Description

Technical Field

[0001] This application relates to the field of heat dissipation component assembly technology, and in particular to a product assembly fixture. Background Technology

[0002] To ensure operational stability, electronic and communication equipment is usually equipped with a heat sink system for heat dissipation. A complex heat sink system is mainly composed of multiple heat dissipation components.

[0003] Reference Figure 1 In related technologies, the heat dissipation component includes a heat dissipation workpiece 16, screws 17, springs 18, washers 19, and C-shaped clips 20. The heat dissipation workpiece 16 is rectangular, and its top and / or bottom walls are typically welded with other structures as needed. Through holes 21 are provided at the four corners of the heat dissipation workpiece 16, with each screw 17 corresponding to one of the through holes 21. The springs 18, washers 19, and the through holes 21 of the heat dissipation workpiece 16 are sequentially fitted onto the corresponding screws 17. The washers 19 include a cylindrical portion and an insulating portion. The cylindrical portion extends into the through hole 21 of the heat dissipation workpiece 16, and the insulating portion is located within the spring. Between the surface of the screw 17 and the heat dissipation workpiece 16, there is a groove 22 between the screw 17 and the threaded end, and a C-type clip 20 is installed in the groove 22. Specifically, the side of the heat dissipation workpiece 16 away from the head of the screw 17 has an annular groove along the circumference of each through hole 21. The outer diameter of the C-type clip 20 after installation is larger than the inner diameter of the washer 19 and smaller than the inner diameter of the annular groove. After the heat dissipation components are assembled, the spring 18 is in a compressed state. Under the elastic force of the spring 18, the C-type clip 20 abuts against the surface of the cylindrical part of the washer 19. The threaded end of the screw 17 is used to connect with other heat dissipation components. When assembling the heat dissipation components, the spring 18, washer 19 and rectangular heat dissipation workpiece 16 are first placed on the screw 17 in sequence, and then the C-type clip 20 is clamped in the groove 22 of the screw 17 to limit the heat dissipation workpiece 16.

[0004] Regarding the aforementioned technologies, after the spring 18, washer 19, and heat dissipation component 16 are sequentially fitted onto the screw 17, the washer 19 and heat dissipation component 16 will block the groove 22 position under the elastic support of the corresponding spring 18. When installing the C-type clip 20, the method of manually pressing the heat dissipation component 16 to compress the spring 18 and expose the groove 22 on the screw 17 is time-consuming and labor-intensive, and the heat dissipation component 16 is prone to deformation.

Two fixed pressure-bearing plates are provided, and the two fixed pressure-bearing plates are respectively used to abut against the two rows of gaskets along the length direction of the heat dissipation component and the heat dissipation workpiece. The sliding pressure-bearing plate and... The fixed pressure plates are one-to-one correspondents, and the sliding pressure plates are slidably disposed on the first pressure body. The sliding pressure plates are located on the same side as the corresponding fixed pressure plates. The sliding pressure plates are used to abut against the gaskets of the two screws in the length direction of the heat dissipation component and the heat dissipation workpiece. The second pressure body has a sliding cavity. The ends of the fixed pressure plates and the sliding pressure plates away from the first pressure body are used to slide into or out of the sliding cavity of the second pressure body. The adjusting locking component is used to adjust the sliding pressure plates to move toward or away from the corresponding fixed pressure plates and to lock the position of the sliding pressure plates.

[0013] Preferably, the adjusting locking assembly includes a mounting base, a sliding locking pin, and an elastic element. The second mounting base corresponds to the sliding pressure plate and is disposed on the second pressure body. The sliding locking pin is slidably disposed on the mounting base, and the sliding direction of the sliding locking pin is parallel to the length direction of the sliding pressure plate. The end of the sliding locking pin is designed as a convex arc surface, which is used to slide against the end of the sliding pressure plate. The end of the sliding pressure plate is designed with a snap-fit ​​groove, which is used to snap into the corresponding sliding locking pin. The elastic element is used to drive the sliding locking pin to move toward the sliding pressure plate, and the elastic force of the elastic element is greater than the sliding friction of the sliding pressure plate.

[0014] Preferably, the elastic element includes a push spring for driving the sliding locking pin to move toward the sliding bearing plate, one end of the push spring being disposed on the mounting base and the other end being disposed on the corresponding sliding locking pin.

[0015] Preferably, the first pressure-bearing body is L-shaped and the second pressure-bearing body is U-shaped. One end of the second pressure-bearing body is used to extend into the first pressure-bearing body, and the other end is used to engage with the first pressure-bearing body. Each sliding pressure-bearing piece has a mounting seat at both ends, and the mounting seats at both ends of the sliding pressure-bearing piece are arranged opposite each other on both sides of the second pressure-bearing body.

