[0002] During the processing of heat pipes, they need to be vacuumed to remove internal gases and impurities and improve their performance and quality. However, traditional vacuum equipment for heat pipe processing has the following shortcomings:

[0003] 1. Traditional vacuum devices often lack flexible adjustment mechanisms and cannot be adaptively adjusted according to the different sizes and shapes of heat pipes, resulting in poor vacuuming effect and affecting the processing quality of heat pipes. At the same time, during the vacuuming process, traditional vacuum devices do not fix the heat pipes firmly enough, which is prone to deviation or shaking, which not only affects the vacuuming effect but may also damage the heat pipes.

[0004] To this end, we proposed a vacuum device for heat pipe processing. Utility Model Content

[0005] The present invention aims to address the problem in the prior art that conventional vacuum devices often lack a flexible adjustment mechanism and are unable to adapt to the different sizes and shapes of heat pipes, resulting in poor vacuuming effect and affecting the processing quality of the heat pipes. At the same time, during the vacuuming process, conventional vacuum devices do not securely fix the heat pipes firmly enough, making them prone to deviation or shaking, which not only affects the vacuuming effect but may also damage the heat pipes. The present invention proposes a vacuum device for heat pipe processing.

[0006] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0009] The limiting assembly includes a first limiting plate and a second limiting plate respectively installed at the front end and the rear end of one side of the upper surface of the workbench by bolts, the middle parts of the first limiting plate and the second limiting plate are rotatably connected to a bidirectional screw rod, both ends of the bidirectional screw rod are threadedly connected to a clamping plate, one side of the two clamping plates is fixedly connected to a rubber pad, both sides of the first limiting plate and the second limiting plate are fixedly connected to a guide rod, the clamping plate is slidably connected to the guide rod, and is used to limit the heat pipe body;

[0010] The adjustment component includes a slider installed on one side of the upper end of the workbench, one side of the slider is engaged with a block, the block is engaged with the connecting pipe, and a slide groove is provided on one side of the upper end of the workbench, and the slider slides inside the slide groove to adjust the position of the connecting pipe.

[0011] In one possible design, the front end of the bidirectional screw rod passes through the first limit plate and is fixedly connected to the first gear. The upper end of the first limit plate is rotatably connected to the connecting shaft. The outer wall of the rear end of the connecting shaft is fixedly connected to the second gear. The first gear is meshed with the second gear and is used to drive the bidirectional screw rod.

[0012] The top end of the sliding block is fixedly connected to the support frame, and the upper end of the support frame is slidably connected to the adjusting frame. The outer walls of both sides of the adjusting frame are slidably sleeved with springs, and the lower end of the adjusting frame is fixedly connected to the third limit plate, and the upper and lower ends of the springs are respectively affixed to the inner top surface of the support frame and the upper surface of the third limit plate for pushing the adjusting frame. One side of the workbench is provided with a plurality of limit holes at the upper end of the slide groove, and the lower end of the adjusting frame is engaged with the limit holes for limiting the slider, and both sides of the lower end of the third limit plate are fixedly connected to limit rods, and the limit rods pass through the slider and the block for limiting the block.

[0013] In a possible design, the front end of the connecting shaft is fixedly connected to a rotating handle.

[0014] In a possible design, a protective cover is hingedly connected to the rear portion of the upper end of the workbench, and an observation window is provided at the front end of the protective cover.

[0015] In a possible design, self-locking universal wheels are fixedly connected to the four corners of the lower surface of the workbench.

[0016] In the present application, when in use, first, the heat pipe body to be processed is placed on the placement rack on the workbench. A one-way valve is provided on one side of the heat pipe body. The one-way valve is used to control the one-way flow of gas, ensuring that during the vacuum process, the gas can only flow from the inside of the heat pipe body to the outside, and will not flow in the opposite direction. Next, the position of the connecting pipe is adjusted by the adjusting component. Specifically, the position of the sliding slider in the slide groove is adjusted to align the connecting pipe with the one-way valve on the heat pipe body. Then, the clamping block is engaged with the connecting pipe, and the third limit plate at the lower end of the adjusting frame is engaged with the limit hole through the cooperation of the adjusting frame and the spring, thereby limiting the slider to ensure that the position of the connecting pipe is stable. At the same time, the limiting rod passes through the slider and the clamping block to further limit the clamping block to prevent it from moving during work. Then, the heat pipe body is limited by the limiting component. , by driving the rotating handle, the connecting shaft and the second gear are driven to rotate. Since the first gear is meshed with the second gear, the rotation of the second gear will drive the first gear and the bidirectional screw to rotate. The rotation of the bidirectional screw will cause the two clamping plates to move toward the middle along the guide rod until they are in close contact with the heat pipe body. The setting of the rubber pad increases the friction between the clamping plates and the heat pipe body, preventing the heat pipe body from deviating or shaking during the vacuuming process. Finally, the vacuum pump is started, and the vacuum pump vacuums the heat pipe body through the connecting pipe and the one-way valve. The extracted gas is discharged to the outside of the device through the air outlet of the vacuum pump and the air outlet pipe. During the vacuuming process, the vacuuming of the heat pipe body can be observed through the observation window. When the vacuuming is completed, the vacuum pump is turned off, the adjusting frame and the limit rod are loosened, and the connecting pipe is removed from the one-way valve to complete the entire vacuuming process.

