Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of assembly, and in particular to a press-in mechanism for adapting a heat dissipation device damping rotary pin shaft. BACKGROUND

[0002] The damping rotary pin shaft is a key connecting piece in the heat dissipation device maintenance cavity structure, and is mainly applied to the rotary connecting part of the heat dissipation device maintenance window cover and the shell. In the daily use and maintenance process of the heat dissipation device, the maintenance window cover needs to be frequently opened and closed to realize the maintenance, cleaning or troubleshooting of the internal components, and the damping rotary pin shaft can provide smooth buffering force for the rotation of the maintenance window cover through its damping characteristics, so as to avoid the rapid opening and closing of the window cover due to gravity or external force impact, reduce the collision and wear between components, prolong the service life of the heat dissipation device, and enable the operator to more conveniently control the opening angle of the window cover, thereby improving the safety and comfort of the maintenance operation.

[0003] In the production and assembly process of the heat dissipation device, the press-in of the damping rotary pin shaft is a key process for ensuring the normal function of the heat dissipation device maintenance cavity. The traditional damping rotary pin shaft press-in method mainly relies on an oil press or a punch to realize one-to-one press-in assembly with a special mold tool. Such equipment usually has a large floor area, and the space layout of the plant site is strictly required, so a larger operation area needs to be specially planned, thereby increasing the use cost of the production site.

[0004] Meanwhile, the operation of the oil press and the punch requires higher professional skills of the operator, and the operator needs to undergo systematic training to master the skills such as operation specification, pressure adjustment and mold calibration of the equipment, thereby not only increasing the human training cost, but also increasing the production risk caused by improper operation. In addition, the design and production of the special mold tool need to be customized for a specific model of the heat dissipation device and the damping rotary pin shaft, which not only has high investment cost, but also has a long production cycle. When a new product needs to be trial-produced or the product model needs to be replaced, the mold needs to be redesigned and produced, which seriously restricts the trial-production progress and production flexibility of the new product.

[0005] However, the inventors have found that at least the following technical problems exist in the related art: the traditional heat dissipation device damping rotary pin shaft press-in relies on an oil press or a punch with a special mold, which has a large equipment floor area, strict site requirements, high production cost and long production cycle of the special mold, thereby resulting in low trial-production efficiency of new products, poor equipment versatility and inability to flexibly adapt to the press-in requirements of different models of products. SUMMARY

[0006] An object of the present application is to provide a press-in mechanism for adapting a heat dissipation device damping rotary pin shaft, at least to solve the above problems.

[0007] To achieve the above object, some embodiments of the present application provide a press-in mechanism for adapting a heat dissipation device damping rotary pin shaft, comprising:

[0008] The stand comprises a first horizontal plate, a second horizontal plate, a first vertical plate and a second vertical plate;

[0009] The push cylinder is arranged on the first horizontal plate;

[0010] The connecting rod is rotationally connected with the first vertical plate and / or the second vertical plate of the stand, and the first end of the connecting rod is rotationally connected with the telescopic rod of the push cylinder;

[0011] The pressing device comprises a sliding rail and a sliding block in sliding connection, and the sliding rail is arranged on the second horizontal plate of the stand;

[0012] The second horizontal plate of the stand is configured with a through hole, the second end of the connecting rod is arranged in the through hole, and under the action of the telescopic rod of the push cylinder, the second end of the connecting rod abuts against the sliding block of the pressing device and pushes the sliding block to move, so that the sliding block pushes the damping rotary pin shaft to be inserted into the housing of the radiator.

[0013] Compared with the related art, in the scheme provided by the embodiments of the present application, the push cylinder drives the sliding block of the pressing device to move through the connecting rod, which converts linear motion into precise pressing action, replacing the rigid driving mode of the traditional special mold; the sliding connection between the sliding rail and the sliding block ensures the stability of the pressing process, avoids the stress deviation of the damping rotary shaft pin, and improves the assembly precision. The overall structure realizes the collaborative work of each component through modular design, breaks away from the dependence of traditional equipment on special molds, reduces the requirement for the professional skills of operators, reduces the equipment floor space at the same time, and adapts to the production needs of different scenes.

