Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described further.
Be specific embodiment of the utility model such as Fig. 1-4, comprise sensor fixation plate 1, clapboard 2 is set below the sensor fixation plate 1, clapboard 2 is divided into a guide rail 3, clapboard 2 right-angle sides are near guide rail 3, and sensor fixation plate 1 is obliquely installed near the angle of wedge hypotenuse of clapboard 2.Sensor fixation plate 1 is head near clapboard 2 angle of wedge ends, is afterbody near right-angle side one end, and it is provided with front shoe 5 above head, be provided with afterbody fixed head 6 and sensor localization guiding mechanism above the afterbody; Front shoe 5 is provided with the accommodating through hole 501 of surveying sensor probe.Wherein, sensor fixation plate 1, clapboard 2 are connected both sides and are provided with and connect backplate 7 with guide rail.The present embodiment is made as triangle with the probe outline of institute's survey sensor 13, and at sensor 13 afterbodys two pilot holes is set.Through hole 501 shapes of tool front shoe 5 are set to del, can only have three angles to pack into the probe of limit sensor 13.Comprise the fast clamping plate 9 of afterbody orienting lug 8, afterbody, binding clasp 10 and two locating pins 12 of being located at below sensor fixation plate 1 afterbody at the sensor localization guiding mechanism of tool afterbody; The fast clamping plate 9 of afterbody are connected with the afterbody orienting lug and slidably are connected with axis hole by axle, and binding clasp 10 clamps or unclamps the fast clamping plate 9 of afterbody and afterbody fixed head 6.Two locating pins 12 are located on the afterbody fixed head 6, to determine sensor 13 installation directions, two pilot holes couplings of locating pin 12 and sensor 13 afterbodys, two locating pins 12 are all mated when putting in place, sensor 13 only has both direction to pack into vertically, the both direction that the pilot hole that two locating pins 12 are mated namely exchanges, again with the installation of the del through hole engagement limits sensor of front shoe 5, only have both to cooperate in the time of all can packing into, sensor 13 just can be clamped on the tool, this moment, sensor 13 attitudes were unique, had foolproof function.Simultaneously, the positioning step of sensor 13 heads and the front shoe 5 of tool head are close to, and sensor 13 head positions are reliably located.
Because during the actual installation state of aircraft engine speed probe, sensor 13 bar axles and phonic drum disk plane are 9 ° of angles, so it is 9 ° that the present embodiment adopts the angle of wedge of clapboard 2, make along the sensor fixation plate of its angle of wedge hypotenuse setting and the sensor 13 and 9 ° of test table face tilt angles of being fixed, namely be 9 ° of angles with the phonic drum disk plane that is arranged on the test job table top.Simultaneously, guide rail 3 bottoms are provided with a guide-track groove 301, are provided with slide block 4 below the guide-track groove 301, and guide rail 3 two sides of tail are provided with L-type backplate 11, and L-type backplate 11 is fixed on the slide block 4.The L-type backplate 11 of tool by guide-track groove 301, slide block 4 and guide rail 3 two sides of tail settings is installed on the translation stage on the test job table top, and can move forward and backward along sensor 13 axial directions, to regulate the air-gap separation between sensor 13 probes and the phonic drum.11 restrictions of the L-type backplate of afterbody tool swings, to guarantee that tool only moves forward and backward along the sensor axis direction; The slide block of front end then is used for compensation installation place, tool the place ahead, makes guide rail be in horizontality.Clapboard 2 by 9 ° of angles of wedge is slidingly matched with L-type backplate 11 and guide rail 3, when realizing dynamic test sensor 13 have with actual installation condition under identical state, to obtain more accurately dynamic test.
