When in use, the mounting seat 10 is fixed on an external fixing part, the movable end assembly 30 is connected to an external power mechanism, and the external fixing part and the external power mechanism can be different parts of the same device or can be two different devices. The moving end assembly 30 moves in the radial direction of the inner chamber 11 under the external force provided by the external power mechanism, so that the moving end assembly 30 abuts against the annular elastic supporting device 200 accommodated in the inner chamber 11 and loads the annular elastic supporting device 200 or separates the moving end assembly 30 abutting against the annular elastic supporting device 200 from the annular elastic supporting device 200.
By adopting the technical scheme, the installation seat 10 is arranged for installing and fixing the annular elastic supporting device 200; by arranging the fixed connecting piece 20, the fixed connecting piece 20 is connected to an external fixed part, so that the mounting seat 10 is fixed on the external fixed part, and the movement of the mounting seat 10 to drive the annular elastic supporting device 200 to move during the detection of the annular elastic supporting device 200 is avoided; by providing the moving end assembly 30, a part of the moving end assembly 30 is positioned in the inner cavity 11 and moves in the radial direction of the inner cavity 11 under the driving of an external force, so that the moving end assembly 30 can be abutted against the annular elastic supporting device 200 accommodated in the inner cavity 11 to load the annular elastic supporting device 200 or the abutted moving end assembly 30 can be separated from the annular elastic supporting device 200 to release the load on the annular elastic supporting device 200.
When the movable end assembly 30 moves along the radial direction of the inner cavity 11 in the direction away from the central axis M of the inner cavity 11 under the action of external force, the movable end assembly 30 and the annular elastic supporting device 200 gradually change from a non-contact state to an abutting state, and when the movable end assembly 30 is in the abutting state, the movable end assembly 30 loads the annular elastic supporting device 200, and the annular elastic supporting device 200 deforms; when the movable end assembly 30 and the annular elastic supporting device 200 are in the abutting state, the movable end assembly 30 moves along the radial direction of the inner cavity 11 towards the direction approaching the central axis M of the inner cavity 11 under the action of external force, the movable end assembly 30 and the annular elastic supporting device 200 are gradually changed from the abutting state to the non-contact state, and when the movable end assembly 30 and the annular elastic supporting device 200 are in the non-contact state, the annular elastic supporting device 200 can be rotated to change the abutting position of the annular elastic supporting device 200 and the movable end assembly 30.
As an implementation manner, the tooling 100 provided in this embodiment is at least used for performing life detection on the annular elastic supporting device 200. In a specific application, when the life test is performed on the annular elastic supporting device 200, the movable end assembly 30 and the annular elastic supporting device 200 are repeatedly changed between a non-contact state and an abutting state, and external forces with different magnitudes are applied to deform the annular elastic supporting device 200 to different degrees. In addition, the size of the annular elastic supporting device 200 such as the squirrel cage elastic supporting device to be tested has a certain range, and the installation base 10 with proper size is arranged, so that the installation base 10 can accommodate the annular elastic supporting device 200 with the corresponding size range to be tested, thereby the tool 100 has universality.

As one embodiment, the annular spring support apparatus 200 includes, but is not limited to, a squirrel cage spring support or squirrel cage spring test piece 50. In particular applications, by testing the life of the annular elastomeric support device 200, the annular elastomeric support device 200 has been damaged and cannot be reused.

By arranging the moving member 31 and the annular elastic supporting device 200 at intervals along the axial direction of the inner cavity 11, the moving member 31 is prevented from contacting the annular elastic supporting device 200 when the moving end assembly 30 is driven by external force to move along the radial direction of the inner cavity 11, so that the detection accuracy is improved.
