Description
Technical Field
[0001] This utility model relates to the field of coolant tank filtration technology, and in particular to a filtration and circulation structure for coolant tanks in CNC machine tools. Background Technology
[0002] The coolant tank of a CNC machine tool is the core liquid storage and pretreatment unit of the CNC machine tool cooling system. Its main functions are to store and filter coolant, and to provide a stable supply of coolant for cooling, lubrication and chip removal in the machine tool's machining area. It is a key component to ensure high-precision machining of CNC machine tools, extend tool life and maintain stable equipment operation. When the coolant enters the coolant tank and is discharged from the CNC machine tool, a filter box is usually installed to intercept impurities. The filtered coolant then enters the tank and can be pumped away by the cooling pump, so that the filtered coolant can be circulated in the tank and supplied to the CNC machine tool for machining.
[0003] Existing CNC machine tool coolant tanks typically only use a simple metal filter box at the coolant recovery port for filtration during coolant circulation. This simple filtration structure is ineffective, leading to the accumulation of impurities in the tank. Frequent use of a tank deslagging machine to remove the tank cover is necessary, making the use of a coolant tank capable of circulating and filtering coolant inconvenient. Therefore, we propose a new filtration and circulation structure for CNC machine tool coolant tanks. Utility Model Content
[0004] The main objective of this invention is to provide a filtration and circulation structure for a CNC machine tool coolant tank. A support frame is installed at the bottom of the coolant tank for assembling the filtration mechanism. The bottom filter box of the filtration mechanism achieves preliminary filtration through filter holes on all four sides and at the bottom, intercepting most suspended impurities. An internal magnetic rod, stably mounted with a U-shaped frame, accurately adsorbs ferromagnetic metal shavings in the coolant, reducing the burden of metal impurities on subsequent filtration stages. The filter bag in the lower filter box further performs deep filtration of fine particles. This three-layer filtration system progressively reduces the impurity content entering the coolant tank, minimizing the problem of sludge buildup in the coolant tank from the source. This effectively reduces the need for frequent use of a sludge removal machine for the coolant tank, ensuring the convenience of using the coolant tank and effectively solving the problems in the background art.
[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:
[0006] A cooling fluid tank filtration and circulation structure for a CNC machine tool includes a cooling fluid tank with a recovery port fixedly connected to its top. The structure also includes a support frame, a vibration motor, a U-shaped support plate, and a filtration mechanism. The U-shaped support plate, which supports the filtration mechanism, is obstructed above the recovery port. A support frame for ground support is welded to the side of the U-shaped support plate extending beyond the cooling fluid tank. A vibration motor is installed below the top plate of the support frame. The filtration mechanism includes a frame... The system comprises a bottom filter box, a magnetic rod, a drawer filter box, a drawer frame, a filter bag pocket, and an L-shaped drawer plate. The drawer frame is fitted into the inner groove of the U-shaped support plate, and the bottom filter box is welded to the lower frame of the drawer frame. The bottom filter box passes through the drawer frame and the recovery port seat and enters the coolant tank. A magnetic rod is placed inside the bottom filter box. A drawer filter box with a side opening is welded to the bottom of the bottom filter box, and an L-shaped drawer plate is detachably connected to the side opening of the drawer filter box. A drawer frame containing a filter bag pocket is fixed to one side of the L-shaped drawer plate.
[0007] Furthermore, the top of the U-shaped tray is recessed with a U-shaped groove for mounting the frame, and the U-shaped groove of the U-shaped tray is provided with a fixed hole for inserting the fixed column, and the fixed column is fixed below the frame on the outside of the bottom filter box.
[0008] By adopting the above technical solution, the frame can be clamped in the U-shaped recessed groove of the U-shaped support plate, and then the fixed column is used to insert and position it in the fixed hole at this point, ensuring that the frame can be firmly placed on the U-shaped support plate.
[0009] Furthermore, the bottom filter box has filter holes on its bottom wall and four sides, and the bottom of the drawer filter box below the bottom filter box has filter holes for draining liquid.
[0010] By adopting the above technical solution, the bottom wall and four sides of the bottom filter box have filter holes that allow the liquid to be filtered out downwards, while the liquid discharged from the bottom of the bottom filter box can be discharged downwards through the filter holes of the drawer filter box.
[0011] Furthermore, U-shaped frames are symmetrically fitted inside the bottom filter boxes on both sides of the magnetic rod, and the opposing frame walls of the U-shaped frames are provided with insertion holes for inserting the magnetic rod.
