Abstract
A variable damping vibration isolation footstand optical platform comprises a platform surface and a variable damping vibration isolation footstand. The variable damping vibration isolation footstand comprises an outer shell, a base plate, a spindle, a damping air chamber and a damping adjusting valve. The outer shell is installed on the base plate. A hole is formed in the center of the top of the outer shell. The spindle penetrates into the hole. The damping air chamber is arranged inside the outer shell. The damping air chamber is divided into an upper layer and a lower layer. A throttling damping hole is formed between the upper layer and the lower layer of the damping air chamber. An air pipe is arranged outside the outer shell. One end of the air pipe is connected to the upper layer of the damping air chamber, the other end of the air pipe is connected into the lower layer of the damping air chamber, and the damping adjusting valve is arranged on the air pipe. According to the variable damping vibration isolation footstand optical platform, the damping effect can be adjusted externally, the vibration isolation effect is good, and an optical test is more accurate.
Description
Technical field
The utility model relates to a kind of optical test instrument, specifically a kind of damping isolation runners optical table that becomes.
Background technique
In optical test, optical table is extremely accurate important tests equipment, it need to have resistance to shock and dimensionally stable performance highly, it is to be combined into by optical table and support device, optical table is placed on the support device with vibration isolation phychology, impact test being produced to reduce extraneous vibration, height level simultaneously that also keep optical table upper surface, optical test element is fixed by screws in optical table upper surface and forms light path system.
Existing vibration isolation support, in the situation that resisting medium is certain, damping function effect is constant, but the frequency of vibration source is often to change, thereby do not reach good vibration isolating effect.If change damping function effect, must change damping and connect child's characteristic temperature viscosity, namely necessary replacing resisting medium, therefore existing vibration isolation support can not meet vibration environment and changes occasion frequently.
Model utility content
The deficiency existing for above-mentioned prior art, the purpose of this utility model is to provide that a kind of damping is variable, change damping isolation runners optical table that can meticulous continuous adjusting.
The technical solution of the utility model is: a kind of damping isolation runners optical table that becomes, comprise table top, become damping isolation runners, it is characterized in that: described change damping isolation runners comprises shell, base plate, main shaft, damping air chamber, damping modulating valve, described shell is contained on base plate, cover top portion center is provided with a hole, main shaft penetrates in this hole, in shell, be provided with damping air chamber, damping air chamber is divided into, lower two-layer, between upper strata damping air chamber and lower floor's damping air chamber, be provided with throttle hole, there is a tracheae at shell peripheral hardware, tracheae one end is connected in upper strata damping air chamber, the tracheae the other end is connected in lower floor's damping air chamber, tracheae is provided with damping modulating valve.
As a preferred version, on base plate, be provided with antiskid glue cushion, when use, do not need vibration isolation runners to be fixed on ground, have can arbitrarily shift one's position, flexibly, feature easily.
The utility model has the advantages that: the response that double layer damping air chamber described in the utility model vibration isolation excites due to ambient vibration in the time of work can produce low-frequency alternating distortion, the moving direction that makes gas all can change self in the each forced cycle of being flowing in of throttle hole reduces natural frequency to produce damping force.2 air chambers is connected by outside tracheae, and on tracheae, (particular location is on termination) is furnished with variable damper valve, can regulate the effect of damping by outside, and vibration isolating effect is good, makes optical test more accurate.
Brief description of the drawings
Fig. 1 is the utility model structural representation.
Fig. 2 is the structural representation of change damping isolation runners described in the utility model.
Embodiment
Now by reference to the accompanying drawings, the utility model is further described.
As Fig. 1, shown in Fig. 2, a kind of damping isolation runners optical table that becomes, comprise table top 1, become damping isolation runners 2, it is characterized in that: described change damping isolation runners 2 comprises shell 2.1, base plate 2.2, main shaft 2.3, damping air chamber 2.4, damping modulating valve 2.6, described shell 2.1 is contained on base plate 2.2, shell 2.1 top center are provided with a hole, main shaft 2.3 penetrates in this hole, in shell 2.1, be provided with damping air chamber 2.4, damping air chamber is divided into, lower two-layer, between upper strata damping air chamber and lower floor's damping air chamber, be provided with throttle hole 2.5, outside shell 2.1, be provided with a tracheae 3, tracheae 3 one end are connected in upper strata damping air chamber, tracheae 3 the other ends are connected to lower floor's damping air chamber, tracheae 3 is provided with damping modulating valve 2.6.On base plate 2.2, be provided with antiskid glue cushion 4, when use, do not need vibration isolation runners to be fixed on ground, have can arbitrarily shift one's position, flexibly, feature easily.
Damping air chamber 2.4 described in the utility model adopts MULTILAYER COMPOSITE rubber material, and internal layer adopts butyl rubber to improve the tightness of product; Skin adopts anti-aging natural rubber, improves the intensity of product, has increased endurance life and the aging-resistant performance of product, has improved working life.The response that the pneumatic vibration isolation of two air chambers excites due to ambient vibration in the time of work can produce low-frequency alternating distortion, and the moving direction that makes gas all can change self in the each forced cycle of being flowing in of throttle hole 2.5 reduces natural frequency to produce damping force.2 air chambers is connected by outside tracheae, and termination is furnished with variable damper valve, can regulate the effect of damping by outside.