[0016] Preferably, the length of the sliding pressure plate near the opening of the first pressure body is less than the length of the sliding pressure plate away from the opening of the first pressure body, and the lengths of the two sliding locking pins near the opening of the second pressure body are less than the lengths of the two sliding locking pins away from the opening of the second pressure body.

[0017] Preferably, the sliding pressure plate includes a pressure-bearing part and a sliding part. The pressure-bearing part is used to abut between the gasket and the heat dissipation workpiece. The sliding part is disposed opposite to each other at both ends of the pressure-bearing part.

[0019] Preferably, the pressing body is provided with an adjusting rod, and the output end of the quick clamp is provided with a strip-shaped hole that slides with the adjusting rod. Two washers and two nuts are sleeved on the adjusting rod, with the two washers located between the two nuts. The nuts are used to press the corresponding washers onto the output end of the corresponding quick clamp.

[0020] In summary, this application includes the following beneficial technical effects:

[0021] During the assembly of the heat dissipation component, the heads of the four screws are sequentially placed into their corresponding limiting bodies. These limiting bodies keep the screws upright and prevent lateral movement. Next, a spring and a washer are sequentially placed on each screw. Then, a heat dissipation component is placed on all four screws. Under gravity, the heat dissipation component rests on the cylindrical parts of the four washers. Supported by the springs, the washers and heat dissipation component cover the grooves on the screws. A force-equalizing mechanism then abuts against the heat dissipation component. A pressure-applying mechanism applies a force towards the screw heads to the force-equalizing mechanism, causing it to move the washers and heat dissipation component downwards until the grooves on the screws are exposed. The pressure-applying mechanism maintains its contact with the force-equalizing mechanism. The process involves pressing the C-shaped clips into the screw grooves and clamping them in place with pliers until all four C-shaped clips are installed. Then, the pressure on the force-equalizing mechanism is released by the pressure application mechanism. The spring force lifts the gasket, heat sink, and force-equalizing mechanism, allowing the C-shaped clips to move into the annular groove of the heat sink and limit its position, preventing the spring, gasket, and heat sink from detaching from the screw. The force-equalizing mechanism is then removed, allowing the installed heat sink component to be taken out from the four limiting bodies, completing the assembly of the heat sink component. This process eliminates the need for continuous manual pressing of the heat sink component, making it simple, quick, time-saving, and labor-saving. Furthermore, the force-equalizing mechanism prevents the heat sink component from deforming. Attached Figure Description

[0031] The following combination Figures 1-8 This application will be described in further detail.

[0032] Example 1:

[0033] This application discloses a product assembly fixture. (Refer to...) Figure 1 and Figure 2 The product assembly fixture includes a tooling base 1, a force-equalizing mechanism, and a pressure-applying mechanism 3. The tooling base 1 has a rectangular cross-section and is equipped with limiting bodies that correspond one-to-one with the screws 17 of the heat dissipation component. The limiting bodies are used to fix the heads of the corresponding screws 17. Specifically, each limiting body includes limiting holes 2 formed on the surface of the tooling base 1. Four limiting holes 2 are rectangularly distributed and aligned with the four screws 17 of the heat dissipation component. When the four screws 17 are inserted into the corresponding limiting holes 2, and the heat dissipation workpiece 16 is fitted onto the four screws 17, the length direction of the heat dissipation workpiece 16 is parallel to the length direction of the tooling base 1. The cross-section of the limiting hole 2 is adapted to the cross-section of the screw head 17 to place the screw head into the corresponding limiting hole 2, maintaining the vertical placement of the screw 17. In other embodiments, the limiting hole 2 can also be replaced with a limiting cylinder, a limiting ring, or other structures, which can also limit the screws 17.

[0034] Reference Figure 2 The force equalization mechanism is used to abut against the radiator component to distribute pressure, and the pressure application mechanism 3 is provided on the tooling base 1 to apply a force to the force equalization mechanism in the direction of approaching the head of the screw 17.

