Multifunctional polishing and grinding clamp

The multifunctional polishing and grinding clamp comprises a clamp body, an angle block assembly and an upper disc base, the clamp body is fixed to the upper disc base, a fixing groove is formed in the clamp body, the angle block assembly is installed in the fixing groove, a metal pressing strip is further fixed to one inclined face of the clamp body, and the angle block assembly is installed in the metal pressing strip. The metal pressing strip corresponds to the fixing groove, a threaded hole is formed in the metal pressing strip, and an inclined included angle is formed between the central axis of the threaded hole and the horizontal plane of the fixing groove. According to the grinding and polishing device, the grinding and polishing requirements of different end face angles of chips and optical fiber arrays of different sizes are met by replacing different angle block assemblies. For new grinding and polishing samples, only proper angle block assemblies need to be designed and machined, manufacturing of
