Inside and outside compound chamfers cutter
The utility model relates to rose reamer structure.
Rose reamer be assemblied on the lathes such as milling machine, drilling machine, planer, beveler for 60 degree of processing work or 90 degree of chamferings and taper hole, the cutter of reverse mould corner angle, belong to slotting cutter.Rose reamer is also chamfering device.Rose reamer is applied widely, is not only applicable to the chamfering of standard machinery workpiece, is more suitable for chamfering and deburring that precision baffles angle workpiece.
For outer chamfer machining along the river in workpiece, usually have interior rose reamer and outer rose reamer point.Normally respectively by chamfering inside and outside interior rose reamer and outer rose reamer successively processing work, this becomes complicated with regard to causing the operation of chamfer machining.
Adjustable inside and outside rose reamer (201310219921.2) as a kind of in Chinese invention application, comprise the knife bar be connected with the driving shaft of milling machine, knife bar is provided with two fixing lug boss along the radial direction of knife bar, moveable interior dise knife and cylindrical cutter is provided with between two fixing lug boss, the blade of interior dise knife and cylindrical cutter is positioned at the same side, interior dise knife and one of them fixing lug boss is removable is connected, cylindrical cutter and another fixing lug boss is removable is connected, interior dise knife is connected by alignment pin with cylindrical cutter.This technical scheme for fillet inside and outside different size part, the distance between the blade of adjustable interior dise knife and the blade of cylindrical cutter.
For another example rose reamer (201320821890.3) inside and outside Chinese utility model, cut groove by handle of a knife, lengthening handle, extension, insert groove, outer chamfering blades, cutter head, row, bolt, blade, interior chamfering blades form, it is characterized in that one end of extension is connected with handle of a knife by lengthening handle, the other end of extension arranges cutter head, on cutter head, groove is cut by the row of being provided with, row cuts in groove and is provided with insert groove, in insert groove, blade is installed, blade is fixed by bolts in insert groove, and the inside of handle of a knife, lengthening handle, extension is provided with internal cooling channel.
Above-mentioned two kinds of technical schemes represent the mainstream technology trend of the industry substantially, install inside and outside rose reamer simultaneously, make clamped one time just can process inside and outside chamfering simultaneously by bolt on handle of a knife.
But because rose reamer is installed by bolt, cause the job stability of rose reamer to there is certain limitation, the unstable rule brought due to mounting means can affect working (machining) efficiency and crudy, machining accuracy.
Utility model content
The purpose of this utility model is to propose a kind of inside and outside compound chamfers cutter, and it can solve the problem of job insecurity.
In order to achieve the above object, the technical scheme that adopts of the utility model is as follows:
Inside and outside compound chamfers cutter, it comprises a handle of a knife, and one end of described handle of a knife is one-body molded is connected with rose reamer and an outer rose reamer in one.
Preferably, interior rose reamer and outer rose reamer are in a distance.
Preferably, interior rose reamer is all connected with handle of a knife arc transition with outer rose reamer.
Preferably, the blade of interior rose reamer and the blade of outer rose reamer are positioned at the same side.
Preferably, interior rose reamer is rose reamer in tungsten steel alloy.
Preferably, outer rose reamer is the outer rose reamer of tungsten steel alloy.
Preferably, the angle of the blade of interior rose reamer and the axis of handle of a knife is 70 °-80 °.
Preferably, the angle of the blade of outer rose reamer and the axis of handle of a knife is 40 °-50 °.
The utility model has following beneficial effect:
Improve the job stability of rose reamer, improve working (machining) efficiency, crudy and machining accuracy.

Detailed description of the invention
Below, by reference to the accompanying drawings and detailed description of the invention, the utility model is described further.
Shown in composition graphs 1 and Fig. 2, a kind of inside and outside compound chamfers cutter, it comprises a handle of a knife 1, and one end of described handle of a knife 1 is one-body molded is connected with rose reamer 2 and an outer rose reamer 3 in one.Interior rose reamer 2 and outer rose reamer 3 are in a distance.
Interior rose reamer 2 is all connected with handle of a knife 1 arc transition with outer rose reamer 3.Concrete, the side that interior rose reamer 2 is connected with handle of a knife 1 and the side that outer rose reamer 3 is connected with handle of a knife 1 are a circular arc 4, and, the circular arc 4 of interior rose reamer 2 is oppositely arranged with the circular arc 4 of outer rose reamer 3, so just can strengthen interior rose reamer 2 and handle of a knife 1 and the adhesion between outer rose reamer 3 and handle of a knife 1, thus promote bond strength further.
The blade 21 of interior rose reamer 2 is positioned at the same side with the blade 31 of outer rose reamer 3.
In order to improve hardness and the wearability of rose reamer, interior rose reamer 2 and outer rose reamer 3 are made by tungsten steel alloy material, thus make rose reamer and the outer rose reamer of tungsten steel alloy in tungsten steel alloy respectively, thus substantially increase the life-span of cutter, also can improve crudy and precision simultaneously.
The blade 21 of the interior rose reamer 2 of the present embodiment is 74.7 ° ± 0.3 ° with the angle of the axis of handle of a knife 1.The blade 31 of outer rose reamer 3 is 45.0 ° ± 0.3 ° with the angle of the axis of handle of a knife 1.
As described in Figure 3, be schematic diagram that the present embodiment is processed workpiece 100.
For a person skilled in the art, according to technical scheme described above and design, other various corresponding change and distortion can be made, and all these change and distortion all should belong within the protection domain of the utility model claim.
