Description

Technical Field

[0001] This invention relates to the field of server technology, and in particular to a riveting fixture for a server chassis power supply bracket. Background Technology

[0002] In servers, the power supply is one of the essential components.

[0003] Conventional servers typically use power supply brackets to mount and configure power supplies. For example... Figure 1 , Figure 2 As shown, the overall shape of the power supply bracket is usually "M" shaped, with two cavities inside. It is riveted to the base of the server chassis, and the whole bracket forms two tunnels to slide the power supply components into the two tunnels, so as to realize the sliding plug-in installation of the power supply in the server chassis.

[0004] Currently, the common riveting connection between the power supply bracket and the chassis base uses a drilled and flanged riveting method. For example, 12 riveting points are made on the bottom surface of the chassis base and riveted to the bottom of the power supply bracket, while 4 riveting points are made on the side wall of the chassis base and riveted to the side wall of the power supply bracket. One side of these riveting points is inside the aforementioned tunnel structure, that is, inside the cavity of the power supply bracket. A strong support structure is required for riveting, but due to the narrow space of the tunnel structure, it is difficult to provide strong support.

[0005] In related technologies, the riveting connection between the power supply bracket and the chassis base mainly relies on manual operation, primarily divided into single-point drilling riveting and rivet riveting. In single-point drilling riveting, the chassis base needs to be flipped upside down and placed on a workbench, then hammered from the bottom with tools. Simultaneously, metal blocks and brackets are used for simple support within the tunnel structure of the power supply bracket. This method is cumbersome and inefficient, and the simple support structure provides weak support, typically only able to withstand the pressure of a single-point riveting. This necessitates operating on each riveting point individually, otherwise the bracket is prone to falling apart, resulting in low production efficiency. As for rivet riveting, while it doesn't require support within the tunnel structure, workers need to use rivet guns and other equipment to operate on the outside of the chassis base. Not only is the riveting quality and reliability inferior to drilling riveting, but the entire process is almost entirely manual, resulting in low efficiency and low mechanization.

[0006] Therefore, how to improve the riveting efficiency and quality between the chassis base and the power supply bracket, achieve stable support for the riveting points, reduce manual labor, and improve the degree of mechanization of the operation are technical problems faced by those skilled in the art. Summary of the Invention

[0007] The purpose of this invention is to provide a riveting fixture for server chassis power supply brackets, which can improve the riveting efficiency and quality between the chassis base and the power supply bracket, achieve stable support for the riveting points, reduce manual labor, and improve the degree of mechanization of the operation.

[0008] To solve the above technical problems, the present invention provides a server chassis power supply bracket riveting fixture, including a mounting base plate, a feeding mechanism, a reaction force support mechanism, a side riveting mechanism, and a bottom riveting mechanism;

[0009] The feeding mechanism is set on the mounting base plate and is used to transport the pre-installed chassis base and power supply bracket as a whole to the preset riveting station;

[0010] The reaction force support mechanism is disposed on the mounting base plate and is used to press the bottom plate of the power supply bracket against the bottom surface of the chassis base and the side wall of the power supply bracket against the inner surface of the chassis base after the chassis base and the power supply bracket are delivered to the position.

[0011] The side riveting mechanism is disposed on the mounting base plate and is used to rivet the lateral riveting holes on the side wall of the chassis base after the reaction force support mechanism presses the power bracket tightly.

[0012] The bottom edge riveting mechanism is disposed on the mounting base plate and is used to rivet the vertical riveting holes on the base plate of the chassis after the reaction force support mechanism presses the power supply bracket.

[0013] On the other hand, it also includes a floating support plate that can be vertically floating on the mounting base plate, and the feeding mechanism and the side riveting mechanism are both disposed on the floating support plate.

[0014] On the other hand, the feeding mechanism includes a driving component disposed on the floating support plate and a feeding tray connected to the output end of the driving component. The feeding tray is movably disposed on the top surface of the floating support plate, and the driving component is used to drive the feeding tray to move linearly in a preset direction.

