Description

Technical Field

[0001] This invention relates to the field of riveting equipment technology, and in particular to a riveting mechanism. Background Technology

[0002] In the field of riveting, existing riveting mechanisms generally use fixed carriers to place the workpiece to be riveted. However, as industrial manufacturing develops towards higher precision, higher quality, and higher requirements for product protection, existing fixed carriers have revealed many shortcomings. Due to their stationary nature, they cannot buffer the instantaneous impact force when the pressure device applies pressure. This can easily damage fragile workpieces such as precision electronic components, leading to an increase in product scrap rate. Furthermore, the fixed carrier mechanism is subjected to rigid impacts for a long time, making its own structure prone to fatigue and deformation, reducing the service life of the equipment. At the same time, the lack of buffering can also cause the riveting cutter head to vibrate and displace at the moment of contact with the workpiece, affecting the accuracy of the riveting position and hindering the implementation of high-precision riveting operations, thus limiting the application of riveting technology in more precision manufacturing fields. Summary of the Invention

[0003] The main objective of this invention is to provide a riveting mechanism that addresses the technical problem that existing riveting mechanisms use a fixed carrier mechanism for placing the workpiece to be riveted, which makes it impossible to buffer the instantaneous impact force when the pressure device applies pressure, resulting in damage to the carrier mechanism itself, easy damage to the workpiece, and affecting the riveting accuracy of the workpiece.

[0004] To achieve the above-mentioned objectives, the present invention provides a riveting mechanism, including a fixed bracket, a riveting guide device, and a carrier device;

[0005] The carrier device is mounted on the fixed bracket and is used to support the workpiece to be riveted.

[0006] The riveting guide device is mounted on the fixed bracket and is positioned opposite to the carrier device. The riveting guide device is used to provide riveting force and apply pressure to the workpiece to be riveted. When the riveting guide device applies pressure to the workpiece to be riveted placed on the carrier device, the carrier device generates a buffering force along the movement extension direction of the riveting guide device.

[0007] Furthermore, the fixed bracket includes a base plate, a first support plate, and a support frame assembly. The first support plate and the support frame assembly are respectively disposed on the base plate, and a specified interval is formed between the first support plate and the support frame assembly. The vehicle device is disposed on the first support plate and the support frame assembly, and the central axis of the vehicle device is located within the specified interval.

[0008] Furthermore, the vehicle device includes a first buffer pillar and a buffer seat assembly. The first buffer pillar is detachably connected to the first support plate and the support frame assembly. The buffer seat assembly is disposed on the buffer pillar. The buffer seat assembly forms a specified distance with the first support plate and the support frame assembly, respectively, and the top end of the buffer pillar forms a height difference with the top end of the buffer seat assembly.

[0009] Furthermore, the buffer seat assembly includes a second support plate, a third support plate, and a second buffer support column. The second support plate is fixedly connected to the first buffer support column, and the third support plate is connected to the first support plate through the second buffer support column. The third support plate is located at the end of the second support plate near the pressing and guiding device, and the third support plate is movably connected to the first buffer support column. When the third support plate is subjected to the force of the pressing and guiding device, the third support plate moves downward through the second buffer support column to buffer the movement.

[0010] Furthermore, the first buffer support includes a fixing part and a first buffer part. The fixing part passes through the second support plate and is disposed on the first support plate and the support frame assembly. The first buffer part is slidably connected to the end of the fixing part away from the second support plate, and the first buffer part passes through the third support plate. A limiting piece is provided at the end of the first buffer part near the riveting guide device, and the limiting piece is in contact with the third support plate.

[0011] Furthermore, the third support plate is provided with a receiving groove, and the buffer seat assembly also includes a fourth support plate. The fourth support plate is detachably connected to the receiving groove, and the end of the fourth support plate near the limiting piece is in contact with the limiting piece. The top end of the fourth support plate is located on the same plane as the top end of the third support plate.

