夾具設計外文翻譯

1、夾具設計應符合以下基本要求（1）有適當?shù)木群统叽绶€(wěn)定性夾具體上的重要表面，如安裝定位元件的表面、安裝對刀和導向元件的表面以及夾具體的安裝基面（與機床相連接的表面）等，應有適當?shù)某叽绾托螤罹?，它們之間應有適當?shù)奈恢镁?。為使夾具體尺寸穩(wěn)定，鑄造夾具體要進行時效處理，焊接和鍛造夾具體要進行退火處理。（2）有足夠的強度和剛度。加工過程中，夾具體要承受較大的切削力和夾緊力。為保證夾具體不產(chǎn)生不允許的變形和振動，夾具體應有足夠的強度和剛度，因

2、此夾具體需要有一定的壁厚。（3）結(jié)構工藝性好。夾具體應便于制造、裝配和檢驗。鑄造夾具體上安裝各種元件的表面應鑄出 3～5mm 高的凸面，以減少加工面積。鑄造夾具體壁厚要均勻，轉(zhuǎn)角外應有R3～R5mm 的圓角。夾具體結(jié)構形式應便于工件的裝卸。（4）要有適當?shù)娜菪伎臻g和良好的排屑性能。對于切削時產(chǎn)生切削不多的夾具，可加大定位元件工作表面與夾具之間的距離或增設容屑溝槽，以增加容屑空間；對于加工時產(chǎn)生大量切屑的夾具，可設置排屑缺口或斜面，斜角可

3、取 。 ? ? 50 ~ 30（5）在機床上安裝穩(wěn)定可靠。夾具在機床上的安裝都是通過夾具體上的安裝基面和機床上相應表面的接觸或配合實現(xiàn)的。當夾具在機床工作臺上安裝時，夾具的重心應盡量低，重心越高則支承面應越大；夾具底面四邊應凸出，使夾具體安裝基面與機床的工作臺面接觸良好。接觸邊或支腳的寬度應大于機床工作臺梯形槽的寬度，應一次加工出來，并保證一定的平面精度；當夾具在機床主軸上安裝時，夾具安裝基面與主軸相應表面應有較高的配合精度，并保證夾具

4、體安裝穩(wěn)定可靠。（6）有較好的外觀。夾具體外觀造型要新穎，鋼質(zhì)夾具體需要發(fā)藍處理或退磁，鑄件未加工部位必須清理，并涂油漆。（7）在夾具適當位置用鋼印打出夾具編號，以便于工裝的管理。夾具的制造及工藝性（1）夾具的制造精度夾具通常是單件生產(chǎn)，且制造周期很短。為了保證工件的加工要求，很多The fixture design should meet the following basic requirements(1) the appropri
