Abstract
The utility model discloses a rigid body hinging structure using a leaf spring hinge and the leaf spring hinge thereof. The structure comprises a first rigid body and a second rigid body hinged to the first rigid body through the leaf spring hinge, the leaf spring hinge comprises two integrally arranged L-shaped leaf spring arms, the first rigid body comprises two mutually vertical side surfaces, the two side surfaces are in transitional connection through a first gap, the two side surfaces of the first rigid body are respectively fixedly connected with the tail ends of the two leaf spring arms, and the leaf spring hinge is fixedly connected with the second rigid body through the joint part of the two leaf spring arms. In the leaf spring hinge with the structure and the rigid body hinging structure using the leaf spring hinge, the leaf spring hinge is in an L-shaped structure, has a simple structure and process and high movement precision and occupies small space.
Description
Technical field
The utility model relates to a kind of rigid body hinging structure and sheet spring hinge thereof that uses sheet spring hinge, belongs to the precision machinery technology field.
Background technique
Sheet spring elastic hinge is a kind of micrometric displacement hinge that can support and can lead, have higher displacement resolution and and guiding accuracy since its volume little, do not have machinery friction, no gap, movement sensitive advantages of higher and be widely used in the inductive displacement transducer.The angle that sheet spring elastic hinge can provide, linear displacement motion can be realized by its resiliently deformable, its precision is to realize that by sheet spring hinge the accuracy of motor function decides, under the effect of power, perfect condition is that rigid body is only around a fixing gyration center rotation, but the working position of the resiliently deformable of sheet spring, structural parameter and external force and direction all can have influence on the exercise performance of sheet spring elastic hinge in actual applications, thereby make the gyration center generation skew of rigid body influence its kinematic accuracy.
Application number is that 98200951.8 patent has been announced two kinds of rigid structures of a kind of V font sheet spring formula hinge and application thereof, two sheet springs of this V font sheet spring formula hinge couple together two rigid bodies, one end of two sheet springs is overlapping on rigid body therein, the other end is separately fixed at and forms the V font on the another one rigid body, and the intersection of two sheet springs is exactly a rigid body axis in relative rotation.This V font sheet spring formula hinge has limited extra dof reliably, and it is little to take up room, but the two ends of two sheet springs all need to fix assembling, processing technology complexity by fastening piece and rigid body after the bending.
The model utility content
The purpose of this utility model has provided a kind of rigid body hinging structure that uses sheet spring hinge, in order to solve sheet spring hinge processing technology complicated problems, provides the sheet spring hinge of this structure simultaneously.
For addressing the above problem, the rigid body hinging structure of the utility model sheet spring hinge adopts following technological scheme: a kind of rigid body hinging structure that uses sheet spring hinge, comprise first rigid body and be articulated in second rigid body on first rigid body by sheet spring hinge, described spring hinge comprises two sheet spring arms that L type structure is wholely set, described first rigid body comprises mutually perpendicular two sides, two sides connect by the first breach transition, fixedly connected with the terminal of described two sheet spring arms respectively in two sides of described first rigid body, described spring hinge fixedlyed connected with second rigid body by two interconnective parts of spring arm.
Offer corresponding with described first breach on described second rigid body and be used to place second breach of sheet spring hinge, described second rigid body is by fixedlying connected with sheet spring hinge with described second breach sheet spring briquetting that cooperates that coincide.
The end of described two sheet spring arms is respectively equipped with sheet spring pressing plate, and described spring pressing plate fixedlyed connected with described spring arm by resilient key respectively.
For addressing the above problem, the utility model sheet spring hinge adopts following technological scheme: a kind of spring hinge, described spring hinge comprises two sheet spring arms that are wholely set of L type structure.
The end of described two sheet spring arms is respectively equipped with sheet spring pressing plate, and described spring pressing plate fixedlyed connected with described spring arm by resilient key respectively.
Adopt the rigid body hinging structure of the use sheet spring hinge of said structure, the sheet spring hinge of this structure is two sheet spring arms that L type structure is wholely set, and structure, technology are simple, and the kinematic accuracy height, and it is less to take up room.

Embodiment
Shown in Fig. 1-4, the utility model uses the embodiment of the rigid body hinging structure of sheet spring hinge: comprise rigid body 7 and be articulated in rigid body 5 on the rigid body 7 by sheet spring hinge 2, described spring hinge comprises two sheet spring arms that L type structure is wholely set, the end of two sheet spring arms is respectively equipped with sheet spring pressing plate 1 and sheet spring pressing plate 3, and sheet spring pressing plate 1 is fixedlyed connected with sheet spring hinge 2 by resilient key 4 respectively with sheet spring pressing plate 3.Rigid body 7 comprises mutually perpendicular side 71 and side 72, and side 71 is connected by breach 8 transition with side 72, and the sheet spring pressing plate 1 of sheet spring hinge 2 ends is fixed with the side of rigid body 71, sheet spring pressing plate 3 is fixing with side 72.Offer corresponding with breach 8 on the described rigid body 5 and be used to place the breach 9 of sheet spring hinge 2, rigid body 5 is by fixing with sheet spring hinge 2 with the breach 9 sheet spring briquettings 6 that cooperate that coincide.
Sheet spring hinge in the rigid body hinging structure of the embodiment of the utility model sheet spring hinge and above-mentioned use sheet spring hinge is consistent, so no longer describe at this.
During use, sheet spring hinge 2 is fixed on the indentation, there of rigid body 5 by sheet spring briquetting 6, the sheet spring pressing plate 1 on the sheet spring hinge 2 and the side of rigid body 7 are 71 fixing, sheet spring pressing plate 3 is fixing with side 72.Do the time spent when rigid body 5 is subjected to external force F, rigid body 5 is the gyration center rotation with the intersection of the both ends of the surface of sheet spring hinge 2.
