Description

Technical Field

[0001] The utility model relates to the technical field of numerical control machining, in particular to a cleaning mechanism for numerical control machining. Background Technique

[0002] Numerical control machining is a high-efficiency automatic machine tool composed of mechanical equipment and a numerical control system, suitable for machining complex parts. Numerical control machining is one of the numerically controlled machine tools with the highest output and the widest application in the world at present. It has strong comprehensive machining capabilities. After the workpiece is clamped once, it can complete more machining contents, and the machining accuracy is relatively high. It can complete machining that many ordinary equipment cannot complete, and is more suitable for single-piece machining with relatively complex shapes and high precision requirements or multi-variety production in small and medium batches. It integrates functions such as milling, boring, drilling, tapping, and threading on one device, making it have a variety of processing means. However, a large amount of waste chips will be generated during the numerical control machining process. Irregular cleaning of the waste chips will not only affect the machining work, but also the long-term accumulation of waste chips in the gaps will cause wear and damage to the equipment components, resulting in the equipment being unable to be used.

[0003] For example, in the utility model with the application number 202221863778.1, a cleaning mechanism for a numerical control machining center is disclosed. In the utility model, by setting an inlet and outlet, a mounting plate, a concave placement groove, and a filter screen, the cutting fluid is filtered. When the waste chips need to be cleaned after the numerical control machining center body has run for a period of time, rotate the L-shaped clamping rod so that the L-shaped clamping rod moves out of the limit groove, and then hold the handle to pull the mounting plate out of the numerical control machining center body, and then take out the filter screen to take the waste chips in the filter screen out of the numerical control machining center body, so that the staff can clean the waste chips, which can effectively improve the efficiency of waste chip cleaning in the numerical control machining center, and the cleaning process is convenient, reducing the labor intensity of the staff. At the same time, the movement of the mounting plate can also drive the scraping head to scrape the cutting fluid accumulated at the bottom of the numerical control machining center body into the bottom box through the discharge port for centralized treatment.

[0004] The similar applications currently still have deficiencies:

[0005] This kind of cleaning mechanism for the numerical control machining center only collects and cleans the waste chips that fall during the numerical control machining process, but the waste chips on the machining table cannot be cleaned, and manual flushing and cleaning are required, resulting in a large workload. Secondly, the area of the filter screen used is too large, which not only increases the cleaning area and the cleaning time of the staff, but also the large floor area will cause a large amount of liquid to drip on the ground, bringing inconvenience to the cleaning work of people.

[0006] Therefore, a cleaning mechanism for numerical control machining is designed to optimize the above problems. Content of the Utility Model

[0025] To make the technical solutions of the present utility model clearer and more definite to those skilled in the art, the present utility model will be further described in detail below in conjunction with embodiments and drawings. However, the implementation manners of the present utility model are not limited thereto.

[0026] As Figures 1 - 4 shown, this embodiment provides a cleaning mechanism for numerical control machining, including a cleaning bin 1. On one side of the cleaning bin 1, a positive and negative motor 2 is symmetrically installed. Output shafts of the positive and negative motors 2 are both fixed with bidirectional lead screws 3, and ends of the bidirectional lead screws 3 all penetrate and extend into the interior of the cleaning bin 1. Outer sides of the bidirectional lead screws 3 are both symmetrically threadedly connected with sliders 4, and the sliders 4 are slidably connected with the inner side wall of the cleaning bin 1. Inside the cleaning bin 1, fixed rods 5 are symmetrically arranged, and two ends of the fixed rods 5 are respectively fixedly connected with the sliders 4. Outer sides of two ends of the fixed rods 5 are both sleeved with limit rings 22, and the limit rings 22 are slidably connected with baffles 21. The arrangement of the limit rings 22 improves the wear resistance of the fixed rods 5 and is slidably connected with the baffles 21. By means of the baffles 21, the supporting force for the fixed rods 5 is increased, and the stability of the fixed rods 5 is improved. On the outer side of one end of the fixed rod 5, a support frame 6 is fixed. On one side of the top of the support frame 6, an extension plate 7 is fixed. At the bottom of the cleaning bin 1, a water collecting bin 13 is fixed. On one side of the water collecting bin 13, a high-pressure water pump 9 is installed. An inlet liquid pipe 12 is fixed to the input end of the high-pressure water pump 9, and the end of the inlet liquid pipe 12 penetrates and extends into the interior of the water collecting bin 13. An outlet liquid pipe 10 is fixed to the output end of the high-pressure water pump 9. Hose pipes 11 are respectively installed at the ends of the outlet liquid pipe 10. At the top of the hose pipes 11, high-pressure spray nozzles 8 are installed, and the tops of the high-pressure spray nozzles 8 are fixedly connected with the bottom of the extension plate 7. A collecting assembly 14 is arranged between the fixed rod 5 and the cleaning bin 1.