[0012] Furthermore, the riveting mechanism also includes a detection device. One end of the third support plate is provided with an extension plate, and the extension plate is provided with a through hole. The detection device is disposed on the support frame assembly and is arranged correspondingly to the first buffer support column. The detection device is used to collect the buffer trajectory of the first buffer support column and the buffer seat assembly, and to collect the movement trajectory of the riveting guide device through the through hole.

[0013] Furthermore, the support frame assembly includes an end plate, a fifth support plate, and at least two side plates. The side plates and the end plate are disposed on the base plate, and the end of the side plate away from the first support plate is connected to the end plate. The side plate is provided with a support platform recessed towards the end plate, and the fifth support plate is disposed on the support platform for supporting the vehicle device.

[0014] Furthermore, the support frame assembly also includes a top plate, and the riveting guide device includes a pressure cylinder and a guide rod. The top plate is disposed at the end of the side plate away from the bottom plate, and the top plate, the end plate, and the side plate together form a placement groove. The pressure cylinder and the guide rod are spaced apart in the placement groove along the length direction of the placement groove, and the end of the pressure cylinder and the guide rod that passes through the top plate are connected by a connecting plate, so that the guide rod moves synchronously with the output shaft of the pressure cylinder through the connecting plate.

[0015] Furthermore, the riveting guide device also includes a pressing cutter head assembly, which includes a connecting block and a cutter head body. The connecting block is detachably connected to the end of the connecting plate away from the pressure cylinder, and the cutter head body is located at the end of the connecting block away from the connecting plate. The centers of the cutter head body, the connecting block, the pressure cylinder, and the carrier device are located on the same axis.

[0016] Beneficial effects:

[0017] A riveting mechanism of the present invention includes a fixed bracket, a riveting guide device, and a carrier device; the carrier device is disposed on the fixed bracket and is used to carry the workpiece to be riveted; the riveting guide device is disposed on the fixed bracket and is disposed opposite to the carrier device; the riveting guide device is used to provide riveting force and apply pressure to the workpiece to be riveted; when the riveting guide device applies pressure to the workpiece to be riveted placed on the carrier device, the carrier device generates a buffering force along the movement extension direction of the riveting guide device. Therefore, by generating a buffering force under pressure, the carrier device can effectively absorb the instantaneous impact force generated when the riveting guide device applies pressure. This ensures that during the riveting process, the impact force is not directly transmitted to the workpiece, but is gradually reduced by the first buffer part of the carrier device. This prevents the workpiece from cracking, deforming, or being damaged due to excessive impact force, thereby reducing the scrap rate and improving the product qualification rate. At the same time, it effectively reduces the peak impact force borne by the carrier device itself during each riveting, reduces the fatigue rate of the carrier device structure, and extends the service life of the entire riveting mechanism. In addition, the buffering force can suppress the vibration and displacement caused by the impact force, allowing the riveting cutter head to apply pressure to the workpiece more accurately, improving the positional accuracy and connection quality of the riveting.

[0039] Reference Figures 1-4 This embodiment provides a riveting mechanism, including a fixed bracket, a riveting guide device 2, and a carrier device 3;

[0040] The carrier device 3 is mounted on the fixed bracket and is used to support the workpiece to be riveted.

[0041] The riveting guide device 2 is mounted on the fixed bracket and is positioned opposite to the carrier device 3. The riveting guide device 2 is used to provide riveting force and apply pressure to the workpiece to be riveted. When the riveting guide device 2 applies pressure to the workpiece to be riveted placed on the carrier device 3, the carrier device 3 generates a buffering force along the movement extension direction of the riveting guide device 2.

