Abstract:
A grating bending device and a curved grating system therefor, the bending device comprising a support (100) and a clamping mechanism (200) used for clamping a grating (600). The clamping mechanism (200) is fixed on the support (100) by means of a bending adjustment mechanism (300); and the clamping mechanism (200) comprises clamping members (210) arranged in pairs and bonded to edges of the grating (600). Two clamping members (210) are arranged opposite to each other to clamp the grating (600), and the bending adjustment mechanism (300) drives the clamping members (210) to move toward the center to adjust the bending degree of the grating (600). The curved grating system comprises a curved grating (600) and a bending device. The present grating bending device may change a planar grating into a curved grating (600). The curved grating system may adjust the bending degree of the grating, has a simple structure, and is easy to fabricate.
