Specific embodiment
With reference to the accompanying drawing, the utility model is described in detail.
In order to make the purpose of the utility model, technical solutions and advantages more clearly understood, below in conjunction with attached drawing and implementation
Example, the present invention will be further described in detail.It should be appreciated that specific embodiment described herein is only used to explain
The utility model is not used to limit the utility model.
Embodiment
A kind of blade root fixture including the pedestal 1 as support, is provided with the first folder on the pedestal as shown in Figures 1 to 4
Block 2 and the second fixture block 3,2 top of the first fixture block are provided with the first arc groove 4, which is provided with the second arc
Slot 5, first arc groove 4 and the second arc groove 5 are oppositely arranged to form the arc groove for assembling blade root, first fixture block and
The bindiny mechanism for tensing fixture block is provided between second fixture block.
It in the present embodiment, is designed by adopting a split structure fixture block, and adjusts two using bindiny mechanism
Spacing between a fixture block, and arc groove its main shape used is designed with the shape of blade root, in the same of adjustment spacing
When so that fixture block is more bonded blade root flute profile, ensure that clamping precision.As more specifical design, the bottom
It is provided with pilot hole on seat, in the mechanism processed required for being assemblied in by the pilot hole.Common assembly is to use
Screw rod connection.
Usually in blade design, and for more preferable clamping effect, and guarantee better chucking power, is specifically implementing
In mode, first arc groove 4 and the second arc groove 5 are respectively 2, are formed by first arc groove 4 and the second arc groove 5
2 arc grooves and 2 fixture blocks positioned at arc groove two sides.Contact surface when clamping is effectively guaranteed by the design method
Product, can fully ensure that clamping effect.
Meanwhile in order to improve the space fine-adjusting effect between fixture block, more specifically in design, first fixture block and second
The opposite side of fixture block offers the first groove 6 and the second groove 7 respectively to reduce the thickness of fixture block convenient for clamping blade root.The party
The design of formula can effectively ensure that spacing adjustment effect.
As more specifical design, in another specific embodiment, which is "u"-shaped groove, this is second recessed
Slot 7 is inverted "L" shape.The main purpose of the design method is to realize thickness of the thickness of the second fixture block less than the first fixture block.
