Abstract
The utility model discloses a mechanically-clamped type indexable superhard tool bit. The utility model comprises a tool bar and a blade which is arranged on the end of the tool bar, wherein the bottom of the blade forms a tapered shape; the end of the tool bar is provided with a tapered positioning slot which is corresponding to the bottom of the blade, and a fixing clamp is arranged between the tool bar and the blade. Because the utility model adopts the mechanically-clamped type indexable superhard tool bit with a positioning cone, the positioning cone at the bottom of the blade is inserted into the tapered positioning slot of the tool bar, a problem that the blade slides is fundamentally solved, and use ranges of the mechanically-clamped type indexable superhard tool bit are further enlarged. In addition, the structure of an auxiliary cutting end and a cutting segment can also protect cutting tool edges, increase intensity and extend service life.
Description
Technical field
The utility model relates to a kind of industrial processes cutter, especially relates to the indexable superhard cutter of a kind of clip type.
Background technology
Superhard material comprises diamond, cubic boron nitride, they are two kinds of the highest materials of hardness in the world, wherein diamond hardness in all known substances is the highest, and cubic boron nitride hardness is only second to diamond, but its hear resistance and higher to the chemical stability of ferrous metal.Have good serviceability by superhard material powder and a small amount of bond through the superhard glomerocryst cutter material that the HTHP sintering forms, be widely used in the machining tool field.The indexable superhard cutter of wherein mechanical clamping type changes conveniently, can utilize characteristics such as cutting edge length to use, used in a large number.But the general indexable superhard cutter of clip type all adopts cylindric blade, only relies on top hold-down to fix, and the very easy slip of blade is difficult to satisfy processing request when carrying out two-way reciprocal machining.
Summary of the invention
The purpose of this utility model just is to design the indexable superhard cutter of a kind of clip type at the indexable superhard cutter of general clip type easy sliding problem of blade when carrying out two-way reciprocal machining, fundamentally solves blade sliding problem.
The purpose of this utility model can realize by following measure:
The utility model comprises knife bar and the blade that is placed in the knife bar end, and the bottom of blade is a conical in shape, and the end of knife bar is provided with and the corresponding taper locating slot in the bottom of blade, is provided with stationary fixture between knife bar and the blade.
Superhard blade in the utility model is divided into secondary segment of cutting, segment of cutting and positioning section from top to bottom in short transverse, and wherein secondary cutting end, segment of cutting and positioning section are cone shape.The positioning section tapering is 1-175 °.The segment of cutting tapering is 0-45 °.Secondary segment of cutting tapering is 0-90 °.
The utility model is because employing has the indexable superhard cutter of the clip type of locating cone, embed knife bar taper locating slot by location, blade bottom cone, fundamentally solve blade sliding problem, the scope of application of the indexable superhard cutter of clip type is further enlarged.In addition, the structure of secondary cutting end, segment of cutting also can be protected cutting blade.Gain in strength, increase the service life.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the structural representation of blade among the utility model figure;
Fig. 3 is the structural representation of locating slot on the knife bar among the utility model figure.
The specific embodiment
The utility model is done with detailed description below in conjunction with drawings and Examples:
As shown in the figure, the utility model comprises knife bar (2) and is placed in the blade (1) of knife bar end, the bottom of blade (1) is a conical in shape, the end of described knife bar (2) is provided with the corresponding taper locating slot in bottom (3) with blade (1), is provided with stationary fixture (4) between knife bar (2) and the blade (1).Superhard blade (1) is divided into secondary segment of cutting (1-3), segment of cutting (1-2) and positioning section (1-1) from top to bottom in short transverse, and wherein secondary cutting end, segment of cutting and positioning section are cone shape.The tapering of positioning section is 1 °-175 °.The segment of cutting tapering is 0-45 °.Secondary segment of cutting tapering is 0-90 °.Like this, secondary cutting end, segment of cutting and positioning section can be respectively three sections different cones of tapering, also a unified cone or two cones.
Specifically: the general indexable superhard cutter of clip type blade when carrying out two-way reciprocal machining easily slides, and have the indexable superhard cutter of the clip type of locating cone, embed knife bar taper locating slot by location, blade bottom cone, solve the blade orientation problem.The designed indexable superhard cutter of the clip type of locating cone that has is characterised in that: (superhard) blade (1) with band location cone, the special holder (2) and the taper locating slot (3) of band taper locating slot, its (superhard) blade (1) is to be formed by diamond or cubic boron nitride and a small amount of bond sintering, here (superhard) blade (1) is divided into secondary segment of cutting in short transverse, segment of cutting and positioning section, its middle and lower part cone is a positioning section, the centre is a segment of cutting, the top is secondary segment of cutting, the segment of cutting diameter is 5-50mm, the segment of cutting tapering is 0-20 °, the blade height overall is 6-30mm, and the locating cone height is 2-25mm, and tapering is 1 °-175 °.Taper locating slot (3) on the knife bar (2), back cut diameter is 5-50mm, and groove depth is 2-25mm, and the cell body tapering of taper locating slot is 1 °-175 °, and is identical with the positioning section tapering.
Operation principle of the present utility model is as follows: the pyramidal structure of the utility model blade bottom matches with the taper locating slot of the end of knife bar (2), and in conjunction with two between stationary fixture, thereby closely will be fixed together between knife bar (2) and the blade (1).And the respective outer side edges of secondary cutting end, segment of cutting can be protected cutting blade.
Claims (5)
1, the indexable superhard cutter of a kind of clip type, it comprises knife bar (2) and is placed in the blade (1) of knife bar end, it is characterized in that: the bottom of described blade (1) is a conical in shape, the end of described knife bar (2) is provided with the corresponding taper locating slot in bottom (3) with blade (1), is provided with stationary fixture (4) between knife bar (2) and the blade (1).
