Embodiment
Below in conjunction with the attached drawing in the embodiment of the present invention, the technical solution in the embodiment of the present invention is carried out clear, complete
Site preparation describes, it is clear that described embodiment is only part of the embodiment of the present invention, instead of all the embodiments.It is based on
Embodiment in the present invention, those of ordinary skill in the art are obtained every other without creative efforts
Embodiment, belongs to the scope of protection of the invention.
The blade root bolt embedment frock of the present embodiment as illustrated in fig. 1 and 2, including：Upper die and lower die, upper mold include：
Upper bracket 11, upper bolt hole plate 12 and make-up lock adjusting mechanism, lower die include：Lower carriage 21, lower bolt orifice plate 22 and lower tight lock
Adjusting mechanism.Upper bolt hole plate 12 is the identical semi-circular plate of specification with lower bolt orifice plate 22, and circumferential edges are evenly distributed with spiral shell
Bore trepanning 121 and 221.
Upper bolt hole plate 12 and lower bolt orifice plate 22 are separately mounted to tighten on lock adjusting mechanism and lower tight lock adjusting mechanism,
Tighten lock adjusting mechanism and lower tight lock adjusting mechanism is separately mounted to 21 on upper bracket 11 and lower carriage, for fastening upper spiral shell respectively
Keyhole plate 12 and lower bolt orifice plate 22, and adjusting upper bolt hole plate 12 and lower bolt orifice plate 22 align respectively, make upper bolt hole plate
12 and lower bolt orifice plate 22 form whole plectane, and plectane is horizontal by predetermined angle.After being placed due to blade, blade root
End face is not and horizontal plane, but is in the predetermined angle, therefore plectane will be horizontal by predetermined angle, so that
Plectane is parallel with blade root end face.
Make blade blade root when, adjust and fastened upper bolt hole plate 12 and lower bolt orifice plate 22 (i.e. formed one
Plectane) after, bolt sleeve is put into bolt sets of holes 121 and 221, due to plectane and blade root end face (during pre-embedded bolt, blade root end face
The right in Fig. 2) it is parallel, therefore bolt can perpendicularly enter into blade root end face through bolt sleeve, and ensure pre-buried spiral shell
Bolt centrad precision height (center of i.e. all bolts is all on a circumference), error is small.And blade and blade using the present invention
Root bolt embedment frock, without later stage other process, can have been saved a large amount of in leaf production just by bolt embedment in blade root
Time.
For preferably fixed and adjusting upper bolt hole plate 12 and lower bolt orifice plate 22, upper mold includes four make-up locks and adjusts
Mechanism：First, which tightens the lock make-up lock make-up lock adjusting mechanism the 15, the 4th of adjusting mechanism the 14, the 3rd of adjusting mechanism 13, second, tightens
Lock adjusting mechanism 16.Lower die includes tight lock adjusting mechanism under four：First time tight lock adjusting mechanism 23, second time tight lock adjusting machine
Structure 24, the three times tight lock adjusting mechanisms 25, the four times tight lock adjusting mechanisms 26.And four tighten under lock adjusting mechanism and four tightly
The boundary line that lock adjusting mechanism is connected to each other along upper bolt hole plate 12 and lower bolt orifice plate 22 is symmetrical arranged.
In the present embodiment, tightening lock adjusting mechanism and lower tight lock adjusting mechanism can use in (but not limited to) Fig. 3~5
Structure, tightening lock adjusting mechanism and lower tight lock adjusting mechanism includes：Supporting plate 41, tight jam plate 42, tight lock 43, bolt orifice plate branch
Seat 44, shaft 45, tight lifting pin 46, puller bolt 47 and two tight lock bolts 48.Tight jam plate 42 and tight lock 43 are installed on described
On supporting plate 41, respective top is each formed with gap, and the gap at top is oppositely arranged to be used to accommodate the shaft 45 to be formed
Groove 49.44 connection rotating shaft 45 of bolt hole board support, can 45 rotation around the shaft.Two tight lock bolts 48 are tightly locked through described
Plate 42 and tight lock 43, for locking tight jam plate 42 and tight lock 43.Shaft 45 is between two tight lock bolts 48, and shaft
45 axis is vertical with the axis of two tight lock bolts 48.The tight lock 43 is away from the side of the tight jam plate 42 formed with even
Logical through hole and bolt hole, and through hole is connected to the gap, tight lifting pin 46 is located in through hole, and puller bolt 47 passes through bolt hole
Tight lifting pin 46 is moved to gap direction, so that tight lifting pin 46 holds out against shaft 45, is rotated to avoid shaft 45.In use, unclamp
Puller bolt 47, enables shaft 45 to rotate, and locks adjusting mechanism for tightening, and second, which tightens lock adjusting mechanism 14 and the 3rd, tightens
Lock adjusting mechanism 15 rotates at the same time for one group, and it is same for one group that the first make-up lock adjusting mechanism 13 and the 4th tightens lock adjusting mechanism 16
Shi Xuanzhuan；For lower tight lock adjusting mechanism, second time tight lock adjusting mechanism 24 and the three times tight lock adjusting mechanisms 25 are same for one group
Shi Xuanzhuan, first time tight lock adjusting mechanism 23 and the four times tight lock adjusting mechanisms 26 rotate at the same time for one group, so as to adjust whole
The angle of plectane and horizontal plane.
