One, dig of overview dragon door is a kind of general-purpose large machine tool. Regard 5 kinds of the most primary treatment as one of means, planer is applied extensively at plane to machine a domain, at present most machine tool (include: The boring of planer, lathe, milling machine, be born, machine that note model) lathe bed treatment should use this kind of machine tool. The circuit design of inchoate dragon door dig basically uses traditional generation set + dc motive form. Because efficiency of this kind of circuit is extremely low, noise is very big also, had been washed out as the development hair of electronic technology, those who replace is system of switch magnetoresistive timing and dc timing system. Compare with photographs of afore-mentioned two kinds of systems, our communication asynchronous servo is on function excel they, there also is definite advantage on the price, the PLC function that our oneself relies on on the function can realize the compositive control to dominating circuit. 2, functional brief introduction has simple and easy PLC function as a result of days servo controller, realized the compositive control of milling machine of dragon door dig thereby. A servo, the system of mill of dragon door dig that is an a complete set of, bring huge to go to the lavatory to the client. A) workbench moves: Positive and negative of control workbench electric machinery moves, implementation dot is moved, automatic positive and negative moves. B) feed control: Can control mechanical box feed, delay time feed according to mechanical need, and servo feed orgnaization. C) carry fall knife control: Workbench to when moving, fall knife, when moving reversely, carry knife. D) crossbeam rises fall control: Those who control crossbeam litre fall, those who include beam litre fall after locking movement and beam drop, the relaxation of movement, beam promotes an action instead. 3, ① of performance dominant position is energy-saving fall a confusion of voices uses days asynchronous servo, OK and effective economic electric energy reduces noise. After using days servo, electric machinery efficiency can raise 90% above, and noise is far be less than dc system and switch magnetoresistive system. Servo of strong days of ② overload ability can realize electric machinery rated rotate speed is 2 times more the following overload, make cutting power greater, move faster smoother. Accurate control makes concussion phenomenon won't appear when inverting. Speed ratio of servo of wide days of ③ speed ratio is more than 1: 2000, can be in thereby simplify the requirement that dig mill realizes to grind unifinication below the premise that rigid structure designs, simplify mechanically to still can avoid mechanical and creeping appearance effectively. Nextpage ④ can realize full closed-loop control of the position without commutator servo electric machinery, offerred a condition to do not have commutator to control thereby, when using, need only first the front of workpiece of set good treatment and back end can, reduced the labor intensity of jockey. ⑤ simple and easy PLC controls days servo to have function of simple and easy PLC, use servo but the control that process designing function realizes pair of whole machine tools, include to carry fall knife, intermittent, fast feed, and litre of demote of crossbeam. Realize compositive control truly. 4, circuit hookup (because blueprint can provide sketch map only according to mechanical change) detailed sees electric principle pursues 5, client application is current the controller of my company has been in company of production of milling machine of dig of door of much home dragon to be able to apply successfully, apply extensively at the circumstance that dragon door dig transforms.
