Description

Technical Field

[0001] This utility model relates to the field of CNC lathe technology, and in particular to a coolant filtration device for CNC lathes. Background Technology

[0002] Coolant plays a vital role in CNC lathe machining, including cooling the cutting tools and workpieces, lubricating the machining area, and flushing away chips. However, during use, the coolant can become contaminated with impurities such as chips, oil, and grinding wheel particles. Filtration equipment is needed to remove these impurities to ensure the coolant's performance and lifespan.

[0003] However, this traditional filtration method has many drawbacks. Regular cleaning of the filter elements often requires tedious disassembly due to their fixed installation, consuming significant manpower and time. More importantly, to ensure operator safety and prevent coolant leaks during filter cleaning, the CNC lathe typically needs to be temporarily shut down for protection. For modern CNC machining environments that demand high efficiency and continuous production, downtime significantly reduces processing efficiency, increases production costs, and severely restricts a company's capacity and economic benefits. Utility Model Content

[0004] This utility model aims to at least partially solve one of the technical problems in the related art.

[0005] Therefore, the purpose of this utility model is to propose a coolant filtration device for CNC lathes, which can solve the problems of operational difficulties and reduced production efficiency caused by cleaning filter elements.

[0006] To achieve the above objectives, this utility model proposes a coolant filtration device for CNC lathes, comprising a collecting bend and a connecting bend. A protective cover is installed between the collecting bend and the connecting bend. A filter ring is rotatably connected to the inner wall of the protective cover. A horizontal plate is installed on the protective cover. Both the collecting bend and the connecting bend communicate with the internal space of the protective cover, but neither the collecting bend nor the connecting bend contacts the filter ring. A plurality of inclined guide plates are installed on the inner side of the filter ring, and the plurality of inclined guide plates are arranged in a circumferential array, and none of the plurality of inclined guide plates contacts the horizontal plate.

[0007] This utility model discloses a coolant filtration device for CNC lathes. Through the combined use of a protective cover, filter ring, transverse plate, impurity storage tank, and support net, cleaning can be achieved without disassembling the filter element. The operation is simple and convenient, reducing the consumption of a lot of manpower and time. Moreover, no machine shutdown protection is required during cleaning, thus avoiding the problems of reduced processing efficiency, increased production costs, and serious constraints on enterprise capacity and economic benefits caused by machine downtime. Furthermore, the support net can release coolant trapped in the filter material, reducing coolant waste.

[0009] Specifically, a plurality of drive rods are provided on the outer side of the filter ring, and the plurality of drive rods are rotatably connected to the inner wall of the protective cover, and the side walls of the plurality of drive rods are provided with anti-slip sleeves.

[0010] Specifically, the inner wall of the protective cover is rotatably connected to two rotating rods, and several connecting ropes are fixedly connected to the side walls of the two rotating rods. One end of each connecting rope is fixedly connected to an impact ball, which contacts the side wall of the filter ring.

[0011] Specifically, the top of the horizontal plate is provided with a cleaning port, the inner wall of the cleaning port is detachably connected to a sealing door, and the sliding plate is slidably connected to the bottom of the sealing door.

[0022] The embodiments of this utility model are described in detail below. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model. Rather, the embodiments of this utility model include all variations, modifications, and equivalents falling within the spirit and scope of the appended claims.

[0023] The following describes a coolant filtration device for CNC lathes according to an embodiment of the present invention, with reference to the accompanying drawings.

[0024] like Figure 1-Figure 5 As shown, the coolant filtration device for CNC lathes in this embodiment of the present invention may include a collecting bend 1 and a connecting bend 11. A protective cover 2 is installed between the collecting bend 1 and the connecting bend 11. A filter ring 3 is rotatably connected to the inner wall of the protective cover 2. A horizontal plate 4 is installed on the protective cover 2.

[0025] Both the collecting bend 1 and the connecting bend 11 are connected to the internal space of the protective cover 2, and neither the collecting bend 1 nor the connecting bend 11 is in contact with the filter ring 3.

[0026] It should be noted that, in this embodiment, the collecting bend 1 discharges coolant laterally into the protective cover 2, and the connecting bend 11 receives the purified coolant from below the protective cover 2.

[0027] Among them, several inclined guide plates 31 are installed on the inner side of the filter ring 3. The several inclined guide plates 31 are arranged in a circular array and none of them are in contact with the horizontal plate 4.

