Welding and positioning device for special-shaped parts in straight cylinder

Abstract

The invention discloses a welding locating device for special-shaped parts in a straight barrel and belongs to the technical field of welding locating equipment. The welding locating device for the special-shaped parts in the barrel aims at achieving the technical effects that locating is conducted precisely, assembling quality is high, and labor intensity is low. According to the technical scheme, the welding locating device comprises a flange, four locating rod assemblies, four supporting rod assemblies and four jacking rod assemblies; four key grooves are uniformly formed in the circular face of the flange in the circumferential direction; locating plates in the four locating rod assemblies are provided with keys, the keys are connected with the four key grooves in the flange correspondingly, jacking rods in the four jacking rod assemblies are arranged to be coaxial with locating rods in the four locating rod assemblies correspondingly, and supporting plates in the locating rod assemblies are arranged to be opposite to jacking blocks in the jacking rod assemblies; and the four supporting rod assemblies and a connection supporting plate are located among the four locating rod assemblies, and pressing plates in the four supporting rod assemblies face the supporting plates in the four locating rod assemblies and the jacking blocks in the four jacking rod assemblies correspondingly. The welding locating device is used for conducting welding locating on the parts in the barrel.

Description

technical field [0001] A welding positioning device for special-shaped parts inside a straight cylinder belongs to the technical field of welding positioning equipment, in particular to a welding positioning device for special-shaped parts. Background technique [0002] At present, in large-scale equipment manufacturing enterprises, the welding positioning requirements of the parts in the cylinder are relatively high, and the structure of the parts in the cylinder is complex. The welding positioning accuracy of the parts directly affects the welding quality of the parts and the accuracy of the parts in the subsequent process. assembly. At present, the welding positioning of the parts in the cylinder is generally carried out by hoisting the parts assembled with the installation block into the cylinder through the crane, after adjusting the position of the assembly parts, marking the assembly position of the parts in the cylinder, and completing the welding of the parts in the...
