High-precision dynamic balancing machine

Abstract

A high-precision dynamic balancing machine disclosed by the present invention comprises a base, the upper end surface of the base is provided with a left swing frame seat and a right swing frame seat which are equal in height and can move transversely, and the front side surfaces of the left swing frame seat and the right swing frame seat are symmetrically provided with a pair of non-contact displacement sensors. A pair of supporting seats is symmetrically arranged at the upper end of the left swing frame seat and the upper end of the right swing frame seat, a pair of vibration amplifying assemblies is symmetrically arranged in an inner cavity of the left swing frame seat and an inner cavity of the right swing frame seat, and an adjustable support with a photoelectric sensor is further arranged on the base. The device is simple in structure, adopts a split design, is convenient to manufacture and assemble, greatly reduces the research and development and production cost, is large in measurement precision and measurement range, and is especially suitable for the measurement of dynamic balance in a high-speed state.

Description

technical field [0001] The invention relates to the technical field of dynamic balancing machines, in particular to a high-precision dynamic balancing machine. Background technique [0002] At present, the number of users of dynamic balancing machines is relatively small, and it is a special equipment. In fact, it is necessary to carry out dynamic balance detection and elimination for objects running at high speed. Because the rotor will generate unbalanced amount during operation, the unbalanced amount will cause lateral vibration of the equipment, and this effect can only be detected and measured in the dynamic state of operation. The unbalance can be simplified to two sections selected arbitrarily, and only need to make corresponding corrections on these two surfaces. After measuring the phase angle and magnitude of the unbalanced quantity, either remove it directly, or increase the corresponding mass in its symmetrical direction to achieve dynamic balance. In order to...

AI Technical Summary

Problems solved by technology

In order to reduce the lateral vibration generated by the high-speed motor at high speed, a corresponding dynamic balancing machine is required for detection and correction, but the dynamic balancing machines purchased on the market do not meet the high-speed measurement range, and the speed is very high, which is small The amount of unbalance can also produce greater vibration, so a more accurate instrument is needed to measure
