Description

Technical Field

[0001] This utility model relates to the technical field of circulating cooling devices, specifically a circulating cooling device for a high-speed drilling machine spindle. Background Technology

[0002] The cooling system of a machining center is a crucial component of CNC machine tools. Its primary function is to cool and lubricate the cutting tools and workpieces during machining, reducing heat buildup, extending tool life, and improving machining accuracy and surface finish. The design and performance of the cooling system directly impact the machining center's efficiency, workpiece quality, and equipment stability. It is a key component ensuring machining efficiency, accuracy, and tool life. Through appropriate cooling methods, efficient coolants, and intelligent control systems, the cooling system can effectively reduce heat accumulation during machining, improving machining quality and efficiency. In the future, with increasing demands for environmental protection and intelligent systems, cooling systems will evolve towards greater efficiency, environmental friendliness, and intelligence.

[0003] Existing machining centers have cooling systems installed next to the spindle. However, the coolant sprayed during machining causes debris to mix with the coolant, rendering it unusable. The coolant must be collected, filtered, and reused. Furthermore, existing machining centers lack a self-circulating coolant system, requiring manual addition and replacement, which reduces machining efficiency. Therefore, we propose a circulating cooling device for high-speed drilling machine spindles. Utility Model Content

[0004] The purpose of this utility model is to provide a circulating cooling device for a high-speed drilling machine spindle, which solves the problems of inconvenient self-circulation of coolant and the presence of waste debris in the coolant.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A circulating cooling device for a high-speed drilling machine spindle includes a machining center body, a machining center drive unit, and a machining spindle. A coolant spray gun is provided on the side of the machining spindle, and a water pump is provided on the rear side of the machining center body.

[0007] It also includes a circulation section for recycling and reusing the sprayed coolant;

[0008] The separation section is used to separate drill cuttings from the coolant, ensuring that the coolant can be reused.

[0009] The circulation unit includes a processing tray, which is fixedly connected to the inner side of the machining center body. A baffle is fixedly connected to the inner side of the machining center body. A recycling groove is formed on the surface of the machining center body. A motor is fixedly connected to the inner side of the machining center body. A small gear is passed through and fixedly connected to the output shaft of the motor. The small gear meshes with a large gear. A crossbar is fixedly connected to the inner side of the large gear. A rotating column is fixedly connected to the surface of the crossbar. The rotating column passes through the machining center body and is rotatably connected. A turntable is fixedly connected to the top surface of the rotating column. A brush rod is fixedly connected to the side of the turntable.

[0010] Preferably, a recycling bin is slidably connected through the inner side of the main body of the processing center, and a recycling hopper is fixedly connected through the top surface of the recycling bin.

[0011] Preferably, filter screen one and filter screen two are fixedly connected to the inner side of the recycling hopper.

[0012] Preferably, the water pump has two hoses at each end, with the hose on the left side of the water pump connected to the coolant spray gun and the hose on the right side of the water pump connected to the inside of the recovery tank.

[0013] Preferably, the number of brush rods is four sets, and the four sets of brush rods are arranged in a circular array with the center line of the turntable as the axis.

[0014] Preferably, the separating part includes a telescopic rod, the top end of which passes through and is slidably connected to a rotating column, and a spring is fixedly connected to the top surface of the telescopic rod, a connecting frame is fixedly connected to the bottom surface of the telescopic rod, and a brush is provided on the bottom surface of the connecting frame.

[0015] Preferably, a protrusion is fixedly connected to the inner side of the recycling hopper, and the top of the protrusion is higher than the bottom of the connecting frame.

[0016] By employing the above technical solution, this utility model provides a circulating cooling device for a high-speed drilling machine spindle. It possesses at least the following beneficial effects:

[0017] 1. This utility model, by starting the motor, the output shaft of the motor will drive the small gear to rotate, which in turn drives the large gear to rotate. When the large gear rotates, it will drive the turntable to rotate through the rotating column. When the turntable rotates, it will drive the four sets of brush rods located in the recycling tank to rotate, so that the four sets of brush rods continuously scrape the flowing coolant and waste debris into the recycling tank and into the recycling hopper. This avoids the waste debris clogging the column recycling tank and affecting the recycling and reuse of coolant, saves the cost of coolant use, reduces the frequency of coolant replenishment, and thus relatively improves the working efficiency of the machining center.

