A positioning fixture for machining vertical cylindrical storage tanks

Abstract

This utility model relates to the field of vertical cylindrical storage tank processing technology, specifically a positioning fixture for processing vertical cylindrical storage tanks. It includes a processing table, a lifting mechanism slidably connected between the two sides of the processing table to support the tank wall, and a rotating mechanism slidably connected to the top surface of the processing table. Two rotating mechanisms are provided at both ends of the processing table, and each rotating mechanism includes a support plate slidably connected to the top surface of the processing table. In this utility model, by making multiple rubber wheels in close contact with the inner wall of the tank, and then rotating two fixed discs, the multiple rubber wheels can drive the tank wall to rotate on the lifting mechanism. This facilitates the grinding of the weld seams of the tank wall. Because both ends of the welded tank wall are restricted by multiple rubber wheels, the tank wall can be prevented from falling off the lifting mechanism during grinding. Furthermore, the lifting mechanism can prevent large deformations of some long and soft tank walls.
