Abstract
The utility model discloses the location structure that a kind of handle of a knife is connected with main shaft, including the internal conical surface at handle of a knife and the outer conical surface being arranged at main shaft are arranged on, internal conical surface cooperates with outer conical surface, the conicity of the internal conical surface on the handle of a knife is 1：6, the handle of a knife is connected through a screw thread with main shaft.Outer conical surface on handle of a knife of the present utility model is improved to internal conical surface, and the orientational cone-shaped surface of main shaft is changed into internal conical surface, and handle of a knife is favorably protected in such setting, extends handle of a knife service life；Meanwhile, handle of a knife uses 1：The circular conical surface positioning of 6 tapers, can effectively reduce positioning contact length, reduce shank length, reduce handle of a knife weight, reduces cost.
Description
Technical field
The utility model is related to the location structure that a kind of handle of a knife is connected with main shaft, belongs to machining technology field.
Background technology
At present, handle of a knife uses 7 with main shaft：24 conical surfaces are connected, and handle of a knife is outer conical surface, is easily damaged；And the handle of a knife conical surface is more long,
Heavier-weight, is more expensive to manufacture.
The content of the invention
Technical problem to be solved in the utility model is：Overcome the deficiencies in the prior art, there is provided a kind of handle of a knife and main shaft
The location structure of connection, this kind of location structure makes handle of a knife be difficult to be collided.
In order to solve the above-mentioned technical problem, the technical solution of the utility model is：The positioning that a kind of handle of a knife is connected with main shaft
Structure, including it is arranged on the internal conical surface at handle of a knife and the outer conical surface being arranged at main shaft, internal conical surface and outer conical surface phase
Mutually coordinate, the conicity of the internal conical surface on the handle of a knife is 1：6, the handle of a knife is connected through a screw thread with main shaft.
Further, the contact length L=0.5~0.75*D of the internal conical surface and outer conical surface, D are straight for main shaft upper end
Footpath.
After employing above-mentioned technical proposal, the outer conical surface on handle of a knife of the present utility model is improved to internal conical surface, and will
The orientational cone-shaped surface of main shaft is changed to internal conical surface, and handle of a knife is favorably protected in such setting, extends handle of a knife service life；Meanwhile, handle of a knife
Using 1：The circular conical surface positioning of 6 tapers, can effectively reduce positioning contact length, reduce shank length, reduce handle of a knife weight, drop
Low cost.
Brief description of the drawings
Fig. 1 is structure principle chart of the present utility model；
In figure, 1, main shaft, 2, handle of a knife.
Specific embodiment
In order that content of the present utility model is easier to be clearly understood, below according to specific embodiment and with reference to attached
Figure, is described in further detail to the utility model.
As shown in figure 1, the location structure that a kind of handle of a knife is connected with main shaft, including be arranged on internal conical surface on handle of a knife 2 and
The outer conical surface on main shaft 1 is arranged on, internal conical surface cooperates with outer conical surface and constitutes the setting circle conical surface, the handle of a knife 2
On internal conical surface conicity be 1：6, the handle of a knife 2 is connected through a screw thread with main shaft 1.
As shown in figure 1, the contact length L=0.5~0.75*D of the internal conical surface and outer conical surface, D are main shaft upper end
Diameter.
Operation principle of the present utility model is as follows：
Outer conical surface on handle of a knife of the present utility model 2 is improved to internal conical surface, and the orientational cone-shaped surface of main shaft 1 is changed to interior
Handle of a knife is favorably protected in circular conical surface, such setting, extends handle of a knife service life；Meanwhile, handle of a knife uses 1：The circular conical surface of 6 tapers is determined
Position, can effectively reduce positioning contact length, reduce shank length, reduce handle of a knife weight, reduces cost.
Particular embodiments described above, the technical problem solved to the utility model, technical scheme and beneficial effect are entered
Go further description, should be understood that and the foregoing is only specific embodiment of the utility model, and without
It is all within spirit of the present utility model and principle in limitation the utility model, any modification, equivalent substitution and improvements done
Deng should be included within protection domain of the present utility model.
