Abstract
The utility model belongs to the field of numerical control machine tools, and particularly relates to a motor emergency stopping control circuit of a numerical control machine tool. The control circuit includes a relay arranged on the circuit to control the rotation of a motor shaft, and further includes a manual emergency stopping button serially connected with the relay. The manual emergency stopping button is controlled by the key for controlling a main emergency stopping button of the numerical control machine tool. Moreover, the control circuit also includes an AC contactor serially connected with the relay and the manual emergency stopping button, and connected with the main power supply circuit of the numerical control machine tool. The circuit provided can effectively prevent a spindle box form coming off when the numerical control machine tool manually stops in emergency or suddenly powers off (especially, a numerical control machine tool without a counterweight) and protects a workpiece or a cutter head, thereby improving the performance and the safety of the numerical control machine tool and reducing the maintenance rate.
Description
Technical field
The utility model belongs to the Digit Control Machine Tool field, is specifically related to a kind of electric machine of numerically controlled machine emergent stopping control circuit.
Background technology
Existing Digit Control Machine Tool is the speed that the raising main spindle box moves up and down, and generally takes to remove the mode of counterweight.For controlling its motor shaft of motor that main spindle box moves up and down, mainly by an independent circuit for controlling motor, controlled, be provided with a relay on this circuit, when Digit Control Machine Tool is not worked, relay remains open state, control circuit disconnects, and motor shaft is in being that locking can not be rotated (being band-type brake) by braking state, and after the Digit Control Machine Tool energising, relay obtains the instruction closed relay again, control circuit is communicated with, and motor shaft is rotatable.In the situation that there is no counterweight, when lathe emergent stopping or outside power machine suddenly, relay on circuit for controlling motor disconnects needs certain hour, cause motor locking immediately to shut down, thereby make the main spindle box moved up and down by Electric Machine Control fully fall 0.4 millimeter under the moment of outage, in case of emergency may interrupt cutter head or defective work piece.
The utility model content
The purpose of this utility model is to provide a kind of electric machine of numerically controlled machine emergent stopping control circuit fallen under main spindle box that prevents for addressing the above problem.
Above-mentioned technical purpose of the present utility model is achieved by the following technical programs:
A kind of electric machine of numerically controlled machine emergent stopping control circuit, comprise the relay road of rotating for controlling motor shaft be arranged on circuit, also comprise the manual emergency stop button of connecting with relay, described manual emergency stop button is by the key control of pressing of controlling the total emergency stop push button of Digit Control Machine Tool.
The manual emergency stop button is set on circuit for controlling motor to be used for the hand off circuit for controlling motor motor shaft locking can not be rotated, and the manual emergency stop button is that a button can touch two buttons simultaneously by what control the total emergency stop push button of Digit Control Machine Tool by key control, also locking immediately of motor shaft while guaranteeing that manual emergency stops Digit Control Machine Tool, thus to such an extent as to can effectively prevent that circuit for controlling motor from receiving instruction by relay and disconnecting main spindle box again and descend after the certain hour of interval within this short time.
As preferably, also comprise the A.C. contactor of with relay, manual emergency stop button, connecting and being connected with total power supply circuits of Digit Control Machine Tool.
Can cut off circuit for controlling motor by the manual emergency stop button when touching the button of total emergency stop push button simultaneously, but in the situation that outage suddenly, the manual emergency stop button can't be realized this function, after way circuit cuts off, the interior relay of certain hour just can respond and cut off circuit for controlling motor, the function of falling under can't realizing preventing.The present invention increases an A.C. contactor be connected with total power supply circuits on circuit for controlling motor again, makes when total power supply circuits disconnect suddenly, and A.C. contactor also reacts and disconnect circuit for controlling motor at once, prevents from falling under main spindle box.
In sum, the utlity model has following beneficial effect:
1, this circuit is in the situation that the Digit Control Machine Tool manual emergency stops or outage (Digit Control Machine Tool that particularly there is no counterweight) suddenly can prevent from falling under main spindle box effectively; protection workpiece or cutter head are not damaged; improve performance and the fail safe of Digit Control Machine Tool, reduced maintenance rate.
2, this circuit structure is simple, and controllability is high, practical, and cost is low.
the accompanying drawing explanation
Fig. 1 is the circuit for controlling motor structural representation;
Fig. 2 is the total power supply circuits of Digit Control Machine Tool;
1-relay in figure, 2-manual emergency stop button, 3-A.C. contactor.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
This specific embodiment is only to explanation of the present utility model; it is not to restriction of the present utility model; those skilled in the art can make to the present embodiment the modification that there is no creative contribution as required after reading this specification, but as long as all are subject to the protection of Patent Law in claim scope of the present utility model.
Embodiment:
As shown in drawings, a kind of electric machine of numerically controlled machine emergent stopping control circuit, comprise the relay road 1 of rotating for controlling motor shaft be arranged on circuit, also comprise the manual emergency stop button 2 of connecting with relay 1, described manual emergency stop button 2 is by the key control of pressing of controlling the total emergency stop push button of Digit Control Machine Tool.Also comprise the A.C. contactor 3 of with relay 1, manual emergency stop button 2, connecting and being connected with total power supply circuits of Digit Control Machine Tool.
This circuit, in the situation that the Digit Control Machine Tool manual emergency stops or outage (Digit Control Machine Tool that particularly there is no counterweight) suddenly can prevent from falling under main spindle box effectively, is protected workpiece or cutter head, and the performance and the fail safe that have improved Digit Control Machine Tool, reduced maintenance rate.
