The control device comprises a servo controller, a servo motor with a rotary encoder, the controlled throttle, a programmable logic controller (PLC) and a principal computer (PC), and the servo controller, the servo motor with the rotary encoder, the controlled throttle, the programmable logic controller (PLC) and the principal computer (PC) are connected. The control device is characterized in that a screw rod driving shaft and a slide block are connected between the servo motor with the rotary encoder and the throttle by a coupling and a flexible shaft; a magnetic switch is arranged on the screw rod driving shaft; and the rotary encoder is connected at the port of the servo controller. The control device has the advantages of simple structure, convenient use, high accuracy, safety and reliability, accurate control, and convenient communication and display; and no matter the throttle is manually controlled or automatically controlled according to a set program, the control device can satisfy requirements of various test programs.
Description
Technical field:
The utility model relates to a kind of control gear, is specifically related to the engine oil controlling device for doors of on the engine testsand throttle of motor being controlled automatically and manually being controlled.
Background technique
Original aircraft engine test stand Throttle Opening Control mainly is a Purely mechanical, hydraulic type or electric actuator mode etc., and the general precision of these control modes is not high, ability to communicate is not enough, it is all right to be used for manually control, but efficient is too low, and the automatic control that is used for throttle is not suitable for.Because precision is not high, can not control accurately the stroke of throttle in the commissioning process automatically, therefore do not satisfy the requirement of test bay technology.
Summary of the invention
The purpose of this utility model is to overcome the deficiency of existing apparatus, provides a kind of simple in structure, and control accurately communication, shows engine oil controlling device for doors easily.
The utility model is by servocontroller, the actuating motor of band rotating coder, throttle, programmable controller (PLC) and upper-position unit (PC) connect to form, it is characterized in that: between the actuating motor of being with rotating coder and throttle, be connected with screw mandrel live axle, slide block by coupling, flexible axle; Described screw mandrel live axle is provided with magnetic switch; The port of described servocontroller is connected to rotating coder.
Slide block drives the flexible axle motion, and flexible axle is finally controlled the actuating length of throttle.By manual rotating coder, encoder sends pulse signal and gives servocontroller, can manually control the action of actuating motor, thereby realizes the manually action of control engine throttle.
The utility model is simple in structure, and is easy to use, and the precision height is safe and reliable, and control is accurate, and communication, demonstration are conveniently manually controlled throttle or by the procedure auto-control throttle of setting, all can be satisfied the requirement of various test run program no matter be.The utility model also has the super protective function of turning round, and actuating motor can stop automatically when super turning round, and has only and removes super turning round when switching on again, just can work on, and this also is the protection to throttle.When manually controlling, control accuracy is by the precision of external rotating coder and the precision decision of screw mandrel.
Description of drawings
Fig. 1 is a structure principle chart of the present utility model.
Fig. 2 is the utility model Fig. 1 circuit theory diagrams.
Embodiment
By accompanying drawing as can be seen, the utility model is with the actuating motor 3 of rotating coder by servocontroller 2, throttle 8, and programmable controller 10 (PLC) and upper-position unit 9 (PC) connect to form.The port of servocontroller 2 is connected to rotating coder 1.The screw mandrel live axle 5 of band slide block 6 is connected with actuating motor 3 by coupling, is driven by actuating motor 3.Screw mandrel live axle 5 with stopper can prevent the engine throttle overtravel.In the lateral groove of screw mandrel live axle 5, the spacing magnetic switch in the left and right sides 4 is housed, and the signal of magnetic switch 4 sends servocontroller 2 to, carries out electric spacing to the left and right sides stroke of slide block 6, guarantee that engine throttle 8 action can overtravel, can not damage engine throttle 8.Servocontroller 2 is from programmable controller 10 (PLC) and upper-position unit 9 (PC
) receive control signal, drive actuating motor 3 operations.Actuating motor 3 receives control command from programmable controller 10 (PLC), upper-position unit 9 (PC) and external rotating coder 1, presses instruction operation.Programmable controller 10 (PLC) and upper-position unit 9 (PC
), by the establishment dedicated program servocontroller 2 is sent operating instruction.Flexible axle 7 one ends link to each other with slide block 6 on the screw mandrel live axle 5, and the other end links to each other with the throttle 8 of motor, and slide block 6 drives flexible axles 7 motions, the actuating lengths of flexible axle 7 final control throttles 8.External rotating coder 1 joins with the private port of servocontroller 2, by manual rotating coder 1, encoder sends pulse signal and gives servocontroller 2, also can manually control the action of actuating motor 3, thereby realizes the manually action of control engine throttle 8.
Control accuracy is determined jointly by rotating coder 1, actuating motor 3, screw mandrel live axle 5.Screw mandrel live axle 5 general repeatabilitys can reach 0.02mm, and rotating coder 1 and actuating motor 3 can make the repetition control accuracy of screw mandrel live axle reach 0.02mm by type selecting, therefore whole automatic control and manually the precision height of control, can accurately control engine throttle 8 actuating lengths, thereby accurately control the oil inlet quantity of motor, satisfy the automatic test run requirement of motor fully.
Upper-position unit 9 has just been read the present position of actuating motor 3 by the information that RC232 reads the rotating coder in the actuating motor 3, just can show the position of throttle 8 by converting on upper-position unit 9 (PC) display device, is convenient to monitor the actual aperture of throttle 8.
