The invention provides a photoelectric pod platform locking mechanism that comprises an outer frame main support, a locking steel sleeve, a locking rotating shaft, a locking pin, a torsional spring, alocking supporting plate, a locking rotating frame, locking rotating frame screws, locking supporting plate screws, an inner orientation locking support and an inner pitching locking support. On thebasis of mechanical limiting of a traditional pod platform, the platform locking mechanism is added and mainly comprises the torsional spring and the locking rotating shaft; the platform can rotate intwo directions and be locked at a fixed position at the same time through one locking mechanism under the driving of a motor, and repeated collision of the platform on mechanical limiting in the non-working state of the pod is avoided. During work, under reversed driving of the motor, unlocking of the platform can be achieved. On the premise that locking and unlocking platforms are met, small friction force is generated, and locking is firm and reliable.
Description
technical field [0001] The invention relates to the technical field of mechanical design, in particular to a locking mechanism for a photoelectric pod platform. Background technique [0002] In the traditional optoelectronic pod platform, the structure of the azimuth axis system and the pitch axis system are mainly constrained by mechanical limits, but due to structural space constraints and other reasons, the structure of the azimuth axis system and the pitch axis system inside the optoelectronic pod platform has no The locking mechanism causes the optoelectronic pod platform to repeatedly collide with the mechanical limit structure due to turbulence, maneuvering and other factors when the optoelectronic pod platform is in a non-working state. influences. Contents of the invention [0003] In order to solve the problems existing in the prior art, the present invention proposes a locking mechanism for the platform of the photoelectric pod, which can lock the rotation of t...
