Abstract
Description
Technical Field
[0001] This utility model relates to the field of CNC engraving and milling machine technology, and in particular to a water flushing device for CNC engraving and milling machines. Background Technology
[0002] In the field of CNC milling and engraving machines, with the continuous improvement of industrial manufacturing precision and efficiency requirements, the importance attached to equipment operation stability and processing environment is increasing.
[0003] In traditional CNC milling machine operations, the milling head generates a large amount of heat due to intense friction with the workpiece during high-speed rotation. If not cooled in time, the milling head is prone to wear and deformation, which not only reduces its service life but also seriously affects machining accuracy, leading to a decline in product quality. Simultaneously, the milling process generates a large amount of iron dust. If this dust is allowed to disperse freely in the workshop, it will harm the health of operators, potentially causing respiratory diseases with long-term inhalation. Furthermore, the dust will enter other precision components of the equipment, accelerating wear and tear, increasing the likelihood of equipment failure, and affecting the continuity and stability of production. Utility Model Content
[0004] The purpose of this invention is to provide a water flushing device for CNC engraving and milling machines to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution, which includes a cooling and dust prevention component installed on the spindle housing, a water supply component installed inside the main body of the CNC engraving and milling machine, the output end of the water supply component being connected to the cooling and dust prevention component, the input end of the water supply component being connected to the liquid storage tank, a water inlet being installed on the top of the liquid storage tank, a recovery pipe being installed on one side of the liquid storage tank, and a filter component being installed on the top of the recovery pipe.
[0006] As a preferred embodiment of this utility model, the cooling and dustproof component is sleeved on the water supply plate one outside the spindle housing. The bottom of the water supply plate one is provided with several water spray nozzles, all of which are aligned with the milling head. The top of the water supply plate one is provided with a water supply plate two, and the outer wall of the water supply plate two is provided with several atomizing nozzles.
[0007] As a preferred embodiment of this utility model, the water supply component includes a double-layer frame disposed within the main body of the CNC engraving and milling machine. Pump body one and pump body two are disposed within the double-layer frame. The input ends of pump body one and pump body two are both disposed within a liquid storage tank. A hose one is disposed on the output end of pump body one, and the other end of hose one is disposed on a water delivery tray one. A hose two is disposed on the output end of pump body two, and the other end of hose two is disposed on a water delivery tray two.
[0008] As a preferred embodiment of this utility model, the filter assembly includes a recovery hopper, an annular electromagnetic plate at the bottom of the recovery hopper, a casing at the bottom outlet of the recovery hopper, a sealing ring on the inner wall of the casing, the casing being fitted onto the top of the recovery pipe, and several slots on the inner wall of the recovery hopper, each slot containing a rod, with a first filter screen and a second filter screen positioned between the rods, the first filter screen being located above the second filter screen.
[0009] As a preferred embodiment of this utility model, the first filter screen is a 250-mesh filter screen, and the second filter screen is a 500-mesh filter screen.
[0010] Compared with the prior art, the above-mentioned technical solution of this utility model has the following beneficial technical effects:
[0011] This invention features a water delivery tray mounted outside the spindle housing, with a bottom water nozzle precisely aligned with the milling head. During milling operations, the pump body delivers water from the storage tank to the water delivery tray via a hose, which is then sprayed out at high speed from the water nozzle. This quickly removes the large amount of heat generated by the milling head's high-speed rotation and friction with the workpiece, effectively preventing the milling head from overheating and causing increased wear and decreased precision. This extends the lifespan of the milling head, ensures machining accuracy, and allows the CNC milling machine to operate stably for extended periods.
[0012] This utility model uses a water delivery tray 2 set on top of a water delivery tray 1, with an atomizing nozzle surrounding the outer wall. The pump body 2 delivers water to the water delivery tray 2 through a hose 2, and a fine water mist is sprayed out from the atomizing nozzle. The iron dust generated by milling is absorbed by the water mist, preventing it from drifting in the workshop, improving the working environment, reducing the health risk of workers inhaling dust, reducing the corrosion of other parts of the equipment by dust, and reducing the equipment failure rate.
[0013] This invention achieves water resource recycling through the coordinated use of a liquid storage tank, a water supply component, and a filtration component. The water supply component draws water from the liquid storage tank to supply the cooling and dust prevention component. After use, the liquid flows into the filtration component through a return channel. The first filter screen (250 mesh) and the second filter screen (500 mesh) in the recovery hopper filter the water in sequence to remove impurities of various sizes. The filtered water returns to the liquid storage tank from the outlet of the recovery hopper through a recovery pipe, reducing water waste and lowering production costs.
[0014] This invention generates a magnetic field through the annular electromagnetic plate at the bottom of the recycling hopper, which adsorbs residual magnetic impurities onto the inner wall of the bottom of the recycling hopper, further improving the cleanliness of the liquid returning to the storage tank, ensuring the purity of the water delivered by the water supply components, avoiding wear or blockage of the pump body and water pipeline caused by impurities, and ensuring the stable and efficient operation of the entire flushing device.

Detailed Implementation
[0025] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this utility model. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of this utility model.
