Description

Technical Field

[0001] The utility model relates to the technical field of casting surface treatment, in particular to a spherical casting surface treatment device. Background Art

[0002] Castings are metal shaped objects obtained by various casting methods. That is, 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 polishing, the resulting object has a certain shape, size and performance. Spherical castings are spherical castings.

[0003] After the casting is completed, burrs or particles will still remain on the surface. For safety and aesthetics, it is generally necessary to polish it to facilitate subsequent processing. When polishing spherical castings, most of them are fixed with a three-jaw chuck. The specific method is to place the spherical casting between the three jaws of the three-jaw chuck, and then the three jaws are synchronously moved close to complete the automatic centering and fixation of the spherical casting. Then, the surface is polished with a grinding wheel. However, after the spherical casting is fixed, its lower half is in the three-jaw chuck. Therefore, after the upper half is polished, it is necessary to loosen the fixation and turn the lower half over. However, most of the existing flipping steps are manual flipping, so the actual operation has certain risks, and manual flipping is also relatively inconvenient. Utility Model Content
