Description

Technical Field

[0001] This invention belongs to the field of machining center technology, specifically a coolant circulation system for machining centers. Background Technology

[0002] Machining centers evolved from CNC milling machines. The biggest difference between them is that machining centers have the ability to automatically change machining tools. By installing tools for different purposes on the tool magazine, the machining tools on the spindle can be changed in one setup through an automatic tool changer, thus realizing multiple machining functions.

[0003] The heat and debris generated during the high-speed cutting process of a machining center adhere to the worktable or workpiece surface, which can adversely affect the machining accuracy of the workpiece and the equipment itself. Therefore, the cooling device of the machining center cools and lubricates the cutting tools and workpieces by spraying coolant.

[0004] Coolant is expensive, and its recycling can reduce production costs. However, current technology does not achieve a high rate of removing visible iron filings from the coolant during recycling. If the visible iron filings are not cleaned properly, it will affect the processing accuracy and the equipment itself, and will also cause the coolant to breed bacteria, deteriorate, and smell bad.

[0043] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0044] like Figures 1 to 6 As shown, the present invention demonstrates a coolant circulation system for a machining center;

[0045] The device includes a housing 1 and a collection port 2. The collection port 2 is located on the top of the housing 1. The top of the housing 1 is surrounded by an overflow-proof edge to prevent coolant from overflowing. A first rotating hole 101 is correspondingly located at the top of the first and second sides of the housing 1. A discharge port 102 is located on the second side of the housing 1, below the first rotating hole 101. A transmission trough 3 is installed below the collection port 2. Both ends of the transmission trough 3 are fixed to the inner wall of the housing 1, and one end is connected to the discharge port 102. An auger 3 is installed inside the transmission trough 3. 01, the two ends of the auger 301's rotating shaft are rotatably connected to the first rotating hole 101; a conveying motor 302 is fixed to the first side of the housing 1 by a fixing block, and the output end of the conveying motor 302 is fixed to the rotating shaft of the auger 301 at the end away from the discharge port 102; a leakage hole is provided at the bottom of the transmission trough 3 for coolant to flow downwards; a filter screen 4 is installed below the transmission trough 3 and fixed to the inner wall of the housing 1; a filter cloth 5 is installed below the filter screen 4 and fixed to the inner wall of the housing 1; a second... There is one or more rotating holes. An adsorption cylinder 6 is installed inside the second rotating hole. The second rotating hole is rotatably connected to the adsorption cylinder 6. One end of the adsorption cylinder 6 extends into the interior of the housing 1, and the other end outside the housing 1 is open. A first pulley 601 is fitted onto the open end of the adsorption cylinder 6. The first pulley 601 is fixed to the surface of the adsorption cylinder 6. A mounting plate is fixed to the first side of the housing 1, and a rotating cylinder motor 602 is fixed to the mounting plate. A second pulley 602 is fixed to the output end of the rotating cylinder motor 602. The second pulley 603 is connected to the first pulley 601 via belt drive. A magnetic rod 8 is provided inside the adsorption drum 6. The magnetic rod 8 is slidably connected to the inner wall of the adsorption drum 6 and one end extends out of the adsorption drum 6. A collection tray 9 is installed below the adsorption drum 6. A water outlet hole 901 is opened at the bottom of the collection tray 9. A drain pipe 902 is installed below the water outlet hole 901. The drain pipe 902 is snapped into the water outlet hole 901. The drain pipe 902 is fixed to the bottom of the box 1 by the mounting base 903.

[0046] Specifically, in practical applications at machining centers, upon starting the system, coolant mixed with iron filings enters the transfer tank 3 from the collection port 2 at the top of the housing 1. The coolant flows down through the drain holes in the transfer tank 3. Driven by the drive motor, the auger 301 transfers the iron filings to the discharge port 102 for discharge. The coolant then flows to the filter screen 4, which filters out visible iron filings. The coolant then flows to the filter cloth 5, which filters the coolant again. Driven by the rotary drum motor 602, as the coolant flows through the adsorption drum 6, the rotating drum... The adsorption drum 6 agitates the coolant. Because a magnetic rod 8 is installed inside the adsorption drum 6, iron filings in the coolant that are not filtered out by the filter screen and filter cloth are adsorbed by the adsorption drum 6. As the adsorption drum 6 rotates, its surface can fully contact the visible iron filings in the coolant. The iron filings that are not filtered out by the filter screen and filter cloth are adsorbed on the surface of the adsorption drum 6. At the same time, the rotating adsorption drum 6 agitates the coolant, causing the heat in the coolant to dissipate. After being cleaned of impurities, the coolant flows from the water outlet 901 to the drain pipe 902 and is then recycled back to the coolant tank, completing the recycling process.

