Detailed Description
The invention designs a set of simple, reliable and easy-to-operate taking-out tool, which can not only improve the working efficiency, reduce the damage to the airplane wheel to a certain extent, improve the strength of the part and meet the technical use requirements of long service life and high load of the airplane wheel.
An unmanned aerial vehicle wheel cotter pin extractor, as shown in fig. 1, comprising: the device comprises a first screw nut 1, a first connecting screw 2, an upper ball head 3, a lower ball head 4, a bolt 5, a cotter pin extractor body 6, a second connecting screw 7, a second screw nut 8 and an upper plate 9.
The split pin 11 for the unmanned aerial vehicle wheel is used for limiting and locking the wheel nut 10 and the wheel shaft, one end of the split pin 11 is inserted into a mounting hole of the wheel nut 10 and the wheel shaft, the other end of the split pin 11 is provided with a connecting hole, and the axis of the connecting hole is perpendicular to the axis of the split pin 11.
The cotter extractor body 6 is connected with the upper plate 9 through a first connecting screw 2, a second connecting screw 7, a first screw nut 1 and a second screw nut 8. The first connecting screw 2 and the second connecting screw 7 are axisymmetrical with respect to the cotter extractor body 6, and similarly, the first screw nut 1 and the second screw nut 8 are axisymmetrical with respect to the cotter extractor body 6. The lower ball head 4 is connected with the upper plate 9 through the upper ball head 3, and the lower ball head 4 can be driven to rotate by rotating the upper ball head 3. The lower ball head 4 is provided with a detachable structure, and the other end of the cotter 11 is connected with the lower ball head 4 through a bolt 5 and the detachable structure; the bolt 5 is inserted into the detachable structure and the connecting hole at the other end of the cotter 11 to fixedly connect the cotter 11 with the lower ball head 4. Specifically, as shown in fig. 4, the lower ball head 4 is provided with a sinking groove and a through hole, the sinking groove and the through hole are detachable structures, the sinking groove penetrates through the lower ball head 4 along the radial direction of the lower ball head 4, and the sinking groove is used for accommodating the other end of the cotter pin 11, so that the head of the cotter pin 11 can be allowed to pass through.
