The primary mirror bracing or strutting arrangement is to be used for that primary mirror is installed in primary mirror the basis is installed, and the primary mirror bracing or strutting arrangement also is vital.Though existing primary mirror bracing or strutting arrangement can satisfy the requirement of support accuracy; But can't isolate for the environment in the external world and the influence on installation basis; Malformation and hot-fluid that the basis is installed do not have and can be delivered on the primary mirror through the primary mirror bracing or strutting arrangement, and primary mirror is impacted.
The utility model content
Can't isolate extraneous environment and the influence of basis to primary mirror is installed in order to solve existing primary mirror bracing or strutting arrangement, the utility model provides a kind of primary mirror flexible supporting device.
The technical solution of the utility model:
A kind of primary mirror flexible supporting device, its special character is: comprises two back up pads that laterally arrange and is arranged on a plurality of support bars between two back up pads,
Said support bar comprises intermediate bar, be separately positioned on two connecting links between intermediate bar both ends and the corresponding back up pad, be separately positioned on the flexible transition part between connecting link and the intermediate bar;
Said flexible transition part comprises transition block, end web joint and middle connecting plate; Said end web joint and intermediate bar parallel axes, one of which end and connecting link are connected, and its other end and transition block are connected; Said middle connecting plate and intermediate bar parallel axes, one of which end and intermediate bar are connected, and its other end and transition block are connected; Said end web joint is vertical each other with middle connecting plate; The other end of said two connecting links all is connected with corresponding back up pad;
Be provided with two L shaped through slots between said transition block, end web joint and the connecting link, said two L shaped through slots along the end web joint symmetrical;
Be provided with two L shaped through slots between said transition block, middle connecting plate and the intermediate bar, said two L shaped through slots are symmetrical along middle connecting plate;
Be filled with L shaped elastic damping pad in said four L shaped through slots.
The corner of above-mentioned L shaped through slot is rounded down.
The advantage that the utility model had:
1, be provided with the flexible transition part on the utility model support bar, the flexible transition part comprises transition block, end web joint and middle connecting plate; End web joint and intermediate bar parallel axes, one of which end and connecting link are connected, and its other end and transition block are connected; Middle connecting plate and intermediate bar parallel axes, one of which end and intermediate bar are connected, and its other end and transition block are connected; The end web joint is vertical each other with middle connecting plate; The other end of two connecting links all is connected with corresponding back up pad; Be provided with two L shaped through slots between transition block, end web joint and the connecting link, said two L shaped through slots along the end web joint symmetrical; Be provided with two L shaped through slots between transition block, middle connecting plate and the intermediate bar, two L shaped through slots are symmetrical along middle connecting plate; The flexible transition part can effectively be isolated the influence to primary mirror of malformation that the basis is installed and hot-fluid.
2, the utility model is rounded down on the flexible transition part and can reduces stress and concentrate.
3, the utility model is through being fixed with the damping-constraining pad in each L shaped through slot; Can be in vibration processes consumed energy; Play damping effect; Reduce to be passed to the vibration on chassis, also can effectively improve the stress at flexible link place, prevent that flexible link from producing bigger stress and concentrating and cause flexible link destruction in vibration processes by the basis is installed.
4, fixing damping-constraining pad can prevent collision in the L shaped through slot.
