Abstract
Description
Technical Field
[0001] This utility model relates to the field of CNC machine tool cleaning technology, and specifically to a cleaning device for CNC machine tools. Background Technology
[0002] During CNC machine tool processing, a large amount of waste such as iron filings and iron powder of various shapes are generated. If these wastes accumulate at the bottom of the machine tool for a long time, they will not only affect the normal operation of the machine tool, but may also have an adverse effect on machining accuracy and product quality. Therefore, they need to be collected and cleaned regularly.
[0003] Currently, traditional cleaning methods mainly employ water-based flushing systems. These systems inject clean water into the CNC machine tool, using the flushing action of the water flow to mix iron filings and iron powder, forming a solid-liquid two-phase flow. The mixture is then pumped to cleaning equipment. Inside the equipment, a filtration system intercepts the iron filings and iron powder, achieving solid-liquid separation. Finally, the intercepted solid waste is discharged for centralized treatment.
[0004] However, this traditional cleaning method has significant technical bottlenecks. First, the physical properties of iron filings make them prone to forming a filter cake layer on the surface of the filter mechanism, causing blockage. This necessitates disassembly and cleaning, which is time-consuming and labor-intensive. Second, due to the limited pore size of the filter mechanism, some extremely small iron particles cannot be effectively intercepted and require secondary treatment after being discharged with the water flow. These two problems combined greatly reduce the efficiency of cleaning CNC machine tool waste. Utility Model Content
[0005] In view of the above-mentioned technical deficiencies, the purpose of this utility model is to provide a cleaning device for CNC machine tools, so as to solve the problem of reduced cleaning efficiency caused by iron filings clogging the filter mechanism and the inability to effectively intercept fine iron powder in the existing technology.
[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: The present invention provides a cleaning device for CNC machine tools, comprising: a housing, the housing having a first filter chamber, a second filter chamber and a collection chamber that are interconnected, a filter cylinder being rotatably disposed in the first filter chamber, and a filter screen being fixed in the second filter chamber; wherein, a filter plate that can move within the filter cylinder is disposed in the filter cylinder, and a plurality of magnetic components are fixed on the filter screen.
[0007] Optionally, the filter plate has brushes distributed along its outer periphery, the brushes being attached to the inner wall surface of the filter cartridge, the brushes scraping the inner wall surface of the filter cartridge as they move with the filter plate.
[0008] Optionally, a central shaft is fixed inside the filter cartridge, the filter plate is sleeved on the central shaft, a pull cylinder is also fixed on the filter plate, the pull cylinder is also sleeved on the central shaft, and a handle is provided inside the pull cylinder.
[0009] Optionally, the housing is rotatably provided with a door for use with the filter cartridge, the door is provided with a feed pipe, the feed pipe is connected to the interior of the filter cartridge, and the collection chamber is connected with a discharge pipe.
[0010] Optionally, it also includes a suction device and a discharge device, the suction device having a feed port connected to the feed pipe, and the discharge device also having a feed port connected to the discharge pipe.
[0011] Optionally, the second filter cavity has a first inclined surface.
[0012] Optionally, the filter screen has a second inclined surface on the side facing the filter cartridge.
[0013] Optionally, a protrusion is provided on the side of the box door facing the filter cartridge, and the protrusion is used in conjunction with the handle.
[0014] Optionally, the bump is made of a flexible material.
[0015] Optionally, the central shaft passes through the filter cartridge and the housing, and extends to the outside of the housing, and the central shaft is driven to rotate by a motor.
[0016] The beneficial effects of this utility model are as follows:
[0017] The filter cartridge of this invention can rotate inside the first filter chamber, and the iron filings on the filter screen are peeled off by gravity and centrifugal force, causing them to tumble inside the filter cartridge, reducing the contact time with the inner wall of the filter cartridge, thereby reducing accumulation and relieving clogging.
