2.焊鉗選型與焊點(diǎn)可達(dá)性驗(yàn)證
在離線編程技術(shù)出現(xiàn)之前，焊鉗的選型和焊點(diǎn)可達(dá)性驗(yàn)證是通過對(duì)工件和夾具的數(shù)模進(jìn)行分析，依靠經(jīng)驗(yàn)完成的，焊鉗通常使用標(biāo)準(zhǔn)件。這樣的焊鉗選型和焊點(diǎn)可達(dá)性驗(yàn)證存在一定的風(fēng)險(xiǎn)，曾經(jīng)發(fā)生過到了客戶現(xiàn)場(chǎng)發(fā)現(xiàn)焊鉗與夾具、工件產(chǎn)生干涉的情況，焊鉗需要經(jīng)過反復(fù)修改才能達(dá)到要求，導(dǎo)致延誤了交工時(shí)間，并需追加更多成本。
使用離線編程技術(shù)可以有效避免類似情況的發(fā)生。利用仿真軟件，我們可以在訂購(gòu)焊鉗之前，對(duì)每一個(gè)焊點(diǎn)和程序過渡點(diǎn)進(jìn)行可達(dá)性和干涉性驗(yàn)證，當(dāng)出現(xiàn)干涉情況時(shí)，可以非常直觀并有針對(duì)性地對(duì)焊鉗鉗口形狀、喉深和喉寬等參數(shù)提出修改意見，直至確定出適合工件上所有焊點(diǎn)的專用非標(biāo)焊鉗。
圖2為座椅點(diǎn)焊項(xiàng)目中為適應(yīng)工件特制的焊鉗。該焊鉗的固定極和活動(dòng)極經(jīng)過反復(fù)修改和驗(yàn)證后，能夠滿足該工件所有焊點(diǎn)的需要。
