Abstract

The invention discloses a polishing tool which comprises a hilt. The hilt is connected with a blank matrix by an avoiding surface, a blade is welded at the front end of the blank matrix, a straight groove is formed in the blank matrix, a cutting edge is arranged in the straight groove, a cutting head is arranged on the cutting edge, the cutting edge and the cutting head are integrally formed, and an arc transition surface is connected onto the blade. The polishing tool has the advantages that the polishing tool is used for machining sealing rings, each sealing ring can be formed at one step, the smoothness of the sealing rings can be improved, the sealing rings are good in sealing effect, and the cost can be saved owing to the welded blade.

Description

Polishing drill
Technical field
The present invention relates to technical field of medical instruments, particularly a kind of polishing drill.
Background technology
In prior art, when carrying out through-hole wall polishing and orifice chamfer operation, generally need first use polishing drill to through-hole wall polishing, re-use rose reamer respectively to two orifice chamfers, in this course, except needs are changed cutter, also need workpiece to turn 180 °, to facilitate chamfering.This processing mode is not only wasted time and energy, and machining accuracy is very low.
Summary of the invention
The deficiency existing for above-mentioned prior art, the object of this invention is to provide a kind of polishing drill, and for the processing of sealing ring, one-shot forming, has improved the fineness of sealing ring, makes sealing ring have better sealing, and welding blade, provides cost savings simultaneously.
For solving the problems of the technologies described above, the technical solution used in the present invention is as follows: polishing drill, comprise handle of a knife, described handle of a knife is connected with blank matrix by the face of dodging, and described blank matrix front end is welded with blade, in described blank matrix, is provided with straight trough, in described straight trough, be provided with blade, described blade is provided with cutter head, and described blade and described cutter head are one-body molded, on described blade, are connected with arc-shaped transitional surface.
As preferably, described blade and cutter head are all positioned at the front end of described blank matrix.
As preferably, described in dodge face diameter be less than the diameter of described handle of a knife.
As preferably, the diameter of described blank matrix is greater than the diameter of described handle of a knife.
Beneficial effect of the present invention: the present invention is for the processing of sealing ring, one-shot forming, has improved the fineness of sealing ring, makes sealing ring have better sealing, and welding blade, provides cost savings simultaneously.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
The specific embodiment
For technological means, creation characteristic that the present invention is realized, reach object and effect is easy to understand, below in conjunction with the specific embodiment, further set forth the present invention.
With reference to Fig. 1, this specific embodiment is by the following technical solutions: polishing drill, comprise handle of a knife 1, described handle of a knife 1 is connected with blank matrix 3 by the face of dodging 2, and described blank matrix 3 front ends are welded with blade 4, in described blank matrix 3, are provided with straight trough 8, in described straight trough 8, be provided with blade 5, described blade 5 is provided with cutter head 6, and described blade 5 is one-body molded with described cutter head 6, on described blade 4, is connected with arc-shaped transitional surface 7.
It should be noted that described blade 5 and cutter head 6 are all positioned at the front end of described blank matrix 3.
The diameter of dodging face 2 described in it should be noted that is less than the diameter of described handle of a knife 1.
In addition, the diameter of described blank matrix 3 is greater than the diameter of described handle of a knife 1.
This concrete processing of implementing for sealing ring, one-shot forming, has improved the fineness of sealing ring, makes sealing ring have better sealing, and welding blade, provides cost savings simultaneously.
The above is only better embodiment of the present invention, and the equivalence of doing according to structure, feature and principle described in patent claim of the present invention therefore all changes or modifies, and is included in patent claim of the present invention.
