5、tem, features a single comparison, the knife only has to find the tool knife, knife positioning the shortest path, axis tool change, but does not support large-scale tool. Automatic knife in the knife election, in the computer memory knife-election on the basis of using the Siemens 840 D features, a

6、nd the election procedures knife more concise, and complete the space Daotao View. ATC use the knife rapid completion of STEP-7 programming, and have been tested in practice. In the positioning of the knife, PLC controlled modular design method, which future production of similar machines will be ve

7、ry beneficial, it is easy to use its other machine. Automatic tool change systems will be faster growth, reduced tool change time, increase the positioning accuracy tool is an important means to help NC technology development. Tool and inventory components of modern production is an important link i

8、n the management, especially for large workshop management. The traditional way of account management, 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

9、 actual production, we have to establish a workshop tool for the three-dimensional tool storage system to meet the knife workshop with auxiliary storage and management needs. The system uses optimization technology, a large number of computer storage inventory information, timely, accurate, and comp

10、rehensive tool to reflect the inventory situation. The entire system uses a graphical interface, man-machine 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 worksh

11、op management, network management and sharing of information. Have automated inventory management, warehousing management tool, a tool for the management and statistical functions.1.System components and control structureThe entire system, including the structure and electrical machinery control sys

12、tems.1.1.1Mechanical structure and working principleTool from the stent, drive, drive system, Turret, shielding, control system, and electrical components. Support from the column, beam, the upper and lower guide Central track, and track support component. 1) Drive for the system chosen VVVF method.

13、 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 thr

14、ough 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 chain-of-conditioning, so that the chain of uniform. 3) Turret and shields the entire total of 14 independen

And the run-time system needs some speed, speed transmission needs, the system will use VVVF method can be used simple structure, reliable operation of the mo

19、tor 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; ways to the system control computer (IPC) and the control unit (inverter contactor , etc.) consisting of a contro

20、l system. 3) location and positioning accuracy of the system automatically identify the site and location using a detection device as proximity switches, relays through the plate-point isolation and the number plate recorded close to the switching signal acquisition and operation of Hutchison with a

21、 Optimal Path addressable identify the current location and shelves of the purpose of the shelf location. In order to enable a more accurate positioning system, adopted two photoelectric switches, to detect the two shelves of the two films.1.2.The functions of the knifeknife The is the role of reser

22、ves a certain number of tools, machine tool spindle in hand to achieve the fungibility a disc cutter knife is the type of library, the chain knives, and other means, in the form of the knife and capacity according to the Machine Tool to determine the scope of the process.1.3.Common typesThe knife is

23、 a tool storage devices, the common knife mainly in the following forms: (1) the turret knife Including the first level turret vertical turret and the first two, see Figure 2.6 a) and b):(2) the disc cutter Disc knife in the library with discoid knife, cutting tool along See how vertical arrangement

24、 (including radial and axial from knife from knife), along See how radial array into acute or arranged in the form of the knife. Simple, compact, more applications, but are ring-cutter, low utilization of space. Figure 2.7 a) to c). If the knife storage capacity must be increased to increase the dia

25、meter of the knife, then the moment of inertia also increased correspondingly, the election campaign long knife. Tool number not more than 32 general. Cutter was multi-loop order of the space utilization knife, but inevitably given the knife from complex institutions, applicable to the restricted sp

26、ace Machine Tool storage capacity and more occasions. Two-disc structure is two smaller capacity knife on both sides of the sub-spindle place, more compact layout, the number of certificates corresponding increase knife, apply to small and medium-sized processing center.(3) the chain knife Including

27、 single-and multi-ring chain ring chain, chain link can take many forms change, see Figure 2.8 a) to c), the basic structure shown in Figure 2. 8 do Features: knife apply to the larger capacity of the occasion, the space of the small number of generally applicable to the tool in the 30-120. Only inc

28、rease the length of the chain tool will increase the number should not be increased circumferential speed of its moment of inertia of the knife does not increase the disc as large.(4) linear combination knife and the knife library The linear knife simple structure in Figure 2.9, tool single order, t

29、he capacity of small knife, used for CNC lathe and drill press on. Because the location of fixed knife, ATC completed action by the spindle without manipulator. The cutter knife is generally the turret combination turret with a combination of the disc cutter knife and the chain combination. Every si

30、ngle knife the knife certificates of smaller, faster tool change. There are also some intensive drum wheel, and the lattice-type magazine for the knife, the knife-intensive though. Small footprint, but because of structural constraints, basically not used for single processing center, the concentrat

31、ion used for FMS for the knife system.1.4 Tool storage capacityTool storage capacity of the first to consider the needs of processing, from the use of point of view, generally 10 to 40 knives, knife will be the utilization of the high, and the structure is compact.1.5 Tool options(1) choose to order

32、 processing tool according to the order, followed Add to the knife every knife in the Block. Each tool change, the order of rotation of a cutter knife on location, and remove the need knives, has been used by the cutter knife can be returned to the original Block, can also order Add Block, a knife.

