cavity 2, and are defined as a first cutter 4, a second cutter 5 and a third cutter 6 in sequence, an included angle a between the first cutter 4 and the second cutter 5 is greater than an included angle B between the second cutter 5 and the third cutter 6, where a is not equal to B.