[0035] When assembling the heat dissipation component, the heads of the four screws 17 are sequentially placed into the corresponding limiting holes 2, keeping the screws 17 upright and preventing lateral movement. Next, a spring 18 and a washer 19 are sequentially fitted onto each screw 17. Then, a heat dissipation component 16 is fitted onto all four screws 17. Under gravity, the heat dissipation component 16 rests on the cylindrical portions of the four washers 19. At this point, supported by the spring 18, the washers 19 and the heat dissipation component 16 cover the grooves 22 on the screws 17. Then, a force-equalizing mechanism abuts against the heat dissipation component, for example, against the surface of the heat dissipation component 16 or against the washers 19. Finally, a pressure-applying mechanism 3 applies a force towards the head of the screw 17, causing the force-equalizing mechanism to move the washers 19 and the heat dissipation component 16 downwards, compressing the spring 18 until the screws are exposed. Remove the screw 17 from the groove 22, maintain the pressure of the pressure applying mechanism 3 on the force equalizing mechanism, then sequentially place the C-type clips 20 into the groove 22 of the screw 17 and use clamps to hold the C-type clips 20 in the groove 22. After all four C-type clips 20 are installed, release the pressure of the force equalizing mechanism through the pressure applying mechanism 3. Under the elastic force of the spring 18, the washer 19, the heat dissipation workpiece 16 and the force equalizing mechanism are lifted, so that the C-type clips 20 move into the annular groove of the heat dissipation workpiece 16 and limit the heat dissipation workpiece 16, so that the spring 18, the washer 19 and the heat dissipation workpiece 16 will not fall off the screw 17. Then remove the force equalizing mechanism, and the installed heat dissipation component can be taken out from the four limiting holes 2, completing the assembly of the heat dissipation component. There is no need to manually press the heat dissipation workpiece 16 continuously, which is simple, quick and saves time and effort. At the same time, the heat dissipation workpiece 16 is not easily deformed.

[0036] Reference Figure 2 and Figure 3 To facilitate pressure distribution, the force-equalizing mechanism includes a cover plate 4, which is attached to the side of the heat dissipation workpiece 16 away from the head of the screw 17. The pressure-applying mechanism 3 is used to press the heat dissipation workpiece 16 against the cover plate 4. Specifically, in this embodiment, other heat dissipation structures are welded to the center of the heat dissipation workpiece 16. Therefore, in this embodiment, the cover plate 4 is annular, and its center avoids the heat dissipation structure at the center of the heat dissipation workpiece 16. In other embodiments, the shape of the cover plate 4 can be set according to actual needs. By setting the cover plate 4, the contact area with the heat dissipation workpiece 16 is increased, thereby effectively dispersing pressure and effectively avoiding deformation of the copper material and the brazed heat dissipation workpiece 16.

[0037] Reference Figure 2To facilitate applying pressure to the cover plate 4, the pressure applying mechanism 3 includes a quick clamp 31 and a pressing body 32 mounted on the quick clamp 31. The quick clamp 31 is fixed to the tooling base 1 by bolts. Two quick clamps 31 are arranged opposite each other, and multiple limiting bodies are located between the two quick clamps 31. Furthermore, the arrangement direction of the two quick clamps 31 is parallel to the length direction of the tooling base 1. Specifically, the quick clamp 31 includes a clamp base 311, an output end 312, an operating end 313, and a transmission body 314. The clamp base 311 is fixed to the tooling base 1 by bolts. The output end 312 is hinged to the clamp base 311. The transmission body 314 is hinged to the side of the clamp base 311 away from the output end 312. The operating end 313 is hinged to both the output end 312 and the transmission body 314. The hinge axes of the output end 312, the transmission body 314, and the operating end 313 are all parallel to the tooling base 1. In the width direction of the mounting base 1, when the operating end 313 is lifted upwards, the transmission body 314 gradually rotates to a vertical state, pulling the output end 312 upwards; when the operating end 313 is pressed down, the transmission body 314 gradually rotates to a horizontal state, causing the output end 312 to move downwards. Thus, lifting the operating end 313 causes the output end 312 to move upwards, and pressing down the operating end 313 causes the output end 312 to move downwards. Furthermore, based on the structural principle of the quick clamp 31, the position of the output end 312 can be locked. Further, the quick clamp 31 is a standard part in the clamping field, also known as a quick clamp, quick fixture, etc. Its specific operating principle will not be elaborated here.

[0038] Reference Figure 2 The pressing body 32 is set on the output end 312 of the quick clamp 31. The pressing body 32 can be cylindrical, spherical or cup-shaped. The pressing body 32 is made of rubber and has a certain cushioning effect. The pressing body 32 is used to abut against the cover plate 4 to drive the heat dissipation workpiece 16 to move toward the head of the screw 17.

