Description

Technical Field

[0001] The invention belongs to the field of tableware processing equipment and relates to a cambered surface polishing machine. Background Art

[0002] In the process of tableware forming, it needs to go through multiple processes such as forming, calendering, welding, grinding and polishing. In the process of polishing, multiple surfaces need to be polished. The grinding of the arc surface is the most difficult to achieve, because the trajectory of the arc surface to be polished is relatively complex. The concave arc surface of the spoon is a more difficult arc surface to grind. The polishing inside the spoon requires multiple steps. The inside of the spoon is a curved surface, which needs to be set according to the shape of the spoon. Moreover, the shape is not standardized and requires multi-axis simultaneous action to complete the polishing. At present, manual polishing is mostly used, which has high labor intensity and low efficiency. The quality of polishing is not uniform, and there are certain requirements on the level of the operator. If a six-axis robot is used for polishing, it can meet the requirements of the motion trajectory, but the procurement cost is too high, which greatly increases the operating cost of the enterprise.
