Description

technical field [0001] The invention relates to a device that uses laser technology to complete the adjustment of the center of mass of the rotor so that it reaches a balanced state. Specifically, it relates to a laser precision weight removal system and method, which is mainly used to improve the balance precision of inertial navigation systems and jet engines. processing field. Background technique [0002] With the continuous improvement of the precision and stability of the inertial gyro instrument, the accuracy and process requirements for the dynamic balance of the gyro rotor are also increased. The deweighting balance is actually completed by changing the mass distribution of the rotor. In all precision machinery and instruments with high-speed rotating parts such as gyro motors, electric motors, jet engine moving parts, etc., the functional errors (such as drift effects on gyroscopes) and disturbing swings are often caused by residues in the rotating parts. caused b...

Problems solved by technology

However, this method has low balancing efficiency, poor positioning accuracy, high labor intensity, and low balancing accuracy. Frequent starting, weight removal, and stopping also affect the service life of the rotor

In addition, for the flexible gyro rotor with a special structure, due to the low strength of the flexible joint and the large force of manual degravity, it is easy to deform the ribs of the joint and directly affect the working stability of the gyro instrument; another way is to use laser Dynamic balance measurement and weight removal, but because the liquid floating gyro rotor can only detect the unbalanced position in the oil slick, it cannot be measured in high-speed rotation, so it is not suitable for laser dynamic balance measurement

Before the laser was used for balancing, it was reported abroad that electronic beam processing was used to achieve balance, but compared with the electrostatic gyroscope, because the electromagnetic field interference deflection is generated during the balancing process, and a vacuum system and a high-voltage system are also required, which limits its use. use
