Abstract

The invention belongs to the field of steering engine locking and particularly relates to an electric steering engine locking device. According to the technical scheme, the electric steering engine locking device comprises a fixed plate (1), a fastening screw (2), a connecting block (4), a friction plate (5), an armature (6), a coil (7), a case (8), and springs (9). The coil (7) and the circular armature (6) are disposed in the case (8). A motor shaft of an electric steering engine is connected with a locking device through the connecting block (4), the friction plate (5) and a central through hole of the fixed plate (1). When the coil (7) is not powered, the armature (6) and the friction plate (5) are compressed through the springs (9) and the motor shaft (3) is compressed and locked through the connecting block (4). When the coil (7) is powered, the armature (6) is separated from the friction plate (5) by electromagnetic force and the connecting block (4) is loosened. Automatic unlocking is achieved by power of the steering engine with no need of additional control signals, and the electric steering engine locking device has the advantages of operational reliability, simplicity in control and operation, easiness in installation and the like.

Description

technical field

[0001] The invention belongs to the field of steering gear locking, and in particular relates to an electric steering gear locking device. Background technique

[0002] The precision-guided bomb has a short working time, a small installation space for the servo system, strict weight requirements, and needs to withstand a large moment. Under such conditions, improving the reliability of the steering gear locking and unlocking has become a factor that must be considered in the design.

[0003] In the past, the steering gear was unlocked by receiving a signal from the flight control device to unlock the steering gear, and the signal lasted until the end of the flight. If the unlocking signal of the controller is sent abnormally, if it is not handled in time, it will not only burn out the controller, but also affect the flight of precision-guided bombs, and even endanger the safety of on-hook, which seriously restricts the improvement of equipment reliability. ...