[0042] In the above embodiments, the riveting mechanism includes a fixed bracket, a riveting guide device 2, and a carrier device 3. The fixed bracket serves as the basic support structure for the entire riveting mechanism, providing a stable installation position for the riveting guide device 2 and the carrier device 3, ensuring that the components do not shift or shake during the riveting process, and ensuring that the riveting force can be accurately transmitted and applied. The riveting guide device 2 and the carrier device 3 are arranged opposite to each other on the fixed bracket. The carrier device 3 is used to support the workpiece to be riveted, providing a stable placement platform for the workpiece. The main function of the riveting guide device 2 is to provide precise riveting force and apply this force to the workpiece. During operation, the riveting guide device 2 applies pressure to the workpiece along a specific direction of motion. The riveting guide device 2 and the carrier device 3 are arranged vertically. The riveting guide device 2 applies downward pressure and continues to apply pressure until it reaches the preset position to complete the riveting operation and firmly connect the workpiece. During the application of pressure by the riveting guide device 2, the carrier device 3 generates a buffering force along the direction of motion of the riveting guide device 2. The generation of this buffering force ensures that the instantaneous impact force applied by the riveting guide device 2 does not directly act entirely on the workpiece, but is gradually absorbed and reduced by the carrier device 3. Therefore, the carrier device 3 generates a buffering force when under pressure, which can effectively absorb the instantaneous impact force generated when the riveting guide device 2 applies pressure. This ensures that during the riveting process, the impact force is not directly transmitted to the workpiece, but is gradually reduced by the first buffer part 302 of the carrier device 3. This prevents the workpiece from cracking, deforming, or being damaged due to excessive impact force, thereby reducing the scrap rate and improving the product qualification rate. At the same time, it effectively reduces the peak impact force borne by the carrier device 3 itself during each riveting, reduces the rate of structural fatigue of the carrier device 3, and thus extends the service life of the entire riveting mechanism. In addition, the buffering force can suppress the vibration and displacement caused by the impact force, allowing the riveting cutter head to apply pressure to the workpiece more accurately, improving the positional accuracy and connection quality of the riveting.

[0043] Reference Figures 1-4 In one embodiment, the fixed bracket includes a base plate 10, a first support plate 11, and a support frame assembly. The first support plate 11 and the support frame assembly are respectively disposed on the base plate 10, and a specified interval is formed between the first support plate 11 and the support frame assembly. The carrier device 3 is disposed on the first support plate 11 and the support frame assembly, and the central axis of the carrier device 3 is located within the specified interval.

[0044] In the above embodiments, the fixed bracket includes a base plate 10, a first support plate 11, and a support frame assembly. The base plate 10 is the foundation of the entire fixed bracket, providing a stable mounting surface for the first support plate 11 and the support frame assembly. The first support plate 11 is vertically mounted on the base plate 10, forming a stable right-angle connection with the base plate 10. It works together with the support frame assembly to provide horizontal support for the carrier device 3. A specified interval is formed between it and the support frame assembly. This interval not only provides an accurate spatial position for the installation of the carrier device 3, but also plays an important role in handling special long rivets to be riveted, accommodating the end of the rivet that extends beyond the carrier device 3, ensuring that the workpiece does not fall during placement and riveting. The support frame assembly is mounted on the base plate 10 and works in conjunction with the first support plate 11 to form a stable frame structure to support the carrier device 3. The carrier device 3 is precisely positioned on the first support plate 11 and the support frame assembly, with its central axis strictly within the specified interval formed by the two. When encountering a long rivet workpiece, the carrier device 3 can be flexibly moved to the side of the first support plate 11 with the help of an external mechanism to provide sufficient space for placing the workpiece. Then it can be moved back to a suitable position for riveting operation, so that the entire fixed bracket can adapt to the riveting requirements of workpieces of different specifications, optimize the operation process, and improve the versatility and flexibility of the equipment.

[0045] Reference Figures 1-5 In one embodiment, the vehicle device 3 includes a first buffer pillar 30 and a buffer seat assembly 31. The first buffer pillar 30 is detachably connected to the first support plate 11 and the support frame assembly. The buffer seat assembly 31 is disposed on the buffer pillar. The buffer seat assembly 31 forms a specified distance with the first support plate 11 and the support frame assembly, respectively, and the top end of the buffer pillar forms a height difference with the top end of the buffer seat assembly 31.

