When the contrast value is within the tolerance range, the selection unit 60 is a regular product and when the tolerance value is out of the tolerance range. Will be read as defective.

이때, 상기 검사된 축부재(100)가 불량품으로 판독될 경우에는 자체에 마련된 경고등(62)을 점등하거나, 스피커(63)를 통해 경고음을 발생시켜 작업자가 불량발생 여부를 신속히 인지하도록 한다.At this time, when the inspected shaft member 100 is read as a defective product, the warning lamp 62 provided thereon is turned on, or a warning sound is generated through the speaker 63 so that an operator can quickly recognize whether or not the defect has occurred.

한편, 본 실시예에 따른 검사장치(1)를 통해 검사되는 축부재(100)는 축부(110)에 기어부(120)가 형성된 구조인 점을 고려하여, 본 실시예에서는 상기 축부재(100)에 형성된 기어부(120)를 계측하는 전용의 검사구조를 마련하여, 기어부(120)의 치수 정밀도도 계측 가능하도록 하고 있다.On the other hand, considering that the shaft member 100 is inspected through the inspection device 1 according to the present embodiment has a structure in which the gear portion 120 is formed in the shaft portion 110, in the present embodiment the shaft member 100 The inspection structure dedicated to measuring the gear part 120 formed in () is provided, and the dimensional precision of the gear part 120 can also be measured.

이를 상술하자면, 본 실시예에서는 상기 축부재(100)의 기어부(120)가 형성 된 베이스부(10)의 일편에는 계측기어(43a)가 축 설치된 고정 브라켓(43)을 가이드(12)를 통해 진퇴구조로 설치하고, 상기 고정 브라켓(43)의 후미에는 감지봉(42a)의 진퇴를 통해 고정 브라켓(43)의 진퇴량을 감지하는 검사부재(42)를 설치하고 있다.In detail, in the present embodiment, the guide 12 includes a fixing bracket 43 in which a measuring gear 43a is axially mounted on one side of the base portion 10 on which the gear portion 120 of the shaft member 100 is formed. It is installed in a retracted structure through, the rear end of the fixing bracket 43 is provided with a test member 42 for detecting the amount of retraction of the fixed bracket 43 through the retreat of the sensing rod (42a).

바람직한 실시예를 보여주는 도면을 보면 상기 계측기어(43a)가 마련된 고정 브라켓(43)과 검사부재(42) 사이에는 스프링(43b)이 설치되어서, 상기 스프링(43b)의 탄발력에 의해 상기 고정 브라켓(43)에 축 설치된 계측기어(43a)는 축부재(100)의 기어부(120)에 밀착되어 안정되게 치합될 수 있도록 구성되어 있다.Referring to the drawings showing a preferred embodiment a spring (43b) is provided between the fixing bracket 43 and the inspection member 42 is provided with the measuring gear (43a), the fixing bracket by the elastic force of the spring (43b) The measuring gear 43a provided on the shaft 43 is configured to be in close contact with the gear portion 120 of the shaft member 100 and to be stably engaged.

따라서, 회동부(50)의 구동기어(52)가 축부재(100)의 기어부(120)와 치합되어 회전하면 상기 축부재(100)는 일방향으로 회전되며, 이때 도 5에서 보는 바와 같이 상기 축부재(100)의 기어부(120)와 치합된 계측기어(43a)도 일방향으로 회전하게 된다.Therefore, when the driving gear 52 of the rotation unit 50 is engaged with the gear unit 120 of the shaft member 100 and rotates, the shaft member 100 is rotated in one direction, as shown in FIG. The measuring gear 43a meshed with the gear part 120 of the shaft member 100 also rotates in one direction.

이 과정에서 축부재에 형성된 기어부(120)의 치수나 형상의 불량이 발생된 경우, 이와 치합하여 회전하는 계측기어(43a)의 요동이 발생되므로 상기 계측기어(43a)를 축 설치한 고정 브라켓(43)는 가이드(12)를 따라 진퇴가 이루어진다.In this process, when a defect in the dimension or shape of the gear unit 120 formed in the shaft member occurs, the shaking of the measuring gear 43a which rotates in conjunction with this occurs, so that the fixing bracket with the measuring gear 43a installed therein. 43 moves forward and backward along the guide 12.

이때, 상기 검사부재(42)는 감지봉(42a)을 통해 상기 축부재(100)와 치합하여 회전하는 계측기어(43a)를 축 설치한 고정 브라켓(43)의 진퇴량을 계측하고, 선별부(60)는 상기 계측기어(43a)의 진퇴량을 통해 생성된 계측값과 데이터 베이스에 사전 저장된 계측값을 대조하여 축부재(100)에 형성된 기어부(120)의 편심도와 치형과 피치폭을 포함하는 기어부의 치수 정밀도를 계측하도록 구성된다.At this time, the inspection member 42 measures the amount of retreat of the fixed bracket 43 in which the measuring gear 43a is rotated in engagement with the shaft member 100 through the sensing rod 42a, and the selection unit 60 checks the eccentricity, tooth shape, and pitch width of the gear unit 120 formed on the shaft member 100 by comparing the measured value generated through the advancement amount of the measuring gear 43a with the measured value pre-stored in the database. It is comprised so that the dimension precision of the gear part containing may be measured.

따라서, 본 실시예에 따른 축부재 검사장치(1)는, 축부재의 안정된 고정구조와, 안정된 축부재 전용의 검사구조를 통해 축부재의 치수 정밀도와 편심도를 포함하는 축부재의 전반적인 정밀도를 단시간에 계측할 수 있다.Therefore, the shaft member inspection apparatus 1 according to the present embodiment, through the stable fixing structure of the shaft member and the inspection structure dedicated to the stable shaft member, the overall precision of the shaft member including the dimensional accuracy and eccentricity of the shaft member It can measure in a short time.
