Abstract

The present invention discloses a three-axial decoupling device with a pre-tightening structure. The three-axial decoupling device with the pre-tightening structure includes a slide rail, an X guide shaft, a Y guide shaft and a Z guide shaft; each guide shaft is arranged floatingly through a static pressure oil film layer formed by a corresponding first static pressure mechanism; and each first static pressure mechanism is provided with a pre-tightening screw, and one end of the pre-tightening screw is fixed to the first static pressure mechanism oppositely, and the other end of the pre-tightening screw is fixed to a static pressure mechanism at the same side or a static pressure mechanism at the other side oppositely. According to the three-axial decoupling device with the pre-tightening structure of the invention, a connection mode adopts the structural design of the pre-tightening screws. When the three-axial decoupling device is working, high-pressure oil is introduced into the three-axial decoupling device, high-pressure oil films are generated at two oil film layers; the pre-tightening forces of the pre-tightening screws can cancel tensile forces generated by the high-pressure oil films to the outside, and therefore, the gap of the oil film layers and the rigidity of the oil film layers can be ensured, and the operational stability and durability of the three-axial decoupling device can be improved. The invention also discloses a vibration table.

Description

technical field [0001] The invention relates to the field of test and measurement, in particular to a three-axis decoupling device and a vibrating table with a pre-tightening structure. Background technique [0002] At present, the development of uniaxial test system has gradually matured, but with the continuous development of science and technology, in order to improve the pass rate of products and reduce unnecessary losses caused by products in actual production, more and more scientific and technological fields need more The real simulation test environment is used to verify the product development. Then a three-axis vibration test system was produced. [0003] The Chinese utility model patent with the authorized notification number CN201218773Y discloses a three-axis vibration test device. The worktable and three vibration generators pass through one-way vibration-transmitting connectors, and each one-way vibration-transmitting connector can be placed on one of the thr...
