Description

Technical Field

[0001] The utility model relates to the technical field of polishing devices, in particular to a two-side polishing device for metal castings. Background Art

[0002] Metal castings are metal shaped objects obtained by various casting methods, that is, the smelted liquid metal is poured into a pre-prepared mold by pouring, injection, suction or other casting methods. After cooling and subsequent processing such as grinding, the resulting object has a certain shape, size and performance. After the metal casting is formed, its surface needs to be polished.

[0003] In the prior art, a Chinese patent with announcement number CN213946020U discloses a metal polishing device, which adopts the scheme of "including an operating table, both sides of the top of the operating table are provided with card slots, an inner side of the operating table is connected to a hydraulic cylinder by bolts, an inner side of the operating table away from the hydraulic cylinder is connected to a limit plate by bolts, a pushing piece is inserted into the inner side of the limit plate, a strong spring is welded to the outer wall of the pushing piece on one side of the limit plate, a side of the strong spring away from the limit plate is welded to the outer wall of the pushing piece, a top outer wall of the pushing piece away from the strong spring is connected to a moving box by bolts, one side of the top outer wall of the operating table is connected to a limit strip by bolts, and the moving box is slidably connected to the outer wall of the limit strip, and one side of the inner wall of the moving box is connected to a first motor by bolts". The hydraulic cylinder of this scheme pushes the pushing piece to one side, the strong spring is squeezed, the position of the moving box is adjusted, and the strong spring extends to pull the moving box back, so that the moving box can be moved back and forth, and the position of the metal part to be polished can be adjusted.

[0004] However, the above scheme still has some shortcomings. For example, when the polishing device is actually polishing a large plate-shaped metal casting, due to the large size of the plate-shaped metal component, it cannot be turned over in the limited space on the operating table, and thus both sides of the plate-shaped metal casting cannot be quickly polished. After polishing one side, it is necessary to manually turn it over and then polish the other side, which reduces the polishing efficiency.