[0039] Reference Figure 2 Each pressing body 32 has an adjusting rod 13 fixed to its upper end. The output end 312 of the quick clamp 31 has a slotted hole that slides with the adjusting rod 13. Two washers 14 are fitted on the adjusting rod 13 and two nuts 15 are threadedly connected to it. The two washers 14 are located between the two nuts 15, and the nuts 15 are used to press the corresponding washers 14 onto the output end 312 of the corresponding quick clamp 31. The vertical and horizontal positions of the pressing body 32 can be adjusted by the cooperation of the adjusting rod 13, washers 14 and nuts 15, thereby adjusting the clamping force and making it suitable for heat dissipation workpieces 16 of different lengths and thicknesses.

[0040] Reference Figure 2 and Figure 3The surface of the tooling base 1 is provided with multiple clearance grooves 23. When heat pipes and other components are welded to the bottom wall of the heat dissipation workpiece 16, the clearance grooves 23 can effectively avoid the structure welded to the bottom wall of the heat dissipation workpiece 16, so that the structure of the bottom wall of the heat dissipation workpiece 16 will not interfere with the tooling base 1 during the downward movement of the heat dissipation workpiece 16.

[0041] The implementation principle of Embodiment 1 of this application is as follows: When assembling the heat dissipation component, the output end 312 of the quick clamp 31 is in a tilted state, providing sufficient space for the placement of the heat dissipation workpiece 16. Then, the heads of the four screws 17 are sequentially placed into the corresponding limiting holes 2, keeping the screws 17 upright and preventing lateral movement. Next, a spring 18 and a washer 19 are sequentially fitted onto each screw 17. Then, the heat dissipation workpiece 16 is fitted onto the four screws 17 together. Under the action of gravity, the heat dissipation workpiece 16 is fitted onto the cylindrical parts of the four washers 19. With the support of the spring 18, the washers 19 and the heat dissipation workpiece 16 cover the groove 22 on the screw 17. Finally, the cover plate 4 is fitted onto the surface of the heat dissipation workpiece. The cover plate 4 is positioned so that its center is aligned with the surface of the heat dissipation workpiece 16. Then, the operating ends 313 of the quick clamps 31 at both ends are pressed simultaneously, causing the output ends 312 of the quick clamps 31 on both sides to rotate the pressing body 32 downwards. Then, the pressing body 32 abuts against the surface of the cover plate 4. As the pressing body 32 continues to press down, it drives the cover plate 4, the heat dissipation workpiece 16 and the gasket 19 to move down until the groove 22 on the screw 17 is exposed. At this time, the operating ends 313 of the two quick clamps 31 are released, and the position of the heat dissipation workpiece 16 is fixed under the action of the quick clamps 31. Then, the C-type clips 20 are put on the groove 22 of the screw 17 in sequence and the C-type clips 20 are clamped in the groove 22 with pliers to complete the installation of the four C-type clips 20.

[0042] Then, the operator simultaneously lifts the operating ends 313 of the two quick clamps 31, causing the output ends 312 of the two quick clamps 31 to tilt upwards, releasing the pressure on the cover plate 4. Then, under the elastic force of the spring 18, the pad 19, the heat dissipation workpiece 16 and the cover plate 4 are lifted, so that the C-type clip 20 moves into the annular groove of the heat dissipation workpiece 16 and limits the heat dissipation workpiece 16. Then, the cover plate 4 on the surface of the heat dissipation workpiece 16 is removed, and the installed heat dissipation component can be taken out from the four limiting holes 2, completing the assembly of the heat dissipation component. This achieves the goal of eliminating the need for manual continuous pressing of the workpiece during the assembly process, which is simple, quick, time-saving and labor-saving, and the heat dissipation workpiece 16 is not easily deformed.

[0043] Example 2:

[0044] Reference Figure 4 and Figure 5This embodiment differs from Embodiment 1 in that it is applicable to situations where the heat dissipation workpiece 16 is easily deformable and / or has a complex surface structure but no bottom wall structure. Specifically, the force equalization mechanism includes a first pressure-bearing body 5, a second pressure-bearing body 6, a fixed pressure-bearing plate 7, a sliding pressure-bearing plate 8, and an adjustment and locking assembly. The first pressure-bearing body 5 and the second pressure-bearing body 6 are arranged opposite each other and are respectively used to abut against the pressing body 32 of the pressure application mechanism 3. Specifically, to improve the overall strength of the force equalization mechanism, the first pressure-bearing body 5 is L-shaped, and the width of one end of the first pressure-bearing body 5 is much larger than the width of the other end. The first pressure-bearing body 5 has its wide end abutting against the pressing body 32. The second pressure-bearing body 6 is U-shaped, with one end wider than the other. The narrow end of the second pressure-bearing body 6 extends into the first pressure-bearing body 5, and the wide end engages with the first pressure-bearing body 5. At the same time, the wide end of the second pressure-bearing body 6 abuts against the pressing body 32, thus forming a rectangular frame by splicing the first pressure-bearing body 5 and the second pressure-bearing body 6 together. By abutting the wide ends of the first pressure-bearing body 5 and the second pressure-bearing body 6 against the corresponding pressing body 32, the pressure application area can be guaranteed, and stress concentration can be avoided.

