Embodiment Construction

[0029] In order to make the objectives, technical solutions and advantages of the present invention clearer, the present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0030] See Figure 1~Figure 12 As shown, in order to better weld the ring (not shown) and the profile frame (not shown), the present invention provides a tank bottom circumferential seam welding equipment, including positioning the ring and the profile The frame positioning jig 100, a motor (not shown) that drives the positioning jig 100 to rotate, and a welding device (not shown) for welding the ring and the circumferential seam of the profile frame. When in use, the ring and the profile frame are fixed on the positioning fixture 100, the positioning fixture 100 rotates according to a predetermined welding track, and the welding device performs circumferential seam welding from the outside.

[0031] See figure 1 , figure 2 with Picture 9 As shown...

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 welding automation of rocket tanks, in particular to a positioning fixture for positioning the ring and profile frame of the bottom of the tank, and a ring seam welding device for the bottom of the tank with the positioning fixture. Background technique [0002] The rocket body structure of the launch vehicle is mainly composed of propellant tank, riveting compartment, fairing and other parts. Among them, the propellant tank (storage tank for short) is a large-size, thin-walled, high-strength aluminum alloy welded structure. As the main bearing structure of the launch vehicle, it is the largest structural component in the rocket structure and affects the safety and safety of the launch vehicle. The key components of reliability account for 60% of the total mass of the rocket and 2 / 3 of the length of the full rocket. [0003] The storage box is assembled and welded by the bottom of the storage box and the tube section: th...
