At present, the head of crown drill bit and drilling rod have multiple combination mode.Such as there are " pin is located, and screw runs through locking ", " broken line groove is located, positive left-hand thread screw lock ", " open pin location, non-screw rotates clamping " etc. all multi-form.

Utility model content

The purpose of this utility model is the deficiency overcoming prior art existence, provides a kind of V-arrangement to locate two screw lock crown blade.

The purpose of this utility model is achieved through the following technical solutions:

The two screw lock crown blade in V-arrangement location, feature is: the cutter blade of described crown blade removes its parallel portion by a cylinder, cutter blade has ground chip area, cutter blade right-hand member is removed V-shaped part and is formed V-arrangement angle, cutter blade left end is provided with the cutting edge be made up of chisel edge, transitional edges and main cutting edge, the intersection of chip area and rear knife face forms main cutting edge, and after two, the intersection of knife face forms chisel edge, and between main cutting edge and chisel edge, mill has transitional edges; The upper and lower face of cylinder of cutter blade grinds unnecessary part and retain a section spiral line formation seamed edge, cutter blade offers two for installing half shoulder hole of housing screw.

Further, the above-mentioned two screw lock crown blade in V-arrangement location, wherein, the angle formed between main cutting edge is drift angle, and angle is 120 ~ 140 °.

Further, the above-mentioned two screw lock crown blade in V-arrangement location, wherein, described seamed edge in the shape of a spiral.

Further, the two screw lock crown blade in above-mentioned V-arrangement location, wherein, described seamed edge in the shape of a spiral and have the face of cylinder of width.

Further, the above-mentioned two screw lock crown blade in V-arrangement location, wherein, the helical angle of described seamed edge is 15 ° ~ 30 °.

Again further, the above-mentioned two screw lock crown blade in V-arrangement location, wherein, described cutter blade right-hand member is provided with groove.

Again further, the above-mentioned two screw lock crown blade in V-arrangement location, wherein, the angle of described V-arrangement angle is 90 ~ 120 °.

The substantive distinguishing features that technical solutions of the utility model are outstanding and significant progress are mainly reflected in:

1. the utility model crown blade has V-arrangement location structure, and V-arrangement location structure is fairly simple, and production precision is easy to ensure; V-arrangement location structure contact surface is comparatively large, and positioning precision is high, and structural reliability is good;

2. crown blade has the locking mechanism of half shoulder hole, two screw lock structure, and auxiliary screw is many, and cost is low;

3. crown blade has groove structure, is convenient to convenient clamping in the subsequent techniques such as face coat.

Accompanying drawing explanation

Below in conjunction with accompanying drawing, technical solutions of the utility model are described further:

Fig. 1: schematic front view of the present utility model;

Fig. 2: schematic diagram is looked on a left side of the present utility model;

Fig. 3: the schematic diagram of the helical angle of seamed edge;

Fig. 4: the application schematic diagram of the utility model crown blade.

Detailed description of the invention

As shown in Figure 1 and Figure 2, the two screw lock crown blade in V-arrangement location, the cutter blade of crown blade removes its parallel portion by a cylinder, cutter blade grinds chip area 7, cutter blade right-hand member is removed V-shaped part 6 and is formed V-arrangement angle, angle is 90 ~ 120 °, and cutter blade right-hand member is provided with groove 15, and groove 15 is convenient to convenient clamping in the subsequent techniques such as face coat.Cutter blade left end is provided with the cutting edge be made up of chisel edge 8, transitional edges 9 and main cutting edge 10, chip area 7 forms main cutting edge 10 with the intersection of rear knife face, the angle formed between main cutting edge is drift angle 11, angle is 120 ~ 140 °, can adjust according to the difference of machined material, after two, the intersection of knife face forms chisel edge 8, grinds transitional edges 9 between main cutting edge 10 and chisel edge 8; The upper and lower face of cylinder of cutter blade grinds unnecessary part and retain a section spiral line formation seamed edge 13, cutter blade offers two for installing half shoulder hole 12 of housing screw, and the installation for blade is fastening.

As Fig. 3, seamed edge 13 is spiral faces of cylinder with one fixed width, operationally be used for the diameter of determining hole, its helical angle 14 is typically designed to 15 ° ~ 30 °, helical angle 14 is larger, and the cutting ability of crown blade is better, and helical angle 14 is less, the intensity of crown blade is higher, is more suitable for the processing of high hard material.

As Fig. 4, crown blade 2 is closely fixed on knife bar 1 by housing screw 3.

Crown blade has V-arrangement location structure, and V-arrangement location structure is fairly simple, and production precision is easy to ensure.V-arrangement location structure contact surface is comparatively large, and positioning precision is high, and structural reliability is good.

Crown blade has the locking mechanism of half shoulder hole, two screw lock structure, and auxiliary screw is many, and cost is very low.

Crown blade has groove structure, is convenient to convenient clamping in the subsequent techniques such as face coat.

It is to be understood that: the above is only preferred embodiment of the present utility model; for those skilled in the art; under the prerequisite not departing from the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
