Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without any creative effort belong to the protection scope of the present invention.

As shown in fig. 1 and 2, an annular groove machining tool bit includes a cutting mechanism and an injection mechanism, the cutting mechanism includes a tool post 1 and a plurality of tool posts 4 disposed on the tool post 1, the end surfaces of the tool posts 4 facing the rotation direction are provided with blades 5, the blades 5 on each tool post 4 respectively correspond to a cutting radius within a certain range, and the top of the tool post 4 is provided with a slope portion facing away from the rotation direction; the injection mechanism is arranged in the tool apron 1, and a water spray hole 6 of the injection mechanism is arranged on the slope part.

In practice, the tool apron 1 is provided with the connecting through hole 3, and when the tool apron is used, the tool apron 1 is fixedly connected with a driving mechanism on a lathe through a bolt, and then the driving mechanism drives the tool bit to integrally rotate. After the tail end of the cutter post 4 is abutted to the cutting position, the rotating cutter post 4 and the rotating blades 5 cut the cutting position, each blade 5 cuts an annular groove with a certain width, and the blades 5 jointly act to cut the annular groove with the required groove width. In the cutting process, cutting fluid is sprayed from the water spray holes 6, the cutting position is lubricated and cooled, the distance between the water spray holes 6 and the cutting position is about 1mm in practice, spray liquid can not splash in the rotating process, in addition, an annular groove is generated in the cutting process, the cutter post 4 and the water spray holes 6 are both positioned in the annular groove, and spray splashing can not be caused by centrifugal force generated by rotation.

In this embodiment, four knife columns 4 are symmetrically arranged on the knife holder 1, one blade 5 is arranged on the first knife column, two blades 5 are respectively arranged on the second knife column, the third knife column and the fourth knife column, and the blade 5 on the first knife column is higher than the blades 5 on the second knife column, the third knife column and the fourth knife column. In practice, the blade 5 on the first tool post is slightly higher than the blades 5 on the other tool posts 4 by 0.5mm, that is, one blade 5 performs a certain cutting and breaking action on the cutting part. The blades on the first tool post are respectively arranged between the two blades on the second tool post, the third tool post and the fourth tool post. I.e. the blade 5 of the first blade column is correspondingly arranged at the middle position of the positions of the two blades 5 of the other blade columns 4. The blade 5 is detachably arranged on the knife post 4 through a screw, and is convenient to detach and install. The distance between the four knife columns 4 is large, so that cutting chips are convenient to discharge.

In practice, the cutting radius ranges of the blades 5 on the tool posts 4 are provided with a certain overlap range. That is, the cutting ranges of the blades 5 are overlapped to a certain extent, so as to avoid the occurrence of uncut positions, for example, the cutting radius range of the first knife column is 19-21mm, the cutting radius range of one blade of the second knife column is 17-19.5mm, and the cutting radius range of the other blade of the second knife column is 20.5mm-22mm.
