Embodiment Construction

[0029] The technical solutions of the present invention will be described in detail below through specific examples.

[0030] In this embodiment, the large-amplitude vibration active isolation bar includes three parts: a mover 1 , a stator 2 and a position sensor 3 . The mover 1 is composed of an inner support cylinder 4, a linear guide rail slider 7, a linear guide rail 8, and a motor mover 9; the stator 2 is composed of a dust cover 5, a guide rail fixing plate 6, a motor stator 10, an outer support cylinder 11, and a positioning screw 14 and the top positioning block 15; the position sensor 3 is composed of a grating fixing plate 13 and a grating sensor 12. The mover 1 is on the top and the stator 2 is on the bottom. The mover 1 moves up and down relative to the stator 2 to offset the vibration transmitted by the stator 2 and keep the mover 1 stable. The position sensor 3 is fixed on the stator 2 to detect the stroke of the mover 1 .

Abstract

A large-amplitude vibration active spacer bar consists of a rotor, a stator and a position sensor. When the large-amplitude vibration active spacer bar is in operation, the rotor is positioned at the upper part, the stator is positioned at the lower part and the rotor moves up and down relative to the stator so as to counteract the vibration transmitted from the stator and stabilize the rotor; the rotor consists of an internal support cylinder, a linear guide rail slide block, a linear guide rail and a motor rotor; the stator consists of a dustproof cover, a guide rail fixed plate, a motor stator, an external support cylinder, a positioning screw and a top positioning block; the position sensor consists of a grating fixed plate and a grating sensor. The large-amplitude vibration active spacer bar has the advantages of large stroke, large load capacity, quick response speed, high reliability, large vibration insulation amplitude, wide frequency band, etc.

Description

(1) Technical field: [0001] The invention relates to a large-amplitude vibration active isolation device, which belongs to the field of precision machinery. (two) background technology: [0002] The six-degree-of-freedom vibration isolation positioning platform is an active vibration isolation and precise positioning device applied to precision optical observation equipment and laser aiming equipment. It includes several parts such as upper platform, lower platform, active telescopic device, two-degree-of-freedom rotary hinge and three-degree-of-freedom rotary hinge. Through the telescopic movement of six active components, the upper platform can realize the movement of six degrees of freedom, and realize the functions of vibration isolation and precise positioning of six degrees of freedom. [0003] In the past, the active telescopic devices used in the six-degree-of-freedom vibration isolation positioning platform were mostly voice coil motors or piezoelectric ceramics, b...
