Air suspension reversing frame of static balancing machine and air suspension type static balancing machine

Abstract

The invention discloses an air suspension reversing frame of a static balancing machine and an air suspension type static balancing machine. The air suspension reversing frame of the static balancing machine is adopted to support a test frame; the space between a reversing shaft and an air suspension shaft sleeve is filled with air with certain pressure, so that the reversing shaft and the air suspension shaft sleeve are separated, an air suspension structure is integrally formed; a flexible connecting mechanism is adopted, a double-range sensor is arranged, so that the installation of a tested body is completed at one time on the same test bench, the high-precision measurement of the static unbalance of the tested body is realized under the condition that the installation reference of the tested body is not changed; and a damping mechanism is arranged, so that the vertical vibration of the test frame generated after the rotating mechanism rotates is effectively reduced. The air suspension reversing frame is good in structural stability and high in adjustment and measurement precision.

Description

technical field [0001] The invention relates to the technical field of static balancing machines, in particular to an air-suspension rotary frame of a static balancing machine and an air-suspension static balancing machine. Background technique [0002] In the field of national defense equipment technology research, there are many gyrostabilizing devices that require high-precision balance, such as photoelectric stabilization devices in guided missiles, control moment gyroscopes, seekers, etc., helicopter propeller blades, engine blades, etc. The static unbalance of the product is directly related to the working performance of the overall system. For missiles, technical indicators such as missile guidance accuracy, navigation accuracy, and hit accuracy will be affected by the static value parameters of the stabilized pointing device. For helicopters, the static balance adjustment of propeller blades is directly related to the flight safety of the product and stability. In ...

AI Technical Summary

Problems solved by technology

In the field of static balance parameter measurement of national defense products in my country, the installation and adjustment of a single axis system in the photoelectric stabilization device generally adopts a blade-supported rolling balance frame, and relies on empirical visual trimming. There is no effective measurement method for the hidden azimuth axis so far, which can realize spatial adjustment. There are very few measurements of the static balance parameters of the two-dimensional shaft system; after the control torque gyro is assembled, the cables on the rotor are wound, and the balance accuracy is very high. It is very difficult to measure and adjust the rotor eccentricity under actual working conditions, which belongs to the domestic Blank technology; the mass moment of the aircraft propeller is an important technical index, which needs to be measured, positioned and trimmed in production. The relevant domestic units still use the traditional balance method, which has low test accuracy and poor repeatability, and cannot meet the high-precision test and adjustment of related defense products. Therefore, static level adjustment technology is an important factor that affects and restricts the performance and safety of national defense equipment

[0003] In the field of static balance testing, the traditional knife-edge support frame, rotary support frame, and three-point support frame cannot achieve high-precision static balance adjustment due to their own friction and stress.
