Technical Field

[0001] This utility model relates to the technical field of rubber shock absorber bushing processing equipment, specifically a locking device for automotive polymer rubber shock absorber bushings. Background Technology

[0002] Most rubber bushings are composed of a single type of rubber, and their vibration absorption is unidirectional. When encountering multidirectional vibration absorption problems, hydraulic bushings can be used. Liquid is injected in one direction, and the vibration energy is absorbed through the liquid flow. Rubber bushings consist of inner and outer skeletons. After injection molding, the inner and outer skeletons are under tension, leading to high stress and potential fatigue. Therefore, after injection molding, the rubber bushings need to be locked and compressed. Existing locking devices for automotive polymer rubber shock absorber bushings have the following shortcomings: the locking operation is cumbersome, the locking force is difficult to control, and it affects the elimination of stress in the rubber bushings.
