Description

Technical Field

[0001] This invention relates to the field of radiator manufacturing technology, specifically to an assembly device for a radiator core. Background Technology

[0002] Currently, aluminum radiators are widely used due to their excellent thermal conductivity. In the radiator manufacturing process, the assembly of the core is one of the key steps, especially for large-sized cores, where the assembly quality and efficiency directly affect the performance and production cost of the final product.

[0003] Currently available automatic and semi-automatic assembly machines are only suitable for assembling small cores. Large-size core assembly largely relies on traditional manual assembly machines or purely manual labor. However, these methods have the following drawbacks: The process is complicated and labor-intensive. For large-sized products, manual positioning, clamping and adjustment are extremely inconvenient and require a lot of physical exertion from the operators. Dimensional accuracy is difficult to guarantee. Manual assembly makes it difficult to accurately control key dimensions such as the length, width, height, and verticality of the core, which can easily lead to dimensional deviations and affect subsequent main body installation and product qualification rate. The difficulty and inefficiency of changing models are significant problems. When producing radiators of different specifications and models, adjusting the existing equipment is very time-consuming and may even require replacing the entire machine, resulting in low production efficiency and an inability to meet the market demand for rapid production switching.

[0004] Therefore, there is an urgent need to design a large-size core assembly machine that is easy to operate, convenient to adjust, accurate in positioning, and can improve assembly efficiency. Summary of the Invention

[0005] (a) Technical problems to be solved To address the shortcomings of existing technologies, this invention provides an assembly device for radiator cores, which has the advantage of being able to adapt to large-size radiators and solves the problem of not being able to automatically or semi-automatically assemble large-size radiators.

[0006] (II) Technical Solution To achieve the above-mentioned purpose of adapting to large-size heat sinks, the present invention provides the following technical solution: a heat sink core assembly device, including a base support and an assembly platform. The base support is an integral load-bearing foundation. The side of the assembly platform used for assembling the core is the front side. The base support is set on the back side of the assembly platform. The assembly platform is provided with an opening distance adjustment mechanism, a core width clamping mechanism, and a main plate auxiliary assembly mechanism. The assembly platform includes a central fixed plate, a movable plate, and a flipping plate. A movable plate is arranged on the left and right sides of the central fixed plate. A flipping plate is provided on the side of the movable plate away from the central fixed plate. The flipping plate and the movable plate are rotatably connected. An assembly plate is detachably installed on the flipping plate. The assembly plate is used to clamp the product with the core to be assembled. The opening distance adjustment mechanism adopts a structure that combines a large-range rigid transmission adjustment with a small-range rapid fine adjustment, which can simultaneously adjust the distance between the moving plate and the flipping plate and the central fixed plate, and change the distance between the mounting plates on the left and right flipping plates. The core width clamping mechanism includes an upper clamping cylinder disposed on the upper part of the assembly platform. The upper clamping cylinder can adjust the clamping width as required, thereby controlling the final width dimension of the core. The main piece auxiliary assembly mechanism can control the flipping plate to drive the assembly plate to flip to the rear of the assembly platform, so that sufficient operating space is reserved at both ends of the core for the installation of the main piece.

[0007] The opening distance adjustment mechanism includes a lead screw drive device and a transverse sliding lead screw. The two ends of the transverse sliding lead screw are fixed to the base bracket by the base support and are driven to rotate by the lead screw drive device. The back of the moving plate is provided with a moving plate support seat, which is set on the transverse sliding lead screw. When the transverse sliding lead screw rotates, the moving plate support seat drives the moving plate to move along the extension direction of the transverse sliding lead screw, adjusting the distance between it and the central fixed plate. The assembly plate has comb-shaped protrusions on the side facing the core to be assembled.

