Description

Technical Field

[0001] The utility model relates to the technical field of machine tools, in particular to a metal chip recycling and cleaning structure for a numerical control machine tool. Background Technique

[0002] A numerical control machine tool is an automated device that controls the movement of the machine tool through digital information instructions. This type of machine tool is widely used in various metal processing fields, such as the automotive manufacturing, aerospace, and precision machinery industries. During the metal processing process, especially during cutting processing, a large amount of metal chips will inevitably be generated. When the machine tool uses coolant for processing, the coolant will carry the metal chips into the water tank of the machine tool. If not cleaned in time, these metal chips are likely to accumulate in large quantities in the water tank, resulting in the blockage of the water pumping port in the water tank, and further causing the coolant in the water tank to not flow back in time.

[0003] Currently, most numerical control machine tools adopt a relatively traditional chip cleaning method, that is, when the metal chips generated during the processing accumulate to a certain extent, they are cleaned regularly by manual labor. And manual cleaning requires a lot of time and manpower, especially in large processing workshops, and manual cleaning often cannot be carried out in real time, resulting in a decrease in processing efficiency. Content of the Utility Model

[0010] Further explanation: It also includes a pulley assembly. The pulley assembly is installed between the rotating shaft of the mesh chain conveyor and the cleaning brush. The pulley assembly is used for transmission between the rotating shaft of the mesh chain conveyor and the cleaning brush.

Refer to Figures 1 - 5 As shown, it includes a CNC machine tool 1 and a water tank 2; the water tank 2 is installed on the lower side of the CNC machine tool 1, and the water tank 2 is used to collect the coolant in the CNC machine tool 1;

The net chain conveyor 4 is not only used to filter the coolant that falls from the CNC machine tool 1 into the water tank 2, so that the coolant passes through the net chain conveyor 4 and is collected in the water tank 2, while the chips in the coolant remain on the net chain conveyor 4, and the net chain conveyor 4 can convey the chips into the connecting frame I 3; the servo motor 5 is installed on the rear side of the connecting frame I 3; the rotating rod 6 is rotatably installed inside the connecting frame I 3; the rear end of the rotating rod 6 is connected to the output shaft of the servo motor 5; the spiral blade 7 is installed on the rotating rod 6, and the spiral blade 7 is located inside the connecting frame I 3. By driving the rotating rod 6 and the spiral blade 7 to rotate through the servo motor 5, the spiral blade 7 can convey the chips in the connecting frame I 3 forward; the connecting frame II 8 is installed on the front side of the connecting frame I 3, and the connecting frame II 8 is communicated with the connecting frame I 3; the extrusion mechanism is used to extrude and form the chips in the connecting frame II 8, so that the chips form a cake shape; the blocking mechanism is used to block the chips in the connecting frame II 8, so as to facilitate the extrusion and forming of the chips in the connecting frame II 8.

[0023] Refer to Figure 1 、 Figure 4 and Figure 5As shown in the figure, the extrusion mechanism includes a hydraulic cylinder I 9 and an extrusion column 10; the hydraulic cylinder I 9 is installed at the lower part of the front side of the water tank 2; the extrusion column 10 is slidably installed on the right side of the connecting frame II 8, and the extrusion column 10 is connected to the telescopic rod of the hydraulic cylinder I 9, and the extrusion column 10 is used to extrude the debris in the connecting frame II 8 into a formed shape.

[0024] See Figure 1 , Figure 4 and Figure 5 As shown in the figure, the blocking mechanism includes a hydraulic cylinder II 11 and a baffle 12; both hydraulic cylinders II 11 are installed at the lower part of the front side of the connecting frame II 8, and the baffle 12 is connected between the telescopic rods of the two hydraulic cylinders II 11, and the baffle 12 is used to block the debris in the connecting frame II 8.

[0025] See Figure 2 As shown in the figure, it further includes a drying mechanism, and the drying mechanism includes a connecting frame 13 and a fan 14; the connecting frame 13 is installed on the left side of the top of the water tank 2; the fan 14 is installed on the connecting frame 13 at intervals, and by blowing air on the debris conveyed on the mesh chain conveyor 4 through the fan 14, the debris can be dried.

[0026] See Figures 4 - 6 As shown in the figure, it further includes a cleaning brush 15; the cleaning brush 15 is rotatably installed inside the connecting frame I 3, and the cleaning brush 15 is in contact with the mesh chain conveyor 4, so that the cleaning brush 15 can brush off the residual debris on the mesh chain conveyor 4.

[0027] See Figures 4 - 6 As shown in the figure, it further includes a pulley assembly 16; the pulley assembly 16 includes a pulley and a flat belt. A pulley is connected to the front side of the rotating shaft on the left side of the mesh chain conveyor 4 and the front side of the cleaning brush 15 respectively, and a flat belt is wound between the pulleys. The front side of the rotating shaft on the left side of the mesh chain conveyor 4 can drive the cleaning brush 15 to rotate through the transmission of the pulley and the flat belt.

[0028] When using the numerical control machine tool 1, start the mesh belt conveyor 4 to operate simultaneously. When the coolant in the numerical control machine tool 1 falls down into the water tank 2, the coolant will pass through the mesh belt on the mesh belt conveyor 4 for filtration, so that the coolant passes through the mesh belt conveyor 4 and is collected in the water tank 2, while the debris in the coolant remains on the mesh belt conveyor 4. Then, the mesh belt conveyor 4 can convey the debris to the left and drop it into the connecting frame I 3. Then, the servo motor 5 drives the rotating rod 6 and the spiral blade 7 to rotate, so that the spiral blade 7 conveys the debris in the connecting frame I 3 forward to the connecting frame II 8. After the debris in the connecting frame II 8 reaches a certain amount, the hydraulic cylinder I 9 drives the extrusion column 10 to move leftward, so that the extrusion column 10 extrudes and forms the debris in the connecting frame II 8, so that the debris in the connecting frame II 8 forms a cake shape, which is convenient for subsequent workers to recycle the debris. After the debris in the connecting frame II 8 is extruded and formed, the hydraulic cylinder II 11 drives the baffle 12 to move leftward, so that the baffle 12 no longer blocks the lower left side of the connecting frame II 8. At the same time, the hydraulic cylinder I 9 drives the extrusion column 10 to continue to move leftward, so that the extrusion column 10 pushes the cake-shaped debris out of the connecting frame II 8 for discharging, and then the workers collect the cake-shaped debris for recycling. Then, the hydraulic cylinder I 9 drives the extrusion column 10 to move rightward to reset, and at the same time, the hydraulic cylinder II 11 drives the baffle 12 to move rightward, so that the baffle 12 blocks the lower left side of the connecting frame II 8 again. Then, repeat the above operations to automatically clean and collect the debris generated in the numerical control machine tool 1;

[0029] When starting the mesh belt conveyor 4 to operate, the fan 14 can be started simultaneously, so that the fan 14 blows the debris conveyed on the mesh belt conveyor 4, so as to air-dry the debris to prevent too much coolant from remaining on the debris;

[0030] When the mesh belt conveyor 4 is operating, the mesh belt conveyor 4 drives the cleaning brush 15 to rotate through the pulley assembly 16, so that the cleaning brush 15 can brush off the debris remaining on the mesh belt of the mesh belt conveyor 4, and make the brushed-off debris fall into the connecting frame I 3 to prevent the debris from remaining on the mesh belt of the mesh belt conveyor 4;

[0031] When the numerical control machine tool 1 is not in use, just turn off the mesh belt conveyor 4 and the fan 14.

[0032] The above is only the specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention can easily think of changes or substitutions, which should be covered within the protection scope of the present invention.
