Description

Technical Field

[0001] The invention relates to the technical field of water tanks, and in particular to a small water tank device and a processing center. Background Art

[0002] The water tank of the existing machining center is usually installed externally at the bottom of the machining center. It is large in size, and the circulation path of the water channel is long. The water volume and water level height difference are large. Therefore, a high-voltage (above 60V) AC pump is required to drive the flow of the water channel to achieve the cleaning work of the machining center, which leads to low cleaning efficiency of the machining center and high noise generated by the pump. In addition, the existing water tank cannot separate oil and water and recycle them, that is, the oil and water (i.e. cutting fluid) in the machining center cannot be mixed. When the machining center needs to use oil and water cross-use, the mixing will cause the processing cost to rise, so only a single processing condition (oil or water) can be used. Therefore, before each replacement of oil (or water), the water (or oil) needs to be emptied first to avoid the introduction of impurities, and the labor cost is high. 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-mentioned purpose, the technical scheme of the present invention is as follows: a small water tank device is used to be installed on a machining center, including a reflux groove, a water tank mechanism and an oil pump mechanism. The reflux groove is used to be installed on the periphery of the vise on the workbench of the machining center. The reflux groove has a water outlet. The water tank mechanism is located on one side of the workbench and is connected to the water outlet of the reflux groove. The water tank mechanism includes a solid chamber and a liquid chamber that are connected to each other. The liquid chamber includes a water-liquid chamber and an oil-liquid chamber that are connected to each other. The solid chamber is connected to the water outlet. A filter screen plate for realizing solid-liquid separation is arranged between the solid chamber and the liquid chamber, so that solid objects are intercepted and retained in the solid chamber, and liquid objects enter into the liquid chamber. A filter plate for realizing oil-water separation is arranged between the water-liquid chamber and the oil-liquid chamber, so that water is intercepted and retained in the water-liquid chamber, and oil overflows the filter plate and enters into the oil-liquid chamber. The oil-liquid chamber is connected to the oil pump mechanism through a pipeline. The oil pump mechanism is used to extract the oil in the oil-liquid chamber and transport it 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 obliquely arranged between the solid chamber and the liquid chamber, and the filter screen gradually tilts downward toward the water chamber. The part of the filter screen corresponding to the top of the water chamber is a screen structure, and the part of the filter screen corresponding to the top of the oil chamber is a solid plate structure.

[0006] In this embodiment, the water chamber and the oil chamber are arranged on the left and right, 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 one side of the water chamber close to the filter plate, and a flow channel is formed between the bottom of the flow limiting baffle and the inner bottom wall of the water chamber, and the height of the flow channel is lower than the height of the filter plate.

[0008] In this embodiment, drainage holes are respectively provided on the side wall of the water chamber away from the oil chamber and on the filter plate, and a blocking member is detachably installed in the drainage hole.

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

[0011] In this embodiment, the reflow groove is formed by splicing a plurality of detachable plates, and the reflow groove is an inverted terrace-shaped groove body with high sides and a low middle.

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

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

[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 the liquid (water and oil) shorter, and the water volume and water level height difference are smaller.

[0025] See also Figure 1-4As shown, as an embodiment of the present invention, a small water tank device is provided for installation on a machining center, including a reflux trough 3, a water tank mechanism 4 and an oil pump mechanism 5. The reflux trough 3 is used to be installed on the periphery of the vise 2 on the workbench 1 of the machining center. The reflux trough 3 has a water outlet 31. The water tank mechanism 4 is located on one side of the workbench 1 and is connected to the water outlet 31 of the reflux trough 3. The water tank mechanism 4 includes a solid chamber 41 and a liquid chamber that are connected to each other. The liquid chamber includes a water-liquid chamber 42 and an oil-liquid chamber 43 that are connected to each other. The solid chamber 41 is connected to the water outlet 31. A filter screen plate 6 for realizing solid-liquid separation is arranged between the solid chamber 41 and the liquid chamber, so that solid matter (mainly iron filings) is intercepted and retained in the solid chamber 41, and liquid matter enters the liquid chamber, and the water-liquid A filter plate 7 for achieving oil-water separation is provided between the chamber 42 and the oil chamber 43, so that the water (i.e., cutting fluid) is intercepted and retained in the water chamber 42, and the oil flows over the filter plate 7 into the oil chamber 43 (the principle of oil-water separation is that the density of the oil is less than the density of the water, so that the oil floats on the surface of the water). The oil chamber 43 is connected to the oil pump mechanism 5 through a pipeline, and the oil pump mechanism 5 is used to extract the oil in the oil chamber 43 and transport it to the processing area above the vise 2 for recycling; specifically, the oil pump mechanism 5 includes a micro 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 overall volume of the small water tank device of the present invention is small, and the structural assembly layout is more reasonable, so that the circulation path of the liquid (water and oil) is shorter, the water volume and the water level height difference are smaller, and thus there is no need to use a high-voltage AC oil pump. Instead, a micro DC oil pump can be used to extract and transport the oil to the processing area above the vise 2 for recycling, thereby achieving efficient cleaning of the machining center, improving the cleaning efficiency of the machining center, and reducing production costs. In addition, the structural setting of the water tank mechanism 4 simultaneously has the separation efficiency of solid-liquid and oil-water, that is, it realizes the sequential separation and efficient recycling of solids, water, and oil, so that the machining center can realize the cross-use of oil and water (i.e., cutting fluid) during processing, and there is no need to empty one of the liquids before adding the other liquid, thereby avoiding the introduction of impurities, simplifying the cleaning process of the machining center, and reducing labor costs.

