Description
Technical Field
The utility model relates to a drilling reamer, especially a drilling reamer of long-life high accuracy.
Background
A high precision hole typically undergoes three manufacturing operations: the drilling reamer comprises a drill (cutting), a rough reaming tool and a finish reaming tool, wherein a cutting edge, a rough reaming edge and a finish reaming edge of a common drilling reamer are arranged on the same blade and are connected, so that the grinding use times are few after the cutting edge is worn, the service life is short, and the drilling reamer which can ensure the processing precision, increase the grinding use times and prolong the service life is designed aiming at the problems.
Disclosure of Invention
In order to overcome the defects of the prior art, the utility model provides a drilling reamer with long service life and high precision.
The utility model provides a technical scheme that its technical problem adopted is:
the utility model provides a long-life high accuracy drilling reamer, includes tool bit and guide arm, be equipped with cutting edge, its characterized in that on the tool bit: the tool bit is also provided with a first chip groove, a second chip groove, a coarse reamer and a fine reamer, the cutting edge is connected with the coarse reamer, and the cutting edge is formed by intersecting a chip front tool face and a chip rear tool face; the fine reaming blade is formed by intersecting a fine reaming front blade surface and a fine reaming rear blade surface; the rough reaming edge is formed by intersecting a rough reaming front cutter face and a rough reaming rear cutter face, the cutting front cutter face and the finish reaming front cutter face are side wall faces of the first chip discharge grooves, the finish reaming front cutter face is a side avoiding face of the second chip discharge grooves, a grinding face is arranged on the cutter head, and the grinding face is intersected with the finish reaming front cutter face and the finish reaming rear cutter face.
The fine reaming rear cutter face is an arc-shaped face.
The rear cutter face of the coarse hinge is an arc-shaped face.
Four fine reamer blades, two cutting blades and two coarse reamer blades are arranged on the cutter head.
The utility model has the advantages that: the fine reamer and the coarse reamer are separately arranged, so that the number of the fine reamer and the number of the coarse reamer can be respectively set, the optimal number ratio of the fine reamer and the coarse reamer can be ensured, and the reaming effect can be better achieved; the fine reaming edge and the coarse reaming edge can be made very long; and the finish reamer, the cutting edge and the rough reamer are polished together through the polishing surface, so that the polishing times are improved, and the purpose of prolonging the practical service life is achieved.
Drawings
The present invention will be further explained with reference to the drawings and examples.
Fig. 1 is a front view of the present invention;
fig. 2 is a side view of the present invention;
fig. 3 is a perspective view of the present invention.
Detailed Description
Referring to fig. 1 to 3, the utility model discloses a long-life high-precision drilling reamer, including tool bit and guide arm 1, be equipped with two cutting edges 2 on the tool bit, still be equipped with chip groove one 3, chip groove two 4, two thick reamer blades 5 and four finish reamer blades 6 on the tool bit, cutting edge 2 meets with thick reamer blade 5, two cutting edges 2 set up relatively among the above-mentioned, are equipped with finish reamer blade 6 between cutting edge 2, four finish reamer blades 6 set up two by two relatively, chip groove one 3 is located cutting edge 2 and finish reamer blade 6, because the chip yield is big, chip groove one 3 is darker and wider; four chip discharge grooves two 4 are formed, two of the four chip discharge grooves are formed between the fine reaming edges 6, the other two chip discharge grooves are formed between the fine reaming edges 6 and the cutting edges 2, and the chip discharge grooves two 4 are shallow and narrow due to small chip discharge.
As shown in the figure, the cutting edge 2 is formed by intersecting a chip rake face 7 and a chip relief face 8; the fine reaming edge 6 is formed by intersecting a fine reaming front cutter face and a fine reaming rear cutter face 12; coarse reamer blade 5 comprises the crossing constitution of coarse reamer rake face 9 and coarse reamer back knife face 10, smear metal rake face 7 and finish reamer rake face are the lateral wall face of chip groove one 3, the finish reamer rake face is the side face of keeping away of chip groove two 4, be equipped with on the tool bit and dodge the breach, should dodge the breach and include two walls, and one of them is the face of repairing grinding 11, and this face of repairing grinding 11 and finish reamer rake face and finish reamer back knife face 12 are all crossing, through dodging the breach we not only can repair the damaged finish reamer blade 6 of wearing off, and through should dodging the breach we can guarantee that coarse reamer blade 5 is thick the hinge earlier, then finish reamer blade 6 moves down the finish reamer again, guarantees the reaming quality, and the coping of cutting edge 2 and coarse reamer blade 5 is conventional mode, therefore does not give details.
In the above-mentioned structure, finish reamer 6 and thick reamer 5 are located different circumference positions, therefore finish reamer 6 all can do very long with thick reamer 5, therefore can the greatly increased coping number of times, and like this we can be according to finish reamer 6 and thick reamer 5 the proportion setting for two to one, better reach the reaming effect to the smooth finish quality in hole has been improved.
The rough reaming rear cutter face 10 is an arc-shaped face, and the rough reaming rear cutter face 10 forms an arc-shaped cutting edge, so that the hole wall can be extruded to play a role in improving the smoothness; the finish reaming rear cutter face 12 is an arc-shaped face, and the finish reaming rear cutter face 12 forms an arc-shaped cutting edge, so that the hole wall can be extruded to play a role in improving the smoothness.
The above detailed description is made on the drilling reamer with long service life and high precision provided by the embodiment of the present invention, and the detailed examples are applied herein to explain the principle and the implementation manner of the present invention, and the description of the above embodiments is only used to help understand the method and the core idea of the present invention; meanwhile, for the general technical personnel in the field, according to the idea of the present invention, there are changes in the specific implementation and application scope, to sum up, the content of the present specification should not be understood as the limitation of the present invention.
