Upplýsingar um vöru
- 治具の狙いをひと言でいえば、「楽に作業するため」です。楽に作業できれば「品質が上がって」「早く作業ができて」「安くつくれる」のです。 治具を設計する上で必要な知識は「メカ設計の知識」と「作業設計の知識」の二本柱。機械の設計には、前者のメカ設計の知識だけで良いのですが、治具を使う主体は人なので、楽にできる作業性がとても大切です。これが「作業設計」になります。 本書では、治具をはじめて設計する方や、基礎をきちんと学んでみたいと思っている方を対象に、メカ設計と作業設計を解説します。 【目次】 治具を導入する狙い 〇1.1 治具とは 〇1.2 治具の効果と基本要素 位置決め方法 〇2.1 位置決めの基本 〇2.2 角形状の端面基準「面当たり方式」の位置決め 〇2.3 角形状の端面基準「ピン当たり方式」の位置決め 〇2.4 角形状の端面基準「調整方式」の位置決め 〇2.5 角形状の穴基準「丸ピン方式とダイヤピン方式」の位置決め 〇2.6 角形状の穴基準「長穴方式とダボ方式」の位置決め 〇2.7 角形状の底面基準の位置決め 〇2.8 丸形状の位置決め 固定方法 〇3.1 固定の基本 〇3.2 市販の固定具 〇3.3 丸形状の固定方法 〇3.4 固定の機構 〇3.5 真空吸引による固定 ねじの活用 〇4.1 ねじの基礎知識 〇4.2 メートルねじ 〇4.3 ねじとボルトの種類 〇4.4 ねじの選び方 〇4.5 ねじ関連の知識 運動の案内と測定器 〇5.1 平面運動の案内部品 〇5.2 往復直線運動の案内部品 〇5.3 回転運動の案内部品 〇5.4 治具に便利な機械要素部品 〇5.5 測定の基礎 〇5.6 直接測定の測定器 〇5.7 間接測定の測定器 〇5.8 その他の測定器 作業性と段取り性 〇6.1 効率の良い作業手順と作業環境 〇6.2 作業性の良い治具構造とミスを防ぐポカヨケ 〇6.3 段取り改善 設計のコツ 〇7.1 頑丈な設計のコツ 〇7.2 材料の重さと熱による影響 〇7.3 はめあい公差のコツ 〇7.4 標準化を進めるコツ
