Description
Technical field
This utility model relates to machine tool technical field, particularly relates to a kind of stepped hole polish composite boring cutters.
Background technology
In the existing course of processing, the hole surface that drill bit bores is the most coarse, and deflection the most easily occurs in the axis in hole, reaches not
To using requirement, need to carry out polish finishing, make the surface in hole reach to use requirement.Bore hole is that one carries out polish to hole
Conventional manufacturing process, can be effectively improved the precision in hole, reduce the surface roughness in hole, and the axis of correction hole.
On existing workpiece, usually there will be stepped hole, stepped hole is big due to the diameter of two step parts of himself
Little differing, when bore hole, need to carry out at twice bore hole finishing, working (machining) efficiency is relatively low, hole axiality the most bad.This practicality
Novel provide a kind of composite boring cutters for stepped hole polish, can once complete the bore hole operation of stepped hole, working (machining) efficiency
Height, the precision in the hole of processing is high.
Utility model content
The technical problems to be solved in the utility model is: provides a kind of stepped hole polish composite boring cutters, can once complete
The bore hole operation of stepped hole, working (machining) efficiency is high, and the surface roughness of processing hole stepped hole is low, and axiality is good.
In order to solve described technical problem, the technical solution of the utility model: a kind of stepped hole polish composite boring cutters, bag
Including matrix, matrix includes the first bore hole portion and the second bore hole portion that connecting portion and processing department, described processing department include being coaxially disposed,
The diameter of end and the second bore hole portion that the second bore hole portion that is formed at is protruded in described first bore hole portion is more than the straight of the first bore hole portion
, there are the most L-shaped the first cutting slot of the cross section of symmetry and the second cutting slot, institute in footpath along matrix axially arranged in processing department
State the first cutting slot and the second cutting slot and extended to the medium position in the second bore hole portion by the end in the first bore hole portion, first
Cutting slot is provided with the first boring cutter and the second boring cutter, is provided with the 3rd boring cutter and the 4th boring cutter on the second cutting slot.
As preferably, described connecting portion is provided with along the axially arranged locating surface of matrix.
Compared with prior art, this utility model uses said structure, can complete stepped hole by a bore hole operation
Surface Finishing, working (machining) efficiency is high, and the finished product accuracy after processing is high, and surface roughness is low, and axiality is good.

Detailed description of the invention
Below by combining the drawings and specific embodiments, the technical solution of the utility model is described in further detail.
Seeing in figure, the composite boring cutters of a kind of stepped hole polish that this utility model provides, including matrix, matrix includes even
Connecing portion 1 and processing department, connecting portion 1 and processing department are coaxially disposed and one-body molded, and the diameter of processing department is greater than the straight of connecting portion 1
Footpath.Processing department is provided with two bore hole portions, the respectively first bore hole portion 3 and the second bore hole portion 2, adds man-hour, can be disposably to platform
Two step surfaces in hole, rank carry out Boring, and working (machining) efficiency is high, and owing to the first bore hole portion 3 and the second bore hole portion 2 are respectively provided with
In processing department, they are inherently coaxially disposed so that this composite boring cutters step when being processed stepped hole, after processing
Hole axiality is good.
The diameter in the first bore hole portion 3 is greater than the diameter in the second bore hole portion 2, and the first bore hole portion 3 protrudes and is formed at the second boring
The end in hole portion 2 so that form a step surface 8 between the first bore hole portion 3 and the second bore hole portion 2.Processing department is provided with
One cutting slot 5 and the second cutting slot 5a, the first cutting slot 5 and the second cutting slot 5a is extended by the end in the first bore hole portion 3 always
To the medium position in the second bore hole portion 2, the cross section of the first cutting slot 5 and the second cutting slot 5a is the most L-shaped, wherein, and width
Bigger one side is clearance surface 52, and the one side that width is less is cutting face 51.The cutting face 51 of the first cutting slot 5 is provided with
One boring cutter 7 and the second boring cutter 6, the first boring cutter 7 is positioned at the end in the first bore hole portion 3, and the blade of the first boring cutter 7 protrudes the first boring
The seamed edge in hole portion 3；Second boring cutter 6 is positioned at the first bore hole portion 3 and intersection in the second bore hole portion 2, and the blade of the second boring cutter 6 is convex
Go out the seamed edge between step surface 8 and the second bore hole portion 2.The cutting face 51 of the second cutting slot 5a is provided with the 3rd boring cutter 10 and
Four boring cutters 9, the 3rd boring cutter 10 is symmetricly set on the end in the first bore hole portion 3 with the first boring cutter 7 on the basis of the axis of matrix, the
Four boring cutters 9 are symmetricly set on the first bore hole portion 3 and connection in the second bore hole portion 2 on the basis of the axis of matrix with the second boring cutter 6
Place.First boring cutter 7, the second boring cutter 6, the 3rd boring cutter 10 and the 4th boring cutter 9 are all arranged on respective installation by attachment screw 11