[0044] It should be noted that the embodiments in the present disclosure and the features in the embodiments can be combined with each other without conflict.

[0045] In combination with Figures 1 to 8 As shown in the drawings, the present disclosure provides a press-in mechanism for adapting a heat dissipation device to a damping rotary pin shaft, comprising a stand 10, a push cylinder 20, a connecting rod 30 and a pressing device.

[0046] The stand 10 comprises a first horizontal plate 101, a second horizontal plate 102, a first vertical plate 103 and a second vertical plate 104; the push cylinder 20 is arranged on the first horizontal plate 101; the connecting rod 30 is rotationally connected with the first vertical plate 103 and / or the second vertical plate 104 of the stand 10, and the first end is rotationally connected with the telescopic rod of the push cylinder 20; the pressing device comprises a sliding rail and a sliding block 403 in sliding connection, and the sliding rail is arranged on the second horizontal plate 102 of the stand 10; wherein the second horizontal plate 102 of the stand 10 is configured with a through hole 1021, the second end of the connecting rod 30 is arranged in the through hole 1021, and under the action of the telescopic rod of the push cylinder 20, the second end of the connecting rod 30 abuts against the sliding block 403 of the pressing device and drives the sliding block 403 to move, so that the sliding block 403 drives the damping rotary pin shaft 300 to be inserted into the housing of the heat dissipation device 400.

[0047] The press-in mechanism for adapting the heat dissipation device 400 to the damping rotary pin shaft 300 provided by the present disclosure drives the sliding block 403 of the pressing device to move through the connecting rod 30 of the push cylinder 20, which converts linear motion into precise press-in action, replacing the rigid driving mode of the traditional special mold. The sliding connection between the sliding rail and the sliding block 403 ensures the stability of the press-in process, avoids the stress deviation of the damping rotary shaft pin, and improves the assembly precision. The overall structure realizes the collaborative work of each component through modular design, breaks away from the dependence on special mold of traditional equipment, reduces the requirement for professional skills of operators, reduces the equipment floor space, and adapts to the production needs of different scenes.

[0048] Optionally, it further comprises a jacking cylinder 60, the telescopic rod of which is connected with the first horizontal plate 101 of the stand 10, and under the driving of the telescopic rod of the jacking cylinder 60, the stand 10 moves up and down along the axial direction of the jacking cylinder 60.

[0049] The jacking cylinder 60 drives the stand 10 to move up and down, which can flexibly adjust the working space height and facilitate the taking and placing of the heat dissipation device 400; solves the problem that the traditional oil press or punch is not convenient for taking and placing the heat dissipation device 400 due to the fixed structure, and greatly improves the operation convenience.

[0050] Optionally, the maintenance window cover is mounted on the housing of the heat dissipation device 400 through the damping rotary pin shaft 300, and the maintenance window cover is rotationally connected with the housing.

[0051] The damping rotating pin shaft 300 is precisely inserted into the shell of the radiator 400 through the pressing mechanism, realizing the rotating connection of the maintenance window cover and the shell, ensuring the normal opening and closing function of the maintenance cavity of the radiator 400, and guaranteeing the structural integrity and functionality of the radiator 400 assembly.

[0052] Optionally, the stop block 50 is arranged on the second transverse plate 102 of the stand 10 and is arranged opposite to the sliding block 403. In the case that the sliding block 403 is pushed to move by the second end of the connecting rod 30, the shell of the radiator 400 to be installed with the damping rotating pin shaft 300 abuts against the stop block 50, the damping rotating pin shaft 300 is located between the sliding block 403 and the stop block 50, the sliding block 403 moves towards the stop block 50, the sliding block 403 applies pressure to the damping rotating pin shaft 300, and the damping rotating pin shaft 300 is inserted into the shell of the radiator 400.

