The specific embodiment
As shown in Figure 3, the utility model comprises work tank 1, switch 2, drainage mechanism 3 and control module 4.Work tank 1 is connected setting with the workbench sealing, and workpiece 5 is set on workbench, and workpiece 5 tops are heads 6 of wire cutting machine tool.
The work tank 1 of place work piece 5 is connected with water injecting pump 11 by pipeline, water injecting pump 11 water filling in work tank 1 under control module 4 controls.Also be provided with discharge outlet 12 on the work tank 1, this discharge outlet 12 can be discharged water in the work tank 1.
The utility model is provided with switch 2 on head 6, switch 2 height random 6 (being thickness of workpiece) change, and can adjust liquid level automatically; Switch 2 can produce switching information, and send to control module 4 by floating on liquid level in addition, and control module 4 is controlled water injecting pump 11 and drainage mechanism 3 actions again, thereby realizes the automation of draining and water filling.
As shown in Figure 4, in the utility model, drainage mechanism 3 comprises water fender 31, motor 32 and limit switch 33.Wherein:
In the utility model, work tank 1 also is connected with small pump 13 by pipeline, small pump 13 moisturizing in work tank 1 under control module 4 controls, and small pump 13 flows are less than water injecting pump 11.Small pump 13 is worked when discharge outlet 12 is opened, and can slow down liquid level decrease speed in the work tank 1.
In the utility model, also be provided with second switch, 7, the second switches 7 on the head 6 and be positioned at switch 2 tops, second switch, 7 communication link control modules 4.Second switch 7 is all identical with switch 2 principles and structure.
The utility model also is provided with second switch 7, avoids owing to switch 2 faults cause system's control malfunctioning, and for normal operation of the present utility model provides dual fail-safe, security improves greatly.
In the utility model, discharge outlet 12, water injecting pump 11 and small pump 13 all link to each other with water tank 8 by pipeline.This structure can realize recycling water resource, the conserve water resource.In addition, precipitation structure and cooling structure can be set in water tank 8, make things convenient for water purification and cooling.
During the utility model work, turn off discharge outlet 12 earlier, restart water injecting pump 11 to 1 li water filling of work tank.When rising to switch 2, liquid level can float when coming, switch 2 outputs one signal, and control module 4 was closed and was turned the water injecting pump 11 of 1 li water filling of work tank this moment, opened water fender 31 by motor 32 and gear assembly 34 simultaneously, and opened small pump 13.At this moment liquid level can be owing to opening of discharge outlet 12 descends, and switch 2 just can fall after rise.When falling back to a certain degree, the other signal of switch 2 outputs, control module 4 is turned off work tank 1 discharge outlet 12.This moment, liquid level can raise along with the continuous adding of moisturizing.Be raised to when switch 2 is floated, control module 4 just can be opened work tank 1 discharge outlet 12, and liquid level just can fall after rise.Periodic duty so just can be controlled the height of liquid level, also can make the automatic circulation of 1 li machining medium of work tank (pure water or distilled water).Second switch 7 is protection switches, and when switch 2 was malfunctioning, second switch 7 just can float along with the rising of liquid level; when floating to a certain degree; can export a signal, at this moment control module 4 is turned off water injecting pump 11 and small pump 13, in order to avoid cause damage.
The switch 2 here is fixed on the head 6, and along with the change of workpiece 5 thickness, the position that stops in head 6 process is also changing.So the position of switch 2 also just can change along with the change of workpiece 5 thickness.Thereby can control the height of liquid level in the work tank 1 automatically, reach instructions for use.
The time of wire cutting machine tool processing parts is generally all long, and is round-the-clock often in processing.And need artificial adjust local fewer of operator in the process.If can not realize the unmanned processing of lathe, be a waste greatly to human cost this part undoubtedly.Consider on the one hand that from this utility model has reduced the manual operation in the machining process just, make the automation of lathe and unmanned degree obtain further raising, thereby enhance productivity.Specify as follows:
1. realize the automatic control of liquid level.Reduce operator's work, enhance productivity.Original level control mode is that the part of at every turn processing different-thickness all needs to carry out before the adjustment of liquid level, and it is cumbersome to operate.
2. realize automatic drain function, thereby make machine realize that the degree of unmanned processing is higher, save human cost.The lathe that particularly has the automatic wire feed structure if can't realize the unmanned processing of lathe, just means that also automatic wire feed mechanism does not bring into play due effect.
In sum; it below only is preferred embodiment of the present utility model; be not to be used to limit protection domain of the present utility model; therefore; all any modifications of within spirit of the present utility model and principle, being done, be equal to replacement, improvement etc., all should be included within the protection domain of the present utility model.
