Description

Technical Field

[0001] This utility model belongs to the field of machine tool water tank technology, and relates to a split machine tool water tank. Background Technology

[0002] To avoid problems such as workpiece thermal deformation and chip residue affecting normal processing during machine tool processing, a machine tool water tank needs to be installed to provide coolant to remove the heat and chips generated during processing, so as to maintain a suitable working temperature and a clean working area.

[0003] Traditional machine tool water tanks are usually designed as a single unit. However, for a single unit water tank, pulling the water tank out relative to the machine tool for maintenance requires a large space, which affects the space utilization of the workshop and makes it difficult to clean and repair the water tank conveniently.

[0004] To this end, Chinese patent application (application number: 202022826658.1) discloses a split-type cooling water tank for CNC machine tools, which is installed on the bed structure of the CNC machine tool. The bottom of the CNC machine tool bed is a base, and the upper part of the base is aligned with the machining area. The left side of the CNC machine tool bed is the motor drive area, the middle part of the CNC machine tool bed is the machining area, and the right side of the CNC machine tool bed is the control area. The split-type cooling water tank is located entirely within the base and includes a funnel-shaped opening aligned with the heat dissipation cavity of the machining area, a water tank, a water delivery trough, and a collection trough. The collection trough is located below the funnel-shaped opening and slopes from below the control area towards the funnel-shaped opening. The bottom of the collection trough is located below the funnel-shaped opening. The unit consists of an isolation mesh panel, with a water supply trough below the collection trough. The upper part of the water supply trough is open, and the upper part of the left side section of the water supply trough is aligned with the isolation mesh panel. The right side opening of the rear part of the water supply trough connects to the water inlet on the front side of the water tank. The water supply trough and the water tank are arranged in an L-shape. The water tank is located below the control area. The water supply trough is connected to the base by pulling it back and forth, and the water tank is connected to the base by pulling it left and right. A through hole is provided on the top of the water tank. An inspection door is provided on the side of the base corresponding to the top of the water tank, and a cleaning door is provided on the side of the base corresponding to the right end of the collection trough.

[0005] However, the above method has the following drawbacks: 1. The water supply tank is connected to the base by pulling back and forth, and the water tank is connected to the base by pulling left and right. During the repeated pulling of the water supply tank and the water tank, the connection between the water supply tank and the water tank is prone to small gaps due to mechanical wear. Moreover, metal debris in the cutting fluid may be embedded in the sliding track, damaging the flatness of the contact surface, resulting in poor sealing effect and low stability. 2. The collection tank slopes from the bottom of the control area towards the funnel opening. Below the collection tank is the water delivery tank, which has an opening at the top and an opening on the right side of the rear of the water delivery tank that connects to the water inlet on the front side of the water tank. The water delivery tank and the water tank are arranged in an L-shape. Cutting chips in the cutting fluid tend to accumulate at the corner of the L-shape. Moreover, when a large amount of cutting fluid rushes into the water delivery tank, the flow direction will change drastically due to the right angle transition at the corner of the L-shape. This will not only cause the liquid flow rate to decrease, making it difficult to flow smoothly into the water tank, but also easily cause wear on the side wall, resulting in poor sealing effect and low stability. Utility Model Content

[0006] The purpose of this utility model is to address the aforementioned problems in existing technologies by proposing a split machine tool water tank. The technical problem to be solved by this utility model is: how to achieve excellent and reliable sealing performance of the water tank.

[0007] The objective of this utility model can be achieved through the following technical solution: A split machine tool water tank, comprising a tank body with an open upper part, characterized in that the tank body is provided with a cover plate and a partition plate vertically connected to the upper side of the cover plate, the cover plate is provided with a filter screen, and the cover plate divides the inner cavity of the tank body into an upper water collection chamber and a lower water storage chamber, the side plate of the tank body, the partition plate and the cover plate together form a water guide groove, the water guide groove is provided with a drain port communicating with the water storage chamber, the two side walls of the water guide groove are respectively provided with installation notches, the tank body is detachably connected with a water collection plate, one end of the water collection plate abuts against the installation notch and extends into the water collection chamber, and the two installation notches are respectively provided with sealing strips that seal with the water collection plate.

