Abstract

The invention discloses an aero-engine assembly measuring system two-dimensional driving device based on plane orthogonal decoupling and belongs to the technical field of precision instruments and machinery. A tray is arranged between a base and a table top. A Y-direction guide block B fixedly connected to the tray is matched with a guide groove b1 in the tray in a contact mode, and a Y-direction guide block A is matched with a guide groove b2 in the tray in a contact mode to guide the tray to move along the Y-axis. A Y-direction motor drives the tray to move forwards along the Y-axis, and a Y-direction spring is compressed to provide restoring force for reverse movement of the tray along the Y-axis. An X-direction guide block A fixedly connected to the table top is matched with a guide groove b3 in the tray in a contact mode, and an X-direction guide block B is matched with a guide groove b4 in the tray in a contact mode to guide the tray to move along the X-axis. An X-direction motor drives the table top to move reversely along the X-axis, and an X-direction spring is compressed to provide restoring force for forward movement of the table top along the X-axis. By means of the aero-engine assembly measuring system two-dimensional driving device, the moving and positioning accuracy of an aero-engine assembly measuring system is improved, and the assembly accuracy and measurement efficiency of an engine are improved.

Description

technical field [0001] The invention belongs to the technical field of precision instruments and machinery, in particular to a two-dimensional drive device for an aero-engine assembly measurement system based on plane orthogonal decoupling. Background technique [0002] In recent years, as the advanced equipment manufacturing industry gradually develops towards precision and ultra-precision, especially the continuous improvement of aero-engine performance, the precision requirements for engine processing and assembly are getting higher and higher, especially in the pursuit of higher thrust-to-weight ratio. , the impact of engine vibration, noise and other factors caused by assembly errors on performance is gradually highlighted. This poses a severe challenge to the performance of the engine test equipment, and thus has higher requirements on the performance of the adjustment and positioning workbench used. [0003] In 2000, the friction-driven workbench developed by Samir M...
