Specific embodiment
Below with reference to the accompanying drawings and in conjunction with the embodiments, to describe the present invention in detail.
With reference to shown in Fig. 1, Fig. 3, determine torque servo amplifier, including motor 5, described
Motor 5 two ends are connected with bearing 2, and described bearing 2 is fixed on fixed stand 3, described solid
Determine pallet 3 and be connected with fixed part 8；Described motor 5 one end is connected with rotary shaft 1, another
End is connected with the card 4 that stops the rotation, and the described card 4 that stops the rotation is provided with load cell 6,
Described rotary shaft 1 one end is connected with speed probe 7.
Shown in reference Fig. 2, further, described load cell 6 and described revolution speed sensing
Device 7 is connected to CPU by wire.
Further, described CPU is connected with PWM power supply by wire.
Further, described load cell 6 is load cell.
Further, described fixed stand 3 is housing.
Described load cell 6 and described speed probe 7 measure simultaneously.
With reference to shown in Fig. 4, the thin film of drum sends machine, the application on wrapping machine, also
Additional measuring diameter electronic loop is had to enable to keep stablizing of tension force.
The thin film of drum sends machine, and for wrapping machine, submitting portion keeps same isostension,
So the torsion of axle and the diameter of drum can be measured, then calculate tension force, make tension force steady
The fixed strength controlling brake.
Wrapping machine measures torsion and drum diameter, then calculates tension force.Allow tension stability, control
The electric current of motor processed.
If comparing with existing mode, it is equal for sending machine and the tension force of wrapping machine, stable
Control, thus thin film transport will not occur thin film relax, with do not need benefit
Just lax mechanism and Wai Hang mechanism.
During application wrapping machine, stable tension force carrys out very neat wound wire.The speed of power transmission line
It is to maintain stable, so the rotary speed of bobbin is high-speed rotation when just starting.Gradually slow
Rotary speed, so the translational speed of bobbin becomes inverse proportion bobbin rotary speed.
If arm tensioning mode before relatively, principle tension variation, institute will not occur
So that torsion bigger than normal can be set, spiral amount can be increased.
With reference to shown in Fig. 5, connect motor and this equipment, rotation motor is stopping the rotation
The load capacity of the corresponding brake torsion on card, measures this load capacity to control the work(of motor
Rate, does not affect the rotation number of motor, can keep stable load torsion.
Loaded equipment in the past is to become motor power using electromagnetic valve, sets load torsion
Construction, but this equipment be measure axle load capacity, control torsion, so motor can be improved
The correctness of characteristic check.
With reference to shown in Fig. 6, measure the torsion of axle, control the rotation number of motor to be gradually reduced,
During no load condition, motor maximum speed to be rotating, thus control the power supply of motor to control under
Reduction of speed degree.
Staking punch part contacts by pressure object with regard to load capacity greatly, can drop motor rotary speed,
Set punching press torsion under this state, using controlling the big power supply of horse, turned round using the punching press setting
Power is pressed object to be pressed into.
Follow if being compared with previous mode, press-in panel does not have load cell, so must not
The intensity of load cell to be considered, structure is simple, can make the stamping machine of low cost.
With reference to shown in Fig. 7, using electromotor or motor vehicle actual travel experimentally,
Improve engine support to detect the load capacity of engine support, when also can detect that vehicle travels
Torsion.
The foregoing is only the preferred embodiments of the present invention, be not limited to this
Bright, for a person skilled in the art, the present invention can have various modifications and variations.
All any modification, equivalent substitution and improvement within the spirit and principles in the present invention, made
Deng should be included within the scope of the present invention.
