Abstract
The invention discloses a backup source for a numerically-controlled machine tool. The backup source comprises a backup battery, a rectifier connected with the backup battery, and a thermal changer connected with the rectifier. The numerically-controlled machine tool is connected with the thermal changer. The backup battery is connected with a charging circuit. The charging circuit is connected with an external power source. Under the buffering action of the thermal changer, the starting current is small, and therefore the tripping at the time of starting, and the burnout of a circuit and machine tool equipment can be prevented.
Description
Technical field
The present invention relates to a kind of Digit Control Machine Tool back-up source.
Background technology
The digital control system of Digit Control Machine Tool is responsible for service data, and setting data and procedure, and its data are generally stored in RAM memory, and after system cut-off, by back-up source, interim power supply guarantees that data do not lose.In addition, Digit Control Machine Tool is normally used is three-phase alternating current 380V power supply, and the unstable power-supply system that may damage Digit Control Machine Tool of power supply, causes Digit Control Machine Tool to work.Therefore, Digit Control Machine Tool is all equipped with back-up source, at during accidental power failure or electrical network, provides interim power supply when abnormal, makes Digit Control Machine Tool complete uncompleted operation.The Digit Control Machine Tool back-up source of prior art adopts the large electric capacity of 10000uF/400V.Immediate current while adopting the Digit Control Machine Tool of this technology to start is very large, reaches 50A, larger to the impact of place electrical network, corresponding fragile Digit Control Machine Tool.If have a few number of units controlled machines to start in an electrical network, very easily cause and tripping operation burn out circuit simultaneously.And the back-up source of prior art, just charging when Digit Control Machine Tool starts, has further strengthened the network load that starts moment.
Summary of the invention
The object of the invention is to overcome the defect existing in prior art, provide a kind of starting current little, first start afterwards and charge, start the shock-free Digit Control Machine Tool back-up source of balance.
For achieving the above object, technical scheme of the present invention has been to provide a kind of Digit Control Machine Tool back-up source, comprise backup battery, the rectifier being connected with described backup battery, the thermal change device being connected with described rectifier, described Digit Control Machine Tool is connected with described thermal change device, described backup battery is connected with charging circuit, and described charging circuit is connected with external power source.
As preferably, the alternating current that described external power source is 110V-260V.
As preferably, between described thermal change device and described Digit Control Machine Tool, be provided with adjustable resistance.
As preferably, the direct current of described transformer output 380V-420V.
Advantage of the present invention and beneficial effect are: by the cushioning effect of thermal change device, starting current is little, trip, burn out circuit and machine tool in the time of can preventing from starting.
Accompanying drawing explanation
Fig. 1 is schematic diagram of the present invention.
Embodiment
Below in conjunction with drawings and Examples, the specific embodiment of the present invention is further described.Following examples are only for technical scheme of the present invention is more clearly described, and can not limit the scope of the invention with this.
As shown in Figure 1, a kind of Digit Control Machine Tool back-up source, comprise backup battery, the rectifier being connected with described backup battery, the thermal change device being connected with described rectifier, described Digit Control Machine Tool is connected with described thermal change device, described backup battery is connected with charging circuit, described charging circuit is connected with external power source, described external power source is the alternating current of 110V-260V, between described thermal change device and described Digit Control Machine Tool, be provided with adjustable resistance, the direct current of described transformer output 380V-420V.
The above is only the preferred embodiment of the present invention; it should be pointed out that for those skilled in the art, do not departing under the prerequisite of the technology of the present invention principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
