所谓点阵装卡是零件以一定的规则排列、定位并夹紧。点阵装卡夹具具有装卡密度高、结构紧凑、加工效率高和能适应特定工艺要求等优点。现举两例作一介绍。一、矩形点阵型夹具矩形点阵型夹具结构见图6。它用于在一个钉形零件上铣十字槽,每次装夹4×4=16件,用四把铣刀组合加工,在两个互相垂直的工位上,两次走刀完成。该夹具的关键零件是夹芯和紧箍。夹芯见图1,它对称地分成四个相同的组,每组包括O、A、B、C四个部
The so-called dot matrix card is the parts arranged in a certain order, positioning and clamping. Lattice card holder with a card installed high density, compact structure, high processing efficiency and can adapt to specific technological requirements and so on. Take two cases for an introduction. First, the rectangular lattice-type fixture Rectangular lattice-type fixture structure shown in Figure 6. It is used to make a cross slot on a nail-shaped parts, each clamping 4 × 4 = 16 pieces, with a combination of four milling cutter, in two mutually perpendicular station, two passes completed. The key parts of the fixture are the core and the clamp. The sandwich is shown in Figure 1, which is symmetrically divided into four identical groups, each group consisting of four sections O, A, B, C
