Description

Technical Field

[0001] The invention relates to the technical field of installation tools, in particular to an exhaust bellows installation tool. Background Art

[0002] There are multiple expansion joints on the exhaust pipe of a diesel engine. The intervals between the exhaust pipes are fixed. Since the expansion joints are elastic, the length of the expansion joints is larger than the intervals between the exhaust pipes in the original state, which makes installation more difficult.

[0003] With the increase in the diesel engine market, the current installation method is inefficient and cannot meet production requirements. The existing diesel engine exhaust bellows have the following disadvantages when installed: 1. The length of the expansion joint cannot be controlled during installation; 2. The expansion joint cannot be quickly installed between the two exhaust pipes, and the work efficiency is low. Therefore, it is necessary to design an exhaust bellows installation tool, which is mainly suitable for compressing and fixing the length of the bellows when installing it to prevent it from offsetting, etc., so as to facilitate installation and improve work efficiency. For this purpose, an exhaust bellows installation tool is proposed. Summary of the invention
