Description
Technical field
The utility model relates to measurers, and in particular to a kind of general blade height measurer of gas turbine blower rotor.
Background technique
It is surging forward under background in new round energy revolution, China Gas turbine industry and enterprise is increasing, enterprise investment
Enthusiasm is surging.Gas turbine is widely used in Aeronautics and Astronautics, ship, derived energy chemical as a kind of large-scale, advanced power device
Equal fields, all play a crucial role national equipment manufacture, national defense construction and national economy.Compressor rotor conduct
One of gas turbine chief component, is equipped with blade on compressor rotor, multiple blade screws are arranged in compressor rotor
Surface, height needs of the blade tip apart from rotor are met the requirements after compressor blade assembly.
It needs to detect blade height in compressor production process, since blade is set on rotor, rotor is circle
Cylindricality, the basal plane of blade bottom have certain radian, and ruler is difficult the vertical height of accurate directly measurement blade.
There are two ways to currently used for measurement compressor rotor blade vertical height, one is calculating method, for calming the anger
Machine rotor single-stage blade be even number measurement, generally using the symmetrical blade of outside micrometer measuring center diameter again with axis
Rotary drum section diameter, which makes the difference, is calculated data divided by 2 again.This method advantage is without special measuring tool, the disadvantage is that being unable to measure
Single-stage blade is the rotor blade heights of odd number, and the numerical value being calculated is the height average of two blades, median error
Add up more, the accuracy of final result can be impacted, finally influence product quality；Another method is sleeping using numerical control
Vehicle carries out the measurement of coordinate relative value, and this method advantage is that versatility is stronger, the disadvantage is that the high requirements on the equipment, and measurement is all every time
Need the clamping rotor on lathe, heavy workload, measurement and its inconvenience.
Summary of the invention
Purpose of the utility model is to solve the above problems and provide a kind of general blade of gas turbine blower rotor is high
Measurement tool, pedestal are directly placed on the pedestal of blade bottom, and the stabilizer blade of pedestal two sides can directly determine and blade bottom base
The outer section of radian where seat, ruler is vertical with outer section, and the ruler height of horizontal slide calliper rule alignment is the vertical height of blade.
To solve the above-mentioned problems, the technical solution adopted in the utility model is as follows:
A kind of general blade height measurer of gas turbine blower rotor, which is characterized in that 1 upper vertical of plinth is set
There is ruler 2,1 two sides of the bottom of pedestal are equipped with cylinder-shaped stabilizer blade 3, and two cylinder-shaped stabilizer blades 3 are arranged in parallel, two cylinder-shaped stabilizer blades 3
It is arranged in 1 bottom symmetrical of pedestal, sliding sleeve 4 is cased on ruler 2, sliding sleeve 4 is equipped with horizontal slide calliper rule 5, horizontal slide calliper rule 5 and 4 bottom of sliding sleeve
While flushing, sliding sleeve 4 is equipped with jackscrew.
It is optimized for, ruler 2 is socket joint type, and the outer ruler 21 of its underpart and the interior ruler 22 on top are socketed, and docking section
Divide and is fixed with jackscrew.
Compared with prior art, the utility model advantageous effects are as follows:
When measurement, the stabilizer blade of pedestal two sides is taken on the basal plane of blade bottom, two cylinder-shaped stabilizer blades and basal plane are complete
When contact, illustrates that two stabilizer blades and basal plane are circumscribed, the radial direction of blade bottom basal plane can be found by self weight, at this time ruler and leaf
The basal plane of piece bottom is vertical, and horizontal slide calliper rule are directed at vane tip, the corresponding ruler size of horizontal slide calliper rule can blade vertical height
Degree.
The utility model structure is simple, and measurement is convenient and efficient, accuracy is high, and practicability is very strong.
Detailed description of the invention
In order to illustrate the embodiment of the utility model or the technical proposal in the existing technology more clearly, below will be to embodiment
Or attached drawing needed to be used in the description of the prior art is briefly described, it should be apparent that, the accompanying drawings in the following description is only
It is some embodiments of the utility model, for those of ordinary skill in the art, is mentioned after not making the creative labor
Under, it is also possible to obtain other drawings based on these drawings.
