Description

Technical Field

[0001] This application relates to the field of lead screw equipment technology, and more specifically, to a cooling control method based on 3D printed lead screws. Background Technology

[0002] Ball screw assemblies are high-precision and high-stability transmission devices. However, in some high-precision equipment, under long-term operation, the screw may elongate to a certain extent due to thermal expansion and contraction, which in turn affects the running accuracy of the ball screw assembly.

[0003] A lead screw cooling system is a device used to control the operating temperature of a lead screw. In many high-precision mechanical devices, the operating accuracy of the lead screw and nut is crucial to the overall performance of the equipment, and temperature changes significantly affect the accuracy of the lead screw and nut. The lead screw cooling system removes the heat generated by the operation of the lead screw and nut through a cooling medium, thereby stabilizing the temperature of the lead screw and nut.

[0004] Existing lead screw cooling systems typically use hollow lead screws, cooling them by circulating coolant inside. For example, patent application number 202410565848.2 discloses a lead screw constant-temperature cooling system, including a lead screw assembly, a drive motor, and a liquid chiller. The lead screw assembly includes a lead screw and a lead screw nut rotatably sleeved on the outside of the lead screw, with a lead screw through-hole along its axial direction. The drive motor includes a motor shaft that passes through the motor, with a shaft through-hole along its axial direction. The lead screw is sealed to the motor shaft, and the lead screw through-hole communicates with the shaft through-hole. The liquid chiller allows coolant to flow through the lead screw through-hole and the shaft through-hole. The liquid chiller allows coolant to flow through the lead screw through-hole and the shaft through-hole, carrying away the heat generated by the high-speed rotation of the motor and the heat generated by the friction between the lead screw nut and the lead screw, thus maintaining the lead screw at a constant temperature.

[0005] Because the lead screw needs to rotate during operation, the coolant circulation pipeline needs to be rotated and sealed with the lead screw, which increases the overall manufacturing difficulty of the device, reduces its service life, and significantly increases the manufacturing cost.

[0006] Therefore, existing technologies need to be improved. Summary of the Invention

[0064] Please see Figure 1 This embodiment provides a cooling control method based on a 3D printed lead screw, which includes the following steps:

[0065] S100: Pre-acquire the heat source generated by the rotation of the lead screw.

[0066] S200: Monitors the temperature of the heat source and calculates the cooling temperature of the heat source.

[0067] S300, based on the cooling temperature of the heat source, uses 3D printing to manufacture a liquid cooling kit 200 for cooling the heat source.

[0068] S400: Assemble the liquid cooling kit at the heat source position of the lead screw, and start the liquid cooling system according to the cooling temperature. The liquid cooling system removes the heat from the heat source to reduce the temperature of the heat source.

[0069] In this embodiment, a liquid cooling kit 200 for cooling the heat source is fabricated using 3D printing. 3D printing allows for customization of the shape and size of the liquid cooling kit 200 according to the specific requirements of the heat source. This ensures a tight fit between the liquid cooling kit 200 and the heat source of the lead screw 110, guaranteeing effective cooling and reducing assembly difficulty. Furthermore, 3D printing optimizes the flow channel layout of the liquid cooling kit 200. Due to the small size of the liquid cooling kit 200 for the lead screw 110, conventional machining and casting methods are insufficient to achieve the internal flow channels and structure. 3D printing enables the proper flow channel layout, improving cooling efficiency. Moreover, the liquid cooling kit 200 is an independent 3D printed part. The liquid cooling flow channels 250 within the liquid cooling kit 200 are connected to the liquid cooling system via inlet 260 and outlet 270, ensuring the sealing of the liquid cooling kit 200.

[0070] Therefore, in this embodiment, a liquid cooling kit 200 is manufactured using 3D printing, and the liquid cooling kit 200 removes heat from the heat source, enabling the lead screw 110 to cool down quickly, avoiding deformation of the lead screw 110 during the machining process, thereby improving the machining accuracy of the lead screw 110.

