Description

Technical Field

[0001] This invention relates to the field of liquid cooling joint processing technology, specifically to an integrated milling and turning processing device for expansion and contraction type liquid cooling joints. Background Technology

[0002] Liquid cooling connectors, as key heat dissipation components, are widely used in electronic equipment, new energy vehicles, high-power lasers, and other fields. They are typically manufactured using metal tubing with complex internal and external structures (such as stepped outer walls, inner holes, flared ends, threads, or irregular cavities), requiring extremely high machining precision and dimensional tolerances.

[0003] In traditional production, processes such as external turning, internal drilling / reaming / shaping, and final cutting often need to be completed on multiple machines such as lathes, milling machines (or machining centers), and drilling machines. The workpiece needs to be disassembled, transferred, and re-clamped multiple times. Multiple clamping causes changes in the reference surface, resulting in repeated positioning errors, which affect the coaxiality, perpendicularity, and positional accuracy between various machining features. Transferring between processes and clamping adjustments consume a lot of auxiliary time, reducing overall production efficiency. Multiple machine tools are required, increasing equipment investment and factory space occupation. Summary of the Invention

This solves the problem that in current traditional production, processes such as external turning, internal drilling / reaming / shaping, and final cutting often need to be completed separately on multiple machines such as lathes, milling machines (or machining centers), and drilling machines. The workpiece needs to be disassembled, transferred, and re-clamped multiple times. Multiple clamping causes changes in the datum surface, resulting in repeated positioning errors, which affect the coaxiality, perpendicularity, and positional accuracy between various machining features. Transferring between processes and clamping adjustments consume a lot of auxiliary time, reducing overall production efficiency.

[0015] Compared with the prior art, the advantages of the present invention are as follows: 1. The workpiece of this invention is clamped in one go and supported by two-way centering through the clamping assembly and the left-end rotating block. In this state, the outer contour turning, inner hole machining, and final cutting are completed sequentially, fundamentally eliminating the repeated positioning errors caused by multiple clamping. Due to the unified datum, key geometric tolerances such as coaxiality, roundness, perpendicularity, and position between various machining features of the workpiece are more easily guaranteed. One-time clamping reduces the impact of clamping force changes and workpiece deformation on dimensional accuracy, resulting in higher consistency of part dimensions in mass production. It also saves a lot of non-cutting time such as handling, transferring, re-clamping, tool setting, and alignment of workpieces between different machines. The connection between processes is automatically completed inside the equipment, realizing continuous processing. 2. This invention integrates turning, milling, and cutting into a single machine, seamlessly connecting processes and eliminating the time spent transferring workpieces between machine tools, waiting, and resetting tools. The entire machining process can be automatically executed sequentially by controlling the clamping cylinder, first servo motor, third servo motor, second servo motor, and pushing cylinder through a preset program, greatly reducing manual intervention and achieving automation of the machining process. The first tool, second tool, and cutting tool are all detachable, facilitating replacement according to process requirements. The tool feeding assembly integrates height and longitudinal position adjustment functions, enabling quick and accurate positioning of the internal hole machining tool to the workpiece axis. 3. This invention can adapt to cylindrical workpieces of different diameters by adjusting the clamping sleeve of the clamping assembly. Processing dimensions, speed, rotation speed, and other parameters can all be preset through the control system, enabling the equipment to flexibly meet the processing needs of liquid-cooled joints of different specifications. One machine replaces the functions of multiple traditional machine tools, reducing equipment procurement and maintenance costs, while also reducing the floor space required for production. Automated processing reduces the skill requirements of operators, minimizes quality fluctuations caused by human error, and is conducive to stabilizing product quality and enabling large-scale production.