[0008] The water collection plate is detachably connected to the housing, and its position can be flexibly adjusted to allow space for the housing to move relative to the machine tool body. The two side walls of the water guide channel have installation notches, meaning the side panels and partitions of the housing each have corresponding installation notches. Sealing strips that seal with the water collection plate are installed at each of the two installation notches. The upper part of the water collection cavity is open. The side panels, partitions, and cover plate of the housing together form the water guide channel, which extends circumferentially around the housing. In practical operation, the cutting fluid on the machine tool can flow directly into the water collection chamber through the opening at the top, or indirectly through the water collection plate. During this process, some cutting fluid may splash due to impact or overflow due to accumulation. Most of the splashed and overflowing cutting fluid, as well as the cutting fluid that flows into the water collection chamber, is blocked by the sealing strip near the inner side of the chamber. After being filtered by the filter screen on the cover, it enters the water storage chamber. A small portion enters the water guide channel and is blocked by the sealing strip near the outer side of the chamber, thus remaining in the water guide channel and flowing into the water collection chamber through the drain outlet. The two sealing strips form a double sealing structure. The sealing strip near the inner side of the chamber acts as the first layer of sealing, blocking most of the cutting fluid. When the first layer of sealing fails, the sealing strip near the outer side of the chamber acts as the second layer of sealing. The first layer of sealing bears most of the pressure and wear, while the second layer of sealing provides backup protection. This double insurance prevents cutting fluid leakage at the connection between the water collection plate and the chamber, contributing to excellent and reliable sealing of the water tank. The path of the cutting fluid collected by the water collection plate to the water collection chamber is unobstructed, preventing liquid splashing due to impact. Furthermore, the large space within the water collection chamber provides ample room for the fluid to decelerate and dissipate pressure. The cutting fluid then passes through a filter screen and enters the water storage chamber under gravity. This prevents excessive impact on the inner wall of the tank, which could lead to wear and leakage. Simultaneously, the water guide channel extends circumferentially around the tank, effectively collecting any splashed or overflowing cutting fluid, ensuring excellent and reliable sealing of the water tank. Installation notches for the water collection plate are provided on both sides of the water guide channel. These notches position the water collection plate during installation. When the cutting fluid collects on the water collection plate, gravity presses the plate against the opening of the water guide channel, i.e., the upper surface of the installation notch, contributing to an excellent and reliable seal between the water collection plate and the sealing strip.

[0009] In the aforementioned split-type machine tool water tank, the cross-section of the water collection plate is U-shaped, and the sealing strip is correspondingly U-shaped. The shape of the sealing strip matches the shape of the water collection plate, allowing the sealing strip to better fit the bottom and side plates of the water collection plate, which helps to achieve uniform pressure distribution and thus excellent and reliable sealing. When the cutting fluid gathers on the water collection plate, the gravity of the liquid presses the water collection plate into the guide groove opening and also against the bottom of the U-shaped sealing strip, which helps to more reliably press the bottom plate of the water collection plate and the bottom of the U-shaped sealing strip together for a tighter seal. At the same time, when the cutting fluid flows on the water collection plate, it may cause slight vibrations in the width direction of the water collection plate. The two sides of the U-shaped sealing strip can cooperate with each other to compensate for the slight displacement or deformation of the side plates of the water collection plate, making the connection between the water collection plate and the tank stable and ensuring the sealing effect at the connection, thereby achieving excellent and reliable sealing of the water tank.

[0010] In the aforementioned split-type machine tool water tank, the sealing strip is detachably connected to the wall of the water guide channel to form a seal. The sealing strip also has a lip that abuts against the outer wall of the water collection plate for a tight seal. The angle between the plane of the lip and the plane of the sealing strip body is an obtuse angle, providing elastic deformation space for the water collection plate to accommodate minor displacements or deformations caused by vibration or thermal deformation. The lip and the sealing strip body can swing slightly relative to each other, effectively absorbing and compensating for mechanical impacts or deformations through elastic deformation, ensuring excellent and reliable sealing performance. The sealing strip is detachably connected to the wall of the water guide channel, rather than to the water collection plate. The water guide channel, as a fixed structure, provides a stable and reliable installation reference for the sealing strip, thus facilitating accurate and stable installation of the water collection plate. Furthermore, if wear causes poor sealing performance, the sealing strip can be replaced without repairing the entire water guide channel, which is convenient and cost-effective.

[0011] In the aforementioned split-type machine tool water tank, the partition is located inside the tank, dividing the internal cavity of the tank, located above the cover plate, into a water collection chamber and a water guide channel. The drain outlet is located at the bottom of the water guide channel. The internal cavity of the tank, located above the cover plate, is divided by the partition, with the smaller side serving as the water guide channel and the larger side as the water collection chamber. This fully utilizes the tank's structure, improves space utilization, and makes the structure compact. Simultaneously, at the location of the water guide channel, the partition and the tank side plate form a double-layer structure. The space between the partition and the tank not only provides a buffer space for vibration but also a compensation space for deformation.