[0045] Reference Figure 4 and Figure 5 To improve the structural stability of the first pressure-bearing body 5 and the second pressure-bearing body 6, a spring jumper 30 is installed at the wide end of the second pressure-bearing body 6. The spring jumper 30 is composed of a spring and a snap-fit ​​block. The narrow end of the first pressure-bearing body 5 is provided with a snap-fit ​​groove that engages with the spring jumper 30. Specifically, the snap-fit ​​method of the spring jumper 30 is existing technology and will not be described in detail here.

[0046] Reference Figure 4 and Figure 5 A fixing pressure plate 7 is disposed on the first pressure-bearing body 5. The length direction of the fixing pressure plate 7 is parallel to the length direction of the heat dissipation workpiece 16 during assembly. Further, the length direction of the fixing pressure plate 7 is parallel to the length direction of the narrow end of the first pressure-bearing body 5. Two fixing pressure plates 7 are provided. The spacing between the two fixing pressure plates 7 facing the same direction is adapted to the spacing of the two screws 17 corresponding to the width direction of the heat dissipation component, so that the two fixing pressure plates 7 can respectively correspond to the two rows of screws 17 of the heat dissipation component. The fixing pressure plate 7 is used to abut against the two gaskets 19 and the heat dissipation workpiece 16 in the length direction of the heat dissipation component. Specifically, the fixing pressure plate 7 is fixed to the first pressure-bearing body 5 by bolts to facilitate adjustment of the distance between the two fixing pressure plates 7, which can be used for heat dissipation components with different screw 17 spacings.

[0047] Reference Figure 5 and Figure 6The sliding pressure plate 8 corresponds one-to-one with the fixed pressure plate 7. The sliding pressure plate 8 slides through the first pressure body 5 and is located on the same side as the corresponding fixed pressure plate 7. Specifically, the sliding pressure plate 8 is located on the side of the corresponding fixed pressure plate 7 away from the narrow end of the first pressure body 5. The sliding pressure plate 8 is used to abut between the washer 19 of the two screws 17 and the heat dissipation workpiece 16 in the length direction of the heat dissipation component. The sliding direction of the sliding pressure plate 8 is perpendicular to the length direction of the fixed pressure plate 7 and parallel to the length direction of the fixed pressure plate 7. To improve the sliding effect of the two sliding pressure plates 8, a guide rail 25 is provided in the first pressure body 5. The sliding pressure plate 8 slides with the guide rail 25. The lengths of both the fixed pressure plate 7 and the sliding pressure plate 8 are greater than the length of the heat dissipation workpiece 16.

[0048] Reference Figure 5 and Figure 6 The second pressure-bearing body 6 has a sliding cavity 24 at one wide end. The fixed pressure-bearing plate 7 and the sliding pressure-bearing plate 8 are used to slide into or out of the sliding cavity 24 of the second pressure-bearing body 6 at the ends away from the first pressure-bearing body 5. The adjusting locking member is used to adjust the sliding pressure-bearing plate 8 to move toward or away from the corresponding fixed pressure-bearing plate 7 and to lock the position of the sliding pressure-bearing plate 8.

[0049] When the four screws 17 are inserted into the corresponding limiting holes 2, and the springs 18 and washers 19 are both fitted onto the screws 17, the wider end of the first pressure body 5 is positioned below the pressing body 32 on one side, so that the length direction of the fixed pressure plate 7 is parallel to the length direction of the tooling base 1. Then, the first pressure body 5 is moved so that the two rows of screws 17 are respectively positioned between the two sets of fixed pressure plates 7 and sliding pressure plates 8, and the two fixed pressure plates 7 are positioned above the isolation part of the screw 17 washer 19 and abut against the upper surface of the isolation part of the washer 19. Then, the second pressure body 6 is aligned with the first pressure body 5, and the narrow end of the second pressure body 6 is gradually slid into the first pressure body 5. During this process, the ends of the two fixed pressure plates 7 and the two sliding pressure plates 8 that are away from the first pressure body 5 slide into the first pressure body 5. In the sliding cavity 24 of the second pressure body 6, the sliding pressure plate 8 is adjusted to move towards the corresponding fixed pressure plate 7 by adjusting the locking member, so that the sliding pressure plate 8 also abuts against the upper surface of the isolation part of the corresponding gasket 19. Then, the second pressure body 6 and the first pressure body 5 are spliced ​​into place and locked by the spring jumper 30. The position of the sliding pressure plate 8 is locked by adjusting the locking member. Then, the heat dissipation workpiece 16 is put on the four screws 17. The quick clamp 31 makes the two pressing bodies 32 press down on the first pressure body 5 and the second pressure body 6 respectively. The fixed pressure plate 7 and the sliding pressure plate 8 abut against the gasket 19 to compress the spring 18. The heat dissipation workpiece 16 automatically moves down under the action of gravity until the groove 22 on the screw 17 is exposed, and the C-type clip 20 can be installed.