[0047] The adsorption drum 6 can adsorb visible iron filings in the coolant, separating them from the coolant. When the adsorption drum 6 rotates, it agitates the coolant to dissipate heat. The combination of the perforated holes, filter screen 4, filter cloth 5, and adsorption drum 6 removes impurities from the coolant layer by layer, reducing the visible iron filings in the coolant, improving the impurity removal rate of the coolant, and making it more conducive to the heat dissipation, recycling, and reuse of the coolant.

[0048] In other embodiments of the present invention, the surface of the portion of the adsorption drum 6 that extends into the box body 1 is provided with spiral patterns.

[0049] Generally, the coolant is filtered through the filter cloth 5 to remove visible iron filings. When the coolant flows through the adsorption drum 6, the adsorption drum 6 agitates the coolant. Because the adsorption drum 6 is equipped with magnetic rods 8, the visible iron filings in the coolant are adsorbed by the adsorption drum 6. Because the surface of the part of the adsorption drum 6 that extends into the tank 1 has spiral patterns, the surface area is increased, which increases the area that can be used to adsorb the visible iron filings in the coolant. Driven by the drum motor 602, the adsorption drum 6 rotates, and the surface can fully contact the visible iron filings in the coolant. The visible iron filings are adsorbed on the surface of the adsorption drum 6. The coolant after impurity removal flows from the outlet hole 901 to the drain pipe 902 and returns to the coolant tank, completing the recycling.

[0050] Spiral patterns are created on the surface of the part of the adsorption drum 6 that extends into the housing 1, which increases the surface area and the area used to adsorb visible iron filings in the coolant. This makes it more effective for the adsorption drum 6 to adsorb visible iron filings in the coolant, further improving the impurity removal rate of the coolant and making it more conducive to the recycling and reuse of the coolant.

[0051] In other embodiments of the present invention, an aeration head 7 is fixed to the inner wall of the third side of the box 1 and is located between the adsorption rotating cylinders 6. The aeration head 7 is connected to the air pump 701 through an air supply pipe. The air pump 701 is fixed on the mounting plate.

[0052] Specifically, the rotary drum motor 602 drives the adsorption drum 6, and the rotating adsorption drum 6 agitates the coolant to dissipate heat. At the same time, the adsorption drum 6 adsorbs visible iron filings in the surrounding coolant. The air pump 701 pumps air through the air supply pipe to the aeration head 7. The aeration head 7 pushes the visible iron filings in the coolant to the vicinity of the adsorption drum 6 through aeration. The adsorption drum 6 adsorbs the visible iron filings pushed to the vicinity onto its surface.

[0053] As we all know, machining centers generate a lot of heat when they are working. Coolant is used to cool and lubricate the workpiece and the cutting head. Therefore, the recovered coolant also contains a certain amount of heat. By aerating through the aerator head 7, the coolant can be cooled down.

[0054] At the same time, the aeration head 7 can agitate the coolant, allowing the iron filings in the coolant to come into full contact with the adsorption drum 6, which facilitates further adsorption of the iron filings by the adsorption drum 6 and further improves the removal rate of impurities from the coolant. Moreover, the gas aerated by the aeration head 7 can also cooperate with the rotating adsorption drum 6 to further cool the coolant, which is more conducive to the heat dissipation, recycling and reuse of the coolant.

[0055] In other embodiments of the present invention, a door 11 is provided on the fourth side of the box body 1. The end of the door 11 near the rotating motor is hinged to the box body 1. A sealing strip is fixed to the edge of the door 11. An observation window 1101 is provided on the surface of the door 11. A handle 1102 is fixed on the door 11.

[0056] Specifically, observe the adsorption of iron filings on the surface of the adsorption drum 6 through the observation window 1101 on the box door 11. When a large amount of iron filings are adsorbed on the adsorption drum 6, shut down the system. After the coolant is drained, open the box door 11 to clean the visible iron filings on the filter screen 4, filter cloth 5 and adsorption drum 6. The edge sealing strip of the box door 11 can prevent coolant from overflowing from the inside.

[0057] The use of the door 11 and the observation window 1101 facilitates observation of the iron filings adsorbed on the surface of the adsorption drum 6, allows for timely cleaning, ensures the continuous and effective operation of the adsorption drum 6, adsorbs visible iron filings in the coolant, and maintains a high impurity removal rate for the coolant.

[0058] In other embodiments of the present invention, the third side of the housing 1 is fixed to the input end of the pneumatic telescopic rod 802, the output end of the pneumatic telescopic rod 802 is fixed to the connecting plate 801, and the connecting plate 901 is fixed to the end of the magnetic rod 8 away from the adsorption drum 6.