[0008] The flip plate is equipped with fine-tuning brackets on its upper and lower sides, and fine-tuning movable rods are provided on the fine-tuning brackets. The fine-tuning movable rods can move left and right along the rods provided on the fine-tuning brackets. The assembly plate is located on the side of the fine-tuning movable rod closer to the moving plate. The flip plate is equipped with a front-push cylinder on the side away from the moving plate. The front-push cylinder can push the fine-tuning movable rod to move along the extension direction of the rods provided on the fine-tuning brackets, changing the distance between the assembly plates on the left and right sides of the flip plate. At the same time, the fine-tuning movable rod is equipped with a laser rangefinder sensor for measuring the distance between the product to be assembled and the assembly plate.

[0009] The upper clamping cylinders are evenly distributed on the upper ends of the central fixed plate and the movable plate. Each upper clamping cylinder push rod has a push plate at its end. There is a thin film pressure sensor between the cylinder rod and the push plate. The cylinder rod is driven to push by the change of pressure value.

[0010] The central fixed plate and the movable plate are provided with vertically extending pressing rails. The back of the pressing rails is provided with a longitudinal sliding screw in the same direction as its extension. The upper pressing cylinder is movably connected to the longitudinal sliding screw. The longitudinal sliding screw is driven to rotate by a screw drive device, so that the upper pressing cylinder can adjust its vertical distance on the assembly platform along the extension direction of the longitudinal sliding screw.

[0011] The main body auxiliary assembly mechanism includes a front-mounted push cylinder and a side-rear push cylinder. The side-rear push cylinder is located on the back of the moving plate, and the end of the push rod of the side-rear push cylinder is hinged to the flipping plate. The push rod of the side-rear push cylinder is tilted upward towards the front of the assembly platform. After the core body is assembled and pressed, the front-mounted push cylinder retracts outward. At the same time as the assembly plate is retracted, the side-rear push cylinder also retracts, and the flipping plate can drive the assembly plate to rotate to the rear of the assembly platform.

[0012] A bushing is provided between the transverse sliding screw and the base support and the moving plate support. The bushing is annular and split in half, forming a semi-open shape. The base support and the moving plate support are divided into upper and lower parts along the horizontal diameter of the transverse sliding screw section and are connected and fastened through fixing holes.

[0013] The bushing has anti-rotation blocks arranged in a circular array on the contact surface with the base support and the movable plate support. The contact surface between the base support and the movable plate support and the bushing has grooves corresponding to the shape and position of the anti-rotation blocks. The two end faces of the bushing have flanges for dust prevention.

[0014] The movable plate support seats on the back of the movable plate are arranged in pairs, and the length of the bushing in the movable plate support seat is the width of the two movable plate support seats plus the distance between the two movable plate support seats in the same group.

[0015] The contact surfaces of the upper and lower parts of the bushing are rounded.

[0016] (III) Beneficial Effects Compared with the prior art, the present invention provides an assembly device for a radiator core, which has the following advantages: 1. The assembly equipment for this radiator core achieves a comprehensive improvement in stability, adaptability, and precision throughout the assembly process through multi-structure collaborative optimization. The frame-type base support, welded from steel profiles, possesses strong anti-deformation capabilities, providing stable load-bearing capacity and effectively avoiding stress deformation issues during the assembly of large-sized cores, ensuring the long-term stability of the assembly reference. The symmetrical moving plate structure, with the central fixed plate as the positioning reference, ensures the synchronicity of the adjustment actions on both sides, fundamentally preventing core assembly misalignment and significantly improving assembly coaxiality and consistency. The opening distance adjustment mechanism, composed of dual-rotating counter-rotating screws, enables synchronous opposite or backward movement of the two moving plates, accommodating the wide range of adjustment needs for cores of different lengths and specifications while maintaining rigid transmission stability during the assembly process. Combined with a fine-tuning structure consisting of a front-mounted propulsion cylinder, guide rod, and linear bearing, it can achieve assembly... The small-amplitude, precise adjustment of the spacing, combined with real-time numerical feedback from the laser rangefinder, forms a closed-loop control, effectively eliminating manual adjustment errors and further improving assembly positioning accuracy. The flip-up plate and quick-change assembly plate design can adapt to the clamping requirements of cores of different specifications, significantly improving equipment changeover efficiency and reducing tooling management costs. At the same time, the flip-up structure provides ample operating space for the main piece assembly, avoiding assembly interference and improving operational convenience and safety. The adjustable core width clamping mechanism at the top can precisely control the final width dimension of the core, ensuring compliance with product assembly dimensions. The overall modular structure design facilitates daily maintenance and repair, significantly reducing the skill threshold for equipment operation, effectively reducing manual labor intensity, and improving the yield rate and production efficiency of core assembly. Meanwhile, the symmetrical transmission and adjustment structure can balance the force on the equipment during operation and extend the service life of the equipment.