[0050] After the C-type clip 20 is installed, the pressing body 32 releases the first pressure body 5 and the second pressure body 6. Under the elastic force of the spring 18, the gasket 19 and the heat dissipation workpiece 16 are driven upward until they abut against the C-type clip 20. Then, the second pressure body 6 is slid away from the first pressure body 5. The sliding pressure plate 8 is adjusted away from the corresponding fixed pressure plate 7 by adjusting the locking member, so that the upper and lower surfaces of the sliding pressure plate 8 are separated from the gasket 19 and the heat dissipation workpiece 16 until the second pressure body 6 is completely separated from the first pressure body 5. Then, the first pressure body 5 is moved horizontally so that the two fixed pressure plates are separated. The upper and lower surfaces of the fixed pressure plate 7 are separated from the gasket 19 and the heat dissipation workpiece 16. At this time, the distance between the fixed pressure plate 7 and the corresponding sliding pressure plate 8 is completely greater than the diameter of the screw 17. The screw 17 of the assembled heat dissipation component can then be removed from between the fixed pressure plate 7 and the sliding pressure plate 8. In this embodiment, for heat dissipation workpiece 16 with a relatively soft material, pressure can be effectively avoided. In the case where the upper surface of the heat dissipation workpiece 16 has a complex structure, this embodiment can also effectively avoid contact with the complex structure on the heat dissipation workpiece 16, thus avoiding deformation of the heat dissipation workpiece 16.

[0051] Reference Figure 6 , Figure 7 and Figure 8 To facilitate the adjustment and locking of the sliding pressure plate 8 in the direction of moving closer to or further away from the corresponding fixed pressure plate 7, the adjustment and locking assembly includes a mounting base 9, a sliding locking pin 10, and an elastic element. The mounting base 9 corresponds to the sliding pressure plate 8; specifically, one mounting base 9 corresponds to each end of the sliding pressure plate 8, meaning there are four mounting bases 9. The mounting bases 9 are located on the second pressure body 6. Specifically, two mounting bases 9 at each end of the sliding pressure plate 8 are located at opposite ends of the second pressure body 6. A fixing pin 2 is fixed to each mounting base 9. 6. The sliding locking pin 10 is slidably sleeved on the fixing pin 26 of the mounting base 9. The sliding direction of the sliding locking pin 10 is parallel to the length direction of the sliding bearing plate 8. The end of the sliding locking pin 10 is designed as an outward convex arc surface, which is used to slide against the end of the sliding bearing plate 8. The end of the sliding bearing plate 8 is designed with a snap-fit ​​groove 11, which is used to snap-fit ​​with the corresponding sliding locking pin 10. The elastic element is used to drive the sliding locking pin 10 to move towards the sliding bearing plate 8. The elastic force of the elastic element is greater than the sliding friction force of the sliding bearing plate 8.

[0052] Reference Figure 6 , Figure 7 and Figure 8 To facilitate the movement of the sliding locking pin 10 toward the sliding bearing plate 8, the elastic element includes a push spring 12, which is sleeved on the corresponding fixing pin 26. One end of the push spring 12 is fixed to the mounting base 9, and the other end is fixed to the corresponding sliding locking pin 10. The elastic force of the push spring 12 is greater than the frictional force of the sliding bearing plate 8.

[0053] As the second pressure-bearing body 6 gradually extends into the first pressure-bearing body 5, the convex arc surfaces of the sliding locking pins 10 at both ends of the second pressure-bearing body 6 first abut against the sliding pressure plate 8 and move towards the corresponding fixed pressure plate 7 until the sliding pressure plate 8 abuts against the washer 19. At this time, the screw 17 and the washer 19 limit the position of the sliding pressure plate 8. As the second pressure-bearing body 6 continues to slide, the sliding locking pins 10 move towards the corresponding mounting base 9, compressing the push spring 12 until the second pressure-bearing body 6 and the first pressure-bearing body 5 are fully inserted and engaged. At this time, the sliding locking pins 10 are aligned with the snap-fit ​​holes on the corresponding sliding pressure plate 8. Under the elastic force of the push spring 12, the sliding locking pins 10 engage with the snap-fit ​​grooves 11 on the corresponding sliding pressure plate 8, thereby locking the position of the sliding pressure plate 8.

