Abstract: Aiming at the problems that every parts of each working procedure design special jig is still used to the similar characteristics of single piece and small batch gearbox parts and process efficiency is influenced, production cost is lifted, the similar gearbox parts similar characteristics analysis has been carried out, the similar gearbox parts in the same process to share a set of fixture and jig to satisfy the requirements has been put forward, a kind of from standardize the mold piece combines with appropriation mold piece of structure adjustable fixture design method was adopted. The method was based on standard parts library and template type module, and was drawn on modular fixture, the advantages of group fixture and special fixture. special parts design and manufacture of integrated into the thought of modular fixture was used, and it was made into the enterprise′s parameter, general,standard piece. And boring fixture subject before and after the practical use was compared. The results show that, compared with traditional special fixture design, this method obviously improves the similar gearbox fixture design and manufacture of speed, also reduces many similar fixture manufacturing, can effectively reduce the cost of production preparation.
