刚性不足、形状不规则的零件,如何定位与可靠的夹紧,往往成为机械加工中的难题。有时不得不把所要求的技术条件降低,有时只好把零件壁加厚,以增强其刚性。甚至被迫更改设计,将整体结构改变成为组合式的结构。为此,工艺人员针对不同类型零件,在工艺路线、工艺装备方面想了很多办法。后又在工艺加固方法上进行了研究。一、工艺加固原理及工艺加固剂工艺加固的新方法是用自凝固物质,在液体状态时,填充被加工零件空腔或包裹零件。当其凝固后,和零件形成一刚性体,以便在零件机械加工过程中, Rigid, irregular shape of the parts, how to position and reliable clamping, often become a mechanical problem. Sometimes having to degrade the required technical conditions, sometimes thickening the part walls to enhance their rigidity. Even forced to change the design, the overall structure changed into a modular structure. To this end, the craft staff for different types of parts, in the process route, technology and equipment, a lot of ways. After that, the method of reinforcement was studied. First, the principle of strengthening the process and technology Reinforcement process reinforcement method is the use of self-solidifying material, in the liquid state, filling the processed parts cavity or package parts. When it solidifies, and the parts form a rigid body, so that in the parts machining process,