[0015] On the other hand, the feeding mechanism also includes a plurality of limiting plates disposed on the floating support plate, each of the limiting plates being used to abut against the corresponding side of the feeding tray to stop the feeding tray at a preset riveting position.

[0016] On the other hand, the side riveting mechanism includes a guide mounting seat disposed on the top surface of the floating support plate, a horizontal sliding plate slidably disposed in the guide mounting seat, and a horizontal riveting punch protruding from the inner end face of the horizontal sliding plate. The sliding direction of the horizontal sliding plate is horizontal and perpendicular to the feeding direction of the feeding mechanism. The horizontal riveting punch is used to rivet the side riveting hole.

[0017] On the other hand, the side riveting mechanism also includes a first driving block erected on the top surface of the mounting base plate. The first driving block has a first inclined surface on its end face facing the horizontal sliding plate. The outer end of the horizontal sliding plate has a first abutting surface for cooperating with the first inclined surface, so that when the floating support plate descends vertically, the horizontal sliding plate is driven to move horizontally by the abutting force between the first inclined surface and the first abutting surface.

[0018] On the other hand, the bottom edge riveting mechanism includes a plurality of vertical riveting punches, each of which is vertically erected on the top surface of the mounting base plate and is embedded in the through hole of the floating support plate.

[0019] On the other hand, a riveting pad is provided on the top surface of the floating support plate at the corresponding position of the bottom edge riveting mechanism, and the top of each vertical riveting punch is embedded in the through hole of the riveting pad.

[0020] The top surface of the feeding tray of the feeding mechanism is flush with the top surface of the riveting pad.

[0021] On the other hand, the top surface of the floating support plate is embedded with a plurality of rollers, each of which is used to form rolling friction with the bottom surface of the feeding tray of the feeding mechanism.

[0022] On the other hand, the reaction force support mechanism includes a vertical pressing assembly for pressing the bottom plate of the power supply bracket against the bottom surface of the chassis base, a lateral pressing assembly for pressing the side wall of the power supply bracket against the inner surface of the chassis base, and a pressing drive assembly for driving the vertical pressing assembly and the lateral pressing assembly to perform corresponding pressing actions respectively.

[0023] The vertical clamping assembly includes a mounting base disposed on the top surface of the mounting base plate, a floating spring erected on the top surface of the mounting base, a floating bracket disposed on the top of the floating spring, and a vertical clamping arm with one end connected to the floating bracket and the other end extending along the feeding direction of the feeding mechanism. The vertical clamping arm is used to insert into the through hole of the power supply bracket and clamp the base plate of the power supply bracket.

[0024] The lateral clamping assembly includes a movable base movably disposed on the top surface of the floating support plate and a lateral clamping arm disposed on the movable base. The moving direction of the movable base is perpendicular to the feeding direction of the feeding mechanism. The lateral clamping arm is parallel to the vertical clamping arm and is used to insert into the through hole of the power supply bracket and clamp the side wall of the power supply bracket.

[0025] On the other hand, the pressing drive assembly includes a vertically movable top plate, a first abutment block, a second abutment block, a third abutment block, and a drive abutment block;

[0026] The first abutting block and the second abutting block are both disposed on the bottom surface of the top plate, and are respectively used to form abutments with the top surfaces of the two ends of the vertical pressing arm in the length direction;

[0027] The third abutment block is disposed on the bottom surface of the top plate and is used to abut against the end face of the extension end of the lateral clamping arm;

[0028] The lateral clamping assembly further includes a second driving block disposed on the movable base. The top end of the second driving block has a second inclined surface, and the bottom end of the driving abutment block has a second abutment surface. The second inclined surface is used to cooperate with the second abutment surface so that when the top plate descends vertically, the abutment force between the second inclined surface and the second abutment surface drives the movable base to move horizontally.

