Face, the blank of blower blade are placed on the upper surface of two cushion blocks, are positioned by one-to-one curved surface, and it is dynamic that pressing plate is pressed in blower
On the blank of blade, pressing plate is compressed by bolt and nut, and bolt lower end is connected on revolution bottom plate.
The revolution bottom plate is cuboid, length 420mm, width 400mm, thickness 45mm, width and thickness formation
Both sides of the face center is drilled with centre hole, and two parallel cushion blocks are parallel to length two sides and are mounted on revolution substrate interposition
It sets.
The centre hole at the revolution bottom plate side center is withstood by the thimble of vertical rotary workbench and centre passes through
The clamp of vertical rotary workbench clamps, while the centre hole for turning round bottom plate other side center passes through vertical rotary workbench
Auxiliary thimble is withstood.
The bolt is mounted on cushion block side, and the other side of bolt is also devised with supporting block, and supporting block lower end is supported on
It turns round on bottom plate, supporting block upper end is withstood below pressing plate.
The root end of the blank of the blower blade bores two centre holes, and mills out the rectangle of biting teeth jaw clamping
Bore a center centre hole in the integral shroud end face centre of block, the blank of blower blade.
The root end bores two centre holes and is designed as symmetrical centre hole.
It is an advantage of the invention that the blank of blower blade can be effectively clamped by the design of this positioning tool, and
Tooling cooperation revolution machining center can go out the rectangular block of centre hole and clamping with accurate machining, be used for subsequent blower blade
Blank clamped in the upper positioning of Four-axis milling center steering platform, in the blade root of the blank of blower blade easy to process, steam passage
Carry on the back the thinned face of arc, integral shroud, steam passage switching position etc.；This tooling using blower blade blank convex profile curved surface with
And blade root blank outlet skew back face and bottom surface as positioning datum, and clamping compresses, and tool base plate both ends are drilled with the centre of location
Centre hole is mounted on vertical rotary workbench after the positioning of one end, is drilled two centre hole of one end and has milled rectangular block clamping position
Afterwards, bottom plate revolution 180 degree bores one centre hole of integral shroud end.
Detailed description of the invention
Fig. 1 is schematic diagram of the invention.
Fig. 2 is top view of the invention (schematic diagram for omitting pressing plate).
Fig. 3 is the side view (support plate is omitted in figure) of Fig. 1.
Specific embodiment
Referring to attached drawing 1-3, blower blade bores three thimble location holes and mills clamping position tooling, it includes revolution bottom plate 1, pad
Block 2, pressing plate 3, turning round design on bottom plate 1, there are two parallel cushion blocks 2, and the upper surface of a cushion block is designed to blower blade
The identical curved surface 4 of the convex profile of blank 6, the upper surface of another cushion block are designed to that the blade root of the blank 6 of blower blade goes out
The identical curved surface 5 in gas side inclined-plane and bottom surface, the blank 6 of blower blade are placed on the upper surface of two cushion blocks 2, pass through one-to-one correspondence
Curved surface positioning, pressing plate 3 is pressed on the blank 6 of blower blade, and by bolt and nut compression, bolt lower end is connected to pressing plate 3
It turns round on bottom plate 1.
The revolution bottom plate 1 is cuboid, length 420mm, width 400mm, thickness 45mm, width and thickness formation
Both sides of the face center is drilled with centre hole 7, two parallel cushion blocks 2 be parallel to length two sides be mounted on revolution bottom plate 1 above in
Between position.
The centre hole at the 1 side center of revolution bottom plate is withstood by the thimble 11 of vertical rotary workbench and centre is logical