[0054] As the second pressure-bearing body 6 gradually moves out of the first pressure-bearing body 5, the sliding locking pin 10 drives the sliding pressure-bearing plate 8 away from the corresponding screw 17 until the sliding pressure-bearing plate 8 is blocked by the fixed pressure-bearing plate 7 and the first pressure-bearing body 5. At this point, the sliding pressure-bearing plate 8 stops sliding. As the second pressure-bearing body 6 continues to move away from the first pressure-bearing body 5, the sliding locking pin 10 moves toward the corresponding mounting base 9, compressing the push spring 12 until it is completely disengaged from the corresponding sliding pressure-bearing plate 8. The push spring 12 drives the sliding locking pin 10 to reset. At this time, the distance between the fixed pressure-bearing plate 7 and the corresponding sliding pressure-bearing plate 8 is much larger than the diameter of the screw 17. After the second pressure-bearing body 6 is disengaged from the first pressure-bearing body 5, the first pressure-bearing body 5 can be moved horizontally to disengage the fixed pressure-bearing plate 7 from the gasket 19, making it convenient to remove the assembled heat dissipation components.

[0055] Reference Figure 6 and Figure 7 A limit block 27 is fixed to the inner wall of the guide rail 25 at the wide end of the first pressure bearing body 5 so that the sliding pressure bearing piece 8 will not fall off from the first pressure bearing body 5.

[0056] Reference Figure 6 ,and Figure 7The sliding pressure plate 8 includes a pressure-bearing part 81 and a sliding part 82. The pressure-bearing part 81 is used to abut between the gasket 19 and the heat dissipation workpiece 16. The sliding part 82 is integrally formed at both ends of the pressure-bearing part 81. One end of the sliding part 82 is slidably engaged with the guide rail 25 of the first pressure-bearing body 5, and the other end of the sliding part 82 is used to slidably engage with the sliding cavity 24 in the second pressure-bearing body 6. The snap-fit ​​groove 11 is formed on the sliding part 82 located in the first pressure-bearing body 5. The pressure-bearing part 81 is a rigid sheet. The thickness of both the pressure-bearing part 81 and the fixed pressure plate 7 is less than 2 mm. Furthermore, the surfaces of both the pressure-bearing part 81 and the fixed pressure plate 7 are covered with a polytetrafluoroethylene smooth layer to reduce the moving friction between the gasket 19 and the heat dissipation workpiece 16. Because the pressure-bearing part 81 and the fixed pressure plate 7 have high hardness, smooth surfaces, and thin thickness, it facilitates the separation between the pressure-bearing part 81 and the fixed pressure plate 7.

[0057] Reference Figure 6 and Figure 7 The length of the fixed pressure plate 7 is less than the length of the two sliding pressure plates 8, so that the sliding locking pin 10 will not interfere with the fixed pressure plate 7. The length of the sliding pressure plate 8 near the opening of the first pressure body 5 is less than the length of the sliding pressure plate 8 away from the opening of the first pressure body 5, that is, the length of the sliding pressure plate 8 away from the narrow end of the first pressure body 5 is less than the length of the sliding pressure plate 8 near the narrow end of the first pressure body 5. The guide rail 25 in the first pressure body 5 corresponds one-to-one with the sliding part 82 of the sliding pressure plate 8. Among the sliding locking pins 10 at both ends of the second pressure body 6, the length of the two sliding locking pins 10 away from the opening of the second pressure body 6 is greater than the length of the two sliding locking pins 10 near the opening of the second pressure body 6, so that the two sliding locking pins 10 near the narrow end of the first pressure body 5 will not interfere with the sliding pressure plate 8 away from the narrow end of the first pressure body 5.

[0058] Reference Figure 7 and Figure 8 The mounting base 9 is slidably connected to the corresponding position of the second pressure bearing 6. The sliding direction of the mounting base 9 is parallel to the moving direction when the second pressure bearing 6 and the first pressure bearing 5 are inserted and mated. Supports 29 are fixed at both ends of the second pressure bearing 6, and each support 29 corresponds to the mounting base 9. A return spring 28 is fixed between the support 29 and the mounting base 9. The spring force of the return spring 28 is greater than that of the push spring 12. The return spring 28 allows for the installation of screws 17 of different diameters in the heat dissipation components.