[0071] Specifically, step S100 includes:

[0072] The heat source of the lead screw 110 generated by its rotation, the heat source of the fixed end bearing seat generated by the rotation of the lead screw 110, the heat source of the motor end bearing seat generated by the rotation of the lead screw 110, and the heat source of the motor generated by the rotation of the lead screw 110 are obtained in advance.

[0073] For example, please see Figure 2 and Figure 3 The lead screw mechanism 100 includes a lead screw 110, a lead screw nut 120, a motor 130, a lead screw motor end 140, and a lead screw fixed end 150. The motor 130 is driven and connected to the lead screw 110. The lead screw 110 is provided with a movable lead screw nut 120. One end of the lead screw 110 is rotatably connected to the lead screw motor end 140, and the other end of the lead screw 110 is rotatably connected to the lead screw fixed end 150.

[0074] During high-speed operation, the lead screw 110 generates heat due to its rotation. For example, the lead nut 120 generates heat itself and at its connection point with the lead screw 110 after high-load, high-speed, and repeated motion. Heat is also generated at the connection points between the lead screw 110 and the fixed end 150, the motor end 140, and the motor 130. The fixed end bearing housing 220 serves as the mounting base for the lead screw 110 at the fixed end 150, and the motor end bearing housing 230 serves as the mounting base for the lead screw 110 at the motor end 140. In this embodiment, the motor end bearing housing 230 comprises two parts: a motor end bearing liquid cooling sleeve 232 with a liquid cooling channel 250, and a housing fixing seat 231 for fixing the motor end bearing liquid cooling sleeve 232. The motor end bearing liquid cooling sleeve 232 is embedded within the housing fixing seat 231, and the housing fixing seat 231 abuts against the motor pad 240 on the motor 130.

[0075] In this embodiment, the heat sources of the lead screw, the fixed end bearing housing, the motor end bearing housing, and the motor are obtained in advance, and the heat source temperature is monitored in real time to ensure that the liquid cooling system of the liquid cooling kit 200 can accurately adjust the cooling intensity, avoid excessive or insufficient cooling, improve the stability of the system, ensure that the lead screw 110 operates within the optimal temperature range, ensure its efficient and stable operation, and improve the overall performance of the lead screw 110.

[0076] Specifically, step S200 includes: monitoring the temperature of the nut heat source and calculating the cooling temperature of the nut heat source; monitoring the temperature of the fixed end bearing housing heat source and calculating the cooling temperature of the fixed end bearing housing heat source; monitoring the temperature of the motor end bearing housing heat source and calculating the cooling temperature of the motor end bearing housing heat source; and monitoring the temperature of the motor heat source and calculating the cooling temperature of the motor heat source.

[0077] In this embodiment, the cooling temperature of the nut 120 is calculated based on its actual temperature. This ensures that the nut cooling sleeve 210 effectively cools the nut 120, keeping it within its optimal temperature range. Similarly, the cooling temperature of the fixed-end bearing housing 220 is calculated based on its actual temperature, ensuring that the fixed-end bearing housing 220 effectively cools the fixed-end bearing, keeping it within its optimal temperature range. The cooling temperature of the motor-end bearing housing 230 is also calculated based on its actual temperature, ensuring that the motor-end bearing housing 230 effectively cools the motor-end bearing, keeping it within its optimal temperature range. Finally, the cooling temperature of the motor 130 is calculated based on its actual temperature, ensuring that the motor pad 240 effectively cools the motor 130, preventing heat transfer from the motor 130 to the lead screw 110.

[0078] For example, the minimum inlet temperature of the fixed end bearing housing 220 can be controlled at 15.00℃, and the maximum outlet temperature of the fixed end bearing housing 220 can be controlled at 20.00℃, so that the temperature control of the fixed end bearing is about 30℃.

[0079] The minimum inlet temperature of the nut cooling jacket 210 can be controlled at 15.00℃, and the maximum outlet temperature of the nut cooling jacket 210 can be controlled at 26.00℃, so that the temperature of the nut 120 is controlled at about 30℃.

[0080] The minimum inlet temperature of the motor end bearing housing 230 can be controlled at 15.00℃, and the maximum outlet temperature of the motor end bearing housing 230 can be controlled at 20.00℃, so that the temperature of the motor end bearing is controlled at approximately 30℃.

