Description

Technical Field

[0001] This invention relates to the field of CNC machine tool heat dissipation technology, specifically CNC machine tool heat dissipation components. Background Technology

[0002] CNC machine tools are short for numerical control machine tools. They are automated machine tools equipped with a program control system. Information is input into the CNC device through an information carrier, and after calculation and processing, the CNC device sends out various control signals to control the machine tool's movements. The machine tool automatically processes parts according to the shape and size required by the drawings, solving the problem of processing complex, precise, small-batch, and multi-variety parts.

[0003] In CNC machine tool operation, the spindle is a crucial component. The machine tool spindle refers to the shaft that drives the workpiece or cutting tool to rotate on the machine tool. It typically consists of the spindle itself, bearings, and transmission components (gears or pulleys). In current spindle operation, a servo motor drives the spindle to move the cutting tool, and the bearings limit the spindle's rotation. However, the high-speed rotation of the spindle generates heat through friction with the bearings, making the spindle prone to overheating. Generally, grease is added to the spindle and inside the bearings to lubricate them and reduce the coefficient of friction, thereby reducing heat generation. However, current spindles are installed in relatively enclosed equipment housings. Since the spindle is a precision component, it needs to be housed within the equipment housing. The heat generated by the spindle accumulates inside the housing, making it difficult for the heat to dissipate, resulting in the spindle and bearings still experiencing high temperatures during operation. Temperature fluctuations can cause the spindle to become easily worn due to heat. Regarding CNC machine tool cooling components, a search revealed that patent CN202011132593.9 discloses a CNC machine tool spindle cooling device. This device continuously cools both the cutting position and the spindle bearings to prevent overheating and machine shutdown. However, this patent uses only one bearing to fix the spindle within the CNC machine tool, resulting in only one fixed force point. When the spindle's force is concentrated at the bearing during rotation, especially at high speeds, the transmission ratio between the spindle and bearing increases, leading to a higher coefficient of friction and faster heat generation. This can cause the amount of lubricating grease between the spindle and bearing to decrease due to heat, affecting the normal operation of the spindle. Summary of the Invention

[0004] The present invention aims to address the shortcomings of the prior art by providing a heat dissipation component for CNC machine tools. This component dissipates the heat generated by the spindle within the machine housing, preventing heat from being difficult to dissipate and causing high temperatures between the spindle and the main bearing during operation. This slows down the rate of heat-induced wear on the spindle, extending its service life. Furthermore, by increasing the fixed force points of the spindle within the machine housing through anti-wear components, the force on the spindle is dispersed, preventing the transmission ratio between the spindle and the main bearing from increasing at excessively high speeds, which would lead to a higher coefficient of friction. This further slows down the rate of heat generation from the spindle, thereby mitigating the drawback of easily depleted lubricating grease.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a CNC machine tool heat dissipation assembly, comprising: a CNC machine tool, wherein an equipment housing is provided inside the CNC machine tool near the top, a servo motor is installed inside the equipment housing near the top, a spindle is located at the bottom of the servo motor and extends through the outside of the equipment housing, a main bearing is located inside the equipment housing near the bottom and is rotatably connected to the spindle, a cutting tool is located at the bottom of the spindle, a heat dissipation assembly is located inside the equipment housing near the spindle for cooling the spindle, an anti-wear assembly is located inside the equipment housing near the servo motor for fixing and preventing wear on the spindle, and a protective assembly is located at the top of the equipment housing for providing friction reduction and wear protection for the heat dissipation assembly.

[0006] Furthermore, a worktable is provided inside the CNC machine tool near the bottom, a fixing component is provided on one side of the top of the worktable, and an mounting component is provided on the side of the top of the worktable away from the fixing component.

[0007] Furthermore, the heat dissipation assembly includes: a main gear mounted on the main shaft, secondary gears meshing with each other on opposite sides of the outer end of the main gear, an upper rotating shaft mounted on the top of the secondary gear, blades on both sides of the top of the upper rotating shaft, and heat exhaust ports located on both sides of the top of the equipment box near the blades, with heat exhaust pipes on the top of each heat exhaust port.