[0029] The server chassis power supply bracket riveting fixture provided by this invention mainly includes a mounting base plate, a loading mechanism, a reaction support mechanism, a side riveting mechanism, and a bottom riveting mechanism. The mounting base plate is the main component of this fixture and is primarily used for mounting the remaining parts. The loading mechanism is located on the mounting base plate and is mainly used to transport the pre-assembled chassis base and power supply bracket to the preset riveting position on the mounting base plate to perform the loading operation. The reaction support mechanism is located on the mounting base plate and is mainly used to press the bottom plate of the power supply bracket onto the bottom surface of the chassis base after the loading mechanism has transported the chassis base and power supply bracket into place, thereby forming a stable reaction support for the bottom plate of the power supply bracket and the bottom surface of the chassis base; simultaneously, the reaction support mechanism also presses the side wall of the power supply bracket onto the inner surface of the chassis base, thereby forming a stable reaction support for the side wall of the power supply bracket and the inner surface of the chassis base. The side riveting mechanism is installed on the mounting base plate. It is mainly used to rivet the side walls of the power supply bracket to the lateral riveting holes on the side walls of the chassis base after the reaction support mechanism has pressed the side walls of the power supply bracket together, thus achieving the riveting fixation between the side walls of the power supply bracket and the side walls of the chassis base. Similarly, the bottom riveting mechanism is also installed on the mounting base plate. It is mainly used to rivet the bottom plates of the chassis base to the vertical riveting holes after the reaction support mechanism has pressed the bottom plates of the power supply bracket together, thus achieving the riveting fixation between the bottom plates of the power supply bracket and the bottom plates of the chassis base.

[0030] Thus, the server chassis power supply bracket riveting fixture provided by this invention, when riveting the chassis base and power supply bracket, firstly, a feeding mechanism transports the pre-assembled chassis base and power supply bracket to a preset riveting station. Then, a reaction force support mechanism presses the bottom plate and side wall of the power supply bracket together. Finally, a side riveting mechanism rivets the lateral riveting holes of the chassis base, and a bottom riveting mechanism rivets the vertical riveting holes of the chassis base, thereby achieving vertical and lateral riveting fixation of the chassis base and power supply bracket, completing the riveting connection operation. During this process, the reaction force support mechanism mainly provides support for the bottom plate and side wall of the mounting bracket, eliminating the need for simple manual support. The support force is strengthened, allowing for convenient riveting using the hole-drawing riveting process. Furthermore, the entire riveting operation requires virtually no manual labor, thus improving the riveting efficiency and quality between the chassis base and power supply bracket, achieving stable support for the riveting points, reducing manual labor, and increasing the degree of mechanization.

[0057] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0058] Please refer to Figure 3 , Figure 3 This is a schematic diagram of the overall structure of a specific embodiment of the present invention.

[0059] In one specific embodiment of the present invention, the server chassis power supply bracket riveting fixture mainly includes a mounting base plate 3, a feeding mechanism 4, a reaction force support mechanism 5, a side riveting mechanism 6, and a bottom riveting mechanism 7.

[0060] Among them, the mounting base plate 3 is the main component of this fixture, mainly used for installing the other parts.

[0061] The loading mechanism 4 is set on the mounting base plate 3 and is mainly used to transport the pre-installed chassis base 1 and power supply bracket 2 as a whole to the preset riveting station on the mounting base plate 3 to realize the loading operation.

[0062] The reaction support mechanism 5 is installed on the mounting base plate 3. It is mainly used to press the bottom plate of the power support 2 onto the bottom surface of the chassis base 1 after the loading mechanism 4 has transported the chassis base 1 and the power support bracket 2 into place, thereby forming a stable reaction support for the bottom plate of the power support 2 and the bottom surface of the chassis base 1. At the same time, the reaction support mechanism 5 also presses the side wall of the power support 2 onto the inner side surface of the chassis base 1, thereby forming a stable reaction support for the side wall of the power support 2 and the inner side surface of the chassis base 1.

[0063] The side riveting mechanism 6 is set on the mounting base plate 3. It is mainly used to rivet the side riveting holes 11 on the side wall of the chassis base 1 after the reaction force support mechanism 5 presses the side wall of the power supply bracket 2 tightly, thereby realizing the riveting and fixing between the side wall of the power supply bracket 2 and the side wall of the chassis base 1.

