[0001] The invention belongs to the field of testing instruments, and in particular relates to a manual armored bellows swing performance testing device. Background Art

[0002] In the production process of armored bellows, after welding and assembly, its swing flexibility needs to be tested preliminarily. The method used in the previous test process is to use a test fixture, then fix the bracket of the fixture on the table or the ground, and then use bolts to fix the lower flange of the armored bellows to the base, and then use another steel plate to connect the upper end of the armored bellows with bolts, and then grab the handle of the upper steel plate by hand to shake the bellows in the direction specified by the process regulations to detect its flexibility. In order to fix the armored bellows, 12 connection holes will be set on the upper and lower flanges. Therefore, 24 bolts need to be connected when installing using this method, which is troublesome to operate and the test efficiency is very low. It can be barely accepted for single-piece production, but it is very cumbersome for production with a certain batch.
