Abstract
Disclosed is a stable optical precision machinery carriage used for connection and support in an optical precision machinery structure. The utility model comprises two or more than two hollow metal tubes; loose granular fillers are filled in the hollow space of the metal tube; two support boards are arranged at both ends of the metal tube for fixation. The granule fillers in the hollow metal tube collide with each other for realizing the function of damping when the carriage is vibrated; the vibration energy is consumed by the damping to make the instant vibration quickly die off, avoiding the production of free vibration, particularly reducing the vibration of a forced vibration resonance region and effectively controlling the production of vibration. Compared with the prior art, the carriage formed by no filler hollow metal tubes or bars, the utility model reaches the purpose of vibration reduction and improves the stability of an optical system composed of support optical elements.
Description
Technical field:
The utility model is a kind of stable optical precision optical machinery bracing frame.Mainly in the optical precision optical machinery structure, use as syndeton and supporting construction.
Background technology:
Formerly in the technology, common metal pipe or metal bar are as connecting and support component in many optical precision optical machinery structures, especially for being used for connecting and supporting various optical elements, formerly hollow metal tube in the technology or metal bar, under the effect of various external force at random, will produce forced vibration at random, thereby influence the stability of the whole optical system that constitutes by optical element.
Summary of the invention:
The purpose of this utility model is for the structure that overcomes optical precision optical machinery bracing frame in the technology formerly deficiency aspect stable, provide a kind of damping characteristic of bracing frame self of utilizing to reduce the interference of some forced vibrations at random, thereby improve the stability of the optical system of whole used bracing frame.
The stable optical precision optical machinery bracing frame of the utility model mainly contains N 〉=2 a hollow metal tube 201,202,203,204, is filled with the filling material 301,302,303,304 of loose granule shape in metal tube 201,202,203,204 hollow.There are first back up pad 1 and second back up pad 4 to be fixed respectively at the two ends of metal tube 201,202,203,204.As shown in Figure 1 and Figure 2.
The filling material 301,302,303,304 of said loose granule shape is a foam grain, or small sponge ball, or small irregular fibrous nodules.
Be filled with the filling material 301,302,303,304 of loose granule shape in the said metal tube 201,202,203,204, in the process of vibration, to produce collision between these loose granule and consumed energy, play the effect of damping, damping consumes the energy of vibration, and transient oscillation is decayed rapidly, avoid the generation of autovibration, can reduce the vibration of forced vibration resonance region especially, therefore can control generation of vibration well, improve the stability of total system.Compare with the hollow metal tube or the metal bar of non-filler used in the technology formerly, the utility model promptly is to consume the energy of the random vibration of whole bracing frame by the mutual collision between the particle of the filling material of the loose granule shape that is filled with in the hollow metal tube 201,202,203,204, transient oscillation is decayed rapidly, thereby reach the purpose of damping, the stability of the whole optical system that is made of supporting optical component is improved.
Description of drawings:
Fig. 1 is the stable structural representation of optical precision optical machinery bracing frame when N=2 of the utility model.Fig. 1-the 1st wherein, the positive cross-sectional schematic of bracing frame, Fig. 1-2 is an A-A face cross-sectional schematic among Fig. 1-1
Fig. 2 is the stable structural representation of optical precision optical machinery bracing frame when N=4 of the utility model.Fig. 2-the 1st wherein, the positive cross-sectional schematic of bracing frame, Fig. 2-the 2nd, A-A face cross-sectional schematic among Fig. 2-1
Embodiment:
During example 1:N=2, as shown in Figure 1.
During example 2:N=4, as shown in Figure 2.
Shown in Fig. 1 (or Fig. 2) is the cover light path Adjustment System that the stable optical precision optical machinery bracing frame of the utility model is used for device of high power laser, mechanical support frame has wherein just used the stable optical precision optical machinery bracing frame of the utility model, being filled with granular filling material 301,302 (or 301,302,303,304) in two (or four) stainless-steel tubes 201,202 (or 201,202,203,204) wherein is foam grain, with first back up pad 1 and optical precision optical machinery bracing frame of second back up pad, 4 common formations.Wherein the center of first back up pad 1 and second back up pad 4 is fixed with the optical adjusting frame that studs with optical mirror slip respectively, and laser beam passes through from the center of two optical mirror slips.In order to guarantee the long-time stability of optical system, guarantee that just laser beam can pass through from the center of two optical mirror slips accurately, requires the precision optical machinery supporting construction that advantages of higher stability will be arranged, and can eliminate the interference of forced vibration at random.Stable optical precision optical machinery bracing frame used in the present embodiment just can consume the energy of the random vibration of whole mechanical system by the mutual collision between foam grain loose in two (or four) stainless-steel tubes 201,202 (or 201,202,203,204), transient oscillation is decayed rapidly, thereby reach the purpose of damping, improved the stability of whole physical construction and optical system.