[0046] In the above embodiments, the carrier device 3 includes a first buffer support column 30 and a buffer seat assembly 31. The first buffer support column 30 serves as a key support and a first buffer part 302 for the carrier device 3. One end of the first buffer support column 30 is detachably connected to the first support plate 11 and the support frame assembly, respectively, and the other end is used to withstand the pressure applied by the riveting guide device 2. The connection method is preferably a threaded connection. It passes through the buffer seat assembly 31, providing vertical support for the buffer seat assembly 31, and at the same time plays a buffering role during the riveting process, effectively dispersing and absorbing the impact force from the riveting guide device 2. The buffer seat assembly 31 is installed on the first buffer support column 30 and works in conjunction with the first buffer support column 30. The buffer seat assembly 31, together with the first support plate 11 and the support frame assembly, forms a specified distance. This distance provides the necessary space for the buffer seat assembly 31 to buffer its movement when subjected to pressure. The height difference between the top of the buffer support column and the top of the buffer seat assembly 31 is cleverly designed so that during the riveting process, the riveting guide device 2 first contacts the buffer seat assembly 31. By utilizing the buffering characteristics of the buffer seat assembly 31, the workpiece is protected from the impact of excessive instantaneous impact. Subsequently, as the pressure increases, the first buffer support column 30 further participates in the buffering process. Together, they ensure the gradual progression and effective performance of the buffering effect, thereby significantly reducing the impact force on the workpiece, reducing the risk of workpiece damage, and improving the product qualification rate.

[0047] Reference Figures 1-5 In one embodiment, the buffer seat assembly 31 includes a second support plate 310, a third support plate 311, and a second buffer support column 312. The second support plate 310 is fixedly connected to the first buffer support column 30. The third support plate 311 is connected to the first support plate 11 through the second buffer support column 312. The third support plate 311 is located at one end of the second support plate 310 near the riveting guide device 2, and the third support plate 311 is movably connected to the first buffer support column 30. When the third support plate 311 is subjected to the force of the riveting guide device 2, the third support plate 311 moves downwards for buffering through the second buffer support column 312.

[0048] In the above embodiment, the buffer seat assembly 31 includes a second support plate 310, a third support plate 311, and a second buffer support column 312. The second support plate 310 serves as the basic support structure of the buffer seat assembly 31, and is firmly fixed to the first buffer support column 30, providing a stable support foundation for the entire buffer seat assembly 31 and ensuring that other components can maintain a relatively stable positional relationship during operation. The third support plate 311 is located at the end of the second support plate 310 near the riveting guide device 2, and its top surface is higher than the top surface of the first buffer support column 30, so that when the riveting guide device 2 moves downward, it first contacts the third support plate 311. It is connected to the first support plate 11 through the second buffer support column 312 and is movably connected to the first buffer support column 30. This allows it to move relative to the first buffer support 30 when subjected to the force of the riveting guide device 2, thereby driving the second buffer support 312 to work. The second buffer support 312 consists of a support body 317 and a second buffer part 318. The support body 317 is fixed inside the second support plate 310, providing support and guidance for the second buffer part 318. The second buffer part 318 is slidably connected to the support body 317 and connected to the third support plate 311. When the third support plate 311 is subjected to pressure, it can drive the second buffer part 318 to slide downward inside the support body 317, realizing buffering movement, effectively reducing impact force, protecting workpieces and equipment, thereby reducing the risk of workpiece damage, improving product qualification rate, and extending equipment service life.

[0049] Reference Figures 1-5 In one embodiment, the first buffer support column 30 includes a fixing part 301 and a first buffer part 302. The fixing part 301 passes through the second support plate 310 and is disposed on the first support plate 11 and the support frame assembly. The first buffer part 302 is slidably connected to the end of the fixing part 301 away from the second support plate 310, and the first buffer part 302 passes through the third support plate 311. A limiting piece 303 is provided at the end of the first buffer part 302 near the pressing guide device 2. The limiting piece 303 is in contact with the third support plate 311.