[0008] Furthermore, the bottom of the secondary gear is provided with a lower rotating shaft, and secondary bearings are respectively provided on both sides near the bottom of the equipment box, and the secondary bearings are rotatably connected to the lower rotating shaft.

[0009] Furthermore, the anti-wear component includes: a limiting block disposed on the main shaft, the limiting block having a sliding groove inside, limiting frames disposed on both sides near the top of the equipment box, a support rod disposed inside the limiting frames, and a steel roller rotatably connected to the support rod, the steel roller being slidably connected to the sliding groove.

[0010] Furthermore, cooling boxes are provided on both sides of the top of the CNC machine tool, and the heat exhaust pipe passes through the CNC machine tool and extends into the interior of the cooling box. An oil inlet pipe is provided through one side of the top of the cooling box, and an oil outlet pipe is provided through one side of the outer end of the cooling box. Both the outer ends of the oil inlet pipe and the oil outlet pipe are provided with sealing caps.

[0011] Furthermore, a liquid storage tank is provided on one side inside the equipment box. The liquid storage tank consists of an inlet pipe, a liquid pump, a delivery pipe, and a corrugated pipe, and the corrugated pipe passes through the equipment box and faces the cutting tool.

[0012] Furthermore, a waste trough is provided on the worktable, and a cleaning bracket is provided near the bottom of the CNC machine tool. The cleaning bracket has an arched filter screen plate, and a filter box is provided inside the cleaning bracket. Several through holes are provided on the top and bottom of the filter box. A fine filter plate is provided inside the filter box, and several fine filter plates are provided inside the fine filter plate. A collection box is provided at the bottom of the filter box. Chip discharge ports are provided on both sides of the outer end of the cleaning bracket near the filter screen plate. A collection cavity is formed between the outer end of the cleaning bracket and the interior of the CNC machine tool. A sealing door is rotatably connected to the outside of the CNC machine tool via a hinge.

[0013] Furthermore, grooves are respectively formed on opposite sides inside the filter box, and the fine filter plate is slidably connected to the grooves.

[0014] Furthermore, the protective component includes: an oil storage tank located on the top of the equipment box, an oil injection pipe extending through the top of the oil storage tank, an oil lubrication pipe located on one side of the outer end of the oil storage tank, a switch valve on the oil lubrication pipe, a through hole opened on the outer end of the oil storage tank near the oil lubrication pipe, and the oil lubrication pipe extending through the through hole into the interior of the equipment box, and a transparent observation window located on the outside of the oil storage tank.

[0015] The advantages of this invention are that the heat dissipation component dissipates the heat generated by the spindle inside the equipment housing, preventing the heat from being difficult to dissipate and causing high temperatures between the spindle and the main bearing during operation. This slows down the rate of heat wear on the spindle, extends its service life, and the power used by the heat dissipation component comes from the spindle, eliminating the need for an additional power mechanism and avoiding increased power consumption. When the spindle is working, the heat dissipation component runs simultaneously with the spindle to achieve the purpose of timely heat dissipation for the spindle.

[0016] Secondly, by increasing the fixed force points of the spindle in the equipment box through anti-wear components, the force of the spindle is dispersed, which avoids the transmission ratio between the spindle and the main bearing from increasing when the speed is too high, which would lead to an increase in the coefficient of friction of the spindle. This achieves the purpose of slowing down the heat generation rate of the spindle, thereby mitigating the disadvantage of easy reduction of lubricating grease.

