In addition, adopt conventional reamers to carry out the deep hole of working fluid pressure valve block, add cutter poor stability in man-hour, working (machining) efficiency is low, cutting speed 5 ~ 8 ms/min, and cutting-tool's used life is low, causes processing percent defective high, takes time and effort.
Utility model content
The technical problem that the utility model mainly solves be to provide a kind ofly can slightly to cut with scissors simultaneously, partly finish ream and finish ream, hydraulic valve block deep hole machining reamer efficiently.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: provide a kind of hydraulic valve block deep hole machining reamer, comprise: supporting rod and reamer bar, described supporting rod is connected setting with one heart with reamer bar, described supporting rod and reamer bar center are provided with through cooling water hole, described reamer bar is provided with the second reamer head, described reamer bar end correspondence is provided with the first reamer head with the second reamer head concentric, described first reamer head comprise six not decile tooth distribution the first cutting edge, described second reamer head comprise six not decile tooth distribution the second cutting edge, described first cutting edge side is respectively arranged with the apopore be connected with cooling water hole.
In the utility model preferred embodiment, the diameter of described first reamer head makes both arrange in ladder than the little 0.1mm of the diameter of the second reamer head.
In the utility model preferred embodiment, the distal opening place that described cooling water hole is positioned at the first reamer head is provided with capping.
In the utility model preferred embodiment, between described first reamer head and the second reamer head, be provided with cannelure.
In the utility model preferred embodiment, described supporting rod diameter is greater than reamer bar diameter, and described hydraulic valve block deep hole machining reamer overall length is less than 330mm.
The beneficial effects of the utility model are: a kind of hydraulic valve block deep hole machining reamer that the utility model is pointed out, first reamer head carries out thick hinge and partly finish reams, and then the second reamer head finish reams, working (machining) efficiency is high, large surplus processing can be carried out, improve fine finishining quality, dispersion cooling, cooling and chip removal effective, six swords not decile tooth distribution technique reduce the vibration of reamer under high speed operation environment, can ensure that cutter is processed in higher cutting speed (>50 m/min), working (machining) efficiency is more than 10 times of conventional reamers, hole roughness can ensure in Ra0.4 ~ 0.6, hole cylindricity reaches 0.003 millimeter, high life, 3000 holes can be processed.
Accompanying drawing explanation
In order to be illustrated more clearly in the technical scheme in the utility model embodiment, below the accompanying drawing used required in describing embodiment is briefly described, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings, wherein:
Fig. 1 is the structural representation of a kind of hydraulic valve block deep hole machining of the utility model reamer one preferred embodiment;
Fig. 2 is the part A enlarged drawing in Fig. 1;
Fig. 3 is that enlarged drawing is looked on the left side in Fig. 1.
Detailed description of the invention
Be clearly and completely described to the technical scheme in the utility model embodiment below, obviously, described embodiment is only a part of embodiment of the present utility model, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making other embodiments all obtained under creative work prerequisite, all belong to the scope of the utility model protection.
Refer to Fig. 1 to Fig. 3, the utility model embodiment comprises:
A kind of hydraulic valve block deep hole machining reamer, comprise: supporting rod 1 and reamer bar 2, described supporting rod 1 is connected setting with one heart with reamer bar 2, described supporting rod 1 and reamer bar 2 center are provided with through cooling water hole 3, described reamer bar 2 is provided with the second reamer head 22, described reamer bar 2 end correspondence is provided with the first reamer head 21 with the second reamer head 22 concentric, described first reamer head 21 comprise six not decile tooth distribution the first cutting edge, described second reamer head 22 comprise six not decile tooth distribution the second cutting edge, six swords not decile tooth distribution technique reduce the vibration of reamer under high speed operation environment, can ensure that cutter is processed in higher cutting speed (>50 m/min), the diameter of described first reamer head 21 makes both arrange in ladder than the little 0.1mm of the diameter of the second reamer head.
Add man-hour first reamer head 21 carry out thick hinge and partly finish ream, and then the second reamer head 22 finish reams, and working (machining) efficiency is high, and the first reamer head 21 and the second reamer head 22 adopt atomic particle carbide alloy material to make, super wear-resisting.
