Pressure vessel end socket welding tool with locking and positioning functions

Abstract

The pressure vessel end socket welding tool with the locking and positioning functions comprises a base and a supporting mechanism, the base is connected with a supporting side plate, the supporting side plate is connected with a supporting mechanism used for supporting a vessel body, the supporting mechanism comprises a guide column and a supporting plate, the guide column is connected with an abutting mechanism supported by the supporting plate, and the supporting plate is connected with the abutting mechanism. The abutting mechanism comprises supporting columns and a second push rod, the supporting columns are connected with a driving mechanism used for driving the two supporting columns to get close to each other or get away from each other, the second push rod is used for driving the supporting mechanism to ascend, the supporting mechanism comprises a supporting disc and an ejection block, and the guiding columns are connected with a pressing mechanism used for pressing the port. The pressing mechanism comprises a push plate, a pressing plate, a first inclined rod and a second inclined rod. The push plate is used for driving the pressing plate to move towards the supporting plate. The stability of the pressure vessel end socket is improved, centering is achieved, a good foundation is provided for follow-up welding, and operation is flexible and coherent.

Description

technical field [0001] The invention relates to the technical field of pressure vessel head processing, in particular to a pressure vessel head welding tool with locking and positioning. 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 cap. The head of the cylindrical container is generally a rotary shell. According to the shape of the head surface, it can be divided into convex shape, conical shape, flat shape and combined shape. Convex heads refer to heads whose outer surface is convex, such as hemispherical, elliptical, dish-shaped and non-frilled spherical heads. Some gas cylinders use a combined bottom head with a convex face inward, which can not only ensure strength, but also meet the needs of safe use. The pressure vessel head needs to use welding tooling during processing to achieve the purpose of welding. [0003] When the existing pressure ves...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide a pressure vessel head welding tool with locking and positioning, which can improve the stability of the pressure vessel head, and realize the centering of the pressure vessel head, so as to provide a good foundation for subsequent welding. The advantage of flexible and coherent operation solves the need for multiple pressing equipment to fix the head, which is inconvenient to control multiple devices synchronously, resulting in signs of delay in the operation of different equipment, which may easily cause the head of the pressure vessel to be skewed, thereby affecting the follow-up homework problem
