Description

Technical Field

[0001] This utility model relates to the field of CNC machine tool technology, specifically to a chip removal device for machine tool water tanks. Background Technology

[0002] During the cutting process, cutting fluid reduces friction between the rake face and the chip, and between the flank face and the machined surface, forming a partial lubricating film. This reduces cutting force, friction, and power consumption, lowers the surface temperature and tool wear at the friction points between the tool and the workpiece, and improves the machinability of the workpiece material. However, a large amount of metal filings, impurities, and other debris generated during machining will mix into the cutting fluid. To ensure the cleanliness of the cutting fluid and maintain the normal operation and machining accuracy of the machine tool, it is necessary to filter the cutting fluid through a filtration system to separate the metal filings and impurities.

[0003] For example, Chinese utility model patent CN220029530U provides a chip removal device for a machine tool water tank, including a water tank and an adsorption filter device for treating cutting fluid inside the water tank. This device can adsorb and remove suspended metal chips in the cutting fluid, enabling more thorough collection and cleaning of tiny debris in the cutting fluid, thereby ensuring the quality of products processed by the machine tool. When a certain amount of metal chips are collected in the adsorption filter device, the metal chips are wrapped and transferred using plastic sheeting, thus cleaning the adsorption filter device in the same way.

[0004] However, existing chip removal equipment has a relatively simple filtration structure, which is prone to clogging due to excessive chip accumulation during the chip removal process using cutting fluid. Once clogged, this not only reduces chip removal efficiency and affects the circulation of cutting fluid, but also interferes with the normal operation of the machine tool. To ensure the normal operation of the chip removal equipment, operators need to frequently clean the filtration structure. This frequent cleaning significantly increases the workload of operators, reduces production efficiency, and also raises equipment maintenance costs. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model proposes a machine tool water tank chip removal device to solve the technical problem mentioned in the background art: in the process of removing chips from cutting fluid, the filter structure of the existing machine tool water tank chip removal device is prone to clogging due to excessive accumulation of iron chips, requiring frequent cleaning of the filter structure and increasing the labor burden of the workers.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a chip removal device for a machine tool water tank.

[0007] Including:

[0008] The housing is equipped with a connected inlet and outlet pipe;

[0009] The mounting bracket is detachably installed inside the housing, and the mounting bracket has a rotatable annular frame inside.

[0010] An impeller is fixedly installed within the annular frame, and the water outlet direction of the inlet pipe faces the blades of the impeller; and

[0011] The filter screen is provided in multiple sets and is detachably disposed around the periphery of the annular frame.

[0012] In a preferred embodiment, the box body has a cover on the open side, a first support ring is provided on the inner wall of the box body, a second support ring is provided on the cover, and the two ends of the mounting bracket are respectively mounted in the first support ring and the second support ring.

[0013] In a preferred embodiment, a screw-on sealing plate is provided on one side of the cover, and the sealing plate abuts against the end of the mounting bracket.

[0014] In a preferred embodiment, a first sealing gasket is provided inside the first support ring on the inner side of the box, and a second sealing gasket is provided at one end of the sealing plate. The first sealing gasket and the second sealing gasket abut against both ends of the mounting bracket, respectively.

[0015] In a preferred embodiment, the mounting bracket has retaining rings at both ends on its inner side, and the filter screen is disposed between the two sets of retaining rings.

[0016] In a preferred embodiment, the two ends of the annular frame are circumferentially spaced with balls, and the two ends of the inner side of the mounting bracket are provided with support rings. The annular frame is rotatably disposed within the support rings, and the balls abut against the inner side of the support rings.

[0017] In a preferred embodiment, the annular frame is provided with multiple sets of buckles, the filter screen is arc-shaped and has slots at both ends, and the buckles are engaged in the slots from the inside to the outside.

[0019] In a preferred embodiment, the impeller has a hollow structure.

[0020] In a preferred embodiment, a transparent observation window is also provided on one side of the enclosure.

[0021] Compared with the prior art, the present invention has the following beneficial effects:

[0022] When in use, the equipment connects its inlet pipe to the discharge end of the CNC machine tool's cutting fluid and its drain pipe to the cutting fluid recovery end. Used cutting fluid enters the tank through the inlet pipe and exits through the drain pipe. As the fluid enters the tank, it impacts the impeller blades, causing the impeller and annular frame to rotate, which in turn rotates multiple sets of filter screens. These screens filter iron filings from the cutting fluid. The rotating filter screens increase the effective filtration area, preventing clogging that can easily occur with filtration in a single location. The movement of the iron filings within the annular frame also reduces the frequency of clogging. When the iron filings accumulate to a certain level, the mounting bracket can be removed for quick cleaning, effectively reducing the frequency of cleaning by operators, improving the machining efficiency of the CNC machine tool, and reducing the workload of the operators.

[0030] The present invention will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present invention and should not be construed as limiting the scope of protection of the present invention. Those skilled in the art can make some non-essential improvements and adjustments to the present invention based on the above application content.

[0031] Example:

[0032] like Figure 1 , 2 As shown, this utility model provides a machine tool water tank chip removal device, including a box body 1, with an inlet pipe 2 and a drain pipe 5 connected to the box body 1. A mounting frame 11 is detachably installed inside the box body 1, and an annular frame 14 is rotatably installed inside the mounting frame 11. An impeller 18 is fixedly installed inside the annular frame 14. The water outlet direction of the inlet pipe 2 is towards the blades of the impeller 18. Multiple sets of filter screens 19 are detachably installed on the periphery of the annular frame 14.

