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 are parts made from cast steel. Made from molten steel through a casting process, they possess high strength and toughness, capable of withstanding heavy loads. They are widely used in machinery manufacturing, construction engineering, and other fields, providing reliable support and key components for various equipment and structures, playing a vital role in industrial production.

[0003] During the production process, steel castings require polishing to remove impurities such as scale and sand from the casting, resulting in a smooth surface. This improves dimensional accuracy and ensures smooth assembly with other components. This process also enhances the casting's aesthetics and corrosion resistance, extending its service life and meeting the high standards required of steel castings across various industries.

For some steel castings, the grinding surface area is large, which makes it impossible to complete the grinding work of the entire grinding surface at one time. In order to grind different positions of the grinding surface of the steel casting, the operation of disassembling and fixing the steel casting has to be repeated, which is very inconvenient.

The internal meshing of the synchronous belt 17 is provided with a driven pulley 16. The driven pulley 16 is fixedly connected to the first support shaft 8. The rotation of the second support shaft 6 drives the driving pulley 18 to rotate. The rotation of 18 drives the synchronous belt 17 to rotate, the rotation of the synchronous belt 17 drives the driven pulley 16 to rotate, and the rotation of the driven pulley 16 drives the first support shaft 8 to rotate, so that the function of grinding the rotating grinding wheel 7 and the function of moving the cast steel part back and forth are driven by the same drive unit, which improves the integration between the functions. The surface of the moving block 14 is provided with a clamping assembly, and the clamping assembly includes a telescopic cylinder 20 fixedly arranged at the bottom of the moving block 14. The number of the telescopic cylinders 20 is two, and the two telescopic cylinders 20 are symmetrically distributed. The two telescopic cylinders 20 improve the stability of the up and down movement of the mounting frame 19. The output end of the telescopic cylinder 20 passes through the moving block 14 and extends to the top of the moving block 14 where a mounting frame 19 is fixed. The internal fixed arrangement of the mounting frame 19 There is an electric push rod 21, and the extended end of the electric push rod 21 is fixedly provided with a clamping plate 22. There are two clamping plates 22, and the two clamping plates 22 are symmetrically distributed. The steel casting is placed on the mounting frame 19, and the extended ends of the two electric push rods 21 are extended so that the two clamping plates 22 are close to each other to clamp the steel casting. The telescopic cylinder 20 is driven to extend the output end so that the mounting frame 19 moves upward. The mounting frame 19 moves upward through the electric push rod 21 and the clamping plate 22 so that the steel casting moves upward and contacts the grinding wheel 7 to fix the steel casting and prevent the steel casting from shaking during grinding.

The rotation of the second support shaft 6 drives the grinding wheel 7 to rotate to grind the surface of the steel casting. At the same time, the rotation of the second support shaft 6 drives the disc 9 to rotate through the transmission assembly. The rotation of the disc 9 causes the first connecting rod 10 and the first connecting shaft 11 to rotate, and then causes the second connecting rod 12 to rotate on the first connecting shaft 11 and the second connecting shaft 13, thereby driving the moving block 14 to move back and forth. The movement of the moving block 14 back and forth causes the steel casting to move back and forth, and shortening the extended end of one electric push rod 21 and extending the extended end of the other electric push rod 21 can make the steel casting move left and right, so that the grinding wheel 7 grinds different positions of the grinding surface of the steel casting. After fixing the steel casting, the device can move the position of the steel casting to prevent the grinding wheel 7 from being unable to complete the grinding work of the grinding surface of the steel casting with a larger area at one time, thereby avoiding repeated fixing of the steel casting and improving the convenience of the device.
