Description
Technical field
The invention belongs to motor fields, and in particular to a kind of ball-screw slide unit control system.
Technical background
Ball-screw is that rotary motion is converted into linear motion or is the preferable of rotary motion by transform linear motion
Product.Ball-screw is actuated element most-often used on toolroom machine and precision optical machinery, and major function is to turn rotary motion
It changes linear movement into or torque is converted into axial repeated action power.Compared with hydraulic pressure moving platform and trapezoidal tooth mechanical skid plateform, ball
Screw slide has both the small and efficient feature of high-precision, invertibity, frictional resistance, is widely used in various industrial equipments
And precision instrument.PLC is commonly used for the control of numerically-controlled machine tool.Important transmission parts --- ball as feed mechanism in lathe
Leading screw, control accuracy and response speed will influence the efficiency of entire lathe.Rely on the technology of PLC and frequency converter, energy
Enough SERVO CONTROLs for realizing ball-screw well.
The content of the invention
To solve the above-mentioned problems, it is an object of the invention to provide a kind of ball-screw slide unit control system, the present invention
Purpose using following technical scheme realize：
A kind of ball-screw slide unit control system is opened including motor, the first limit switch, slide unit, leading screw, the second /V
Pass, encoder, the first optoelectronic switch, the second optoelectronic switch, it is characterised in that：Motor drives leading screw to rotate, and slide unit is followed by silk
Thick stick moves, and encoder measures the rotating speed of motor by the speed that leading screw rotates, and can feed back to motor, and control motor is adjusted in real time
Speed.
Preferably, first limit switch and the second limit switch can limit the movement of slide unit, when slide unit moves to
Motor rotates backward during the two switches；
Preferably, first optoelectronic switch and the second optoelectronic switch are used for determining the position of slide unit, when slide unit is by the
When one optoelectronic switch or the second optoelectronic switch, change the speed of slide unit；
Compared with prior art, the beneficial effects of the present invention are：
The ball-screw slide unit Control System Design of the present invention forms a feedback by the encoder of design, effectively carries
The performance of motor control control has been risen, has improved the control accuracy and response speed of motor servo control.
Description of the drawings
Fig. 1 is ball-screw slide unit control system architecture schematic diagram of the present invention；
Specific embodiment
In the following, with reference to attached drawing and specific embodiment, the present invention is described further：
A kind of ball-screw slide unit control system, including motor 1, the first limit switch 2, slide unit 3, leading screw 4, the second /V
Switch 5, encoder 6, the first optoelectronic switch 7, the second optoelectronic switch 8, motor 1 drive leading screw 4 to rotate, and slide unit 3 is followed by leading screw 4
Movement, 2 and second limit switch 5 of the first limit switch can limit the movement of slide unit 3, when slide unit 3 moves to the two
Motor rotates backward during switch, slide unit counter motion；First optoelectronic switch, 7 and second optoelectronic switch 8 is used for determining slide unit 3
Position, when 3 positive movement of slide unit pass through the first optoelectronic switch 7 when, accelerate, afterwards by the second optoelectronic switch 8 when, subtract
Speed movement；When 3 counter motion of slide unit pass through the second optoelectronic switch 8 when, accelerate, afterwards by the first optoelectronic switch 7 when, subtract
Speed movement.Encoder 6 measures the rotating speed of motor 1 by the speed that leading screw 4 rotates, and can feed back to motor 1 afterwards, pass through PID
1 real-time governing speed of motor is controlled, when the speed of setting is bigger than the speed that encoder 6 is measured, motor 1 is reduced by PID
Speed when the speed of setting is smaller than the speed that encoder 6 is measured, increases the speed of motor 1 by PID.
