Description
Technical field
This utility model relates to a kind of rounding device, a kind of blower fan cylinder rounding device.
Background technology
Axial flow blower cylinder is the important component part of blower fan, and the rigidity of cylinder, circularity quality directly influence
The total quality of blower fan.If cylinder rigidity, circularity are not enough, easily cause blower fan to deform, not only affect outside blower fan
See and run, and affect fan efficiency.The rigidity of cylinder can add by increasing cylinder material thickness at present
Wide flange width realizes, but the circularity of cylinder is difficult to accurately control.Mainly due to cylinder is being made
Needing after completing to carry out flanged edge making flange at its end face, when making, current inner barrel is not placed and is appointed
What positioner, it is easy to make barrel distortion, and when after barrel distortion, be all by staff's hammer etc.
Cylinder is carried out estimating full circle by instrument, and therefore cylinder roundness cannot accurately control, when cylinder is installed to blower fan
After on, shell is touched in the place that impeller clearance can be caused little, and leaking out in big place, gap, thus has a strong impact on blower fan
Operation and efficiency.
Utility model content
For the problems referred to above, the problem that this utility model intends to solve is to provide a kind of simple and reasonable, use
The blower fan cylinder rounding device that convenient and swift and full circle is effective, it is possible to accurately control cylinder roundness.
For reaching above-mentioned purpose, this utility model by the following technical solutions: a kind of blower fan cylinder rounding device,
Including along screw mandrel, handwheel, right-handed nut, left-handed nut, link rod one, link rod two, jacking block, push rod and
Curved roof, described along being arranged with handwheel on one end of screw mandrel, from handwheel on the body of rod of the most suitable described screw mandrel
At one end arriving the other end and be sequentially provided with right-handed thread and left hand thread, described right-handed thread is provided with dextrorotation spiral shell
Mother, described left hand thread is provided with left-handed nut, described right-handed nut's outer wall encloses along its circumference one uniformly
It is provided with at least four link rods one, described left-handed nut outer wall encloses along its circumference one and is provided with at least four uniformly
Link rod two, the quantity of described link rod one and described link rod two is equal, and one_to_one corresponding is arranged, every pair corresponding
The described link rod one arranged and the other end of described link rod two are both connected on a jacking block, on every piece of described jacking block
Being respectively and fixedly provided with a push rod, every described push rod end is respectively and fixedly provided with a curved roof, every piece of described curved roof
The corresponding center of circle is same, and this center of circle is on the centrage of the most suitable described screw mandrel.
As preferably, the quantity of described link rod one and described link rod two is eight.
Effective achievement of the present utility model: this utility model is simple and reasonable, convenient to use, uses
Time, first turn clockwise handwheel, and now right-handed nut and left-handed nut are respectively to falling along screw mandrel two end motion,
It is located remotely from each other, promotes jacking block, push rod and curved roof inward collapsible simultaneously, thus this utility model is drawn in；
Then this utility model after drawing in is put in cylinder, then rotates counterclockwise handwheel, now right-handed nut and
Left-handed nut does relative motion, close to each other, promotes jacking block and push rod to stretch out simultaneously, thus by this reality
Open with novel, make curved roof be close to the inwall of cylinder, play good positioning action and full circle effect.
Therefore when body end surface carries out flanged edge making flange, cylinder will not be made to deform, it is possible to accurately application cylinder
Body circularity.
In sum, this utility model has simple and reasonable, convenient to use and full circle is effective
Feature, it is possible to accurately control cylinder roundness.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: 1-falls along screw mandrel, 2-handwheel, 3-right-handed nut, 4-left-handed nut, 5-link rod one, and 6-joins
Bar two, 7-jacking block, 8-push rod, 9-curved roof, 10-right-handed thread, 11-left hand thread.
Detailed description of the invention
In order to make those skilled in the art be better understood from this utility model scheme, below in conjunction with this enforcement
Accompanying drawing in example, carries out clear, complete description to the technical scheme in this utility model embodiment.
As it is shown in figure 1, the utility model discloses a kind of blower fan cylinder rounding device, including along screw mandrel 1,
Handwheel 2, right-handed nut 3, left-handed nut 4, link rod 1, link rod 26, jacking block 7, push rod 8 and arched top
Plate 9, falls and is arranged with handwheel 2 along on one end of screw mandrel 1, on the body of rod of the most suitable screw mandrel 1 from handwheel 2 institute at one end
Being sequentially provided with right-handed thread 10 and left hand thread 11 to the other end, right-handed thread 10 is provided with right-handed nut 3,
