Abstract
The utility model discloses a big moment of torsion mills power device with drilling has big, the easily speed governing of moment of torsion, and wide speed regulating range, small, use reliable, need not lubricated advantage. The utility model discloses a technical scheme do: power main shaft box one side installation servo motor, servo motor passes through servo driver and is connected with lathe numerical control system PLC, and the servo motor main shaft passes through the shaft coupling and is connected with the main shaft, DC power supply is through the variable resistance partial pressure, then connects on the servo driver analog interface, and lathe numerical control system PLC is just reversing signal output part and is passing through auxiliary relay and servo driver input ports are connected. Because servo motor is small, the moment of torsion is big, traditional asynchronous machine is bulky, the moment of torsion is little, difficult installation. The utility model discloses a servo motor be convenient for realize the rotary speed control, and the moment of torsion is great as the main shaft. Servo motor still has wide speed regulating range, facilitates the use reliably, need not advantages such as lubricated safely.
Description
Technical field
The present invention relates to one kind is applied to middle-size and small-size numerically controlled lathe, the high pulling torque milling of complex milling machine tool and drilling are moved
Power apparatus.
Background technology
Power milling and drill unit are that numerical-control turn-milling is combined requisite modular construction, because digital control system is controlled
The number of axle limited although general asynchronous machine is easily controllable, but if using general asynchronous motor, then can run into body
Long-pending huge, moment of torsion is little, not easy to install it is impossible to the trouble such as governing speed.
Content of the invention
The purpose of the present invention is in the case that digital control system controls the number of axle limited, realize a kind of moment of torsion big it is easy to speed governing,
And speed-regulating range width, small volume, safe ready, using reliability, need not lubricate, the milling of the electromechanical integration being easily installed and brill
The power set cut.
For achieving the above object, the technical solution used in the present invention is：
A kind of high pulling torque milling and the power set of drilling, servomotor, servomotor are installed in power spindle casing side
It is connected with machine tool numerical control system PLC by servo-driver, servomotor spindle is connected with main shaft by shaft coupling；
Dc source, through variable resistance partial pressure, is then connected on servo-driver analog interface, machine tool numerical control system
PLC rotating signal output part is connected with servo-driver input port by auxiliary reclay.
According to the power set of described high pulling torque milling and drilling, the encoder of servomotor and the volume of servo-driver
Code feedback port connects.
According to the power set of described high pulling torque milling and drilling, machine tool numerical control system PLC rotating signal output part
Mouthful Y0.5, Y0.6 are connected with DC24V end by auxiliary reclay KA1, KA2 respectively, two auxiliary reclay normally opened contacts and in
Between relay connect, machine tool numerical control system PLC input X1.7 is connected with DC24V end by auxiliary reclay KA2 normally-closed contact.
Diode is all parallel with two described auxiliary reclays, described diode cathode is all connected with DC24V end.
Because servomotor small volume, moment of torsion are big, conventional asynchronous motor volume is huge, moment of torsion is little, not easy to install.The present invention
Using servomotor as main shaft, facilitate implementation rotating speed control, and moment of torsion is larger.Servomotor also has speed-regulating range width, peace
Full convenient use is reliable, the advantages of need not lubricate.

As shown in Figure 2, servo-driver is connected with servomotor, servo-driver and digital control system PLC connection
As described below.
Dc source, through variable resistance partial pressure, is then connected on servo-driver analog interface, machine tool numerical control system
PLC rotating signal output port Y0.5, Y0.6 are connected with DC24V end by auxiliary reclay KA1, KA2 respectively, continue in centre
Diode is parallel with electrical equipment, machine tool numerical control system PLC input X1.7 passes through auxiliary reclay KA2 normally-closed contact and DC24V
End connects.
The encoder of servomotor is connected with the encoder feedback port of servo-driver.The simulation being provided with variable resistance
Voltage V-REF is directly connected on the analog interface of servo-driver, changes the numerical value of analog voltage, just can change servo unit
Control the size of output motor speed.Servomotor positive direction and reciprocal rotating signal, at machine tool numerical control system PLC
Reason, exports auxiliary reclay, auxiliary reclay normally opened contact is connected on servo-driver port.In addition motor encoder must
Servo-driver must be connected, the encoder of servomotor is as speed feedback device.