[0026] like Figures 1-9As shown, this utility model proposes a water flushing device for a CNC engraving and milling machine. It mainly consists of a cooling and dust prevention component 1, a water supply component 2, a liquid storage tank 3, and a filter component 4. The cooling and dust prevention component 1 is installed on the spindle housing 5 and is used to cool the milling head and absorb iron dust generated during the engraving and milling process. The water supply component 2 is installed inside the CNC engraving and milling machine body, with its input end connected to the liquid storage tank 3 and its output end connected to the cooling and dust prevention component 1, responsible for providing water to the cooling and dust prevention component 1. The liquid storage tank 3 has a water inlet 30 at the top for replenishing water, and a recovery pipe 31 on one side for recovering used liquid. The filter component 4 is installed at the top of the recovery pipe 31 to filter the recovered liquid.
[0027] The cooling and dust prevention component 1 mainly includes a water supply plate 10 and a water supply plate 2 12. The water supply plate 10 is sleeved on the outside of the spindle housing 5, and several water spray nozzles 11 are evenly distributed on its bottom. The positions of these water spray nozzles 11 are designed to be accurately aligned with the milling head so that the milling head can be directly rinsed and cooled during operation. The top of the water supply plate 10 is equipped with the water supply plate 2 12, and several atomizing nozzles 13 are arranged around the outer wall of the water supply plate 2 12 to spray out fine water mist and adsorb iron dust.
[0028] The water supply assembly 2 is installed on the double-layer frame 20 inside the main body of the CNC engraving and milling machine. The double-layer frame 20 provides stable installation support for pump body 1 21 and pump body 22. The input ends of pump body 1 21 and pump body 22 are extended into the liquid storage tank 3 through pipes to draw water from the liquid storage tank 3. The output end of pump body 1 21 is connected to hose 1 23, and the other end of hose 1 23 is connected to water delivery tray 10, so as to transport the water drawn by pump body 1 21 to water delivery tray 10. The output end of pump body 22 is connected to hose 2 24, and the other end of hose 2 24 is connected to water delivery tray 2 12, so as to transport the water drawn by pump body 22 to water delivery tray 2 12. Through this connection method, the water supply assembly 2 can stably supply water to the cooling and dust prevention assembly 1.
[0029] The filter assembly 4 mainly consists of a recovery hopper 40. A ring-shaped electromagnetic plate 46 is installed at the bottom of the recovery hopper 40 to adsorb magnetic impurities that remain after filtration. A sleeve 41 is provided at the water outlet at the bottom of the recovery hopper 40. A sealing ring is installed on the inner wall of the sleeve 41. The sleeve 41 is tightly fitted onto the top of the recovery pipe 31 to ensure that the recovered liquid does not leak when flowing into the recovery pipe 31. Several slots 42 are opened on the inner wall of the recovery hopper 40. A rod 43 is inserted into each slot 42. A first filter screen 44 and a second filter screen 45 are installed through the rod 43. The first filter screen 44 is located above the second filter screen 45. The first filter screen 44 is a 250-mesh filter screen, which is mainly used to intercept larger particles of impurities. The second filter screen 45 is a 500-mesh filter screen, which can further filter out smaller particles of impurities, thereby realizing two-stage filtration of the recovered liquid.
[0030] During the operation of the CNC milling machine, the working principle of this device is as follows: When the flushing device needs to be turned on, pump body 1 21 and pump body 2 22 are started at the same time. These two pump bodies use the liquid storage tank 3 as the water source and use their own pumping capacity to draw water out of the liquid storage tank 3. Among them, pump body 1 21 delivers water through hose 1 23, and pump body 2 22 delivers water through hose 2 24. The two water flows are delivered to water delivery pan 1 10 and water delivery pan 2 12 respectively.
[0031] Water inside the water supply tray 10 is powerfully sprayed out from several water nozzles 11, directly hitting the milling head. During the operation of the engraving and milling machine, the milling head rotates at high speed and generates a lot of heat due to friction with the workpiece. These high-speed water jets can effectively remove the heat from the milling head, achieving flushing and cooling of the milling head. Water inside the water supply tray 2 12 is also sprayed out from several atomizing nozzles 13, forming a fine water mist. During the engraving and milling process, iron dust is generated. This water mist can fully contact and adsorb the iron dust, thereby preventing the iron dust from drifting in the processing environment, which not only protects the health of the operators but also maintains the cleanliness of the processing environment.
[0032] After completing tasks such as flushing and adsorbing iron dust, the liquid containing impurities flows along the return trough and is poured into the filter assembly 4. The filter assembly 4 is equipped with a first filter screen 44 and a second filter screen 45. They filter the impurities mixed in the liquid in sequence according to different filtration precisions. Larger particles of impurities are first intercepted by the first filter screen 44, while smaller particles of impurities are further filtered by the second filter screen 45. After two stages of filtration, the relatively clean liquid finally flows back to the storage tank 3 from the outlet of the recovery hopper 40, realizing the recycling of water resources.
[0033] Even after filtration by the first filter screen 44 and the second filter screen 45, some fine magnetic impurities may still remain in the liquid. At this time, the annular electromagnetic plate 46 comes into play. It generates a strong magnetic field that attracts these residual magnetic impurities, causing them to be adsorbed onto the inner wall of the bottom of the recovery hopper 40. This further ensures the cleanliness of the liquid returning to the storage tank 3 and ensures the continuous, stable operation and efficient work of the entire flushing device.
