Specific embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clear, complete
Site preparation is described, it is clear that described embodiment is only a part of embodiment of the invention, rather than whole embodiments.It is based on
Embodiment in the present invention, it is every other that those of ordinary skill in the art are obtained under the premise of creative work is not made
Embodiment, belongs to the scope of protection of the invention.
As shown in Fig. 2 the present invention proposes a kind of anti-signal false touch circuit for hydraulic lathe, hydraulic lathe includes machine
Bed lathe bed and planker, bed piece are provided with common wire, and planker is provided with the contact linked with holding wire, contact and machine tool
Body insulate, and common wire and holding wire connect voltage-contrast circuit and signal output apparatus respectively, when planker moves to bed piece
The end when, contact and common wire are turned on, voltage-contrast circuit output low level, signal output apparatus output signal.
The present invention allows contact to be not turned in the case of non-direct contact by increasing contrast potential circuit, solves existing
Contact water drenching causes the problem of malfunctioning machine in having technology.
Signal output apparatus include optocoupler, diode and first resistor, the first pin connection 12V voltages of optocoupler, optocoupler
Second pin connected with diode and first resistor, the 3rd pin of optocoupler ground connection, the 4th pin connects output line.
Voltage-contrast circuit includes second resistance, 3rd resistor, the 4th resistance, the 5th resistance, the 6th resistance, the 7th resistance
And voltage comparator, the two ends of second resistance are connected with the output end and the first leads ends of voltage comparator respectively, voltage ratio compared with
The output end of device is connected with signal output apparatus, and second resistance is connected with 12V with the common port of the first pin of voltage comparator
Voltage, the also common port with 3rd resistor and the 5th resistance are connected, and the other end of the 5th resistance connects voltage comparator respectively
One end of second pin and the 6th resistance, the other end connection common wire of the 6th resistance, the 4th pin of voltage comparator connects
Common wire is connect, the other end of 3rd resistor connects one end of the 4th resistance and one end of the 7th resistance respectively, the 4th resistance
The other end connects common wire, and the other end of the 7th resistance is provided with common port with the 3rd pin of voltage comparator, and the common port leads to
Cross switch connection contact.As shown in Fig. 2 resistance R2 is pull-up resistor, it is ensured that the port 0 of voltage comparator is in planker without in place
Shi Douwei high level.The voltage of the port-in1 of resistance R5 and resistance R6 regulation voltage comparators is 2.6V.Resistance R3 and resistance
The voltage of R4 regulation resistance R7 one end is 10V, because this chip can only support the voltage of maximum 10V, increases R7 electricity
