Description

The safe clamping device control system of a kind of numerically controlled lathe

Technical field

The utility model belongs to numerically controlled lathe control field, based on relating to oneplant the safe clamping device control system of numerically controlled lathe.

Background technology

Manually in the time of the clamping device of operation lathe, after operator is arranged on product on clamping device, after clamping, the baffle plate of clamping device can automatically be pushed down product within the time of setting, if operator is in the time being on night shift, and distraction, after product is delivered on lathe and to be clamped, hand is not also taken away in time, and baffle plate is come with regard to automatic pressing, very easily causes serious industrial accident.

Utility model content

The utility model is the security hidden trouble existing while overcoming manual operation numerically controlled lathe clamping device, proposes oneplant the safe clamping device control system of numerically controlled lathe.

The technical scheme that the utility model adopts is as follows:

oneplant the safe clamping device control system of numerically controlled lathe, the main shaft of described numerically controlled lathe is driven by motor relay; The chuck of described numerically controlled lathe and baffle plate are driven by corresponding hydraulic system, and the valve event of described hydraulic system is by corresponding auxiliary reclay control, and described motor relay and auxiliary reclay access lower arrange control circuit:

The positive wire 1 of described control circuit is connected to normally opened contact, the normally closed contact of auxiliary reclay KA2, the auxiliary reclay KA of emergency stop switch S, auxiliary reclay KA successively, and described auxiliary reclay KA directly controls the valve of a hydraulic system;

The auxiliary reclay KA2 valve of also directly controlling a hydraulic system in parallel with auxiliary reclay KA, is in series with the normally closed contact of auxiliary reclay KA1, the normally opened contact of auxiliary reclay KA1 successively between the normally opened contact of described auxiliary reclay KA and auxiliary reclay KA2;

Auxiliary reclay KA3 is in parallel with auxiliary reclay KA, is connected with the normally opened contact of KA3 between the normally opened contact of described auxiliary reclay KA and auxiliary reclay KA3 in turn, and the normally opened contact of KA3 is in parallel with the normally closed contact of KA1;

Auxiliary reclay KA1 and auxiliary reclay KA are also in parallel, between the normally opened contact of described auxiliary reclay KA and auxiliary reclay KA1, be in series with successively normally closed contact, the normally open push button switch SB1 of KA1, between described emergency stop switch S and normally open push button switch SB1, be connected with the normally closed contact of motor relay;

Between the positive wire 2 of described control circuit and auxiliary reclay KA4, be in series with successively the normally opened contact of normally open push button switch SB1, auxiliary reclay KA;

Between the positive wire 2 of described control circuit and motor relay M3, be in series with successively normally opened contact, the normally closed push button switch SB3 of KA4; Motor relay M3 is also connected with the normally opened contact of KA;

The normally closed contact of series electric motor relay normally open contact, KA2 successively between the positive wire 2 of described control circuit and auxiliary reclay KA5; The normally opened contact parallel connection of motor relay normally opened contact and KA5.

Its principle of work is:

1, in the time that button normally opened contact switch S B1 is closed, the coil of auxiliary reclay KA1 obtains electric, and the corresponding normally opened contact of auxiliary reclay KA1 becomes normally closed, auxiliary reclay KA coil obtains electric, the normally opened contact of auxiliary reclay KA becomes normally closed self-locking, and now, chuck is clamped condition.

In the time that button normally opened contact switch S B1 unclamps, auxiliary reclay KA3 coil obtains electric, and the corresponding normally opened contact switch of auxiliary reclay KA3 becomes normally closed, auxiliary reclay KA3 self-locking;

2, in the time that button normally opened contact switch S B2 presses, auxiliary reclay KA4 coil obtains electric, the corresponding normally opened contact of auxiliary reclay KA4 becomes normally closed self-locking, motor relay M3 coil obtains electric simultaneously, the corresponding normally opened contact of motor relay M3 becomes normally closed contact simultaneously, and main shaft starts, and auxiliary reclay KA5 coil obtains electric, baffle plate starts to clamp, and KA5 often opens and becomes normally closed self-locking simultaneously;

3, after main shaft starts, while pressing the button normally opened contact switch S B1, now do not have any action, chuck and baffle plate all keep former action, and chuck can not unclamp, and baffle plate also can not unclamp;

4, in the time pressing the button normally closed contact switch S B3, motor relay M3 coil blackout, main shaft stops, at this moment press the button after normally closed contact switch S B1, auxiliary reclay KA1 coil blackout, the corresponding normally opened contact switch of auxiliary reclay KA1 becomes normally closed, auxiliary reclay KA2 coil obtains electric, the corresponding normally closed contact of auxiliary reclay KA2 becomes often to be left, and auxiliary reclay KA dead electricity disconnects, and removes self-locking, auxiliary reclay KA3 is also dead electricity disconnection simultaneously, remove self-locking, auxiliary reclay KA5 coil losing electricity disconnects, and meanwhile chuck and baffle plate just unclamp simultaneously.

Advantage of the present utility model is:

The utility model reaches the controllability of baffle plate, chuck and main shaft action by pushbutton switch by control circuit, when operator is after clamping product, can be chosen in handle takes away, close behind the door, just press after lower main axis start button, at this moment baffle plate is just come, by after start working, the generation of the industrial accident that while having avoided hand also not take away in time, baffle plate comes to cause with regard to automatic pressing, produces guarantee is provided for factory is normal.
