A penetrating tank inner wall flexible polishing device

Abstract

The invention discloses a stretching-in type tank inner wall flexible polishing device. The stretching-in type tank inner wall flexible polishing device comprises a supporting base and a first motor arranged on the supporting base. The first motor drives a main rotating shaft to rotate. The outer ring of the main rotating shaft is sleeved with a sliding piece capable of sliding back and forth in the axis direction of the main rotating shaft. In the axial direction of the main rotating shaft, at least two first connecting rods are arranged at the tail end of the sliding piece in the circumferential direction. Second connecting rods are arranged at the tail end of the main rotating shaft in the circumferential direction, and the number of the first connecting rods is equal to the number of the second connecting rods. The tail end of each second connecting rod is connected with a flexible polishing head. The first connecting rods adjust the unfolding angle of the second connecting rods, meanwhile, the second connecting rods are driven by the main rotating shaft to rotate, and polishing on the inner walls of tanks with different diameters is achieved.

Description

technical field [0001] The invention relates to the field of tank inner wall polishing, in particular to welded tank parts with varying diameters. Background technique [0002] The traditional hand-held polishing machine is only suitable for polishing the outer surface with a simple structure, which requires high technical level of the operator, and the consistency of the polished surface quality cannot meet the requirements. At present, most of the inner wall polishing machines on the market are only suitable for polishing tank parts with a fixed diameter, and it is difficult to process tank parts with varying diameters. The cost of polishing the inner wall of such tank parts with existing devices is high. Contents of the invention [0003] Aiming at the deficiencies of the above-mentioned prior art, a probe-type flexible polishing device for the inner wall of the tank is designed. The polishing diameter can be adjusted, and it can be probed into the smaller opening end t...
