Description
Technical field
The present invention relates to undercarriage field of structural design, particularly the upper lock lock post regulating mechanism of a kind of multiple degree of freedom aircraft.
Background technology
The upper lock lock post regulating mechanism of current domestic aircraft can only regulate by 2DOF, and needs spare part.
As shown in Figure 1, this connection is generally made up of its typical mechanism lock post, band tooth plate lock frame 1, tooth plate 12, screw, pad 13 etc. Realize lock post Y-direction by the relative position of adjustment lock frame and tooth plate to regulate, realize lock post Z-direction by increase and decrease pad and regulate. The main drawback that this kind connects is: lock post cannot be carried out X-direction adjustment, and need to prepare carried spares.
Summary of the invention
Technical problem to be solved by this invention is, not enough for prior art, it is provided that the upper lock lock post regulating mechanism of a kind of multiple degree of freedom aircraft, it is achieved the position adjustments of lock post X, Y, Z-direction, and without the need to spare part.
For solving the problems of the technologies described above, the technical solution adopted in the present invention is: the upper lock lock post regulating mechanism of a kind of multiple degree of freedom aircraft, comprises lock frame, and described lock frame both ends of the surface respectively comprise two fixing posts for fixing lock post; Two fixing posts of each end face are all fixed on one piece of retaining plate; It is hollow part between two pieces of retaining plates of described lock frame both ends of the surface; Two through holes respectively offered by described two pieces of retaining plates, and through hole position on two pieces of retaining plates is relative; Also comprise two eccentric splines, two spacing splines and two bolts; Described eccentric spline is connected and composed by two hollow circular cylinders, and one of them right cylinder bottom surface diameter is greater than another right cylinder bottom surface diameter, bottom surface diameter relatively large cylinder outside surface be provided with male spline, in the through hole of the less cylinder of holster of bottom surface diameter one piece of retaining plate wherein; Described spacing spline is enclosed within described male spline, and engages with described male spline; Described two bolt one end are stretched out from the through hole of another block retaining plate after being each passed through the right cylinder interior bone of described two eccentric splines; On bolt between described two pieces of retaining plates, cover has at least one pad, and described pad and described retaining plate interior side contacts.
Described spacing spline periphery is provided with projection, and described projection is provided with spacing groove, and the center of circle of described spacing spline is on the extended line of described spacing groove center line; Two fixed orificess have all been offered, insertion pin in described fixed orifices between two through holes of every block retaining plate; The bottom surface diameter that described pin is positioned at described fixed orifices external portion is greater than the bottom surface diameter that described pin inserts described fixed orifices interior portion; The part that two pins being positioned at same retaining plate with described eccentric spline stretch out described fixed orifices blocks described two spacing grooves respectively.
Regulate left and right pad quantity or spacer thickness can realize the adjustment locking post X-direction, rotary stopper spline during installation, utilize the eccentric rotation of spline can realize the adjustment locking post Y and Z-direction.
Compared with prior art, the useful effect that the present invention has is: the present invention can realize the position adjustments locking post X, Y, Z-direction, and without the need to spare part, it is achieved simple.
