Joint positioning device and method for compressed gas shell

Abstract

A joint positioning device and method for a compressed air shell, including a copper joint fixed on the compressed air shell; a mechanical detection device is arranged next to the copper joint, and the mechanical detection device is used to detect the position of the copper joint. Whether the free section of the bonnet is in a proper position after the fixed section of the bonnet is screwed on the upper end of the valve body. The copper joint includes a valve body, and the upper end of the valve body is threadedly connected with a bonnet, the bonnet is an inverted L-shaped structure, and the other side of the inverted L-shaped structure is used as a free section, and the fixed section of the bonnet of the copper joint When threaded with the upper end of the valve body, the fixed section of the bonnet needs to be screwed firmly to be screwed on the upper end of the valve body. It effectively avoids the need to judge the proper position of the free section of the bonnet under the moderate condition that the bonnet is screwed firmly in the prior art. The defects that make the structure cumbersome and complicated, require high environmental conditions, and cost are high.

Description

technical field [0001] The present invention relates to the technical field of compressed gas shell devices, and also relates to the technical field of joint positioning, in particular to a joint positioning device and method for compressed gas shells, and in particular to a copper joint positioning device and method for compressed gas shells. Background technique [0002] The compressed air casing is a part of the compressor used as a supercharger, and the existing compressor is a component that uses high-speed rotating blades in the engine to do work for the air to increase the air pressure. The front part of the compressor impeller blade is curved and called the guide wheel, which functions to guide the gas into the working impeller without impact and reduce the impact loss of the air flow. The compressor impeller of the small supercharger generally integrates the guide wheel and the working impeller. There is a diffuser at the outlet of the impeller of the compressor, s...

Problems solved by technology

[0004] In order to solve the above problems, the present invention provides a joint positioning device and method for the compressed air casing, which effectively avoids the need to judge the location of the free section of the bonnet under the moderate condition that the bonnet is tightened in the prior art. Only complex photoelectric detection and positioning devices can be used for suitable positions, and corresponding electronic components, power supplies and circuits must be introduced to make the structure cumbersome and complicated, with high requirements on environmental conditions and high costs.