[0018] Meanwhile, this invention features a filter plate with a brush inside the filter cartridge. The filter plate has a pull cylinder with a handle. When the filter cartridge is full of iron filings, pulling the pull cylinder moves the filter plate inside the cartridge, pushing out the iron filings without disassembling the cartridge, thus improving cleaning efficiency. The brush also scrapes the inner wall of the filter cartridge as it moves with the filter plate, reducing residue.
[0019] In addition, this invention also incorporates a magnetic component on the filter screen. This magnetic component can adsorb the wastewater passing through the filter cartridge and extract any iron powder that escapes from it, thus preventing it from falling into the collection chamber and requiring further processing.
[0020] The combination of the above three points greatly improves the efficiency of this equipment in cleaning up waste such as iron filings and iron powder from CNC machine tools. Attached Figure Description

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0032] As mentioned earlier, traditional cleaning methods have significant technical bottlenecks. First, the physical properties of iron filings make them prone to forming a filter cake layer on the surface of the filter mechanism, causing blockage. This necessitates disassembly and cleaning, which is time-consuming and labor-intensive. Second, due to the limited pore size of the filter mechanism, some extremely small iron particles cannot be effectively intercepted and require secondary treatment after being discharged with the water flow. These two problems combined greatly reduce the efficiency of cleaning CNC machine tool waste.
[0033] To address this issue, the present invention provides a cleaning device that solves the problem of the large amount of waste generated during the daily processing of CNC machine tools. The present invention solves this problem in the following way.
[0034] Example 1:
[0035] Please refer to the instruction manual appendix. Figures 1 to 7 As shown in the figure, this embodiment provides a cleaning device for CNC machine tools. The device includes a housing 1, a filter cartridge 2, and a filter screen 4. The housing 1 has a first filter chamber 12, a second filter chamber 13, and a collection chamber 14 that are interconnected. The first filter chamber 12, the second filter chamber 13, and the collection chamber 14 are arranged sequentially from top to bottom. A door 11 is opened on the side of the first filter chamber 12. The door 11 is hinged to the housing 1 and fixed by a latch.
[0036] In this first embodiment, as Figure 3 As shown, the filter cartridge 2 is horizontally disposed inside the first filter chamber 12, with an opening on the side near the door 11. The portion of the housing 1 located in the first filter chamber 12 has an extending boss, to which the filter cartridge 2 is rotatably connected (e.g., a slewing bearing or slewing support). A central shaft 21 is fixed inside the filter cartridge 2, passing through the filter cartridge 2 and the housing 1, and extending to the outside of the housing 1. A pulley is fixed to the central shaft 21, and a pulley is also fixed to the motor. These two pulleys are connected by a belt (a sprocket or chain may also be used). Therefore, when the motor is powered on, it can drive the central shaft 21 to rotate, thereby causing the filter cartridge 2 to rotate within the housing 1.
[0037] In this first embodiment, as Figures 1 to 3 As shown, the door 11 is equipped with a feed pipe 15. One end of the feed pipe 15 is connected to the feed port of a suction device (e.g., a water pump with a water pipe), and the other end is connected to the filter cylinder 2. When the suction device pumps the mixture of iron filings and water from the CNC lathe into the filter cylinder 2, the water passes through the filter holes of the filter cylinder 2, while the iron filings are trapped inside the filter cylinder 2. As the iron filings rotate inside the filter cylinder 2, they continuously tumble, thereby reducing the contact time with the inner wall of the filter cylinder 2 and making them less likely to adhere to the cylinder wall.
[0038] Example 2:
[0039] Based on the above embodiments, in order to further clarify and completely explain the technical solutions therein, this utility model also provides an embodiment two. For example... Figures 1 to 7 As shown, in this second embodiment, a filter plate 3 is disposed inside the filter cartridge 2, and the filter plate 3 is sleeved on the central shaft 21. A pull cylinder 32 is also fixed on the filter plate 3. The pull cylinder 32 is also sleeved on the central shaft 21, and the length of the pull cylinder 32 is longer than the length of the central shaft 21. A handle 33 is disposed inside the part of the cylinder that extends beyond the central shaft 21. A protrusion 111 is disposed on the side of the door 11 facing the filter cartridge 2, and the protrusion 111 is used in conjunction with the handle 33. The protrusion 111 is made of a flexible material (e.g., silicone).