[0064] Similarly, the bottom edge riveting mechanism 7 is also set on the mounting base plate 3. It is mainly used to rivet the vertical riveting holes 12 on the base plate of the chassis base 1 after the reaction force support mechanism 5 presses the base plate of the power supply bracket 2 tightly, thereby realizing the riveting and fixing between the base plate of the power supply bracket 2 and the base plate of the chassis base plate.

[0065] Thus, the server chassis power supply bracket riveting fixture provided in this embodiment, when riveting the chassis base 1 and the power supply bracket 2, firstly, the pre-assembled chassis base 1 and power supply bracket 2 are transported to the preset riveting station by the feeding mechanism 4. Then, the bottom plate and side wall of the power supply bracket 2 are pressed together by the reaction support mechanism 5. Finally, the side riveting mechanism 6 is used to rivet the side riveting holes 11 of the chassis base 1, and the bottom riveting mechanism 7 is used to rivet the vertical riveting holes 12 of the chassis base 1, thereby realizing the riveting and fixing of the chassis base 1 and the power supply bracket 2 in the vertical and lateral directions, and completing the riveting connection operation. During this period, the reaction support mechanism 5 mainly supports the base plate and side wall of the mounting bracket, eliminating the need for simple manual support. The support force is strengthened, and the riveting process can be easily used for riveting. Moreover, the entire riveting operation basically does not require manual operation. Therefore, it can improve the riveting efficiency and quality between the chassis base 1 and the power supply bracket 2, achieve stable support for the riveting point, reduce manual labor, and improve the degree of mechanization of the operation.

[0066] Considering that the bottom edge riveting mechanism 7 is located on the mounting base plate 3, and the reaction force support mechanism 5 needs to press the base plate of the power supply bracket 2 firmly against the bottom surface of the chassis during operation, a floating support plate 8 is added in this embodiment to facilitate the riveting operation of the bottom edge riveting mechanism 7 on the vertical riveting holes 12 of the chassis base 1. Specifically, the floating support plate 8 is located above the mounting base plate 3 and is connected to the mounting base plate 3 through elastic elements such as springs, thereby achieving an elastic connection and enabling vertical elastic lifting and lowering movement. Correspondingly, the feeding mechanism 4 is set on the floating support plate 8. Since the bottom plate of the power supply bracket 2 is pressed by the reaction support mechanism 5, the floating support plate 8 is elastically compressed, and the position of the side riveting hole 11 of the chassis base 1 is also lowered accordingly. Therefore, in order to ensure the normal riveting operation of the side riveting mechanism 6 on the side riveting hole 11, in this embodiment, the side riveting mechanism 6 is also set on the floating support plate 8 so as to float synchronously with the floating support plate 8, and ensure that the position of the side riveting mechanism 6 and the side riveting hole 11 on the chassis base 1 remains relatively fixed.

[0067] like Figure 7 As shown, Figure 7 for Figure 3 The diagram shows the structure without the chassis base 1 and power supply bracket 2 installed.

[0068] In one specific embodiment of the feeding mechanism 4, the feeding mechanism 4 mainly includes a driving component 41 and a feeding tray 42. The driving component 41 is mounted on the floating support plate 8 and can specifically be a drive motor, drive cylinder, or other components, generally located at one end of the floating support plate 8 along its length. The feeding tray 42 is connected to the output end of the driving component 41, for example, to the telescopic rod of the drive cylinder, and a sliding connection is formed between the feeding tray 42 and the floating support plate 8, allowing the feeding tray 42 to slide on the surface of the floating support plate 8. The main function of the driving component 41 is to drive the feeding tray 42 to move linearly along a preset direction on the surface of the floating support plate 8. Generally, the direction of movement of the feeding tray 42 is parallel to the length direction of the floating support plate 8. The specific stroke of the feeding tray 42 is related to the driving component 41. For example, when the driving component 41 is a drive cylinder, when the telescopic rod is fully retracted, the feeding tray 42 is in its initial position, i.e., the receiving position; when the telescopic rod is fully extended, the feeding tray 42 reaches the preset position, i.e., the riveting position. With this configuration, the initial position and target position of the loading tray 42 can be easily switched simply by reciprocating the output of the drive component 41.

