摘要: 產品組裝後的精度和品質的變異主要來自於組裝件之公差累積,然而高精度零件的公差要求嚴苛,導致生產成本提高,故亟需探討如何掌握組裝時造成的公差累積現象,以取得精度品質及生產成本間之平衡。本研究藉由分組選配的裝配方法,探討該方法之理論基礎以及該方法對於組裝後產品精度品質變異的影響。 在理論分析中,本文由組裝尺寸鏈的建構來分析組裝之公差累積,藉由分析方法中的極值法和統計法進一步推導分組選配之公差分析,極值法分別考量組裝之理想情況與最惡情況,確保產品的穩定性;而統計法以生產中常見的均勻分佈模式和常態分佈模式為代表,分析組合件之分佈狀況及變異範圍,結果顯示在不改變零件公差規格的條件下,組裝之公差累積與分組選配方式及其分組數相關,適當的分組選配可大幅降低組裝之公差;結果亦顯示組裝後之產品公差可以較零件之公差為低,亦即此方法可在不改變零件公差規格的條件下用以提昇產品之精度品質。研究進一步以組裝後之公差為限制條件探討分組選配以及零件公差之配置,結果顯示配置適當的分組數以及零件公差能達成設計之組裝公差,大幅降低產品公差設計與配置的複雜度。
The accuracy and quality variation of assembled parts are mainly from tolerance accumulation. Therefore high-precision components have strict demands on tolerance, resulting in production costs raising. So we need to discuss how to control the tolerance accumulation to obtain the balance between accuracy and cost. In this study, we use Selective fitting to discuss the variation in different group of assembled products. In theoretical analysis, we construct the dimensional chain of assembled parts to analyze tolerance accumulation. The extreme value method and statistical method for selective fitting analysis are utilized. The extreme value method can be used for ideal situation and the worst case simulation to ensure the stability of products. Then uniform distribution and normal distribution can be used to predict the variation and distribution of assembled parts. The results show if not change tolerance, the tolerance accumulation and selection are related to groups. Appropriate selections can remarkable decrease the tolerance of assembled parts. And the tolerance of assembled parts is also lower than components. This method can be used for increasing accuracy and quality without changing component tolerance. Moreover, selective fitting and tolerance allocation of components with tolerance restriction after assembled shows appropriate group and component tolerance can accomplish tolerance of assembled parts and decrease complexity of tolerance design and allocation.