[0012] By adopting the above technical solution, the magnetic plate can be inserted into the U-shaped frame to form a structure that magnetically attracts metal chips inside the bottom filter box, thereby intercepting and collecting some magnetically attracted metal chips.
[0013] Furthermore, the inner wall of the filter box has symmetrically protruding butt plates for supporting the drawer frame, and the surface of the butt plates has grooves for mounting the edge fixing blocks. The edge fixing blocks are symmetrically bonded to the lower frame wall of the drawer frame, and the inner frame groove wall of the drawer frame has recessed grooves for inserting filter bag pockets for bonding. The two sets of frame strips of the drawer frame are welded to the vertical plate surface of the L-shaped drawer panel. The outer plate surface of the L-shaped drawer panel has three sets of grooves with concave grooves. The two sets of edge grooves of the concave grooves have mounting holes for screw bolts between them and the filter box. A buckle strip protrudes from the central groove of the concave groove.
[0014] By adopting the above technical solution, after the edge of the filter bag is inserted into the groove of the drawer frame and bonded, the drawer frame is welded with an L-shaped drawer plate to form a replaceable bottom filter element. The drawer frame can be slid into the groove on the surface of the mating plate with the help of the rubber edge fixing block. At this time, the L-shaped drawer plate can block the side opening of the filter box. Then, bolts are screwed into the filter box from the two sets of edge grooves of the inner concave groove for locking and installation. After the bolts at the inner concave groove and the filter box are removed, the bottom filter element can be pulled out by fastening the buckle at the inner concave groove.
[0015] Furthermore, a T-shaped hook groove for mounting a T-shaped hook strip is provided below the top frame plate of the support frame, and the T-shaped hook strip is symmetrically welded to the surface of the seat plate of the vibrating motor. A bolt is screwed between the seat plate of the vibrating motor and the support frame. A perforated base plate with surface openings is integrally formed on one side of the bottom frame of the support frame.
[0016] By adopting the above technical solution, the T-shaped hook strip welded to the vibratory motor can be slidably locked into the T-shaped hook groove of the support frame for positioning and support. Then, bolts are screwed into the seat plate of the vibratory motor and the support frame to lock and prevent detachment, ensuring that the vibratory motor can stably provide vibration at the support frame.
[0017] Furthermore, a rubber gasket frame is bonded to the inner wall of the recycling port seat, and a bottom filter box extends through the rubber gasket frame.
[0018] By adopting the above technical solution, the recovery port seat is covered by a rubber pad frame on the outside of the bottom filter box, so that the bottom filter box will not directly contact the recovery port seat and cause friction damage when vibrating.
[0019] Compared with the prior art, the present invention has the following beneficial effects:
[0020] This invention features a support frame at the bottom of the coolant tank in a CNC machine tool for assembling a filtration mechanism. The bottom filter box of the filtration mechanism achieves preliminary filtration through filter holes on all four sides and at the bottom, intercepting most suspended impurities. The built-in magnetic rod is stably installed with the help of a U-shaped frame, accurately adsorbing ferromagnetic metal shavings in the coolant, reducing the burden of metal impurities on subsequent filtration stages. The filter bag in the lower filter box further performs deep filtration of fine particles. This three-layer filtration system progressively reduces the impurity content entering the coolant tank, reducing the problem of sludge accumulation in the coolant tank from the source, effectively reducing the need for frequent use of a sludge removal machine in the coolant tank, and ensuring the convenience of using the coolant tank.
[0021] Furthermore, the vibration motor is securely connected to the support frame via a T-shaped hook. During operation, it can drive the entire filtration mechanism to vibrate slightly, which can promptly shake off impurities adhering to the filter holes and magnetic rod surface of the bottom filter box, avoiding the decrease in filtration efficiency caused by filter hole blockage, ensuring smooth circulation of coolant, and further improving the stability and continuity of filtration.