[0069] Furthermore, to ensure that the feeding mechanism 4 can accurately transport the chassis base 1 and power supply bracket 2 to the riveting station, a limiting plate 43 is added in this embodiment. Specifically, the limiting plate 43 is specifically set on the floating support plate 8, such as on the side wall or top surface of the floating support plate 8. It is mainly used to form an abutment with the corresponding side of the feeding tray 42, such as abutting with one side of the feeding tray 42 along its length, thereby limiting the transport position of the feeding tray 42 and stopping the feeding tray 42 at the preset riveting station. This ensures the accuracy of the feeding position of the chassis base 1 and power supply bracket 2, prevents deviations in the feeding position during long-term operation, and facilitates accurate subsequent riveting operations.

[0070] In one specific embodiment of the limiting plate 43, in addition to being used to abut against the loading pallet 42 to stop it at the riveting station, multiple limiting plates 43 can be provided at the same time so that some of the limiting plates 43 can also abut against the side wall of the loading pallet 42, thereby guiding the sliding movement of the loading pallet 42 on the top surface of the floating support plate 8 and further improving the loading position accuracy of the loading pallet 42.

[0071] like Figure 5 As shown, Figure 5 for Figure 4 A top view of a partial structure.

[0072] In one specific embodiment of the side riveting mechanism 6, the side riveting mechanism 6 mainly includes a guide mounting seat 61, a horizontal sliding plate 62, and a horizontal riveting punch 63. Specifically, the guide mounting seat 61 is disposed on the top surface of the floating support plate 8, generally located on the side of the floating support plate 8. The horizontal sliding plate 62 is disposed within the guide mounting seat 61 and forms a sliding connection, enabling it to slide linearly along the guiding direction of the guide mounting seat 61, and its movement direction is specifically perpendicular to the side wall of the chassis base 1, that is, perpendicular to the feeding direction of the feeding mechanism 4. The horizontal riveting punch 63 protrudes from the inner end face of the horizontal sliding plate 62, close to the side wall of the chassis base 1, and is mainly used to insert into the lateral riveting hole 11 after the inner side wall of the power supply bracket 2 is pressed by the reaction force support mechanism 5, as the horizontal sliding plate 62 moves towards the side wall of the chassis base 1, to perform the riveting operation on the lateral riveting hole 11. Multiple horizontal riveting punches 63 can be set at the same time. After the loading tray 42 transports the chassis base 1 and power support 2 into place, each horizontal riveting punch 63 is aligned with each lateral riveting hole 11 on the side wall of the chassis base 1.

[0073] like Figure 11 As shown, Figure 11 This is a schematic diagram of the mating structure between the first contact surface 621 and the first inclined surface 641.

[0074] To facilitate the automatic sliding movement of the horizontal sliding plate 62 and the engagement of the horizontal riveting punch 63 with the side riveting hole 11, a first driving block 64 is added in this embodiment. Specifically, the first driving block 64 is erected on the top surface of the mounting base plate 3, passes upward through and protrudes above the floating support plate 8, and extends upward to the height of the horizontal sliding plate 62. A first inclined surface 641 is formed on the end face of the first driving block 64 facing the horizontal sliding plate 62. Correspondingly, a first abutting surface 621 is provided on the outer end of the horizontal sliding plate 62. The first abutting surface 621 is mainly used to cooperate with the first inclined surface 641 on the first driving block 64. When the floating support plate 8 produces a vertical downward movement, the horizontal component of the abutting force between the first inclined surface 641 and the first abutting surface 621 drives the horizontal sliding plate 62, driving the horizontal sliding plate 62 to slide towards the chassis base 1 in the guide mounting seat 61, thereby realizing the automatic sliding of the horizontal sliding plate 62 and the automatic cooperation between the horizontal riveting punch 63 and the side riveting hole 11.

