Abstract
A two-dimensional nozzle bottleneck height measuring mechanism is characterized by comprising a top plate and a supporting mechanism. The supporting mechanism comprises short rods, long rods and damping rods, and is characterized in that the short rods and the long rods are hinged to form an equilateral parallelogram mechanism, the two ends of the damping rods are hinged to the short rods and the long rods respectively at the same time, and the supporting mechanism is formed by the short rods, the long rods and the damping rods. The top plate is hinged to the short rods of the supporting mechanism, and is provided with an angle dividing plate and a handle. The damping rods provide driving force to enable the equilateral parallelogram mechanism to move so as to drive the top plate to move up and down. The two-dimensional nozzle bottleneck height measuring mechanism has the advantages that the measuring processes when a two-dimensional nozzle is assembled, maintained and installed are simplified, the automation degree is high, the measuring result is high in accuracy, and the application range is wide.
Description
Technical field
The present invention relates to aeromotor Nozzle Design field, particularly a kind of two-dimensional nozzle venturi height measuring mechanism.
Background technology
Two-dimensional nozzle is rectangle along the cross section of engine axis direction, and during the different operating state, its width is constant, and then the height that only need to measure venturi during highly difference, so its measurement throat area converts and get final product.At present measuring mechanism commonly used is for the axisymmetric nozzle design, during measurement, needs that manually-operated is many, automaticity is low, measurement result accuracy is poor, can't effectively be applied on two-dimensional nozzle.In order in two-dimensional nozzle assembling and setting and installation use procedure, to record fast and accurately its venturi height, need the two-dimensional nozzle venturi height measuring mechanism that a kind of automaticity of design is high, measurement result accuracy is high, applied widely.
Summary of the invention
The objective of the invention is in order to record fast and accurately two-dimensional nozzle venturi height, the spy provides a kind of two-dimensional nozzle venturi height measuring mechanism.
The invention provides a kind of two-dimensional nozzle venturi height measuring mechanism, it is characterized in that: comprise top board 1 and supporting mechanism, wherein, supporting mechanism comprises quarter butt 2, stock 3 and damper rod 4, is specially:
Top board 1 quantity is 2.
The quantity of supporting mechanism is 2～8 covers.
In every cover supporting mechanism, the quantity of quarter butt 2 is 4, and the quantity of stock 3 is 2,4,6 or 8, and the quantity of damper rod 5 is 2,3,4 or 5.
The course of work of described two-dimensional nozzle venturi height measuring mechanism is:
Handle B on operator grasps top board 1, the application of force is compressed to suitable size by measuring mechanism, be placed into the nozzle throat place, under the effect of damper rod 4, measuring mechanism can tightly be fixed on two-dimensional nozzle venturi place, and with the folding and unfolding of nozzle throat corresponding deformation, as long as read the deflection angle of quarter butt 2 from the angle-differentiated dish A on top board 1, can obtain the venturi height by calculating.
Advantage of the present invention:
Two-dimensional nozzle venturi height measuring mechanism of the present invention, simplified the measurement in two-dimensional nozzle assembling and setting and installation use, and automaticity is high, and measurement result accuracy is high, applied widely.
The accompanying drawing explanation
The present invention is further detailed explanation below in conjunction with drawings and the embodiments:
Fig. 1 is two-dimensional nozzle venturi height measuring mechanism schematic diagram.