[0017] 2. The radiator core assembly equipment, through the cooperation of the upper clamping component, the longitudinal adjustment structure, and the main plate auxiliary assembly mechanism with dual cylinders, further improves the overall performance of radiator core assembly. The upper clamping cylinders are evenly distributed on the upper end of the corresponding plate, and the clamping force acts vertically on the core surface, eliminating core displacement and assembly misalignment caused by lateral force. With the addition of a long strip push plate to expand the contact range, the clamping force can be evenly distributed throughout the entire area, effectively preventing localized stress concentration from damaging the core components. The embedded thin-film pressure sensor can collect clamping pressure data in real time, and form a closed-loop control of clamping force based on signal feedback, making the clamping operation more in line with the pressure requirements of different cores, improving assembly protection and dimensional control accuracy. The vertically integrated clamping track provides a regular avoidance and limit guide for the cylinder's up and down adjustment. The longitudinal sliding screw and the transverse screw are orthogonally arranged, and the unified drive component enables flexible adjustment of the clamping cylinder's height position. This allows for clamping operations on cores of various heights, ensuring that the clamping force covers the entire height range of the core and broadening the equipment's versatility. The main piece auxiliary assembly mechanism adopts a combination design of front-mounted and side-rear-mounted cylinders. The double-hinged installation structure can adapt to changes in the rotation angle of the flipping plate, eliminating motion interference and jamming issues, ensuring smooth and stable flipping and adjustment movements. During operation, the front-mounted cylinder retracts first to avoid contact and compression between the assembly plate and the core, and then the side-rear-mounted cylinder pulls the flipping plate to rotate backward to make room. This efficiently opens up sufficient operating areas at both ends of the core, greatly reducing the operational difficulty of main piece installation. The overall adjustment, clamping, and flipping structures work together in an orderly and coherent manner, with a compact and reasonable structural layout and stable and reliable motion transmission. This not only optimizes the assembly operation process and reduces manual intervention and blind spots, but also continuously and stably ensures assembly quality, reduces the probability of component wear, extends the service life of various moving parts of the equipment, and effectively improves the overall assembly efficiency and equipment operation stability.

[0018] 3. The assembly equipment for this radiator core, through the combination of a semi-disassembled semi-ring bushing and an upper and lower split support structure, allows for rapid replacement of the bushing and maintenance of the internal transmission pair without disassembling the entire screw drive mechanism or removing the related components between the drive end and the support end of the machine. This significantly reduces equipment downtime and lowers the operational threshold and labor costs. The embedded, one-piece molded anti-rotation block structure between the bushing and the support seat achieves circumferential limiting without additional fasteners. Disassembly and assembly do not require additional removal of the limiting components, further improving maintenance efficiency. Simultaneously, it completely prevents circumferential movement of the bushing as the screw rotates, ensuring long-term stable transmission accuracy. The one-piece flanged structure at the bushing end effectively prevents dust, metal shavings, and other impurities from entering the transmission mating surface, reducing component wear and failure frequency, lowering the frequency of daily cleaning and maintenance, and also provides axial positioning during disassembly and assembly. No additional adjustment to the bushing axial position is required, improving the accuracy and efficiency of assembly and resetting. The design of double support seats on the back of the moving plate, combined with a full-length integrated bushing, increases the support span to prevent the moving plate from swaying and tipping over, ensuring assembly positioning accuracy. It also reduces the number of assembly points for vulnerable parts, reducing the workload of disassembly and calibration. At the same time, it ensures even force distribution, reducing the risk of lead screw deformation and lowering the frequency of subsequent calibration and maintenance. The rounded corner structure of the bushing mating surface prevents sharp edges from scratching operators during disassembly and assembly, improving the safety of maintenance operations. It also prevents sharp edges from bumping and rolling, ensuring precise bushing mating and reducing assembly rework rate. Combined with the wear-resistant and self-lubricating bushing material, it reduces transmission friction loss, further extending the service life of the transmission pair and reducing the frequency of equipment maintenance. It works in synergy with the overall machine opening distance adjustment mechanism to ensure long-term stable transmission accuracy for the large-range adjustment and precise fine-tuning of the core assembly, improving the overall operational reliability of the equipment.