[0053] The opposite arrangement of the stop block 50 and the sliding block 403 forms a stable pressing reference, so that the damping rotating pin shaft 300 is located in the limited space between the sliding block 403 and the stop block 50 in the pressing process, avoiding lateral deviation of the damping rotating pin shaft 300 under the pressure. The abutting relationship between the shell of the radiator 400 and the stop block 50 provides rigid support for the pressing action, ensuring that the pressure applied by the sliding block 403 can be efficiently converted into the insertion power of the damping rotating pin shaft, solving the problem of insufficient pressing depth caused by unstable support in the traditional pressing method. The arrangement of the stop block 50 also simplifies the positioning operation of the operator, without the need to repeatedly calibrate the position of the radiator 400, reducing the operation difficulty, and ensuring the consistency of the pressing position of each radiator 400 in batch production.

[0054] Optionally, the sliding block 403 and the stop block 50 form a jaw, and in the use process, the damping rotating pin shaft 300 is located in the jaw, and the sliding block 403 pushes the damping rotating pin shaft 300 to move towards the stop block 50.

[0055] The sliding block 403 and the stop block 50 form a jaw structure, which limits the damping rotating pin shaft 300 in the jaw, so that the pin shaft is subjected to concentrated force and stable direction in the pressing process, preventing the pin shaft from being skewed or falling off, further guaranteeing the accuracy of the pressing position and simplifying the pre-positioning requirement of the pin shaft in the operation process.

[0056] Optionally, the pressing device includes symmetrically arranged first sliding rails 401 and second sliding rails 402, and the first sliding rails 401 and the second sliding rails 402 are both configured with sliding grooves; the opposite sides of the sliding block 403 are slidably connected in the sliding grooves.

[0057] The first slide rail 401 and the second slide rail 402 arranged symmetrically provide double-side guiding support for the slider 403, ensuring that the slider 403 remains stable and horizontal during movement, avoiding deviation or jam caused by unilateral force. The symmetric structure makes the force on the slider 403 more balanced, efficiently converting the driving force of the push cylinder 20 into pressure, avoiding energy loss and improving the transmission efficiency of the mechanism.

[0058] Optionally, the slider 403 is configured with a pressing part 4031 protruding from the lower edge of the slide rail, that is, the pressing part 4031 protrudes from the accommodating cavity enclosed by the first slide rail 401 and the second slide rail 402, so as to be inserted into the space on the top of the heat sink 400 and press the damping rotary pin shaft 300.

[0059] The design of the pressing part 4031 of the slider 403 protruding from the accommodating cavity enables it to be accurately inserted into the narrow space on the top of the heat sink 400, and to press the damping rotary pin shaft 300 in a targeted manner according to the installation position of the damping rotary pin shaft 300, solving the problem of inaccurate force exertion caused by space limitation in the conventional pressure insertion mechanism. The targeted design of the pressing part 4031 reduces the contact interference with other parts of the heat sink 400, avoiding scratching or damaging the surface of the heat sink 400 during pressure insertion. The protruding pressing part 4031 enables the pressure to be concentrated on the end of the damping rotary pin shaft 300, improving the pressure insertion efficiency and ensuring that the pin shaft is quickly and accurately inserted into place, which is particularly suitable for the assembly of heat sinks 400 with complex structures and compact spaces.

[0060] Optionally, the stop block 50 is configured with a stop part 501 matched with the pressing part 4031, and the side of the stop part 501 facing the pressing part 4031 is configured with an avoiding groove 502, so that the damping rotary pin shaft 300 can pass through the heat sink shell and protrude from the other side of the heat sink shell.

[0061] The matching design of the stop part 501 of the stop block 50 and the pressing part 4031 ensures the accurate correspondence between the force exertion point and the force receiving point during pressure insertion, ensuring that the pressure is transmitted to the damping rotary pin shaft 300 in the axial direction.

[0062] The avoiding groove 502 of the stop part 501 provides a space for the damping rotary pin shaft 300 to pass through the shell and protrude from the shell by a certain length, allowing the end of the damping rotary pin shaft 300 to protrude from the heat sink 400 shell and meet the size requirements of the heat sink 400 assembly, avoiding insufficient pressure insertion depth caused by limitation on the other side of the shell.

