Description
本願は、2019年6月7日に出願された米国仮出願第62/858,723号、及び、2019年6月7日に出願された仮出願第62/858,733号の、米国特許法第119条に基づく優先権の利益を主張し、各々の全内容が参照により本願に組み込まれる。
開示される主題は、大型複合構造体、例えば風力タービンブレードを製造するシステム、及び対応する方法に関する。これら大型複合構造体は、典型的には二つの部分から成る金型から形成されるが、その場合、製作を完了するためには、ブレードの半体の成形後に、複雑な部品位置特定/据付け、及び後続の金型閉鎖の工程が必要になる。
本明細書に記載する方法及びシステムは、成形工程中の部品、例えばスパーキャップの、高精度の設置を容易にする。特に、本開示は、ブレード翼幅全体にわたって正確な幾何的基準点を提供し、いくつかの実施形態では、剛性の支持表面を必要とする部品に対する機械的停止部として使用できる正確な幾何的基準点を提供する、新規な装置及び方法を導入する。いくつかの実施形態では、本開示は、位置特定を支援するためのオーバーヘッド光学投影システム及びレーザトラッキングシステムと、レイアップ工程中に部品及び補強層を設置するための測定ツールと、を含み得る。
図4(A)~図4(F)には、本明細書で開示される実施形態内で採用され得る、追加の又は代替のピン構成が描かれている。図4(A)に示す例示的なピン実施形態では、ピンは、ピン穴(100)内に挿入される第2のセクション(402)よりも大きい断面積を有する、第1のセクション(401)を含み得る。面積の変化は、図4(A)に示すような急激な若しくは階段状の変化、又は図4(B)に示すような漸進的なテーパであり得る。加えて又は代替として、ピン(400)の遠位端は、図4(A)に示すようにピン穴(100)の底部から離間させること、又は、図4(B)に示すようにピン穴の底部に当接するように延在することができる。
図6(b)には、ピン穴内への樹脂の進入を回避するためにブレード製造ステップ(例えばゲル適用)の前にピン穴(1000)の中に少なくとも部分的に挿入することのできる、スタッド部材(2000)が描かれている。いくつかの実施形態では、スタッド(2000)はブレード金型表面よりも上まで延在するようなサイズとなっており、穴(1000)の中に(例えば、摩擦嵌めを介して、又はねじ式固定具、さねはぎ継ぎ等を介してのいずれかで)永続的に又は着脱可能に固定され得る。
上で言及したように、本明細書で開示される実施形態内で、様々なピン構成が採用され得る。図6(b)に示す例示的なピン実施形態では、ピンは、ピン穴(1000)内のスタッド(2000)に挿入され、これを受け入れ、又はこれに取り付けられる第2のセクション(4002)よりも小さい断面積を有する、第1のセクション(4001)を含み得る。面積の変化は、急激な若しくは階段状の変化、又は漸進的なテーパであり得る。加えて又は代替として、スタッド(2000)の遠位端は、ピン穴(1000)の底部から離間すること、又はピン穴の底部に当接するように延在することができる。
