Description
A riveting device for electronic heat sinks Technical Field
[0001] This utility model relates to the field of radiator processing technology, and in particular to a riveting device for electronic radiators. Background Technology
[0002] Electronic heat sinks are primarily used for cooling high-power electronic components. They consist of a basic structure and multiple heat dissipation fins mounted on the base. These fins are arranged parallel to each other and spaced apart. The heat generated by the electronic components is conducted to the heat dissipation fins, which then exchange heat with the external environment, effectively helping to dissipate heat from the electronic components. During manufacturing, there are insertion holes between adjacent heat dissipation fins, and rivets are installed in these holes.
[0003] However, existing riveting technology relies heavily on manual operation, resulting in low efficiency. Furthermore, current riveting devices are often bulky, occupying significant floor space and incurring high costs, making them unaffordable for small manufacturers. Therefore, there is a need for a riveting device that can automatically feed and install rivets, is simple to operate and structure, and is relatively low in cost. Summary of the Invention
[0004] The purpose of this utility model is to solve the problems of low efficiency of manual operation in the existing technology, and the fact that the current riveting device is often large in size, occupies a lot of floor space, and is often expensive, which is difficult for ordinary small manufacturers to afford. Therefore, a riveting device for electronic heat sinks is proposed.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] A riveting device for an electronic heat sink includes a heat sink body and a rivet pin, and further includes a base, wherein a placement platform is provided on one side of the top of the base, and the heat sink body is located on the top of the placement platform;
[0007] A feeding mechanism is used to feed rivet pins. The feeding mechanism is located above the base and includes at least one storage cylinder. A bracket is fixedly provided on the top of the base, and the storage cylinder is installed inside the bracket.
[0008] A riveting mechanism is used for installing rivets. The riveting mechanism is located on the top of the base. The riveting mechanism includes a sliding seat and a side seat. The sliding seat is slidably disposed on the top of the base. A groove is provided on one side of the sliding seat. A side groove is opened on the inner wall of one side of the groove. One end of the side seat is slidably disposed inside the side groove. At least one receiving platform is installed on the top of the side seat. The receiving platform is located inside the groove and directly below the storage cylinder.
[0009] In one possible design, the riveting mechanism further includes multiple limiting rods, all of which are fixedly disposed on one inner wall of the side groove. The side seat is slidably sleeved on the outer wall of the limiting rods. A compression spring is sleeved on the outer wall of the limiting rods, and the two ends of the compression spring are respectively fixedly disposed on one inner wall of the side groove and one side of the side seat.
[0010] In one possible design, an electric telescopic rod is fixedly mounted on the top of the base, and the output shaft of the electric telescopic rod is fixedly mounted on one side of the sliding seat.
[0011] In one possible design, a sliding rod is fixedly installed inside the bracket, and the storage cylinder is slidably sleeved on the outer wall of the sliding rod. A threaded rod is provided on one side of the storage cylinder, and one end of the threaded rod rotatably passes through the storage cylinder and cooperates with the outer wall of the sliding rod.
[0012] In one possible design, the receiving platform is slidably mounted on the top of the side seat, and an inner cavity is opened inside the receiving platform. A fixing rod is slidably mounted inside the inner cavity. Multiple through holes are opened on one side of the side seat. One end of the fixing rod slides through the receiving platform and extends into the interior of an adjacent through hole. A tension spring is sleeved on the outer wall of the fixing rod, and the two ends of the tension spring are respectively fixed to the outer wall of the fixing rod and the inner wall of one side of the inner cavity.
[0013] In one possible design, a fixed seat is fixedly provided on the top of the base, and a plurality of top rods are fixedly provided on one side of the fixed seat, with one end of each top rod sliding through the interior of the side groove, and one end of the fixed rod cooperating with the adjacent top rod.