[0012] The aforementioned split-type machine tool water tank has an L-shaped baffle that bends outward at the upper end of the partition. The upper end of the partition bends outward, which is also the inner side of the guide water channel, maintaining the same floor space at the bottom of the tank. This expands the contact surface for blocking the cutting fluid in both the vertical and horizontal directions, improving the cutting fluid recovery rate. Simultaneously, the cutting fluid blocked by the baffle can, under gravity, converge along the outer wall of the guide water channel into the water collection chamber, and then, after being filtered by the filter screen on the cover, enter the water storage chamber.

[0013] The aforementioned split-type machine tool water tank has an L-shaped baffle two that bends outward at the upper end of the side plate of the tank body, with the outer end of the second baffle located outside the first baffle. The first baffle forms a first layer of obstruction, and the second baffle forms a second layer of obstruction. Splashing cutting fluid is first blocked by the first layer of obstruction and collects in the water collection chamber. Cutting fluid that flies over the first layer of obstruction is further blocked by the second layer of obstruction. Under the action of gravity, it collects along the inner wall of the water guide channel to the bottom of the water guide channel and enters the water storage chamber through the drain port one.

[0014] The aforementioned split-type machine tool water tank includes several drain outlets (II) connected to the water storage chamber at the bottom of the water guide channel. The opening of drain outlet I is larger than that of drain outlet II. Drain outlet I is located below the water collection plate, and drain outlet II are distributed sequentially along the length of the water guide channel. Since the water collection plate catches the cutting fluid and guides it into the water collection chamber, the area near the water collection plate may contain a large amount of cutting fluid, which can easily overflow or splash into the water guide channel. Therefore, drain outlet I with a larger opening is provided at the bottom of the water guide channel below the water collection plate to quickly drain the accumulated cutting fluid. Simultaneously, several drain outlets II with smaller openings are provided along the length of the water guide channel to assist drain outlet I and improve the efficiency of cutting fluid entering the water storage chamber. The reasonable size and placement of drain outlets I and II not only avoid the problem of cutting fluid accumulation but also effectively ensure structural strength, thereby contributing to excellent and reliable sealing.

[0015] In the aforementioned split-type machine tool water tank, the end of the water collecting plate that extends into the water collecting cavity is inclined downwards. The water collecting plate catches the cutting fluid, and under the action of gravity, the cutting fluid flows into the water collecting cavity along the inclined direction of the water collecting plate, effectively avoiding the problems of cutting fluid accumulation and overflow, thus contributing to excellent and reliable sealing performance.

[0016] The aforementioned split-type machine tool water tank has a detachable filter basket on its cover plate. The bottom of the filter basket extends into the water storage chamber, and both the bottom plate and side plate of the filter basket have several filter holes. When the filter screen becomes clogged, the cutting fluid can flow to the filter basket and enter the water storage chamber through the filter holes, effectively avoiding the problems of cutting fluid accumulation and overflow, thus contributing to excellent and reliable sealing performance.

[0017] The aforementioned split-type machine tool water tank has several reinforcing plates extending along the width of the tank within its water storage chamber. These reinforcing plates are fixedly connected to the bottom and side plates of the tank, with their upper ends abutting against partitions. The reinforcing plates effectively improve the tank's strength, divide the water storage chamber into several spaces, distribute the liquid pressure, and prevent tank deformation.

[0018] Compared with existing technologies, the water tank of this machine tool has the following advantages:

[0019] 1. In this split-type machine tool water tank, two sealing strips form a double sealing structure. The sealing strip closer to the inner side of the tank acts as the first layer of sealing, blocking most of the cutting fluid. When the first layer of sealing fails, the sealing strip closer to the outer side of the tank acts as the second layer of sealing. The first layer of sealing bears most of the pressure and wear, while the second layer of sealing provides backup protection. This double protection prevents cutting fluid from leaking at the connection between the water collection plate and the tank, which helps to make the water tank's sealing effect excellent and reliable.

