Description

Technical Field

[0001] This invention relates to the field of water tank technology, specifically to a small water tank device and machining center. Background Technology

[0002] Existing machining center water tanks are typically externally mounted at the bottom of the machining center. They are large in size, with long water circulation paths and significant differences in water volume and level. Therefore, high-voltage (above 60V) AC pumps are required to drive the water flow for cleaning, resulting in low cleaning efficiency and high pump noise. Furthermore, existing water tanks cannot separate and recycle oil and water. Oil and water (cutting fluid) cannot be mixed during machining. When mixed use is necessary, the mixing increases processing costs, limiting the use to a single processing condition (oil or water). Therefore, before each oil (or water) change, the water (or oil) must be drained to prevent the introduction of impurities, leading to high labor costs. Summary of the Invention

[0003] The present invention aims to provide a small water tank device to solve the above-mentioned technical problems.

[0004] To achieve the above objectives, the technical solution of the present invention is as follows: a small water tank device for installation on a machining center, comprising a reflux trough, a water tank mechanism, and an oil pump mechanism. The reflux trough is installed around the vise on the workbench of the machining center and has a drain outlet. The water tank mechanism is located on one side of the workbench and is connected to the drain outlet of the reflux trough. The water tank mechanism includes interconnected solid chambers and liquid chambers. The liquid chambers include interconnected water chambers and oil chambers. The solid chambers are connected to the drain outlet. A filter screen is provided between the solid chambers and the liquid chambers to achieve solid-liquid separation, so that solids are intercepted and retained in the solid chambers, and liquids enter the liquid chambers. A filter plate is provided between the water chambers and the oil chambers to achieve oil-water separation, so that water is intercepted and retained in the water chambers, and oil flows over the filter plate into the oil chambers. The oil chambers are connected to the oil pump mechanism through pipelines. The oil pump mechanism is used to extract and transport the oil in the oil chambers to the machining area above the vise for recycling.

[0005] In this embodiment, the solid chamber is located above the liquid chamber, the water chamber and the oil chamber are arranged horizontally, the filter screen is inclined between the solid chamber and the liquid chamber, and the filter screen gradually tilts downward towards the water chamber. The part of the filter screen above the water chamber is a mesh structure, and the part of the filter screen above the oil chamber is a solid plate structure.

[0006] In this embodiment, the water chamber and the oil chamber are arranged side by side, and the inner bottom walls of the water chamber and the oil chamber are gradually inclined downward from left to right.

[0007] In this embodiment, a flow-limiting baffle is provided on the side of the water chamber near the filter plate. A flow passage is formed between the bottom of the flow-limiting baffle and the inner bottom wall of the water chamber. The height of the flow passage is lower than the height of the filter plate.

[0008] In this embodiment, drain holes are respectively provided on the side wall of the water chamber away from the oil chamber and on the filter plate, and a sealing component can be detachably installed in the drain holes.

[0009] In this embodiment, the water tank mechanism further includes a receiving chamber located on the side of the oil chamber away from the water chamber. The receiving chamber includes a first receiving chamber and a second receiving chamber that are separated vertically. The first receiving chamber is used to install a power supply module, and the oil pump mechanism is installed in the second receiving chamber.

[0010] In this embodiment, the oil pump mechanism has a voltage of 24V, a head range of 6-9M, a flow rate of 1500L / h, and a power of 31.2W.

[0011] In this embodiment, the reflux trough is formed by assembling multiple detachable plates, and the reflux trough is an inverted trapezoidal trough with high sides and low middle.

[0012] In this embodiment, handles are provided on both sides of the reflux trough.

[0013] The present invention also provides a machining center, including any of the small water tank devices described above.

[0014] The present invention has the following beneficial effects:

[0015] (1) The overall volume of the small water tank device is small and the structural assembly layout is more reasonable, which makes the circulation path of liquid (water and oil) shorter, the water volume and water level height difference smaller. The micro DC oil pump can also extract and transport the oil to the processing area above the vise for circulation, thereby realizing the efficient cleaning work of the machining center, improving the cleaning efficiency of the machining center, reducing production costs, and reducing working noise.

[0016] (2) It realizes the sequential separation and efficient recycling of solids, water and oil, with a high reuse rate. This enables the machining center to use oil and water (i.e. cutting fluid) in the machining process without having to drain one liquid before adding the other, thus avoiding the introduction of impurities, simplifying the cleaning process of the machining center, and reducing labor costs.