[0018] 2. In this utility model, when the large gear rotates, it drives the sliding telescopic rod to rotate as well. The telescopic rod then drives the connecting frame to rotate. However, when the connecting frame rotates, both ends of the connecting frame will continuously abut against the protrusions, causing the connecting frame to push the telescopic rod to compress the spring. As the connecting frame stops abutting against the protrusions, the spring will push the connecting frame back, causing the connecting frame to vibrate repeatedly. The brush at the bottom of the connecting frame can not only clean the filter screen but also intermittently insert the brush into the holes of the filter screen, thereby preventing the filter screen from becoming clogged and ensuring that the coolant can be effectively recycled and reused.

[0027] 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.

[0028] Please see Figures 1-6A circulating cooling device for a high-speed drilling machine spindle includes a machining center body 1, a machining center drive unit 4, and a machining spindle 5. A coolant spray gun 6 is installed on the side of the machining spindle 5, and a water pump 7 is installed on the rear side of the machining center body 1. It also includes a circulation section 2 for recycling the sprayed coolant and a separation section 3 for separating drill chips from the coolant to ensure its reuse. The circulation section 2 includes a machining tray 21, which is fixedly connected to the inner side of the machining center body 1. A baffle 22 is fixedly connected to the inner side of the machining center body 1. A recovery tank 23 is formed on the surface of the machining center body 1. The coolant spray gun 6 sprays coolant for cooling. When the coolant is sprayed, some of it directly hits the machining tray 21 and flows down the slope of the machining tray 21 into the recovery tank 23 and then into the recovery hopper 213. A portion of the coolant remains... The coolant is sprayed onto the baffle 22 and flows along the inclined surface of the inner side of the baffle 22 into the recovery tank 23 for recycling. A motor 25 is fixedly connected to the inner side of the machining center body 1. The output shaft of the motor 25 passes through and is fixedly connected to a small gear 26. The small gear 26 meshes with a large gear 27. A crossbar 28 is fixedly connected to the inner side of the large gear 27. A rotating column 29 is fixedly connected to the surface of the crossbar 28. The rotating column 29 passes through the machining center body 1 and is rotatably connected. A turntable 210 is fixedly connected to the top surface of the rotating column 29. A brush rod 211 is fixedly connected to the side of the turntable 210. When the machining spindle 5 is machining, waste chips will be generated. At this time, the motor 25 can be started. The output shaft of the motor 25 will drive the small gear 26 to rotate, and the small gear 26 will drive the large gear 27 to rotate. When the large gear 27 rotates, it will drive the turntable 210 to rotate together through the rotating column 29. A recycling bin 212 is slidably connected through the inner side of the machining center body 1, and a recycling hopper 213 is fixedly connected through the top surface of the recycling bin 212. Filter screen 1 214 and filter screen 215 are fixedly connected to the inner side of the recycling hopper 213. After waste debris and coolant are scraped from the recycling tank 23 into the recycling hopper 213 by the brush rod 211, some waste debris will fall onto the larger mesh filter screen 1 214, and some waste debris will fall onto the smaller mesh filter screen 215. The smaller mesh filter screen 215 will prevent waste debris from entering the recycling bin 212, thus avoiding blockage of the water pump 7's pipes. Two hoses are respectively installed at both ends of the water pump 7. The hose on the left side of the water pump 7 is connected to the coolant spray gun 6, and the hose on the right side of the water pump 7 is connected to the inside of the recovery tank 212. First, pull out the recovery tank 212, and then pour the coolant into the recovery tank 212 through the recovery hopper 213 fixedly connected to its top. Then, when the machining spindle 5 of the machining center body 1 is used, the coolant can be drawn out from the recovery tank 212 through the coolant spray gun 6 and the water pump 7, and the coolant can be sprayed out through the coolant spray gun 6 to cool down.There are four sets of brush rods 211. When the turntable 210 rotates, it drives the four sets of brush rods 211 to rotate in the recovery tank 23. This causes the four sets of brush rods 211 to continuously scrape the flowing coolant and waste debris into the recovery tank 23 and into the recovery hopper 213. When the connecting frame 33 rotates, both ends of the connecting frame 33 will continuously abut against the protrusion 35, causing the connecting frame 33 to push the telescopic rod 31 to compress the spring 32. After the connecting frame 33 stops abutting against the protrusion 35, the spring 32 will push the connecting frame 33 back, causing the connecting frame 33 to shake repeatedly. The brush 34 at the bottom of the connecting frame 33 can not only clean the filter screen 214, but also intermittently insert the brush 34 into the holes of the filter screen 214, thereby preventing the filter screen 214 from clogging and preventing waste debris from clogging the column recovery tank 23, which would affect the recovery and circulation of coolant. The four sets of brush rods 211 are arranged in a circular array with the center line of the turntable 210 as the axis.