[0059] Generally, when a large amount of iron filings are adsorbed on the adsorption drum 6, it is necessary to clean the iron filings on the adsorption drum 6. At this time, shut down the system and wait for the coolant to drain from the drain pipe 902. Then, start the pneumatic telescopic rod 802. When the output end of the pneumatic telescopic rod 802 extends, it pushes the connecting plate 801 away from the box 1. When the connecting plate 801 moves away from the box 1, it drives the magnetic rod 8 to be pulled out of the adsorption drum 6. At the same time as the magnetic rod 8 is pulled out of the adsorption drum 6, the iron filings that were originally adsorbed on the surface of the adsorption drum 6 begin to fall off. The fallen iron filings fall onto the collection tray 9. Open the box door 11, clean the visible iron filings on the filter screen 4 and filter cloth 5, remove the collection tray 9 from the drain pipe 902, take the collection tray 9 out of the box 1, clean the iron filings in the collection tray 9, and then reattach the collection tray 9 to the drain pipe 902. Close the box door 11 and then start the system.

[0060] The magnetic rod 8 is pulled out of the adsorption drum 6 by the pneumatic telescopic rod 802, causing the iron filings adsorbed on the adsorption drum 6 to lose their magnetic attraction and fall off. The collection tray 9 collects the fallen iron filings and cleans them off, so that the adsorption drum 6 can continue to effectively adsorb visible iron filings in the coolant, maintain a high impurity removal rate for the coolant, and is more conducive to the recycling and reuse of the coolant.

[0061] In other embodiments of the present invention, the end of the adsorption rotating cylinder 6 that contacts the inner wall of the box 1 is fitted with a magnetic shielding material.

[0062] Generally, when it is necessary to clean the visible iron filings on the adsorption drum 6, the pneumatic telescopic rod 802 is activated. When the output end of the pneumatic telescopic rod 802 extends, it pushes the connecting plate 801 away from the box 1. When the connecting plate 801 moves away from the box 1, it causes the magnetic rod 8 to be pulled out of the adsorption drum 6. At the same time as the magnetic rod 8 is pulled out of the adsorption drum 6, the iron filings that were originally adsorbed on the surface of the adsorption drum 6 begin to fall off. Some of the iron filings move along the direction of the magnetic rod 8 being pulled out due to the attraction of the magnet. Also, due to the magnetic attraction, these iron filings may be adsorbed on the inner wall of the box 1 and the end of the adsorption drum 6 that contacts the inner wall of the box 1.

[0063] A magnetic shielding material is fitted at the end of the adsorption drum 6 that contacts the inner wall of the box 1 to prevent some iron filings from adsorbing onto the inner wall of the box 1 and the end of the adsorption drum 6 that contacts the inner wall of the box 1 due to magnetic attraction when the magnetic rod 8 is pulled out of the adsorption drum 6. This makes the iron filings adsorbed on the adsorption drum 6 fall off more cleanly when the magnetic attraction is lost, which is more conducive to cleaning the iron filings adsorbed on the adsorption drum 6.

[0064] In other embodiments of the present invention, filter cotton is fixed inside the water outlet 901.

[0065] Specifically, when it is necessary to clean the iron filings adsorbed on the adsorption drum 6, the pneumatic telescopic rod 802 is activated. When the output end of the pneumatic telescopic rod 802 extends, it pushes the connecting plate 801 away from the box 1. When the connecting plate 801 moves away from the box 1, it causes the magnetic rod 8 to be pulled out of the adsorption drum 6. At the same time as the magnetic rod 8 is pulled out of the adsorption drum 6, the iron filings originally adsorbed on the surface of the adsorption drum 6 begin to fall off and fall onto the collection tray 9.

[0066] Fixing filter cotton in the outlet hole 901 can further filter the coolant when it enters the drain pipe 902, improve the removal rate of impurities from the coolant, and facilitate the recycling and reuse of the coolant. It can also prevent iron filings falling into the collection tray 9 from entering the drain pipe 902, so as to avoid clogging the drain pipe 902 and hindering the recycling of coolant.

[0067] In other embodiments of the present invention, the end of the drain pipe 902 away from the outlet hole 901 is connected to the water pump 10 through a threaded joint, and the water pump 10 is used to pump the coolant back to the coolant tank.

[0068] Generally, the coolant flows from the outlet hole 901 into the drain pipe 902. Since the drain pipe 902 is connected to the water pump 10 through the threaded joint 904, the water pump 10 pumps the coolant back to the coolant tank, completing the removal of impurities, recovery, and recycling of the coolant.

[0069] The drain pipe 902 and the water pump 10 are connected by a threaded connector 904, which facilitates the maintenance and replacement of the water pump 10. The water pump 10 is used to pump the coolant back to the coolant tank, which facilitates the recycling and reuse of the coolant.
