This invention discloses an unmanned weapon platform mechanism with an adjustable damping buffer device, including a cradle mechanism for fixing and clamping the launcher barrel and receiver; the cradle mechanism cooperates with the gimbal mechanism via a pitch motor and crossed roller bearings; a buffer mechanism is symmetrically fixed at both ends of the cradle; an electronically controlled firing mechanism is fixed to the rear clamp base; a sight mounting mechanism cooperates with the cradle mechanism via a guide rail; and the bottom of the gimbal mechanism cooperates with the base mechanism. Compared with the prior art, this invention, by controlling the pitch and azimuth motors, can clamp the launcher for high-angle, high-precision dynamic tracking and aiming. After identifying the target, the launcher can be remotely fired by controlling the trigger servo. During firing, the launcher reciprocates under the action of recoil, compressing the buffer on the sliding guide rail, and achieves rapid stabilization, thus possessing the advantages of high firing accuracy, fast response speed, and lightweight structural design.
