The invention discloses a production process of an automobile compressor support bushing. The production process comprises the steps of carrying out pressure casting: particularly carrying out die assembly, filling die casting, die opening, sliding block opening, workpiece taking by a mechanical arm, spraying and air blowing and repeating of the steps; carrying out post-machining: particularly removing slag ladle nozzle residues and carrying out surface shot blasting treatment; and carrying out machining: particularly carrying out machining roughing by a phi31 milling cutter, carrying out finemachining by a phi31 reamer, carrying out reverse face and chamfering machining by a phi31 reverse milling cutter. By improving a machining assembly hole, the flange edge overflow phenomenon occuringduring bushing press fitting is reduced, and the pull-out force of the bushing is improved , so that the vibration test capability is improved, and the safety of a whole vehicle is further improved.

    本发明公开了一种汽车压缩机支架衬套的生产工艺,压铸:合模→充填压铸→开模→滑块打开→机械手取件→喷雾吹气→重复以上步骤;后加工:去除渣包水口残留并作表面抛丸处理;机加工:φ31铣刀加工开粗→φ31铰刀精加工→φ31反面面及倒角反铣刀加工。本发明通过改善机加工装配孔,减少衬套压装时法兰边溢出现象,来改善衬套的拔脱力,从而提高振动试验能力,进而增加整车安全性。
