Rigid reinforced multi-degree-of-freedom platform based on mechanic-electronic-hydraulic integration

Abstract

The invention discloses a rigid reinforced multi-degree-of-freedom platform based on mechanic-electronic-hydraulic integration. The platform is in a modular stacked layout. An X-axis platform 1 is fixedly connected with a foundation platform. The fixed end of an X-axis drive device 2 is fixed on the X-axis platform 1, and the moving end of the X-axis drive device 2 is connected with a Y-axis platform 3. The fixed end of a Y-axis drive device 4 is fixed on the Y-axis platform 3, and the moving end is connected with a Z-axis platform support plate 41. A Z-axis platform protection plate 11 is fixed around the surface of the Z-axis platform support plate 41. A Z-axis platform 10 is installed inside the space formed by the Z-axis platform protection plate 11 and the Z-axis platform support plate 41. The fixed end of a Z-axis lifting device 12 is installed on the Z-axis platform support plate 41, and the moving end is connected with the Z-axis platform 10. The platform can be accurately andautomatically positioned and locked in multiple degree-of-freedom directions, and is of high rigidity. The dynamic problem caused by a bench during the test of a high-power transmission mechanism canbe solved.

Problems solved by technology

[0002] Conventional transmission test benches have limitations in versatility and poor flexibility. The position of the power transmission mechanism cannot be adjusted arbitrarily according to different test requirements. The positioning accuracy is poor, the preparation for the test is long, and labor is time-consuming and labor-intensive.

In addition, the connection of high-power transmission mechanisms in mechanical equipment has high requirements for coaxiality, and the traditional transmission mechanism test platform is insufficient in the multi-degree-of-freedom adjustment process or cannot achieve multi-degree-of-freedom adjustment, so large motors and The one-time installation accuracy requirements for power transmission equipment such as gearboxes are too high, and the adjustment is not convenient enough

[0003] There are large vibrations in the test process of the existing high-power transmission mechanism, and a considerable part of the vibration is generated by the test platform itself, and the existing vibration reduction technology can only be used for the vibration of the test platform at a higher frequency. Attenuation cannot solve the problem of vibration control of the transmission mechanism in harsh mechanical environments, nor can it effectively attenuate the vibration level of the environment
