Description
Technical field
The present invention relates to experiments to clamp device field, and dress is clamped more particularly, to a kind of engine blade of fir tree shape tenon
It sets.
Background technology
When blade design after processing is completed, in order to understand the vibration characteristics and fatigue properties of blade, verify the vibration of blade
Whether meet design requirement with fatigue behaviour, needs to carry out modal test and fatigue test to blade.Fir tree shape tenon starts
Machine blade is a kind of relatively common blade construction, and there are two have fir tree shape to common clamping device between gripping block and gripping block
Clamping face clamp blade, but in long-term use, gripping block cannot be conveniently adjusted clamping direction, only clamp or
Loosen two degree of freedom, cannot be satisfied the clamping of the engine blade of the fir tree shape tenon of different angle.
Invention content
To solve the above-mentioned problems, the present invention proposes a kind of engine blade clamping device of fir tree shape tenon so that
The clamping of the more flexible fir tree shape tenon blade for meeting different size of the gripping block of clamping device.
To achieve the goals above, the present invention adopts the following technical scheme that：A kind of engine blade folder of fir tree shape tenon
Tight device, the clamping device include the switch block after two up and down that right side is hinged, and preceding switch block is respectively articulated on the left of rear switch block；
It is provided with fir tree shape tooth between the preceding switch block, the left and right sides of the preceding switch block is respectively equipped with a pair of of connecting plate, on connecting plate
Equipped with bolt hole；The connecting plate energy rotational angle, fir tree shape tooth of the bolt passing through bolt hole fixed blade in preceding switch block
It is interior.
Further, the preceding switch block selects T7 Steel materials.
Further, the preceding switch block can be disassembled from rear switch block.
Further, each pair of connecting plate two preceding switch blocks it is upper set it is identical.
Further, the rear switch block is hollow block.
Further, gasket is installed between the bolt and bolt hole.
Further, the connecting plate includes turn hole, and turn hole is connected on the jack-post of preceding switch block.
Compared with prior art, the beneficial effects of the present invention are：
1. the device is adapted to the clamping of the engine blade of the different fir tree shape tenon of angle；
2. switch block is different suitable for making the preceding switch block for being shaken and being impacted to select to adapt to before the device can be dismantled.

Specific implementation mode
For a clearer understanding of the technical characteristics, objects and effects of the present invention, now control illustrates this hair
Bright specific implementation mode, but protection scope of the present invention be not limited to it is as described below.
As shown in Figure 1, Figure 2 and Figure 3, the present invention provides a kind of engine blade clamping device of fir tree shape tenon, institutes
It includes the switch block 1 after two up and down that right side is hinged, switch block 2 before 1 left side of rear switch block is respectively articulated with to state clamping device；Before described
It is provided with fir tree shape tooth 4 between switch block 2, the left and right sides of the preceding switch block 2 is respectively equipped with a pair of of connecting plate 3, is set on connecting plate 3
There is bolt hole 9；3 energy rotational angle of the connecting plate, the bolt 5 pass through 9 fixed blade 6 of bolt hole in the fir tree of preceding switch block 2
In shape tooth 4, switch block can be adjusted the angle neatly to be bonded with fir tree shape tenon and be clamped before such structure is.
Preferably, the preceding switch block 2 selects T7 Steel materials, T7 steel to have preferable toughness and hardness, is suitable for making
It is shaken and is impacted.
Preferably, the preceding switch block 2 can be disassembled from rear switch block 1, facilitated and adapted to fir tree shape tenon of different shapes
Engine blade.
Preferably, the position on two preceding switch blocks 2 of each pair of connecting plate 3 is identical.
Preferably, the rear switch block 1 is hollow block, reduces the weight of clamping device.
Preferably, gasket is installed between the bolt 5 and bolt hole 9.
Preferably, the connecting plate 3 includes turn hole 8, and turn hole 8 is connected on the jack-post 7 of preceding switch block.
The use step of the clamping device：According to the fir tree shape tenon shape of tested blade 6, correct forward is selected
Block 2 is hingedly mounted on rear switch block；Switch block 2 is so that blade 6 is fitted in the fir tree shape tooth of preceding switch block completely before being put into blade adjustment
4, switch block 2 clamps blade 6 before installation bolt 5 allows on link block 3.
It can obtain, which is adapted to the clamping of the engine blade of the different fir tree shape tenon of angle；It should
Switch block is different suitable for making the preceding switch block for being shaken and being impacted to select to adapt to before device can be dismantled.
Disclosed above is only presently preferred embodiments of the present invention, cannot limit the right model of the present invention with this certainly
It encloses, therefore makees ground equivalent variations according to the claims in the present invention, be still within the scope of the present invention.
