Detailed description of the invention
Below in conjunction with the accompanying drawings and the specific embodiments the utility model is described in further detail.
As shown in Figure 1, a kind of segmented reamer, comprises drillstock 1, drilling rod 2 and the reaming cutter 3 in flat square structure, and described drillstock 1 is away from the tang formula of tail end 11 in No. 6, the Morse's taper corresponding with tail stock tapering of drilling rod 2; Adopt large cutting output, three stage structure, the quick cutting of many stepped holes and deep hole is carried out by the drilling rod 2 of quick-replaceable different-diameter, length and reaming cutter 3, save plenty of time, cost of labor, and owing to have employed segmentation structure, quick-replaceable reaming cutter 3 moiety by weight is light, and machine mill, manual mill are all accurately more convenient.
Continue with reference to Fig. 1, described reaming cutter 3 is welded with the blade 4 of two panels symmetry, and wherein said blade 4 adopts Hardmetal materials to make.Reaming cutter 3 adopts welded type blade 4, and blade 4 material can be selected according to rapidoprint, makes blade 4 more adapt to institute's converted products, reduces blade 4 and weares and teares, increase the service life; Make product to be processed precision, roughness closer to product demand; Reaming cutter 3 is in flat square structure, and in process, chip removal is convenient, makes finished surface be not easy to crush injury or produce cut; Is blade type configuration due to what adopt, blade 4 can grind chip-breaker, and chip breaking is effective and make processing safer; After blade 4 weares and teares, reaming cutter 3 can be reused by welding blade 4 again, saves cost in a large number.Described drillstock 1 and drilling rod 2, end interface between drilling rod 2 and reaming cutter 3 all adopt major diameter fine thread to connect, and the both ends interface of described drilling rod 2 is consistent with the end interface of drillstock 1 and the end interface size shape of reaming cutter 3 respectively.During processing short-bore, directly dismantled down by drilling rod 2, drillstock 1 is directly threaded with reaming cutter 3; Deep hole processing or short-bore, convert convenient, flexible, improve working (machining) efficiency.
Shown in composition graphs 1 and Fig. 2, described drilling rod 2 is provided with an inlet opening 21 connected with lathe cooler bin water pipe, one is provided with vertically from the end be connected with reaming cutter 3 to the deep and long hole 22 of inlet opening 21 in described drilling rod 2, be provided with the limbers 31 connected with deep and long hole 22 in described reaming cutter 3 vertically, and be radially provided with the apopore 32 connected with blade 4; The inlet opening 21 be interconnected, deep and long hole 22, limbers 31 and apopore 32 form built-in cooling system, this built-in cooling system can directly and fully cooling surface to be machined and blade 4 working position, reduce the various performances of thermal deformation and maintenance material, the service life of blade 4 is extended greatly.In the utility model, inlet opening 21 set on drilling rod 2 is a screwed hole.
Installation steps during the utility model deep hole processing are as follows:
1, drillstock 1 is loaded tailstock tool, now the tapering of drillstock 1 tail end 11 is just corresponding with tailstock tool;
2, drilling rod 2 is threaded with drillstock 1;
3, reaming cutter 3 is threaded with drilling rod 2;
During processing short-bore, above-mentioned installation steps 2 and step 3 are merged into: be threaded with reaming cutter 3 by drillstock 1.
Compared with prior art, the utility model has the following advantages:
1, with low cost, easy to manufacture, easy to use;
2, can by changing reaming cutter 3 or assembly and disassembly drilling rod 2 realize for the degree of depth of holing and diameter;
3, blade 4 adopts Hardmetal materials to make, and can repeat sharpening and replacing.
4, directly by the cutting fluid on lathe from built-in cooling system introducing to cutting position, cooling system need not be increased in addition, reduce cost.
The above, be only the utility model preferred embodiment, therefore can not limit with this scope that the utility model implements, the equivalence namely done according to the utility model claim and description change with modify, all should still belong in scope that the utility model patent contains.
