摘　　要：某制动器底板上镗孔加工,原来采用螺栓夹紧方式,零件受力不均,导致变形,合格率极低,而且一次只能加工一件零件。本文设计了压板式液压保压结构的夹具,通过旋转轴转动角度来实现压板对零件的夹紧和松开,一次可同时装夹3个零件,保证了大批量零件生产进度和加工质量,同时减轻了劳动强度,提高了工作效率。Bolt clamping is used to bore hole on a brake base, this means bring about uneven loading and de- formation, the qualified rate of the workpieee is extremely low, and only one part can be processed at a time. This paper designed a clamping plate fixture with hydraulic pressure holding structure, through the rotation an- gle of rotating shaft to achieve the clamping and loosening the workpiece, besides, clamping and machining 3 parts at one time. This way ensured the production progress and quality of batch production, meanwhile, re- duced labor intensity and improve work efficiency.
