Abstract

The invention provides a follow-up-error-free high-rigidity rotating two-dimensional adjusting and positioning device, and belongs to the technical field of precision instruments and machinery. According to the four-point positioning type two-dimensional adjusting and positioning device based on a restoring force constant structure, a support column A and an X-axis height adjusting device are distributed along an X axis, a support column B and a Y-axis height adjusting device are distributed along a Y axis, and the X axis and the Y axis are orthogonal. The device drives a motor to forwards rotating when the inclination of the device adjusted around the Y axis, a millesimal screw drives a workbench top to forwards rotate around the Y axis so as to drive the motor to rotate reversely, the millesimal screw transmits the drive force to a fastening connection block through a pre-tightened disc spring to drive the workbench top to rotate reversely around the Y axis. When the inclination of the device is adjusted around the X axis, the inclination adjusting mode of the Y-axis height adjusting device and the inclination adjusting mode of the X-axis height adjusting device are the same. The rotating two-dimensional adjusting and positioning device is used for aircraft engine assembling and meanwhile is high in accuracy and high in rigidity and has the high bearing feature.

Description

technical field [0001] The invention belongs to the technical field of precision instruments and machinery, in particular to a high-rigidity rotating two-dimensional adjustment and positioning device without follow-up error. 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. , due to the impact of engine vibration, noise and other factors caused by assembly errors on performance, it has gradually become prominent, which poses a severe challenge to the performance of the engine test equipment, and thus has a higher impact on the performance of the adjustment and positioning workbench used. Requirements, for the processing and assembly of the engine, not only t...
