【正文】 nt, and low efficiency, high error rate, and not sharing information and data, tools and the use of state can not track the life cycle, are unable to meet the current information management needs. With actual production, we have to establish a workshop tool for the threedimensional tool storage system to meet the knife workshop with auxiliary storage and management needs. The system uses optimization technology, a large number of puter storage inventory information, timely, accurate, and prehensive tool to reflect the inventory situation. The entire system uses a graphical interface, manmachine dialogue tips from the Chinese menu, select various functions can be realized and the importation of all kinds of information. Management system using online help function. Through the workshop management, work management and sharing of information. Have automated inventory management, warehousing management tool, a tool for the management and statistical functions. ponents and control structure The entire system, including the structure and electrical machinery control systems. structure and working principle Tool from the stent, drive, drive system, Turret, shielding, control system, and electrical ponents. Support from the column, beam, the upper and lower guide Central track, and track support ponent. 1) Drive for the system chosen VVVF method. Cone used brake motors, with VVVF by Cycloid reducer through sprocket drive. 2) Drag a variable frequency drive system and control technology. VVVF adopted, will speed drive shaft in the normal range adjustment to control the speed rotary turret to 5 ~ 30mm in, the drive shaft into two, two under through sprocket, the two profiled rollers Chain driven rotating shelves. Expansion chain adopted by the thread tight regulation swelling, swelling the regular way. Conditioned, under the same chainofconditioning, so that the chain of uniform. 3) Turret and shields the entire total of 14 independent Turret. 13 of them as a socketTurret, as a drawerTurret, each Turret back through the pin and, under the conveyor chain link chain plate, installed at the bottom roller, chain driven rotating turret rotation along the track. OutletTurret and BT50BT40 Turret Turret two kinds of forms. To strengthen management, security, landscaping modeling, shelf peripherals and shields. Turretdrawer drawer placed at six other Des Voeux a knife, can be categorized with some of knife auxiliary equipment, such as bits, such as turning tools. Control System This tool storage systems is the main electrical control their shelves for operational control and position control. Operational control equipment, including operation of the start of braking control. Position Control is the main location and address of the shelves for testing. Control system as shown in Figure 1. 