[0050] In the above embodiment, the first buffer support column 30 includes a fixing part 301 and a first buffer part 302. The fixing part 301 penetrates the second support plate 310 and is installed on the first support plate 11 and the support frame assembly, providing a stable support foundation for the entire first buffer support column 30, ensuring that its position remains fixed during the riveting process, bearing the pressure from above and transmitting it to the structure below. The first buffer part 302 is slidably connected to the end of the fixing part 301 away from the second support plate 310 and penetrates the third support plate 311. A limiting piece 303 is provided at the end near the riveting guide device 2, and the diameter of the limiting piece 303 is larger than the diameter of the through hole penetrated by the first buffer part 302, so that the limiting piece 303 contacts the third support plate 311, thereby restricting the top of the third support plate 311 through the limiting piece 303, preventing it from sliding off the first buffer part 302. In the initial riveting stage, the third support plate 311 first provides independent buffering. When the riveting guide device 2 makes the top surface of the third support plate 311 flush with the top surface of the first buffer support column 30 (i.e., the limiting piece 303 is flush with the top surface of the third support plate 311), the third support plate 311 and the first buffer part 302 move synchronously. The first buffer part 302 slides downward within the fixed part 301 for buffering. The buffering length of the second buffer support column 312 is greater than that of the first buffer support column 30. The two work together to form a graded buffering. The second buffer support column 312 is the main buffer first. When a certain level is reached, the first buffer part 302 of the first buffer support column 30 further buffers and continues riveting. After the buffering is in place, the riveting is completed. The graded buffering mechanism can better adapt to the changes in impact force during the riveting process, effectively reduce the peak impact force on the workpiece, reduce the risk of damage, and improve the product qualification rate.

[0051] Reference Figures 1-6 In one embodiment, the third support plate 311 is provided with a receiving groove 313, and the buffer seat assembly 31 further includes a fourth support plate 314. The fourth support plate 314 is detachably connected to the receiving groove 313, and one end of the fourth support plate 314 near the limiting piece 303 contacts the limiting piece 303, and the top end of the fourth support plate 314 is located on the same plane as the top end of the third support plate 311.

[0052] In the above embodiments, the buffer seat assembly 31 further includes a fourth support plate 314. A receiving groove 313 is provided on the third support plate 311, providing installation space for the fourth support plate 314. The shape and size of the receiving groove 313 match the fourth support plate 314, ensuring that the fourth support plate 314 can be accurately installed and stably positioned therein. The fourth support plate 314 is detachably connected to the receiving groove 313 of the third support plate 311. Its end near the limiting piece 303 is in close contact with the limiting piece 303, and its top end is on the same plane as the top end of the third support plate 311, so that when the riveting guide device 2 continues to move downward, it can simultaneously... Contact with the third support plate 311 and the fourth support plate 314 enables the transmission of force. The fourth support plate 314, together with the first buffer pillar 30 and the third support plate 311, forms a collaborative system. When subjected to the pressure of the riveting guide device 2, the fourth support plate 314, through contact with the limiting piece 303, drives the first buffer part 302 of the first buffer pillar 30 and the third support plate 311 to move downward synchronously, further enhancing the buffering effect. This ensures that the entire carrier device 3 can stably disperse and buffer the force of the riveting guide device 2, protecting the workpiece to be riveted from excessive impact, while also ensuring the smoothness and accuracy of the riveting process.

[0053] Reference Figures 1-6 In one embodiment, the riveting mechanism further includes a detection device 4. One end of the third support plate 311 is provided with an extension plate 315, and the extension plate 315 is provided with a through hole 316. The detection device 4 is disposed on the support frame assembly and is arranged correspondingly to the first buffer support column 30. The detection device 4 is used to collect the buffer trajectory of the first buffer support column 30 and the buffer seat assembly 31, and to collect the movement trajectory of the riveting guide device 2 through the through hole 316.