[0021] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] Please see Figures 1-4 The radiator core assembly equipment includes a base support 1 and an assembly platform 2. The base support 1 adopts a frame structure welded from structural steel, providing a stable load-bearing foundation for the entire equipment and effectively resisting stress deformation during the assembly of large-sized cores. The assembly platform 2 has its front side for assembling the core, and the base support 1 is located on the back side of the assembly platform 2. The assembly platform 2 is equipped with an opening distance adjustment mechanism, a core width clamping mechanism, and a main plate auxiliary assembly mechanism. The assembly platform 2 includes a central fixing plate 21, a moving plate 22, and a flipping plate 221. The central fixing plate 21 is fixedly installed in the middle of the base support 1 as the core assembly... The reference positioning surface is equipped with a movable plate 22 symmetrically arranged on its left and right sides to ensure the symmetry of the adjustment action on both sides and avoid the core assembly from being misaligned. The movable plate 22 has a flip plate 221 on the side away from the central fixed plate 21. The flip plate 221 and the movable plate 22 are rotatably connected by a hinge structure. An assembly plate 321 is detachably installed on the flip plate 221, which can quickly change the matching model according to different core specifications, improving the equipment changeover efficiency. The assembly plate 321 has a positioning structure that matches the edge of the core to stabilize the core product to be assembled and prevent the core from moving during the assembly process. The opening distance adjustment mechanism adopts a structure that combines large-range rigid transmission adjustment with small-range rapid fine adjustment. It can simultaneously adjust the horizontal distance between the moving plate 22 and the flip plate 221 and the central fixed plate 21, thereby changing the relative distance between the mounting plates 321 on the left and right flip plates 221. It can adapt to radiator cores of different lengths and specifications. It can not only meet the large-range adjustment requirements of large-size cores, but also achieve precise fine adjustment during the assembly process, ensuring the positioning accuracy of the core length direction.

[0023] The core width clamping mechanism includes an upper clamping cylinder 31 disposed on the upper end of the assembly platform 2. The upper clamping cylinder 31 can adjust the clamping width as required, thereby controlling the final width dimension of the core. The main piece auxiliary assembly mechanism can control the flip plate 221 to drive the assembly plate 321 to flip to the rear side of the assembly platform 2, so that sufficient operating space is reserved at both ends of the core for the installation of the main piece.

[0024] The opening gap adjustment mechanism includes a lead screw drive device 41 and a transverse sliding lead screw 42. The transverse sliding lead screw 42 is a double lead screw arranged symmetrically in parallel, with the two lead screws rotating in opposite directions, which can ensure that the two moving plates 22 on both sides move synchronously towards or away from each other. The two ends of the transverse sliding lead screw 42 are fixed to the base bracket 1 by the base support 11. The ends of the transverse sliding lead screw 42 are connected to the output end of the lead screw drive device 41 through a coupling, and are driven to rotate by the lead screw drive device 41. The lead screw drive device 41 can be a manually controlled handwheel structure. Alternatively, a servo motor can be used for control. The base support 11 is bolted to the left and right ends of the base bracket 1, providing stable rotational support for the lead screw. The back of the movable plate 22 is bolted with a movable plate support 12, which is mounted on the transverse sliding lead screw 42. When the transverse sliding lead screw 42 rotates, the movable plate support 12 drives the movable plate 22 to move along the extension direction of the transverse sliding lead screw 42, precisely adjusting the distance between it and the central fixed plate 21 to adapt to core products of different lengths. (See reference...) Figures 9-10 The assembly plate 321 has comb-shaped protrusions on the side facing the core to be assembled. The protrusions are evenly spaced along the assembly plate 321. The comb-shaped protrusions can be precisely embedded into the groove formed by the side plate and the heat sink tube in the heat sink core, so as to avoid damage to the heat sink tube during the clamping process.

