Abstract

The invention provides a support device for the moving coil of a vibrating table and relates to a moving coil of a vibrating table. The device is used for supporting a moving coil of a large-displacement vibrating table. The device comprises a piston cylinder arranged inside the vibrating table, a piston arranged inside the piston cylinder, and a piston rod. One end of the piston cylinder is in communication with the atmospheric pressure, and the other end of the piston cylinder is in communication with a compressed air supply device. The piston is capable of conducting the reciprocating motion in a vibration direction preset by the moving coil inside the piston cylinder. One end of the piston rod is connected with the bearing platform of the moving coil. The other end of the piston rod passes through one end of the piston cylinder to be connected with the piston. Based on the support device, not only the travel requirement of the moving coil of the large-displacement vibrating table can be met, but also the bearing capacity for the installation of the moving coil and test pieces is provided.

Description

technical field [0001] The invention relates to a vibrating table moving coil, in particular to a supporting device for a vibrating table moving coil. Background technique [0002] At present, the bearing of the moving coil of the electric vibrating table mainly adopts the air spring installed in the center of the table body, and the purpose of carrying the moving coil is achieved by filling the inside of the air spring with compressed air. At the same time, the effective stroke of the moving coil also depends on the elongation and compression of the air spring. [0003] Since the design of the air spring not only needs to meet the axial load, but also needs to consider its own radial stiffness, the elongation of the air spring cannot be too large, and for the vibration table with large displacement, only the way of superimposing the air spring can be adopted. However, after multiple air springs are superimposed, while the axial force is loaded, the radial direction will be...
