Description
Technical field
The present invention relates to a kind of method of rectifier passage measuring tool and measurement rectifier passage thereof.
Background technology
Engine, especially aeromotor, due to surge, performance inconsistency lattice, repeatedly need decompose, repair, test run, can reach delivery test.According to analysis, its reason is many-sided, but the quality of wherein double rectifier manufacture is one of major reason affecting engine performance.
Double rectifier is a vitals on engine, and its effect is rectification and guiding.As Fig. 1 to 2, double rectifier 1 is with a pin 2 by front-seat rectifier 3, rear row's rectifier 4 bit combination, and the inner ring of forward and backward row's rectifier adopts the four sections of welderings of manual argon arc welding inner ring, and outer shroud adopts EBW (electron beam welding) to be welded for one week; Forward and backward row's rectifier blank is fusible pattern integral precision casting, and wherein blade grid passage (being called for short: passage) size (at the bottom of passage footpath φ C, footpath, passage top φ D) casting ensures, surplus is left at other position, φ C place Geometrical Tolerance Principle
, namely deviation from circular from is not more than 0.3mm.
As Fig. 1 to 2, before, rear row's rectifier belongs to double shrouded wheel, by 23 uniform blades and in, outer wheel hub forms, blade profile processing is measured by model, footpath φ C size at the bottom of passage, deviation from circular from 0.3, the general vernier caliper measurement of footpath, blade grid passage top φ D size, because blade grid passage blade profile is along φ C, φ D cylindrical curve distributes, the oral area of cylinder only can be measured with general vernier caliper measurement, middle part can't detect, size can not get controlling, this cylinder size is by casting guarantee, but actual blank is not accomplished, all also leave surplus, at the bottom of passage, under top dimension can not get the prerequisite controlled, aisle spare reduces, unavoidable.
In order to the end, the top crudy that solve blade grid passage reach drawing requirement, how designing a set of special measuring tool, is the technical barrier that this area will solve.
Summary of the invention
Technical matters to be solved by this invention is to provide the high rectifier passage measuring tool of a kind of first-time qualification rate and measures the method for rectifier passage, and to make the bottom of the blade grid passage of rectifier, top crudy reaches drawing requirement.
For solving the problems of the technologies described above, the invention provides a kind of rectifier passage measuring tool, comprising: L-type base, mandrel, one group of axle sleeve and floating his-and-hers watches part; Base is welded by horizontal base and riser, and riser is vertically fixed on horizontal base side, riser has a horizontal through hole; Mandrel one end is passed described horizontal through hole and is connected on riser, the tolerance clearance 0-0.03mm of mandrel and described lateral aperture; Axle sleeve is enclosed within mandrel, and tolerance clearance 0.02-0.06mm, the tolerance clearance 0-0.045 of axle sleeve and part (inner ring of front or rear row's rectifier or the inner ring of double rectifier) endoporus.Described floating his-and-hers watches part floats and is placed on riser end face, and the used time can not take off.(can splice with standard gauge block); Described axle sleeve is one group, is respectively used to the measurement in assembly and separate room.
Apply the method that above-mentioned rectifier passage measuring tool measures rectifier passage, comprising:
During use, part is contained on axle sleeve external diameter, dial indicator measuring head refers at measuring tool his-and-hers watches " B1 or B2 " place, that is the his-and-hers watches place of φ C in footpath at the bottom of passage or footpath, passage top φ D size, the large pointer of dial gauge points to the zero-bit of index dial, and dial indicator measuring head reach is placed on footpath at the bottom of blade grid passage or footpath place, top by rotational parts simultaneously, by observing dial gauge index dial registration, φ C in footpath at the bottom of whole passage can be measured, deviation from circular from 0.3, or footpath, passage top φ D; In addition, also dial framework can be carried out along base side, measuring head is placed on footpath at the bottom of passage or footpath place, top, and rotational parts, carrys out footpath φ D at the bottom of φ C in footpath at the bottom of Measurement channel or passage, deviation from circular from 0.3.
In order to the detection of one-piece part (that is: the inner ring of front or rear row's rectifier) channel size, and add man-hour processor and grasp the size of process redundancy at any time, devise one group of forward and backward row's rectifier before combining, the Air conduct measurement of one-piece part is with axle sleeve (namely single-piece is measured with axle sleeve 15).Measure axle sleeve by single-piece and change assembly measurement axle sleeve, part is placed on axle sleeve, can measure forward and backward row's rectifier channel size, the crudy of part is monitored.
Technique effect of the present invention: the improvement of forward and backward row's rectifier of the present invention and double rectifier blade profile channel measurement method, not only simple to operate, directly perceived, be easy to realize, and thoroughly solve and measure inaccurate problem for many years, this not only can make processor grasp the size of process redundancy at any time, and for reviewer examines and determine, product is qualified noly to be provided conveniently, makes crudy be guaranteed.This overlaps measuring tool, can be used for the measurement of forward and backward row's rectifier on aircraft and double rectifier.For the axial flow compressor surge phenomenon of these engines eliminates a kind of harmful effect, improve the performance of engine.
