In the preset time of second time relay.
The utility model has the beneficial effects that the braking of first time relay control milling machine X-axis motor stops, in this base
Second time relay is introduced on plinth, even if operative employee is frequently changed operation direction, second time relay can also change
Constrained delay preset time while direction, the switching operation of operative employee just works after this preset time, to avoid
Operative employee because frequent switching operate direction caused by apparatus failure, reduce maintenance cost, extend the service life of equipment.
Detailed description of the invention
The present invention will be further described with reference to the accompanying drawings and examples:
Fig. 1 is the electronic schematic diagram of the utility model.
Specific embodiment
As shown in Figure 1, the utility model provides a kind of milling machine X-axis brake protection device, including the first A.C. contactor
KM1, the second A.C. contactor KM2, electrothermal relay FR, D.C. contactor KM3, DC injection braking power supply DC, positive switch SQ7, instead
To switch SQ8, first time relay KT1 and the second time relay KT2；First A.C. contactor KM1 is exchanged with second to be connect
The main contacts of tentaculum KM2 is connected by phase negative-phase sequence, and the input terminal of two A.C. contactor main contacts connects three phase mains, output end
It is sequentially connected electrothermal relay FR and milling machine X-axis motor M, the input terminal of D.C. contactor KM3 main contacts connects DC injection braking power supply
DC, output end connect milling machine X-axis motor M；
The normally-closed contact of D.C. contactor KM3, the on-delay normally-closed contact of the second time relay KT2, positive switch
The coil of SQ7, the auxiliary normally-closed contact of the second A.C. contactor KM2 and the first A.C. contactor KM1 are connected to after being sequentially connected in series
Between firewire L1 and zero curve N；The auxiliary normally-closed contact and the second A.C. contactor of reverser SQ8, the first A.C. contactor KM1
The coil of KM2 is connected in parallel on the both ends of forward direction switch SQ7 and the first A.C. contactor KM1 coil after being sequentially connected in series；First exchange connects
The power-off of the auxiliary normally-closed contact, the auxiliary normally-closed contact, first time relay KT1 of the second A.C. contactor KM2 of tentaculum KM1
The coil of delay normally opened contact and D.C. contactor KM3 are connected between firewire L1 and zero curve N after being sequentially connected in series；At the first time after
The coil both ends of electric appliance KT1 and the second time relay KT2 are separately connected firewire L1 and zero curve N；First A.C. contactor KM1 with
The control terminal of first time relay KT1, D.C. contactor are connected after the auxiliary normally opened contact of second A.C. contactor KM2 is in parallel
The auxiliary normally opened contact of KM3 connects the control terminal of the second time relay KT2.
The entrance of firewire L1 is also in series with the normally-closed contact of total control switch SB1 Yu electrothermal relay FR, forward direction switch SQ7 with
Positive X-axis limit switch SQ1, positive Y-axis limit switch are also in series between the auxiliary normally-closed contact of second A.C. contactor KM2
It is also gone here and there between SQ3 and forward direction Z axis limit switch SQ5, reverser SQ8 and the auxiliary normally-closed contact of the first A.C. contactor KM1
It is associated with reversed X-axis limit switch SQ2, reversed Y-axis limit switch SQ4 and reversed Z axis limit switch SQ6.
It powers in use, pressing total control switch SB1 first to control loop, swinging control stick closes forward direction switch SQ7
It closes, the first A.C. contactor KM1 coil is made to obtain electric, main contacts closure, milling machine X-axis motor M forward direction is mobile；When control stick is flapped toward instead
During switch SQ8, forward direction switch SQ7 is disconnected, the first A.C. contactor KM1 coil losing electricity, the first A.C. contactor KM1
Auxiliary normally opened contact disconnect, thus trigger first time relay KT1 work, the power cut off delay of first time relay KT1
It is electric that normally opened contact closure obtains the coil of D.C. contactor KM3, and the main contacts closure of D.C. contactor KM3 makes DC injection braking power supply
DC, which provides braking power, enables milling machine X-axis motor M braking stop, and the preset time of the present embodiment first time relay KT1 is 2s,
At the same time, D.C. contactor KM3 auxiliary normally opened contact closure, thus triggering the second time relay KT2, the second time after
The on-delay normally-closed contact of electric appliance KT2 is opened, thus the power supply of branch where disconnecting forward direction switch SQ7 and reverser SQ8；
At this point, control stick is swung to reverser SQ8, the first A.C. contactor KM2 coil even if operative employee does not press regulation
It will not obtain electric, milling machine X-axis motor M not will start, only after the arrival of the second time relay KT2 preset time, when second
Between the on-delay normally-closed contact of relay KT2 re-close, just again to the operation of forward direction switch SQ7 or reverser SQ8
Effectively, the preset time of second time relay of the present embodiment KT2 is 3s.
By this protective device, so that operative employee is not superficial phenomenon by guidelines, Operation switch does not make electricity
Road really works, and avoids milling machine X-axis motor M frequently forward and reverse starting, and operative employee is avoided to cause because of frequent switching operation direction
Apparatus failure, reduce maintenance cost, extend the service life of equipment.
The above descriptions are merely preferred embodiments of the present invention, not makees in any form to the utility model
Limitation；Anyone skilled in the art, it is all available in the case where not departing from technical solutions of the utility model ambit
The methods and technical content of the disclosure above makes many possible changes and modifications to technical solutions of the utility model, or is revised as
The equivalent embodiment of equivalent variations.Therefore, all contents without departing from technical solutions of the utility model, according to the utility model
