종래에는 다양한 산업분야에서 사용되는 기계 및 결합장치에 있어서 부재와 부재를 서로 체결하기 위하여 각종의 나사를 사용하고 있으며, 나사결합을 위하여 부재의 표면에 탭 가공에 의해 나사구멍을 형성하고 있다.Background Art Conventionally, various machines are used to fasten a member and a member to each other in machines and coupling apparatuses used in various industrial fields, and screw holes are formed on the surface of the member by threading for screwing.

기계 및 결합장치의 정밀도가 점차적으로 중요시되고 있으며, 그에 따라 나사구멍의 직경, 깊이, 나사산의 치수 등의 정밀도 역시 중요시되고 있다. 그러므로, 나사구멍을 형성한 후에, 이들 나사구멍의 직경, 깊이, 나사산의 치수 등을 검사할 것이 요구되고 있으며, 이러한 요구에 부응하여 몇 가지의 검사방법 및 검사결합장치가 이용되고 있다.The precision of machines and coupling devices is becoming increasingly important. Therefore, the precision of screw hole diameter, depth, thread dimensions, etc. is also important. Therefore, after the formation of the screw holes, it is required to inspect the diameters, depths, dimensions of the screw threads, etc. of these screw holes, and several inspection methods and inspection coupling devices have been used in response to these requirements.

종래의 나사구멍 검사방법은, 탭 가공된 부재에 형성된 나사구멍에 검사자가 일일이 수작업으로 나사를 체결해 보면서 확인하는 것이었기 때문에, 번거로울 뿐만 아니라 시간이 많이 걸리고 인건비 등 검사비용이 많이 소요되는 것이었다. 더욱이 검사의 정확도 역시 낮은 것이었다.The conventional screw hole inspection method is not only cumbersome but time-consuming and labor costs such as labor costs because the inspector manually checks the screw holes in the threaded holes formed in the tabbed member. Moreover, the accuracy of the test was also low.

수작업으로 나사구멍을 검사하는 이외에 레이저를 이용하는 검사방법이 공지되어 있으며, 이 방법에 의하면 나사구멍의 직경 및 깊이는 비교적 정확하고 간단하게 검사하는 것이 가능하긴 하지만, 나사산의 치수 혹은 나사산 중간에 발생된 불량 등을 검사하는 것이 불가능하기 때문에, 정확도를 높이는 데에는 한계가 있는 것이었다.In addition to inspecting screw holes by hand, an inspection method using a laser is known. This method makes it possible to inspect the diameter and depth of screw holes relatively accurately and simply, Since it is impossible to check for defects, there was a limit to increasing the accuracy.