[0028] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0029] like Figure 1-5 As shown, a cooling water tank filtration and circulation structure for a CNC machine tool includes a cooling water tank 1. A recovery port seat 2 is fixedly connected to the top of the cooling water tank 1. The structure also includes a support frame 4, a vibration motor 5, a U-shaped support plate 6, and a filtration mechanism 7. The U-shaped support plate 6, which supports the filtration mechanism 7, is obstructed above the recovery port seat 2. A support frame 4 for ground support is welded to the side of the U-shaped support plate 6 extending beyond the cooling water tank 1. The vibration motor 5 is installed below the top frame plate of the support frame 4. The filtration mechanism 7 includes a frame 8, a bottom filter box 10, and a magnetic rod 12. The system comprises a filter box 13, a drawer frame 15, a filter bag pocket 16, and an L-shaped drawer plate 17. The drawer frame 8 is fitted into the inner groove of the U-shaped support plate 6, and a bottom filter box 10 is welded to the lower frame of the drawer frame 8. The bottom filter box 10 passes through the drawer frame 8 and the recovery port seat 2 and enters the coolant tank 1. A magnetic rod 12 is placed inside the bottom filter box 10. A drawer box 13 with a side opening is welded to the bottom of the bottom filter box 10, and an L-shaped drawer plate 17 is detachably connected to the side opening of the drawer box 13. A drawer frame 15 containing a filter bag pocket 16 is fixed to one side of the L-shaped drawer plate 17.
[0030] The top of the U-shaped support plate 6 is recessed with a U-shaped groove for mounting the frame 8, and the U-shaped groove of the U-shaped support plate 6 is provided with a fixed hole for inserting the fixed column 9, and the fixed column 9 is fixed below the frame 8 on the outside of the bottom filter box 10.
[0031] By adopting the above technical solution, the frame 8 can be clamped in the U-shaped recessed groove of the U-shaped support plate 6, and then the fixed post 9 is used to insert and position it in the fixed hole at this location, so as to ensure that the frame 8 can be firmly placed on the U-shaped support plate 6.
[0032] The bottom filter box 10 has filter holes on its bottom wall and four sides, and the bottom of the drawer filter box 13 below the bottom filter box 10 has filter holes for draining liquid.
[0033] By adopting the above technical solution, the bottom wall and four sides of the bottom filter box 10 have filter holes that can drain the liquid downwards, and the liquid discharged from the bottom of the bottom filter box 10 can be discharged downwards from the filter holes of the drawer filter box 13.
[0034] Among them, U-shaped frames 11 are symmetrically installed in the bottom filter boxes 10 on both sides of the magnetic rod 12, and the opposing frame walls of the U-shaped frames 11 are provided with insertion holes for inserting the magnetic rod 12.
[0035] By adopting the above technical solution, after the magnetic plate 12 is inserted into the U-shaped frame 11, it can form a structure that magnetically attracts metal chips placed in the bottom filter box 10, thereby intercepting and collecting some magnetically attracted metal chips.
[0036] The inner wall of the filter box 13 has symmetrically protruding connecting plates 14 for supporting the drawer frame 15, and the surface of the connecting plates 14 has grooves for mounting the edge fixing blocks 19. The edge fixing blocks 19 are symmetrically bonded to the lower frame wall of the drawer frame 15, and the inner frame groove wall of the drawer frame 15 has recessed grooves for inserting and bonding the filter bag pocket 16. The two sets of frame strips of the drawer frame 15 are welded to the vertical plate surface of the L-shaped drawer plate 17. The outer plate surface of the L-shaped drawer plate 17 has three sets of grooves 18 arranged in a recessed manner, and the two sets of edge grooves of the recessed grooves 18 are provided with mounting holes for screw bolts between the filter box 13 and the two sets of edge grooves of the recessed grooves 18. A buckle strip protrudes from the central groove of the recessed grooves 18.
[0037] By adopting the above technical solution, after the edge of the filter bag pocket 16 is inserted into the groove of the drawer frame 15 and bonded, the drawer frame 15 is welded with an L-shaped drawer plate 17 to form a replaceable bottom filter element. The drawer frame 15 can be slid into the groove on the surface of the mating plate 14 with the help of the rubber side fixing block 19. At this time, the L-shaped drawer plate 17 can block the side opening of the filter box 13. Then, bolts are screwed into the filter box 13 from the two sets of edge grooves of the inner concave groove 18 for locking and installation. After the bolts at the inner concave groove 18 and the filter box 13 are removed, the bottom filter element can be pulled out by fastening the buckle at the inner concave groove 18.
[0038] The support frame 4 has a T-shaped hook groove for mounting the T-shaped hook strip 21 below the top frame plate, and the T-shaped hook strip 21 is symmetrically welded to the surface of the seat plate of the vibration motor 5. The seat plate of the vibration motor 5 is screwed to the support frame 4 with bolts. The bottom frame of the support frame 4 has a surface hole base plate 20 integrally formed on one side.
