Abstract
This utility model is related to a kind of turbine blade frequency measurement frock, the chuck body made including metal derby, chuck body includes base and centre exceeds the boss of base, the front and back ends of boss are equipped with a limited block contour with it, offer on boss and run through its front/rear end and the blade root with turbine blade matches the blade root slot of shape, gap is offered on base below blade root slot, a coordinating block being connected with hydraulic pump is snapped in, the middle part of coordinating block has the strip jacking block protruding its upper surface in gap.By coordinating block, blade is coordinated in blade root slot, and compressed by hydraulic pump, then by the further stabilizer vane of strip jacking block on coordinating block, reliably can fix turbine blade without causing blade injury, facilitate the frequency of pilot blade；In frequency measurement, product shakes, and more stable with hydraulic pressure and bolt presses, measurement error is less；Not only easy for installation, work efficiency improves, and yield rate is improved, and so that frequency of vibration data accuracy is substantially improved.
Description
Technical field
This utility model is related to turbine blade technical field, especially a kind of turbine blade frequency measurement frock.
Background technology
, as a high-end equipment, it is with high content of technology for steam turbine, and technological requirement is high.As steam turbine core component it
One blade is more intended to the tight standard of high standard, and its technical specification more must not be ambiguous.In addition to design, material, technological requirement, to leaf
It is indispensable that the quality of piece is set up successive check.Blade is being loaded onto rotor, the frequency of vibration to blade before threading turbine body
Carrying out test is very crucial and necessary work.
Because frequency measurement is that necessary test verification, therefore must be before assembly it is impossible to load onto re-test after rotor to blade
Complete.Blade is big and small, of all kinds, and species is various, and quantity is quite big, so being part heavy task to blade frequency, special
It is not how various blades are fixed, facilitate the frequency of vibration that frequency meter accurately measures blade to be a big problem.
Number of patent application 201320445948.9 discloses a kind of steam turbine rotor vane frequency measurement frock clamp, in fixture originally
Different blade root slots are opened on body, to coordinate the shape of the blade root of tested blade, tested blade is inserted with corresponding blade root slot,
Then adjusted by bolt and blade is fastened in blade root slot, finally fixture and blade are fixed on bench vice, tap
Blade, frequency meter records frequency of vibration data.Adjusted by bolt and blade is fastened in blade root slot, true blade is tight
Gu unstable, the frequency of vibration data recording has deviation, and bolt adjusts the blade that also can wear and tear, and has much room for improvement.
Utility model content
The technical problems to be solved in the utility model is：Based on the problems referred to above, provide a kind of turbine blade frequency measurement frock.
This utility model solves its technical problem and be employed technical scheme comprise that：A kind of turbine blade frequency measurement frock, bag
Include the chuck body that metal derby is made, described chuck body includes base and centre exceeds the boss of base, before described boss,
Rear end is equipped with a limited block contour with it, boss offers and runs through its front/rear end and the blade root with turbine blade
The blade root slot of the shape that matches, the base below described blade root slot offers gap, has snapped in one and hydraulic pressure in described gap
The coordinating block that pump is connected, the middle part of described coordinating block has the strip jacking block protruding its upper surface.
Further, offer, in the middle of the bottom of described coordinating block, the connecting hole being connected with hydraulic pump.
Further, described limited block offers the bolt hole for both are connected with boss.
Further, the height of described boss is the 1/2 of substructure height.
The beneficial effects of the utility model are：This utility model passes through coordinating block and coordinates blade in blade root slot, and leads to
Cross hydraulic pump fastening, then by the further stabilizer vane of strip jacking block on coordinating block, can reliably fix turbine blade and not
Blade injury can be caused, facilitate the frequency of pilot blade；In frequency measurement, product shakes, more stable with hydraulic pressure and bolt presses, surveys
Amount error is less；Not only easy for installation, work efficiency improves, and yield rate is improved, and makes frequency of vibration data accuracy significantly
Improve.

Specific embodiment
Presently in connection with accompanying drawing, this utility model is described in further detail.These accompanying drawings are the schematic diagram of simplification,
Basic structure of the present utility model is only described in a schematic way, therefore it only shows the composition relevant with this utility model.
As shown in Figures 1 to 3, a kind of turbine blade frequency measurement frock, the chuck body made including metal derby, chuck body
Exceed the boss 2 of base 1 including base 1 and centre, the front and back ends of boss 2 are equipped with a limited block 3 contour with it, boss 2
On offer and run through its front/rear end and the blade root with turbine blade matches the blade root slot 2-1 of shape, under blade root slot 2-1
Offer gap 1-1 on the base 1 of side, in the 1-1 of gap, snap in a coordinating block 4 being connected with hydraulic pump, the middle part of coordinating block 4
There is the strip jacking block 4-1 protruding its upper surface, in the middle of the bottom of coordinating block 4, offer the connecting hole 4-2 being connected with hydraulic pump.
Wherein, limited block 3 offers the bolt hole 5 for both are connected with boss 2.
As preferentially, the height of boss 2 is the 1/2 of base 1 height.So design it is ensured that whole chuck body steady
Qualitative.
This utility model, when using, opens up blade root according to the blade root shape of different leaves on the boss 2 of chuck body
Groove 2-1, is fixed on boss 2 with the blade root coordinating measured blade, in the corresponding blade root slot 2-1 of tested blade insertion,
Coordinating block 4 snaps in the gap 1-1 of base 1 and withstands blade, by hydraulic pump, blade is fastened in the blade root slot 11 of device, joins
Close strip jacking block 4-1 on block 4 in frequency measurement can stabilizer vane further, by the limited block 3 of the front and back ends of boss 2, anti-
Only in test process, boss 2 slides and unifies the fixing height of chuck body, and all fixations finish, and tap blade, and frequency meter is surveyed
Obtain frequency of vibration data.In frequency measurement, product shakes, and more stable with hydraulic pressure and bolt presses, measurement error is less.
With above-mentioned according to desirable embodiment of the present utility model for enlightenment, by above-mentioned description, related work people
Member can carry out various change and modification completely in the range of without departing from this utility model technological thought.This reality
The content being not limited in description with new technical scope it is necessary to determine its technology according to right