[0081] The minimum inlet temperature of the motor pad 240 can be controlled at 15.00℃, and the maximum outlet temperature of the motor pad 240 can be controlled at 25.00℃, so as to cool down the motor 130 and prevent the motor 130 from transferring heat to the lead screw 110.

[0082] Specifically, step S300 includes:

[0083] Based on the cooling temperature of the heat source of the filament, a filament cooling sleeve 210 for cooling the filament 120 is manufactured using 3D printing.

[0084] Based on the cooling temperature of the heat source of the fixed end bearing housing, a fixed end bearing housing 220 for cooling the fixed end bearing is manufactured using 3D printing.

[0085] Based on the cooling temperature of the heat source of the motor end bearing housing, a motor end bearing housing 230 for cooling the motor end bearing is manufactured using 3D printing.

[0086] Based on the cooling temperature of the motor heat source, a motor pad 240 for motor 130 is manufactured using 3D printing.

[0087] Please see Figure 4 and Figure 5 In this embodiment, 3D printing can design a ferrule cooling sleeve 210 structure that perfectly fits the ferrule 120, based on its specific shape and cooling temperature. This ensures close contact between the ferrule cooling sleeve 210 and the surface of the ferrule 120, improving cooling efficiency. Furthermore, 3D printing allows for the design of complex flow channel structures within the ferrule cooling sleeve 210, such as spiral channels wound around its inner wall. This optimizes the coolant flow path, improves heat dissipation efficiency, and reduces assembly difficulty.

[0088] 3D printing can design a structure that perfectly fits the fixed-end bearing according to the specific shape and cooling temperature of the fixed-end bearing housing 220, ensuring tight contact between the fixed-end bearing housing 220 and the surface of the fixed-end bearing and improving cooling efficiency. At the same time, 3D printing allows for the design of complex flow channel structures inside the fixed-end bearing housing 220, such as spiral channels wound around the inner wall of the fixed-end bearing housing 220, which can optimize the flow path of the coolant, improve the heat dissipation efficiency of the fixed-end bearing housing 220, and reduce assembly difficulty.

[0089] 3D printing can be used to design a structure that perfectly fits the motor bearing housing 230, based on its specific shape and cooling temperature, ensuring tight contact between the housing and the bearing surface and improving cooling efficiency. Furthermore, 3D printing allows for the design of complex flow channels within the bearing housing 230, such as spiral channels wound around its inner wall. This optimizes the coolant flow path, improves heat dissipation efficiency, and reduces assembly complexity.

[0090] 3D printing can be used to design a motor pad 240 that perfectly fits the motor 130, based on its specific shape and cooling temperature. This ensures tight contact between the motor 130 and the surface of the motor pad 240, improving cooling efficiency. Furthermore, 3D printing allows for the design of complex flow channel structures within the motor pad 240, optimizing the coolant flow path, improving heat dissipation efficiency, and reducing assembly complexity.

[0096] In this embodiment, the shell model and liquid cooling channel 3D model of the nut cooling sleeve 210 can be designed using 3shape software, resulting in the final nut cooling sleeve 3D model. The entire nut cooling sleeve 210 manufacturing process is simple to operate, with personalized digital 3D modeling design that conforms to the specific shape of the nut 120, ensuring close contact between the nut cooling sleeve 210 and the nut 120. Furthermore, a complex flow channel structure can be designed inside the nut cooling sleeve 210 to optimize the coolant flow path, improve the heat dissipation efficiency of the nut cooling sleeve 210, and reduce the assembly difficulty between the nut cooling sleeve 210 and the nut 120. Additionally, continuous air blowing during the printing process cleans the dust from the liquid cooling channel 250 of the nut cooling sleeve 210, improving print quality and promptly removing dust and debris generated during printing. This prevents them from adhering to the inner wall of the channel or clogging it, ensuring a smooth and intact internal flow channel, improving the sealing and flow unobstructedness of the liquid cooling channel 250, and reducing the need for subsequent processing.