[0020] 2. In this split-type machine tool water tank, the path of the cutting fluid collected by the water collection plate to the water collection chamber is unobstructed, avoiding liquid splashing due to impact. In addition, the cutting fluid enters the water collection chamber, which has a large space, allowing sufficient space for the liquid to decelerate and unload. Then, the cutting fluid is filtered through the filter screen and enters the water storage chamber under the action of gravity. This avoids excessive impact on the inner wall of the tank, which could lead to wear and leakage. At the same time, the water guide groove extends along the circumference of the tank, which is conducive to the full collection of cutting fluid splashed or overflowed along the circumference of the tank, and helps to make the water tank have excellent and reliable sealing effect.

[0021] 3. In this split machine tool water tank, the two sides of the water guide groove are respectively provided with installation notches for the water collection plate to pass through. The installation notches play a positioning role in the installation of the water collection plate. When the cutting fluid gathers on the water collection plate, the gravity of the liquid will press the water collection plate into the water guide groove opening, that is, the upper surface of the installation notch, which helps to make the sealing fit between the water collection plate and the sealing strip excellent and reliable.

Detailed Implementation

[0031] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0032] The specific embodiments described herein are merely illustrative examples illustrating the spirit of this utility model. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.

[0033] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 8 It can be seen that this split machine tool water tank includes a box body 1 with an open upper part, and the box body 1 can be detachably installed on the machine tool.

[0034] The inner side of the housing 1 is provided with a cover plate 2 and a partition plate 3 vertically connected to the upper side of the cover plate 2. The cover plate 2 extends horizontally and divides the inner cavity of the housing 1 into an upper water collection chamber 4 and a lower water storage chamber 5. The partition plate 3 extends circumferentially around the housing 1 and divides the inner cavity of the housing 1 located above the cover plate 2 into a water collection chamber 4 and a water guide channel 6. Specifically, one side of the partition plate 3, together with the inner wall of the housing 1 and the upper side of the cover plate 2, forms a water guide channel 6, and the other side of the partition plate 3, together with the inner wall of the housing 1 and the upper side of the cover plate 2, forms a water collection chamber 4. The upper side of the water collection chamber 4 is open, and the lower side of the cover plate 2, together with the inner wall of the housing 1, forms a water storage chamber 5. The inner cavity of the housing 1 located above the cover plate 2 is divided by the partition plate 3, with the smaller side being the water guide channel 6 and the larger side being the water collection chamber 4. This makes full use of the structure of the housing 1 itself, improves space utilization, and makes the structure compact. At the same time, at the location of the water guide channel 6, the baffle 3 and the side plate of the box 1 form a double-layer structure. The space between the baffle 3 and the box 1 not only provides a buffer space for vibration, but also provides a compensation space for deformation.

[0035] The partition 3, the side panel of the box 1, and the cover 2 together form a water guide channel 6, which extends around the circumference of the box 1. Specifically, the water guide channel 6 can extend along the length of the box 1 in a long strip shape, or it can extend along both the length and width of the box 1 in an L-shape.

[0036] The bottom of the water guide channel 6 is provided with a drain outlet 7 and several drain outlets 11 that communicate with the water storage chamber 5. The opening of drain outlet 7 is larger than the opening of drain outlet 11. Drain outlet 7 is located below the water collection plate 9, and drain outlets 11 are distributed sequentially along the length of the water guide channel 6. Since the water collection plate 9 catches the cutting fluid and guides it into the water collection chamber 4, there may be a lot of cutting fluid in the area of ​​the water collection chamber 4 near the water collection plate 9. The cutting fluid is prone to overflow or splashing into the water guide channel 6 at this location. Therefore, a drain outlet 7 with a larger opening is provided at the bottom of the water guide channel 6 below the water collection plate 9 to quickly drain the accumulated cutting fluid. At the same time, several drain outlets 11 with smaller openings are provided along the length of the water guide channel 6 to assist drain outlet 7 and improve the efficiency of cutting fluid entering the water storage chamber 5 from the water guide channel 6. The reasonable size planning and location layout of drain outlet 17 and drain outlet 21 not only avoids the problem of cutting fluid accumulation, but also effectively ensures structural strength, which in turn helps to achieve excellent and reliable sealing performance.

[0037] The upper end of the partition 3 has an L-shaped baffle 3a that bends inward to guide the water channel 6. That is, the upper end of the partition 3 bends outward to form the baffle 3a. While keeping the bottom area of ​​the box 1 unchanged, the contact surface for blocking the cutting fluid is expanded in both the height and lateral directions, thereby improving the recovery rate of the cutting fluid. At the same time, the cutting fluid blocked by the baffle 3a can be collected in the water collection chamber 4 along the outer wall of the water channel 6 under the action of gravity, and then filtered through the filter screen 2a on the cover plate 2 before entering the water storage chamber 5.