[0059] The implementation principle of Embodiment 2 of this application is as follows: When the four screws 17 are placed in the corresponding limiting holes 2, and the springs 18 and washers 19 are both sleeved on the screws 17, the wide end of the first pressure body 5 is positioned below the pressing body 32 on one side, so that the length direction of the fixed pressure plate 7 is parallel to the length direction of the tooling base 1. Then, the first pressure body 5 is moved so that the two rows of screws 17 are respectively located between the two sets of fixed pressure plates 7 and sliding pressure plates 8. Then, the first pressure body 5 is moved so that the two fixed pressure plates 7 are located between the two sets of fixed pressure plates 7 and sliding pressure plates 8. The screw 17 abuts against the upper surface of the washer 19 and the upper surface of the isolating part of the washer 19, and the side wall of the cylindrical part. Then, the second pressure body 6 is aligned with the first pressure body 5, and the narrow end of the second pressure body 6 is gradually slid into the first pressure body 5. During this process, the ends of the two fixed pressure plates 7 and the two sliding pressure plates 8 away from the first pressure body 5 gradually slide into the sliding cavity 24 of the second pressure body 6. The convex arc surfaces of the sliding locking pins 10 at both ends of the second pressure body 6 first abut against the corresponding sliding pressure plates 8 and move towards the corresponding fixed pressure plates 7. The sliding body 8 moves in the direction of the first pressure body 5 until it abuts against the gasket 19. At this time, the screw 17 and the gasket 19 limit the position of the sliding pressure body 8. As the second pressure body 6 continues to slide, the sliding locking pin 10 moves towards the corresponding mounting base 9, compressing the push spring 12 until the second pressure body 6 and the first pressure body 5 are fully engaged. At this time, the sliding locking pin 10 aligns with the snap-fit ​​groove 11 on the corresponding sliding pressure body 8. Under the elastic force of the push spring 12, the sliding locking pin 10... The corresponding sliding pressure plate 8 is engaged with the snap-fit ​​groove 11 to lock the position of the sliding pressure plate 8. Then, the heat dissipation workpiece 16 is put on the four screws 17. The quick clamp 31 makes the two pressing bodies 32 press down on the first pressure body 5 and the second pressure body 6 respectively. The fixed pressure plate 7 and the sliding pressure plate 8 abut the pad 19 to move down, which compresses the spring 18. The heat dissipation workpiece 16 moves down automatically under its own weight until the groove 22 on the screw 17 is exposed, and the C-type card 20 can be installed.

[0060] After the C-type clip 20 is installed, the pressing body 32 releases the first pressure body 5 and the second pressure body 6. Under the elastic force of the spring 18, the abutment pad 19 and the heat dissipation workpiece 16 move upward until the pad 19 abuts against the C-type clip 20. Then, the second pressure body 6 slides away from the first pressure body 5. The sliding locking pin 10 drives the sliding pressure plate 8 away from the corresponding screw 17 until the sliding pressure plate 8 is blocked by the fixed pressure plate 7 and the limit block 27. The sliding pressure plate 8 stops sliding. As the second pressure body 6 continues to move away from the first pressure body 5, the sliding locking pin 10 moves towards the corresponding mounting base 9, compressing the push spring 12. Then, the sliding locking pin 10 completely disengages from the corresponding sliding pressure plate 8. At this time, the distance between the fixed pressure plate 7 and the corresponding sliding pressure plate 8 is much larger than the diameter of the screw 17 between them. After the second pressure-bearing body 6 separates from the first pressure-bearing body 5, the first pressure-bearing body 5 is moved horizontally so that the upper and lower surfaces of the two fixed pressure-bearing plates 7 are separated from the corresponding gaskets 19 and the heat dissipation workpiece 16. At this time, the distance between the fixed pressure-bearing plate 7 and the corresponding sliding pressure-bearing plate 8 is completely greater than the diameter of the screw 17 between them, and there is no other structure on the bottom wall of the heat dissipation workpiece 16 that interferes with the fixed pressure-bearing plate 7 and the sliding pressure-bearing plate 8. The screw 17 of the assembled heat dissipation component can then be removed from the limiting hole 2, the fixed pressure-bearing plate 7 and the sliding pressure-bearing plate 8 in sequence. In this embodiment, for heat dissipation workpiece 16 with a relatively soft material, pressure can be effectively avoided. In the case where the upper surface of the heat dissipation workpiece 16 has a complex structure, this embodiment can also effectively avoid contact with the complex structure on the heat dissipation workpiece 16, thus avoiding deformation of the heat dissipation workpiece 16.

[0061] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
