The general shape of different porcelain insulators is almost the same, and the main difference lies in that the umbrella skirt of different porcelain insulators is different, can divide into bowl form and pie form generally, because the umbrella skirt of porcelain insulator and cylinder junction are circular-arc and the interval between the umbrella skirt of the porcelain insulator of present high voltage transmission line is less, if can not fully polish the fine lines and the crack of umbrella skirt and cylinder before firing, can lead to porcelain insulator intensity insufficient after firing, and current grinding device hardly fully polishes between the porcelain insulator umbrella skirt, especially the bowl form porcelain insulator of high voltage transmission line still mainly carries out with manual polishing mode at present, current grinding device mainly has following problems in the use:
1. the existing polishing head of the polishing device can only polish porcelain insulators with one fixed size, and is difficult to solve the problem that the polishing head is not strong in applicability of the polishing device because of polishing of porcelain insulators with various types.
2. Most of the existing polishing devices belong to traditional polishing devices, the polishing blocks or the polishing tool bits are adopted for polishing, the dried porcelain insulator is not fired, the surface strength of the porcelain insulator is far enough to be insufficient for polishing by the polishing blocks or the polishing tool bits, the polishing of fine lines and cracks can be insufficient by the polishing blocks or the polishing tool bits, damage to the porcelain insulator can be caused, and the polishing efficiency of the polishing device adopting the polishing blocks or the polishing tool bits is not high enough.
3.

4. The contact pressure of the polishing head and the polished porcelain insulator cannot be detected and controlled by the existing polishing device, insufficient polishing can be caused due to the fact that the contact pressure is too small, damage to the porcelain insulator is likely to be caused due to the fact that the porcelain insulator is too large, the porcelain insulator is different in size due to the fact that the porcelain insulator is different in size, polishing pressure which can be born by the porcelain insulator is also different, and damage to an umbrella skirt and a cylinder of the porcelain insulator can be caused if the polishing pressure cannot be dynamically controlled in the polishing process.
5. The existing polishing device does not achieve simple replacement of the consumable material of the polishing head, the existing polishing device adopting the polishing belt mode is complex in replacement of the polishing belt, the polishing device adopting the polishing block and the polishing tool bit needs to detach and replace the whole polishing head when being replaced, and insufficient installation and tail end precision of the device are easily caused in the process of disassembly and assembly.