[0054] In the above embodiment, the riveting mechanism also includes a detection device 4. The detection device 4 is an important detection component in the riveting mechanism, used to acquire key data in the riveting process in real time. The detection device 4 is preferably a displacement sensor or a laser rangefinder. An extension plate 315 provided at one end of the third support plate 311 provides a detection point for the detection device 4. A through hole 316 on the extension plate 315 provides a channel for detecting the movement trajectory of the riveting guide device 2. The extension plate 315 and the third support plate 311 are integrally formed to ensure their stability. The position and size of the through hole 316 are precisely designed so that the detection device 4 can accurately collect relevant information. The detection device 4 is installed... On the support frame assembly, corresponding to the first buffer support column 30, during the riveting process, the detection device 4 collects the buffer trajectory data of the first buffer support column 30 and the buffer seat assembly 31 in real time, as well as the motion trajectory data of the riveting guide device 2 through the through hole 316. The operator observes the detection data, which allows the operator to intuitively understand the dynamic changes of each component during the riveting process and judge whether the riveting process is normal. If an abnormality is found, the riveting parameters are adjusted according to the data. After the riveting is completed, the detection data is analyzed, the experience is summarized, and a reference is provided for the next riveting. The detection device 4 is calibrated and maintained regularly to ensure its detection accuracy and ensure stable riveting quality.

[0055] Reference Figures 1-5 In one embodiment, the support frame assembly includes an end plate 120, a fifth support plate 121, and at least two side plates 122. The side plates 122 and the end plate 120 are disposed on the base plate 10, and one end of the side plate 122 away from the first support plate 11 is connected to the end plate 120. The side plate 122 is provided with a support platform 123 recessed toward the end plate 120. The fifth support plate 121 is disposed on the support platform 123 for supporting the carrier device 3.

[0056] In the above embodiment, the support frame assembly includes an end plate 120, a fifth support plate 121, and at least two side plates 122. The side plates 122 and the end plate 120 are disposed on the base plate 10. The end of the side plate 122 away from the first support plate 11 is connected to the end plate 120, together forming the frame boundary of the support frame assembly, which plays a role in positioning and strengthening structural stability, ensuring that the entire support frame will not deform or shift when subjected to pressure. A support platform 123 recessed towards the end plate 120 is provided on the side plate 122, and the fifth support plate 121 is disposed on the support platform 123. The support platform 123 is preferably U-shaped, with one side longer than the other, and the shorter side is used to place the fifth support plate 121. 1. Its main function is to support the carrier device 3; the fifth support plate 121 and the second support plate 310 form a specified distance, which provides the necessary space for the movement of the carrier device 3 during the buffering process, ensuring the smooth progress of the buffering action. At the same time, the detection device 4 is set on the fifth support plate 121 to facilitate the monitoring of the riveting process. The fifth support plate 121 and the first support plate 11 form a specified interval, and the carrier device 3 is located at the center of this interval, ensuring the balance and stability of the carrier device 3 in the horizontal direction, so that the carrier device 3 is subjected to uniform force during the riveting process, reducing problems such as poor buffering effect or workpiece displacement caused by uneven force, reducing equipment shaking, and extending the service life of the equipment.

[0057] Reference Figures 1-3 In one embodiment, the support frame assembly further includes a top plate 124, and the pressing and guiding device 2 includes a booster cylinder 20 and a guide rod 21. The top plate 124 is disposed at the end of the side plate 122 away from the bottom plate 10, and the top plate 124, the end plate 120, and the side plate 122 together form a placement groove 125. The booster cylinder 20 and the guide rod 21 are spaced apart in the placement groove 125 along the length direction of the placement groove 125, and the end of the booster cylinder 20 and the guide rod 21 that passes through the top plate 124 are connected by a connecting plate 22, so that the guide rod 21 moves synchronously with the output shaft of the booster cylinder 20 through the connecting plate 22.