[0025] See Figure 1-4As shown in the figure, as an embodiment of the present invention, a small water tank device is provided for installation on a machining center. It includes a return trough 3, a water tank mechanism 4, and an oil pump mechanism 5. The return trough 3 is used to install around a vise 2 on a workbench 1 of the machining center. The return trough 3 has a drain outlet 31. The water tank mechanism 4 is located on one side of the workbench 1 and is connected to the drain outlet 31 of the return trough 3. The water tank mechanism 4 includes a solid chamber 41 and a liquid chamber that are interconnected. The liquid chamber includes a water chamber 42 and an oil chamber 43 that are interconnected. The solid chamber 41 is connected to the drain outlet 31. A filter screen 6 is provided between the solid chamber 41 and the liquid chamber to achieve solid-liquid separation, so that solids (mainly iron filings) are intercepted and retained in the solid chamber 41, while liquids enter the liquid chamber, and the water... A filter plate 7 is installed between chamber 42 and oil chamber 43 to achieve oil-water separation. This allows the water (i.e., cutting fluid) to be intercepted and retained in the water chamber 42, while the oil flows over the filter plate 7 into the oil chamber 43 (the principle of oil-water separation is based on the fact that the density of oil is less than that of water, causing the oil to float on the surface of the water). The oil chamber 43 is connected to the oil pump mechanism 5 through a pipeline. The oil pump mechanism 5 is used to extract the oil from the oil chamber 43 and transport it to the machining area above the vise 2 for recycling. Specifically, the oil pump mechanism 5 includes a miniature DC oil pump with a voltage of 24V, a head range of 6-9M, a flow rate of 1500L / h, and a power of 31.2W. It has the advantages of small size, low power consumption, high efficiency, low noise (less than 30dB), and long service life. The small water tank device of this invention has a smaller overall volume and a more reasonable structural assembly layout, resulting in a shorter circulation path for the liquids (water and oil), and a smaller difference in water volume and water level. Therefore, it eliminates the need for a high-pressure AC oil pump; instead, a miniature DC oil pump can be used to extract and deliver the oil to the machining area above the vise 2 for recycling. This achieves efficient cleaning of the machining center, improves cleaning efficiency, and reduces production costs. Furthermore, the structure of the water tank mechanism 4 also provides solid-liquid and oil-water separation capabilities, enabling the sequential separation and efficient recycling of solids, water, and oil. This allows for the cross-use of oil and water (i.e., cutting fluid) during machining, eliminating the need to drain one liquid before adding the other, thus avoiding the introduction of impurities, simplifying the cleaning process, and reducing labor costs.

[0026] It should be further explained that, since the water outlet terminal of the water liquid (i.e., cutting fluid) is located on the water roller of the machining center, the water liquid chamber 42 of the present invention is connected to the water roller of the machining center through an external pipeline to complete the complete circulation process of the water liquid. The small water tank device of the present invention mainly realizes the complete circulation process of the oil liquid, and the present invention maximizes the utilization rate of oil liquid and water liquid, thereby improving the cost performance of the machine tool (machining center).

[0027] In this embodiment, the solid chamber 41 is located above the liquid chamber and has an open top. The water chamber 42 and oil chamber 43 are arranged horizontally. The filter screen 6 is inclined between the solid chamber 41 and the liquid chamber, and gradually slopes downwards towards the water chamber 42. Specifically, the water chamber 42 and oil chamber 43 are arranged left and right, and the inner bottom walls of the water chamber 42 and oil chamber 43 gradually slope downwards from left to right, thereby ensuring... To ensure the efficiency and stability of the diversion filtration, the portion of the filter plate 6 above the water chamber 42 is a mesh structure, while the portion above the oil chamber 43 is a solid plate structure. This structure makes full use of the space above the liquid chamber, maximizing the solid chamber 41, while ensuring that the iron filings, water, and oil can be accurately diverted to the solid chamber 41, water chamber 42, and oil chamber 43 respectively, avoiding cross-mixing and ensuring purity.

[0028] In this embodiment, a flow-limiting baffle 8 is provided on the side of the water chamber 42 near the filter plate 7. A flow passage 9 is formed between the bottom of the flow-limiting baffle 8 and the inner bottom wall of the water chamber 42. The height of the flow passage 9 is lower than the height of the filter plate 7, so that the liquid level of the liquid passing through the flow passage 9 is lower than that of the filter plate 7. Then it slowly rises, allowing the oil to overflow the filter plate 7 and enter the oil chamber 43. This prevents the oil mixed with water from overflowing the filter plate 7 and entering the oil chamber 43, thus ensuring the purity of the oil.

[0029] In this embodiment, drain holes 10 are respectively provided on the side wall of the water chamber 42 away from the oil chamber 43 and on the filter plate 7. A sealing component is detachably installed in the drain hole 10. When oil-water separation is required, the sealing component is installed in the drain hole 10. When draining is required, the sealing component is removed.

[0030] In this embodiment, the water tank mechanism 4 also includes a receiving chamber located on the side of the oil chamber 43 away from the water chamber 42. The receiving chamber includes a first receiving chamber 44 and a second receiving chamber 45 that are separated vertically. The first receiving chamber 44 is used to install a power supply module, and the oil pump mechanism 5 is installed in the second receiving chamber 45.

[0031] In this embodiment, the return tank 3 is formed by assembling multiple detachable plates, and the return tank 3 is an inverted trapezoidal tank with high sides and low middle, so that solids such as iron filings, oil or water can be collected in the return tank 3, preventing splashing everywhere, so that only the area inside the return tank 3 needs to be cleaned during cleaning.

[0032] The small water tank device in this embodiment is a general-purpose water tank device. Therefore, handles 11 are provided on both sides of the return channel 3 to facilitate the transport and installation of the small water tank device on other processing centers.

[0033] The present invention also provides a machining center, including the small water tank device described in the above embodiments, which has the following advantages:

[0034] (1) The overall volume of the small water tank device is small and the structural assembly layout is more reasonable, which makes the circulation path of liquid (water and oil) shorter, the water volume and water level height difference smaller. The micro DC oil pump can also draw and transport the oil to the processing area above the vise 2 for circulation, thereby realizing the efficient cleaning work of the machining center, improving the cleaning efficiency of the machining center, reducing production costs, and reducing working noise.

[0035] (2) It realizes the sequential separation and efficient recycling of solids, water and oil, with a high reuse rate. This enables the machining center to use oil and water (i.e. cutting fluid) in the machining process without having to drain one liquid before adding the other, thus avoiding the introduction of impurities, simplifying the cleaning process of the machining center, and reducing labor costs.

[0036] Although the invention has been specifically shown and described in conjunction with preferred embodiments, those skilled in the art should understand that various changes in form and detail made to the invention without departing from the spirit and scope of the invention as defined in the appended claims fall within the protection scope of the invention.
