Traction preventing device for sliding table of long-stroke horizontal vibrating table

Abstract

The invention relates to a traction preventing device for a sliding table of a long-stroke horizontal vibrating table, comprising a bearing vibrating table pipeline and a tracking platform which makes synchronous motion with the sliding table of the vibrating table. The pipeline is pressed on the tracking platform through a press block, passes through the tracking platform and is placed in a dragchain. The movable end of the drag chain is fixedly connected with the tracking platform. The tail end of the pipeline exposing outside the drag chain is connected with air supply equipment and a power supply power amplifier system. A displacement detection sensor for sensing the displacement of the sliding table is arranged on the sliding table. The tracking platform is erected on a synchronous belt and moves along a lead rail parallel to the sliding table under the drag of the synchronous belt, and the belt wheel of the synchronous belt is in linkage with a motor. The motor is controlled bya controller which can convert the displacement of the sliding table into the rotate speed of the motor so that the tracking platform and the sliding table synchronously move. The invention has the advantages of eliminating the traction action of the pipeline of the long-stroke horizontal vibrating table and reducing the degree of distortion of waveform output by the vibrating table.

Description

technical field [0001] The invention relates to an anti-pulling device for a sliding table of a long-stroke horizontal vibrating table. technical background [0002] With the rapid development of science and technology, the testing level of sensors is constantly developing towards the limit level. In the fields of aerospace, weapon guidance, earthquake prediction, superfinishing, oil exploration and other fields, people constantly put forward new requirements for the measurement frequency range of ultra-low frequency vibration measuring sensors. Velocity sensors with lower frequency below 0.01Hz and acceleration sensors with zero frequency response have been applied in various fields. The emergence of these sensors has put forward higher requirements for the ultra-low frequency measurement and calibration system. [0003] According to the provisions of the National Metrology Verification Regulations (JJG 134-2003, JJG 233-2008), the vibration sensor needs to be formally ca...