[0014] In this application, during actual use, the operator first stores multiple rivets inside a storage cylinder. When the sliding seat is in the initial position shown in the figure, the rivets will fall from the storage cylinder to the top of the receiving platform. The radiator body is then placed directly on top of the placement platform. The electric telescopic rod is then driven, causing the sliding seat to move. The sliding seat moves the side seat, which in turn moves the receiving platform, causing the rivets to move. As the sliding seat moves, the concave surface on one side of the sliding seat fits against the inner wall of the radiator body, limiting its movement. The side seat then touches one side of the placement platform, stopping the receiving platform from moving. Continuing to drive the sliding seat further causes the inner wall of the sliding seat's groove to push the rivets, thus pressing them into the mounting holes of the radiator body, achieving press riveting. Furthermore, when the sliding seat moves, the rivets inside the storage cylinder will be restricted by the top surface of the sliding seat until the reverse drive resets it. Only then will the next rivet continue to the top of the receiving platform to achieve material feeding. When the model of the radiator body changes, causing the position of the mounting hole to change, the electric telescopic rod can be driven to move the sliding seat to one side of the fixed seat, so that the top rod on one side of the fixed seat is inserted into the through hole, thereby pushing the fixed rod back into the inner cavity. At this time, the receiving platform will be released from the fixation between it and the side seat. Then the receiving platform can be moved to the corresponding position, and the sliding seat can be reset to complete the adjustment. As for the position of the storage cylinder, simply rotate the threaded rod so that it is no longer against the outer wall of the sliding rod, and it can be moved. Then, rotate the threaded rod in the opposite direction to fix it again.
[0015] In this utility model, the riveting device for electronic heat sinks, through the feeding mechanism, can achieve the following: when the receiving platform is in the initial position, the rivet above it will automatically fall to its top to realize feeding. During the riveting operation, the top surface of the sliding seat will automatically seal the bottom of the storage cylinder until the riveting is completed and the receiving platform is reset to the designated position. The storage cylinder located on the receiving platform can be adjusted according to the position of the receiving platform to adapt to different models of heat sink bodies.
[0016] In this utility model, the riveting device for electronic heat sinks can achieve the following by limiting the relative position of the heat sink body during the riveting operation through the riveting mechanism: the riveting mechanism can ensure the stability of the heat sink body. Then, the riveting operation is performed, and the receiving table can be adjusted to press the rivet into the mounting hole at different positions.
[0017] In this utility model, during use, the feeding mechanism and the riveting mechanism respectively realize the automatic feeding and installation of rivets. Not only is the structure relatively simple, but it can also be adjusted according to the mounting holes of different models of radiators, making it more flexible. It has the advantages of simple structure, convenient operation and strong adaptability. Attached Figure Description

Detailed Implementation
[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0024] Example 1
[0025] Referring to Figures 1-2, a riveting device includes: a base 1, a placement platform 3 welded to one side of the top of the base 1, and a radiator body 9 placed on top of the placement platform 3. A feeding mechanism is provided above the base 1 for feeding rivet pins 13. The feeding mechanism includes at least one storage cylinder 5, which contains rivet pins 13. A bracket 4 is bolted to the top of the base 1, and the storage cylinder 5 is installed inside the bracket 4.
[0026] Referring to Figures 3-4, a riveting mechanism is provided on the top of the base 1 for installing the rivet 13. The riveting mechanism includes a sliding seat 2 and a side seat 20. The sliding seat 2 is slidably disposed on the top of the base 1, and a groove is formed on one side of the sliding seat 2. A side groove 17 is formed on the inner wall of one side of the groove. One end of the side seat 20 is slidably disposed inside the side groove 17. At least one receiving platform 12 is installed on the top of the side seat 20. The receiving platform 12 is located inside the groove and directly below the storage cylinder 5. When the rivet 13 in the storage cylinder 5 falls, it will fall onto the receiving platform 12.
[0027] Furthermore, the riveting mechanism also includes multiple limiting rods 16, one end of which is fixed to one inner wall of the side groove 17, and the side seat 20 is slidably sleeved on the outer wall of the limiting rods 16. A compression spring 18 is sleeved on the outer wall of the limiting rods 16, and the two ends of the compression spring 18 are respectively fixed to one inner wall of the side groove 17 and one side of the side seat 20, thereby realizing the reset of the side seat 20.
[0028] Referring to Figure 1, an electric telescopic rod 8 is connected to the top of the base 1, and the output shaft of the electric telescopic rod 8 is connected to one side of the sliding seat 2. When the electric telescopic rod 8 is activated, it will drive the sliding seat 2 to move.