[0027] Specifically, start the positive and negative motor 2 and the high-pressure water pump 9. The high-pressure water pump 9 conveys the liquid in the water collecting bin 13 to the hose pipes 11 and sprays it on the workbench through the high-pressure spray nozzles 8. The impact force flushes the waste chips on the workbench into the interior of the cleaning bin 1. At the same time, the positive and negative motor 2 drives the bidirectional lead screw 3 to rotate, so that the sliders 4 drive the sliders 4 and the fixed rods 5 to move horizontally back and forth under the limitation of the inner wall of the cleaning bin 1, and then drive the support frame 6, the extension plate 7 and the high-pressure spray nozzles 8 to move, so as to flush and clean the waste chips at different positions on the workbench until the waste chips on the workbench are cleaned up. The cleaned waste chips enter the cleaning bin 1 together with the flushing liquid and are collected by the cleaning bin 1.

[0028] As Figure 1 and Figure 4As shown, the collection component 14 includes a collection port 15, an L-shaped plate 16, and a movable plate 19. The collection ports 15 are evenly opened at the bottom of the cleaning bin 1. Inside both ends of the collection port 15, inclined plates 23 are symmetrically installed, and a protective layer is provided on the inclined plates 23. Further, the waste chips are guided to the inside of the filter screen frame 17 through the inclined plates 23, promoting the unified collection of waste chips, reducing liquid and chip leakage. At the bottom of the collection port 15, L-shaped plates 16 are symmetrically installed, and the top of the L-shaped plates 16 is fixedly connected to the bottom of the cleaning bin 1. A filter screen frame 17 is slidably installed between the L-shaped plates 16. The movable plates 19 are respectively installed on the outer sides of the fixed rods 5. Brushing plates 18 are fixed to the bottoms of the movable plates 19, and the bottoms of the brushing plates 18 are movably connected to the inner bottom wall of the cleaning bin 1. A support plate is fixed between one side of the movable plate 19 and above the brushing plate 18, and the support plate is a triangular support plate. The triangular support plate is connected to the brushing plate 18 and the movable plate 19 respectively, improving the stability between the two.

[0029] Specifically, when the fixed rod 5 moves, it drives the brushing plate 18 and the movable plate 19 to move, causing the brushing plate 18 to horizontally move left and right to push the waste chips inside the cleaning bin 1 into the filter screen frame 17. After being filtered by the filter screen frame 17, the waste chips are left inside the filter screen frame 17. Then, according to the amount of waste chips accumulated in the filter screen frame 17, the filter screen frame 17 with more waste chips is pulled out from the L-shaped plate 16 for cleaning.

[0030] As Figure 1 and Figure 3 shown, inside the cleaning bin 1, guide plates 20 are symmetrically installed, and the guide plates 20 are respectively located above the bidirectional lead screw 3. On one side of each guide plate 20, a retaining strip is provided, and the guide plates 20 are all inclined in the cleaning bin 1. The inclined guide plates 20 facilitate the splashed liquid to slide down from the guide plates 20 into the cleaning bin 1. The retaining strips further improve the effect of protecting against splashing. Inside the cleaning bin 1 and at the position below the bidirectional lead screw 3, baffles 21 are fixedly installed.

[0031] Specifically, the guide plates 20 and the baffles 21 respectively protect the top and bottom of the bidirectional lead screw 3, reducing the splashing of liquid onto the outside of the bidirectional lead screw 3, which may cause pollution to the bidirectional lead screw 3, resulting in corrosion and damage to the bidirectional lead screw 3.

[0032] The above is only a further embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the scope disclosed by the present utility model, according to the technical solution and its concept of the present utility model, makes equivalent replacements or changes, all belong to the protection scope of the present utility model.
