Description

전동기 하우징 내경 치수 측정장치{Motor Housing Inner Diameter Measuring Device}TECHNICAL FIELD [0001] The present invention relates to a motor housing inner diameter measuring device,

본 발명은 전동기 하우징 내경 치수 측정기에 관한 것으로서, 더 자세하게는 전동기 회전기기의 분해점검 시 하우징의 내경치수를 측정하기 위한 장치에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a motor housing inner diameter measuring device, and more particularly, to an apparatus for measuring an inner diameter dimension of a housing during disassembly and inspection of an electric motor rotating device.

일반적으로 전동기나 발전기등 회전기기의 분해점검시 하우징의 내륜치수를 측정하여 하우징의 불량여부 및 베어링과 공차를 계산한다.Generally, when the rotating equipment such as electric motor or generator is disassembled and checked, the inner ring dimension of the housing is measured, and the failure of the housing and the bearing and tolerance are calculated.

하지만 전동기 브라켓 중 오일둑(기둥)이 솟아있거나 장애물이 설치되어 있는 경우에는 내경을 측정할 수 없는 문제가 있었다.However, there was a problem that the inner diameter could not be measured when the oil dams (columns) were rising or obstacles were installed among the motor brackets.

따라서 장애물 또는 오일둑이 있는 경우에는 장애물 바깥 양쪽 측정 후 장애물 직경치수를 측정하여 분할 측정된 값을 합산하여 측정값을 표시하였다. 이러한 분할 측정은 3회 이상의 측정이 필요함으로 사용자의 인력 및 시간이 불필요하게 낭비하게 되고 합산된 측정값은 정확하지 않아 실제로 문제가 발생하였을 때 원인분석에 많은 어려움이 생기는 문제점이 발생하였다.Therefore, if there are obstacles or oil dams, we measure obstacle diameters after measuring both sides of the obstacle and sum the measured values by dividing measured values. This division measurement requires more than three measurements, which wastes manpower and time unnecessarily, and the summed measurement value is not accurate. Therefore, when the problem actually occurs, there arises a problem in causing the difficulty in the cause analysis.

본 발명의 실시 예는 이러한 종래기술의 문제점을 해결하기 위한 것으로서, 전동기 회전기기 내부에 형성된 기둥에 상관없이 하우징의 내경 치수를 측정할 수 있는 장치를 제공하고자 한다.An embodiment of the present invention is intended to solve the problems of the related art, and it is an object of the present invention to provide an apparatus capable of measuring an inner diameter dimension of a housing irrespective of a pole formed inside a motor rotating apparatus.

이러한 목적을 달성하기 위한 본 발명의 실시 예 전동기 하우징 내경 치수 측정장치는 장애물이 형성된 하우징의 내경을 측정하기 위한 몸체부와, 상기 몸체부의 일측에 결합되는 고정침과, 상기 고정침과 마주보게 상기 몸체부에 결합되는 마이크로미터로 구성된다.In order to achieve the above object, there is provided an apparatus for measuring an inner diameter of a motor housing, including a body for measuring an inner diameter of a housing having an obstacle formed therein, a fixed needle coupled to one side of the body, And a micrometer coupled to the body portion.

바람직하게, 몸체부는 원형의 구멍이 형성된 원형링 또는 반달 모양의 반달링인 것을 특징으로 한다. Preferably, the body portion is a circular ring having a circular hole or a half-moon-shaped half-ring.

바람직하게, 상기 몸체부는 구멍에 장애물이 위치하고 하우징의 내경을 측정하는 것을 특징으로 한다.Preferably, the body portion has an obstacle in the hole and measures the inner diameter of the housing.

본 발명 전동기 하우징 내경 치수 측정장치는 내부에 장애물이 있는 내경을 측정할 수 있으므로 내경 측정에 정확성 및 측정오차를 최소화하며 복수번 측정하여 분할 측정값을 합산하지 않아도 되므로 내경측정에 들어가는 인력, 시간 및 비용을 줄일 수 있다.Since the inner diameter measurement device of the motor housing of the present invention can measure the inner diameter with an obstacle therein, it is possible to minimize the accuracy and measurement error in the inner diameter measurement, and it is not necessary to sum the divided measurement values by a plurality of measurements. Cost can be reduced.
