Description
Technical field
The utility model relates to a kind of boring cutter, belongs to field of mechanical technique.
Background technology
In prior art, boring cutter is often used to carry out interior hole machined, reaming, profiling etc.In order to adapt to the needs in various aperture and hole depth and reduce the description of boring cutter, boring bar is become the bare bones-module of seriation by people with segment design.Suitable module can be selected according to the requirement of workpiece during use, piece together various boring cutter, thus simplify the Design and manufacture of cutter.But for the aperture that some are special, the especially hole of large-size diameter, adopts basic module to process, must design nonstandard boring cutter.
Utility model content
Technical problem to be solved by this invention is the defect overcoming prior art, provides a kind of boring cutter processing macropore, can process larger-diameter endoporus.
For solving the problems of the technologies described above, the invention provides a kind of boring cutter processing macropore, it is characterized in that,
Comprise the knife bar and cutter head that fit together;
Knife bar is stairstepping cylindrical bar, comprises a thick bar and a thin bar, and described thick bar is provided with one along the through circular mounting hole of the radial direction of bar, described cutter head is installed in installing hole; The sidewall of thick bar has two parallel planes, and this plane is arranged three through screwed holes to installing hole, screw rod is screwed in screwed hole, and is butted on the cutter head in installing hole;
Cutter head is the cylinder with installing hole form fit, a flat installed surface is cut in one end-grain cutting, this installed surface is arranged a leg-of-mutton groove, groove center arranges an installing hole, a wherein limit of leg-of-mutton groove is positioned at cylindrical installed surface edge, and leg-of-mutton blade is arranged in this groove by this installing hole.
In the edge that the end face of thick bar is crossing with installing hole, one gap is set.
When leg-of-mutton blade is installed in groove, one of them angle of blade is arranged in the gap at thick bar end face edge place.
Described plane is axially parallel with installing hole.
The side of described plane and cylindrical bar, described installed surface and cylindrical side all have a transition face.
The axis of described screwed hole is all vertical with the axis of described plane, installing hole.
The center arrangement of three screwed holes on a center line, the axis being parallel of this center line and installing hole.
The beneficial effect that the utility model reaches:
The boring cutter of processing macropore of the present utility model, novel structure, cost of manufacture is lower, can realize the roughing to larger-diameter hole or fine finishining, the maximum processing realizing hole to diameter 30-34mm.
Accompanying drawing explanation
Fig. 1 is knife bar schematic diagram;
Fig. 2 is cutter head schematic diagram;
Fig. 3 is knife bar, cutter head assembling schematic diagram.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is further described.Following examples only for clearly the technical solution of the utility model being described, and can not limit protection domain of the present utility model with this.
As shown in Figure 1, Figure 2 and Figure 3, the boring cutter processing macropore comprises the knife bar 1 and cutter head 2 that fit together.
Knife bar 1 is stairstepping cylindrical bar, comprises thick bar 11 and a thin bar 12, thick bar is provided with one along the radial through circular mounting hole 111 of cylindrical bar, for installing cutter head.Two parallel planes 113 are inwardly cut or milled out to thick bar along end face 112, plane 113 is axially parallel with installing hole 111.This plane 113 has a transition face 114 with the side of cylindrical bar.This plane 113 is arranged three through screwed holes 115 to installing hole, the axis of screwed hole 115 is all vertical with the axis of this plane 113, installing hole 111.When cutter head 2 is installed in installing hole 111, screw rod can be screwed in screwed hole 115, on the cutter head 2 that screw rod is butted in installing hole 111, locking cutter head 2.
Preferably, the center arrangement of three screwed holes 115 on a center line, the axis being parallel of this center line and installing hole 111.Out of plumb between the axis of installing hole 111 and the axis of cylindrical bar, namely installing hole 111 is the through in cylindrical bar of inclination, and installing hole 111 extends in cylindrical bar from the end face 112 of thick bar.In the edge that the end face 112 of thick bar is crossing with installing hole 111, this end arranges a gap 116.
Cutter head 2 is the cylinder with installing hole form fit, and a plane 21 has been cut in one end-grain cutting, and this plane 21 has a transition face 22 with cylindrical side.This plane 21 is arranged a leg-of-mutton groove 23, groove 23 center arranges an installing hole 24, and a wherein limit 231 of leg-of-mutton groove 23 is positioned at cylindrical horizontal edge.Leg-of-mutton blade can be arranged in this groove 23 by this installing hole 24, and one of them angle of leg-of-mutton blade is arranged in the gap 116 of end face.
The above is only preferred embodiment of the present utility model; should be understood that; for those skilled in the art; under the prerequisite not departing from the utility model know-why; can also make some improvement and distortion, these improve and distortion also should be considered as protection domain of the present utility model.