[0063] Optionally, the bottom of the stop block 50 is also configured with a limiting part 503, and the limiting part 503 is arranged perpendicularly to the stop part 501. When the heat sink 400 abuts against the stop block 50, the limiting part 503 is located above and close to the shell of the heat sink 400, ensuring that the insertion position of the damping rotary pin shaft 300 corresponds to the position of the avoiding groove 502 of the stop part 501.

[0064] The limiting portion 503 at the bottom of the stop block 50 is vertically arranged with the stop portion 501 to form a secondary positioning constraint from above the housing of the heat sink 400, ensuring that the housing position of the damping rotary pin shaft 300 to be installed is accurately aligned with the stop portion 501 and the avoidance groove 502, solving the problem of position deviation caused by slight shaking of the heat sink 400 in the traditional positioning mode.

[0065] The design of the limiting portion 503 close to the housing of the heat sink 400 enhances the stability of the overall positioning, effectively resisting the reaction force exerted by the slider 403 during the pressing process, preventing the heat sink 400 from shifting. This double positioning structure reduces the requirement for the precision of the operator placing the heat sink 400, even if there is a slight deviation in the placement of the heat sink 400, the limiting portion 503 can correct it, ensuring consistency in mass production.

[0066] Optionally, the first slide rail 401 and the second slide rail 402 are detachably connected to the bottom surface of the second horizontal plate 102.

[0067] The first slide rail 401 and the second slide rail 402 are detachably connected to the second horizontal plate 102, facilitating the replacement, maintenance or replacement of different specifications of slide rails to adapt to different sliders 403, reducing the cost of mechanism maintenance, enhancing the flexibility and expandability of the structure.

[0068] Optionally, the bottom surface of the second horizontal plate 102 is configured with a receiving groove 1022 for mounting the stop block 50.

[0069] The receiving groove 1022 at the bottom surface of the second horizontal plate 102 provides installation and positioning space for the stop block 50, ensuring accurate and stable installation position of the stop block 50, avoiding displacement of the stop block 50 under pressure during pressing, and ensuring the reliability of the supporting action of the stop block 50 during the pressing process.

[0070] The receiving groove 1022 at the bottom surface of the second horizontal plate 102 provides accurate installation and positioning reference for the stop block 50, ensuring accurate position of the stop block 50 during assembly, avoiding incorrect pressing position caused by installation deviation of the stop block 50. The structure of the receiving groove 1022 forms a circumferential constraint on the stop block 50, resisting the reaction force transmitted by the slider 403 during the pressing process, preventing the stop block 50 from loosening or shifting, and ensuring the stability of the pressing action.

[0071] Optionally, the stop block 50 can be detachably connected to the bottom of the receiving groove 1022 by screws. Optionally, the stop block 50 is connected to the receiving groove 1022 by clamping.

[0072] Optionally, the second end of the connecting rod 30 is provided with a roller 303, so that the roller 303 abuts against and pushes the slider 403 to move when the connecting rod 30 rotates.

[0073] The roller 303 at the second end of the connecting rod 30 converts the sliding friction between the connecting rod 30 and the slider 403 into rolling friction, significantly reducing the friction therebetween, reducing energy loss, and making the driving force of the thrust cylinder 20 more efficiently transmitted to the slider 403. The rolling contact avoids the component wear caused by the traditional rigid abutment, prolongs the service life of the connecting rod 30 and the slider 403, and reduces the equipment maintenance frequency.

[0074] In addition, the arrangement of the roller 303 makes the relative motion between the connecting rod 30 and the slider 403 smoother, reduces the jamming phenomenon, ensures the smooth and controllable pressing-in process, improves the precision and consistency of the pressing-in of the damping rotating pin shaft 300, and is especially suitable for high-frequency batch production scenes.

[0075] Optionally, the second end of the connecting rod 30 is configured with a notch 301 to accommodate the roller 303.