[0017] Protective components can reduce friction generated during the operation of heat dissipation components, improve their wear resistance, and extend their service life. Attached Figure Description

[0030] This application provides a heat dissipation component for CNC machine tools. This component effectively dissipates heat generated by the spindle within the machine housing, preventing heat from being trapped and causing high temperatures between the spindle and bearing during operation. This slows down the rate of heat-induced wear on the spindle, extending its service life. Furthermore, by increasing the fixed stress points of the spindle within the machine housing through anti-wear components, the force on the spindle is dispersed, preventing an increase in the transmission ratio between the spindle and bearing at excessively high speeds, which would lead to a higher coefficient of friction. This further slows down the rate of heat generation from the spindle, mitigating the drawback of easily depleted lubricating grease. The following provides a detailed description of this CNC machine tool heat dissipation component. It should be noted that the order of description in the following embodiments is not intended to limit the preferred order of the embodiments.

[0031] This application will now be described in detail with reference to the accompanying drawings and specific embodiments. Please refer to... Figure 1-11This embodiment provides a CNC machine tool heat dissipation assembly, comprising: a CNC machine tool 1, an equipment housing 101 located near the top of the CNC machine tool 1, a servo motor 102 installed near the top of the equipment housing 101, a spindle 103 located at the bottom of the servo motor 102 and extending through the outside of the equipment housing 101, a main bearing 104 located near the bottom of the equipment housing 101 and rotatably connected to the spindle 103, a cutting tool 105 located at the bottom of the spindle 103, a heat dissipation assembly located inside the equipment housing 101 near the spindle 103 for cooling the spindle 103, an anti-wear assembly located inside the equipment housing 101 near the servo motor 102 for fixing and preventing wear on the spindle 103, and a protective assembly located at the top of the equipment housing 101 for providing friction reduction and wear protection to the heat dissipation assembly.

[0032] In this embodiment, the CNC machine tool heat dissipation assembly mainly includes the CNC machine tool 1, equipment box 101, servo motor 102, spindle 103, main bearing 104, cutting tool 105, heat dissipation assembly, and anti-wear assembly.

[0033] The CNC machine tool heat dissipation component dissipates the heat generated by the spindle 103 within the equipment housing 101, preventing the heat from being difficult to dissipate and causing high temperatures between the spindle 103 and the main bearing 104 during operation. This slows down the rate of heat wear on the spindle 103 and extends its service life. Secondly, the anti-wear component increases the fixed force points of the spindle 103 within the equipment housing 101, dispersing the force on the spindle 103. This prevents the transmission ratio between the spindle 103 and the main bearing 104 from increasing at excessively high speeds, which would lead to a higher coefficient of friction in the spindle 103. This slows down the rate of heat generation from the spindle and mitigates the drawback of easily depleted lubricating grease.

[0034] In some embodiments, a worktable 2 is provided inside the CNC machine tool 1 near the bottom. A fixing member 201 is provided on one side of the top of the worktable 2, and a mounting member 202 is provided on the side of the top of the worktable 2 away from the fixing member 201. When the CNC machine tool 1 is in use, the workpiece is placed on the worktable 2, and the two ends of the workpiece are fixed by the fixing member 201 and the mounting member 202 respectively. The spindle 103 is driven by the servo motor 102, so that the spindle 103 drives the tool 105 to rotate at high speed. The tool 105 drills holes in the workpiece. During the high-speed rotation of the spindle 103, it will rotate with the main bearing 104. The main bearing 104 limits the rotation of the spindle 103 at a fixed point to ensure the stable operation of the spindle 103.

