Description

Technical Field

[0001] The utility model relates to the technical field of steel casting production, in particular to a grinding device for steel castings. Background Art

[0002] Steel castings refer to parts made of cast steel, which have similar properties to cast iron, but are stronger than cast iron. Steel castings are prone to defects such as pore defects and inaccurate angle positioning during the casting process, and the casing may break during long-term use. Due to the characteristics of steel castings, almost all industrial sectors need to use steel castings, and they are particularly widely used in ships and vehicles, construction machinery, engineering machinery, power station equipment, mining machinery and metallurgical equipment, aviation and aerospace equipment, oil wells and chemical equipment. Grinding devices are usually used in the production and processing of steel castings, which make the surface of steel castings smoother and flatter.

[0003] At present, the existing grinding devices for steel casting production are not suitable for steel castings of multiple sizes, have a small scope of use, are not easy to replace and disassemble the grinding tools, and have no protective structure and are easily damaged. They have great limitations and cannot meet the needs of actual use.

[0004] After searching, the existing patent: A grinding device for steel casting production (application number: CN202021048806.5) includes a workbench, a rotating shaft and a grinding disc. The first electric telescopic rod and the second electric telescopic rod are fixed at symmetrical positions on the workbench, and the upper ends of the first electric telescopic rod and the second electric telescopic rod are fixed with a clamping mechanism. The upper end of the workbench is fixed with a support rod, and the inner side of the support rod is fixed with an anti-collision mechanism. The lower end of the rotating shaft and the upper end of the grinding disc are respectively fixed with an upper gasket and a lower gasket, and nuts are fixed on the bolts fixed on the upper gasket and the lower gasket. The clamping mechanism can clamp steel castings of multiple sizes, and the application range is wide. Then, the rotating shaft and the grinding disc can be separated by removing the bolts and nuts, which is convenient for replacing the grinding disc. Finally, the anti-collision mechanism can prevent the grinding disc and the support rod from being damaged due to collision during horizontal movement. The utility model has a wide application range, anti-collision, easy to disassemble and replace abrasives, easy to operate and easy to promote.

[0005] Although the above patent has a wide range of applications, is collision-proof, easy to disassemble and replace molds, easy to operate and easy to promote, the grinding range of the device is small when in use, and the grinding device cannot be adjusted longitudinally, so that when the steel casting needs to be longitudinally ground, the user needs to manually adjust the position of the steel casting, which is time-consuming and labor-intensive and inconvenient for users to use. Therefore, it is necessary to invent a grinding device for steel castings to solve the above problems. Utility Model Content
