Abstract
The utility model provides a combined hole boring cutter rod which comprises an upper portion, a middle portion and a lower portion. A first cutter blade used for fine boring or large hole boring and a second cutter blade used for rough boring or small hole boring are arranged on the right side of the middle portion and the right side of the lower portion respectively, the first cutter blade is of a rhombus shape, the second cutter blade is of a triangular shape, the diameter of the middle portion is 22mm, and the diameter of the lower portion is 20mm. The combined hole boring cutter rod is simple in structure, the first cutter blade can carry out the fine boring or the hole boring, the second cutter blade can carry out the rough boring or the small hole boring, and time for changing cutters is saved.
Description
Technical field
The utility model relates to the cutting-tool engineering field, relates in particular to a kind of compound hole boring cutter rod.
Background technology
Compound hole boring cutter rod is used very extensive in machining, still, existing compound hole boring cutter rod can not disposablely carry out roughing and fine finishining at present, need to carry out tool changing, increases workload.
The utility model content
The technical problem that (one) will solve
Problem to be solved in the utility model provides a kind of compound hole boring cutter rod, and compound hole boring cutter rod can not disposablely carry out roughing and fine finishining in the prior art to overcome, and need to carry out tool changing, increases the defective of workload.
(2) technical scheme
For solveing the technical problem, the utility model provides a kind of compound hole boring cutter rod, and described knife bar comprises the upper, middle and lower; The right side of described middle part and bottom is respectively arranged with for the first blade of right boring or boring macropore and is used for heavy boring or the second blade of boring aperture; Described the first blade be shaped as rhombus; Described the second blade be shaped as triangle; Described middle part diameter is 22mm, and described lower diameter is 20mm.
Further, described lower left side also is provided with the 3rd blade, and described the 3rd blade shapes is triangle.
(3) beneficial effect
Compound hole boring cutter rod of the present utility model, simple in structure, the first blade can right boring or boring macropore, and the second blade can heavy boring or boring aperture, saves tool change time.
Description of drawings
Fig. 1 is the structural representation of a kind of compound hole boring cutter rod of the utility model.
Among the figure, 1 is top, and 2 is the first blade, and 3 is the second blade, and 4 is the middle part, and 5 is the bottom, and 6 is the 3rd blade.
The specific embodiment
Below in conjunction with drawings and Examples, the specific embodiment of the present utility model is described in further detail.Following examples are used for explanation the utility model, but are not used for limiting scope of the present utility model.
As shown in Figure 1, a kind of compound hole boring cutter rod of the present utility model, described knife bar comprises top 1, middle part 4 and bottom 5; The right side of described middle part 4 and bottom 5 is respectively arranged with for the first blade 2 of right boring or boring macropore and is used for heavy boring or the second blade 3 of boring aperture; Described the first blade 2 be shaped as rhombus; Described the second blade 3 be shaped as triangle; Described middle part 4 diameters are 22mm, and described bottom 5 diameters are 20mm.
5 left sides, described bottom also are provided with the 3rd blade 6, and described the 3rd blade 6 is shaped as triangle.The 3rd blade 6 can play the effect of tool changing, when the second blade 3 can not use, the 3rd blade 6 can be used for processing and use.
Described the first blade 2 points of a knife expose than described the second blade 3 expose many.
Add man-hour for a hole, rough bore and right boring hole can process at one time, and save tool change time, and the second blade 3 carries out heavy boring, and the first blade 2 carries out right boring.For the man-hour that adds in two holes, can be first with the second blade 3 boring apertures, the first blade 2 boring macropores save tool change time equally.
Compound hole boring cutter rod of the present utility model, simple in structure, the first blade can right boring or boring macropore, and the second blade can heavy boring or boring aperture, saves tool change time.
In sum, above-mentioned embodiment is not to be restricted embodiment of the present utility model, and the modification that all those skilled in the art carry out on the basis of flesh and blood of the present utility model or equivalent deformation are all at technology category of the present utility model.
