Abstract

The invention provides a stroke-variable precision moving coil for a vibrating table, and relates to the field of vibrating tables, the stroke-variable precision moving coil comprises a moving coil lower tabletop, a plurality of guide rods are fixedly connected to the top of the moving coil lower tabletop, a moving coil upper tabletop is fixedly connected to the tops of the guide rods, and a firstmoving coil is arranged in the middles of the guide rods; a plurality of fixing rods are fixedly connected to the outer side of the first moving coil, and the number of the fixing rods is the same asthat of the guide rods. According to the stroke-variable precision moving coil for the vibrating table, when the stroke-variable precision moving coil is usually used for a vibrating table with a common stroke, air in the first air bag and the second air bag is pumped out through the first micro air pump and the second micro air pump, the first air bag and the second air bag contract under the action of air pressure, and the first air bag drives the second moving coil to move upwards; and the second air bag drives the third moving coil to move downwards, so that the second moving coil and thethird moving coil are far away from the first moving coil and do not influence the first moving coil.

Description

technical field [0001] The invention relates to the technical field of vibrating tables, in particular to a variable-stroke precision moving coil for vibrating tables. Background technique [0002] At present, the maximum displacement peak-to-peak value of the electric vibration table for vibration or impact test is only 100mm. When it is necessary to do a large displacement vibration or impact test of more than 100mm, the ordinary electric vibration table cannot meet the requirements. For a vibrating table with a large displacement, it is necessary to increase the length of the driving coil of the moving coil to ensure that the coil of the moving coil is always in the working air gap during the movement, that is, to ensure that the effective number of turns of the coil remains unchanged. [0003] According to the Chinese patent No. CN201510874785.X, a long-stroke moving coil structure for an electric vibrating table is provided, the comparison document includes a moving co...
