Description
(1) technical field
The utility model relates to the moving beam gantry boring and milling machine of numerical control, the balance adjusting device of the moving beam gantry boring milling bed beam of particularly a kind of numerical control.
(2) background technology
Moving beam gantry boring and milling machine refers to the lathe that crossbeam (Y-axis) can move up and down along column guide rail (W axle).Crossbeam move up and down the milling altitude range that has strengthened workpiece, but also increased the debugging difficulty of the moving beam gantry boring and milling machine of numerical control.One of its technological difficulties are exactly the balance and the precision adjustment problem of crossbeam, are difficult to so far solve.Beam balance refers to the ram milling head on crossbeam when mobile, because the difference of its position, requires also different to the pressure of two oil cylinders of crossbeam.Need adapt to the demand of ram milling head diverse location according to the pressure that milling head is adjusted left and right sides oil cylinder in real time in the physical location of crossbeam to pressure.The following Fig. 1 of synoptic diagram.When the ram milling head was mobile on crossbeam (Y-axis), with the variation of X1, X2, P1, P2 also must follow real-time adjustment just can keep beam balance, otherwise will cause the crossbeam inclined oversize, influence machining precision.
(3) summary of the invention
The utility model provides the balance adjusting device of the moving beam gantry boring milling bed beam of a kind of numerical control in order to remedy the deficiencies in the prior art.
The utility model is achieved by the following technical solution:
The balance adjusting device of the moving beam gantry boring milling bed beam of numerical control of the present utility model, its special character is: comprise the PLC analog output module, PID control panel, proportioning valve amplifier, proportioning valve, oil cylinder, the pressure transducer that connect successively, the hydraulic pressure transducer output terminal connects the PID control panel, forms a closed-loop control device.PLC is the program logic controller of numerically-controlled machine, outputs to PLC analog output module given as closed-loop control through the result of computing.
The balance adjusting device of the moving beam gantry boring milling bed beam of numerical control of the present utility model, its principle of work be, reads the Y-axis actual calculation of location by PLC and go out set-point and export in real time, given as the PID control panel.Constitute closed-loop control by proportioning valve, pressure transducer and Proportional Valve-controlled making sheet, the openings of sizes of real-time resize ratio valve, the pressure of control oil cylinder reaches the purpose of adjusting beam balance.
The beneficial effects of the utility model are that balance adjustment is effective, has eliminated because the ram milling head moves the pressure difference value that causes along crossbeam, and crossbeam is operated steadily, and effectively avoids occurring the inclined oversize phenomenon.
(4) description of drawings
Below in conjunction with accompanying drawing the utility model is further described.
Accompanying drawing is a structural representation of the present utility model.
Fig. 1 is milling head each several part stressing conditions when mobile on crossbeam, and Fig. 2 is proportioning valve closed-loop control figure.
Among the figure, MG is the weight sum of ram milling head and crossbeam, and P1 is left oil cylinder working-pressure, and P2 is right oil cylinder working-pressure, and X1, X2 are the distance of two oil cylinders of milling head distance.
(5) embodiment
Accompanying drawing 1-2 is a kind of specific embodiment of the present utility model.
The balance adjusting device of the moving beam gantry boring milling bed beam of numerical control of the present utility model, comprise the PLC analog output module, PID control panel, proportioning valve amplifier, proportioning valve, oil cylinder, the pressure transducer that connect successively, the hydraulic pressure transducer output terminal connects the PID control panel, forms a closed-loop control device.
The utility model adopts this proportioning valve of atropic, pressure transducer and Proportional Valve-controlled making sheet (comprising PID plate and proportioning valve amplifier) to realize the closed-loop control of oil cylinder working-pressure, and principle as shown in Figure 2.MG is the weight sum of ram milling head and crossbeam, and P1 is left oil cylinder working-pressure, and P2 is right oil cylinder working-pressure.When crossbeam was moving along y-axis shift, PLC read the physical location of ram milling head in crossbeam (Y-axis) in real time, obtains X1, X2, and is converted to certain numerical value by certain functional relation, outputs to the PLC analog output module.The output voltage of PLC analog output module is given as the PID control panel, the variation of controlled hydraulic pressure simultaneously detects by pressure transducer and is converted to voltage signal, also feed back to PID control panel signal, the PID control panel is made comparisons feedback signal and input signal, the difference of two voltage signals is through handling and computing control ratio valve amplifier.The openings of sizes of the output voltage resize ratio valve of proportioning valve amplifier, realize adjusting automatically continuously of proportioning valve, eliminate, realize the real-time adjustment of oil cylinder working-pressure because the ram milling head moves the pressure difference value that causes along crossbeam, crossbeam is operated steadily, the inclined oversize phenomenon can not occur.
