Abstract
The invention discloses a kind of positioning tool, which belongs to wind electricity blade manufacturing technology field, and especially suitable for wind electricity blade sealing ring location and installation, which includes fixed part, positioning region.By be arranged positioning tool specific structure, can rapidly and accurately sealing ring installation site is positioned, solve the problems, such as sealing ring installation position inaccurate and installation take considerable time.
Description
Technical field
The present invention relates to positioning tools, especially suitable for wind electricity blade sealing ring location and installation.
Background technique
In the prior art, wind electricity blade can encounter rain and snow weather during real-world operation, and rainwater is flowed into along blade
In complete machine wheel hub, it will cause damage of components in wheel hub, bring serious property loss, to solve the above problems, wind-powered electricity generation leaf
Piece usually will be installed the sealing ring of rainwater-proof.Currently, the installation process of sealing ring is time-consuming and laborious, and without supporting and fixing, it is easy
Deformation dislocation, worker is not easy to operate, and production efficiency is low；Measurement data is more in installation process, and fault easy to operate directly affects sealing
Ring assembling quality.
Summary of the invention
When the technical problem to be solved in the present invention overcomes prior art installation sealing ring positioning to be not allowed and install consuming a large amount of
Between defect, a kind of positioning tool is provided.
The present invention by the following technical programs solve above-mentioned technical problem:
A kind of wind electricity blade sealing ring positioning tool is used for locating sealing ring, which is characterized in that the positioning tool includes fixing
Detachable connecting device is arranged in portion, positioning region, the fixed part and positioning region, and bolt is arranged in the fixed part and root of blade
It is connected and fixed.
In the technical scheme, by the way that the specific structure of positioning tool is arranged, sealing ring can be installed rapidly and accurately
Position is positioned, and solves the problems, such as that sealing ring installation positioning and installation take considerable time.
Further, the detachable connecting device includes bolt, nut.
Further, bolt, nut are set, fixed blade sealing ring is used for.
Further, the positioning region, fixed part are flange arrangement.
Further, the positioning tool further includes positioning pin.
Positive effect of the present invention is the provision of a kind of tooling that blade seal ring is fixedly mounted, tool structure letter
Single, location sealing ring position is accurate.
The present invention quickly accurately positions sealing ring installation site by positioning tool, greatly reduces worker
Labor intensity and wind electricity blade production cycle, improve the quality of production and production efficiency.

Specific embodiment
A preferred embodiment is named, and is become apparent from conjunction with attached drawing and completely illustrates the present invention.It should be pointed out that this
Locate described specific embodiment to be merely to illustrate and explain the present invention, the present invention is not limited to the present embodiment.With reference to Fig. 1,
Fig. 2, Fig. 3, the implementation case provide a kind of positioning tool of wind electricity blade sealing ring installation.
Positioning tool includes positioning region, fixed part, and the fixed part is fixedly connected by bolt with root of blade bolt hole,
The fixed part is fixedly connected with positioning region by bolt, nut.
Specifically, in a preferred embodiment, fixed part and positioning region are all made of disc flange structure, fixed part, positioning region
It has been sequentially distributed three circle screw holes outward from center, using the Screw hole structure of blade tip inherently, fixed part and root of blade
It is bolted and fixed, fixed part is fixedly connected with positioning region using bolt, nut.
In the present embodiment, according to sealing ring installation location dimension requirement, it is fixedly connected by inside and outside two circles bolt, nut
Determine portion and positioning region, outer ring bolt is distributed Zhou Jing and is greater than sealing ring outer diameter, and inner ring bolt is distributed Zhou Jing and is less than outside sealing ring
Diameter size, and guarantee inner ring screw tip inside the screw hole of positioning region, so that it is guaranteed that sealing ring end face can fit closely positioning
End surface.
Sealing ring fitting is fixed on by positioning end surface using bolt, nut, sealing ring positioning accuracy is improved and facilitates work
People's construction.
Secondly, on the fixed part circumference of blade bolt hole isoperimetric diameter, being uniformly arranged quantity to quickly position fixed part
Not equal location hole positions finger setting fixed part using 3-4 root, quickly, accurately by fixed part screw hole and blade tip screw hole pair
Together, fixed part is facilitated to be fixedly connected with root of blade bolt penetration hole.
Although specific embodiments of the present invention have been described above, it will be appreciated by those of skill in the art that this is only
For example, protection scope of the present invention is to be defined by the appended claims.Those skilled in the art without departing substantially from
Under the premise of the principle and substance of the present invention, many changes and modifications may be made, but these change and
Modification each falls within protection scope of the present invention.