[0025] The flip plate 221 is symmetrically bolted to the upper and lower sides with fine-tuning brackets 3221. A guide rod parallel to the transverse sliding screw 42 is fixed on the fine-tuning bracket 3221. The two ends of the guide rod are limited and fixed by bearing seats, providing precise guidance for component movement. The fine-tuning bracket 3221 is equipped with a fine-tuning movable rod 322. The upper and lower ends of the fine-tuning movable rod 322 are mounted on the guide rod via linear bearings, allowing for smooth left-right linear movement along the guide rod on the fine-tuning bracket 3221, preventing skewing or jamming during movement. The assembly plate 321 is vertically bolted to the end face of the fine-tuning movable rod 322 near the moving plate 22, ensuring the verticality of the assembly plate 321 and improving the core clamping accuracy. A front-mounted push cylinder 32 is fixedly mounted on the end face of the flip plate 221 away from the moving plate 22 via a cylinder seat. The push rod of the front-mounted push cylinder 32 extends toward the moving plate 22. The front-mounted push cylinder 32 can push the fine-tuning rod 322 to move along the extension direction of the guide light rod, thereby driving the assembly plate 321 to move synchronously. This enables small-amplitude precise fine-tuning of the spacing between the assembly plates 321 on the left and right flip plates 221. At the same time, a laser range sensor is fixedly mounted on the fine-tuning rod 322 via a bracket. The detection end of the laser range sensor faces the core to be assembled, and it can measure the distance between the product to be assembled and the assembly plate 321 in real time, providing accurate numerical feedback for spacing adjustment, ensuring adjustment accuracy, and avoiding errors from manual adjustment.

[0026] The upper clamping cylinders 31 are evenly fixed to the upper ends of the central fixed plate 21 and the moving plate 22 via cylinder mounting seats. The extension direction of the push rods of all upper clamping cylinders 31 is consistent and perpendicular to the front of the assembly platform 2, ensuring that the clamping force acts perpendicularly on the core surface and avoiding core displacement caused by component force. The end of the push rod of each upper clamping cylinder 31 is connected to a push plate mounting seat by thread. A long strip push plate is fastened to the push plate mounting seat by bolts, which can increase the contact area with the core, so that the clamping force is evenly distributed and avoids excessive local stress that damages the core. A thin film pressure sensor is embedded between the cylinder rod and the push plate mounting seat. The detection surface of the thin film pressure sensor is in close contact with the end of the push rod and the push plate mounting seat, which can detect the pressure value change in real time during the clamping process and feed the pressure signal back to the control system. The change of pressure value accurately drives the extension and retraction of the cylinder rod to achieve closed-loop control of the clamping degree.

[0027] Both the central fixed plate 21 and the movable plate 22 have vertically extending clamping rails 101 on their front sides. The clamping rails 101 have a through-slot structure, providing clearance and guiding limit for the movement of the upper clamping cylinder 31. A longitudinal sliding screw 43 with the same extension direction is mounted on the back of the clamping rails 101 through a bearing seat. The axis of the longitudinal sliding screw 43 is perpendicular to the axis of the transverse sliding screw 42. A screw nut seat is fixedly connected to the back of the cylinder mounting seat of the upper clamping cylinder 31. The screw nut seat is connected to the cylinder mounting seat through the clamping rails 101. The transmission nut inside the lead screw nut seat forms a threaded transmission engagement with the longitudinal sliding lead screw 43. The end of the longitudinal sliding lead screw 43 is connected to the output end of the lead screw drive device 41 through a coupling. The lead screw drive device 41 drives it to rotate, and through the threaded transmission, it drives the lead screw nut seat to move up and down. This allows the upper clamping cylinder 31 to adjust its vertical position on the assembly platform 2 along the extension direction of the longitudinal sliding lead screw 43, adapting to the clamping requirements of cores of different heights and ensuring that the clamping force can be evenly applied to the entire height direction of the core, thereby improving the clamping effect and the applicability of the equipment.