[0018] The following description is intended to disclose the invention and enable those skilled in the art to implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0019] Reference Figure 1 - Figure 8 As shown, a milling and turning integrated machining equipment for a liquid-cooled joint with an expansion and contraction design includes a base plate 1. Two vertical plates 2, arranged horizontally, are fixedly connected to the left side of the upper surface of the base plate 1. A tool feeding assembly 25 is installed on the right side of the right vertical plate 2 on the upper surface of the base plate 1. The tool feeding assembly 25, as the core milling tool feeding execution component, can precisely control the tool feed rate and feed speed to achieve precise milling of the liquid-cooled joint. A clamping assembly 24 for clamping the right end of the workpiece is installed on the left side of the right vertical plate 2. Support bars 8 are fixedly connected to the front and rear sides of the two vertical plates 2. Second guide rails 9 are fixedly connected above the two support bars 8. A moving plate 10 is slidably connected above the two sets of second guide rails 9 via sliding blocks. A lifting platform 11 is fixedly installed at the center of the upper part of the platform 10. A lifting threaded rod 12 is threadedly connected to the center of the lifting platform 11. The working principle of the lifting platform 11 can be referred to as the gate lifting device in water conservancy engineering. The specific principle will not be elaborated here. The bottom of the lifting threaded rod 12 passes through the moving plate 10 and is fixedly connected to the fixed plate 14. A first cutter 15 is detachably connected to the center of the bottom surface of the fixed plate 14. A first guide rod 13 is fixedly connected to both the front and rear sides of the lifting threaded rod 12 on the upper surface of the fixed plate 14. The two first guide rods 13 are slidably connected to the moving plate 10 through guide sleeves. The detachable design of the first cutter 15 makes it easy to replace different types of cutters according to processing needs in the future, thereby improving the processing adaptability of the equipment.

[0020] In one embodiment of the present invention, a connecting plate 17 is fixedly connected to the front side of each of the two upright plates 2. A first movable threaded rod 18 is rotatably connected between the two connecting plates 17. The first movable threaded rod 18 is threadedly connected to the bottom surface of the movable plate 10 through a threaded seat. A limiting post 16 is fixedly connected to the rear side of the upper surface of the fixed plate 14 to prevent the fixed plate 14 and the first movable threaded rod 18 from rigidly contacting each other. At least one connecting plate 17 is fixedly mounted on the side with a third servo motor 26 that drives the first movable threaded rod 18 to rotate. The limiting post 16 can effectively prevent the fixed plate 14 from rigidly contacting the first movable threaded rod 18 when it returns to its original position, avoiding collision damage between the two and ensuring processing safety. The third servo motor 26 can accurately control the rotation angle and speed of the first movable threaded rod 18, thereby achieving precise control of the moving distance of the movable plate 10 and improving the positional accuracy of milling and turning.

[0021] In one embodiment of the present invention, two sets of first pads 3 are fixedly connected to the upper surface of the base plate 1 on the right side of the left vertical plate 2. A first guide rail 4 is fixedly connected above each of the two first pads 3. A support plate 5 is slidably connected above the two sets of first guide rails 4 via a sliding block. A rotating block 6 supporting the left end of the workpiece is rotatably connected to the middle of the right side of the support plate 5. A clamping cylinder 7 that pushes the support plate 5 to move along the first guide rail 4 is fixedly installed on the left side of the left vertical plate 2. The rotating block 6 can provide stable support for the left end of the liquid-cooled joint workpiece. At the same time, the rotating connection method allows the supporting rotating block 6 to rotate synchronously with the workpiece. To avoid wear on the workpiece surface during support and ensure workpiece machining accuracy, the clamping cylinder 7 provides a stable and powerful driving force for the movement of the support plate 5. The cylinder drive has a rapid response and controllable thrust, which can precisely control the contact force between the support rotating block 6 and the left end of the workpiece. This ensures that the workpiece is stably supported and avoids excessive clamping that could cause workpiece deformation. It is suitable for the support requirements of liquid cooling joints of different lengths, and achieves symmetrical support and clamping of the left and right ends of the workpiece, further improving the stability of the workpiece during processing. The rotating block 6 is made of flexible material, and the magnitude of the clamping force can be judged by observing its deformation.

[0022] In one embodiment of the present invention, a side plate 19 is fixedly connected to the upper surface of the base plate 1 behind the right upright plate 2. A push cylinder 20 is fixedly installed on the upper rear side of the side plate 19. The output end of the push cylinder 20 passes through the rear side of the side plate 19 and is fixedly connected to a tool holder 22. A cutting blade 23 is detachably connected to the front side of the tool holder 22. Second guide rods 21 are fixedly connected to both the left and right ends of the rear side of the tool holder 22. The two second guide rods 21 are slidably connected to the side plate 19 through guide sleeves. The tool holder 22 can provide a stable mounting carrier for the detachably connected cutting blade 23. The detachable design of the cutting blade 23 facilitates later maintenance. The tool holder 22 can be replaced to adapt to the cutting requirements of liquid-cooled connectors of different sizes. The push cylinder 20 can drive the tool holder 22 and the cutting blade 23 to move back and forth, realize the precise feeding and resetting of the cutting blade 23, ensure the precise cutting of the liquid-cooled connector after processing, and improve processing efficiency. The two second guide rods 21 are slidably connected to the side plate 19 through the guide sleeve, which can provide double precise guidance for the back and forth movement of the tool holder 22, prevent the tool holder 22 from tilting or deviating when moving, ensure the precise position of the cutting blade 23 when cutting, avoid the workpiece scrapping caused by cutting deviation, and at the same time, the cooperation between the guide sleeve and the guide rod can reduce sliding friction and extend the service life of the components.

