止し得るよう構成した電気加工装置に関する。[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to electrical processing equipment, and in particular, when machining fluid is used for machining, leakage or overflow of the machining fluid can be detected at an early stage to prevent unexpected disasters, etc. The present invention relates to an electrical processing device configured to prevent such problems from occurring.

In recent years, various electric machining devices such as electrical discharge machining devices and electrolytic machining devices have become widespread, and with the development of automatic control equipment, it has become possible to operate these electric machining devices unattended for long periods of time.

なうようになつている。 In the above-mentioned electric machining equipment, machining is generally performed by placing the workpiece and the tool electrode facing each other and applying a voltage such as a voltage pulse between the two. When performing the machining, the machining part is immersed in a machining fluid filled in a machining tank, or the machining fluid is constantly supplied to the machining part.
上記加工液としては、放電加工装置の場合には

各種電解液が用いられる。 As the machining fluid, kerosene, pure water, water with some chemical substances added, etc. are used in the case of electric discharge machining equipment, and various electrolytes are used in the case of electrolytic machining equipment.

れ出るのを未然に防止し得るようになつている。 The above-mentioned machining fluid becomes contaminated during processing, and its concentration and temperature must also be maintained at appropriate levels. Therefore, the machining fluid in the machining tank should be collected and purified as appropriate. In some cases, the liquid may be adjusted in concentration and other liquid properties before being fed into the processing tank again. For this reason, a float switch or other liquid level detector is installed inside the processing tank to control the amount of liquid in the tank to always be kept at a constant level, and the tank itself is also equipped with an overflow pipe to prevent excessive The supplied machining fluid is naturally drained from the tank, thereby preventing the machining fluid from overflowing from the machining tank.

装置のみでは必ずしも充分ではなかつた。 However, when the machining tank is moved by numerical control during positioning or machining, the machining fluid in the machining tank may ripple and spill out of the machining tank, and the float switch may malfunction. In some cases, the seal on the processing tank is not perfect and the processing fluid leaks out in small quantities.In such cases, if the processing fluid is flammable such as kerosene, there is a risk of fire. Furthermore, if water or electrolyte is present, it is unacceptable that it will cause corrosion of various parts of the machine, and it will be difficult to continue normal machining.To prevent these unexpected accidents, conventional Float switches and other safety devices alone were not always sufficient.

る。 The electric discharge machine main body 1 itself is a known electric discharge machine, in which a workpiece 10 and an electrode 9 are opposed to each other with a predetermined machining gap maintained in a machining tank 6 filled with machining fluid 11, and machining is performed between them. By applying a voltage pulse from the power supply device 12 for the processing, an electric discharge is generated within the machining gap, and the discharge erosion etch a machining shape corresponding to the shape of the electrode 9 on the workpiece. During the period, the machining fluid 11 is supplied from the service tank 13 through the pump 14 and the solenoid valve 15 into the machining tank 6, and the machining fluid contaminated with machining debris or altered by electric discharge is supplied to the service tank via a filter 16, etc. 13, and the machining fluid adjusting device 17 performs concentration adjustment and other liquid quality control, so that the machining fluid in the machining tank 6 always maintains a constant liquid quality. In addition, new machining fluid is constantly supplied to the minute machining gap formed when the electrode 9 and the workpiece 10 face each other through a machining fluid jet nozzle (not shown in the figure) or a machining fluid jet hole formed in the electrode 9 itself. The machining fluid is jetted out, the machining fluid contaminated with machining debris, etc. is removed from the machining gap, and it is constantly replaced with clean machining fluid. As shown, a liquid level detector, a liquid temperature detector, etc. (not shown in the figure) are provided, and their output data is led to the machining fluid control device 18, so that the supply of machining fluid, etc. is controlled based on this. It's getting old.

あり得ないことではない。 Therefore, accidents such as overflow of machining fluid from the machining tank 6 due to oversupply of machining fluid, etc., can be prevented to some extent by a liquid level detector, an overflow pipe, etc. in the machining tank. However, one side of the machining tank 6 usually has a door that can be opened and closed in order to facilitate the installation and removal of workpieces, and water leakage caused by poor sealing should be avoided by contacting the liquid level detector or overflow pipe, etc. Furthermore, although it is extremely rare in terms of probability, there are cases where the liquid level detector or machining liquid control device 18 fails or the overflow pipe stops functioning. The amount of machining fluid supplied needs to be changed depending on the machining shape and other machining conditions, and it is not impossible for machining fluid to overflow from the machining tank due to programming errors. .

It is configured to send a signal to the machine, machining fluid control device 18, etc. to stop machining.

A gutter member 26 is attached so as to go around the outer circumference of the machining bed, and the gutter member collects the machining liquid flowing down the outer wall of the machining bed. The machining fluid detection sensor 20 is configured to detect this. If the gutter member 26 is attached to the processing bed so that the outlet 26' is at its lowest point, all the processing fluid flowing down at any position on the outer wall of the processing bed can be quickly collected in the butt 25. As a result, detection time becomes faster and prompt response becomes possible.