[0038] The upper end of the side plate of the housing 1 has an L-shaped baffle 2 1a that bends outward. The outer end of the baffle 2 1a is located outside the baffle 1 3a. That is, the upper end of the side plate of the housing 1 bends outward to form the baffle 2 1a. The baffle 1 3a forms the first barrier, and the baffle 2 1a forms the second barrier. The splashing cutting fluid is first blocked by the first barrier and gathers into the water collection chamber 4. The cutting fluid that flies over the first barrier is further blocked by the second barrier. Under the action of gravity, it gathers along the inner wall of the water guide channel 6 to the bottom of the water guide channel 6 and enters the water storage chamber 5 through the drain outlet 1 7.

[0039] The two side walls of the water guide channel 6 are respectively provided with U-shaped installation notches 8, that is, the side plates and partitions of the housing 1 are respectively provided with corresponding installation notches 8. The housing 1 is detachably connected to a water collection plate 9. The cross-section of the water collection plate 9 is U-shaped, and the end of the water collection plate 9 that extends into the water collection cavity 4 is inclined downwards. The water collection plate 9 catches the cutting fluid, and under the action of gravity, the cutting fluid flows towards the water collection cavity 4 along the inclined direction of the water collection plate 9, effectively avoiding the problem of cutting fluid accumulation and overflow, thus contributing to excellent and reliable sealing performance.

[0040] Specifically, one end of the water collecting plate 9 abuts against the mounting notch 8 and extends into the water collecting cavity 4. Sealing strips 10, which seal with the water collecting plate 9, are respectively provided at the two mounting notches 8. That is, U-shaped sealing strips 10, corresponding to the shape of the water collecting plate 9, are respectively provided on the outer sides of the two side walls of the water guiding groove 6. These two sealing strips 10 are located in the water collecting cavity 4 inside the housing 1 and on the outer side of the housing 1. The shape of the sealing strip 10 matches the shape of the water collecting plate 9, allowing the sealing strip 10 to better fit the bottom plate and side plates of the water collecting plate 9, which helps to achieve uniform pressure distribution and thus excellent and reliable sealing. When the cutting fluid gathers on the water collecting plate 9, the gravity of the liquid presses the water collecting plate 9 against the opening of the water guiding groove 6 and also against the bottom of the U-shaped sealing strip 10, which helps to more reliably press the bottom plate of the water collecting plate 9 against the bottom of the U-shaped sealing strip 10 for a tight seal. At the same time, when the cutting fluid flows on the water collection plate 9, it may cause the water collection plate 9 to vibrate slightly in the width direction. The two sides of the U-shaped sealing strip 10 can cooperate with each other to compensate for the slight displacement or deformation of the side plate of the water collection plate 9, so that the water collection plate 9 is stably connected to the tank body 1 and the sealing effect of the connection is guaranteed, thereby achieving excellent and reliable sealing of the water tank.

[0041] The outer wall of the water collecting plate 9 is sealed to the two sealing strips 10 mentioned above. Specifically, the sealing strip 10 also has a lip 10a that abuts against the outer wall of the water collecting plate 9. The angle between the plane of the lip 10a and the plane of the sealing strip 10 body is an obtuse angle. The sealing strip 10 body is detachably connected to the wall of the water guide groove 6 to form a seal, for example, by using fastening screws to achieve a detachable connection. The lip 10a abuts against the outer wall of the water collecting plate 9. The obtuse angle between the plane of the lip 10a and the plane of the sealing strip 10 body provides elastic deformation space for the small displacement or deformation of the water collecting plate 9 due to vibration or thermal deformation. The lip 10a and the sealing strip 10 body can swing slightly relative to each other. Through elastic deformation, mechanical impact or deformation is effectively absorbed and compensated, ensuring excellent and reliable sealing effect. The sealing strip 10 is detachably connected to the wall of the water guide channel 6, rather than to the water collection plate 9. The water guide channel 6, as a fixed structure, provides a stable and reliable installation reference for the sealing strip 10, thereby facilitating the accurate and stable installation of the water collection plate 9. Furthermore, if wear occurs and leads to poor sealing performance, the sealing strip 10 can be replaced without repairing the entire water guide channel 6, which is convenient and cost-effective.

