Description
Technical field
This utility model belongs to tooling cost field, is specifically related to a kind of superhard cutter that can change cutter head by hand.
Background technology
In recent years, along with the fast development of Computerized Numerical Control processing technology and commonly using of Digit Control Machine Tool, high efficiency can be realized, high stability, the superhard cutter of long-life processing are day by day popularized.The form of superhard cutter can be largely classified into overall glomerocryst cutter and brazed shank tool at present.The cost of overall glomerocryst cutter is high, and cannot beat hole, location on polycrystal, it is difficult to adapts to high accuracy processing request, is developed superhard brazed shank tool for this.
Superhard brazed shank tool mainly has two kinds of modes of production, and one is that through High Temperature High Pressure, diamond is made composite sheet with cubic boron nitride together with hard alloy, then composite sheet is soldered on hard alloy substrate；Another kind is polycrystalline diamond and polycrystalline cubic boron nitride to be soldered directly on hard alloy substrate.These two kinds of methods are cutter head and are directly welded on hard alloy substrate, and therefore after tool bit abrasion lost efficacy, this blade is inefficacy.And due to welded existence, the glomerocryst cutter head of its abrasion and hard alloy substrate then become garbage.Although each enterprise is proposed the brazed shank tool of many cutting edges, such as patent CN204893005, CN202701422 etc., its both is to use cutter head to be welded with matrix, and after the cutting edge of cutter head lost efficacy, cutter head i.e. lost efficacy, and cutting edge is few simultaneously.
Summary of the invention
The purpose of this utility model is to provide a kind of superhard cutter that can change cutter head by hand.
Based on above-mentioned purpose, this utility model adopts the following technical scheme that: a kind of superhard cutter that can change cutter head by hand, and including matrix and cutter head, described matrix is provided with the mounting groove matched with cutter head, and described cutter head is fixed on matrix by securing member.
Matrix is provided with the mounting groove matched with cutter head, and the both sides of mounting groove are provided with installing hole, and cutter head is fixed on matrix by the fastening nail being provided with in installing hole.
Described matrix is circular base or polygon matrix.
Described matrix is square matrix or rhombus matrix or triangle matrix.
Described matrix is rhombus matrix, and rhombus matrix is made up of two symmetrical base units, and rhombus matrix is provided with the through hole connecting two base units, is provided with attachment screw in through hole；The mounting groove matched with cutter head is positioned at the end that two base units are connected.
The center of described matrix is provided with hole, location.
It is provided with clamping part in the middle of the both sides of described cutter head, clamping part is planar structure, and the connecting portion between clamping part and the two ends of cutter head is arcwall face, and the two ends of cutter head are provided with blade, the side of the upper and lower end face of blade is provided with cutting edge, is formed with space between cutting edge and matrix.
The outline of described cutter head is dumbbell shaped, and the two ends of cutter head are V-shaped.
Described cutter head is PCD cutter head or PCBN cutter head, and matrix is hard alloy substrate.
Compared with prior art, technique effect of the present utility model particularly as follows:
1) this utility model can realize cutter head by the way of using and installing screwed hole and trip bolt and is convenient for changing, and efficiently solving after superhard brazed shank tool lost efficacy cannot the problem of recycling；The utilization rate of cutter head can be increased simultaneously, two original cutting edges become four present cutting edges；
2) matrix uses the form of base unit combination, it is achieved while being easy to the installation of matrix, it is possible to increase the adhesion between matrix and cutter head further；
3) use the laminating Du Genggao of cutter head of the present utility model and matrix, coordinate tightr.

Fig. 1 is structural representation of the present utility model；
Fig. 2 is the structural representation of cutter head in this utility model;
Fig. 3 is the enlarged diagram in Fig. 1 at A.
Detailed description of the invention
A kind of superhard cutter that can change cutter head by hand as shown in Figure 1,2 and 3, including hard alloy substrate 1 and PCD cutter head or PCBN cutter head 2, matrix 1 center is provided with hole 14, location, matrix 1 is provided with the mounting groove matched with cutter head 2, the both sides of mounting groove are provided with installation screwed hole 12, and cutter head 2 is fixed on matrix 1 by the trip bolt being provided with in installing screwed hole 12；Matrix 1 is rhombus matrix, and rhombus matrix is made up of two symmetrical base units 11, and rhombus matrix is provided with the through hole 13 connecting two base units, is provided with attachment screw in through hole 13；The mounting groove matched with cutter head 2 is positioned at the end that two base units are connected.
The outline of cutter head 2 is dumbbell shaped, and the longitudinal section at cutter head 2 two ends is V-shaped.Clamping part 23 it is provided with in the middle of the both sides of cutter head 2, clamping part 23 is planar structure, connecting portion 24 between the two ends of clamping part 23 and cutter head 2 is arcwall face, the two ends of cutter head 2 are provided with blade 21, the side of the upper and lower end face of blade 21 is provided with cutting edge 22, it is formed with space 3 between cutting edge 22 and matrix 1, it is ensured that the cutting edge of cutter head is intact in cutter head work process, will not be damaged.
During assembling, first matrix 1 is clamped cutter head 2, tighten attachment screw and cutter is integrally forming, then regulate trip bolt to regulate the clamping force of cutter head 2.
When a cutting edge wear out failure of cutter head 2, screw can be unclamped, change the cutting edge of cutter head 2, it is achieved a cutter head can be reused for four times, when four equal wear out failures of cutting edge of a cutter head, replaceable next cutter head, it is achieved the replacing of cutter head.
It is pointed out that the rhombus matrix that the shape of matrix is not limited in the present embodiment, in other embodiments, matrix can also select circular base or the polygon matrix such as square matrix, triangle matrix.
