In order to achieve the above object, the utility model provides a following technical scheme: a special fixture that is used for unmanned aerial vehicle vertical vibration, shock-testing, it includes: the inclined support frame is of a double-layer structure consisting of a bottom layer and a top layer, the bottom layer is fixedly connected with the top layer through a connecting beam, and the bottom layer is provided with a plurality of fixing holes; the restraint seats are arranged in a plurality of ways and are fixedly arranged at the top of the inclined support frame at intervals; the hoops are arranged in a plurality of ways and are connected with the tops of the constraint seats one by one through connecting arms at two ends.
Preferably, the connecting arm is a bolt penetrating through two ends of the constraint seat, and the connecting arm is in threaded fit with the constraint seat.
Preferably, the constraint seats respectively correspond to two ends of the inclined support frame and the front end of the wing of the unmanned aerial vehicle.
Preferably, the restraint seat and the hoop are respectively provided with a protective gasket at one side corresponding to the unmanned aerial vehicle; the protective pad is a polyurethane pad.
Preferably, the connection beam comprises a longitudinal connection beam and an oblique connection beam.
Preferably, reinforcing ribs are respectively arranged on two sides of each connecting beam.
The utility model discloses beneficial effect lies in: this structure can add the great unmanned aerial vehicle of overall dimension and hold fixedly, when carrying out the great unmanned aerial vehicle vibration of overall dimension, impact test, provides stable fixed centre gripping intensity, and its advantage lies in adopting this special fixture to vibrate, when impact test, more approaches service conditions, provides a conventional shaking table can't satisfy the novel anchor clamps structure of vibration, impact test condition for the great unmanned aerial vehicle of overall dimension.
Drawings
In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the drawings used in the description of the embodiments or the prior art will be briefly described below, it is obvious that the drawings in the following description are only some embodiments of the present invention, and for those skilled in the art, other drawings can be obtained according to these drawings without creative efforts.
Fig. 1 is the overall structure diagram of the present invention.
Detailed Description
The technical solutions of the present invention will be described clearly and completely below with reference to the accompanying drawings of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by a person skilled in the art without making creative efforts belong to the protection scope of the present invention.
According to fig. 1, a special fixture for testing vertical vibration and impact of an unmanned aerial vehicle comprises: the inclined support frame is of a double-layer structure consisting of a bottom layer 1 and a top layer 2, the bottom layer 1 is fixedly connected with the top layer 2 through a connecting beam 3, and the bottom layer 1 is provided with a plurality of fixing holes 5; a plurality of restraint seats 6 are arranged, and the restraint seats 6 are fixedly arranged at the top of the inclined support frame at intervals; the hoop 7 is arranged in a plurality of ways, and is connected with the top of the restraint seat 6 through connecting arms 8 at two ends one by one. The connecting arms 8 are bolts penetrating through two ends of the restraining seat 6, and the connecting arms 8 are in threaded fit with the restraining seat 6. The restraint seats 6 correspond to two ends of the inclined support frame and the front end of the wing of the unmanned aerial vehicle respectively. The restraint seat 6 and the hoop 7 are respectively provided with a protective gasket 9 on one side corresponding to the unmanned aerial vehicle; the protective pad 9 is a polyurethane pad.
Through the aforesaid setting, earlier with polyurethane pad tiling on the restraint seat 6 of bearing diagonal frame, prevent vibration, scratch unmanned aerial vehicle surface in the shock-testing, treat that unmanned aerial vehicle places the back, utilize linking arm 8 to pass through staple bolt 7 with unmanned aerial vehicle and lock on restraint seat 6, finally cause whole unmanned aerial vehicle to fix on anchor clamps, bearing diagonal frame's bottom 1 is through this screw and shaking table fixed connection, thereby accomplish the installation fixed work of anchor clamps, and can carry out follow-up test. This structure can add the great unmanned aerial vehicle of overall dimension and hold fixedly, when carrying out the great unmanned aerial vehicle vibration of overall dimension, impact test, provides stable fixed centre gripping intensity, and its advantage lies in adopting this special fixture to vibrate, when impact test, more is close to service condition, provides a conventional shaking table for the great unmanned aerial vehicle of overall dimension and can't satisfy the novel anchor clamps structure of vibration, impact test condition. Wherein the connecting arm 8 is realized by a bolt and extends downwards out of the top layer 2 of the inclined supporting frame through a threaded hole of the restraining seat 6, so that the clamped integral unmanned aerial vehicle can be reliably fixed on the inclined supporting frame.
