AI Technical Summary

Technical Problem

The existing welding process for forced-seal ball valves requires a large number of fixtures and positioning tools, and it is difficult to adapt to ball valves of different specifications, resulting in inconvenient welding and frequent product quality problems.

Method used

A mobile welding device was designed, including a symmetrically arranged positioning component and a platform. The positioning component is equipped with a positioning block and a limiting plate. The position of the positioning block is adjusted by a scale. Combined with a slide rail and a threaded rod, the pipe fitting is quickly positioned and supported. The pipe fitting is precisely positioned and rotated for welding through a drive component and an up-and-down moving component.

Benefits of technology

It enables rapid and precise positioning and welding of forced-seal ball valves, adapts to the processing needs of ball valves of different specifications, and improves welding efficiency and product quality.

Abstract

The application discloses a mobile electric welding device for processing a forced sealing ball valve, which comprises a support, another positioning assembly is arranged opposite to the top of the positioning assembly, the two positioning assemblies are symmetrically arranged, the positioning assembly comprises a platform, a through hole is formed through the platform, a positioning block is arranged through the through hole, a limiting plate is arranged on one side of the positioning block, at least one sliding bar penetrating through the limiting plate is fixed on the positioning block, the sliding bar is slidably connected with the hole formed in the limiting plate, a locking assembly matched with the sliding bar is further arranged on the limiting plate, the positioning block is in the shape of a circular truncated cone as a whole, the positioning block is composed of two arc surfaces and two planes, and scales are arranged on the planes; the positioning block is used for quickly positioning the pipe, after the inner diameter of the pipe is measured, the position of the positioning block is adjusted so that the scale value is consistent with the inner diameter of the pipe, at this time, the pipe is sleeved on the positioning block, and the positioning block can position the pipe, and the positioning is very convenient.