[0076] The notch 301 at the second end of the connecting rod 30 provides a stable mounting space for the roller 303, ensuring that the roller 303 does not axially deviate or fall off during movement, enhancing the reliability of the structural connection. The notch 301 structure makes the installation and replacement operation of the roller 303 more convenient, reducing the maintenance difficulty and time cost. Compared with the integral structure, the notch 301 design reduces the weight of the end of the connecting rod 30, optimizes the stress distribution of the connecting rod 30, reduces the deformation caused by excessive inertia force, improves the structural strength and service life of the connecting rod 30, and ensures the stability of power transmission.

[0077] Optionally, the region where the connecting rod 30 is rotationally connected with the first vertical plate 103 / second vertical plate 104 is outwardly protruding and extended to form an extension 302 to strengthen the structural strength of the connecting rod 30.

[0078] The extension 302 at the rotationally connected region of the connecting rod 30 enhances the structural strength of the connecting rod 30, making the connecting rod 30 less likely to deform or break when transmitting thrust, improving the overall carrying capacity and durability of the mechanism, and prolonging the service life of the equipment.

[0079] The protruding and extending structure of the extension 302 also enhances the stability of the connection between the connecting rod 30 and the vertical plate, ensuring that the rotating shaft does not loosen during high-frequency motion, and ensuring the accuracy of power transmission.

[0080] Optionally, the connecting rod 30 is located between the first vertical plate 103 and the second vertical plate 104 to limit the radial displacement of the connecting rod 30.

[0081] The connecting rod 30 is located between the first vertical plate 103 and the second vertical plate 104, which forms a radial constraint on the connecting rod 30 from both sides, effectively preventing the connecting rod 30 from swinging or deviating during movement, ensuring that the connecting rod 30 always moves along the preset trajectory, improving the accuracy of power transmission. The limiting effect of the two vertical plates reduces the invalid vibration of the connecting rod 30, reduces energy loss, and makes the driving force of the thrust cylinder 20 more concentrated on the sliding block 403.

[0082] Optionally, the stand 10 is located on one side of the jacking cylinder 60, and the first horizontal plate 101 is the top plate of the stand 10. When the telescopic rod of the jacking cylinder 60 extends, the stand 10 moves upward to expand the space below the second horizontal plate 102, adapting to different sizes of radiators 400.

[0083] The layout of the stand 10 on one side of the jacking cylinder 60 optimizes the space structure of the equipment, reduces the overall floor area, and solves the problem of large floor area of traditional oil presses. The first horizontal plate 101 as the top plate is connected with the telescopic rod of the jacking cylinder 60, so that the stand 10 realizes stable up-down movement under the driving of the telescopic rod of the jacking cylinder 60. By adjusting the height of the space below the second horizontal plate 102, the mechanism can adapt to the taking, placing and pressing requirements of radiators 400 of different sizes, greatly improving the versatility of the mechanism. The flexible adjustment mode driven by the jacking cylinder 60 is more convenient for operators to quickly adjust the working space according to the specifications of the radiator 400, reduces the changeover time, and improves the production flexibility and efficiency.

[0084] Optionally, the thrust cylinder 20 is located below the first horizontal plate 101 and is suspended by the lifting arm 70. One end of the lifting arm 70 is detachably connected with the first horizontal plate 101, and the other end is rotatably connected with the cylinder body of the thrust cylinder 20, so as to adjust the relative angle of the thrust cylinder 20 according to the extension and retraction movement of the telescopic rod.

[0085] The design of the thrust cylinder 20 suspended below the first horizontal plate 101 by the lifting arm 70 and the rotatable adjustment of the angle make it possible to freely adjust the relative angle according to the extension and retraction movement of the telescopic rod, ensuring that the connecting rod 30 is always in the best stress state and avoiding power transmission loss caused by fixed angle.

[0086] The detachable connection of the lifting arm 70 and the first horizontal plate 101 facilitates the installation, maintenance and replacement of the thrust cylinder 20. The suspension structure reduces the rigid connection between the thrust cylinder 20 and the stand 10, reduces vibration transmission, makes the pressing action more stable, improves the pressing precision of the damping rotary pin shaft 300, and at the same time facilitates the adjustment of the installation position of the thrust cylinder 20 according to the requirements of different radiators 400, enhancing the adaptability of the mechanism.

