Abstract
The invention discloses a spraying pipe diameter measurement tool for an engine. The spraying pipe diameter measurement tool for the engine comprises a ruler measurement head, a fixing clamping hoop, a fixing nut, a replaceable measurement head, a ratchet, a pawl, a force adjustment bolt, a spring, a pawl fixing wheel, a rotary screw and a measurement tool shell, wherein the ruler is arranged on the rotary screw through the fixing clamping hoop; the fixing nut is arranged on the measurement tool shell; the replaceable measurement head is fixed to the measurement tool shell through the fixing nut; the rotary screw is arranged on the measurement tool shell and is rotatable; the ruler measurement head is connected with the rotary screw through screw threads; the pawl fixing wheel is fixed with the rotary screw integrally through a radial threaded pin; the pawl is fixed to the pawl fixing wheel through the spring and the force adjustment bolt; the ratchet is connected with the pawl fixing wheel through the pawl. The spraying pipe diameter measurement tool for the engine has the advantages that the diameter measurement of a spraying nozzle of the engine in a working state is realized by simulating airflow expansion force, the accuracy of spraying area measurement of the engine is guaranteed, and moreover, the spraying pipe diameter measurement tool for the engine is simple in structure, convenient to operate and easy to implement.
Description
Technical field
The present invention relates to diameter of nozzle of aircraft engine tail fields of measurement, particularly a kind of engine jet pipe diameter measuring tool.
Background technology
By adjustable jet tube critical cross-section area, change the operating mode of engine, for guaranteeing the accuracy of engine operating condition, needing can Measurement accuracy area of injection orifice.Because engine tail nozzle is comprised of adjustment sheet, adjustment sheet is deformable, and the major function of jet pipe is that high temperature, high-pressure gas are expanded and accelerate and discharge, and pipe critical cross-section is subject to gas tension, can bad student's distortion.Existing survey instrument cannot analog gas bulging force, cannot measure the working diameter of jet pipe.
Summary of the invention
The object of the invention is, in order to solve prior art, cannot measure engine jet pipe working diameter problem, spy provides a kind of engine jet pipe diameter measuring tool.
The invention provides a kind of engine jet pipe diameter measuring tool, it is characterized in that: described engine jet pipe diameter measuring tool, comprises scale gauge head 1, fixing hoop 2, hold-down nut 3, test probe replaceable 4, ratchet 5, ratchet 6, adjusts power bolt 7, spring 8, ratchet fast pulley 9, rotary screw 10, measuring tool housing 11;
Wherein: scale gauge head 1 is arranged on rotary screw 10 by fixing hoop 2, hold-down nut 3 is arranged on measuring tool housing 11;
Test probe replaceable 4 is fixed on measuring tool housing 11 by hold-down nut 3, rotary screw 10 is installed on measuring tool housing 11 and can be rotated, scale gauge head 1 and rotary screw 10 are threaded connection, ratchet fast pulley 9 is by radially threaded and rotary screw 10 are fixed as one, ratchet 6 is fixed on ratchet fast pulley 9 by spring 8 and the power of tune bolt 7, and ratchet 5 is connected with ratchet fast pulley 9 by ratchet 6.
Described measuring tool housing 11 is framed structure.
On described scale gauge head 1, with scale.
By rotation torsion-adjustable ratchet device, make scale gauge head protruding, when reaching the gas tension of jet pipe, torsion-adjustable ratchet structure is thrown off automatically, scale gauge head stops stretching out, and tightens the bolt on fixing hoop, and scale gauge head is fixed on to measuring tool object, prevent that scale gauge head from moving, and takes out reading by measuring tool.
Advantage of the present invention:
Engine jet pipe diameter measuring tool of the present invention, simulates flow expansion power by employing, has realized the diameter measurement of engine nozzle duty, guarantee the accuracy of engine spray area measurement, and it is simple in structure, easy to operate, is easy to realize.
Accompanying drawing explanation
Below in conjunction with drawings and the embodiments, the present invention is further detailed explanation:
Fig. 1 is engine jet pipe diameter measuring tool measuring tool schematic diagram.