[0075] In addition, after the riveting operation of the lateral riveting hole 11 is completed, a first return spring 65 is added in this embodiment to facilitate the automatic reset sliding of the horizontal sliding plate 62. Specifically, one end of the first return spring 65 is connected to the mounting base plate 3, and the other end is connected to the horizontal sliding plate 62. It can generally be embedded inside the horizontal sliding plate 62, and the elastic deformation direction of the first return spring 65 is the movement direction of the horizontal sliding plate 62. Thus, when the horizontal sliding plate 62 moves toward the side wall of the chassis base 1, the first return spring 65 is compressed to accumulate elastic potential energy. After the riveting operation is completed, the first return spring 65 elastically resets, and uses the elastic force to form a reverse driving force on the horizontal sliding plate 62, so that the horizontal sliding plate 62 slides back to the initial position, which is convenient for the next riveting operation.

[0076] like Figure 9 As shown, Figure 9 This is a schematic diagram of the bottom edge riveting mechanism 7.

[0077] In one specific embodiment of the bottom edge riveting mechanism 7, the bottom edge riveting mechanism 7 mainly includes multiple vertical riveting punches 71. Specifically, each vertical riveting punch 71 is vertically erected on the top surface of the mounting base plate 3 and extends vertically upward. Simultaneously, each vertical riveting punch 71 is embedded in the through hole of the floating support plate 8, achieving a concealed design. With this configuration, before the reaction support mechanism 5 presses the bottom plate of the power supply bracket 2, the floating support plate 8 does not descend. At this time, each vertical riveting punch 71 is also embedded in the through hole of the floating support plate 8 and does not engage with the vertical riveting hole 12 of the chassis base 1. When the reaction support mechanism 5 presses the bottom plate of the power supply bracket 2, the floating support plate 8 descends accordingly. At this time, the top of each vertical riveting punch 71 protrudes from the top surface of the floating support plate 8 and engages with the vertical riveting hole 12 of the chassis base 1, thus facilitating subsequent riveting operations.

[0078] Furthermore, considering that both the chassis base 1 and the power supply bracket 2 are placed within the loading tray 42 of the loading mechanism 4, and that the loading tray 42 has a certain thickness (height), a riveting pad 81 is added in this embodiment to avoid interference. Specifically, the riveting pad 81 is set on the top surface of the floating support plate 8, generally located at a corner of the floating support plate 8, and has a certain thickness, which is comparable to the thickness of the loading tray 42. The tops of each vertical riveting punch 71 are embedded in the through holes of the riveting pad 81. At the same time, the shape of the loading tray 42 matches the shape of the riveting pad 81, and the two can be spliced ​​together into a whole, that is, spliced ​​into the same shape as the floating support plate 8. With this configuration, when the loading tray 42 moves into position, it will be spliced ​​together with the riveting pad 81, avoiding interference from the riveting pad 81 on the movement of the loading tray 42. At the same time, when the reaction force support mechanism 5 presses the bottom plate of the power supply bracket 2, the floating support plate 8, the riveting pad 81 and the loading tray 42 descend together. At this time, the top of each riveting punch protrudes from the riveting top plate 531, which can smoothly cooperate with the vertical riveting hole 12 of the chassis base 1.

[0079] like Figure 8 As shown, Figure 8 for Figure 4 The diagram shown omits the loading tray 42.

[0080] To facilitate the sliding of the loading pallet 42 on the top surface of the floating support plate 8, this embodiment also adds multiple rollers 82 to the top surface of the floating support plate 8. Specifically, each roller 82 is embedded in the top surface of the floating support plate 8, and the highest point of each roller 82 is flush with or slightly higher than the top surface of the floating support plate 8. These rollers primarily engage with the top surface of the loading pallet 42 to generate rolling friction, thereby enabling the loading pallet 42 to roll on the top surface of the floating support plate 8. This configuration not only improves the smoothness of the movement of the loading mechanism 4 during loading or resetting movements but also reduces wear on the contact surfaces and decreases noise.

[0081] like Figure 4 As shown, Figure 4 for Figure 3 Another perspective illustration.