[0023] In one embodiment of the present invention, the clamping assembly 24 includes a hollow cylinder 2401 and a first servo motor 2403. The hollow cylinder 2401 is rotatably connected to the left side of the right side upright plate 2, and the first servo motor 2403 is fixedly installed behind the left side of the right side upright plate 2. A gear ring 2402 is fixedly connected to one end of the outer surface of the hollow cylinder 2401 near the right side upright plate 2. The hollow cylinder 2401 can provide a through-type clamping space for the workpiece, adapt to the structural characteristics of the expansion and contraction style liquid cooling joint, and can rotate synchronously with the workpiece to realize the turning process of the workpiece. The first servo motor 2403 can provide a precise and controllable driving force for the rotation of the workpiece. The gear ring 2402 can precisely cooperate with the power component to realize power transmission. At the same time, the gear ring 2402 is fixed to the outer surface of the hollow cylinder 2401, and the force is uniform, which can effectively disperse the torque during the rotation process and avoid local stress concentration leading to component damage.

[0024] In one embodiment of the present invention, the output end of the first servo motor 2403 passes through the side of the right vertical plate 2 and is fixedly connected to a first gear 2404. The first gear 2404 meshes with a gear ring 2402. A clamping gear ring 2405 is rotatably connected to the outer surface of the hollow cylinder 2401 on the left side of the gear ring 2402 via a bearing. At least four handles 2406 are fixedly connected to the right side of the clamping gear ring 2405. The meshing of the first gear 2404 with the gear ring 2402 enables precise transmission of power from the first servo motor 2403. The servo motor drives the hollow cylinder 2401 to rotate synchronously and smoothly with the clamped workpiece. The rotation speed of the workpiece can be precisely controlled by adjusting the speed of the servo motor to adapt to different turning requirements. The clamping gear ring 2405 provides a power transmission carrier for the clamping action. The handle 2406 fixedly connected to the right side of the clamping gear ring 2405 makes it easy for the operator to manually rotate the clamping gear ring 2405. The operation is convenient, and the multi-handle layout can make the operator apply force evenly and prevent the clamping gear ring 2405 from deviating when rotating.

[0025] In one embodiment of the present invention, at least three second gears 2407 are rotatably connected to the outer surface of the hollow cylinder 2401 on the left side of the clamping gear ring 2405. Each of the three second gears 2407 has a clamping threaded rod 2408 threadedly connected to its center. The three second gears 2407 mesh with the left side of the clamping gear ring 2405. The ends of the three clamping threaded rods 2408 extend into the interior of the hollow cylinder 2401 and are fixedly connected to a top sleeve 2409. The second gears 2407 can precisely mesh with the clamping gear ring 2405 to achieve synchronous power transmission. The evenly distributed arrangement of multiple gears ensures balanced clamping force. The clamping threaded rods 2408, each threadedly connected to its center, can synchronously extend and retract when the second gears 2407 rotate, thereby driving the top sleeve 2409 to clamp the inner wall of the workpiece, adapting to… The clamping requirements of liquid cooling joints with different inner diameter expansion and contraction patterns are as follows: Three second gears 2407 mesh with the left side of the clamping gear ring 2405. Rotating the clamping gear ring 2405 synchronously drives the three second gears 2407 to rotate, achieving synchronous adjustment of the three clamping threaded rods 2408. This ensures balanced force on the workpiece clamping and prevents workpiece displacement. The top sleeve 2409 is made of soft and wear-resistant material, increasing the contact area with the inner wall of the workpiece, improving clamping stability, and preventing damage to the inner wall of the workpiece. The threads of the three clamping threaded rods 2408 are all trapezoidal threads. Trapezoidal threads have the advantages of strong load-bearing capacity and good self-locking performance. They will not rotate under external force, ensuring the workpiece remains stable after clamping and preventing workpiece loosening due to threaded rod rotation during processing, thus ensuring processing accuracy.

