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

Abstract

The invention provides an end socket inner wall grinding device for an aluminum alloy inner container of a high-pressure gas cylinder. The end socket inner wall grinding device and an outer circle grinding device are combined on one piece of equipment, so that the inner surface and the outer surface of the inner container can be ground respectively under one-time clamping; the outer circle grinding device can grind a pipe fitting with a rusted or scratched surface, so that the manufacturing efficiency and the appearance quality of a finished product are not influenced in the process of manufacturing the pipe fitting into the finished product; the end socket inner wall grinding device can find scratches or defects at different positions on the inner surface at any time through an industrial camera; through a connecting mechanism and a circuit which are arranged in an end socket inner wall grinding spindle, a grinding wheel can be driven by a high-speed motor to rotate at a high speed, so that high-speed surface grinding is achieved, and the grinding quality is guaranteed; and circumferential small-sector grinding is achieved, the problems of deep grooves, local over-grinding and the like caused by point-shaped grinding are effectively avoided, and the ground surface is smooth and continuous.

Description

technical field [0001] The invention belongs to the technical field of high-pressure vessels, and in particular relates to a head inner wall grinding device 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 ways for the mobile use of ...

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