[0082] In one specific embodiment of the reaction support mechanism 5, the reaction support mechanism 5 mainly includes a vertical clamping assembly 51, a lateral clamping assembly 52, and a clamping drive assembly 53. The vertical clamping assembly 51 is mainly used to clamp the base plate of the power supply bracket 2 onto the bottom surface of the chassis base 1, while the lateral clamping assembly 52 is mainly used to clamp the side wall of the power supply bracket 2 onto the inner surface of the chassis base 1. The clamping drive assembly 53 is mainly used to drive the vertical clamping assembly 51 and the lateral clamping assembly 52 to perform corresponding clamping actions.

[0083] Specifically, the vertical clamping assembly 51 mainly includes a mounting base 511, a floating spring 512, a floating bracket 513, and a vertical clamping arm 514. The mounting base 511 is disposed on the top surface of the mounting base plate 3. The floating springs 512 are disposed on the top surface of the mounting base 511 and extend vertically upwards, possessing elasticity, and multiple springs can be disposed simultaneously. The floating brackets 513 are disposed on top of each floating spring 512 and connected to the floating springs 512, achieving vertical floating through the elastic deformation of the floating springs 512. The vertical clamping arm 514 is the core component; one end is connected to the floating bracket 513, and the other end extends along the feeding direction of the feeding mechanism 4, that is, along the length direction of the floating support plate 8 for a predetermined length, extending to the top of the floating support plate 8 or the top of the bottom edge riveting mechanism 7. After the feeding mechanism 4 delivers the chassis base 1 and power support bracket 2 into place, the vertical clamping arm 514 will be inserted into one of the tunnel structures of the power support bracket 2. It is mainly used to perform vertical descent under the driving action of the clamping drive assembly 53, thereby pressing the bottom plate of the power support bracket 2 downward, and then driving the floating support plate 8 to produce vertical descent until the vertical riveting punch 71 protrudes from the riveting pad 81.

[0084] Similarly, the lateral clamping assembly 52 mainly includes a movable base 521 and a lateral clamping arm 522. The movable base 521 is mounted on the top surface of the floating support plate 8 and is slidably connected to it, possessing a degree of freedom of sliding motion. Its direction of movement is perpendicular to the feeding direction of the feeding mechanism 4, i.e., perpendicular to the length of the floating support plate 8, or perpendicular to the side wall of the chassis base 1 after it has been transported to its position. The lateral clamping arm 522 is the core component. One end is connected to the movable base 521, and the other end extends along the feeding direction of the feeding mechanism 4, i.e., along the length of the floating support plate 8 for a predetermined length, extending to the top of the floating support plate 8. After the feeding mechanism 4 transports the chassis base 1 and the power supply bracket 2 to their positions, the lateral clamping arm 522 inserts into another tunnel structure of the power supply bracket 2. It is mainly used for horizontal lateral movement under the driving action of the clamping drive assembly 53, thereby pressing the side wall of the power supply bracket 2 against the inner side of the chassis base 1, thus securing the side wall of the power supply bracket 2. Of course, the horizontal riveting punch 63 in the side riveting mechanism 6 also moves synchronously toward the side riveting hole 11 on the chassis base 1.

[0085] like Figure 10 As shown, Figure 10 This is a schematic diagram of the specific structure of the clamping drive assembly 53.

[0086] In one specific embodiment of the clamping drive assembly 53, the clamping drive assembly 53 mainly includes a top plate 531, a first abutting block 532, a second abutting block 533, a third abutting block 534, and a driving abutting block 535.

[0087] The top plate 531 is the main component, and its shape can be the same as that of the mounting base plate 3. Simultaneously, the top plate 531, as the main body of the pressing drive assembly 53, has vertical lifting freedom, thereby generating the driving action. Generally, the top surface of the top plate 531 can be connected to components such as the stamping head via a power connector to achieve vertical stamping action.

[0088] The first abutting block 532 and the second abutting block 533 are both set on the bottom surface of the top plate 531. Their specific distribution positions correspond to the setting positions of the vertical pressing arm 514. They are mainly used to abut against the two ends of the vertical pressing arm 514 in the length direction when the top plate 531 descends, thereby simultaneously generating a downward driving force on both ends of the vertical pressing arm 514, thereby driving the vertical pressing arm 514 to move downward and press the bottom plate of the power supply bracket 2.

