我厂各种试制产品批量很小 ,精度又较高 ,鉴于这种情况根据成组加工原理 ,对各种套类零件如滑杆套、定位套等进行分类 ,归纳出各种零件的共同特征与差异 (内孔、外圆、长短等 ) ,依据各参数设计钻模板和夹具体 ,如果参数相差不悬殊可以设计一个通用钻夹具 ,若加工孔径不同 ,可
I plant a variety of trial production of small quantities, high precision and, in view of this situation based on group processing principle, the various sets of parts such as slider sleeve, positioning sleeve, etc. are classified, summed up the common features of various parts And the difference (inner hole, outer circle, length, etc.), according to the parameters of the design of the template and the clip board, if the parameters are not different from each other to design a universal drill fixture, if the processing aperture is different,