[0039] By adopting the above technical solution, the T-shaped hook strip 21 welded to the vibration motor 5 can be slidably locked in the T-shaped hook groove of the support frame 4 for positioning and support. Then, bolts are screwed into the seat plate of the vibration motor 5 and the support frame 4 to lock and prevent detachment, ensuring that the vibration motor 5 can stably provide vibration at the support frame 4.
[0040] Among them, a rubber pad frame 3 is bonded to the inner wall of the recycling port seat 2, and a bottom filter box 10 extends out of the rubber pad frame 3.
[0041] By adopting the above technical solution, the recovery port seat 2 is covered by a rubber pad frame 3 on the outside of the bottom filter box 10, so that the bottom filter box 10 will not directly contact the recovery port seat 2 and cause friction damage when vibrating.
[0042] It should be noted that this utility model is a filter circulation structure for a coolant tank of a CNC machine tool. A support frame 4 is set at the coolant tank 1 used at the bottom of the CNC machine tool to assemble the filter mechanism 7. The bottom filter component assembled from the drawer frame 15, filter bag 16 and L-shaped drawer plate 17 can be inserted into the side box opening of the drawer filter box 13 as a replaceable component. This allows the side fixing block 19 under the drawer frame 15 to be elastically deformable and locked in place at the mating plate 14 inside the drawer filter box 13. At this time, the L-shaped drawer plate 17 blocks the side box opening of the drawer filter box 13. Then, bolts are screwed into the drawer filter box 13 from the two sets of edge grooves of the inner recess groove 18 for locking and installation. After inserting the magnetic rod 12 between the U-shaped frame 11, it can be placed in the bottom filter box 10.
[0043] At this point, the surface plate 20 of the support frame 4 is placed on the ground on one side of the coolant tank 1, so that the U-shaped support plate 6 blocks the top of the recovery port seat 2. A weight can be placed on the surface plate 20 for counterweight. Then, the bottom filter box 10, carrying the drawer filter box 13, passes through the U-shaped support plate 6 and the rubber pad frame 3 and enters the coolant tank 1 along the recovery port seat 2, so that the lower half of the drawer filter box 13 enters the coolant in the coolant tank 1. At this time, the recovery port seat 2 can face the drain port of the CNC machine tool. When the cooling pump at the coolant tank 1 draws the coolant from the tank, it supplies the coolant to the CNC machine tool workpiece through the pipeline. When the machine tool is in use for cooling, the coolant inside the CNC machine tool, carrying a small amount of metal shavings, can flow downwards into the recovery port seat 2. The metal shavings in the coolant will be simply filtered at the bottom filter box 10, and some of the metal shavings will be collected in the bottom filter box 10 by the magnetic rod 12. At this time, a small amount of metal shavings will enter the drawer filter box 13 downwards through the filter holes at the bottom of the bottom filter box 10. After further filtration by the filter bag 16 in the drawer filter box 13, the relatively clean coolant will be discharged from the filter holes at the bottom of the drawer filter box 13 into the coolant tank 1 for circulation and supply to the CNC machine tool for processing and cooling, thus realizing the filtration and circulation of coolant.
[0044] After the CNC machine tool stops, the vibration motor 5 can be turned on for 1-2 minutes to shake the metal shavings in the bottom filter box 10 apart, ensuring that the bottom filter box 10 can continuously filter and collect metal shavings. When there are a lot of metal shavings in the bottom filter box 10, the external coolant tank 1 can be pulled out a distance. Then, the filter mechanism 7 can be lifted up by fastening it to the frame 8 to pour out the metal shavings collected in the bottom filter box 10. The magnetic rod 12 can be removed to clean the magnetically attracted metal shavings. At the same time, the bolts between the L-shaped drawer plate 17 and the drawer filter box 13 can be unscrewed and fastened to the buckle of the inner recessed groove 18. The bottom filter can be pulled out for direct replacement, or the filter bag 16 can be manually cleaned. After cleaning, the filter mechanism 7 can be reinstalled according to the above steps. The vibration motor 5 can be connected to an external controller for power control under the guidance of the manufacturer's electrical technicians.
[0045] It should be noted that this utility model is a filter circulation structure for a coolant tank of a CNC machine tool. All components in this utility model are known to those skilled in the art, and their structure and principle can be learned by those skilled in the art through technical manuals or conventional experimental methods.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
