【摘要】：贮油缸组件是轿车减振器的三大组件之一,传统结构是在贮油缸底部过盈压装一个底盖并焊接密封,以便密封内部的油液和气体。传统工艺在完成该工序的产品往往因过盈压装而产生难以清除的铁屑,影响减振器的清洁度;同时因压装难以保证底盖端面与贮油缸的垂直度,致使减振器使用过程中发生活塞杆偏磨,过早漏油失效而降低其使用寿命。针对以上存在的问题,通过对产品工装模具优化设计,具体包括:优化底盖和贮油缸配合关系,将原过盈配合关系变为间隙配合;优化设计底盖缩固工装等,从而杜绝在装配过程中铁屑的产生和提高底盖与贮油缸垂直度,最终达到降低减振器异响故障率,延长产品使用寿命的目的。具体的应用及产品质量检验的结果表明本模具优化设计方案是合理、可行的。
[Abstract]:The oil tank assembly is one of the three components of a car shock absorber. The traditional structure is to fill a bottom cover and weld seals at the bottom of the oil tank to seal the internal oil and gas. It is difficult to guarantee the perpendicularity of the end cover end and the oil storage cylinder, resulting in the slant wear of the life plug bar and the premature failure of the oil spill during the use of the damper. In view of the problems above, the optimum design of the tooling of the product is made, which includes the optimization of the relationship between the bottom cover and the oil tank, and the relationship of the original interference fit into the gap. In order to eliminate the production of iron chips and improve the perpendicularity of the bottom cover and oil tank in the process of assembly, the end cover and the verticality of the oil storage cylinder are eliminated in the process of assembly. The purpose of reducing the abnormal noise failure rate and prolonging the service life of the product is achieved. The concrete application and the result of product quality test show that the optimum design of the mold is reasonable and feasible.
