Description
Technical field
The utility model relates to machinery and uses the drill bit field, is specially a kind of drill bit with auxilliary cutter ring.
Background technology
Mechanical part commonly used in the drill bit machinery industry, it is to go out through hole or blind hole in order to drilling on the solid material, and can be to the cutter of existing hole reaming.Drill bit is made up of tool rest, handle of a knife, cutter head, and it is limited in one's ability to hole when the drill bit of prior art runs into comparatively hard material, and probing is difficulty comparatively.
The utility model content
The utility model purpose provides a kind of drill bit with auxilliary cutter ring, to solve prior art bit bore problem limited in one's ability.
In order to achieve the above object, the technical scheme that the utility model adopted is:
A kind of drill bit with auxilliary cutter ring; Include tool rest, be connected the tool rest rear end handle of a knife, be socketed in the anterior cutter head of tool rest; It is characterized in that: said cutter head comprise be socketed in the anterior dish type section of tool rest, through tapered portion be connected dish type section front end the first right cylinder section, be connected the first right cylinder section front end and with respect to the second right cylinder section of the first right cylinder section undergauge through chamfered section; The said second right cylinder section front end is shaped to point of a knife; The anterior outer wall of the second right cylinder section forms external screw thread, also comprises auxilliary cutter ring, and said auxilliary cutter ring inwall forms internal thread; Said auxilliary cutter ring is screwed on the anterior outer wall of the cutter head second right cylinder section, and auxilliary cutter ring outer wall is connected with a plurality of auxilliary cuttves that tilt to cutter head point of a knife direction respectively.
The utility model is simple in structure, is easy to realize that cutter head is divided into dish type section, the first right cylinder section and the second right cylinder section; On the anterior outer wall of the second right cylinder section, screwed togather auxilliary cutter ring; Be connected with auxilliary cutter on the auxilliary cutter ring, so in use, can the material extruding in the place ahead be discerped through the auxilliary cutter on the auxilliary cutter ring; And then can effectively improve the boring ability of drill bit, auxilliary simultaneously cutter can take off auxilliary cutter ring easily when damaging and change.
