This is a basic requirement of the optical fiber connector. To a certain extent, the quality of the optical fiber connector affects the reliability and various performances of an optical transmission system.
In order to meet the quality requirements of the optical fiber connector and avoid affecting the optical transmission system, after the optical fiber connector is formed, it is necessary to use grinding equipment to grind the ferrule; in order to facilitate grinding and avoid the product failing due to the offset of ferrule during grinding, it is necessary to use a grinding clamp to fix and clamp the ferrule.
The grinding clamp in the prior art comprises a clamp main body and multiple clamping blocks. The clamping blocks are mounted on the clamp main body via a bolt, and a clamping gap for clamping a product is formed between the clamping block and the clamp main body. It is necessary to manually adjust the bolts one by one by an operator so as to adjust the size of the clamping gap, thereby achieving the disassembly and assembly of the product; the operation process is tedious and the disassembly and assembly efficiencies are low; in addition, due to a large number of clamping blocks on the clamp main body and a large number of connecting pieces, assembly errors are likely to occur, which affects the stability of product clamping.
