Description

Constant-angle pressure-regulating type water tank R-angle polishing production line and polishing equipment Technical Field The invention relates to the technical field of water tank polishing, in particular to a constant-angle pressure-regulating type water tank R-angle polishing production line and polishing equipment. Background After the stainless steel water tank is welded and formed, rough polishing and fine polishing treatment are required to be carried out on the inner side edges of the stainless steel water tank so as to obtain a smooth surface and eliminate welding seams. Because the water tank has the characteristics of large size and light weight, and the four inner angles are required to be processed in a consistent way, the traditional manual polishing mode has the problems of low efficiency, high labor intensity and large quality fluctuation. Therefore, there is a clear need in the industry for a complete automated system that can achieve automatic loading, flipping, multiple-station continuous grinding and integrated dust collection. Currently, some sanding devices attempt to be partially automated by robotic arms or special machines, but these solutions often lack systemization. For example, the apparatus may only implement polishing at a single station without integrating the automatic positioning, multi-angle turning and inter-station transfer functions of the workpiece, resulting in an inconsistent production flow and limited degree of automation. Furthermore, even with an automated sanding unit, the prior art generally relies on preset fixed parameters to control the position or pressure of the sanding head, and does not take into account the continuous wearing effect of the sanding belt as a consumable. The thickness of the abrasive belt is gradually reduced in the operation process, so that the polishing radius is directly changed, and the equipment cannot sense and adjust the polishing radius in real time. Therefore, the prior art has double defects that firstly, a complete automatic production line special for polishing inner corners of a stainless steel water tank is lacked, so that a great deal of manual intervention is still required for carrying, overturning and connecting a plurality of working procedures, and the overall efficiency is restricted. Secondly, in a limited automatic polishing unit, polishing process parameters cannot be adjusted in a self-adaptive mode due to the lack of an abrasive belt abrasion compensation mechanism, and polishing quality is gradually deteriorated along with the extension of operation time. The two problems commonly cause poor stability in the polishing process, the consistency of products is difficult to ensure, and the requirements of modern mass production on high stability and high quality cannot be met.
