In the electric control system, quick travel motor M3 is controlled by A.C. contactor KMS, according to using needs,
Start and stop can be controlled manually at any time.It is electric that rotating turret handle pressure crawl travel switch SQ obtains contactor KMS, and motor M3 turns
Dynamic, knife rest is realized quick mobile.
The beneficial effects of the invention are as follows：The electric control system is easy to operate, and runnability is stablized, and reliability is high, resists dry
It disturbs that ability is strong, and can easily carry out the setting and modification of various parameters.
Description of the drawings
Fig. 1 is the C650 type horizontal lathe main circuit diagrams of the present invention.
Fig. 2 is the C650 type horizontal lathe electric operation control circuit figures of the present invention.
Specific embodiment
The invention will be further described with reference to the accompanying drawings and examples.
As shown in Figure 1, Figure 2, C650 types horizontal lathe configures 3 motor M1, M2 and M3 altogether.To ensure the normal of main circuit
It runs, the short-circuit protection link using fuse and the motor overload protection ring using electrothermal relay is also provided in main circuit
Section.Main motor Ml completes the driving of main shaft main motion and tool feeding movement, can positive and negative two sides using mode is directly initiated
To rotation, and the electric braking parking of positive and negative two direction of rotation can be carried out.It is easy to adjust to process, also with inching function.
Motor M1 control circuits are divided into 4 parts.
The rotating of motor is made of two groups of main contacts of rotating forward control contactor KM1 and reversion control contactor KM2
Circuit.
Ammeter PA is connected on through current transformer TA on the main circuit of main motor M1, when being worked with monitoring motor winding
Curent change.For ammeter is prevented to be activated rush of current damage, using the break contact KT (P-Q) of the time relay,
By the temporary short circuit of ammeter in the short time of startup.
Series resistance Current limited Control part, the access and excision of the main contacts control current-limiting resistance R of contactor KM3, into
When row crawl adjusts, to prevent continuous starting current from electromotor overload being caused to seal in current-limiting resistance R, to ensure that circuit is set
Standby normal work.
The velocity measuring part of speed relay KS and the main shaft of motor are coaxially connected, during stopping brake, when
When main motor rotating speed is close to zero, moving together contact can cut off the related circuit of reversing braking in control circuit, complete parking
Braking.
When adjusting knife rest, it is desirable that M1 point operation controls.Close disconnecting switch QS, by start button SB2, contactor KM1 obtain it is electric,
MI concatenations current-limiting resistance R slowly runs, and realizes crawl.Unclamp SB2, contactor KM1 dead electricity, M1 stallings.
Disconnecting switch QS is closed, by positive start button SB3, contactor KM3 obtains electric, and intermediate relay KA obtains electric, the time
Relay KT obtains electric, and contactor KM1 obtains electric, and motor M1 short circuit resistance R is positive to be started, in major loop ammeter A by the time after
The break contact short circuit of electric appliance KT, the break contact that the delay of KT disconnects after being delayed t seconds disconnect, and ammeter A is serially connected with main circuit,
Monitor loading condition.In main circuit by current transformer TA access ammeter PA, for prevent start when starting current to electric current
The impact of table, using the break contact of time relay KT by ammeter short circuit during startup, startup terminates, and the break contact of KT breaks
It opens, ammeter comes into operation.Similar when inverting situation about starting with rotating forward, KM3 and KM2 obtains electric, motor reversion.
Assuming that rotate forward, speed relay forward direction break contact KS1 (17-23) is closed M1 before parking.During braking, press
Lower stop button SB1, makes contactor KM3, time relay KT, intermediate relay KA, the equal dead electricity of contactor KM1, in major loop
Seal in resistance R (limitation reversing braking electric current).When SB1 releases, since the contact KS1 (17-23) of speed relay is still closed, make
It obtains KM2 and obtains electric, motor M1 access inverted sequence mains lockings.When speed reduces, and KS1 (17-23) is disconnected so that KM2 dead electricity, system
It is dynamic to terminate.Stopping brake situation when motor M1 is inverted is similar.
Motor M2 provides cutting fluid, is continuous duty, by contactor KM4's using stopping mode being directly initiated
Main contacts controls the connecting and disconnecting of its main circuit.It presses cooling pump start button SB6, contactor KM4 and obtains electric, M2 turns of motor
It is dynamic, coolant is provided.It is powered off by cooling pump stop button SBS, KM4, M2 stops.
Quick travel motor M3 is controlled by A.C. contactor KMS, according to needs are used, can control start and stop manually at any time.
It is electric that rotating turret handle pressure crawl travel switch SQ obtains contactor KMS, and motor M3 is rotated, and knife rest is realized quick mobile.
Since no matter spindle drive motor is rotated forward or inverted in relay-contactor circuit, current-limiting resistance contactor is cut off
KM3 is to act first, in ladder diagram, arranges first branch as excision resistance controlling brancher.Rotating forward and inverting contact
In device controlling brancher, two kinds of self-sustaining, braking control logic relations are combined.It rotates forward in control also added with manual control.
