High synchronization degree truss device for welding seal head of tank body

Abstract

The invention discloses a high synchronization degree truss device for welding a seal head of a tank body, and relates to the technical field of seal head machining equipment. The truss device comprises truss X-axis structures, truss Y-axis structures, a truss Z-axis structure, a truss R-axis structure and a handling fixture; the truss X-axis structures are oppositely arranged on the two sides of the truss Y-axis structures, and used for driving the truss Y-axis structures to horizontally move between the truss X-axis structures; and the truss Z-axis structure is arranged between the truss Y-axis structures, and used for driving the truss Z-axis structure to rise, fall and horizontally move between the truss Y-axis structures. The handling fixture is driven by the truss R-axis structure to do circular motion, and therefore the angle of the handling fixture is adjusted; and after the position of the handling fixture is adjusted, a to-be-machined seal head and a seal head assembly are clamped and fixed, and then handled. According to the truss device, a semicircular fixture is adjusted in multiple directions, and therefore the handling efficiency and the machining efficiency of the seal head and the seal head assembly are effectively improved.

Description

technical field [0001] The invention relates to the technical field of head processing equipment, in particular to a high-synchronization truss device for tank head welding. Background technique [0002] The head refers to the component used to close the end of the container to isolate the internal and external media, also known as the end cover, which is often used in tank trucks for material storage. The head is an indispensable part of pressure vessel equipment in many industries from petrochemical, atomic energy to food and pharmaceutical industries. Important parts, the role is to seal; [0003] According to the shape of the head surface, it can be divided into convex, conical, flat and combined shapes. The convex head refers to the head whose outer surface is convex, such as hemispherical, elliptical, dish-shaped and spherical without folding Head, etc. At present, the head welding equipment in the current technology relies on manual positioning, which is not accurate...
