Description

Technical Field

[0001] This utility model relates to the field of mechanical processing equipment technology, and in particular to a spraying device for a vertical machining center. Background Technology

[0002] The spray system of a vertical machining center effectively reduces the temperature during machining by spraying coolant onto the machining area, preventing parts from deforming due to high temperatures, while also improving tool durability and machining accuracy. However, existing spray systems have significant problems in terms of coolant recycling.

[0003] Coolant carries a large amount of fine metal powder and impurities generated during cutting. These impurities gradually deposit during the coolant's circulation process, forming sludge that can clog spray pipes, affecting the smooth flow of coolant and the spraying effect. In addition, the accumulation of sludge can also cause coolant to deteriorate, reducing its cooling and lubrication performance, and even damaging processing equipment and parts.

[0004] To address the aforementioned issues, existing technologies typically employ simple filtration devices to purify the coolant; however, this filtration method is often ineffective, and the problem of sludge clogging the pipes remains prominent. Therefore, there is an urgent need for a new type of spray device for vertical machining centers. Utility Model Content

The upper end of the sedimentation tank is fixedly connected to the top of the water tank, and an overflow hole is provided along the upper edge of the sedimentation tank. The online cleaning mechanism includes a cleaning frame and a sludge collection box. A drive wheel and a tensioning seat are located within the cleaning frame. A driven wheel is located at the lower end of the tensioning seat. A porous adsorption belt is provided on the drive wheel and the driven wheel. A motor and a scraper are located on the outer side of the cleaning frame. The output shaft of the motor is connected to the drive wheel.

[0007] Furthermore, the sludge receiving box is equipped with an overflow pipe and a sludge receiving plate. The lower end of the overflow pipe is connected to the sedimentation tank. The sludge receiving plate is equipped with hooks that cooperate with the side wall of the sludge receiving box. The upper end of the hooks is equipped with a handle. The connecting seats on both sides of the sludge receiving box are equipped with strip-shaped sliding holes. The bolts on the water tank frame pass through the strip-shaped sliding holes to restrict the sludge receiving box thereon.

[0020] 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 the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0021] Reference Figure 1 , Figure 2 This utility model provides a spraying device for a vertical machining center, including a water tank frame 1 and spraying pipes (not shown in the figure). The water tank frame 1 is equipped with a spray pump 4, a liquid level detection mechanism 3, a return water filtration mechanism 5, and an online cleaning mechanism 6. A water tank 2 is installed inside the water tank frame 1. The water inlet end of the spray pump 4 and the detection end of the liquid level detection mechanism 3 are both located inside the water tank 2. The water tank 2 is used to store coolant. The spray pump 4 sprays the coolant to the machining area through the spraying pipes. A heating pipe 7 is also installed on the water tank frame 1. The lower end of the heating pipe 7 is located inside the water tank 2. In cold environments, the heating pipe 7 can heat the coolant to prevent it from freezing and affecting its use. A drain pipe 201 is installed at the bottom of the water tank 2 for discharging waste liquid in the water tank 2 for thorough cleaning.

[0022] A sedimentation tank 202 is installed in the water tank 2 below the return water filtration mechanism 5 and the online cleaning mechanism 6. The upper end of the sedimentation tank 202 is fixedly connected to the top of the water tank 2. It is designed to initially separate large particles of impurities and sludge in the coolant. An overflow hole 203 is provided on the upper edge of the sedimentation tank 202. When the coolant level exceeds the overflow hole 203, the excess coolant will flow back into the water tank 2 through the overflow hole 203.

[0023] Reference Figure 3The online cleaning mechanism 6 includes a cleaning frame 601 and a sludge collection box 607. The cleaning frame 601 houses a drive wheel 602 and a tensioning seat 603. A driven wheel 604 is located at the lower end of the tensioning seat 603. A porous adsorption belt 606 is provided on the drive wheel 602 and the driven wheel 604. The porous adsorption belt 606 has excellent adsorption performance and can adsorb fine metal powder and impurities in the coolant. In practical applications, to improve the adsorption effect, the driven wheel 604 can be further modified. A rotating agitator is provided; a motor 605 and a scraper 609 are provided on the outside of the cleaning frame 601. The output shaft of the motor 605 is connected to the drive wheel 602 to drive the porous adsorption belt 606 to rotate; the upper end of the scraper 609 is pressed against the porous adsorption belt 606, and the lower end is positioned above the sludge collection box 607. When the porous adsorption belt 606 moves to the scraper 609, the coolant containing fine metal powder adsorbed in it is scraped off and flows into the sludge collection box 607.

[0024] Reference Figure 4 The sludge collection box 607 is equipped with an overflow pipe 608 and a sludge collection plate 610. The lower end of the overflow pipe 608 is connected to the sedimentation tank 202 to drain excess coolant from the sludge collection box 607 back to the sedimentation tank 202. The sludge collection plate 610 is equipped with a hook 611 that matches the side wall of the sludge collection box 607. The upper end of the hook 611 is equipped with a handle 612 to facilitate cleaning impurities from the sludge collection box 607. The connecting seats on both sides of the sludge collection box 607 are equipped with strip-shaped sliding holes 613. The bolts on the water tank frame 1 pass through the strip-shaped sliding holes 613 to restrict the sludge collection box 607 to them, making it easy to adjust the position of the sludge collection box 607 to match the scraper 609.

[0025] Reference Figure 5 The cleaning rack 601 has a telescopic support plate 614 on its side. The scraper 609 is slidably mounted on the telescopic support plate 614. The telescopic support plate 614 has a telescopic strip hole 615 and a tension spring 617. The bottom of the scraper 609 has a guide post 616 that passes through the telescopic strip hole 615. The two ends of the tension spring 617 are connected to the guide post 616 and the telescopic support plate 614 respectively, thereby pressing the scraper 609 against the porous adsorption belt 606 to ensure the cleaning effect of the porous adsorption belt 606.

[0026] Reference Figure 6 The return water filtration mechanism 5 includes a filter box 501. A water inlet 504 is provided on one side of the filter box 501 to receive the coolant returning from the processing area. The bottom of the filter box 501 is connected to the sedimentation tank 202, and a top cover 503 is provided on the top for easy opening and cleaning of internal impurities. A detachable filter support 502 is provided inside the filter box 501. A filter screen is provided on the filter support 502 to filter out larger impurities in the coolant before it enters the sedimentation tank 202.

[0027] To facilitate understanding of this utility model, the following is combined with... Figure 1 - Figure 6 The working principle of this solution will be explained in detail:

[0028] Spray pump 4 sprays the coolant in water tank 2 through spray pipes to the processing area to cool the parts and tools. The returned coolant first enters the return water filter mechanism 5 for preliminary filtration, and then flows into the sedimentation tank 202 for sedimentation and separation. The porous adsorption belt 606 of the online cleaning mechanism 6 operates under the drive of motor 605, adsorbing fine metal powder and impurities in the coolant. Scraper 609 scrapes the impurities on the adsorption belt into the sludge collection box 607. When the impurities in the sludge collection box 607 accumulate to a certain level, they can be removed and cleaned through handle 612. The coolant, after multiple purification processes, finally flows back to water tank 2 for reuse.