[0033] In operation, the inlet pipe 2 is connected to the cutting fluid discharge end of the CNC machine tool, and the drain pipe 5 is connected to the subsequent storage and circulation equipment. When the liquid is discharged into the housing 1 through the inlet pipe 2, it can be filtered by the filter screen 19 to remove iron filings and impurities. When the liquid impacts the blades of the impeller 18, the impeller 18 drives the annular frame 14 to move, which in turn drives the filter screen 19 to move as a whole, increasing the effective filtration area and improving the filtration effect. Traditional filter structures have a single filtration position and a small filtration area. Compared with the traditional static filter structure, this equipment has a better filtration effect and is less prone to clogging. In addition, a transparent observation window 4 is provided on one side of the housing 1, which can be used to observe the filtration status of iron filings and impurities inside, facilitating timely cleaning.

[0034] like Figure 3 , 4 As shown, in this embodiment, a cover 7 is provided on the opening side of the box 1, a first supporting ring 3 is provided on the inner wall of the box 1, and a second supporting ring 8 is provided on the cover 7. The two ends of the mounting bracket 11 are respectively mounted in the first supporting ring 3 and the second supporting ring 8. The first supporting ring 3 and the second supporting ring 8 support the two ends of the mounting bracket 11. A screw-on sealing plate 9 is provided on one side of the cover 7. The sealing plate 9 abuts against the end of the mounting bracket 11. The sealing plate 9 blocks the opening of the box 1 to prevent liquid from flowing out of the box 1. At the same time, the sealing plate 9 can be used to fix the mounting bracket 11. After the sealing plate 9 is removed, the mounting bracket 11 can be disassembled for easy cleaning of impurities.

[0035] like Figure 3As shown, in this embodiment, a first sealing gasket 6 is provided inside the first supporting ring 3 on the inner side of the housing 1, and a second sealing gasket 10 is provided at one end of the sealing plate 9. The first sealing gasket 6 and the second sealing gasket 10 respectively abut against both ends of the mounting frame 11 to effectively prevent liquid from flowing from both ends of the mounting frame 11 to the bottom of the housing 1 and discharge, thereby improving the filtration effect. Furthermore, retaining rings 13 are provided at both ends of the inner side of the mounting frame 11, and the filter screen 19 is positioned between the two sets of retaining rings 13. The arrangement of the retaining rings 13 prevents the shavings obtained from filtration from falling out of the mounting frame 11 when it is disassembled, thus avoiding the need for cleaning the inside of the housing 1.

[0036] like Figure 4 As shown, in this embodiment, ball bearings 15 are arranged circumferentially at intervals at both ends of the annular frame 14, and support rings 12 are provided at both ends of the inner side of the mounting bracket 11. The annular frame 14 is rotatably disposed within the support rings 12, and the ball bearings 15 abut against the inner side of the support rings 12. The arrangement of the ball bearings 15 reduces the frictional force experienced by the annular frame 14 during rotation, and the impeller 18 has a hollow structure to reduce the overall weight of the rotating part and improve the rotation efficiency.

[0037] like Figure 4 As shown, in this embodiment, the annular frame 14 is provided with multiple sets of buckles 17. The filter screen 19 is arc-shaped with slots 20 at both ends. The buckles 17 are engaged in the slots 20 from the inside out. The filter screen 19 is installed by the cooperation of the buckles 17 and the slots 20, and it is also convenient to replace the filter screen 19 when it is worn out. The annular frame 14 is provided with an anti-detachment plate 16, which abuts against the outside of the filter screen 19. The anti-detachment plate 16 blocks the outside of the filter screen 19, and together with the buckles 17, it can fix the two sides of the filter screen 19, effectively preventing the filter screen 19 from detaching from the annular frame 14 due to deformation during the filtration process.

[0038] The specific usage and beneficial effects of this utility model are as follows:

[0039] When in use, the equipment connects its inlet pipe 2 to the discharge end of the CNC machine tool's cutting fluid, and its drain pipe 5 to the cutting fluid recovery end. After use, the cutting fluid can enter the tank 1 through the inlet pipe 2 and be discharged outside through the drain pipe 5. During the process of the liquid entering the tank 1, it applies an impact force to the blades of the impeller 18, causing the impeller 18 and the annular frame 14 to rotate, thereby driving multiple sets of filter screens 19 to rotate. The filter screens 19 filter the iron filings in the cutting fluid. At the same time, the rotating filter screens 19 can increase the effective filtration area and avoid clogging caused by filtration in a single location. At the same time, the iron filings in the annular frame 14 are in a moving state, reducing the frequency of clogging. When the iron filings in the annular frame 14 accumulate to a certain extent, the mounting bracket 11 can be removed to quickly clean the iron filings inside, effectively reducing the cleaning frequency of the workers, improving the processing efficiency of the CNC machine tool, and reducing the labor burden of the workers.

[0040] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. It will be apparent to those skilled in the art that this utility model is not limited to the details of the exemplary embodiments described above. Modifications or improvements can be made to this utility model, which is obvious to those skilled in the art. Therefore, all such modifications or improvements made without departing from the spirit of this utility model fall within the scope of protection claimed by this utility model.