[0028] See Figures 3-4 The main assembly auxiliary mechanism includes a front-mounted push cylinder 32 and a side-rear push cylinder 33. The cylinder body of the side-rear push cylinder 33 is hinged to the back of the moving plate 22 via a double-ear hinge seat, and moves laterally synchronously with the moving plate 22. The end of the push rod of the side-rear push cylinder 33 is hinged to the flipping plate 221. The double-hinged structure can adapt to the angle changes during the rotation of the flipping plate 221, avoid cylinder jamming, and ensure smooth flipping action. The push rod of the side-rear push cylinder 33 is inclined upward towards the front of the assembly platform 2, and its inclination angle is adapted to the rotation stroke of the flipping plate 221, which can be used to... The push rod extends to push the flip plate 221 to maintain a working position flush with the moving plate 22, ensuring the clamping and positioning accuracy of the assembly plate 321. After the core body is assembled and pressed, the front push cylinder 32 retracts outward, driving the fine adjustment rod 322 and the assembly plate 321 to retract away from the core, avoiding interference with the core in subsequent flipping actions. At the same time, the side and rear push cylinder 33 retracts synchronously, pulling the flip plate 221 to rotate around the hinge axis to the rear of the assembly platform 2, thereby driving the assembly plate 321 to rotate synchronously to the rear of the assembly platform 2 to avoid interference, leaving sufficient operating space at both ends of the core.

[0029] See Figures 5-7The transverse sliding screw 42 is provided with bushings 111 between its mating surfaces and the base support 11 and the moving plate support 12. The bushings 111 are made of wear-resistant, self-lubricating material, which effectively reduces friction and wear on the mating surfaces, improves transmission accuracy and extends the service life of the mechanism. The inner wall of the bushing 111 is machined with an internal thread that perfectly matches the external thread profile and pitch of the transverse sliding screw 42, forming a complete threaded transmission pair with the transverse sliding screw 42. The bushing 111 is generally annular in shape and is split in half axially to form two semi-annular structures, creating a semi-open shape for easy installation. Disassembly and replacement maintenance can be completed without disassembling the entire lead screw transmission mechanism, reducing the difficulty of equipment maintenance. The base support 11 and the movable plate support 12 are both divided into upper and lower halves along the horizontal diameter direction of the cross section of the transverse sliding lead screw 42. The joint of the two halves is provided with a fixing hole 112 with internal thread. The two halves can be fastened together by passing bolts through the fixing hole 112. This split structure facilitates the assembly of the support, lead screw and bushing. At the same time, the fit clearance between the bushing and the lead screw can be adjusted by the bolt preload to ensure the stability and accuracy of the transmission.

[0030] The bushing 111 has multiple anti-rotation blocks 1111 arranged circumferentially on its outer cylindrical surface where it contacts the base support 11 and the movable plate support 12. Each anti-rotation block 1111 is a rectangular protrusion integrally formed with the bushing 111. The inner walls of the base support 11 and the movable plate support 12, which are in contact with the bushing 111, have grooves corresponding to the shape and position of the anti-rotation blocks 1111. The anti-rotation blocks 1111 are fitted into these grooves, effectively limiting the relative rotation between the bushing 111 and the support, and preventing the bushing from rotating under the influence of the base support 111. The circumferential movement caused by the rotation of the lead screw ensures the stable performance of the bushing's wear resistance and improves transmission stability. The bushing 111 has radially outwardly extending flanges 1112 integrally formed on both end faces. The outer diameter of the flanges 1112 is larger than the diameter of the inner hole of the support seat, which can completely cover the fit gap between the bushing and the inner hole of the support seat, preventing external dust, metal shavings and other impurities from entering the mating surface and the lead screw transmission pair. This avoids impurities from aggravating component wear and affecting transmission accuracy, providing good dust protection and extending the service life of the mechanism.

