XKA5032A/C數控立式升降台銑床自動換刀裝置 論文編號:JX391 論文字數:19362.頁數:37 摘要 本論文介紹的是XKA5032A/C數控立式升降台銑床自動換刀裝置（刀庫式）的設計.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。它是多工序數控機床上應用最廣泛的換刀裝置，其整過換刀過程比較復雜。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調後，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，然後交換位置，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,採用盤形結構,安裝在機床的左側立柱上。因為XKA5032A/C數控立式升降台銑床外形及其他性能參數等均與THK6363型自動換刀數控鏜銑床相似，所以本機床的自動換刀裝置的設計將仿效THK6363型自動換刀數控鏜銑床換刀裝置，設計成採用軸向放置的鼓盤式刀庫形式和回轉式雙臂機械手組成。 刀具按預定工序的先後順序插入刀庫的刀座中，使用時按順序轉到取刀位置。用過的刀具放回原來的刀座內，也可以按加工順序放入下一個刀座內。該法不需要刀具識別裝置，驅動控制也比較簡單，工作可靠。但刀庫中每一把刀具在不同工序中不能重復使用，為了滿足加工需要只有增加刀具的數量和刀庫的容量，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，如果刀具不按順序裝在刀庫中，將會產生嚴重的後果。順序選刀是在加工之前，將加工零件所需刀具按照工藝要求依次插入刀庫的刀套中，順序不能有差錯。加工時按順序調刀。適合加工批量較大、工件品種數量較少的中、小型自動換刀裝置。可知數控銑床用4把刀就可完成大多數的銑削加工。所以這個容量為6把刀的刀庫，幾乎不存在加工過程中需要重復利用刀具的情況，所以刀具的選擇方式確定為順序選擇刀具。 兩手互相垂直的回轉式單臂雙手機械手的優點是換刀動作可靠，換好時間短，缺點是刀柄精度要求高，結構復雜，聯機調整的相關精度要求高，機械手離加工區較近。一般來說，這種機械手用於刀庫刀座軸線與機床主軸軸線垂直，刀庫為徑向存取刀具形式的自動換刀裝置，因此，在XKA5032A/C數控立式升降銑床的自動換刀裝置中可採用這種機械手形式。 關鍵詞：數控銑床；自動換刀裝置；刀庫；換刀機械手 Abstract This thesis introction is the design that the XKA5032 A/C number controls the sign type working panel lifter miller to change the knife device(the knife database type) automatically.The knife database type automatically change the knife device is have by the knife database and the knife to exchange device(change the knife the machine hand) to constitute.It is many work ordinal numbers to control the top of the tool machine to apply to change the knife device most extensively, it is whole to lead to change the knife process more complicated.First process process in need to be use of all knifes have to install on the haft of the standard, pressing certain way to pack into the knife database after the tool machine carry on size to prepare to adjust outside.Be in the knife database carry on choosing knife first while change the knife, is taken out knife to have from the knife database and the principal axis by the machine hand, then exchange position, insert the new knife into the principal axis, the old knife puts back a knife database.The 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 up.The XKA5032 A/C number controls the sign type working panel lifter miller shape and other function parameter etc.s 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 becomeses the adoption stalk toward the drum dish type knife database form and the turn-over type double the arm machine hand for place to constitute. The knife has to press to schele to the work preface insert the knife of the knife database order of sequence, usage turn to take knife position in order.The knife for using puts back the original knife inside, can also press to process sequence to put into the next knife.That method doesn't need the knife to identify device, driving a control also more simple, work credibility.But the knife database in each knife have in the different work preface and can't 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 database.Have to be very careful while packing knife in addition, if the knife doesn't in order have to pack in the knife database, will proce serious result.Sequence's 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 can't have mistake.Process adjust knife in order.Suit to process a batch quantity to compare greatly,the work piece the species quantity less of medium,small scaled the auto change the knife device.Can know the number controls miller to use 4 make the knife complete most milling and can pare to process.So 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 turn-over 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 complications, the linking machine adjust of the related accuracy have high request, the machine hand leaves to process area nearer.Generally 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 A/C number control the sign type rise and fall miller the auto change the knife the device.

③ 有做過4MN液壓剪液壓剪液壓系統設計，或者相似的畢業設計嗎
我有一整套，可以轉讓，價格有點高。
④ 機械式無切換換向裝置 有誰做過這個畢業設計題目重謝，我是近機類專業的學生
你的意思是說不用換向是嗎 ？ 告訴你一個簡單的思路 可以用換單離合器帶代替的 ，他只通過摩擦片的捏合，不通過齒輪捏合，非常的平穩 ，應該適合你的課題，具體的你可以網上搜索。。
