Embodiment
For example the present invention is done description in more detail below in conjunction with accompanying drawing:
In conjunction with Fig. 1～5, the device for fast generating of this helicopter airscrew pyramidal angle measurement light path, comprise sliding way 26 and glide path 25 two parts: glide path 25 comprises laser instrument 1 and reflective mirror 3, sliding way 26 comprises photelectric receiver 4 and reflective mirror 2.Laser instrument 1 is fixed on the slide 11 by laser holder 7, and wherein 8 is laser instrument dust cover.Reflective mirror 3 is fixed on the slide 12 by mirror holder 10, and wherein 9 is reflective mirror dust cover.Slide 11 and 12 can slide along guide rail 13, determines the position by scale 15.Guide rail 13 is fixed on down on dull and stereotyped 6 by guide rail fixed orifice 14.Reflective mirror 2 is fixed on the slide 20 by mirror holder 16, and wherein 17 is reflective mirror dust cover.Photelectric receiver 4 is fixed on the slide 21 by base 19, and wherein 18 is photelectric receiver dust cover.Slide 20 and 21 can slide along guide rail 22, determines the position by scale 24.Guide rail 22 is fixed on the upper flat plate 5 by guide rail fixed orifice 23.
This device for measuring common taper of rotor wings is when work, and laser instrument 1 is emission laser vertically, is radiated on the reflective mirror 2, after reflective mirror 2 is with the reflection of certain pitch angle, be radiated on the reflective mirror 3, after reflective mirror 3 reflects once more, form vertical light path once more, receive laser signal by photelectric receiver 4 at last.Be fixed on the same guide rail 13 for ease of light path adjusting laser instrument 1 and reflective mirror 3, can be along guide rail 13 horizontal slips.Laser instrument 1 is fixing by laser holder 7, and the angle of scalable in light path plane vertically launched to guarantee laser.Reflective mirror 3 is fixed on the mirror holder 10, and the angle of scalable in light path plane is vertical to guarantee laser light reflected.
In this helicopter device for measuring common taper, various metal devices all adopt stainless steel material, have certain rigidity and rigidity.Laser instrument 1 is emission laser vertically, is radiated on the reflective mirror 2, is radiated on the reflective mirror 3 after reflective mirror 2 is with the reflection of certain pitch angle, after reflective mirror 3 reflects once more, forms vertical light path once more, receives laser signal by photelectric receiver 4 at last.Thereby obtain three beams of laser, wherein two bundle laser beam are parallel, and another bundle laser beam and two collimated laser beams intersect, and three laser beam want the plane of coplane and composition vertical with the surface level that the blade rotation obtains.Can make laser meet the requirements of effect by regulating slide 11 profits 12, laser holder 7 and mirror holder 10.Can determine the position of each slide by scale 15 and 24.When carrying out helicopter airscrew pyramidal angle measurement, 3 rotors of installation on the rotor head are respectively standard rotor, tested rotor and follow rotor.The triangle projective planum that the cutting three beams of laser is formed when making the helicopter rotation.Three blades cut three beams of laser bundle blocking laser respectively with certain speed, every cutting beam of laser, pulse of photelectric receiver output.And discern these pulse signals with synchronizing signal, and these pulse signals are sent into processing of circuit, obtain the time interval of blade cutting three beams of laser interfascicular distance.Because the clipping time that the rotor of different taperings obtains is different at interval, so can calculate the rotor coning value of different taperings, the measurement of realization co-conicity of rotor wing of helicopter according to geometric relationship.Advantages such as this device for measuring common taper of rotor wings has simple in structure, and is easy to adjust, and installation and maintenance are simple and direct, and working stability is reliable can be used for the helicopter blade running elevation measurement, have very high practical value.
