Abstract
The utility model relates to the measurement of a multi-vane set countervane profile of a spaceflight, aviation, and gas turbine engine, in particular to the measurement of a narrow channel multi-vane set countervane profile. The multi-vane set countervane profile measuring tool is characterized by comprising a vane basin cross section sliding scale (2), a vane back cross section fixed scale (1), a left not-go-end (3), a cover plate (4), a clamping plate (5), positioning components (6), interconnecting components (7) and a right not-go-end (8). The multi-vane set countervane profile measuring tool is firstly used in detection of a profile of a narrow channel multi-vane set countervane, and solves the problem that a traditional vane body profile measuring tool can not detect profiles of intermediate vanes of the narrow channel multi-vane set countervane. Compared with a coordinate measuring machine, the efficiency is raised more than 10 times, and the multi-vane set countervane profile measuring tool is efficient and fast, is convenient to use, and is gradually popularized for use in real production.
Description
Technical field
The utility model relates to the measurement of the leafy group of guide vane profiles of engine such as space flight, aviation and combustion machine, the particularly measurement of leafy group of guide vane profile of narrow passage.
Background technology
In leafy group of guide vane production run of engine, need to carry out 100% profile measurement to several different cross sections of each blade blade.Guide vane passage is narrower and blade profile radian is larger due to leafy group, adopts traditional blade profile measuring tool to detect the blade profile of intermediate blade.The method that adopts three-dimensional, can carry out Measurement accuracy to leafy group of each blade profile of stator, but work efficiency is low, is not suitable for batch production.
Summary of the invention
(1) goal of the invention
The purpose of the present utility model is to provide a kind of leafy group of guide vane profile measurement frock.This frock can be measured leafy group of guide vane profile of narrow passage, and simple to operation, is applicable to batch production.
(2) invention technical scheme
A kind of leafy group of guide vane profile measurement frock the utility model proposes, comprising: leaf basin cross section slide rule 2, blade back cross section scale 1, left not-go-end 3, cover plate 4, clamping plate 5, positioning element 6, link 7 and right not-go-end 8.It is characterized in that: the contrary to reason opinion of the curve form size of blade back cross section scale 1 and measured blade and blade curved surface is in full accord, and a connecting cross beam is extended at the leading edge place of blade back cross section scale 1, and crossbeam passes between cover plate 4 and clamping plate 5.The curve form size of leaf basin cross section slide rule 2 is in full accord with the theoretical curved surface in the blade and blade basin cross section that will measure, a crossbeam is extended at the leading edge place of leaf basin cross section slide rule 2, crossbeam is connected with cover plate 4 with link by positioning element, in the time of together with blade back cross section slide rule 1 mates with leaf basin cross section slide rule 2, the blade profile profile forming is in full accord with the theoretical blade profile profile that will measure, and its two end will form a rectangular recess, this groove must be a definite standard value, for slip gauge, detects.Left not-go-end 3 and right not-go-end 8 are installed respectively in blade back scale two ends, prevent that use procedure middle period basin slide rule assembly from skidding off blade back scale crossbeam slide rail.
Left not-go-end 3 is backing pin, and right not-go-end 8 is straight pin.
Positioning element 6 is that register pin, link 7 are screw.
(3) beneficial effect
Leafy group of guide vane profile measurement frock of this utility model used first in the profile of leafy group of guide vane blade of narrow passage detects, and solved the problem that traditional blade profile measuring tool can not detect leafy group of stator intermediate blade blade profile of narrow passage.Compare with three coordinates, efficiency improves more than 10 times, and efficient quick is easy to use.This utility model is used more widely gradually in actual production.
Accompanying drawing explanation
Fig. 1 blade blade profile detects the structural representation of frock.
Embodiment
This example is a kind of for certain machine five leaf group turborotor blade profiles detection frock, comprises blade back cross section scale, leaf basin cross section slide rule, backing pin, cover plate, clamping plate, straight pin, screw and straight pin.Its middle period basin cross section slide rule, cover plate, clamping plate, straight pin and connection are assembled, and blade back cross section scale crossbeam slide rail and leaf basin slide rule assembly are moving to be coordinated, and backing pin and straight pin 8 are assemblied in blade back scale crossbeam two ends and play position-limiting action.
Described blade back cross section scale is the laminar model of a curved surface, and its curvature is identical with the theoretical blade back of measured blade.The camberline of each blade back cross section scale is identical with the theoretical curve in detected respective vanes blade blade back cross section, near blade back cross section scale, has a circular hole, and assembling backing pin is used, it is stationary fit, there is a circular hole crossbeam slide rail end away from scale, assembles spacing straight pin use, is also stationary fit.
Leaf basin slide rule is the laminar model of a curved surface, and its curvature is identical with the theoretical leaf basin of measured blade blade.The camberline of each leaf basin slide rule is identical with the theoretical curve in detected respective vanes blade leaf basin cross section, away from the connection of leaf basin cross section slide rule with there being 4 circular holes on crossbeam, it is for precise positioning is used, used with screw fastening cover plate and clamping plate when each 1 circular hole of both sides is assembling when middle 2 holes are assembling.The square opening of fastening formation and blade back cross section scale are slided and are joined.
Cover plate is a rectangular metal plate, has the circular hole of straight pin precise positionings for 4 circular holes with screw fastening and 2 assembly connections above, when there is a larger circular port centre in order to reduce frictionalwear with the sliding timing of blade back cross section scale.
Screw is standard hex screw, when assembling, plays the role of fastening.
Backing pin and straight pin are the cylindric pin of root, and top is sphere, and diameter is identical with the pin-and-hole of blade back cross section scale, leaf basin cross section slide rule, cover plate and clamping plate, and stationary fit with it.
When during detection, the numerical value of the formed rectangular recess of end of blade back cross section scale and leaf basin cross section slide rule and theoretical profile design, the numerical value of groove contrasts, and draws the result of the blade profile girth of a garment.
Using method:
Along blade back cross section scale crossbeam slide rail, pull open leaf basin slide rule assembly, open frock, frock is put on measured blade blade cross section, first blade blade back and corresponding frock are tightly pasted and, then the leaf basin cross section slide rule assembly that slides makes its leaf basin cross section that laminating will detect as far as possible clamping.
With clearance gauge, check each profile penetrability of blade and carry out respective record.
With the formed rectangular recess numerical value of end of blade back cross section scale and leaf basin cross section slide rule, evaluate the girth of a garment of blade profile.
Along blade back cross section scale crossbeam slide rail, pull open leaf basin slide rule assembly, open and take out frock.