[0029] Specifically, the staff first stores multiple rivets 13 inside the storage cylinder 5. When the sliding seat 2 is in the initial position shown in Figure 3, the rivets 13 will fall from the storage cylinder 5 to the top of the receiving platform 12. The radiator body 9 is then placed directly on the top of the placement platform 3. Subsequently, the electric telescopic rod 8 is driven, which moves the sliding seat 2. The sliding seat 2 moves the side seat 20, which in turn moves the receiving platform 12, causing it to move the rivets 13. As the sliding seat 2 moves, the concave surface on one side of the sliding seat 2 will fit over the radiator body. The inner wall of the radiator body 9 is used to limit its movement. Then, the side seat 20 will touch one side of the placement platform 3, thus stopping the movement of the receiving platform 12 together. At this time, the sliding seat 2 continues to move. The inner wall of the groove of the sliding seat 2 will push the rivet 13 to move, thereby pressing the rivet 13 into the mounting hole of the radiator body 9 to achieve riveting. When the sliding seat 2 moves, the rivet 13 inside the storage cylinder 5 will be restricted by the top surface of the sliding seat 2 until the reverse drive is reset. Then, the next rivet 13 will continue to the top of the receiving platform 12 to achieve material feeding.
[0030] This application can be used in the field of radiator manufacturing, or in other fields applicable to this application.
[0031] Example 2
[0032] Referring to Figure 1, an improvement upon Embodiment 1 is provided: a riveting device for electronic heat sinks, applied in the heat sink manufacturing field. A sliding rod 7 is fixed inside the support 4. A storage cylinder 5 is slidably sleeved on the outer wall of the sliding rod 7. A threaded rod 6 is threadedly connected to one side of the storage cylinder 5. One end of the threaded rod 6 rotatably passes through the storage cylinder 5 and engages with the outer wall of the sliding rod 7. By rotating the threaded rod 6, one end abuts against the outer wall of the sliding rod 7, thereby moving and fixing the storage cylinder 5 to ensure it is above the receiving platform 12.
[0033] Referring to Figure 4, the receiving platform 12 is slidably mounted on the top of the side seat 20. An inner cavity 14 is formed inside the receiving platform 12, and a fixing rod 15 is slidably mounted inside the inner cavity 14. Multiple through holes 19 are formed on one side of the side seat 20. One end of the fixing rod 15 slidably passes through the receiving platform 12 and extends into the interior of an adjacent through hole 19, thereby fixing the receiving platform 12 to the side seat 20. A tension spring is fitted onto the outer wall of the fixing rod 15, and both ends of the tension spring are fixed to the outer wall of the fixing rod 15 and the inner wall of one side of the inner cavity 14, respectively. The tension spring ensures that the fixing rod 15 remains in its original position when no external force is applied.
[0034] The top of the base 1 is bolted to a fixing seat 10, and one side of the fixing seat 10 is bolted to a plurality of push rods 11, and one end of each push rod 11 slides through into the interior of the side groove 17. One end of the fixing rod 15 cooperates with the adjacent push rod 11.
[0035] Specifically, when the model of the radiator body 9 changes, causing a change in the position of the mounting hole, the electric telescopic rod 8 can be driven to move the sliding seat 2 to one side of the fixed seat 10, so that the top rod 11 on one side of the fixed seat 10 is inserted into the through hole 19, thereby pushing the fixed rod 15 back into the inner cavity 14. At this time, the receiving platform 12 will be released from the fixation between itself and the side seat 20, and then the receiving platform 12 can be moved to the corresponding position, and the sliding seat 2 can be reset to complete the adjustment. As for the position of the storage cylinder 5, simply rotate the threaded rod 6 so that it is no longer against the outer wall of the sliding rod 7, and it can be moved. Then, rotate the threaded rod 6 in the opposite direction to fix it again.
[0036] However, as is well known to those skilled in the art, the working principle and wiring method of the electric telescopic pole 8 are commonplace and are all conventional means or common knowledge, so they will not be described in detail here. Those skilled in the art can make any selections according to their needs or convenience.
[0037] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