[0058] In the above embodiment, the support frame assembly also includes a top plate 124. The top plate 124, as part of the support frame assembly, is installed at the end of the side plate 122 away from the bottom plate 10, forming a placement groove 125 together with the side plate 122 and the end plate 120. The top plate 124 provides a mounting base for the pressure cylinder 20 and the guide rod 21, and also protects the components within the placement groove 125, preventing external factors from interfering with the normal operation of the riveting guide device 2. The riveting guide device 2 includes a pressure cylinder 20 and a guide rod 21. The pressure cylinder 20 is the power source of the riveting guide device 2, generating a linear driving force through internal pressure changes to push the connecting plate 22 downwards, thereby providing sufficient pressure for the riveting process. It and the guide rod 21 are spaced apart along the length of the placement groove 125, reasonably distributed within the placement groove 125, ensuring sufficient force. The pressure is applied evenly; the end of the pressure cylinder 20 and the guide rod 21 that passes through the top plate 124 is connected by the connecting plate 22, so that the two can move synchronously. That is, the extension and retraction of the output shaft of the pressure cylinder 20 can be accurately transmitted to the guide rod 21 through the connecting plate 22. During the riveting operation, the power generated by the pressure cylinder 20 is transmitted through the connecting plate 22, which drives the guide rod 21 to move synchronously, so that the riveting head assembly accurately applies pressure to the workpiece placed on the carrier device 3 to complete the riveting operation. The guide rod 21 works in coordination with the pressure cylinder 20. Its main function is to provide accurate guidance for the movement of the connecting plate 22, so that when the pressure cylinder 20 is working, the connecting plate 22 can move up and down stably in the vertical direction, preventing it from deviating or shaking during the movement, thereby ensuring that the riveting force is accurately transmitted to the workpiece to be riveted.

[0059] Reference Figures 1-3 In one embodiment, the riveting guide device 2 further includes a pressing cutter head assembly 23, which includes a connecting block 230 and a cutter head body 231. The connecting block 230 is detachably connected to the end of the connecting plate 22 away from the pressure cylinder 20, and the cutter head body 231 is disposed at the end of the connecting block 230 away from the connecting plate 22. The centers of the cutter head body 231, the connecting block 230, the pressure cylinder 20, and the carrier device 3 are located on the same axis.

[0060] In the above embodiments, the riveting guide device 2 further includes a lowering cutter head assembly 23. The lowering cutter head assembly 23 includes a connecting block 230 and a cutter head body 231. The connecting block 230 serves as an intermediate connector and is detachably connected to the end of the connecting plate 22 away from the booster cylinder 20. Its detachable nature facilitates the replacement and maintenance of the cutter head body 231 to adapt to different types of riveting operations. The connecting block 230 transmits the power of the booster cylinder 20, stably transferring the force from the connecting plate 22 to the cutter head body 231. The cutter head body 231 is located at the end of the connecting block 230 away from the connecting plate 22 and is the component that directly contacts the workpiece to be riveted and completes the riveting operation. The shape, material, and size of the cutter head body 231 are determined according to the specific riveting operation. The process design ensures accurate riveting of the workpiece, achieving the desired connection effect through rivet deformation. During riveting, the pressure cylinder 20 pushes the connecting plate 22, which in turn moves the connecting block 230. The connecting block 230 then transmits force to the cutter head body 231, causing the cutter head body 231 to rivet the workpiece. The centers of the cutter head body 231, connecting block 230, pressure cylinder 20, and carrier device 3 are all on the same axis. This ensures that the pressure generated by the pressure cylinder 20 is accurately transmitted to the cutter head body 231 along the axial direction during riveting, and then acts on the workpiece on the carrier device 3. This avoids problems such as uneven riveting, workpiece damage, or poor riveting quality caused by force deviation, greatly improving riveting accuracy.
