Technical field
The present invention relates to the processing technical field of auxiliary equipment of wind electricity blade, specifically a kind of wind turbine blade root
Bolt hole punching alignment system and its localization method.
Background technology
Glass fibre wind electricity blade is one of critical component of Wind turbines, and wind electricity blade passes through " T bolt connections "
Mode is connected with Wind turbines.Such a root connected mode design is needed after blade bonding forming with punch device in blade
Root is cut to blade root, milling, nut bore and bolt hole drilling.To ensure the bonding strength of root of blade, do not require nothing more than
All bolts hole are evenly distributed on the pitch circle of a certain diameter of root of blade end face, and bolt hole bore edges are to root of blade
The thickness of inwall and outer wall should also meet a certain numerical requirements.The rotation large arm of punch device, cutter unit, milling list at present
The integrated form combination of member, bolt hole units and nut bore units can meet wind power blade bolt hole and nut bore
The requirement such as axiality, pitch diameter, but the requirement of the inside and outside wall thickness in blade bolt hole needs to carry out several times before formal punching
Examination punching, the time for once trying punching are generally 30min or so.Once examination punching includes trying to play bolt hole impression, measurement each
Distance of the bolt hole center to blade shell inside and outside wall, milling bolt hole impression；Generally, a wall thickness is unsatisfactory for requiring just needs
The position of root of blade support or blade is adjusted, re-starts once examination punching；In addition, to avoid blade from trying punch-cuts, milling
Length of blade caused by mill vane end faces is less than theoretical value, more length surplus can be generally reserved in blade cuts, therefore
Examination punch out step before wind electricity blade formally punches can take the substantial amounts of time, reduce the production efficiency of blade, be also unfavorable for
The control of leaf weight.
The content of the invention
In order to solve the above-mentioned technical problem, the present invention provides a kind of wind turbine blade root bolt hole punching alignment system,
The alignment system realizes more accurately and conveniently positioning method by way of imager projection for punching, avoids traditional wind-powered electricity generation

And then the regulation up and down of optical imaging instrument height is realized, described optical imaging instrument is with calculating mechatronics, and optical imaging instrument
The rule blade root bolthole circle that calculator memory can be stored up is according to 1:1 ratio is projected in wind turbine blade root
On end face.
Connected between described optical imaging instrument and computer by connecting line.
The surrounding of the imaging chamber is made up of lighttight dividing plate.
A kind of wind turbine blade root bolt hole punching localization method, comprises the following steps：
Step 1: the root of wind electricity blade is cut and milling to blade needed for length, be made wind-powered electricity generation leaf to be punctured
Piece, it is standby；
Step 2: the root of wind electricity blade to be punctured made from step 1 to be inserted to the inside of imaging chamber, and make wind-powered electricity generation leaf
The root of piece is placed in the root adjusting bracket in imaging chamber；
Step 3: the imager support of regulation punch device cantilever tip, makes optical imaging instrument to required height；
Step 4: computer is opened, the rule blade root bolt hole point for being stored up calculator memory by optical imaging instrument
Butut is according to 1:1 ratio is projected on the end face of wind turbine blade root, is made to be formed on the annular end face of wind turbine blade root and is thrown
Shadow bolt hole；
Step 5: by the vertically and horizontally position of root adjusting bracket regulating wind power root of blade, make wind electricity blade root
The inner wall thickness of bolt hole is projected on portion's annular end face and outer wall thickness meets design requirement, that is, completes punching positioning.
Beneficial effect：
1st, a kind of wind turbine blade root bolt hole punching alignment system of the invention and its localization method, simple in construction,
Operability is good.It has been carried out relatively accurately, conveniently by way of imager projection for the bolt hole punch operation of wind electricity blade
Positioning, avoid the troublesome operation of examination punching before the punching of traditional wind electricity blade so that can after root of blade ends cutting, milling
Directly formally punched；And it will be clearly understood that arriving punching rear bolt hole center to blade before the punching of root of blade bolt hole
The distance of housing inside and outside wall；Punching process that can also be to blade bolt hole in the drill process of blade bolt hole is supervised in real time
Control, so as to improve the production efficiency of blade.
2nd, the hardware facility and software systems all technology maturations that alignment system of the invention is relied on, and cost is low, easily grasps
Make and install, the system can be formed using equipment such as currently used wind electricity blade punch device, optical imaging instruments.
3rd, alignment system of the invention is punched before blade formally punches without trying, therefore can be reduced more than blade length in reserve
Amount, be advantageous to the Weight control of blade；It can monitor whether the actual bolt hole of blade is distributed correctly in real time in blade drill process, and
Stop the error situation in blade bolt hole in time, improve the accuracy and technology stability of punching.
