Description

TECHNICAL FIELD

[0001] The utility model relates to metal processing technical field more specifically, the utility model relates to a kind of polishing device for metal casting finish machining. BACKGROUND

[0002] During the manufacturing process of metal casting, its surface is often rough after casting, cooling and other processes, which will affect the performance and aesthetics of the casting. Therefore, it is necessary to polish the metal casting to optimize its surface quality and improve its performance.

[0003] The existing polishing device usually relies on the rotation and friction of the abrasive and the casting to achieve the polishing effect. However, since the weight of the casting is much greater than that of the abrasive, and the rotation axis remains unchanged, the parts will move closer to the inner wall of the polishing pot under the action of centrifugal force, so the side of the casting close to the inner wall of the polishing pot cannot be effectively polished.

[0004] According to the search, the polishing device for metal casting finish machining disclosed in the patent No. CN222038098U uses a motor to drive the polishing pot to rotate while revolving. Since the farthest point between the pot body and the revolving axis is always changing, the casting will not gradually move closer to the inner wall of the pot body due to centrifugal force, but will move around inside the pot body, achieving better polishing effect.

[0005] However, when cleaning and replacing the abrasive, the device needs to be disassembled, which is cumbersome and may not be properly installed, affecting the subsequent use of the device. UTILITY MODEL CONTENTS
