| Abrasive flow polishing machine tool fixture is mainly special fixture, the problem is that the strong specificity, poor universality, low utilization. To solve the problems of abrasive flow polishing machine tool fixture, puts forward the application of modular fixture to abrasive flow polishing machine tool.After the research of the abrasive flow polishing machine tool modular fixture’s characteristics and requirements, designed the abrasive flow polishing machine tool modular fixture with specificity and universality. The modular fixture using slot and hole structure of combining, in smaller axial force using slot structure; in stress big radial using spline hole structure, not only ensure jig stiffness and strength, but also improve the generality. With the fixture, various parts of the large different shape and size large difference can be achieved machining on the abrasive flow polishing machine abrasive, for parts with similar characteristics, the fixture elements general degree is high, interchangeability is good.The simulation analysis is that the bend and gear get good processing effect through using the modular fixture on the abrasive flow polishing machine tool. If combine the fixture elements, the machining efficiency can be improved integer times. A bend in the abrasive flow polishing machine tool using modular fixture on its surface finishing processing,processing can improve 6 times, the most efficient one tooth surface of gear machining efficiency highest can improve eight times. Use of abrasive flow polishing machine tool modular fixture to finish the processing of the bending tube inner surface, processing can improve 6 times, for the gear tooth surface processing, machining efficiency can improve eight times. |