圖 1 Tool Control System for the 1) Electric Transmission horizontal rotary tool storage systems are the mechanical movements are repeated shortterm work system. And the runtime system needs some speed, speed transmission needs, the system will use VVVF method can be used simple structure, reliable operation of the motor and frequency inverter. 2) Control of the system is divided into two kinds of manual control and automatic control, manual control as a general reserve and debugging methods of work。 Next, ATC, will be replaced with the cutter knives were unloaded into the spindle and tool: Finally, back to the original ATC, standby position. At this point, ATC pleted procedures to continue to run. This ATC, the main advantage of simple structure, the less movement, fast tool change. The main disadvantage is that knives must be kept in parallel with the axis of the plane, and after the home side pared to the tool, chip and liquidcutting knife into the folder, it is necessary to the tool plus protection. Cone knife folder on the chip will cause ATC error, or even damage knife folders, and the possibility of spindle. Some processing centre at the transfer, and the tool side. When the ATC mand is called, the transfercutter knives will be removed, the machine go forward, and positioning with the ATC, in line with the position. 180 186。 刀具及其元件庫存是現(xiàn)代生產(chǎn)管理中的重要環(huán)節(jié) , 特別是大型車間管理。 整個(gè)系統(tǒng)包括機(jī)械結(jié)構(gòu)及電氣控制系統(tǒng)。調(diào)節(jié)時(shí)上、下鏈條松度調(diào)節(jié)一致 , 使鏈條受力均勻。位置控制主要是對(duì)貨架位置和地址進(jìn)行檢測(cè)。 刀庫的作用是儲(chǔ)備一定數(shù)量的刀具，機(jī)械手實(shí)現(xiàn)主軸上刀具的互換 }zs}a 刀具的類型有盤式刀庫、鏈?zhǔn)降稁斓榷喾N形式，刀庫的形式和容量要根據(jù)機(jī)床的工藝范圍來確定。 (3)鏈?zhǔn)降稁? 包括單環(huán)鏈和多環(huán)鏈，鏈環(huán)形式可有 多種變化，見圖 )~c)，基本結(jié)構(gòu)見圖 2. 8do 特點(diǎn) :適用于刀庫容量較大的場(chǎng)合，所占的空間小，一般適用于刀具數(shù)在 30120 把。 (1)順序選擇將刀具按加工工序的順序，依次放入刀庫的每一個(gè)刀座內(nèi)。刀庫上裝有位置檢測(cè)裝置，可獲得每個(gè)刀套的位置。這種方式需要足夠的液壓動(dòng)力和電磁閥刀庫旋轉(zhuǎn)速度可通過節(jié)流閥調(diào)整。圖 所示為螺旋升降式四方刀架 。換刀裝置回轉(zhuǎn)的同時(shí)，刀具庫重新調(diào)整其位置，以接受從主軸取下的刀具 。 180186。完成換刀。換刀時(shí)，先在刀庫中選刀，再由換刀裝置從刀庫或主軸上取刀，進(jìn)行交換，將新刀裝入主軸，舊刀放回刀庫。加工中心的計(jì)算機(jī)數(shù)控裝置 (CNC)發(fā)出的選刀指令，將刀庫轉(zhuǎn)到所需刀具號(hào)的取刀位置，稱自動(dòng)選刀。每把刀具 (或刀座 )均編上代碼，自動(dòng)換刀時(shí)，刀庫旋轉(zhuǎn)，每把刀具都經(jīng)過“刀具 識(shí)別器”接受識(shí)別。編碼環(huán)直徑有大小直徑兩種，分別表示二進(jìn)制的“ 1”和“ 0，通過這兩個(gè)圓環(huán)的不同排列，可以得到一系列代碼。這種方式有編碼鑰匙、編碼卡片、編碼桿和編碼盤等，其中應(yīng)用最多的是編碼鑰匙。對(duì)刀座編碼，刀具編碼，并將刀具放到與其號(hào)碼相符的刀座中。隨機(jī)選刀必須對(duì)刀具編碼，以便識(shí)別。但刀庫中每把刀具在不同的工序中不能重復(fù)使用，如果刀具不按順序裝在刀庫中，將會(huì)產(chǎn)生嚴(yán)重的后果。刀庫內(nèi)數(shù)量較大，因而能滿足復(fù)雜零件的多工序加工，大大提高生產(chǎn)率。 此時(shí)，刀庫容量大，刀具可以較重，常常附加運(yùn)輸裝置來完成刀庫與主軸之間刀具的運(yùn)輸。但由于受空間位置的限制，主軸數(shù)目不能太多，通常只適用于工序較少、精度要就不高的機(jī)床，如數(shù)控鉆床、數(shù)控銑床等。主要缺點(diǎn)是刀具必須存放在與主軸平行的平面內(nèi)，與側(cè)置后置刀具庫相比，切屑及切削液易進(jìn)入刀夾，因此必須對(duì)刀具另加防護(hù)。與此同時(shí)，刀具庫運(yùn)動(dòng)到適當(dāng)位置，換刀裝置回轉(zhuǎn)并同時(shí)與主軸、刀具庫的刀具相配合 。 ,特點(diǎn)和適用范圍 自動(dòng)回轉(zhuǎn)刀架 是數(shù)控機(jī)床上使用的一種簡單的自動(dòng)換刀裝置，有四方刀架和六角刀架等多種形式，回轉(zhuǎn)刀架上分別安裝有四把、六把或更多的刀具，并按數(shù)控指令進(jìn)行換刀。在梯形圖中根據(jù)指令的 T 碼進(jìn)行運(yùn)算比較后輸出角度和速度指令到刀庫伺服驅(qū)動(dòng)刀庫
