对可变加工系统夹具的要求是要具有好的适应性。通过改变工件结构和按夹压要求分成工件群可使夹具设计简化。实现夹具的可变性可采用托板化的组合夹具和自由布阵式非托板夹具两种方案。托板化夹具是在采用市售的槽式连接和孔配合式连接元件的基础上,补充设计基体件和某些夹压件和随带动力源而构成的。自由布阵式夹具的优点则为在一次工艺流程中,不需重装工件就可完成工件6个面正加工,但这种自由布阵夹具一些技术问题尚未解决,还仅处于初始发展阶段。图16幅。馆藏号:
The requirements of the variable processing system fixture is to have good adaptability. By changing the structure of the workpiece and pressed into the workpiece according to the requirements of the fixture can be simplified fixture design. To achieve the variability of the fixture can be used to combine the pallet and the free distribution of non-pallet fixture two options. Palletisation clamps are constructed on the basis of commercially available slotted and hole-fitted connecting elements, complementary design base pieces, and some crimping pieces and power sources. The advantage of the free arrangement of the fixture is in a process, without reloading the workpiece can be completed six workpieces are processing, but the freedom of array fixture some technical problems have not been solved, only in the initial stage of development.
