Description
Technical field
The present invention relates to rotary cutter, particularly relate to a kind of dismantled and assembled rotary cutter.
Background technology
nullRotary cutter generally includes cutting portion and clamping shank two parts，In the work process of rotary cutter，Only cutting portion participate in cutting and more fragile，In order to avoid the damage because of cutting portion will cause scrapping of whole rotary cutter，Extend the service life of rotary cutter，Generally rotary cutter is set to detachable cutting portion and clamping shank，The modes such as cutting portion is threaded connection are installed on clamping shank，If cutting portion occurs that cutting portion can be only changed in damage，But owing to threaded stationkeeping ability is not strong，Relatively it is difficult to ensure that card is installed in the dimensional uniformity of the cutting portion clamped on shank，Simultaneously in order to ensure bonding strength，Install、The rotation amount that five circles are above is all needed during dismounting of cutting portion，Operate very inconvenient，In prior art by regular screw threads connected mode is changed into multiple thread connect improve stationkeeping ability，Reduce rotation amount，But this mode easily occurs can not be quick when installing、The problem being accurately positioned，Cause needing repeatedly to be screwed in and out just completing correct installation.
Summary of the invention
The technical problem to be solved in the present invention is to overcome the deficiencies in the prior art, it is provided that a kind of bonding strength is high and loads and unloads dismantled and assembled rotary cutter fast, easily.
For solving above-mentioned technical problem, the present invention adopts techniques below side:
A kind of dismantled and assembled rotary cutter, including instrument toggle and the cutting part being arranged on described instrument toggle, described instrument toggle includes set negative winding stem and set handle tail, described cutting part includes cutting portion and clamping part, described instrument toggle is provided with clipped labels, described cutting part is provided with adjustment notch, and when described clamping part is loaded described set negative winding stem, described clipped labels is directed at described adjustment notch.
Further improvement as technique scheme:
Described clamping part is connected by multiple thread with described set negative winding stem.
The end face of described set negative winding stem be provided with clamping recessed, described clamping part be set in described clamping recessed in.
Described cutting part also includes being easy to handling instrument and clamps the handling moment of torsion face of described cutting part, and described handling moment of torsion face is arranged on described cutting portion one end near described clamping part.
Described adjustment notch is arranged on described handling moment of torsion face.
The recessed cavity of described clamping is the tapering conical surface that is identical and that shrink to described set handle tail with the axial cross section of clamping part, and 0.5 °≤γ≤30 ° of span of conical surface drift angle γ.
Stating and be provided with stage portion between cutting portion and clamping part, described cutting part is installed when putting in place on described instrument toggle, has distance d and 0 < d≤0.1mm between described end face and described stage portion.
Compared with prior art, it is an advantage of the current invention that:
The dismantled and assembled rotary cutter of the present invention includes instrument toggle and the cutting part being arranged on instrument toggle, instrument toggle includes set negative winding stem and set handle tail, cutting part includes cutting portion and clamping part, set negative winding stem is provided with clipped labels, clamping part is provided with adjustment notch, when clamping part being loaded set negative winding stem, clipped labels is directed at adjustment notch, can quickly, accurately complete the installation of cutting part, can not be accurately positioned before not havinging installation cause cannot quickly, the problem that is correctly completed installation.

Detailed description of the invention
Below with reference to Figure of description and specific embodiment, the present invention is described in further details:
Fig. 1 to Fig. 4 illustrates a kind of embodiment of the dismantled and assembled rotary cutter of the present invention, this dismantled and assembled rotary cutter includes instrument toggle 1 and the cutting part 2 being arranged on instrument toggle 1, instrument toggle 1 includes set negative winding stem 11 and set handle tail 12, cutting part 2 includes cutting portion 21 and clamping part 24, instrument toggle 1 is provided with clipped labels 3, cutting part 2 is provided with adjustment notch 4, when clamping part 24 being loaded set negative winding stem 11, clipped labels 3 is directed at adjustment notch 4, can be quickly, accurately complete the installation of cutting part 2, do not have because not being accurately positioned before installing that cause cannot be quick, the problem being correctly completed installation.
In the present embodiment, clamping part 24 is connected by multiple thread with set negative winding stem 11, it is ensured that the bonding strength of instrument toggle 1 and cutting part 2.
In the present embodiment, the end face 13 of set negative winding stem 11 is provided with clamping recessed 14, and clamping part 24 is set in clamping recessed 14.
In the present embodiment, cutting part 2 also includes the handling moment of torsion face 22 being easy to handling instrument clamping cutting part 2, and handling moment of torsion face 22 is arranged on cutting portion 21 one end near clamping part 24, it is simple to use handling instrument that cutting part 2 is carried out clamping.
In the present embodiment, adjustment notch 4 is arranged on handling moment of torsion face 22.
The cavity clamping recessed 14 is the tapering conical surface that is identical and that shrink to set handle tail 12 with the axial cross section of clamping part 24, and 0.5 °≤γ≤30 ° of span of conical surface drift angle γ, by clamp recessed 14 and clamping part 24 in axial cooperation, improve cutting part 2 and be arranged on the axial carrying capacity on instrument toggle 1, in the present embodiment, γ=10 °.
In the present embodiment; stage portion 23 it is provided with between cutting portion 21 and clamping part 24; when cutting part 2 is installed on instrument toggle 1 and is put in place; between end face 13 and stage portion 23, there is distance d; and 0 < d≤0.1; the accuracy of manufacture requirement of screw thread in clamping part 24 and clamping recessed 14 can be reduced, the protection instrument toggle 1 when threaded inefficacy, extend the service life of instrument toggle 1.
