End socket inner and outer wall grinding device for high-pressure gas cylinder aluminum alloy inner container

Abstract

The invention provides an end socket inner wall and outer wall grinding device for a high-pressure gas cylinder aluminum alloy inner container. The end socket inner wall and outer wall grinding devicecomprises a rack, and further comprises a main shaft mechanism, a first centering supporting mechanism, an outer circle grinding mechanism, a second centering supporting mechanism and an end socket inner wall grinding mechanism which are arranged on the rack in sequence. According to the device, grinding of the inner wall of an end socket and grinding of the outer circle of the end socket are combined on one piece of equipment, and the linear section and the curved section of the inner container can be continuously or separately ground under one-time clamping; and the inner wall of the linerend socket can be continuously or locally ground under one-time clamping. The outer circle grinding part in the device can grind the inner container with the bumped or scratched surface, and the end socket inner wall grinding part can find scratches or defects on the inner surfaces of different positions at any time; and high-speed grinding of the inner surface of the inner container end socket isachieved, and the grinding quality is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of high-pressure vessels, and in particular relates to a grinding device for inner and outer walls of a head used for an aluminum alloy inner tank of a high-pressure gas cylinder. Background technique [0002] High-pressure gas cylinders have been widely used in various industries of the national economy such as industrial and mining production, construction, transportation, ocean, aviation, medical treatment, and military affairs. The capacity of the high-pressure gas cylinder, the thickness of the bottle wall, the manufacturing process and the material all affect the performance of the high-pressure gas cylinder. Natural gas and hydrogen are clean energy sources that are being developed and widely used around the world. The storage and transportation of 20-35MP high-pressure gas cylinders and the use of compressed natural gas (CNG), compressed hydrogen and other compressed industrial gases are the main wa...

AI Technical Summary

Problems solved by technology

[0010] At present, there is no special grinding equipment for the inner and outer walls of the aluminum alloy liner head. Traditional grinders cannot continuously grind the outer surface of gas cylinders with ellipsoidal, butterfly, and spherical heads; Grinding treatment of the inner surface of the head section
