【正文】 achine hand then exchange position insert the new knife into the principal axis the old knife puts back a knife databaseThe knife database that deposits knife to have has bigger capacity its capacity has for six knifes adopting the dish form structure the left side that installs in the tool machine signs pillar upThe XKA5032 AC number controls the sign type working panel lifter miller shape and other function parameter etcs to all change the knife with THK6363 typeses automatically number to control the boring miller likeness so this tool machine changes the knife the design of the device to change the knife in the wake of THK6363 typeses automatically automatically the number control the boring miller to change the knife device the design beeses the adoption stalk toward the drum dish type knife database form and the turnover type double the arm machine hand for place to constitute The knife has to press to schedule to the work preface insert the knife of the knife database order of sequence usage turn to take knife position in orderThe knife for using puts back the original knife inside can also press to process sequence to put into the next knifeThat method doesnt need the knife to identify device driving a control also more simple work credibilityBut the knife database in each knife have in the different work preface and cant repeat an usage for satisfying to process to need to only increase the capacity of the quantity and the knife database that the knife have this utilization that lowers knife to have with the knife databaseHave to be very careful while packing knife in addition if the knife doesnt in order have to pack in the knife database will produce serious resultSequences choosing knife is before process will process the knife that spare parts need to have to request to be one by one in order in the knife set of insert the knife database according to the craft the sequence cant have mistakeProcess adjust knife in orderSuit to process a batch quantity to pare greatlythe work piece the species quantity less of mediumsmall scaled the auto change the knife deviceCan know the number controls miller to use 4 make the knife plete most milling and can pare to processSo this capacity is 6 knife databases of knifes almost the nonentity process to need to make use of the circumstance that the knife have again in the process so the knife have of the choice method assurance for in proper order choice the knife have Two hands are mutual perpendicular of the advantage of the turnover type single arm hands machine hand change the knife action credibility changing good time short the weakness is the haft accuracy to have high request structure plications the linking machine adjust of the related accuracy have high request the machine hand leaves to process area nearerGenerally speaking this kind of machine hand useds for the knife database knife the stalk line and the tool machine principal axis stalk line perpendicular the knife database has a form to change the knife device automatically toward the access knife for the path therefore can adopt this kind of machine hand form in the XKA5032 AC number

數(shù)控立式升降臺銑床自動換刀裝置刀庫式的設(shè)計刀庫式的自動換刀裝置是由刀庫和刀具交換裝置換刀機械手組成它是多工序數(shù)控機床上應(yīng)用最廣泛的換刀裝置其整個換刀過程比較復(fù)雜首先把加工過程中需要使用的全部刀具安裝在標準的刀柄上在機床外進行尺寸預(yù)調(diào)后 按一定的方式裝入刀庫換刀時先在刀庫中進行選刀由機械手從刀庫和主軸上取出刀具然后交換位置把新刀插入主軸舊刀放回刀庫存放刀具的刀庫具有較大的容量其容量為六把刀具采用盤形結(jié)構(gòu)安裝在機床的左側(cè)立柱上因為 XKA5032AC 數(shù)控立式升降臺銑床外形及其他性能參數(shù)等均與 THK6363 型自動換刀數(shù)控鏜銑床相似所以本機床的自動換刀裝置的設(shè)計將仿效 THK6363 型自動換刀數(shù)控鏜銑床換刀裝置設(shè)計成采用軸向放置的鼓盤式刀庫形式和回轉(zhuǎn)式雙臂機械手組成 刀具按預(yù)定工序的先后順序插入刀庫的刀座中使用時按順序轉(zhuǎn)到取刀位置用過的刀具放回原來的 刀座內(nèi)也可以按加工順序放入下一個刀座內(nèi)該法不需要刀具識別裝置驅(qū)動控制也比較簡單工作可靠但刀庫中每一把刀具在不同工序中不能重復(fù)使用為了滿足加工需要只有增加刀具的數(shù)量和刀庫的容量這就降低了刀具和刀庫的利用率此外裝刀時必須十分謹慎如果刀具不按順
