Description

Technical Field

[0001] This utility model relates to the technical field of cooling and temperature reduction of mechanical transmission components, specifically a split cooling jacket mechanism. Background Technology

[0002] Linear motion pairs, such as lead screw pairs, generate a large amount of heat due to friction during high-speed or long-term operation, leading to temperature rise. Excessive temperature rise can seriously affect the accuracy, performance, and service life of the motion pairs, causing issues such as lubricant failure, material thermal deformation, and changes in fit clearances.

[0003] Currently, for some moving parts that generate significant heat, the common cooling method is to machine cooling channels internally. However, this approach is complex, costly, and difficult to modify for already manufactured products. External cooling solutions also exist, but they are often structurally complex, inconvenient to install, have low cooling efficiency, or cannot achieve precise automatic control.

[0004] Therefore, the aforementioned technical problems need to be solved. Utility Model Content

[0005] This utility model addresses the above-mentioned technical problems by providing a split cooling jacket mechanism. The installation structure is simple and does not damage the original structure of the moving parts. It can effectively cool the temperature of the moving parts during operation and prevent performance failure caused by excessive temperature during operation.

[0006] To achieve the above objectives, the technical solution of this utility model is as follows:

[0007] A split cooling jacket mechanism includes an upper cooling jacket, a lower cooling jacket, and a cooling medium generating device, wherein the upper cooling jacket and the lower cooling jacket are detachably connected and cover the outside of a moving part;

[0008] The upper and lower cooling sleeves are respectively provided with a plurality of cooling grooves on their opposing inner surfaces, and the upper and lower cooling sleeves are respectively provided with a plurality of cooling channels inside, the cooling channels being interconnected with the cooling grooves to form a reciprocating internal cooling flow channel;

[0009] The upper cooling sleeve is provided with a cooling inlet and an upper connecting port that communicate with the internal cooling channel, and the lower cooling sleeve is provided with a cooling outlet and a lower connecting port that communicate with the internal cooling channel.

[0010] The cooling medium generating device drives the cooling medium to circulate and is connected to the cooling inlet and cooling outlet respectively. The upper connecting port is connected to the lower connecting port, and together with the internal cooling flow channel, they form a closed-loop circulation circuit for the cooling medium to flow.

[0011] The upper and lower cooling jackets are detachably connected and cover the outside of the moving parts. Several cooling grooves are machined on the inner surface of the two cooling jackets, and cooling channels machined inside them connect these cooling grooves to form a reciprocating internal cooling flow channel, thereby significantly increasing the heat exchange area and the flow path of the cooling medium.

[0012] The upper cooling jacket has a cooling inlet and an upper connecting port, while the lower cooling jacket has a cooling outlet and a lower connecting port. The upper and lower connecting ports are connected by pipes. The outlet of the cooling medium generator is connected to the cooling inlet via a pipe, and its inlet is connected to the cooling outlet via a return pipe. Thus, driven by the cooling medium generator, the cooling medium flows through the cooling inlet, the internal cooling channels of the upper cooling jacket, the upper connecting port, the lower connecting port, the internal cooling channels of the lower cooling jacket, and the cooling outlet, finally returning to the cooling medium generator, forming a complete closed-loop circulation circuit, achieving continuous and efficient cooling of the moving parts.

[0013] A further optimized design incorporates a through groove and a sealing groove on the cooling tank. The through groove connects to the cooling channel, and the sealing groove houses a pressure plate and a sealing element for sealing the through groove. This combination of pressure plate and sealing element ensures reliable sealing of the complex internal cooling channels under pressure, preventing leakage of the cooling medium.

[0014] A further optimized solution also includes a temperature sensor and a controller; the temperature sensor is disposed on the moving part for detecting its temperature; the controller is electrically connected to the temperature sensor and the cooling medium generating device for controlling the start and stop of the cooling medium generating device according to the temperature detected by the temperature sensor.

[0015] The closed-loop control system, consisting of a temperature sensor and a controller, enables intelligent start-stop with cooling only when needed, effectively controlling the core temperature of moving parts while avoiding energy waste.

[0016] In a further optimized design, the moving component is a lead screw or guide rail of a linear motion mechanism.

[0017] In a further optimized design, the upper and lower cooling sleeves are connected by fasteners; the upper cooling sleeve is provided with mounting holes, and the lower cooling sleeve is provided with threaded holes corresponding to the mounting holes. Connecting screws pass through the mounting holes and are screwed into the threaded holes to achieve fastening.

[0018] The upper and lower cooling jackets are connected by connecting screws, making installation and disassembly convenient without requiring any modification to existing moving parts. It has wide applicability and is easy to maintain.

[0019] Compared with the prior art, the split cooling jacket mechanism of this utility model has the following technical advantages:

[0020] 1. Modular split design: The upper and lower cooling jackets are connected by screws, making installation and disassembly extremely convenient. No modifications are required to existing moving parts, making it widely applicable and easy to maintain.

[0021] 2. Reciprocating internal cooling channels: The unique internal serpentine cooling channel design results in a long flow path for the cooling medium, ensuring sufficient heat exchange with the cooling jacket and achieving a cooling efficiency far superior to simple channels.

[0022] 3. Intelligent temperature control and energy saving: The closed-loop control system composed of temperature sensors and controllers realizes intelligent start-stop with cooling only when needed, effectively controlling the core temperature of moving parts and avoiding energy waste.

