Description
Technical field
This utility model relates to a kind of dedicated tool for gas bottle hole machined in the mouth.
Background technology
At present, gas cylinder, as the storage facilities of gas medium, is all widely used in all kinds of fields.The quality of gas cylinder bottle neck is straight
Connect the air-tightness affecting gas cylinder.In existing processing method, work step is more, relatively complicated, first passes through tapering bit bore,
Inner Hole chamfering, conventional drill bit are bored, after boring also by recycling lathe tool by fluted drill, chit drill, centre drill, depth drill, tapering
Needing to carry out chamfering, operation complexity, therefore, it is urgently to be resolved hurrily for developing a kind of dedicated tool for gas bottle hole machined in the mouth
New problem.
Summary of the invention
The purpose of this utility model is to provide a kind of simple in construction, the easy to operate special cutter for gas bottle hole machined in the mouth
Tool.
The technical solution adopted in the utility model is: a kind of gas bottle hole machined dedicated tool in the mouth, by drill bit, main body and handle of a knife
Constitute；Main body one end connects drill bit, and the other end connects handle of a knife, and reaming blade is located in main body, connects end in main body and handle of a knife,
The root of reaming blade is provided with chamfered cutting edge.
Above-mentioned gas bottle hole machined dedicated tool in the mouth, drill bit, main body and handle of a knife are formed integrally structure.
Above-mentioned gas bottle hole machined dedicated tool in the mouth, described drill bit 1 is taper.
Above-mentioned gas bottle hole machined dedicated tool in the mouth, described main body is taper, and tapering is 6.87 °.
Above-mentioned gas bottle hole machined dedicated tool in the mouth, described reaming blade is arranged along the outer rim spiral of main body.
Above-mentioned gas bottle hole machined dedicated tool in the mouth, described chamfered cutting edge is arranged along the upper end outer rim of handle of a knife.
Above-mentioned gas bottle hole machined dedicated tool in the mouth, described chamfered cutting edge is at 45 ° with handle of a knife.
The beneficial effects of the utility model are: this utility model is provided with chamfered cutting edge at the root of reaming blade so that reaming and
Chamfering once completes, and is greatly saved process time, cost-effective, and efficiency is high, easily operates.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
As it is shown in figure 1, a kind of gas bottle hole machined dedicated tool in the mouth, it is made up of drill bit 1, main body 2 and handle of a knife 3.Drill bit
1, main body 2 and handle of a knife 3 are formed integrally structure
Drill bit 1 is arranged on the end of main body 2, makes taper, for gas bottle hole drilling in the mouth.
Being provided with reaming blade 4 in the outer rim of main body 2, described reaming blade 4 is arranged along the outer rim spiral of main body 2.For
The reaming in gas bottle hole in the mouth.Described main body 2 makes taper, and tapering a is 6.87 °.
Handle of a knife 3 is connected with main body 1, connects end in main body 2 and handle of a knife 3, and the root of reaming blade 4 is provided with chamfered cutting edge 5.
That is, described chamfered cutting edge 5 is arranged along the upper end outer rim of handle of a knife 3.Described chamfered cutting edge 5 axially becomes 45 with handle of a knife 3
°.Chamfered cutting edge 5 is for gas bottle Hole chamfering in the mouth.
