Abstract

본 발명은 공작기계에 있어서 베드, 컬럼, 테이블과 같은 대부품인 기계의 골조를 이루는 몸체의 구조에 관한 것으로, 종래에 있어서 주조 방식에 의하여 제조되는 몸체는 주철재료의 특성상 강도의 취약성이 있는 관계로 재료두께가 두꺼워질 수 밖에 없고 이에 따라 크기가 비대하여지고 중량이 많이 나가게 되는 문제점이 있었던바, 이를 해소하고자 본 발명은 베드나 컬럼 또는 테이블의 경우 판재를 이용한 구조의 외측프레임과 요철부, 하니콤형 또는 원형 단면형상의 내, 외측 보강부재를 용착고정형성하여 그 강도를 향상시키면서도 중량은 가볍게 할 수 있도록 하는 한편, 필요한 경우 내부에 덕트를 설치하여 내부공기의 순환이 가능하도록 하여 외부요인에 의한 국부열팽창 또는 수축현상을 배제시킬 수 있도록 함으로써 공작기계의 몸체제작에 적절하게 활용할 수 있는데 그 특징이 있다.The present invention relates to a structure of a body constituting a frame of a machine which is a large part such as a bed, a column, and a table in a machine tool. In the related art, a body manufactured by a casting method has a weakness in strength due to the characteristics of cast iron materials. As the material thickness of the furnace is inevitably thickened and accordingly, there is a problem in that the size is enlarged and the weight is increased. The inner and outer reinforcing members of the honeycomb type or circular cross-sectional shape are welded and fixed to improve the strength while reducing the weight, and if necessary, a duct is installed inside to allow the circulation of the internal air. Manufacture of body of machine tool by eliminating local thermal expansion or contraction There can be appropriately utilized its features.
