Description

Technical Field

[0001] The utility model relates to the technical field of water level detection, in particular to a water level detection device for a numerically controlled machine tool. Background Art

[0002] CNC machine tools are digitally controlled machine tools, which are automated machine tools equipped with a program control system. The control system can logically process programs specified by control codes or other symbolic instructions, decode them, express them in coded numbers, and input them into the CNC device through information carriers. CNC machine tools sometimes require a lot of water to cool or process products during production and processing, and the water level detection of the water tank in CNC machine tools is crucial.

[0003] After searching, it was found in the Chinese Utility Model Patent Publication No. CN207289629U that a water level detection device for a CNC machine tool was disclosed. Through the air pressure inside the water tank of the CNC machine tool, the change of its internal pressure directly acts on the water level detection device. When it is lower than the lowest water level, the green light of the water level detection device will light up, and when it is higher than the highest water level, the red light will light up. However, the above device can only know the detection data of two water levels, and cannot know the water level in the water tank in real time, which easily makes the water level in the water tank often too low. If this continues for a long time, the machine will be easily damaged. Therefore, a water level detection device that can know the water level in the water tank in real time is needed.

During the water adding process, the floating block will move upward in the track frame as the water level rises. At the same time, the vertical rod will also move upward, and the part extending out of the water tank will gradually increase. Then, the height of the water level in the water tank can be known according to the scale on the water level gauge in the vertical rod, so that the water level can be known before processing to facilitate subsequent processing. After that, after the water in the water tank is gradually used up, the water level in the water tank drops, and the floating block moves downward with the vertical rod. During the downward movement, when the water level is low, the pressure plate on the vertical rod will touch the press switch, causing the alarm to sound an alarm and give a warning, so that the water level in the water tank can be known in real time, so that a clear idea can be obtained before machine tool processing to avoid the situation of temporary water addition during the processing process.

After the water level rises, the floating stop block rises to close the pipe opening, thereby increasing the volume of the water tank in disguised form. BRIEF DESCRIPTION OF THE DRAWINGS
