Abstract
The utility model discloses a forming thick boring cutter used for machining of engine oil holes. The forming thick boring cutter comprises a cutter bit and a cutter handle. A Morse cone is adopted for the cutter handle. A threaded through hole is formed inside the cutter handle. The cutter bit is composed of five cutting sections which are a first cutting section, a second cutting section, a third cutting section, a fourth cutting section and a fifth cutting section. The tail portion of a last stage cutting section is connected with the head portion of a next stage cutting edge section. The tail portion of the fifth cutting section is connected with the cutter handle. The forming thick boring cutter overcomes the defects that in the prior art, a forming thick boring cutter with a plurality of cutting sections is adopted, each section of cutting edge is provided with one blade, machining speed is slow, and a blade arranged in a concave table is not stable. The forming thick boring cutter is improved. Each cutting section is provided with two blades so that coaxiality is ensured, machining efficiency is improved, and machining time is saved.
Description
Technical field
The utility model belongs to the cutter of machining, particularly a kind of moulding heavy boring cutter.
Background technology
Existing boring cutter generally adopts multistage cutting segmentation, though it has changed the working (machining) efficiency of former single hop boring cutter, but has only a cutting edge on every grade of cutting edge section of multistage multi-tool edge boring cutter, working (machining) efficiency is still too low, and the concave station place smoother of boring cutter, the blade of installation is subjected to force unbalance when cutting, cause blade to move easily, influence processing effect.
The utility model content
Technical problem to be solved in the utility model provides a kind of moulding heavy boring cutter, can solve that multistage multi-tool edge boring cutter working (machining) efficiency is low, concave station installs the blade problem of unstable.
In order to solve the problems of the technologies described above, the utility model provides following technical scheme: a kind of moulding heavy boring cutter, comprise cutter head and handle of a knife, described handle of a knife adopts Morse's cone, inside offers tapped through hole, and described cutter head adopts five sections segment of cutting, is made of first segment of cutting, second segment of cutting, the 3rd segment of cutting, the 4th segment of cutting and the 5th segment of cutting, the afterbody of upper level segment of cutting is connected with the head of next stage level cutting edge section, and the afterbody of the 5th segment of cutting is connected with handle of a knife; The head of described each segment of cutting has concave station, equal counteredge in the concave station, and the head of described each segment of cutting all is symmetrically distributed with two concave stations, and described concave station place is provided with matsurface.
Before the processing, install cutting blade and chamfered cutting edge according to the processing needs, then handle of a knife is connected by bolt with lathe, can process.
Advantage: 1, every section cutting edge of boring cutter has two blades, has improved process velocity; 2, the concave station place is provided with matsurface, is convenient to promote soundness between blade and the concave station.
Description of drawings
Fig. 1 is the utility model structural representation;
Fig. 2 is the schematic diagram (one of them concave station is not drawn blade) at the utility model concave station place.
The specific embodiment
Shown in Fig. 1, Fig. 2, the utility model is a kind of moulding heavy boring cutter, comprise cutter head 1 and handle of a knife 2, described handle of a knife 2 adopts Morse's cone, inside offers tapped through hole 10, and described cutter head 1 adopts five sections segment of cutting, is made of first segment of cutting 5, second segment of cutting 6, the 3rd segment of cutting 7, the 4th segment of cutting 8 and the 5th segment of cutting 9, the afterbody of upper level segment of cutting is connected with the head of next stage level cutting edge section, and the afterbody of the 5th segment of cutting 9 is connected with handle of a knife; The head of described each segment of cutting has concave station 3, equal counteredge 4 in the concave station 3, and the head of described every grade of cutting edge section all is symmetrically distributed with two concave stations 3, and concave station 3 places are provided with matsurface 11, and matsurface 11 can increase blade 4 and concave station 3 soundness.Wherein Fig. 1 is simplified painting, though only drawn two blades of first segment of cutting, second, third, the 4th, the 5th segment of cutting all only drawn a blade, in every section actual enforcement of segment of cutting two blades can be installed all.
Before the processing, at first segment of cutting 5, second segment of cutting 6 and the 4th segment of cutting 8 cutting blade is installed according to the processing needs; At the 3rd segment of cutting 7 and the 5th segment of cutting 9 chamfered cutting edge is installed, the angle of the chamfered cutting edge of its installation and cutter hub outer end side is 30 °, then handle of a knife is connected by bolt with lathe, can process.
Before the processing, blade 4 is installed to successively on the concave station 3 of each segment of cutting, blade 4 is fixed on the concave station 3 by screw, then with handle of a knife 2 and lathe by being connected.
Add man-hour, first segment of cutting 5 touches object to be processed earlier, locatees, and begins to expand the hole of dark 9mm, diameter 7mm then;
Continue feeding, second segment of cutting 6 begins to expand the hole that dark 10mm, diameter 8mm;
Continue feeding, the 3rd segment of cutting 7 is poured out 30 ° of angles;
Continue feeding, the 4th segment of cutting 8 expands and dark 10mm, diameter 9mm;
Continue feeding, the 5th segment of cutting 9 intact chamferings at 45.
Expand diameter, the degree of depth and the chamfering of portalling and settle at one go, machine.
Above-described only is preferred embodiment of the present utility model; should be understood that; for a person skilled in the art; under the prerequisite that does not break away from the utility model structure; can also make some distortion and improvement; these also should be considered as protection domain of the present utility model, and these can not influence effect and practical applicability that the utility model is implemented.
