Abstract

The invention provides a positioning fixture for positioning a circular ring and a section frame at the bottom of a storage case. The positioning fixture comprises a base, a mould fixed on the base and used for positioning the circular ring and the section frame from the inner side, a first pressing assembly used for pressing the circular ring from the outer side and a second pressing assembly used for pressing the section frame; the first pressing assembly comprises a first pressing ring sleeving the circular ring from the outer side and a first pressing mechanism acting on the first pressing ring; the second pressing assembly comprises a second pressing ring sleeving the section frame from the outer side, a second pressing mechanism acting on the second pressing ring, and a third pressing mechanism used for pressing the section frame inwards from the outer side; the first pressing mechanism, the second pressing mechanism and the third pressing mechanism are fixed on the base and positioned on the outer side of the mould. The positioning fixture has good positioning effect on the circular ring and the section frame, cannot affect welding, and can provide guarantee for achieving high-quality welding.

Description

technical field [0001] The invention relates to the field of rocket tank welding automation, in particular to a positioning fixture for positioning a circular ring at the bottom of a tank and a profile frame, and a welding device for circular seam at the bottom of a tank with the positioning fixture. Background technique [0002] The rocket body structure of the launch vehicle is mainly composed of propellant tanks, riveted compartments, fairings and other parts. Among them, the propellant tank (referred to as the tank) is a large-scale, thin-walled, high-strength aluminum alloy welded structure. As the main load-bearing structure of the launch vehicle, it is the largest structural component in the rocket body structure and affects the safety and security of the launch vehicle. The key component of reliability accounts for 60% of the total mass of the rocket and 2 / 3 of the total length of the rocket. [0003] The storage tank is assembled and welded by the bottom of the sto...
