A circulating water-cooled CNC machine tool

Abstract

The utility model discloses a circulating water-cooled numerical control machine tool, comprising a numerical control machine tool body. When a user uses the numerical control machine tool to process parts, the user starts a second hydraulic pump to spray water in a water tank onto the parts through a nozzle to cool the processed parts, and waste residues on the surfaces of the processed parts are washed away by the water. As the water flows from the gap at the bottom of the numerical control machine tool body to a collection box, the water with the waste residues passes through a first filter screen for a first round of filtration, effectively separating large particles of waste residues from the water, and then passes through a second filter screen for a second round of filtration, and finally passes through an activated carbon layer. Finally, the filtered clean water is stored in the collection box, and the first hydraulic pump is started to recirculate water from the first water pipe and the second water pipe to the water tank. When there is too much waste residue on the first filter screen and the second filter screen, the first filter screen and the second filter screen are taken out by holding a third handle to clean the waste residues thereon.

[0002] CNC machine tool is the abbreviation of digital control machine tool, which is an automatic machine tool equipped with a program control system. The control system can logically process programs specified by control codes or other symbolic instructions, decode them, and express them in coded numbers. They are input into the CNC device through information carriers, and various control signals are sent by the CNC device after calculation and processing to control the action of the machine tool, and automatically process parts according to the shape and size required by the drawing. CNC machine tools have better solved the problem of complex, precise, small batch and multi-variety parts processing. They are flexible and high-efficiency automatic machine tools, representing the development direction of modern machine tool control technology, and are a typical mechatronics product.

[0003] The existing filtering device of partially circulating water-cooled CNC machine tools is not convenient for disassembling the filter to clean the waste residue, which may cause the filter to be blocked by the waste residue, so that the cooling water cannot be well recycled, resulting in a waste of water resources. At the same time, the filtering device of partially circulating water-cooled CNC machine tools only has one filter, which may cause the waste residue to be not filtered cleanly enough and the water contains too many impurities, causing damage to the hydraulic pump. Utility Model Content

At the same time, the filtering device of the partially circulating water-cooled CNC machine tools is only provided with one filter, which may cause the waste residue to be not filtered cleanly enough and the water contains too many impurities, causing damage to the hydraulic pump.

[0013] 1. The utility model provides a first filter screen and a second filter screen, and the first filter screen and the second filter screen are both slidably connected to a collection box. The sliding structure effectively facilitates users to disassemble the first filter screen and the second filter screen. When the user starts the second hydraulic pump, the water in the water tank is sprayed onto the parts through the nozzle to cool the processed parts. The waste residue of the processed parts will flow into the collection box from the gap at the bottom of the CNC machine tool body along with the water. The water with the waste residue will pass through the first filter screen for a first round of filtration to separate large particles of waste residue from the water. The water will pass through the second filter screen for a second round of filtration to separate smaller waste residue from the water. When there is too much waste residue on the first filter screen and the second filter screen, the user can hold the third handle to take out the first filter screen and the second filter screen to clean the waste residue on them.

[0014] 2. The utility model sets an activated carbon layer, and a collection box is slidably connected on one side. After the water containing waste residue is filtered twice, it passes through the activated carbon layer again, effectively separating other fine impurities in the water, making the water cleaner and preventing the water from containing too many impurities and causing damage to the hydraulic pump;

[0015] 3. The utility model provides a glass plate, one side of which is fixedly connected to a water tank, which effectively facilitates users to observe the water conditions inside the water tank at the top.