[0087] Optionally, the lifting arm 70 is provided on both sides of the thrust cylinder 20.

[0088] The structure of the hoisting arm 70 on both sides of the thrust cylinder 20 makes the force on the cylinder more balanced, avoids tilting or deformation caused by single-sided suspension, ensures that the thrust cylinder 20 always remains in a horizontal stable state, and improves the stability of power output. The bilateral support enhances the rigidity of the hoisting structure, can better resist the reaction force in the pressing process, and prevents the hoisting arm 70 from loosening or breaking. In addition, it can also reduce the deviation in the power transmission process, improve the consistency and reliability of the damping rotary pin shaft 300 pressing, and reduce the quality fluctuation in batch production.

[0089] Optionally, it also includes a rack 80 provided with a fixed plate 801 on the top for mounting the jacking cylinder 60; wherein the fixed plate 801 is configured with a groove 802 on one side to accommodate the stand 10, so as to define the assembly position of the stand 10 and the jacking cylinder 60.

[0090] The fixed plate 801 on the top of the rack 80 provides a stable mounting base for the jacking cylinder 60, ensuring that the cylinder will not loosen in high-frequency motion, and improving the overall stability of the mechanism.

[0091] The groove 802 on one side of the fixed plate 801 precisely positions the accommodation of the stand 10, ensuring the accurate relative position of the stand 10 and the jacking cylinder 60, and avoiding motion interference or power transmission loss caused by assembly deviation. The limiting action of the groove 802 simplifies the assembly process of the equipment and reduces the installation difficulty.

[0092] Optionally, it also includes a positioning tray 90 provided on the rack 80 for mounting the heat sink 400.

[0093] The positioning tray 90 on the rack 80 provides a stable placement platform for the heat sink 400, ensuring that the heat sink 400 will not shake or shift during the pressing process, and solving the problem of pressing deviation caused by unstable placement of the heat sink 400 in traditional operation. The positioning tray 90 makes the taking and placing operation of the heat sink 400 more convenient, and the operator does not need to repeatedly calibrate the position of the heat sink 400, reducing the operation difficulty.

[0094] The tray structure can be adaptively designed according to the shape of the heat sink 400, enhancing the compatibility of different models of heat sinks 400, quickly adapting to new heat sinks 400 by replacing the tray, reducing the equipment modification cost, improving the production flexibility, and protecting the bottom surface of the heat sink 400 from being damaged.

[0095] Optionally, it also includes a positioning support structure 100 provided on the positioning tray 90 and / or the rack 80 to support the heat sink 400 and limit its position.

[0096] The positioning support structure 100 forms multi-directional limiting constraints on the heat sink 400 by setting support points on the positioning tray 90 and / or the rack 80, ensures that the heat sink 400 is fixed in position during pressing, and avoids problems of pressing accuracy caused by displacement due to force.

[0097] The positioning support structure 100 makes the positioning of the heat sink 400 more accurate, ensures that the pressing position of the damping rotating pin shaft 300 is consistent with the design requirements of the heat sink 400, and improves assembly quality. Compared with the traditional way without a positioning structure, this design reduces the positioning time of the operator, improves the assembly efficiency of a single heat sink 400, and facilitates adjustment of the support point position according to the structure of different heat sinks 400, thereby enhancing the universality and adaptability of the mechanism.

[0098] Optionally, the positioning support structure 100 includes a first fixing member 1001 arranged on the positioning tray 90 or the rack 80 to support and fix the heat sink, and a second fixing member 1002 detachably connected with the first fixing member 1001 to abut and fix the heat sink 400. The surfaces of the first fixing member 1001 and the second fixing member 1002 in contact with each other are provided with tooth structures to further prevent relative displacement of the second fixing member 1002 and the first fixing member 1001.