[0042] The water storage chamber 5 is equipped with several reinforcing plates 12 extending along the width of the housing 1. These reinforcing plates 12 are fixedly connected to the bottom plate and side plates of the housing 1, and their upper ends abut against the partition plates 3. The reinforcing plates 12 effectively increase the strength of the housing 1, divide the water storage chamber 5 into several spaces, distribute the liquid pressure, and prevent deformation of the housing 1. Windows are also provided on the reinforcing plates 12, allowing the cutting fluid to flow within the spaces separated by the reinforcing plates 12 in the water storage chamber 5.

[0043] The cover is detachably equipped with a filter screen 2a and a filter basket 2b. The bottom of the filter basket 2b extends into the water storage chamber 5, and both the bottom plate and side plate of the filter basket 2b have several filter holes. The filter holes of the filter screen 2a and the filter basket 2b are connected to the water collection chamber 4 and the water storage chamber 5. Specifically, the cover has mounting holes for the filter screen 2a and the filter basket 2b, which can be easily inserted into the corresponding mounting holes. They can be removed when cleaning or replacement is needed. When the filter screen 2a becomes blocked, the cutting fluid can flow to the filter basket 2b and enter the water storage chamber 5 through the filter holes, effectively avoiding the problem of cutting fluid accumulation and overflow, thus contributing to excellent and reliable sealing.

[0044] The machine tool is also equipped with a water pump assembly, and casters are installed at the bottom of the housing 1. If it is necessary to pull out the water tank for maintenance or cleaning, the position of the water collection plate 9 can be adjusted flexibly to make room for the housing 1 to move relative to the machine tool body.

[0045] In actual operation, the cutting fluid on the machine tool can be directly collected into the water collection chamber 4 through the opening at the top of the water collection chamber 4, or indirectly collected by the water collection plate 9 and then collected into the water collection chamber 4. During this process, the cutting fluid may splash due to impact or overflow due to accumulation. Most of the splashed and overflowed cutting fluid and the cutting fluid collected into the water collection chamber 4 are blocked in the water collection chamber 4 by the sealing strip 10 near the inner side of the housing 1. After being filtered by the filter screen 2a or filter basket 2b on the cover plate 2, it enters the water storage chamber 5. A small part enters the water guide groove 6 and is blocked by the sealing strip 10 near the outer side of the housing 1. It then stays in the water guide groove 6 and flows into the water collection chamber 4 through the drain outlet 1 7 or drain outlet 2 11.

[0046] The two sealing strips 10 form a double sealing structure. The sealing strip 10 closer to the inner side of the tank 1 plays the role of the first sealing, blocking most of the cutting fluid. When the first sealing fails, the sealing strip 10 closer to the outer side of the tank 1 plays the role of the second sealing. The first sealing bears most of the pressure and wear, while the second sealing provides backup protection. This double insurance prevents the cutting fluid from leaking at the connection between the water collection plate 9 and the tank 1, which helps to make the water tank's sealing effect excellent and reliable. The path of the cutting fluid collected by the water collection plate 9 to the water collection chamber 4 is unobstructed, preventing liquid splashing due to impact. Furthermore, the water collection chamber 4 has a large space, providing ample room for the liquid to decelerate and dissipate force. The cutting fluid then passes through the filter screen 2a and enters the water storage chamber 5 under gravity. This prevents excessive impact on the inner wall of the tank 1, which could lead to wear and leakage. Simultaneously, the water guide channel 6 extends circumferentially along the tank 1, effectively collecting any cutting fluid splashed or overflowing along the circumference, ensuring excellent and reliable sealing of the water tank. The two side walls of the water guide channel 6 have installation notches 8 for the water collection plate 9 to pass through. These notches 8 position the water collection plate 9 during installation. When the cutting fluid gathers on the water collection plate 9, the gravity of the liquid presses the water collection plate 9 into the opening of the water guide channel 6, i.e., the upper surface of the installation notch 8, contributing to excellent and reliable sealing between the water collection plate 9 and the sealing strip 10.

Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.

[0048] Although this document frequently uses terms such as housing 1, baffle 2 1a, cover 2, filter screen 2a, filter basket 2b, partition 3, baffle 1 3a, water collection chamber 4, water storage chamber 5, water guide channel 6, drain outlet 1 7, installation notch 8, water collection plate 9, sealing strip 10, baffle 10a, drain outlet 2 11, and reinforcing plate 12, the possibility of using other terms is not excluded. The use of these terms is merely for the convenience of describing and explaining the essence of this utility model; interpreting them as any additional limitation would contradict the spirit of this utility model.