[0035] In some embodiments, the heat dissipation assembly includes: a main gear 3 mounted on a main shaft 103, with secondary gears 301 meshing with each other on opposite sides of the outer end of the main gear 3; an upper rotating shaft 302 mounted on the top of the secondary gear 301; blades 303 on both sides of the top of the upper rotating shaft 302; and heat exhaust ports 304 located on both sides of the top of the equipment housing 101 near the blades 303. Each heat exhaust port 304 has a heat exhaust pipe 305 on its top. During use, the main gear 3 on the main shaft 103 drives the secondary gears 301 to rotate, causing the upper rotating shaft 302 on the top of the secondary gears 301 to drive the blades 303 to rotate. Under the force of high-speed rotation, the blades 303 rotate rapidly. The high-speed rotation generates airflow, drawing heat from the equipment housing 101 to the heat exhaust port 304. The heat is then discharged through the heat exhaust port 304 into the heat exhaust pipe 305, from which the heat generated by the main shaft 103 is expelled. This process empties the heat from the equipment housing 101, preventing heat from being difficult to dissipate and causing high temperatures between the main shaft 103 and the main bearing 104 during operation. This slows down the rate of heat wear on the main shaft 103 and extends its service life. The power for the heat dissipation component comes from the main shaft 103, eliminating the need for an additional power mechanism and avoiding increased energy consumption. When the main shaft 103 is working, the heat dissipation component operates simultaneously with the main shaft 103, achieving the purpose of timely heat dissipation for the main shaft 103.

[0036] In some embodiments, the secondary gear 301 is provided with a lower rotating shaft 306 at its bottom, and secondary bearings 307 are respectively provided on both sides near the bottom of the equipment box 101. The secondary bearings 307 are rotatably connected to the lower rotating shaft 306. During the rotation of the secondary gear 301, the secondary gear 301 is supported and placed by the lower rotating shaft 306. After the secondary gear 301 is subjected to force and rotates, the lower rotating shaft 306 and the secondary bearings 307 rotate, ensuring that the secondary gear 301 and the main gear 3 operate stably.

[0037] In some embodiments, the anti-wear component includes: a limiting block 4 disposed on the spindle 103, the limiting block 4 having a groove 401 inside; limiting frames 5 disposed on both sides near the top of the equipment housing 101; a support rod 501 disposed inside the limiting frame 5; and a steel roller 502 rotatably connected to the support rod 501, with the steel roller 502 slidably connected to the groove 401. During the operation of the spindle 103, based on the fixed-point limiting rotation of the main bearing 104, when the spindle 103 rotates, the groove 401 inside the limiting block 4 will rotate with the steel roller 502 inside the limiting frame 5, increasing the wear resistance of the spindle 103 within the equipment housing. The fixed force-bearing point within 101 disperses the force on the spindle 103, preventing the transmission ratio between the spindle 103 and the main bearing 104 from increasing under excessively high speeds. This would increase the coefficient of friction of the spindle 103, thereby slowing down the heat generation rate of the spindle and mitigating the drawback of easily reduced lubricating grease. When in use, the steel roller 502 is supported by the support rod 501 and placed on the same horizontal line as the slide groove 401. The limit frame 5 provides space for movement, ensuring that the rotation of the steel roller 502 and the slide groove 401 is unimpeded, thus ensuring that the spindle 103 can work normally.

[0038] In some embodiments, cooling boxes 6 are respectively provided on both sides of the top of the CNC machine tool 1, and the heat exhaust pipe 305 passes through the CNC machine tool 1 and extends into the interior of the cooling box 6. An oil inlet pipe 601 is provided through one side of the top of the cooling box 6, and an oil outlet pipe 602 is provided through one side of the outer end of the cooling box 6. Both the outer ends of the oil inlet pipe 601 and the oil outlet pipe 602 are provided with sealing caps. When the CNC machine tool 1 is in use, cooling oil is added from the oil inlet pipe 601 into the cooling box 6 for storage. When the heat exhaust pipe 305 exhausts heat and comes into contact with the cooling oil inside the cooling box 6, the cooling oil will cool down the heat inside the heat exhaust pipe 305, preventing the heat exhaust from increasing the indoor temperature in the workshop. After the cooling oil is heated, it can be discharged from the oil outlet pipe 602, and new cooling oil can be added from the oil inlet pipe 601 for cooling and reuse.