[0115] In this embodiment, a motor pad 240 for cooling the motor 130 is fabricated using 3D printing. This allows the motor pad 240 to make close contact with the motor 130, and a flow channel structure can be printed inside the motor pad 240. This optimizes the flow path of the coolant, improves the heat dissipation efficiency of the motor 130, prevents the motor 130 from transferring heat to the lead screw 110, and reduces the assembly difficulty between the motor pad 240 and the motor 130. Furthermore, continuous air blowing during the printing process cleans the dust from the liquid cooling flow channel 250 of the motor pad 240, improving printing quality, promptly removing dust and debris generated during printing, preventing them from adhering to the inner wall of the flow channel or clogging the flow channel, ensuring the smooth and intact interior of the flow channel, improving the sealing and flow unobstructedness of the liquid cooling flow channel 250, and reducing the need for subsequent processing.

[0116] Specifically, the steps of assembling the liquid cooling kit 200 at the heat source position of the lead screw 110 and activating the liquid cooling system according to the cooling temperature to remove heat from the heat source and reduce the temperature of the heat source include:

[0117] The nut cooling sleeve 210 is assembled onto the nut 120 of the lead screw 110, the fixed end bearing seat 220 is assembled onto the fixed end 150 of the lead screw, the motor end bearing seat 230 is assembled onto the motor end 140 of the lead screw, and the motor pad 240 is assembled between the housing fixing seat 231 and the motor 130.

[0118] The nut cooling sleeve 210, the fixed end bearing seat 220, the motor end bearing seat 230, and the motor pad 240 are assembled and connected to form a liquid cooling system.

[0119] The liquid cooling system is started. The liquid cooling system controls the cooling sleeve 210 to cool the heat source of the nut according to the cooling temperature of the nut heat source, the liquid cooling system controls the fixed end bearing seat 220 to cool the fixed end bearing seat heat source according to the cooling temperature of the fixed end bearing seat heat source, the liquid cooling system controls the motor end bearing seat 230 to cool the motor end bearing seat heat source according to the cooling temperature of the motor end bearing seat heat source, and the liquid cooling system controls the motor pad 240 to cool the motor heat source according to the cooling temperature of the motor heat source.

[0120] In this embodiment, the liquid cooling system can liquid cool the lead screw 120, the fixed end bearing seat 220, the motor end bearing seat 230, and the motor 130 according to the cooling temperature. The coolant carries away the heat from the lead screw 120, the fixed end bearing seat 220, the motor end bearing seat 230, and the motor 130, so that the lead screw 110 can be cooled quickly, avoiding deformation of the lead screw 110 during the machining process, thereby improving the machining accuracy of the lead screw 110.

[0121] Specifically, after the step of 3D printing to fabricate a liquid cooling kit 200 for cooling the heat source based on the cooling temperature of the heat source, the process further includes:

[0122] After 3D printing the liquid cooling kit 200, the liquid cooling kit 200 is precision machined, and then the liquid cooling kit 200 is assembled.

[0123] In this embodiment, since the liquid cooling kit 200 needs to be in close contact with the heat source to improve its cooling effect, the surface of the 3D-printed liquid cooling kit 200 is usually relatively rough and may contain textures or particles. This embodiment, by leaving margins in the 3D printing process and then precision machining it with a machine tool, ensures that key dimensions meet high precision requirements, such as the contact surface between the liquid cooling kit 200 and the heat source. Precision machining with a machine tool gives the liquid cooling kit 200 a smooth surface, meeting the assembly requirements of the liquid cooling kit 200 with the heat source and the mounting base.

[0124] In summary, this application discloses a cooling control method for a 3D-printed lead screw. The method includes the following steps: pre-acquiring the heat source generated by the rotation of the lead screw; monitoring the temperature of the heat source and calculating its cooling temperature; fabricating a liquid cooling kit for cooling the heat source using 3D printing based on the cooling temperature; assembling the liquid cooling kit at the heat source location on the lead screw; and activating the liquid cooling system according to the cooling temperature to remove heat from the heat source, thereby reducing its temperature. This application uses 3D printing to fabricate the liquid cooling kit and removes heat from the heat source, enabling rapid cooling of the lead screw and preventing deformation during machining, thus improving the machining accuracy of the lead screw.

[0125] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
