Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the embodiment of the utility model is carried out
Clearly and completely describing, it is clear that described embodiment is only the utility model part of the embodiment, rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of creative work is made
The every other embodiment obtained, belong to the scope of the utility model protection.
Fig. 1-9 are referred to, the utility model provides a kind of technical scheme：
A kind of frock of fan blade test for static load loading blade, including upper framework 1, underframe 2, wherein in upper framework 1
Portion is provided with upper mounting plate 102, and its both ends is additionally provided with cylinder pin hole 103 and multiple circular hole A 101, and upper framework 1 passes through cylinder pin hole
103 connecting cylinder pin A 501 and straight pin B 601, plate A 5 and the bottoms of plate B 6 are provided with straight pin A 501 and straight pin B 601；
Plate A 5 and plate B 6 are connected by connecting rod 4；The inside of underframe 2 is provided with lower installation board 202, and its both ends is additionally provided with multiple circular hole B
201；Upper framework 1 and underframe 2 are connected by multiple connecting plates 3, upper framework 1 and the both ends of underframe 2 and front and rear are all provided with during connection
There is connecting plate 3 to fix；Backing plate 8 is installed, flexible support plate 7 is arranged on backing plate 8, soft on upper mounting plate 102 and lower installation board 202
Property supporting plate 7 contacts with fan blade.
The diameter of cylinder pin hole 103 is more than straight pin A 501 and the diameters of straight pin B 601, makes framework 1 and plate A 5 and plate B
6 have certain interval in junction, can be rotated in this junction during test；The length of connecting rod 4 is more than the upper length of framework 1；Plate A 5
There is certain warpage angle with the tops of plate B 6, warpage angle can be set to 45 °, and the circular hole A 502 for applying external force is provided with warpage
With circular hole B 602；Flexible support plate 7 is can be a kind of timber supporting plate, and it is directly contacted with fan blade, it is ensured that blade surface
Do not drawn injured.
Close to blade tip section, when test for static load loading blade is tested, fan blade deflection is big, now passes through the upper He of framework 1
After underframe 2 loads fan blade, the cylinder pin hole 103 at plate A 5 and the upper both ends of framework 1 of the insertions of plate B 6, then pass through connecting rod
4 connecting plate A 5 and plate B 6, during experiment, external force is applied on circular hole A 502 and circular hole B 602.With the application of external force, blower fan
