A Programmable Controlled Electromagnetic Pin-Gear Pair Shafting Locking Mechanism

Abstract

An electromagnetic bolt-gear pair type shafting locking mechanism capable of capable of being controlled through programming comprises a micro controller part, a locking telescopic mechanism part and a locking gear shafting. The electromagnetic bolt shafting locking mechanism controls switch-on or switch-off of a relay through micro controller signals, switch-on or switch-off of an electromagnetic bolt coil connected to the relay in series is controlled, and therefore a coil magnetic field is controlled to finish the target that a bolt ejection shaft is ejected into and out of a locking gear groove, and finally the shafting locking and opening functions are achieved. The electromagnetic bolt-gear pair type shafting locking mechanism has the advantages of being compact in structure, capable of locking at any angle and automatic alignment, reliable in performance and the like, and the mechanism can be applied to a micro controller program algorism to control locking and unlocking of a mechanical shafting, and is suitable for a stable tracking platform system and other electromechanical systems with the shafting locking requirement.

Description

technical field [0001] The invention belongs to the field of aviation remote sensing electromechanical design, and relates to a shaft system locking mechanism that has been applied in the aviation remote sensing two-axis stable tracking platform system, and realizes the digital signal of the programmable micro-controller for the aviation remote sensing two-axis stable tracking platform system. The locking and unlocking functions of the azimuth axis and the pitch axis can also be applied to occasions that require program-controlled locking and unlocking of the shafting system. The invention is suitable for aviation remote sensing equipment and other electromechanical systems that require shafting locking. . Background technique [0002] The stable tracking platform is the key equipment of the aerial remote sensing system. Its main function is to isolate the disturbance of the carrier, so that the optical axis (Line of Sight, LOS) can keep tracking the target stably in the ine...

In addition, the Chinese patent document CN102628692A is the closest existing technology of the present invention. The turbulence and acceleration of the aircraft carrying the remote sensing load during the climb and landing process are too large, and the remote sensing load will cause a relatively large impact on the aviation remote sensing stable tracking platform. Under the action of a large impact force, the torque motor needs a large current input to output a suitable torque to offset the impact force to ensure the stability of the load, but this will cause excessive power consumption and potential mechanical damage. to bad effects