[0089] The third abutment block 534 is disposed on the bottom surface of the top plate 531, and its specific distribution position corresponds to the end position of the extension end of the lateral pressing arm 522. It is mainly used to form a tight abutment with the end face of the extension end of the lateral pressing arm 522 when the top plate 531 descends, so that both ends of the lateral pressing arm 522 are supported, thereby improving the structural strength of the lateral pressing arm 522 and helping to provide greater support reaction force.

[0090] like Figure 6 As shown, Figure 6 This is a schematic diagram of the cooperation structure between the second driving block 523 and the driving abutment block 535.

[0091] The drive abutment block 535 is mainly used to drive the movable base 521 in the lateral pressing assembly 52 to move horizontally, that is, to drive the lateral pressing arm 522 to move. Specifically, in this embodiment, a second drive block 523 is also added to the lateral pressing assembly 52. ​​The second drive block 523 is erected on the top surface of the movable base 521, and a second inclined surface 5231 is formed at the top of the second drive block 523. Correspondingly, the drive abutment block 535 is set on the bottom surface of the top plate 531, and its specific distribution position corresponds to the position of the second drive block 523. A second abutment surface 5351 is formed at the bottom end of the drive abutment block 535. When the top plate 531 descends, the second abutting surface 5351 of the drive abutting block 535 gradually abuts against the second inclined surface 5231 of the second drive block 523, thereby using the horizontal component of the abutting force between the two to generate a driving force on the moving base 521, driving the moving base 521 to move horizontally, and then driving the lateral clamping arm 522 to press the inner wall of the power bracket 2.

[0092] In addition, after the riveting operation of the lateral rivet hole 11 is completed, a second return spring 524 is added in this embodiment to facilitate the automatic reset movement of the lateral clamping arm 522. Specifically, one end of the second return spring 524 is connected to the mounting base 3, and the other end is connected to the movable base 521. It can generally be embedded inside the movable base 521, and the elastic deformation direction of the second return spring 524 is the movement direction of the movable base 521. Thus, when the movable base 521 and the lateral clamping arm 522 move toward the inner wall of the power bracket 2, the second return spring 524 is compressed to accumulate elastic potential energy. After the riveting operation is completed, the second return spring 524 elastically resets, and uses the elastic force to form a reverse driving force on the movable base 521, so that the movable base 521 and the lateral clamping arm 522 slide back to the initial position, which is convenient for the next riveting operation.

[0093] Furthermore, during the operation of the top plate 531, it requires continuous vertical lifting and lowering movements. To improve the accuracy and reliability of these movements, this embodiment adds positioning sleeves 31 and positioning connecting posts 536. The positioning sleeves 31 are mounted on the mounting base plate 3, typically located at various corners, such as four. The positioning connecting posts 536 are positioned on the bottom surface of the top plate 531, with their specific locations corresponding to the distribution of the positioning sleeves 31. They engage with the positioning sleeves 31, guiding the lifting and lowering movements of the positioning connecting posts 536, and consequently guiding the overall lifting and lowering movement of the top plate 531. With this configuration, during the operation of the top plate 531, whether rising or falling, the positioning connecting posts 536 always maintain an engagement with the positioning sleeves 31, ensuring consistent guidance and guaranteeing the long-term stable reciprocating movement of the top plate 531.

[0094] Furthermore, considering that if the top plate 531 is connected to a mechanical power source such as a stamping machine, the impact force of each positioning connecting post 536 on each positioning sleeve 31 and mounting base plate 3 may be relatively strong, in this embodiment, elastic elements, such as damping springs, are embedded in each positioning connecting post 536, or the positioning connecting post 536 itself is an elastic element. With this configuration, during each vertical descent impact stroke of the top plate 531, vibration energy can be absorbed through the elastic deformation of the elastic elements or the positioning connecting post 536 itself, thereby reducing the impact force, mitigating the impact vibration, and improving service life.

Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the invention.
