Abstract

The invention relates to a spherical metal shell assembling method and a detection tool special for implementing the same. The spherical metal shell assembling method includes 1) feeding to obtain a spherical-crown shell and groups of spherical bend plates, and assembling each group of spherical bend plates end to end to surround one layer of spherical rings; 2) arranging the spherical-crown shell on a support pipe column and detecting the spherical-crown shell by the detection tool to enable the upper edges of the spherical-crown shell to be on the same plane and fixed; 3) sequentially arranging the spherical bend plates in the first group corresponding to the first layer of spherical rings at the corresponding positions arranged at the upper edges of the spherical-crown shell, detecting, adjusting and fixing by the detection tool, and finally, enabling the upper edges of the spherical bend plates to be on the same circumference line; 4) adjusting angle of a detection arm, sequentially assembling until a spherical shell not larger than a hemisphere is assembled. By detecting and adjusting while fixing and assembling, the detection tool is simple in structure and convenient to operate, roundness of the sphere and assembly accuracy and quality are guaranteed.

Description

technical field

[0001] The invention relates to the manufacture of a metal spherical shell, in particular to an assembly method of the metal spherical shell and a detection tool specially used for implementing the method. Background technique

[0002] In the UHV DC transmission system, due to the very high operating voltage and the superposition of various transient overvoltages, in order to avoid discharge, a large number of shielding balls are used in the system to make the electric field of the entire transmission system uniform. The balls are all thin-walled parts with a maximum diameter of up to 3 meters. Such thin-walled metal balls are generally obtained by stamping with large molds or spinning with large-scale tooling, and the cost is too high; the background of the description of the Chinese patent application "Method for making high-precision thin-walled metal balls" with the publication number CN 1714994A A method for making thin-walled metal balls is disclosed i...
