The utility model discloses a sampling of safety light curtain prevents that people's hand, head from dividing the entering dangerous part, if get into, signal of receiver output, after host computer CPU the control unit was given in the processing, host computer CPU the control unit sent command control electro -discharge machine tools, and the time -out discharges or closes the lathe. The utility model discloses the basis that is not influencing accurate electro -discharge machine tools down, can effectual guardian and equipment safety, the emergence of reduction accident.
Description
Technical field
This utility model is related to provide electrical discharge machine field, is not more particularly to affecting accurate discharging processing machine
Under the basis of bed, there is provided a kind of accurate electric discharge machine tool safety protection device, people and equipment safety is effectively protected, accident is reduced
Occur.
Background technology
Safety in production is referred in enterprise business, in order to avoid causing the accident of personnel's injury and property loss
And corresponding accident prevention and control measure are taken, production process is carried out under conditions of regulation is met, to ensure the people that obtains employment
The personal safety of member and health.
Electrical discharge machine is made up of plus lathe processing power source control device, and electro-discharge machining is by high-low pressure pulse group
The processing pulse of synthesis, temporally division is generally divided into pulsewidth (ON) and arteries and veins stops (OFF) two stages, wherein, applies during processing
The stage of high pressure is named the ON stages, and the stage for applying low pressure or shut-off is named the OFF stages.In the ON stages, when the electric field intensity foot in gap
When enough big, then there is electric discharge in the insulation characterisitic destruction of the dielectric fluid between gap, and the High Temperature High Pressure for producing of discharging makes workpiece material
Evaporation melts to reach the purpose for removing workpiece material.This process can produce high voltage and high current high temperature, if operator is not
Note, it may occur that electric shock, burn hazard, cause personal safety accident.
Utility model content
For the problems of the prior art, the purpose of this utility model is to provide a kind of accurate electric discharge machine tool safety protection
Device, to be effectively protected people and equipment safety, reduces the generation of accident.
To achieve these goals, the technical solution of the utility model is as follows：
Accurate electric discharge machine tool safety protection device, it is characterised in that including safe light curtain unit, signal conversion unit, letter
Number interface unit, host computer CPU control units；
The safe light curtain unit includes emitter and the receptor being oppositely arranged, and is provided with multiple infrared inside emitter
Transmitting tube, installs the infrared receiving tube of corresponding equal number equally arrangement inside receptor；Each infrared transmitting tube and red
Outer reception pipe is all arranged on same straight line, just forms infrared ray light curtain between emitter and receptor；
The safe light curtain unit, signal conversion unit, signal interface unit, host computer CPU control units are sequentially connected,
Host computer CPU control units are connected with the shift servo control unit of accurate electric discharge lathe.
In preferred embodiment of the present utility model, also include the display control unit to display alarm signal, show
Control unit is connected with host computer CPU control units.
The receptor of safe light curtain unit is according to whether blocking infrared ray, output unlike signal, through a series of conversions, turn
Change the signal that host computer CPU control units can be received.Host computer CPU control units send different instruction according to unlike signal, control
Lathe processed suspends or shuts down.Simultaneously in display device display alarm signal.
When having barrier by so as to block infrared ray, infrared receiving tube will receive modulated signal, and internally circuit is defeated
Go out high level, conversely, internal circuit can export low level.
It is exactly to protect personal safety to escape injury that the effect of safe light curtain unit is said directly to put, and personal safety here
Finger, palm and arm is primarily referred to as, because we are when machine runs, major part is to allow handss to be in deathtrap.
This utility model is sampled using safe light curtain, prevents the handss of people, head to be partially into dangerous part, if entered,
Receptor exports a signal, and after processing and giving host computer CPU control units, host computer CPU control units send instruction
Control electrical discharge machine, temporarily electric discharge or closing lathe.This utility model is not affecting the basis of accurate electrical discharge machine
Under, people and equipment safety can be effectively protected, the generation of accident is reduced.
The characteristics of this utility model, see the detailed description of this case schema and following preferable embodiment and obtain clear
Ground understands.
Description of the drawings
Fig. 1 is control principle block diagram of the present utility model.

Safe light curtain unit 10 includes the emitter 11 being oppositely arranged and receptor 12, is provided with multiple red inside emitter
Emission pipe, installs the infrared receiving tube of corresponding equal number equally arrangement inside receptor；Each infrared transmitting tube and
Infrared receiving tube is all arranged on same straight line, just forms infrared ray light curtain between emitter and receptor；
Safe light curtain unit 10, signal conversion unit 20, signal interface unit 30, host computer CPU control units 40 are successively
Connection, host computer CPU control units 40 are connected with the shift servo control unit 60 of accurate electric discharge lathe.
Display control unit 50 is connected with host computer CPU control units 40.
The receptor 11 of safe light curtain unit according to whether blocking infrared ray, exports unlike signal, through a series of conversions,
The signal that conversion host computer CPU control units 40 can be received.Host computer CPU control units 40 send difference according to unlike signal
Instruction, control lathe suspend or shut down.Simultaneously in display device display alarm signal.
When having barrier by so as to block infrared ray, infrared receiving tube will receive modulated signal, and internally circuit is defeated
Go out high level, conversely, internal circuit can export low level.
Ultimate principle of the present utility model, principal character and advantage of the present utility model has been shown and described above.One's own profession
