Description

Technical Field

[0001] The utility model relates to the technical field of vibration table accessories, in particular to a vibration table dynamic coil suspension and guide mechanism. Background Art

[0002] In the vibration table structure, the dynamic coil is a key component that determines the performance index of the equipment. Its structure, shape and material determine the first-order resonance frequency of the dynamic coil. In order to ensure the stability of the dynamic coil movement, a dynamic coil suspension mechanism is usually installed between the frame of the vibration table and the dynamic coil. The dynamic coil suspension mechanism determines the system index of the vibration table and also has a guiding effect on the dynamic coil. However, the elastic components of the existing dynamic coil suspension mechanism of the vibration table are prone to large deformation after long-term use, which affects the stability of the dynamic coil operation and may even break in severe cases. Therefore, a vibration table dynamic coil suspension and guiding mechanism is developed. Utility Model Content
