Abstract
The utility model provides a flange assembly positioning device for roots of embedded bolt fan blades. The flange assembly positioning device comprises two metal flange plates and a conical ring, wherein a plurality of positioning holes are distributed in the metal flange plates and the conical ring along a circumferential direction; and the quantities, the sizes and the positions of the positioning holes on the flange plates correspond to the quantities and the sizes of embedded bolts and the distribution of the embedded bolts at the root ends of the composite material blades for a wind generator set one by one. The flange assembly positioning device has safety and stability, is easy to operate and control and can be firmly and stably connected.
Description
Technical field
The utility model relates to a kind of flange installation and positioning structure, particularly a kind of MW class fan blade root pre-embedded bolt flange mounting and positioning device.
Background technique
The megawatt level wind power generation blade of China's production at present much all adopts root embedded nut structure.When blade is made, in the layer of the shop of root of blade, imbed threaded metalwork, wait after the completion of cure blade matched moulds, in nut, be screwed into bolt and be connected with wheel hub.And the orientation type of bolt adopts the metal flange dish to realize usually, if only carry out the location of bolt with a metal flange dish, this mode not only makes the Location accuracy of bolt poor, is easy to generate the deformation and the dislocation of bolt, causes the loss that can not save.And because the out-of-flatness property of root of blade end face, the bonding between metal flange dish and the glass fibre reinforced plastics is not necessarily firm, if in case bonding failure can cause titanic peril to blade and complete machine.
The model utility content
In order to overcome the technical problem that exists in the existing technology, the utility model provides a kind of pre-embedded bolt fan blade root flange mounting and positioning device, use this device can the reinforcement metal flange plate and the sealing of root, make combination tightr.
To achieve these goals, the utility model provides following technological scheme:
A kind of pre-embedded bolt fan blade root flange mounting and positioning device; Comprise two metal flange dishes and a tapered collar; On said metal flange dish and the tapered collar along the circumferential direction portion be laid with some positioning holes, the quantity of said positioning hole, size and the position on flange plate are corresponding one by one in the distribution of wind power generating set composite material blade butt with quantity, size and the pre-embedded bolt of pre-embedded bolt.
As a kind of optimal technical scheme of the utility model, all there is the axial screw thread hole at the two ends of said pre-embedded bolt.
As another optimal technical scheme of the utility model, said positioning hole can obtain through impact briquetting and die cast.
The beneficial effect that the utility model brings is: safety and stability, simple to operate easy to control, it is stable to be connected firmly.

Embodiment
Following facing combines accompanying drawing that the preferred embodiment of the utility model is done to set forth in detail, thereby so that advantage of the utility model and characteristic can be easier to it will be appreciated by those skilled in the art that the protection domain of the utility model made more explicit defining.
A kind of pre-embedded bolt fan blade root flange mounting and positioning device as shown in Figure 1; Comprise two metal flange dishes 3 and a tapered collar 2; Along the circumferential direction be laid with several positioning holes on said metal flange dish 3 and the tapered collar 2; The quantity of this positioning hole, size and the position on metal flange dish 3 are corresponding one by one at the distributing position of wind power generating set composite material blade butt with quantity, size and the pre-embedded bolt 4 of pre-embedded bolt 4; Wherein, all there is the axial screw thread hole at the two ends of pre-embedded bolt 4.
Specific operation process is: smear an amount of adhesive at blade 5 roots earlier; Again metal flange dish 3 and tapered ring 2 are sling and be placed in root position; Make position of positioning hole and blade 5 root embedded nut position consistency, this device is fixed, adopt tapered ring 2 sealing configurations of glass fibre reinforced plastics material through the screw rod that uses an end band six-sided nut 1; Rely on the distortion between tapered ring 2 and the metal flange dish 3, strict seal under the tension of high-strength bolt.Stablize the end time, treat to unload each screw rod after the adhesive completion of cure, after slowly take off the metal flange dish 3 and middle big tapered ring of outside, the flange plate of inboard is stayed on the blade 5, in each positioning hole, insert stud bolt again.Use this device can the reinforcement metal flange plate 3 with the sealing of root, make combination tightr.
The above; Be merely one of embodiment of the utility model; But the protection domain of the utility model is not limited thereto; Any those of ordinary skill in the art are in the technical scope that the utility model disclosed, and variation or the replacement that can expect without creative work all should be encompassed within the protection domain of the utility model.Therefore, the protection domain of the utility model should be as the criterion with the protection domain that claims were limited.