[0031] See Figure 5 and Figure 8The moving plate support seats 12 on the back of the moving plate 22 are arranged in pairs along the axis of the transverse sliding screw 42. The double support structure can increase the support span between the moving plate 22 and the transverse sliding screw 42, improve the stability of the moving plate 22 during translation, avoid the moving plate from swaying or overturning, and ensure the positioning accuracy of the assembly plate 321. In addition, the bushing 111 in the moving plate support seat 12 adopts a continuous integrated structure. The total length of the bushing 111 is the axial width of the two moving plate support seats 12 plus the interval distance between the two moving plate support seats 12 in the same group. The continuous bushing design can further improve the support stability and facilitate the distribution of pressure on the screw, avoiding the concentration that would cause the screw to bend and affect the transmission.

[0032] The edges of the mating contact surfaces of the upper and lower parts of the bushing 111 are provided with rounded corners. On the one hand, this can prevent the sharp edges of the bushing mating surfaces from scratching the operators and improve the operational safety during assembly and maintenance. On the other hand, it can prevent the sharp edges from bumping or curling during assembly, ensuring that the two semi-ring bushings can be accurately mated and fitted, reducing wear on the lead screw.

[0033] Working principle: This application describes a special assembly machine developed for large-size aluminum heat sink cores with a maximum core height of 2100mm. The base bracket 1 serves as the overall load-bearing foundation. Through the coordinated operation of the mechanical transmission adjustment mechanism, pneumatic actuators, and sensing feedback unit or manual fine-tuning unit, it achieves precise positioning and clamping assembly of large-size heat sink cores of different specifications. At the same time, it integrates main plate installation assistance and packaging pre-processing functions, simplifying production processes and improving assembly accuracy and production efficiency. The core functional structure of the equipment includes an opening distance adjustment mechanism, a core width clamping mechanism, and a main plate auxiliary assembly mechanism. When the opening distance adjustment mechanism is adjusted significantly, the screw drive device 41 drives the transverse sliding screw 42 to rotate, so that the moving plate support 12 drives the moving plate 22 to move on the transverse sliding screw 42, changing the distance between the mounting plates 321 set on the left and right moving plates 22. If the opening and closing is small, the front push cylinder 32 pushes the mounting plate 321 for fine adjustment. A laser range sensor can be set on the side of the moving plate 22. The specific opening and closing size to be adjusted is based on the distance measured by the laser range sensor. The core width clamping mechanism includes an upper clamping cylinder 31 set on the upper end of the assembly platform 2. The upper clamping cylinders 31 are evenly distributed on the central fixed plate 21 and the moving plate 22. Each upper clamping cylinder 31 has a push plate at the end of its push rod. There is a thin film pressure sensor between the cylinder rod and the push plate. The cylinder rod is driven by the change of pressure value, and the clamping width can be adjusted according to the requirements, thereby accurately controlling the final width dimension of the core and ensuring product accuracy. The main body auxiliary assembly mechanism includes a front-mounted push cylinder 32 and a side-rear push cylinder 33. A flip plate 221 is provided on the side of the moving plate 22 away from the base bracket 1. The flip plate 221 and the moving plate 22 are hinged together by a hinge. The side-rear push cylinder 33 is provided on the back of the moving plate 22. The end of the push rod of the side-rear push cylinder 33 is hinged to the flip plate 221. The side-rear push cylinder 33 is tilted outward towards the front. After the core body is assembled and pressed, the front-mounted push cylinder 32 retracts outward. At the same time as the assembly plate 321 is retracted, the side-rear push cylinder 33 also retracts, so that the flip plate 221 drives the assembly plate 321 to rotate to the rear. This can leave enough operating space at both ends of the core for the installation of the main body.
