Description

Technical Field

[0001] The utility model relates to the technical field of nitrogen spring processing, in particular to a positioning tool for nitrogen spring processing. Background Art

[0002] A nitrogen spring is a device that uses the compression and expansion of nitrogen to generate elastic force. It consists of a sealed container and a certain amount of nitrogen. When the nitrogen inside the container is subjected to external pressure, the nitrogen is compressed, the volume decreases, and the pressure increases. At this time, the nitrogen spring will generate a reaction force to offset the external pressure. By controlling the pressure of the nitrogen and the volume of the container, the expansion force of the spring can be controlled. Nitrogen springs are gradually replacing elastic elements such as springs, rubbers, and air cushions with their advantages of stable elastic force, small size, reliable working performance, and long service life, and are widely used in various fields. The processing of nitrogen springs requires the use of positioning tooling to ensure the quality and performance of nitrogen springs and improve processing efficiency and precision, so a positioning tooling for nitrogen spring processing will be used.
