Abstract
For a switching pin for angle displacement measurement, it is characterized in that: the described switching pin for angle displacement measurement, comprises and be provided with the faceted Coupling Shaft of anti-rotation, with the web joint of elastic gap, accommodate section, switching pin transition section; Wherein: be provided with the faceted Coupling Shaft of anti-rotation and be connected with the top that transition section is sold in switching, blessing section is sold transition section with switching and is connected, accommodating the side of section is hatch frame, the web joint in the flexible gap of connecting band, with on the web joint of elastic gap with through hole.Advantage of the present utility model: structure is simple, transmission is direct, little to space requirement, measuring accuracy is high, be applicable to engine variable blade self-locking nut locking mechanism and directly carry out angle displacement measurement, for other situations torsion angle transmission and measure also can be suitable for, improve measuring accuracy, reduce and mend labor content.
Description
Technical field
The utility model relates to the structure of Engine Block Test measuring system, particularly a kind of switching pin for angle displacement measurement.
Background technology
In the structural design of engine blower pneumatic plant, in order to improve aeroperformance, improve air-flow surge margin, generally adjustable support plate or adjustable stator blade are set on fan inlet and stator blade, call adjustable vane in the following text, the structure of adjustable vane arranges rotating shaft at blade upper and lower side, and arrange screw thread in adjustable vane upper end, after blade radial radiant type is installed to casing, tighten with self-locking nut.
In order to monitor the adjusting angle of adjustable vane in engine test process, need measure corner size in real time and control pressurized strut start to promote the angle that adjustable vane turns to needs.The method in the past measuring the adjustable vane anglec of rotation is the flexible start displacement of monitoring pressurized strut piston, according to the numerical value corresponding relation demarcated between blade rotating angle and pressurized strut amount of piston displacement, then inverse blade rotary angle adjusts blade angle by controlling pressurized strut start.This displacement method measures complex structure, and measuring accuracy is poor, and feedback chain length, is unfavorable for accurately measuring and controls adjustable vane established angle.
Need to design switching pin for adjustable vane rotational angle displacement being directly forwarded to measuring equipment under existing structure as far as possible few prerequisite of changing, can shorten driving-chain, measurement result is more precisely stablized, and controls feedback more timely for this reason.
Utility model content
The purpose of this utility model measures the exchanging structure of corner, and to be directly used in angle displacement measurement, spy provides a kind of switching pin for angle displacement measurement.
The utility model provides a kind of switching pin for angle displacement measurement, it is characterized in that: the described switching pin for angle displacement measurement, comprises and is provided with the faceted Coupling Shaft 1 of anti-rotation, with the web joint 2 of elastic gap, accommodates section 3, switching pin transition section 4;
Wherein: be provided with the faceted Coupling Shaft 1 of anti-rotation and be connected with the top that transition section 4 is sold in switching, blessing section 3 is sold transition section 4 with switching and is connected, accommodating the side of section 3 is hatch frame, the web joint 2 in the flexible gap of connecting band, with on the web joint 2 of elastic gap with through hole.
With the prismatic bulge-structure increasing friction factor on the internal ring wall of described blessing section 3.
The Coupling Shaft face of cylinder arranges anti-rotation facet to switching pin, drives sensor element to rotate during for being linked with sensor; Accommodate section elastic gap face is set, when with bolt by gap two corresponding surface near time, can adjustable vane be stepped up; Accommodate the prismatic bulge-structure of section, match with the set nut on adjustable vane, by male-female engagement, and ensure reliably to be connected with the set nut on adjustable vane by the clamping action of elastic gap.
Advantage of the present utility model:
Switching pin for angle displacement measurement described in the utility model, structure is simple, transmission is direct, little to space requirement, measuring accuracy is high, be applicable to engine variable blade self-locking nut locking mechanism and directly carry out angle displacement measurement, for other situations torsion angle transmission and measure also can be suitable for, improve measuring accuracy, reduce mend labor content.
Accompanying drawing explanation
Below in conjunction with drawings and the embodiments, the utility model is described in further detail:
Fig. 1 is the switching latch structure schematic diagram for angle displacement measurement.