33、However, as the knife in the tool in different processes can not be repeated use of the knife must increase the capacity and lower utilization rate. (2) most of the arbitrary choice of the current system of using arbitrary NC election knives, divided into Daotao coding, coding and memory-cutter, thr

34、ee. Daotao coding tool code or knives or Daotao need to install the code used to identify, in accordance with the general principle of binary coding coding. Tool knife election coding method uses a special knife handle structure, and each of the coding tool. Each of the tool has its own code, thereb

35、y cutting tool can be in different processes repeatedly used, not to replace the tool back at the original knife, the knife capacity can be reduced accordingly. Memory-election this paper knife, in this way can knives and knife in the position corresponding to the Daotao memory of the PLC in the NC

36、system, no matter which tool on the Inner knife, tool information is always there in mind, PLC . On the knife with position detection devices, will be the location of each Daotao. This tool can be removed and sent back to arbitrary. On the knife is also a mechanical origin, every election, the neare

37、st knife selection. 1.6. Control of the knife (1) the knife as a system to control the positioning axis. In the ladder diagram in accordance with the instructions for computing T code comparison of the output angle and speed of instructions to the knife the knife servo drive servo motor. Tool storag

38、e capacity, rotation speed, and / deceleration time, and other system parameters can be set in such a manner free from any outside influence positioning accurate and reliable but the cost is higher. (2) knife from the hydraulic motor drives, fast / slow the points, with proximity switches count and

39、positioning. In comparison ladder diagram of the current storage system knife (knife spindle) and goals knife (pre-knife) and computing, then output rotation instructions, judging by the shortest path rotation in place. This approach requires sufficient hydraulic power and electromagnetic valve knif

40、e the rotational speed can be adjusted through the throttle. But over time may be oily hydraulic, oil temperature and environmental factors impact the change in velocity and accuracy. Not generally used in large and medium-sized machine tool change frequently. (3) the knife from AC asynchronous moto

41、r driven cam mechanism (Markov institutions), with proximity switches count, which means stable operation, and generally accurate and reliable positioning cam used in conjunction with a mechanical hand, ATC fast-positioning.2. ATC, the main types, characteristics, and the scope of application2.1 Aut

42、o Rotary ToolRotary Tool automatically on the use of CNC machine tool is a simple installation of automatic tool change, the Quartet and 47.60 Turret Tool various forms, such as rotary turret were installed on four, six or more of the Tool , NC instructions by ATC. Rotary Tool has two vertical and h

43、orizontal, relatively simple structure, applicable to economic CNC lathe. Rotary Tool in the structure must have good strength and stiffness, resistance to bear rough Cutting Tool in the cutting force and reduce the role of deformation and improve processing accuracy. Rotating Tool to choose reliabl

44、e positioning programme structure and reasonable position, in order to ensure that each rotary turret to a higher position after repeated positioning accuracy (typically 0.001 to 0.005mm). Figure 2.1 shows the spiral movements of the Quartet Turret.Auto Rotary Tool in the simplest of ATC, is 180 rot

45、ary ATC devices, as shown in Figure 2.2 ATC instructions received, the machine control system put ATC spindle control to the designated location at the same time, the tool movement to the appropriate location, ATC, with the rotary axis and at the same time, the knives matching tool; drawbars from Sp

46、indle Cutting Tools rip, ATC, will be the tool from their position removed; ATC, 180 rotary tool spindle and the tool and tool away; ATC, the Rotary At the same time, the tool refocusing its position to accept Spindle removed from the cutting tool; Next, ATC, will be replaced with the cutter knives

47、were unloaded into the spindle and tool: Finally, back to the original ATC, standby position. At this point, ATC completed 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 parall

48、el with the axis of the plane, and after the home side compared to the tool, chip and liquid-cutting 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 c

49、entre at the transfer, and the tool side. When the ATC command is called, the transfer-cutter knives will be removed, the machine go forward, and positioning with the ATC, in line with the position. 180 Rotary ATC devices can be used horizontal machine, can also be used for vertical machining centers.2. 2 ATC head-turret installedWith rotating CNC machine tool often used such ATC devices, with a few turret head spindle, each with a spindle on both