[0039] In some embodiments, a liquid storage tank 7 is provided on one side inside the equipment box 101. The liquid storage tank 7 consists of an inlet pipe, a liquid pump, a liquid delivery pipe, and a corrugated pipe. The corrugated pipe passes through the equipment box 101 and faces the tool 105. When the tool 105 is drilling a hole in the workpiece, coolant is added from the inlet pipe to the liquid storage tank 7. The liquid pump draws the coolant into the liquid delivery pipe and sprays the coolant through the corrugated pipe to the tool 105 to cool the tool 105 and prevent the tool 105 from being worn due to high temperature. The corrugated pipe allows for easy adjustment of the direction of the coolant spray, making it convenient to use.

[0040] In some embodiments, a waste trough 8 is provided on the workbench 2, and a cleaning bracket 9 is provided near the bottom of the CNC machine tool 1. An arched filter screen 901 is mounted on the cleaning bracket 9, and a filter box 902 is provided inside the cleaning bracket 9. Several through holes 903 are provided at the top and bottom of the filter box 902, and a fine filter plate 904 is provided inside the filter box 902. Several fine filter plates 905 are provided inside the fine filter plate 904. A collection box 906 is provided at the bottom of the filter box 902. Chip discharge ports 907 are provided on both sides of the outer end of the cleaning bracket 9 near the filter screen 901. A collection cavity 908 is formed between the outer end of the cleaning bracket 9 and the interior of the CNC machine tool 1. A sealing door is rotatably connected to the outside of the CNC machine tool 1 via a hinge. 909. When spraying coolant to cool the cutting tool 105, the coolant and debris flowing down from the cutting tool 105 will flow from the waste trough 8 into the cleaning bracket 9. The coolant and debris will be separated by the filter screen plate 901. The coolant will flow down from the filter screen plate 901 and into the filter box 902 through the through hole 903. The coolant will be finely filtered by the fine filter plate 904. After flowing into the fine filter plate 904, the fine filter plate 905 will further finely filter the coolant, removing the fine debris to prevent the pump from being blocked by the fine debris during recycling. The finely filtered coolant will flow into the collection box 906 through the through hole 903 at the bottom. The collection box 906 can be removed by opening the sealing door 909.

[0041] The debris screened on the filter plate 901 will be discharged from the debris discharge port 907 into the collection chamber 908 for easy collection and processing.

[0042] In some embodiments, grooves 910 are respectively provided on opposite sides inside the filter box 902, and the fine filter plate 904 is slidably connected to the grooves 910. After the fine filter plate 904 has been used for filtering impurities for a certain period of time, it can be pulled out from the grooves 910 to facilitate the replacement of a new fine filter plate 904, ensuring that it can be used normally for filtration when the coolant is recovered.

[0043] In some embodiments, the protective component includes: an oil tank 10 disposed on the top of the equipment housing 101, an oil filling pipe 1011 extending through the top of the oil tank 10, an oil lubrication pipe 1012 disposed on one side of the outer end of the oil tank 10, a switch valve 1013 disposed on the oil lubrication pipe 1012, a through hole 1014 opened on the outer end of the oil tank 10 near the oil lubrication pipe 1012, and the oil lubrication pipe 1012 passing through the through hole 1014 and extending into the interior of the equipment housing 101, and a transparent observation window 1015 disposed on the outside of the oil tank 10. During use, the main gear 3 drives the secondary gear 301 to rotate. Lubricating oil is added from the oil injection pipe 1011 to the oil reservoir 10 for storage and later use. After the main gear 3 and secondary gear 301 have been used for a certain period of time, the switch valve 1013 is opened, and the lubricating oil in the oil reservoir 10 is discharged through the oil lubrication pipe 1012. The lubricating oil flows onto the main shaft 103, allowing it to flow along the main shaft 103 to the main gear 3. When the main gear 3 and secondary gear 301 mesh and contact each other, the lubricating oil can spread on the main gear 3 and secondary gear 301, thereby reducing the friction between the main gear 3 and secondary gear 301, improving wear resistance, and extending their service life.

[0044] During use, the oil level inside the oil tank 10 can be observed at any time through the transparent observation window 1015, and the oil can be added in time when the oil is used up.
