I. Overview In many large-scale machine tool equipment (such as: planer, vertical lathe), the tool feed function is very important, which directly determines the processing accuracy of the equipment. Take Gantry planer as an example, currently there are two main ways of the gantry planer function, one is the traditional “mechanical knife box†method, and the other is the more popular “timed knife†method. The first kind of accuracy is not high and expensive. The second type of accuracy is lower, and investment in frequency converters, time relays, etc. must be added to the implementation. In this case, when the planer implements the precision planer, the operator generally adopts a manual feeding method, and each time a knife is taken, a measurement is performed, which greatly reduces the working efficiency. The servo system can be used to solve this problem. However, the servo system usually faces two problems when it is implemented. First, the servo controller and the servo motor are used for high prices; second, the servo system generally requires the control of the upper computer, increasing The cost has increased the technical difficulty.
In response to this situation, Time Technology Co., Ltd. uses a self-developed AC asynchronous servo control system. 32-bit microprocessor can be used for precise speed, position and torque control of asynchronous motors. The most distinctive feature is that it has open PLC function, and no longer depends on the upper computer to work independently and saves cost. The time servo system design is targeted to adapt to all current planer control systems and increase milling and grinding functions. The installation is flexible, and it can directly work with the original circuit. It is suitable for the Longmen planer transformation and stereotyped production enterprises.
With this system, when the tool post is in the continuous working state, it can realize a wide range of speed control, thus achieving the horizontal milling function; when the tool post is in the intermittent working state, it can achieve accurate feed, the precision can reach within 5μ, the feed amount The setting mode is also very flexible. It can be set by analog, digital, jog potentiometer or touch screen; it can be manually adjusted. The MPG function will greatly reduce the labor intensity of workers and the quantitative adjustment is more accurate.
Second, the function introduces the function of time servo servo feed mechanism:
· When the continuous feed function is used, the speed ratio of the optical servo system is greater than 1:5000, and the speed accuracy reaches ±0.02%. The smooth output of the low speed and high torque can easily realize the slow feed of the tool holder to meet the requirements of the milling feed and simplify the past. The design of mechanical high and low gears achieves the requirements of planer and milling machine.
With the quick function of gantry milling, easy milling operation.
· The position control of the intermittent feed function is precise, and the motor positioning accuracy is ±1P (0.036°), which can realize accurate feed control. The feed accuracy can be up to 5μ according to the screw accuracy.
The feed amount setting method is flexible, including analog, digital, jog potentiometers, touch screens, etc., to adapt to a variety of high and low end applications.
· The MPG fine-tuning function has the unique MPG function of the CNC milling machine. The MPG function greatly reduces the operator's labor intensity and improves the accuracy of the milling and planing tools.
Quantitative approach to fine-tune the way to change the previous hand-feed approach, the amount of uncontrollable feed, the MPG control accuracy is divided into 1μ, 10μ, 100μ third gear.
Time servo feed mechanism features:
· Built-in PLC
With internal PLC function, it can work independently as a system, and it is convenient to work with all kinds of gantry planing and milling electronic control systems. When there is inconvenience, you can also modify the program in real time to meet customer requirements.
· Easy to install and use The system simplifies the mechanism of the feed box. It only needs to consider the way of installing ordinary motors.
The basic interface of the time servo feed mechanism: (according to actual changes in machinery)
C4D0: Continuous/Intermittent Select C4D1: Left (This signal's rising edge takes effect when intermittent feed is in progress)
C4D2: Right (rising edge of the signal is active when the feed is intermittent)
C4D3: Fast (only effective at continuous feed, and must be used with direction signals)
C4D4: Increment of feed amount (effective when selecting jog potentiometer to adjust feed amount)
C4D5: Reduced feed amount (effective when jog potentiometer is selected to adjust feed amount)
C5D0: Hand gating (effective in both intermittent and continuous modes)
C5D1: x1 (handle feeds 1μ for each pocket and 10μs for neutral)
C5D2: x100 file (handle pulse corresponding to feed 100μ)
Third, the application of the effect At present, the system has been applied in a number of gantry planer manufacturers, has been widely praised. Time Company also designed a stand-specific tool carrier servo system according to the requirements of a vertical vehicle, and was applied in many manufacturers.
