Abstract
The invention relates to a device for adjusting and controlling sealing height of a sliding block of an air compressing machine. A numeric display setting unit adopts a touch screen; a control arithmetic unit adopts a programmable controller and a converter; a transmission unit of the machine adopts a motor and is fixed by a locking nut; and a fixed column of the device is fixed in a notch of an adjusting control seat by assembling a mechanical part driven by a worm gear. Firstly, displacement is set by the touch screen; then the set displacement is sent to the programmable controller and the converter forming the control arithmetic unit to control the transmission unit of the machine to operate; a speed reducer of the transmission unit of the machine drives a encoder to rotate; the rotating encoder outputs pulse signals according to the rotating angle to the programmable controller; and the control arithmetic unit calculates the captured pulses of the encoder, simultaneously transmits the displacement of the transmission unit of the machine to the touch screen, and displays the current displacement on the touch screen.
Description
Technical field
The present invention relates to a kind of control gear, particularly a kind of device for adjusting and controlling sealing height of sliding block of air compressing machine.Belong to the air compressing machine technical field.
Background technique
At present, the method that the air compressing machine closed height is regulated control is: mechanical dead location, and promptly to use the mechanical shutter position limit switch, or position with inductor, another does not have any location, and closed height carries out in regulating by feel.They all exist a lot of shortcomings: positioning error is big, adjust inconvenience etc.Along with the development of production technology, the automaticity of machinery is more and more higher, and is also more and more higher to the requirement of the closed precision of mould, and a kind of novel positioning means is badly in need of in mechanical location and can not meet the needs of production with the mode of inductor location.
Summary of the invention
The object of the present invention is to provide a kind of easy to adjust, Location accuracy is high, automaticity is high a kind of device for adjusting and controlling sealing height of sliding block of air compressing machine.
Solving the technological scheme that its technical problem adopts is: a kind of device for adjusting and controlling sealing height of sliding block of air compressing machine, it is characterized in that it comprises, mechanical transmission unit, described mechanical transmission unit is made up of slide block, turbine, worm screw, motor and the rotating coder that is connected with worm screw; Carry out the setting of displacement amount or angle and the numerical value display setting unit that current displacement amount shows then.
Control and calculation unit is used for carrying out numerical operation and according to the setting displacement amount that transmits from numerical value display setting unit, the operation of machine is controlled.
Rotating coder, it via the worm screw driven rotary, sends certain pulse according to the angle of rotation to control and calculation unit by motor.
Described control and calculation unit is carried out computing to the pulse that captures encoder, convert the displacement amount of machine gear unit to, compare computing with the displacement amount of setting again and simultaneously the displacement amount of machine gear unit is sent to numerical value display setting unit, and on numerical value display setting unit, show current displacement amount.
Control and calculation unit is made following selection to the control of machine gear unit after current displacement amount and setting displacement amount are compared:
(1) when the displacement amount of machine gear unit during less than the displacement amount set, control and calculation unit continues the operation of drive machines gear unit.
(2) when displacement amount that the displacement amount of machine gear unit equals to set, control and calculation unit just makes machine transmission arithmetic element out of service.
Working principle of the present invention is: at first set numerical value (displacement amount) by numerical value display setting unit, then the numerical value of setting is sent to control and calculation unit, the operation of control and calculation unit control machine gear unit, the machine gear unit is by the rotation of coupling rotary driving encoder, rotating coder sends certain pulse according to the angle of rotation, Operations Analysis just carries out computing to the pulse that captures encoder, convert the displacement amount of machine gear unit to, compare computing with the displacement amount of setting again, displacement amount with the machine gear unit is sent to numerical value display setting unit simultaneously, and shows current displacement amount on numerical value display setting unit.When machine gear unit displacement amount during less than the displacement amount set, control and calculation unit continues the operation of drive machines gear unit, when displacement amount that the displacement amount of machine unit equals to set, control and calculation unit just makes machine transmission arithmetic element out of service, the position that the current location of machinery equals to set, thus a position fixing process finished.Total the above, Location accuracy height of the present invention, easy to adjust.When needs were readjusted the location, it was just passable only to need to reset numerical value on the numerical value display setting unit again, and unlike traditional mode that is decided to be in the past: thread, adjust positioning block or position of inductor etc.
Beneficial effect: owing to adopted such scheme, the present invention can effectively solve the defective that positioning error is big, adjust inconvenience.Improved machine operation Location accuracy height, easy to adjust.When needs were readjusted the location, it was just passable only to need to reset numerical value on the numerical value display setting unit again, traditional mode that is decided to be before having solved: thread, adjust defectives such as positioning block or position of inductor.
