[0039] Reference Figure 1-Figure 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 arranged on the fixed bracket, and the carrier device 3 is used to carry the workpiece to be riveted;

[0041] The riveting guide device 2 is arranged on the fixed bracket, and the riveting guide device 2 is arranged 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 embodiment, the riveting mechanism includes a fixed bracket, a riveting guide device 2 and a carrier device 3. The fixed bracket serves as the basic supporting structure of the entire riveting mechanism, and provides a stable installation position for the riveting guide device 2 and the carrier device 3, ensuring that the components will not be displaced or shaken 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 relatively arranged on the fixed bracket, and the carrier device 3 is used to carry the workpiece to be riveted and provide a stable placement platform for the workpiece. The main function of the riveting guide device 2 is to provide accurate riveting force and apply the force to the workpiece to be riveted. On the riveted workpiece, when working, it applies pressure to the workpiece along a specific movement extension direction, wherein the riveting guide device 2 and the carrier device 3 are arranged up and down, and the riveting guide device 2 applies pressure downward, and the riveting guide device 2 continues to apply pressure until it reaches the preset position to complete the riveting operation and firmly connect the workpiece. During the pressure application process of the riveting guide device 2, the carrier device 3 generates a buffering force along the movement direction 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 will not directly act on the workpiece, but will be gradually absorbed and reduced by the carrier device 3. Therefore, the carrier device 3 generates a buffering force when it is under pressure, which can effectively absorb the instantaneous impact force generated by the riveting guide device 2 when applying pressure, so that during the riveting process, the impact force will not be directly transmitted to the workpiece in full, but will be gradually reduced by the first buffer part 302 of the carrier device 3, thereby avoiding the workpiece from cracking, deformation or other damage due to excessive impact force, thereby reducing the scrap rate and improving the product qualification rate. At the same time, it effectively reduces the impact force peak value 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. At the same time, the buffering force can suppress the vibration and displacement caused by the impact force, so that the riveting tool head can apply pressure to the workpiece more accurately, thereby improving the position accuracy and connection quality of the riveting.

[0044] In the above embodiment, the fixed bracket includes a base plate 10, a first support plate 11 and a support frame assembly. The base plate 10 is the basic part of the entire fixed bracket, and provides a stable installation plane for the first support plate 11 and the support frame assembly; the first support plate 11 is vertically installed on the base plate 10, forming a stable right-angle connection with the base plate 10, and it cooperates with the support frame assembly to provide horizontal support for the carrier device 3, and 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 processing special long rivet workpieces to be riveted, and can accommodate one end of the rivet that exceeds the carrier device 3 to ensure that the workpiece will not be placed and riveted during the riveting process. Obstructed; the support frame assembly is installed as a whole on the base plate 10, and cooperates with the first support plate 11 to jointly construct a stable frame structure to carry the carrier device 3; the carrier device 3 is precisely arranged on the first support plate 11 and the support frame assembly, and its central axis is strictly located within the specified interval formed by the two. When encountering a long rivet workpiece, with the help of an external mechanism, the carrier device 3 can be flexibly moved to the side of the first support plate 11 on the first support plate 11 and the support frame assembly to provide sufficient space for placing the workpiece, and then moved back to a suitable position for riveting operations, 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.

The first buffer pillar 30 serves as a key support of the carrier device 3 and a first buffer part 302. One end of the first buffer pillar 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, the same below. It penetrates the buffer seat assembly 31 to provide vertical support force for the buffer seat assembly 31, and at the same time plays a buffering role in 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 pillar 30 and cooperates with the first buffer pillar 30 Working, it forms a specified distance with the first support plate 11 and the support frame assembly respectively, and this distance provides necessary space for the buffering movement of the buffer seat assembly 31 when it is subjected to pressure. The height difference between the top of the buffer pillar 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 with the buffer seat assembly 31, and uses the buffering characteristics of the buffer seat assembly 31 to protect the workpiece from the influence of instantaneous excessive impact force. Then, as the pressure increases, the first buffer pillar 30 further participates in the buffering process. The two together ensure the gradual progression and effective use of the buffering effect, thereby greatly reducing the impact force on the workpiece, reducing the risk of workpiece damage, and improving the product qualification rate.

[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 pillar 312. The second support plate 310 serves as the basic support structure of the buffer seat assembly 31 and is firmly fixedly connected to the first buffer pillar 30, providing a stable support foundation for the entire buffer seat assembly 31, ensuring that other components can maintain a relatively stable positional relationship during operation; the third support plate 311 is located at one end of the second support plate 310 close to the rivet guide device 2, and its top surface is higher than the top surface of the first buffer pillar 30, so that the rivet guide device 2 first contacts the third support plate 311 when it moves downward, and it is connected to the first support plate 11 through the second buffer pillar 312, and is movably connected to the first buffer pillar 30 , so that it can move relative to the first buffer support 30 when it is subjected to the force of the riveting guide device 2, thereby driving the second buffer support 312 to work; the second buffer support 312 is composed of a support body 317 and a second buffer portion 318, the support body 317 is fixed in the second support plate 310, and provides support and guidance for the second buffer portion 318, the second buffer portion 318 is slidably connected to the support body 317, and is connected to the third support plate 311. When the third support plate 311 is subjected to pressure, it can drive the second buffer portion 318 to slide downward in the support body 317, realize buffering movement, effectively reduce impact force, protect workpieces and equipment, and thereby reduce the risk of workpiece damage, improve product qualification rate, and extend equipment service life.

[0050] In the above embodiment, the first buffer pillar 30 includes a fixing portion 301 and a first buffer portion 302. The fixing portion 301 passes through 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 pillar 30, ensuring that its position remains fixed during the riveting process, and withstands the pressure from above and transmits it to the lower structure; the first buffer portion 302 is slidably connected to the end of the fixing portion 301 away from the second support plate 310, and passes through the third support plate 311, and a limiting piece 303 is provided at one end thereof close to the riveting guide device 2, and the diameter of the limiting piece 303 is larger than the diameter of the through hole passed by the first buffer portion 302, so that the limiting piece 303 contacts the third support plate 311, and then the top of the third support plate 311 is limited by the limiting piece 303, so that it will not slide from the first buffer portion 302 It can be seen that in the initial riveting stage, the third support plate 311 is first buffered separately. 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 pillar 30 (that is, the limit plate 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, and the first buffer part 302 slides downward in the fixing part 301 for buffering. The buffering length of the second buffer pillar 312 is greater than that of the first buffer pillar 30. The two work together to form a graded buffer. The second buffer pillar 312 is mainly used for buffering. When it reaches a certain level, the first buffer part 302 of the first buffer pillar 30 further buffers and continues to rivet. After 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.
