Description
The application is divisional application
The applying date of original application is：On 04 30th, 2014
Original application application No. is：201410180046.6
Original application it is entitled：A kind of dismantled and assembled rotary cutter.
Technical field
The present invention relates to rotary cutter more particularly to a kind of dismantled and assembled rotary cutters.
Background technology
Rotary cutter generally includes cutting portion and clamping shank two parts, in the course of work of rotary cutter, only cuts
It cuts portion and participates in cutting and more fragile, in order to avoid the damage because of cutting portion will lead to scrapping for entire rotary cutter, extend rotation
Turn cutting-tool's used life, usually set rotary cutter to detachable cutting portion and clamping shank, cutting portion passes through screw thread
The modes such as connection are installed in clamping shank, if cutting portion damage occurs and can only replace cutting portion, but are positioned due to being threadedly coupled
It is indifferent, it is more difficult to ensure the dimensional uniformity for the cutting portion being installed in clamping shank, while in order to ensure bonding strength, pacify
The rotation amount of five circles or more is required to when dress, dismounting of cutting portion, operation is very inconvenient, in the prior art by connecting regular screw threads
The mode of connecing is changed to multiple thread connection to improve stationkeeping ability, reduces rotation amount, but when this mode is easily installed cannot be fast
The problem of speed, accurate positionin, results in the need for repeatedly be screwed in and out to complete correctly to install.
Invention content
The technical problem to be solved by the present invention is to overcome the deficiencies in the prior art, provide that a kind of bonding strength is high and handling are fast
Fast, convenient dismantled and assembled rotary cutter.
In order to solve the above technical problems, the present invention uses following technical scheme：
A kind of dismantled and assembled rotary cutter, including tool toggle and the cutting part on the tool toggle, it is described
Tool toggle includes set negative winding stem and set handle tail, and the cutting part includes cutting portion and clamping part, the clamping part and institute
It states set negative winding stem to connect by multiple thread, the multiple-threaded each threaded line has different section configurations.
It is recessed that the end face of the set negative winding stem is equipped with clamping, the clamping part be set in the clamping it is recessed in.
The cutting part further includes the handling torque face that the cutting part is clamped convenient for handling instrument, and the handling are turned round
Square face is arranged in the cutting portion close to one end of the clamping part.
The axial cross section of the clamping recessed cavity and clamping part is identical and to the set handle tail contraction for taper
The conical surface, and 0.5 °≤γ≤30 ° of value range of conical surface apex angle γ.
Stage portion is equipped between the cutting portion and clamping part, when the cutting part is installed on the tool toggle
When position, there is distance d, and 0 ＜ d≤0.1mm between the end face and the stage portion.
A kind of dismantled and assembled rotary cutter, including tool toggle and the cutting part on the tool toggle, it is described
Tool toggle includes set negative winding stem and set handle tail, and the cutting part includes cutting portion and clamping part, the clamping part and institute
It states set negative winding stem to connect by multiple thread, the angle between each adjacent thread line of multiple thread is unequal.
The difference of angle between each adjacent thread line of multiple thread is Δ X, and 2 °≤Δ X≤15 °.
Compared with the prior art, the advantages of the present invention are as follows：
The dismantled and assembled rotary cutter of the present invention includes tool toggle and the cutting part on tool toggle, tool cover
Handle includes set negative winding stem and set handle tail, and cutting part includes cutting portion and clamping part, and clamping part passes through bull with set negative winding stem
It is threadedly coupled, multiple-threaded each threaded line has different section configurations, ensures that cutting part can only pass through single mode
It is installed on tool toggle, i.e., only needs the screw thread on cutting part and tool toggle is corresponding, so that it may quickly, accurately complete to cut
The installation for cutting component is not in that the problem of leading to not that installation is rapidly completed cannot be accurately positioned before installing.
The dismantled and assembled rotary cutter of the present invention includes tool toggle and the cutting part on tool toggle, tool cover
Handle includes set negative winding stem and set handle tail, and cutting part includes cutting portion and clamping part, and clamping part passes through bull with set negative winding stem
It is threadedly coupled, the angle between each adjacent thread line of multiple thread is unequal, therefore cutting part and tool toggle only have one kind
Clamping part can be correctly screwed into set negative winding stem by alignment, so as to quick, the accurate installation for completing cutting part, will not be gone out
The problem of leading to not that installation is rapidly completed cannot be accurately positioned before now installing.

Specific implementation mode
The present invention is described in further details below with reference to Figure of description and specific embodiment.
Fig. 1 to 4 shows that the first embodiment of the dismantled and assembled rotary cutter of the present invention, the dismantled and assembled rotary cutter include
Tool toggle 1 and the cutting part 2 on tool toggle 1, tool toggle 1 include covering negative winding stem 11 and set handle tail 12,
Cutting part 2 includes cutting portion 21 and clamping part 24, and clamping part 24 is connect with set negative winding stem 11 by multiple thread 3, bull spiral shell
Each threaded line of line 3 has different section configurations, to ensure that cutting part 2 can only be installed on tool by single mode
It on toggle 1, i.e., only needs the screw thread on cutting part 2 and tool toggle 1 is corresponding, so that it may quickly, accurately complete cutting part 2
Installation, be not in installation before cannot be accurately positioned lead to not quickly, be correctly completed the problem of installation.
In the present embodiment, the end face 13 of set negative winding stem 11 is equipped with clamping recessed 14, and it is recessed that clamping part 24 is set in clamping
In 14.
In the present embodiment, cutting part 2 further includes convenient for the handling torque face 22 of handling instrument clamping cutting part 2, dress
It unloads torque face 22 to be arranged in cutting portion 21 close to one end of clamping part 24, is easy to use handling instrument to cutting part 2 into luggage
Folder.
The cavity of clamping recessed 14 and the axial cross section of clamping part 24 are the cone that taper is identical and is shunk to set handle tail 12
Face, and 0.5 °≤γ≤30 ° of value range of conical surface apex angle γ, by be clamped recessed 14 and clamping part 24 in axial positioning,
The axial carrying capacity that cutting part 2 is mounted on tool toggle 1 is improved, in the present embodiment, γ=10 °.
In the present embodiment, stage portion 23 is equipped between cutting portion 21 and clamping part 24, when cutting part 2 is in tool toggle 1
On when being installed in place, there is distance d, and 0 ㎜ of ＜ d≤0.1 between end face 13 and stage portion 23, clamping part 24 and clamping can be reduced
The accuracy of manufacture requirement of screw thread on recessed 14, when being threadedly coupled failure, protection tool toggle 1, extends the use of tool toggle 1
Service life.
Fig. 5 shows second of embodiment of the dismantled and assembled rotary cutter of the present invention, the embodiment and the first embodiment
The difference is that：Angle between each adjacent thread line of multiple thread 3 is unequal, therefore cutting part 2 and tool cover
Handle 1 only has a kind of alignment that clamping part 24 can be correctly screwed into set negative winding stem 11, therefore cutting part and tool toggle are only
There is a kind of alignment that clamping part can be correctly screwed into set negative winding stem, so as to quick, the accurate peace for completing cutting part 2
Dress, in the present embodiment, the difference of the angle between 3 each adjacent thread line of multiple thread is Δ X, and 2 °≤Δ X≤15 °, i.e. X1
Difference with X2 is between 2 ° and 15 °.