[0028] It should be noted that the filter ring 3 described in this embodiment has the same width as the inner wall of the protective cover 2.

[0029] The horizontal plate 4 has through holes 41 at its bottom and top. A sliding plate 42 is slidably connected to the inner wall of the horizontal plate 4. A storage trough 421 is provided on the sliding plate 42. A carrying net 422 is installed on the inner wall of the storage trough 421. The carrying net 422 is flush with the bottom of the sliding plate 42.

[0030] It should be noted that the storage tank 421 described in this embodiment corresponds to the positions of the two through holes 41, and the two through holes 41 and the sliding plate 42 are all inside the protective cover 2.

[0031] Specifically, to facilitate the removal of impurities from the coolant, the collecting bend 1 is positioned below the cutting area of ​​the CNC lathe. The CNC lathe guides the coolant and debris into the collecting bend 1 via guide channels and pipes. The collecting bend 1 and the connecting bend 11 are connected by a protective cover 2 and internal components, allowing the coolant to be filtered before being driven by the circulation pump at one end of the connecting bend 11. A filter ring 3 divides the internal space of the protective cover 2. After the collecting bend 1 releases the coolant and entrained debris into the protective cover 2, it flows downwards. The coolant then smoothly passes through the filter ring 3 and enters the connecting bend 11. The circulation is completed through the pump body, which is conducive to the timely use of coolant. The filter ring 3 intercepts debris and impurities. The filter ring 3 supports and drives the rotation of several inclined guide plates 31. When rotating, the filter ring 3 can adjust the position of the filter material by rotating itself and the inclined guide plates 31. The horizontal plate 4 does not interfere with the movement of the filter ring 3 and the inclined guide plates 31. After the inclined guide plates 31 push the filter material to the upper position, they tilt. The through hole 41 is at the corresponding angle when the inclined guide plate 31 is tilted, so that debris and other filter materials can slide into the through hole 41. The impurity storage tank 421 is aligned with the through hole 41, so that the filter material and adhering debris can be removed. The coolant can enter the internal space of the impurity storage tank 421, where it is supported by the support net 422. This allows the filter ring 3 to release the filtered material in a timely manner, reducing the obstruction of the filter material's pore size and improving the recycling capacity of the filter ring 3. Furthermore, the support net 422 can release the coolant trapped in the filtered material, reducing coolant waste. When cleaning impurities in the impurity storage tank 421, the sliding plate 42 is controlled to slide towards the connecting bend 11, allowing the sliding plate 42 to move the impurities out of the protective cover 2 for cleaning. The other end of the sliding plate 42 enters the protective cover 2. At this time, the filter ring 3 and the inclined guide plate 31 temporarily place the subsequent filter material on the sliding plate 42. After the filter material in the storage tank 421 is cleaned, the sliding plate 42 slides away from the connecting bend 11, so that the filter material on the sliding plate 42 can be squeezed by the horizontal plate 4 and the protective cover 2 and re-enter the storage tank 421. Cleaning can be achieved without disassembling the filter element. The operation is simple and convenient, reducing the consumption of a lot of manpower and time. In addition, there is no need to stop the machine for protection during cleaning, thereby avoiding the problem of reduced processing efficiency and increased production costs caused by machine stoppage, which seriously restricts the enterprise's production capacity and economic benefits.

[0032] In one embodiment of this utility model, such as Figure 1-Figure 5 As shown, a number of drive rods 32 are provided on the outer side of the filter ring 3. The drive rods 32 are rotatably connected to the inner wall of the protective cover 2, and the side walls of the drive rods 32 are provided with anti-slip sleeves 33.

[0033] It should be noted that, in this embodiment, the protective cover 2 is provided with a transmission belt on one side for series transmission of several drive rods 32, the several drive rods 32 rotate synchronously, and a motor is provided on one side of the protective cover 2 to drive one of the drive rods 32.

[0034] Specifically, by controlling the motor to drive the corresponding drive rod 32 to rotate, the drive rod 32 can drive the other drive rods 32 to rotate synchronously under the action of the transmission belt. The drive rods 32 drive the filter ring 3 to rotate stably through the anti-slip sleeve 33, completing the filter ring 3's cyclic filtration. In addition, the drive rods 32 can position the filter ring 3, so that the filter ring 3 can rotate more stably in a fixed position, preventing the filter ring 3 from shifting or deviating.

