Buffering and driving system of missile folding mechanism

Abstract

The invention relates to a buffering and driving system of a missile folding mechanism. The buffering and driving system of the missile folding mechanism comprises an ignition mechanism at one end of an actuator cylinder and a piston in the actuator cylinder and driven by the actuator cylinder. The ignition mechanism comprises a grain in the actuator cylinder and an electric spark pipe out of the grain, a partition plate is positioned between the grain and the electric spark pipe to separate the grain from the electric spark pipe, and the electric spark pipe ignites the grain. A piston rod is mounted on one end of the piston, and the piston rod stretches out of the other end of the actuator cylinder and is connected with the folding mechanism through a connecting piece. The actuator cylinder is divided into a power cavity and a buffering cavity, a communicating channel parallel to an axis of the actuator cylinder is arranged on an inner wall of the actuator cylinder, one end of the communicating channel is communicated with the power cavity, and the other end of the communicating channel is connected with the buffering cavity. The buffering and driving system of the missile folding mechanism has the advantages that principle is simple, moving speed of the piston can be controlled, buffering effect is achieved, sufficient power output is guaranteed, and the system is capable of meeting buffering technology demand of various missile folding mechanisms.

Description

technical field [0001] The invention relates to the technical field of missile drive structure design, in particular to a missile folding mechanism buffer drive system. Background technique [0002] In order to meet the design needs of folding mechanisms such as missile folding wings, folding tail fins, and folding antennas, the driving system of the folding mechanism is required to have a driving function to ensure reliable switching of the mechanism, and at the same time, it is required to have a buffer function to ensure the integrity of structural parts and electronic components, especially for Sensitive electronic components such as image / command antennas and folding wings / tails with large external loads and easy-to-change load directions. Generally, the power sources such as spring force type, compressed air force type, and gas pressure type in traditional technology cannot meet the requirements of large load output, buffer effect and small volume design at the same ti...

Problems solved by technology

Generally, the power sources such as spring force type, compressed air force type, and gas pressure type in traditional technology cannot meet the requirements of large load output, buffer effect and small volume design at the same time, so a buffer drive system is required, which requires both to ensure the folding The mechanism can be deployed smoothly and reliably to change angles, and it is also necessary to avoid shock damage to structural parts and sensitive electronic components when in place
