Embodiment Construction

[0023] This embodiment relates to a two-degree-of-freedom feeding device, including: figure 1 The primary amplification mechanism, such as figure 2 secondary amplification mechanism as shown in 3 or as image 3 The three-stage amplifying mechanism 3, the power unit 0 and the pretensioning device 5 are shown.

[0024] Such as Figure 1 ~ Figure 3 As shown, a force transmission component 6 is provided between the amplification mechanism 3 and the power unit 0, and the force transmission component 6 is a spherical or arcuate structure and is in point contact with the amplification mechanism 3 and the power unit 0, thereby realizing transmission There is no structural deformation stress during the force process.

[0025] The amplifying mechanism 3 includes a connecting rod group and a rotary shaft 4, wherein: the connecting rod group is composed of several rigid body straight rods which are sequentially connected head to tail, and the rigid body straight rods are arranged hori...

Abstract

The invention provides a two-degree-of-freedom feeding device and application of the two-degree-of-freedom feeding device. The two-degree-of-freedom feeding device comprises a power unit arranged in amachine body and an amplifying mechanism with one end in contact with the power unit, wherein the other end of the amplifying mechanism is used as a system output end to operate an object outside themachine body, the amplifying mechanism is connected with the power unit to receive driving output of the power unit, and when the machine body is driven to rotate, two-degree-of-freedom movement including rotation and translation is simultaneously realized through one rotation and / or external magnetic field. Through at least one stage of amplifying structure, the two-degree-of-freedom movement including translation and rotation can be realized through an integrated structure.

Description

technical field [0001] The invention relates to a technology in the field of mechanical processing, in particular to a two-degree-of-freedom feeding device and its application. Background technique [0002] Various existing intelligent actuators use piezoelectric ceramics, piezoelectric films, electrostrictive, magnetostrictive, shape memory alloys, servos and electrorheological fluids as power units. The emergence of these actuators provides the necessary conditions for the realization of high-precision active vibration control. However, the amplification and intelligent control of the power unit by existing devices cannot meet the industrial needs. Contents of the invention [0003] Aiming at the above-mentioned deficiencies in the prior art, the present invention proposes a two-degree-of-freedom feeding device and its application. Through at least one stage of amplification structure, the movement of two degrees of freedom in translation and rotation can be realized th...
