Description

Technical Field

[0001] The utility model relates to the technical field of shell processing, in particular to a thin-wall shell processing tool. Background Art

[0002] Tooling refers to the technological equipment in the production process, which is the general term for various tools used in the manufacturing process. Tooling includes fixtures, molds, measuring tools, etc. Tooling is an indispensable tool in the production and processing process. Different tooling fixtures are required for different products. Among them, when processing the thin-walled shells of methane pumps, oxygen pumps and other pumps, corresponding tooling is required for clamping and fixing.

[0003] After searching, Chinese patent CN216608209U discloses a thin-wall shell processing tool, which mainly uses a second electric telescopic rod to push the anti-slip pad to extend and retract outward, thereby effectively clamping and fixing the thin-wall shell.

[0004] By comparing with the existing technologies in related fields, it can be seen that when processing the inside of a thin-walled shell, in order to improve the processing efficiency, a tooling is directly used to clamp the thin-walled shell. Since the thin-walled shell has a certain length, when the thin-walled shell is directly clamped using a tooling fixture, the shell is easily deformed. During the processing, since the entire shell cannot be clamped, the front end of the thin-walled shell in the feed direction is very likely to shake, which affects the processing quality. Utility Model Content