[0026] In one embodiment of the present invention, the tool feeding assembly 25 includes a mounting plate 2501. Electric telescopic rods 2502 are provided at each of the four corners of the bottom of the mounting plate 2501. All four electric telescopic rods 2502 are fixedly mounted above the base plate 1, and their output ends are fixedly connected to the bottom surface of the mounting plate 2501. Plates 2503 are fixedly connected to both the left and right sides of the upper surface of the mounting plate 2501. A first fixing seat 2504 is fixedly connected above the left plate 2503. The symmetrical arrangement of the four electric telescopic rods 2502 provides support for the mounting plate 2501. Balanced support and lifting power ensure smooth and precise lifting of the mounting plate 2501, and synchronously drive the vertical lifting of the mounting plate 2501 to achieve precise adjustment of the height of the second tool 2510, adapting to the milling needs of different parts of the liquid cooling connector; the plate 2503 provides a stable mounting carrier for components such as the first fixed seat 2504 and the second pad 2505 above; the first fixed seat 2504 fixedly connected above the left plate 2503 provides precise guidance and support for the sliding of the connecting rod 2509, ensuring that the connecting rod 2509 moves smoothly without deviation.

[0027] In one embodiment of the present invention, two sets of second pads 2505 are fixedly connected between two plates 2503. A third guide rail 2506 is fixedly connected above each set of second pads 2505. A second fixed seat 2508 is slidably connected above the two sets of third guide rails 2506 via a sliding block. A connecting rod 2509 is fixedly connected inside the second fixed seat 2508. The left end of the connecting rod 2509 is slidably connected to the inside of the first fixed seat 2504, and a second cutter 2510 is detachably connected to the left end of the connecting rod 2509. The second pads 2505 can raise the installation height of the third guide rails 2506, facilitating precise docking of the second cutter 2510 with the workpiece, and simultaneously providing a fixed support for the upper part of the plate. The two sets of third guide rails 2506 provide a flat and solid mounting base; the two sets of third guide rails 2506 can provide precise guidance for the left and right movement of the second fixed seat 2508, ensuring that the second fixed seat 2508 moves smoothly and without deviation, and ensuring the accuracy of milling tool feeding; the left end of the connecting rod 2509 is slidably connected to the inside of the first fixed seat 2504, which can further improve the stability and accuracy of the movement of the second fixed seat 2508 and avoid tool shaking during milling; the detachable second tool 2510 makes it easy to replace different types and functions of tools according to processing needs, improving the adaptability of the equipment for milling processing, and enabling multi-directional and multi-process milling processing of liquid-cooled joints.

[0028] In one embodiment of the present invention, a second movable threaded rod 2507 is rotatably connected between the middle of two plates 2503. The second movable threaded rod 2507 is fixedly connected to the bottom surface of the second fixed seat 2508 through a threaded seat. At least one plate 2503 has a second servo motor 2511 fixedly installed on its side to drive the rotation of the second movable threaded rod 2507. The threaded transmission has the advantages of high transmission accuracy and good self-locking, and can accurately convert the rotational power of the second movable threaded rod 2507 into the left and right linear movement of the second fixed seat 2508 along the third guide rail 2506, so as to realize the precise adjustment of the milling feed of the second tool 2510 and ensure the dimensional accuracy of the milling process. The second servo motor 2511 has the advantages of adjustable speed and high positioning accuracy, and can accurately control the rotation angle and speed of the second movable threaded rod 2507, thereby accurately controlling the feed speed and feed distance of the second tool 2510, adapting to different milling accuracy requirements, and improving the quality and efficiency of milling.