[0099] The tooth structures on the contact surfaces of the first fixing member 1001 and the second fixing member 1002 increase the friction force by mutual engagement, effectively preventing relative displacement of the two members due to force during pressing, and ensuring the positioning stability of the positioning support structure 100. The engagement of the tooth structures makes the adjustment of the support position more accurate, and the operator can adjust the engagement position of the teeth to fine-tune the support height or horizontal distance, thereby improving the positioning accuracy.

[0100] Optionally, the first fixing member 1001 is L-shaped, one arm of the first fixing member 1001 is detachably connected with the rack 80 or the positioning tray 90, and the other arm is detachably connected with the second fixing member 1002. The L-shaped structure realizes convenient connection of the fixing member with the rack 80 / tray and the second fixing member 1002, simplifies the structure design while ensuring the support strength, and facilitates installation and adjustment.

[0101] The L-shaped first fixing member 1001 has one arm connected with the rack 80 or the positioning tray 90 and the other arm connected with the second fixing member 1002, forming a stable right-angle support structure and enhancing the rigidity and stability of the positioning support. The spatial layout of the L-shaped structure optimizes the distribution of the support points, can effectively support the heat sink 400 in a limited space, and is particularly suitable for heat sinks 400 with compact structures. The detachable connection mode makes the installation and adjustment of the fixing member more convenient, and the operator can flexibly adjust the position of the fixing member according to the size of the heat sink 400, thereby improving the adaptability of the mechanism.

[0102] Optionally, the second fixing member 1002 is L-shaped, one arm of the second fixing member 1002 is detachably connected with the rack 80 or the positioning tray 90, and the other arm is in abutment with the heat sink 400.

[0103] The L-shaped structure is adapted to the edge profile of the heat sink 400, and stable positioning of the heat sink 400 is achieved through multi-directional abutment.

[0104] The arm of the L-shaped second fixing member 1002 in direct contact with the heat sink 400 can be adaptively designed according to the shape of the heat sink 400 to ensure close contact and avoid damage to the surface of the heat sink 400. The detachable nature of the L-shaped structure enables the second fixing member 1002 to be quickly replaced to adapt to heat sinks 400 of different shapes, enhancing the versatility of the mechanism.

[0105] Optionally, it also includes: an air source processor 200 arranged in the rack 80 and connected with the lifting cylinder 60 / thrust cylinder 20 to provide air source for the cylinder.

[0106] The air source processor 200 is connected with the lifting cylinder 60 and the thrust cylinder 20, which can filter, regulate pressure and lubricate the input air source, ensuring that the cylinder obtains stable and clean working air source, avoiding cylinder failure caused by air source impurities or pressure fluctuations, and prolonging the service life of the cylinder. The pressure regulating function of the air source processor 200 enables the operator to accurately adjust the cylinder output force according to the pressing-in requirements of the damping rotary pin shaft 300, adapt to the assembly requirements of rotary pin shafts of different specifications, and improve the operation flexibility.

[0107] Exemplarily, the operation flow of the pressing-in mechanism for assembling the damping rotary pin shaft 300 to the related part of the heat sink 400 shell is as follows:

[0108] Prepare the heat sink 400 to be assembled, the damping rotary pin shaft 300 and the corresponding positioning tray 90. According to the model of the heat sink 400, select the appropriate positioning support structure 100, detachably connect one arm of the L-shaped first fixing member 1001 with the positioning tray 90 through bolts, and connect the other arm with the second fixing member 1002 which is also L-shaped through toothed structure engagement, adjust the engagement position of the teeth to realize fine adjustment of the support height and horizontal distance, so that the second fixing member 1002 is adapted to the edge profile of the heat sink 400, and ensure that the heat sink 400 can be stably supported and positioned accurately after being placed.

[0109] The heat sink 400 is placed in the positioning tray 90 on the rack 80, so that the housing part of the heat sink 400 to be installed with the damping rotary pin shaft 300 is directed towards the slider 403 of the pressing device and the direction of the stop block 50. Under the action of the gravity of the heat sink 400 itself and the positioning support structure 100, the bottom of the heat sink 400 is in close contact with the positioning tray 90, and the side is in abutting contact with the arm body of the second fixing piece 1002. At this time, the limiting part 503 at the bottom of the stop block 50 is located above the housing of the heat sink 400 and is close to, forming a secondary positioning constraint on the heat sink 400 from above, ensuring that the insertion position of the damping rotary pin shaft 300 is accurately corresponding to the position of the avoidance groove 502 of the stop part 501 of the stop block 50, without the need for repeated calibration by the operator, reducing the operation difficulty.

