Description
Technical field
This utility model is related to a kind of safety control, especially relates to a kind of pneumatic door security control device of lathe.
Background technology
The pneumatic door of existing lathe is all not provided with safety control, or is externally provided with safe grating in pneumatic door, by
There is very big inertia in pneumatic door in closing process, still suffer from the danger crushing.
Cn 201953221 u discloses a kind of safe controller for slide door.This controller includes adhesive tape sensor ab, continues
Electrical equipment k2, display lamp d1, d2, power supply ic1, switch k1, resistance r0, r1, r2, r3 are connected to the left end of adhesive tape sensor ab,
Power supply ic2 and photoelectricity misfortune close the right-hand member that circuit ic3 connects adhesive tape sensor ab.Structure and control due to sliding door and pneumatic door
Principle is different, therefore this safety governor is not suitable for the control of lathe pneumatic door.
Utility model content
The technical problems to be solved in the utility model is: overcomes the deficiencies in the prior art, provides a kind of structure simple, operation
Use, the pneumatic door security control device of the high lathe of security performance.
This utility model solves its technical problem and be the technical scheme is that a kind of lathe pneumatic door security control dress
Put, including safe grating, plc(Programmable Logic Controller) controller, left door-closing in-place inductive switch, right door-closing in-place sensing open
Close, open the door electromagnetic valve and electronic valve of closing the door composition；Described safe grating be arranged on pneumatic outdoors, the input of described plc controller
End is electrically connected with safe grating, left door-closing in-place inductive switch and right door-closing in-place inductive switch；The output of described plc controller
End be connected with enabling electromagnetic valve, electronic valve of closing the door, described enabling electromagnetic valve and close the door electronic valve be arranged on plc controller with pneumatic
On the connection line of door drive.
Further, described electromagnetic valve of closing the door is connected with the normally-closed contact of safe grating, described enabling electromagnetic valve and safety light
The normally opened contact of grid connects.
A kind of operation principle of the pneumatic door security control device of lathe of this utility model and using method are: in door closing procedure
In, if safe grating detects obstacle, the normally closed point (x of safe grating0) disconnect, then close the door electromagnetic valve (y1) must not be electric, gas
Dynamic door is failure to actuate, that is, stop closing the door action, meanwhile, the opened point (x of safe grating0) closure, then enabling electromagnetic valve (y0) must be electric,
Pneumatic door carries out door opening action, as shown in Figure 2.
Eliminate when safe grating detects obstacle, the normally closed point (x of safe grating0) close again, opened point (x0) break
Open, close the door electromagnetic valve (y1) again electric, pneumatic door proceeds action of closing the door, as shown in Figure 3.
And work as after pneumatic door secures, the left door-closing in-place inductive switch (sq of pneumatic door1) and right door-closing in-place sensing (sq2)
Switch electric, the normally closed point (x of left door-closing in-place inductive switch10), the normally closed point (x of right door-closing in-place inductive switch11) normally closed point
Disconnect, close the door electromagnetic valve (y1) and enabling electromagnetic valve (y0) all do not reoperate.As shown in Figure 4, left door-closing in-place inductive switch
Opened point (x10), the opened point (x of right door-closing in-place inductive switch11) opened point closure, then lathe carries out next step action, no
Whether pipe safe grating detects obstacle, and plc controller is all no longer controlled to pneumatic door.
A kind of beneficial effect of the pneumatic door security control device of lathe of this utility model: the non-door-closing in-place of pneumatic door it
Before, as long as safe grating detects obstacle, would not carry out closing the door action, and then effectively prevents the wound to operator for the pneumatic door
Evil, improves the security performance of lathe.
