When the test result of the flatness of the housing base surface of the slewing ring support exceeds the technical requirements, the method of machining the housing base surface is usually used to ensure the flatness of the surface to meet the installation requirements of the slewing ring. This paper introduces the technology method of shim to ensure that the flatness of the housing base surface of the slewing ring on the housing base of the housing meets the technical requirements. A shim is added between the position to be adjusted on the house base surface of the slewing ring and the slewing ring on the house base of the housing structure to adjust the planarity of the house base surface of the upper slewing support on the house base of the housing structure to solve the problem that the planarity of the house base surface of the slewing ring is excessive due to welding deformation of the house base of the housing structure, reducing the production cost, shortening the production cycle of the product and improving the production efficiency.展开更多
