Automatic rocket straightening device based on CAN bus control

Abstract

The invention discloses an automatic rocket straightening device based on CAN bus control. The automatic rocket straightening device comprises a double-shaft tilt angle sensor, a supporting platform, a control system, a speed reducer transmission mechanism and a ball screw transmission mechanism. According to the automatic rocket straightening device based on CAN bus control, the double-shaft tilt angle sensor sends collected information to a CAN bus through a CAN bus communication device, an engineering machine reads current angle information on the CAN bus through the CAN bus communication device, and an alternating-current servo motor needing to be adjusted is judged and determined according to an engineering machine software algorithm; the engineering machine transmits a command to a straightening controller through the CAN bus communication device, the straightening controller controls three motor drivers to drive the alternating-current servo motor to rotate or stop rotating, and the alternating-current servo motor serves as an executing mechanism to drive a ball screw transmission mechanism to do linear motion through a speed reducer; and a ball screw drives one vertex of the supporting platform connected with the ball screw to ascend and descend, and straightening of a rocket is achieved. The device is suitable for straightening the rocket.

Description

technical field [0001] The invention relates to the technical field of rocket automatic straightening, in particular to a rocket automatic straightening device based on CAN bus control. Background technique [0002] With the development of science and technology in the new era, the rapid launch capability of rockets has become an important research direction for rocket launches. A certain rocket needs to be manually operated and straightened before launch, which can no longer meet the requirements before launch. [0003] The existing rocket straightening device manually adjusts the ground support device and judges the datum level with the output of the level measuring instrument. Manual straightening often requires experienced personnel to operate, and it takes a long time and the accuracy cannot be guaranteed. It is not automatically adjusted by the system. The expected requirements are not met, and the anti-interference ability is not strong. Due to the high precision requ...

[0002] With the development of science and technology in the new era, the rapid launch capability of rockets has become an important research direction for rocket launches. A certain rocket needs to be manually operated and straightened before launch, which can no longer meet the requirements before rocket launch.

[0003] The existing rocket straightening device manually adjusts the ground support device and judges the datum level with the output of the level measuring instrument. Manual straightening often requires experienced personnel to operate, and it takes a long time and the accuracy cannot be guaranteed. It is not an automatic adjustment of the system. Therefore It does not meet the expected requirements and the anti-interference ability is not strong. Due to the high precision requirements of the rocket launch, the alignment of the rocket is very important to the launch of the rocket, which affects the normal progress of the subsequent launch process. Therefore, a CAN bus-based control is proposed. The rocket automatic straightening device is of great significance
