Adopt said structure, due to the circle of helical blade projection formation rule, when for transmission field, owing to forming thinner blade in helical blade outer rim, when transmitting, blade can be formed with inboard wall of tube body and coordinate closely, is all transferred out by material, and good sealing effect between inboard wall of tube body, thickness in the middle part of helical blade ensures its holding capacity, is applicable to the transmission of fluid, semifluid etc.; This structure be used for field of machining time, can with drill bit with the use of, use as cutter as this helical wheel is arranged on drill bit afterbody, after piercing processing polished etc. is carried out to hole inwall, realize Precision Machining, may be used for the boring on earth's surface equally, all can reach good effect.
Described helical blade is two panels, and described in two panels, helical blade alternately spirals on center shaft, and two panels helical blade forms Central Symmetry relative to central shaft.Form Central Symmetry, when transmission or large hole machined, realize uniform force.
Described helical blade Inner edge is connected with central shaft, and this helical blade is reduced to Inner edge by middle part gradually at the thickness of radial direction, and the thickness of described Inner edge is greater than the thickness of outer rim, and described blade is tangent with projection circle.
This structure ensure that the intensity of helical blade.
Curvature outside described helical blade is greater than the curvature of inner side.Make helical blade cross section be bending crescent, stressed and laser propagation effect is good, ensure outside blade with body or hole inwall tangent.
The helix angle of described helical blade is 30 °-60 °.
The helix angle of described helical blade is 45 °, is that transmission or processing effect all reach optimum 45 ° time.
Centered by described projection radius of a circle, the 4-5 of axle radius doubly.
Described central shaft at least one end is provided with connecting hole, for being connected with actuating unit or cutter etc.
Described central shaft and helical blade one-body molded, one-body molded effective.
As mentioned above, the beneficial effects of the utility model are: the circle of the projection formation rule of helical blade, when for transmission field, owing to forming thinner blade in helical blade outer rim, when transmitting, blade can be formed with inboard wall of tube body and coordinate closely, is all transferred out by material, and good sealing effect between inboard wall of tube body, thickness in the middle part of helical blade ensures its intensity, is applicable to the transmission of fluid, semifluid etc.; This structure be used for field of machining time, can with drill bit with the use of, use as cutter as this helical wheel is arranged on drill bit afterbody, after piercing processing polished etc. is carried out to hole inwall, realize Precision Machining, may be used for the boring on earth's surface equally, all can reach good effect.

Detailed description of the invention
By particular specific embodiment, embodiment of the present utility model is described below, person skilled in the art scholar the content disclosed by this description can understand other advantages of the present utility model and effect easily.
As shown in Figure 1 to Figure 3, the utility model provides a kind of helical wheel structure, comprises central shaft 1, and central shaft 1 is provided with two panels helical blade 2, two panels helical blade 2 alternately spirals on central shaft 1, and two panels helical blade 2 forms Central Symmetry relative to central shaft 1.Form Central Symmetry, when transmission or large hole machined, realize uniform force, every sheet helical blade 2 at least forms a complete circle on central shaft 1, and helical blade 2 projects round 3 in being projected as of central shaft 1 axis, and the Inner edge 21 of helical blade 2 is connected with central shaft 1, this helical blade 2 is reduced by middle part 22 to Inner edge 21 and outer rim 23 gradually at the thickness of radial direction, and the thickness of Inner edge 21 is greater than the thickness of outer rim 23, blade is tangent with projection circle 3, and the outer rim 23 of helical blade 2 forms blade.
Curvature outside helical blade 2 is greater than the curvature of inner side.Helical blade 2 cross section is made to be bending crescent, stressed good with laser propagation effect, ensure outside blade with body or hole inwall tangent, the helix angle of helical blade 2 is 30 °-60 °, in this example, helix angle is preferably 45 °, be that transmission or processing effect all reach optimum 45 ° time, centered by the radius of projection circle 3, the 4-5 of axle 1 radius doubly.Central shaft 1 at least one end is provided with connecting hole 11, for being connected with actuating unit or cutter etc.
Central shaft 1 is one-body molded, one-body molded effective with helical blade 2, and 3D printing technique can be adopted shaping.
Adopt said structure, because helical blade 2 projects the circle of formation rule, when for transmission field, owing to forming thinner blade in helical blade 2 outer rim 23, when transmitting, blade can be formed with inboard wall of tube body and coordinate closely, is all transferred out by material, and good sealing effect between inboard wall of tube body, in the middle part of helical blade 2, the thickness of 22 ensures its holding capacity, is applicable to the transmission of fluid, semifluid etc., as cement mortar; When this structure is used for field of machining, can with drill bit with the use of, use as cutter as this helical wheel is arranged on drill bit afterbody, after piercing processing polished etc. is carried out to hole inwall, realize Precision Machining, may be used for the boring on earth's surface equally, the complete circular hole of an inner wall smooth can be formed, as traditional drilling equipment, irregular projection can not be formed at circular-hole internal-wall.
