Abstract
This patent discloses a kind of four-degree-of-freedom parallel connection isolation mountings, belong to vibration isolator field, and its object is to the precision instruments being guaranteed on vehicle-mounted, airborne, carrier-borne to have stable working environment.For this patent using four-freedom parallel mechanism as main body configuration, structure mainly includes upper mounting plate, left spring, damper, right spring, branch, lower platform several major composition.External interference is inputted by lower platform, by passing to upper mounting plate after then damping action, in three main freedom degree directions, i.e., along three reference axis moving directions, can achieve 80% vibration isolating effect.Single unit system has the characteristics that occupancy is small in size, mechanism structure is simple, own wt is light, bearing capacity is strong.
Description
Technical field
The present invention relates to a kind of four-degree-of-freedom parallel connection isolation mountings.
Background technique
Precision instrument inevitably will receive road surface during transport or transition or adapt to environment bring difference
The interference and vibration in direction, these vibrations affect their service precision and service life to some extent.The present invention can be on edge
X, Y, Z and turn about the Z axis direction isolation vibration interference, guarantee that precision instrument has a stable working environment.
Summary of the invention
The purpose of the present invention is to provide a kind of devices for precision instrument vibration isolation.Four-degree-of-freedom parallel connection isolation mounting by
Main body mechanism, spring, the damping connectors such as several major and bolt, nut composition, each section installation connection are as follows: main body mechanism
For four-freedom parallel mechanism, upper and lower platform passes through spring damping branch chain link；Every branch is damped by two springs and one
Device connects in the way of in parallel.
External interference is inputted by lower platform, and upper mounting plate carries precision instrument.In three main freedom degree directions, i.e., along three
Reference axis moving direction can achieve 80% vibration isolating effect.
Compared with prior art, the present invention at least has the advantages that: the present invention occupies small in size, mechanism structure
Simply, own wt is light, bearing capacity is strong, it can be achieved that along X, Y, Z and turning about the Z axis the vibration isolation in direction, makes accurate instrument
The significant reduction in vibration that device is subject to.
Below by drawings and examples, technical scheme of the present invention will be described in further detail.

In figure: upper mounting plate 1；Left spring 2；Damper 3；Right spring 4；Branch 5；Lower platform 6；
Specific embodiment
In conjunction with attached drawing, the present invention will be further described.
Four-degree-of-freedom multidimensional vibration-isolating apparatus is by upper mounting plate 1, left spring 2, damper 3, right spring 4, branch 5, lower platform more than 6
Most of composition.Lower platform 6 is connect by U pair with four branches 5.Branch 5 includes: left spring 2, damper 3,4 groups of right spring
At.Upper mounting plate 1 is connect also by U pair with four branches 5.Upper mounting plate 1 is used to carry precision instrument.
External interference inputs isolation mounting by lower platform 6, passes to upper mounting plate after the effect by the spring damping of branch 5
1.In this process, the parameter of spring damping through reasonable settings has the vibration of 20-200Hz 80% vibration isolation
Effect.
Although a specific embodiment of the invention is disclosed above, it is not intended to limit the invention the range of implementation.It is any
Those skilled in the art are not departing from invention scope of the invention, improve when can make a little, i.e., all according to this
The same improvement done is invented, the scope of the present invention is should be and is covered.
