Abstract
The embodiment of the invention provides a method for implementing an automatic moment screwdriver. An embedded computer, a pressure sensor and a current sensor are additionally arranged in an electric screwdriver control circuit, through induction of the magnitude of pressure generated when an electric screwdriver operator turns a screw, the requirement of the operator for rotation moment is judged, the maximum limit working current of a spindle motor is detected and adjusted through the current sensor, and therefore the rotation moment of the electric screwdriver is indirectly changed.
Description
Technical field
The embodiment of the present invention relates generally to embedded computer technology application, under embedded computer hardware environment, particularly realized circuit and the method for the automatic Torque Control of electric screw driver by pressure sensor and current sensor.
Background technology
At present, electric screw driver is widely used, and its turning moment of nearly all electric screw driver is all adopt the adjustment of manual mechanical type, and not easily quantitative adjusting.When turning moment is less than normal, screw is twisted not tight, and when turning moment is excessive, screw terminal is easily impaired.When therefore needing to change turning moment in electric screw driver use procedure, must leading adjustment by rule of thumb, make troubles to use operation.
Summary of the invention
In view of this, the embodiment of the present invention proposes a kind of under embedded computer hardware environment, realized the automatic Torque Control of electric screw driver by pressure sensor and current sensor circuit and method.By to the induction of electric screw driver operator to pressure size during the turn of the screw, judge the demand of operator to turning moment size, and pass through the maximum restriction operating current of current sensor Detection and adjustment spindle motor, thus indirectly realize changing electric screw driver turning moment.
The embodiment of the present invention solves the technical scheme that its technical problem adopts:
On the rotary main shaft of electric screw driver, installation shaft is to pressure sensor, and in spindle motor drive circuitry loop, current sensor is installed, it is made under the management of embedded computer, to measure electric screw driver operator in real time to screw institute applied pressure value, and take this as a foundation in conjunction with the current sensor reading in spindle motor drive circuitry loop, control and the maximum restriction current value changing electric screw driver spindle motor drive circuitry loop.Owing to having fixing functional relation between motor working current and motor output torque, therefore can indirectly realize controlling and changing electric screw driver turning moment.Thus the turning moment realizing electric screw driver is applied to the size of pressure on screw with operator and automatically changes.
The beneficial effect of the embodiment of the present invention is, the automatic Torque Control of electric screw driver is realized by utilizing pressure sensor and current sensor under embedded computer hardware environment, make the easier and hommization of the operation of electric screw driver, thus improve its class and the market competitiveness.
Accompanying drawing explanation
In order to more enter clearly to illustrate the technical scheme of the embodiment of the present invention, briefly introduce to the accompanying drawing used required in description in embodiment below.
Fig. 1 shows the hardware principle block diagram of the embodiment of the present invention.
Fig. 2 shows the manner of execution schematic flow sheet of the embodiment of the present invention.
Detailed description of the invention
In fig. 2, the mode flow process of the automatic Torque Control of electric screw driver starts [step 100], embedded computer finishing equipment after device power of electric screw driver initializes [step 110], then the state of action button is judged, enter circulation [step 130] to be operated, when detecting that action button is pressed, embedded computer judges operation direction of rotation by circuits and sets the polarity [step 140] of electric screw driver feeding electric motors, then the operating pressure value [step 150] that provides to pressure sensor of detection axis, and calculate motor working current limit [step 160] according to the functional relation between motor working current and motor output torque.And then connect electric screw driver feeding electric motors power supply, drive motors rotates [step 170].Enter operation cycle, in this circulation, judge whether stall stops (screw is tightened into position) [step 180] or action button released (people is shut-down operation) [step 190] to motor.
Above-mentionedly be illustrated as preferred embodiment of the present invention, not in order to limit the present invention, all in the spirit and principles in the present invention, any amendment, replacement, improvement etc. done, all should be included within protection scope of the present invention.
