Abstract
The utility model discloses a control system for linear velocity of a grinding machine, which comprises a power supply, a motor and a frequency convertor for controlling the revolving speed of the motor, wherein the frequency convertor is connected with the power supply and the motor. The control system is characterized in that the frequency convertor is connected with a potentionmeter capable of carrying out electrodeless speed regulation by a line and is also provided with a brake resistor which can lead the motor to stop rapidly without causing a high voltage. The action principle of the control system is that the potentionmeter is a given signal source of the frequency convertor, a voltage signal transmitted to the frequency convertor is usually 0-10V, and the voltage of the given signal is adjusted by the potentionmeter so as to control the revolving speed of the motor. Compared with the previous speed regulation system for grinding wheels of the grinding machine, the control system makes substantial progress, can carry out electrodeless speed regulation and is suitable for grinding workpieces with different requirements; besides, the grinding precision is high.
Description
Technical field
The utility model relates to accurate steel band production equipment, and particularly a kind of grinding machine linear velocity is controlled system.
Background technology
Grind the precision height to producing accurate steel band requirement roll; Therefore require emery wheel, workpiece to have different speeds just can reach the different precision that grinds; And the existing grinder wheel and the headstock do not have the stepless time adjustment system at all; The high-precision roller grinder grinding wheel drive mitor of improved has only double speed, does not also have stepless time adjustment, does not therefore reach requirement.
The utility model content
In order to overcome the defective that above-mentioned prior art exists, the utility model provides a kind of grinding machine linear velocity to control system, can carry out stepless time adjustment, is applicable to the workpiece that grinds demands of different, grinds the precision height.
To achieve these goals, the technical scheme of the utility model is following:
A kind of grinding machine linear velocity is controlled system; Comprise the frequency converter of power supply, motor, control motor speed, said frequency converter connects said power supply and motor respectively, is characterized in; Said frequency converter connects the potentiometer that can carry out stepless time adjustment through circuit, also installs braking resistor on the frequency converter additional.
The action principle of the utility model is, said potentiometer is a given signal source of frequency converter, is transferred to voltage signal of said frequency converter, and generally at 0-10V, the adjustment through potentiometer changes given signal voltage.
The given signal voltage of above-mentioned potentiometer is high, and the output frequency of frequency converter is just big, and motor speed is just high.
After the motor normal rotation was got up, when thinking to stop fast, because the effect of inertia of load, quite motor can cause voltage too high in generating, and said braking resistor can just consume the electricity that sends, and can not make equipment cause fault.
The beneficial effect of the utility model is that novel structure had substantial progress than former grinder wheel governing system, can carry out stepless time adjustment, was applicable to the workpiece that grinds demands of different, ground the precision height.
Description of drawings
Fig. 1 is the structural representation of the utility model.
The specific embodiment:
For the creation characteristic, the technological means that make the utility model and reach purpose and be easy to understand and understand, further set forth the utility model below in conjunction with specific embodiment.
Embodiment:
Referring to Fig. 1, a kind of grinding machine linear velocity is controlled system, comprises power supply 2, the frequency converter 1 that is connected with power supply 2, the motor 3 that is connected with frequency converter 1 circuit, the potentiometer 4 that is connected with frequency converter 1, is installed at the braking resistor 5 on the frequency converter 1.
The given signal voltage of said potentiometer 4 is high, and the output frequency of frequency converter 1 is just big, and is just high by motor 3 rotating speeds of its control.
After motor 3 normal rotation were got up, when thinking to stop fast, because the effect of inertia of load, quite motor 3 can cause voltage too high in generating, and said braking resistor 5 can just consume the electricity that sends, and can not make equipment cause fault.
More than show and described the advantage of basic principle, principal character and the utility model of the utility model.The technical staff of the industry should understand; The utility model is not restricted to the described embodiments; The principle of describing in the foregoing description and the specification that the utility model just is described; The utility model also has various changes and modifications under the prerequisite that does not break away from the utility model spirit and scope, and these variations and improvement all fall in the utility model scope that requires protection.The utility model requires protection domain to be defined by appending claims and equivalent thereof.