[0029] The separation section 3 includes a telescopic rod 31, the top end of which passes through and is slidably connected to the rotating column 29. A spring 32 is fixedly connected to the top surface of the telescopic rod 31, and a connecting frame 33 is fixedly connected to the bottom surface of the telescopic rod 31. A brush 34 is provided on the bottom surface of the connecting frame 33. A protrusion 35 is fixedly connected to the inner side of the recovery hopper 213, and the top end of the protrusion 35 is higher than the bottom end of the connecting frame 33.

[0030] In use, first pull out the recovery tank 212, and then pour the coolant into the recovery tank 212 through the recovery hopper 213 fixedly connected to its top. Then, when the machining spindle 5 of the machining center body 1 is in use, the coolant can be drawn from the recovery tank 212 through the coolant spray gun 6 and the water pump 7, and the coolant is sprayed out through the coolant spray gun 6 for cooling. When the coolant is sprayed out, some of it will directly hit the machining tray 21 and flow down the slope of the machining tray 21 into the recovery trough 23 and into the recovery hopper 213. Some coolant will also be sprayed onto the baffle 22 and flow down the slope inside the baffle 22 into the recovery trough 23 for recycling. While the machining spindle 5 is machining... Waste debris will also be generated. At this time, motor 25 can be started. The output shaft of motor 25 will drive the pinion 26 to rotate, and the pinion 26 will drive the large gear 27 to rotate. When the large gear 27 rotates, it will drive the turntable 210 to rotate through the rotating column 29. When the turntable 210 rotates, it will drive the four sets of brush rods 211 to rotate in the recycling tank 23. This will cause the four sets of brush rods 211 to continuously scrape the flowing coolant and waste debris into the recycling tank 23 and into the recycling hopper 213. This will prevent the waste debris from clogging the column recycling tank 23 and affecting the recycling and reuse of coolant, thus saving the cost of coolant use, reducing the number of times coolant needs to be replenished, and thus relatively improving the working efficiency of the machining center body 1.

[0031] After the waste debris and coolant are scraped from the recovery tank 23 into the recovery hopper 213 by the brush rod 211, some of the waste debris will fall onto the larger mesh filter screen 214, and some will fall onto the smaller mesh filter screen 215. The smaller mesh filter screen 215 will prevent the waste debris from entering the recovery box 212, thus preventing blockage of the water pump 7's pipes. When the large gear 27 rotates, it will drive the slidingly connected telescopic rod 31 to rotate as well. The telescopic rod 31 will then drive the connecting frame 33 to rotate, but the connecting frame 33... During rotation, the two ends of the connecting frame 33 will continuously abut against the protrusion 35, causing the connecting frame 33 to push the telescopic rod 31 to compress the spring 32. As the connecting frame 33 stops abutting against the protrusion 35, the spring 32 will push back the connecting frame 33, causing the connecting frame 33 to shake repeatedly. The brush 34 at the bottom of the connecting frame 33 can not only clean the filter screen 214, but also intermittently insert the brush 34 into the holes of the filter screen 214, thereby preventing the filter screen 214 from becoming clogged and ensuring that the coolant can be effectively recycled and reused.
