Description
Technical field
A kind of compound coarse-fine boring chamfering tool of the utility model, belongs to process tool technical field.
Background technique
Commonly used cutter when boring cutter is hole machined, it is corresponding for carrying out roughing and finishing to existing hole
Boring cutter is divided into rough boring cutter and fine boring cutter.The general processing method of boring cutter is exemplified below, SC87 cabinet is engineering machinery stirring
Box body of speed reducer on machine transmission parts, two side faces hole require φ 180+0.03/0, Ra=1.6 μm, since the aperture in this hole requires
Higher, it is finally chamfering that common processing method, which carries out right boring to reserve allowance for finish after heavy boring, and this method is operation letter
Single, overall situation abrasion is relatively fewer, but working efficiency is low, is also easy to produce waste product, so existing cutter needs improve.
Utility model content
The utility model overcomes the shortcomings of the prior art, technical problem to be solved be provide it is a kind of by heavy boring,
The compound coarse-fine boring chamfering tool that right boring and chamfering are completed during time processing.
In order to solve the above-mentioned technical problem, a kind of the technical solution adopted in the utility model are as follows: compound coarse-fine boring rose reamer
Tool, including cutter hub, heavy boring portion, right boring portion and chamfering blade, described cutter hub one end are knife handle, and the other end is blade fixed part, institute
The section for stating blade fixed part is rectangle, and blade fixed part is fixedly arranged at the front end with heavy boring portion and right boring portion, after blade fixed part
End has symmetrical two boss, is respectively fixed with a chamfering blade on two boss；
The structure in the heavy boring portion are as follows: heavy boring blade is weldingly fixed on heavy boring blade bearing by screw or copper, rough boring cutter
Bar is fixed by screws on blade fixed part；
The structure in the right boring portion are as follows: right boring blade is weldingly fixed on right boring blade bearing by screw or copper, fine boring cutter
Bar is fixed by screws on blade fixed part；
The heavy boring blade is located at the front of right boring blade, and the distance of heavy boring blade to rotation centerline is less than fine boring cutter
Distance of the piece to rotation centerline.
In the axis projection of this cutter, the line of the heavy boring blade and right boring blade passes through rotation center, two institutes
The line for stating chamfering blade also passes through rotation center, and the folder of two chamfering blade lines and heavy boring blade and right boring blade line
Angle a is 15 ° -25 °.
The utility model has the advantages that compared with prior art.
1, heavy boring blade, right boring blade and chamfering blade are integrated on a structure of the cutter body by the utility model, by heavy boring,
Right boring and chamfering three different processes are disposably completed, and the time and number, processing efficiency for reducing assembly and disassembly cutter greatly improve,
And the Product Precision processed is high, quality is stablized.
2, the section of blade fixed part is huge shape in the utility model, compares with conventional circle, reduces volume, is saved
Material.
3, heavy boring blade, right boring blade are opposite in the utility model installs, and two chamfering blades are symmetrically installed, and keep this practical
Novel entirety reasonable stress, it is high in machining efficiency.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Fig. 2 is the right view of Fig. 1.
In figure: 1 is cutter hub, and 11 be knife handle, and 12 be blade fixed part, and 2 be heavy boring portion, and 21 be heavy boring blade, and 22 be heavy boring
Blade bearing, 3 be right boring portion, and 31 be right boring blade, and 32 be right boring blade bearing, and 4 be chamfering blade, and 5 be boss.
Specific embodiment
The utility model is described in more detail with reference to the accompanying drawing.
As Figure 1-Figure 2, a kind of compound coarse-fine boring chamfering tool of the utility model, including cutter hub 1, heavy boring portion 2, right boring
Portion 3 and chamfering blade 4, described 1 one end of cutter hub are knife handle 11, and the other end is blade fixed part 12, the blade fixed part 12
Section is rectangle, and blade fixed part 12 is fixedly arranged at the front end with heavy boring portion 2 and right boring portion 3, and the rear end of blade fixed part 12 has pair
Two boss 5 claimed are respectively fixed with a chamfering blade 4 on two boss 5；
The structure in the heavy boring portion 2 are as follows: heavy boring blade 21 is weldingly fixed on heavy boring blade bearing 22 by screw or copper, slightly
Boring cutter bar 22 is fixed by screws on blade fixed part 12；
The structure in the right boring portion 3 are as follows: right boring blade 31 is weldingly fixed on right boring blade bearing 32 by screw or copper, essence