[0035] The present invention will now be described in further detail with reference to the embodiments shown in the accompanying drawings.

[0036] like Figures 1 to 11 As shown, this invention provides a specific embodiment of the split cooling jacket mechanism.

[0037] like Figure 1 and Figure 6 As shown, the split cooling jacket mechanism of this embodiment includes an upper cooling jacket 1, a lower cooling jacket 2, and a cooling medium generating device 3. The upper cooling jacket 1 and the lower cooling jacket 2 are detachably connected and cover the outside of the moving part 12. Figure 11 As shown, the moving part 12 is a lead screw of a linear motion mechanism.

[0038] like Figures 2 to 5 As shown, several cooling grooves 4a are respectively provided on the inner surfaces of the upper cooling sleeve 1 and the lower cooling sleeve 2, and several cooling channels 4b are respectively provided inside the upper cooling sleeve 1 and the lower cooling sleeve 2. The cooling channels 4b are interconnected with the cooling grooves 4a to form a reciprocating internal cooling channel 4.

[0039] like Figure 2 and Figure 7 As shown, the upper cooling jacket 1 is provided with a cooling inlet 5 and an upper connecting port 6 that communicate with the internal cooling channel 4, and the lower cooling jacket 2 is provided with a cooling outlet 7 and a lower connecting port 8 that communicate with the internal cooling channel 4.

[0040] like Figure 11 As shown, the cooling medium generating device 3 drives the cooling medium circulation and connects to the cooling inlet 5 and the cooling outlet 7 respectively. The upper connecting port 6 is connected to the lower connecting port 8 through the connecting pipe 14, and together with the internal cooling flow channel 4, they form a closed-loop circulation circuit for the cooling medium to flow.

[0041] The upper cooling jacket 1 and the lower cooling jacket 2 are detachably connected and cover the outside of the moving part 12. Several cooling grooves 4a are machined on the inner surface of the two cooling jackets, and cooling channels 4b machined inside them connect these cooling grooves 4a to form a reciprocating internal cooling flow channel 4, thereby greatly increasing the heat exchange area and the flow path of the cooling medium.

[0042] The upper cooling jacket 1 is equipped with a cooling inlet 5 and an upper connecting port 6, while the lower cooling jacket 2 is equipped with a cooling outlet 7 and a lower connecting port 8. The upper and lower connecting ports 8 are connected by pipes. The outlet of the cooling medium generating device 3 is connected to the cooling inlet 5 through a cooling medium inlet pipe 15, and its inlet is connected to the cooling outlet 7 through a cooling medium return pipe 16. Thus, driven by the cooling medium generating device 3, the cooling medium flows through the cooling medium inlet pipe 15, the cooling inlet 5, the internal cooling channel 4 of the upper cooling jacket 1, the upper connecting port 6, the lower connecting port 8, the internal cooling channel 4 of the lower cooling jacket 2, the cooling outlet 7, and the cooling medium return pipe 16, finally returning to the cooling medium generating device 3, forming a complete closed-loop circulation circuit, achieving continuous and efficient cooling of the moving parts 12.

[0043] like Figure 4 , Figure 5 , Figure 9 and Figure 10 As shown, the cooling tank 4a is provided with a through groove 4c and a sealing groove 4d. The through groove 4c connects to the cooling channel 4b. The sealing groove 4d is equipped with a pressure plate 4e and a sealing element 4f to seal the through groove 4c. The sealing structure combining the pressure plate 4e and the sealing element 4f ensures the sealing reliability of the complex internal cooling channel 4 under pressure and prevents leakage of the cooling medium.

[0044] like Figure 6 As shown, the split cooling jacket mechanism also includes a temperature sensor 9 and a controller 10; the temperature sensor 9 is disposed on the moving part 12 and is used to detect its temperature; the controller 10 is electrically connected to the temperature sensor 9 and the cooling medium generating device 3 through a control line 13, and is used to control the start and stop of the cooling medium generating device 3 according to the temperature detected by the temperature sensor 9.

[0045] The closed-loop control system consisting of temperature sensor 9 and controller 10 enables intelligent start-stop with cooling only when needed, effectively controlling the core temperature of moving parts 12 while avoiding energy waste.

[0048] The working process of the above-mentioned split cooling jacket mechanism is as follows:

[0049] 1) The normal operating temperature required for the moving part 12 during axial movement is below T0. When the controller 10 detects that the temperature of the moving part 12 exceeds the limit through the temperature sensor 9, the controller 10 controls the cooling medium release device to operate through the control line 13.

[0050] 2) The cooling medium enters the cooling inlet 5 of the upper cooling jacket 1 through the cooling medium inlet pipe 15, enters the through groove 4c through the cooling channel 4b, and then flows in the opposite direction through another cooling channel 4b into another through groove 4c, and so on in a repeated cycle.

[0051] 3) The cooling medium flows into the lower cooling jacket 2 through the connecting pipe 14, and circulates in the cooling channel 4b and cooling tank 4a of the lower cooling jacket 2. Finally, it flows back to the cooling medium generating device 3 through the cooling medium return pipe 16. One cooling process is completed, and the cycle repeats until the temperature sensor 9 detects that the temperature of the moving part 12 has dropped to T0, at which point the cooling medium generating device 3 stops operating.

[0052] The split cooling jacket mechanism has a simple installation structure and does not damage the original structure of the moving parts; it can effectively cool the temperature of the moving parts during operation and prevent performance failure caused by excessive temperature during operation.
