Description

Technical Field

[0001] The utility model relates to the technical field of polishing devices, in particular to a volute outer surface polishing device. Background Art

[0002] The volute is the abbreviation of the volute water diversion chamber. In order to ensure that the water can be evenly supplied to the water diversion mechanism, the cross-section of the volute is gradually reduced. At the same time, the volute can form a necessary ring in front of the water diversion mechanism to reduce the working intensity of the water diversion mechanism. The volute is usually cast as a whole during the production process, and the working surface is relatively rough, so it will have a greater impact on the efficiency of the unit. In order to improve the quality level of the component surface, the inner surface of the volute needs to be polished;

[0003] However, in the existing technology, the commonly used method is to grind the volute manually. Since the inner wall of the volute is a curved surface, it is difficult for workers to control the strength and direction during grinding, which requires high operation of the workers. In addition, manual polishing is very difficult, which may lead to insufficient polishing and reduce work efficiency. In addition, dust is easily generated during the grinding and polishing process of the volute, which may cause harm to the human body, thereby failing to achieve the best use effect.