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

[0027] In this embodiment, the solid chamber 41 is located above the liquid chamber, and the solid chamber 41 is a structure with an open top, the water chamber 42 and the oil chamber 43 are arranged horizontally, the filter screen plate 6 is tilted between the solid chamber 41 and the liquid chamber, and the filter screen plate 6 gradually tilts downward toward the water chamber 42. Specifically, the water chamber 42 and the oil chamber 43 are arranged left and right, and the inner bottom walls of the water chamber 42 and the oil chamber 43 are gradually tilted downward from left to right, so as to ensure In order to ensure the efficiency and stability of the diversion filtration, the part of the filter mesh plate 6 corresponding to the top of the water chamber 42 is a mesh plate structure, and the part of the filter mesh plate 6 corresponding to the top of the oil chamber 43 is a solid plate structure. This structural setting makes full use of the spatial volume above the liquid chamber to maximize the solid chamber 41, while ensuring that the iron filings solids, water, and oil can be accurately diverted to the solid chamber 41, the water chamber 42, and the oil chamber 43 to avoid cross mixing and ensure purity.

[0028] In this embodiment, a limiting flow baffle 8 is provided on one side of the water chamber 42 close to the filter plate 7, and an overflow channel 9 is formed between the bottom of the limiting flow baffle 8 and the inner bottom wall of the water chamber 42. The height of the overflow channel 9 is lower than the height of the filter plate 7, so that the liquid level of the liquid passing through the overflow channel 9 is lower than the filter plate 7, and then slowly rises to allow the oil to overflow the filter plate 7 and enter the oil chamber 43, thereby preventing the oil from being mixed with water and overflowing the filter plate 7 to enter the oil chamber 43, thereby ensuring the purity of the oil.

[0029] In the present embodiment, drainage 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, and a sealing member is detachably installed in the drainage hole 10. When oil-water separation work is required, the sealing member is sealed and installed in the drainage hole 10. When drainage work is required, the sealing member is removed.

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

[0031] In this embodiment, the reflux groove 3 is formed by assembling a plurality of detachable plates, and the reflux groove 3 is an inverted terraced groove with high sides and low middle, so that solid objects such as iron filings, oil or water can be collected in the reflux groove 3 to prevent splashing, so that only the area inside the reflux groove 3 needs to be cleaned during cleaning.

[0032] The small water tank device of this embodiment is a universal water tank device, so handles 11 are respectively provided on both sides of the reflux groove 3, so as to facilitate the small water tank device to be carried and installed on other processing centers.

[0033] The present invention also provides a machining center, including the small water tank device described in the above embodiment, and the machining center 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, so that the circulation path of the liquid (water and oil) is shorter, the water volume and the water level height difference are smaller, and the use of a micro DC oil pump can also extract the oil and transport it to the processing area above the vise 2 for recycling, thereby realizing efficient cleaning of the machining center, improving the cleaning efficiency of the machining center, reducing production costs, and reducing working noise.

[0035] (2) Solids, water, and oil are separated in sequence and recycled efficiently, with a high reuse rate, so that the machining center can cross-use oil and water (i.e., cutting fluid) during processing. There is no need to drain one liquid before adding another, thereby avoiding the introduction of impurities, simplifying the cleaning process of the machining center, and reducing labor costs.
