Description

Cylindrical lightweight aluminum casting surface treatment device Technical Field The invention relates to the technical field of aluminum casting surface treatment, in particular to a cylindrical lightweight aluminum casting surface treatment device. Background Under the background of the rapid development of the intelligent manufacturing equipment industry, the cylindrical light aluminum casting is widely applied to a plurality of fields of automobiles, aerospace, electronic equipment and the like by virtue of the advantages of light weight, good strength adaptability and high forming efficiency. The molding of the castings depends on a die casting or gravity casting process, and in the production process, the mold is designed to be of a detachable structure, so that the molded castings are conveniently demolded, and parting lines can be naturally formed on the surfaces of the castings at the joint positions of the molds during mold closing. Continuous flash tends to remain at the parting line due to limitations in the flow characteristics of molten metal in the mold, cooling rate differences, and mold closing accuracy. These flash not only affect the appearance cleanliness of the castings, but also interfere with the subsequent assembly accuracy and may even fall off during use to cause hidden danger, so the removal of parting line flash is an indispensable key process in the surface treatment process of cylindrical lightweight aluminum castings, and it is usually required to thoroughly remove the flash through special polishing operation to ensure the quality and the service performance of the castings. The existing cylindrical light aluminum casting surface treatment device has a plurality of obvious defects, and is difficult to meet the production requirements of large scale and high precision. Most of the existing devices need to manually take out the molded castings from the bottom die, and then manually polish the castings, so that the operation process is tedious, time-consuming and labor-consuming. When polishing, the parting line is difficult to be aligned by manpower for linear polishing, polishing deviation is easy to appear, other surfaces of the casting are polished by mistake, the surfaces of the casting are scratched and damaged, and the appearance and the structural integrity of the casting are affected. Meanwhile, the consistency of manual operation is extremely poor, polishing forces and angles of different operators are different, so that the burr removing effect is uneven, part of casting burrs are not thoroughly removed, excessive polishing is caused in part of casting burrs, the subsequent repairing process is increased, the production efficiency is reduced, and the requirements of the intelligent manufacturing equipment industry on efficient and accurate production cannot be met. Disclosure of Invention The invention aims to provide a cylindrical light aluminum casting surface treatment device, which aims to solve the problems that the existing cylindrical light aluminum casting surface treatment device provided in the background technology needs to manually take an aluminum casting out of a bottom die and then manually polish the aluminum casting, is complex in operation and low in efficiency, is difficult to accurately align a parting line by manual polishing, is easy to generate deviation and is mistakenly polished to other surfaces of the casting, surface scratches and damages are caused, meanwhile, the force and angles of different operators are different, the burr removing effect is uneven, and incomplete or excessive polishing is caused.
