Compound rotary flexure hinge ring and rotating platform using same

Abstract

The invention relates to a compound rotary flexure hinge ring and a rotating platform using the same. The compound rotary flexure hinge ring comprises an aluminum alloy main ring and spring steel sheets; the aluminum alloy main ring comprises a first circular ring plate, a second circular ring plate and a plurality of connecting pieces, and the first circular ring plate and the second circular ring plate are connected by the multiple connecting pieces; the aluminum alloy main ring is machined and manufactured in an integral mode; and at least one connecting piece is internally provided with acutting slot opening, and the spring steel sheets are fixed in the cutting slot openings. According to the compound rotary flexure hinge ring, assembly errors can be effectively eliminated, strength can be improved, and the fatigue life can be prolonged.

Description

technical field [0001] The present invention relates to the technical field of a rotating platform, and more specifically, to a composite rotating flexible hinge ring and a rotating platform using the same. Background technique [0002] Flexible hinges are widely used in precision machinery, precision measurement, micro / nano technology and other fields due to their advantages of no friction, no gap and high sensitivity. At present, there are mainly two kinds of flexible hinges on the market: separate type or integral type. Among them, the separated type means that the relevant parts of the flexible hinge are processed separately and then assembled to form a flexible hinge. The flexible hinge can be made of high-strength materials, but there are assembly errors. The integral type is usually processed from one piece of material by wire cutting or milling. The aluminum alloy material that is easy to process is mainly used. The processing cost is low and there is no assembly er...

Problems solved by technology

Among them, the separated type means that the relevant parts of the flexible hinge are processed separately and then assembled to form a flexible hinge. High-strength materials can be used to manufacture flexible hinges, but there are assembly errors

The integral type is usually processed from one piece of material by wire cutting or milling. It mainly uses aluminum alloy materials that are easy to process. The processing cost is low and there is no assembly error, but it is difficult to guarantee its service strength, resulting in a short fatigue life.