[0035] In one embodiment of this utility model, such as Figure 1-Figure 5 As shown, the inner wall of the protective cover 2 is rotatably connected to two rotating rods 21. Several connecting ropes 22 are fixedly connected to the side walls of the two rotating rods 21. One end of the connecting rope 22 is fixedly connected to an impact ball 23, which contacts the side wall of the filter ring 3.

[0036] It should be noted that, in this embodiment, a motor is installed on one side of the protective cover 2 to drive two rotating rods 21, and a transmission belt is provided between the two rotating rods 21.

[0037] Specifically, the two rotating rods 21 rotate synchronously, and the rotating rods 21 rotate and swing the impact balls 23 through the connecting rope 22, so that several impact balls 23 can strike the outside of the filter ring 3, thereby causing the filter ring 3 to vibrate when it is struck, which helps the filter material on the filter ring 3 to fall off and reduce residue.

[0038] In one embodiment of this utility model, such as Figure 1-Figure 5 As shown, a cleaning port 45 is provided at the top of the horizontal plate 4, and a sealing door 451 is detachably connected to the inner wall of the cleaning port 45. A sliding plate 42 is slidably connected to the bottom of the sealing door 451.

[0039] It should be noted that the cleaning port 45 described in this embodiment corresponds to the size and position of the storage tank 421.

[0040] Specifically, the cleaning port 45 blocks the top of the storage tank 421 through the sealing door 451 to prevent external airflow from entering the internal space of the protective cover 2 through the storage tank 421. After the storage tank 421 is completely displaced out of the protective cover 2, the sliding plate 42 blocks the opening on one side of the protective cover 2. At this time, the cleaning port 45 is opened to clean the filter impurities in the storage tank 421.

[0041] In one embodiment of this utility model, such as Figure 1-Figure 5As shown, a first traction rope 43 is installed at one end of the sliding plate 42. A pull button 431 is fixedly connected to one end of the first traction rope 43. The pull button 431 contacts one side of the horizontal plate 4. A clearance groove 423 is provided at the other end of the sliding plate 42. A winding rod 44 is rotatably connected to the inner wall of the clearance groove 423. A second traction rope 441 is wound up on the side wall of the winding rod 44. One end of the second traction rope 441 is fixedly connected to the inner wall of the horizontal plate 4.

[0042] It should be noted that, in this embodiment, the first traction rope 43 and the second traction rope 441 provide opposite pulling forces to the sliding plate 42, and a spring is installed between the sliding plate 42 and the winding rod 44.

[0043] Specifically, the pull button 431 prevents the first traction rope 43 from completely entering the interior of the horizontal plate 4, making it easier for personnel to control the first traction rope 43. The first traction rope 43 pulls the sliding plate 42 to the cleaning port 45 for cleaning. At the same time, the spring between the winding rod 44 and the sliding plate 42 stores power. After cleaning, the winding rod 44 rotates under the action of the spring, so that the winding rod 44 can wind up the second traction rope 441, so that the sliding plate 42 can automatically return to its original position and maintain the stable alignment of the impurity storage tank 421 and the two through holes 41.

[0044] In summary, the coolant filtration device for CNC lathes of this utility model, when in use, collects coolant and impurities such as debris into the protective cover 2 via the collecting bend 1, and then flows downwards. The coolant smoothly passes through the filter ring 3 and enters the connecting bend 11, where it circulates through the pump, facilitating timely use of the coolant. The filter ring 3 intercepts debris and impurities. The drive rod 32 drives the filter ring 3 to rotate. During rotation, the filter ring 3 can adjust the position of the filter material by rotating itself and the inclined guide plate 31. The through hole 41 is at the corresponding angle when the inclined guide plate 31 is tilted, allowing debris and other filter materials to slide into the through hole 41. The impurity storage tank 421 and the through hole 41... The alignment allows the filtered material and adhering coolant to enter the internal space of the impurity storage tank 421. When cleaning the impurities in the impurity storage tank 421, the first traction rope 43 pulls the sliding plate 42 to the cleaning port 45 for cleaning. At the same time, the spring between the winding rod 44 and the sliding plate 42 stores power. After cleaning, the winding rod 44 rotates under the action of the spring, so that the winding rod 44 can wind up the second traction rope 441, so that the sliding plate 42 can automatically return to its position and maintain the stable alignment of the impurity storage tank 421 with the two through holes 41. Cleaning can be achieved without disassembling the filter element, which is simple and convenient to operate and reduces the consumption of a lot of manpower and time.