[0110] If the size of the heat sink 400 is large or the space for taking and placing is insufficient, the jacking cylinder 60 can be started, the telescopic rod of the jacking cylinder 60 is extended, drives the stand 10 to move upward along the axial direction, expands the space below the second transverse plate 102, and facilitates the operator to smoothly place the heat sink 400 in place. After the heat sink 400 is placed, the telescopic rod of the jacking cylinder 60 is retracted, so that the stand 10 is lowered to a suitable pressing height.

[0111] The operator places the damping rotary pin shaft 300 in the clamp formed by the slider 403 and the stop block 50, ensures that the axis of the damping rotary pin shaft 300 is basically consistent with the axis of the avoidance groove 502 of the stop part 501 of the stop block 50. At this time, one end of the damping rotary pin shaft 300 is close to the pressing part 4031 of the slider 403, the other end is aligned with the avoidance groove 502, and is in the limited space between the slider 403 and the stop block 50, so as to avoid horizontal deviation in the subsequent pressing process.

[0112] The thrust cylinder 20 is started, the telescopic rod of the thrust cylinder 20 is extended, since the thrust cylinder 20 is suspended below the first transverse plate 101 through the hoisting arm 70, and the other end of the hoisting arm 70 is rotationally connected with the cylinder body of the thrust cylinder 20, the thrust cylinder 20 can automatically adjust the relative angle according to the telescopic movement of the telescopic rod, so as to ensure that the connecting rod 30 is always in the best stress state. The extension of the telescopic rod of the thrust cylinder 20 drives the first end of the connecting rod 30 rotationally connected therewith to move, the connecting rod 30 rotates around the rotationally connected points of the first vertical plate 103 and the second vertical plate 104 of the stand 10 as a fulcrum, the second end of the connecting rod 30 passes through the through hole 1021 of the second transverse plate 102 of the stand 10, and the roller 303 at the end thereof abuts against the slider 403 of the pressing device and pushes the slider 403 to move.

[0113] The slider 403 smoothly slides in the sliding groove of the symmetrically arranged first sliding rail 401 and second sliding rail 402, the pressing part 4031 of the slider 403 protrudes from the accommodating cavity limited by the sliding rail, accurately inserts into the top space of the heat sink 400, and exerts axial pressure on the damping rotary pin shaft 300. During the movement of the slider 403 to the direction of the stop block 50, the shell of the damping rotary pin shaft 300 to be installed in the heat sink 400 abuts against the stop block 50, the stop block 50 provides rigid support for the pressing action, and ensures that the pressure exerted by the slider 403 is efficiently converted into the insertion and assembly power of the damping rotary pin shaft 300.

[0114] With the continuous movement of the slider 403, the damping rotary pin shaft 300 is gradually inserted into the shell of the heat sink 400 under the action of pressure, until the end of the damping rotary pin shaft 300 protrudes from the shell of the heat sink 400 by a certain length as required by the design, and the pressing assembly is completed. At this time, the extension rod of the push cylinder 20 is retracted, the connecting rod 30 is reversely rotated, and the slider 403 is retracted to the initial position under the action of its own gravity or the reset device.

[0115] The lifting cylinder 60 is started to lift the stand 10, and the operator takes out the heat sink 400 with the assembled damping rotary pin shaft 300 from the positioning tray 90, and completes one assembly cycle. If the assembly of the next heat sink 400 is needed, the above steps of positioning and placing the heat sink 400, feeding the damping rotary pin shaft 300, and executing the pressing action can be repeated. Through the operation process of the embodiment, the precise and efficient assembly of the damping rotary pin shaft 300 on the heat sink 400 can be realized, and the consistency of the assembly quality of each product in batch production can be effectively ensured.
