Processing efficiency is lower.
For small-bore optical crystal element, traditional Cold-forming process is mostly that disk polishing, but hand are thrown or be bonded to hand
The precision stability of throwing is poor, relatively relies on the skill of operator, and bonds the local thermal stress that upper disk generates and easily cause crystalline substance
The cracking of body material especially to the thermally sensitive material such as clbo crystal, or brings heterogeneous deformation to lead to element lower wall
Precision deteriorates afterwards.
Utility model content
The technical problem to be solved by the utility model is to provide a kind of clampings of the good small-bore optical element of stability
Device.
The utility model technical scheme applied to solve the technical problem is: the clamping device of small-bore optical element, packet
Include substrate, ceramic ring, shape connecting plate, block, adjust screw, accompany and throw piece and separator, it is described to accompany the quantity and element for throwing piece
Side quantity match；The quantity of the block accompanies the throwing quantity of piece consistent with described；It is described that throwing piece is accompanied to lie on substrate；
The block side is provided with adjusting screw, for the fixed relative position for accompanying throwing piece and element；The ceramic ring and separator
By shape connecting plate link together；The center opening of the separator, to place the block.
Further, the lower surface of the block and the substrates while stacking.
Further, it the block and accompanies and throws piece and all use four, and four blocks surround rectangular shape.
Further, the ceramic ring and separator are fixed by screw.
Further, the element is lain on substrate, and keeps machined surface and substrates while stacking.
Further, the flatness of the substrate is better than 1 μm.
Further, the size for accompanying throwing piece is 20mm × 20mm × 20mm.
Further, the material for adjusting screw is polytetrafluoro, and the material for accompanying throwing piece is nylon.
Further, the lower surface of the separator and the lower surface of ceramic ring are at a distance of 1-2mm.
The beneficial effects of the utility model are: small-bore element may be implemented by accompanying throwing piece to combine elements into intimate
Quick-clamping can adapt to the element of different shapes and size, and versatility is good, and clamping is simple, and stability is good, improve small-bore
The problem of element machining accuracy control hardly possible, low efficiency；Quick-clamping can be carried out to different size element (Φ < 20mm), it is especially suitable
For the special process requirements of small-bore optical element, the processing quality and processing effect of small-bore optical crystal element can be improved
Rate；The utility model can avoid in hot sticky connection disk and crack wind to element bring for the special materials clamping such as clbo crystal
Danger.
