1 foreword comes nearly 20 years, progress as science and technology especially the change of the development of computer technology and social environment element, market competition is more and more intense, the client's demand is higher and higher. The policymaker of manufacturing industry realizes, to win competition, must reach 5 respects such as the service to undertake improvement 〔 in time of product function, delivery, quality, price 1 〕 . Modular design technology can increase product function one kind namely, shorten the advanced products plan method of delivery time. Modular design technology is the unit of same function in the product, the design becomes those who have different utility or property, can the module that crossing-over chooses, the combinative essential factor between each function module is same, can inspect an user to need to assemble a product. The enterprise is used modular design technology, can abound product standards and breed series greatly, the performance that improves a product, quality and the noise to the user should force, get used to the requirement that the product changes quickly. Can solve product breed, norms and design to create the contradiction between cycle well, and deliver the goods cycle weak point, cost is low, make company product has market competition ability more. 2 center lathe are modular the design is forecasted according to market research, technology, we are mature the vitality of the limits of center lathe application and product, of the program that had lathe breed norms and module differentiate. The component that waits for main shaft box, feed box, tool carrier, rear push frame different function is divided into unit of 8 groups of functions, namely 8 module group. Same function unit is single component no longer, have the different structure of different utility or function however, but function and combinative essential factor are same a series of can the module of crossing-over. For example group of module of main shaft box has box of main shaft of limits of fundamental speed change, sheet the module of main shaft box of the use of 7 kinds of different property such as box of fast main shaft, can have exchange; If group of tool carrier module has type of dislocation tool carrier, vertical scroll of painting or calligraphy,turn again the tool carrier module of 6 kinds of different utility such as the tower and structure. The buildup that programme controll module is independence functional module, set module beforehand as what raise level of machine tool automation, the purpose is the vitality that adds a product. These 8 groups of module undertake changing suitably can assorted the lathe of a few kinds of distinct performance characteristics, in order to get used to the different need of the change of the market and user. We are in of center lathe modular 〔 of the following principles abided by when the design 2 〕 : (1) detached principle: the machine tool depart is can satisfy 8 groups of module with a variety of need, sound performance. The module that center lathe designs is specific differentiate as follows: Box of ① main shaft: Box of main shaft of limits of box of box of main shaft of limits of fundamental speed change, main shaft of limits of little speed change, big speed change, adjustable box of gearshift limits main shaft, sheet box of main shaft of double axis of box of fast main shaft, horizontal, vertical. ② feed orgnaization: Feed and car whorl orgnaization, without whorl orgnaization, sheet fast feed orgnaization, diamond bores hole with the bridge, double tool carrier uses quick stroke orgnaization, quick stroke orgnaization. ③ tool carrier: Type of double tool carrier, profile modeling tool carrier, dislocation tool carrier, vertical scroll of painting or calligraphy turns tower, answer round of type tool carrier. ④ rear push frame: Mechanical rear push frame, pneumatic rear push frame, hydraulic pressure rear push frame, bore uses rear push frame, double axis rear push frame. ⑤ clamp device: Device of pneumatic clamp device, hydraulic pressure clamp, electromagnetism clamp device. ⑥ lathe bed: Common lathe bed, double tool carrier uses lathe bed. ⑦ sends ⑧ of 　 of work or material rest automatically programme controll implement pursue 1 those who be center lathe is modular design sketch map (partial module) gave out only in the graph. 1, 2, 3, 4, 5.

Lathe bed pursues of 1 center lathe modular design (2) integrates a principle: Unite module open lathe measure series to have the reasonable dimension, general that accords with our country regulation. The circumstance that differs to suit dimension of all sorts of width of main shaft box for example, by series dimension of lathe bed width cent is: Common lathe bed, double tool carrier uses lathe bed. (3) connection principle: Design the interface element between each module same, in order to ensure the assembly between module precision and connection stiffness, and module repeats the dependability when using. (4) gets used to a principle: To be developed better modular tectonic economic effect, modular Yu Tongmo of design technology incline to piece group cross kind modular tectonic. Milling machine of center lathe, horizontal and vertical drilling machine suit to cross particularly kind modular, graph 2 for identical module group cross kind of tectonic sketch map. Accordingly, combine module random place to require a machine tool to can be satisfied, the method of machine tool construction that spent not may detailed divisional module adopts when the design. Graph 2 identical module group cross kind of tectonic signal 3 programme controll implement design us to be in of center lathe modular use in the design advanced but process designing controller replaces relay to control, in order to implement stand-alone automation. Can making up Cheng controller is the newest achievement of microelectronics technology and small computer technology, have reliability tall, interference rejection sex strong, process designing is agile convenient, low to environmental requirement, bulk small, structure the advantage such as compact, facilitating installation. The F1 that this design uses company of 3 water chestnut to produce, 60MR can make up Cheng controller, undertake dominating interface design and programming to corresponding module respectively. Go all out in module when packing a machine tool, reach interface of concerned model block control its to control a program to assemble rise, form center lathe whole to control a system. The control that module of tower tool carrier turns to be an introduction to be able to make up Cheng controller with respect to type of vertical scroll of painting or calligraphy below is designed. (Type of 1) vertical scroll of painting or calligraphy turns type of vertical scroll of painting or calligraphy of principle of work of system of feed of tower tool carrier turns the ordinal circumgyrate that the working process of tower tool carrier is tool carrier makes cutting tool completes each work treatment. Its feed system is to use implementation of hydraulic pressure system to turn of dislocation of feed of the quick advance and retreat of tower tool carrier, job, tool carrier, tool carrier raise and locking. Its job principle sees a picture 3. 1.

Graph 4 to can make up the control block diagram of Cheng controller. Whole feed system has advance and back down the position of two direction is controlled and quicken feed of advance and retreat, job to exit the control that waits for a variety of speed quickly. The input that needs to be able to make up Cheng controller nods 19 (corresponding X400, X506) , output nods 12 (corresponding Y430, Y533) . Input end receives the pushbutton that comes from center lathe operation panel and switch of bed body journey respectively, output control signal controls hydraulic pressure to dominate the action of a powerful person of of all kinds electromagnetism, turn in order to implement form of vertical scroll of painting or calligraphy the job of tower tool carrier. The input that can make up Cheng controller output allocation sees a picture 5. CNC Milling CNC Machining
