Abstract

The invention relates to a cylinder welding centering tool. The cylinder welding centering tool comprises a base, and is characterized in that the base is provided with an end cylinder mounting bracket and a middle cylinder mounting bracket for respectively mounting an end cylinder and a middle cylinder and guaranteeing the axis of the end cylinder and the axis of the middle cylinder to be positioned on the same vertical plane; and the end cylinder mounting bracket and the middle cylinder mounting bracket are horizontally arranged left and right. The cylinder welding centering tool further comprises a gap adjusting mechanism for adjusting a horizontal gap between the end cylinder mounting bracket and the middle cylinder mounting bracket. The cylinder welding centering tool firstly guarantees the axis of the end cylinder and the axis of the middle cylinder to be located on the same vertical plane, uses the gap adjusting mechanism for forming a proper riveting gap between the end cylinder and the middle cylinder during welding, and solves the problems of lower centering precision and lower efficiency caused by centering of the end cylinder and the middle cylinder through a traditional lineation mode.

Description

technical field

[0001] The invention relates to a centering tool for welding pressure vessels used in high-voltage electrical products, in particular to a cylinder welding centering tool. Background technique

[0002] The aluminum alloy welded cylinder used in high-voltage switchgear varies in length from 2 meters to 18 meters. In actual use, a conductive rod is installed inside and filled with high-purity SF6 gas as an insulating medium to ensure the insulation performance of the cylinder. , Usually aluminum alloy sheets are rolled and welded into a cylinder, and then aluminum alloy flanges are welded at both ends of the cylinder, or aluminum alloy spiral tubes are welded with aluminum alloy flanges. The traditional welding method is to place the middle cylinder and the end cylinder to be welded on the welding platform, relying on the contact surface of each cylinder and the welding platform to be centered on the same horizontal plane, for the middle cylinder and the end of...