[0029] The working principle and workflow of this device are as follows: S1: According to the design requirements of the liquid-cooled joint, the external machining dimensions, drilling diameter, reaming size, dressing accuracy, tool movement speed, workpiece rotation speed, cutting position parameters, and the required machining program are preset through the equipment control system. The right end of the cylindrical workpiece to be processed is manually inserted into the hollow cylinder 2401 of the clamping assembly 24 to ensure that the workpiece axis is aligned with the axis of the hollow cylinder 2401. The handle 2406 of the clamping gear ring 2405 is rotated to drive the clamping gear ring 2405 to rotate. The three second gears 2407 are driven to rotate synchronously through meshing. The second gears 2407 drive the clamping threaded rod 2408 to move inward, so that the three top clamping sleeves 2409 clamp the right end of the workpiece synchronously. The clamping cylinder 7 is activated to push the support plate 5 to move to the right along the first guide rail 4, so that the left end rotating block 6 is in contact with the center of the left end of the workpiece, forming a two-way support to prevent the workpiece from shaking during processing. S2: Start the third servo motor 26, drive the first moving threaded rod 18 to rotate, drive the moving plate 10 to move along the second guide rail 9 to the area above the workpiece to be processed, start the elevator 11, drive the lifting threaded rod 12 to move downward, drive the fixed plate 14 and the first tool 15 to descend, until the cutting edge of the first tool 15 is in contact with the initial cutting position of the outer surface of the workpiece, and the first guide rod 13 ensures that the descent process is smooth. S3: Start the first servo motor 2403, and drive the first gear 2404 to rotate through the output end. The first gear 2404 meshes with the gear ring 2402, driving the hollow cylinder 2401 and the clamped workpiece to rotate synchronously according to the preset parameters. The third servo motor 26 continuously drives the moving plate 10 to move laterally along the second guide rail 9. The first tool 15 moves with the moving plate 10 and turns the outer surface of the workpiece according to the preset size to process the outline of the liquid cooling connector. After the outline is processed, the elevator 11 drives the first tool 15 to rise and reset. The third servo motor 26 drives the moving plate 10 to move to the outside of the processing area to avoid interference with subsequent processes. S4: Manually replace the second tool 2510 with a drilling tool according to the processing steps, start the electric telescopic rod 2502, adjust the height of the mounting plate 2501 so that the axis of the second tool 2510 drilling tool is aligned with the axis of the preset hole position on the workpiece, start the second servo motor 2511 to drive the second moving threaded rod 2507 to rotate, causing the second fixed seat 2508 to move to the left along the third guide rail 2506, so that the drilling tool is close to the right end of the workpiece to be drilled, keep the workpiece rotating at the preset speed, and the second servo motor 2511 continues to drive the second fixed seat 2508 to move to the left. The drilling tool gradually drills into the workpiece, machining the initial channel according to the preset diameter. After drilling is completed, the second servo motor 2511 reverses and drives the second tool 2510 to exit the channel to the right, completing the drilling process. The second tool 2510 is manually replaced with a reaming tool, and the above axis alignment operation is repeated to align the reaming tool with the drilled channel. The second servo motor 2511 drives the reaming tool to move to the left to enlarge the hole along the initial channel, expanding the channel diameter to the preset size, removing burrs and errors generated during drilling. Then, the second servo motor 2511 reverses and drives the reaming tool to exit the workpiece. S5: Replace the second tool 2510 with a trimming tool. After it is back in place, the second servo motor 2511 drives the trimming tool to move slowly to the left to fine-tune the inner wall of the hole after the hole is enlarged, and trim the inside of the workpiece into the required shape. The movement trajectory of the second tool 2510 can be achieved by the up and down movement of the electric telescopic rod 2502 in combination with the feed of the second servo motor 2511. After trimming, the second servo motor 2511 reverses and drives the second tool 2510 to reset to the right. The electric telescopic rod 2502 adjusts the height of the mounting plate 2501 so that the second tool 2510 is away from the workpiece to avoid interference during cutting. S6: After the workpiece is processed, start the push cylinder 20 to push the tool holder 22 forward along the second guide rod 21, and drive the cutter 23 to approach the preset cutting position on the right end of the workpiece. Ensure that the cutting edge of the cutter 23 is perpendicular to the axis of the workpiece. Keep the workpiece rotating at a low speed. The push cylinder 20 continues to push the cutter 23 forward. The cutting edge gradually cuts into the workpiece until the processed liquid cooling connector is cut off from the raw material. During the cutting process, the second guide rod 21 ensures that the cutter 23 moves smoothly and avoids workpiece deformation or tilting of the cut surface. S7: After the cutting is completed, the push cylinder 20 retracts, driving the cutting blade 23 to reset backward; the first servo motor 2403 stops, the workpiece stops rotating, the handle 2406 of the clamping toothed ring 2405 rotates in the opposite direction, driving the top sleeve 2409 to move outward and release the workpiece; the clamping cylinder 7 retracts, driving the left end rotating block 6 to move to the left and disengage from the workpiece, and each servo motor drives the cutting tool, moving plate 10 and other components to reset to the initial position, preparing for the processing of the next workpiece.
