　　表面處理技術(shù)是勞動(dòng)強(qiáng)度高,加工效率低的工藝之一,針對(duì)于某些特定的表面處理,發(fā)明了機(jī)械錘擊表面處理技術(shù),目的是通過自動(dòng)化工藝,取代工件表面的手工拋光和硬化工序。在制動(dòng)器上,使錘擊球以錘擊運(yùn)動(dòng)到工件表面上。由于偏硬表面的表面處理需求較高,機(jī)械錘擊可以選擇以一種恒定方式而不是傳統(tǒng)方法進(jìn)行工作。另一方面,由機(jī)械錘擊完成的金屬表面不僅提高了表面硬度,而且還可以通過更光滑的表面提高噴丸效率。機(jī)械錘擊的目標(biāo)是構(gòu)建一個(gè)能夠比以前更好地抵抗疲勞的表面層。所以本文的研究將著重探索以下特點(diǎn):首先,簡要介紹了機(jī)械錘擊的工作原理和結(jié)構(gòu),介紹了機(jī)械錘擊的發(fā)展,分析了機(jī)械錘擊對(duì)工業(yè)自動(dòng)化的影響以及智能技術(shù)在未來發(fā)展中的前景。其次,本文將研究不同方法條件下金屬表面層的變化,以優(yōu)化改變硬度和平滑表面層的關(guān)鍵路徑,以獲得更好的表面加工精度。第三,由于所有機(jī)械錘擊過程都具有共同特征,因此存在一些顯著差異,因此本文研究將展示一種新技術(shù)方法,即采用音圈電機(jī)作為執(zhí)行機(jī)構(gòu)的核心部件。借助執(zhí)行機(jī)構(gòu)的直線運(yùn)動(dòng),使碳化鎢錘將在不同的頻率范圍內(nèi)工作,根據(jù)音圈電機(jī)的動(dòng)力增強(qiáng)工件表面層上受控制的擺動(dòng)運(yùn)動(dòng)。第四,機(jī)械錘擊連接數(shù)控銑床進(jìn)行實(shí)驗(yàn)和研...