[0040] Therefore, when the door 11 is closed, the protrusion 111 is inserted into the space between the handle 33 and the pull cylinder 32, causing the filter cylinder 2 and the central shaft 21 to rotate. The pull cylinder 32 and the filter plate 3 remain stationary due to the influence of the protrusion 111. When the filter cylinder 2 is full of iron filings and needs cleaning, the door 11 is opened, the protrusion 111 and the pull cylinder 32 disengage, exposing the handle 33. At this time, the operator pulls the handle 33 and pulls it outward, which moves the filter plate 3, thereby pulling out the iron filings accumulated in the filter cylinder 2. The iron filings fall through the door 11 into the collection component (e.g., the collection frame) for further processing. The filter plate 3 has brushes 31 distributed along its outer periphery, which adhere to the inner wall surface of the filter cylinder 2. Therefore, when the filter plate 3 moves inside the filter cylinder 2, the brushes 31 follow the movement of the filter plate 3 and scrape the inner wall surface of the filter cylinder 2, reducing residual iron filings and achieving efficient cleaning.
[0041] Example 3:
[0042] Based on the above embodiments, in order to further clarify and completely explain the technical solutions therein, this utility model also provides an embodiment three. For example... Figures 3 to 4 As shown, in this third embodiment, after the mixture of iron filings and water passes through the filter cylinder 2, most of the iron filings are filtered out, while a small portion of iron powder passes through the first filter chamber 12 and enters the second filter chamber 13, which has a first inclined surface 131. The mixture falls onto the first inclined surface 131, is guided and accelerated through, and falls onto the filter screen 4, which has a second inclined surface 41 on the side facing the filter cylinder 2. The second inclined surface 41 is convex in the middle and low on both sides. When the mixture falls on it, it is guided to flow from the middle to both sides, increasing the flow area of the mixture. Several magnetic elements 5 are fixed on the filter screen 4. When the mixture falls onto the filter screen 4 and the magnetic elements 5 (e.g., magnetic rods), the fine iron powder in the mixture is attracted by the magnetic elements 5 and thus collected. Finally, only water without iron filings and iron powder enters the collection chamber 14 and is discharged by the discharge mechanism (e.g., water pump) connected to the discharge pipe 16.
[0043] Therefore, in summary, this utility model and its embodiments, compared with the prior art, have the following advantages, including but not limited to:
[0044] The filter cartridge 2 of this invention can rotate inside the first filter chamber 12. It can peel off the iron filings on the filter screen 4 by gravity, centrifugal force, etc., and make them roll inside the filter cartridge 2, thereby reducing the contact time with the inner wall of the filter cartridge 2, thus reducing accumulation and relieving clogging.
[0045] Meanwhile, this invention includes a filter plate 3 with a brush 31 inside the filter cartridge 2. The filter plate 3 has a pull cylinder 32 with a handle 33. When the filter cartridge 2 is full of iron filings, pulling the pull cylinder 32 will move the filter plate 3 inside the filter cartridge 2, thereby pushing out the iron filings without disassembling the filter cartridge 2, thus improving cleaning efficiency. The brush 31 also scrapes the inner wall of the filter cartridge 2 as it moves with the filter plate 3, reducing residue.
[0046] In addition, this utility model also provides a magnetic component 5 on the filter screen 4. The magnetic component 5 can adsorb the sewage passing through the filter cartridge 2 and extract the iron powder that escapes inside, avoiding the trouble of it falling into the collection chamber 14 and needing to be processed again.
[0047] The combination of the above three points greatly improves the efficiency of this equipment in cleaning up waste such as iron filings and iron powder from CNC machine tools.
[0048] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of this utility model and its equivalents, this utility model also intends to include these modifications and variations.