[0017] In the present invention, the vacuum device for heat pipe processing can conveniently adjust the position of the connecting pipe by providing an adjustment component to align it with heat pipe bodies of different sizes and shapes. This flexible adjustment mechanism improves the adaptability and practicality of the device, making it applicable to a wider variety of heat pipe processing requirements. The limit assembly can firmly limit the heat pipe body to prevent it from shifting or shaking during the vacuuming process. This stable limit method not only improves the vacuuming effect, but also avoids damage caused by movement of the heat pipe body, thereby ensuring processing quality.

[0018] In the present invention, a vacuum device for heat pipe processing can limit the heat pipe body by turning a handle, and adjust the position of the connecting pipe by sliding a slider. This convenient operation method reduces the labor intensity of workers and improves work efficiency. The provision of an observation window allows for easy observation of the internal conditions of the heat pipe body to ensure a good vacuuming effect. This observation effect provides intuitive feedback to workers, allowing them to adjust operating parameters in a timely manner according to actual conditions, further improving processing quality. The provision of self-locking universal wheels allows for easy movement of the entire device. When the device needs to be fixed, the self-locking universal wheels can be locked. This design, which is easy to move and fix, makes the device suitable for different working environments and site requirements. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] In order to keep the following description of the embodiments of the present invention clear and concise, the present invention omits detailed descriptions of known functions and known components.

[0029] Example 1: Reference Figure 1-Figure 5 , a vacuum device comprising:

[0030] A workbench 1 is provided, with a vacuum pump 2 fixedly connected to one side of the inner bottom surface of the workbench 1, a connecting pipe 3 fixedly connected to the air inlet of the vacuum pump 2, and an air outlet of the vacuum pump 2 fixedly connected to an air outlet pipe 4. A threaded sleeve 5 is provided on the upper end sliding sleeve of the connecting pipe 3. A placement rack 8 is fixedly connected to one side and the middle of the upper surface of the workbench 1. A heat pipe body 7 is provided on the upper end of the placement rack 8. A one-way valve 6 is provided on one side of the heat pipe body 7. The one-way valve 6 is tightly fitted to the connecting pipe 3 and is threadedly connected to the threaded sleeve 5 for evacuating the heat pipe body 7.

[0031] The limiting assembly includes a first limiting plate 9 and a second limiting plate 10 respectively mounted on the front and rear ends of one side of the upper surface of the workbench 1 by bolts.

Both ends of the bidirectional screw rod 11 are threadedly connected to a clamping plate 12. One side of the two clamping plates 12 is fixedly connected to a rubber pad 13. Both sides of the inside of the first limiting plate 9 and the second limiting plate 10 are fixedly connected to a guide rod 14. The clamping plate 12 is slidably connected to the guide rod 14 and is used to limit the heat pipe body 7.

[0032] The adjustment component includes a slider 16 installed on one side of the upper end of the workbench 1, and a block 17 is snap-fitted on one side of the slider 16.

[0033] In the above technical solution, the heat pipe body 7 to be processed is placed on the placement rack 8 on the workbench 1, and a one-way valve 6 is provided on one side of the heat pipe body 7. The one-way valve 6 is used to control the one-way flow of gas, ensuring that during the vacuum process, the gas can only flow from the inside of the heat pipe body 7 to the outside, and will not flow in the opposite direction. Then, the position of the connecting pipe 3 is adjusted by the adjusting component. Specifically, the position of the sliding slider 16 in the slide groove 15 is used to align the connecting pipe 3 with the one-way valve 6 on the heat pipe body 7.

The first gear 23 is meshed with the second gear 24 to drive the bidirectional screw rod 11.

[0035] In the above technical solution, the first gear 23 is meshed with the second gear 24 , so the rotation of the second gear 24 drives the first gear 23 and the bidirectional screw rod 11 to rotate.

[0036] In one aspect of this embodiment, Figure 5 As shown, the upper end of the slider 16 is fixedly connected to the support frame 18, and the upper end of the support frame 18 is slidably connected to the adjustment frame 19. The outer walls on both sides of the adjustment frame 19 are slidably sleeved with springs 22, and the lower end of the adjustment frame 19 is fixedly connected to the third limit plate 20. The upper and lower ends of the spring 22 are respectively fitted with the inner top surface of the support frame 18 and the upper surface of the third limit plate 20 to push the adjustment frame 19. One side of the workbench 1 is provided with a plurality of limit holes 29 at the upper end of the slide groove 15.

Both sides of the lower end of the third limit plate 20 are fixedly connected to the limit rod 21. The limit rod 21 passes through the slider 16 and the block 17 to limit the block 17.

[0037] In the above technical solution, by using the adjustment frame 19 and the spring 22 in conjunction with each other, the third limit plate 20 at the lower end of the adjustment frame 19 is engaged with the limit hole 29, thereby limiting the slider 16 to ensure the stable position of the connecting pipe 3. At the same time, the limit rod 21 passes through the slider 16 and the block 17 to further limit the block 17 to prevent it from moving during operation.
