Balancer Auxiliary Angle Locator

Abstract

The invention discloses an auxiliary angle positioning instrument of a balancing machine, and relates to the technical field of rotor dynamic balance, the instrument comprises a front circular plate,a rear circular plate, a supporting frame, a supporting frame bottom plate, a laser emitter, a metal spring piece, a height adjusting nut and the like, wherein the front circular plate and the rear circular plate are arranged on a shaft, the middle is positioned by using a thrust bearing, the metal spring piece is divided into a horizontal part and an inclined part, the horizontal part is fixed onthe end surface of the front circular plate, close to one side of the rear circular plate, the top end of the inclined part is clamped in a groove of the rear circular plate for achieving reverse locking of the rear circular plate, the height adjusting nut is arranged at the lower end of a central cylindrical structure of the supporting frame bottom plate so as to achieve the up-and-down movementof the supporting frame; the laser emitter sleeves a horizontal rod at the top of a laser emitter bracket and the laser emitter can swing in a vertical plane so as to irradiate laser beams at the peripheral edge position of the rotor; the instrument can conveniently find the angle to be positioned of the rotor during correction, reduces the correction times and achieves the purpose of quickly correcting the rotor to a balance position.

Description

technical field [0001] The invention relates to the technical field of flat rotor dynamic balancing, in particular to an angle locator of a balancing machine, which is used to assist in determining the rotor angle in the balance rotor test, and is suitable for teaching and demonstration experiments, and assists in determining the quality of the rotor when the factory manufactures the rotor Correction of the position and other scenarios. Background technique [0002] The balance correction of the rotor is an important part of the engineering test technology. In the rotor dynamic balance test, the dynamic balancing machine can clearly show the angle of the unbalanced amount of the rotor to be tested. According to the result, the experimenter rotates the rotor to the corresponding angle. position for mass correction. In the laboratory, the rotor used for experimental teaching has a scale because of its small size, and the balancing machine can accurately position it after the ...

AI Technical Summary

Problems solved by technology

In the laboratory, the rotor used for experimental teaching has a scale because of its small size, and the balancing machine can accurately position it after the correction angle is given. However, in actual engineering, the rotor itself cannot be equipped with a scale, and the experimenter cannot accurately determine it. Its position, even if the scale is drawn on the rotor in advance, there will be measurement errors, only the approximate position can be determined, and each corrected position has a large error, so it needs to be corrected many times

In particular, when the diameter of the rotor to be tested is relatively large, it is more difficult to mark the accurate scale marks on it in advance, and if the rotors of different sizes are manually scaled in advance, it is an extremely time-consuming and labor-intensive work, which increases the labor force of the experimenters. workload
