The downward power output by the riveting cylinder drives the riveting mechanism connected thereto downward through the transmission assembly to approach the relay assembly on the riveting platform, thereby realizing automatic riveting.

[0017] The special thing is that the riveting platform of the present invention not only realizes the carrying of relay components, but also has the adaptive flexible clamping and fixing positioning function in the horizontal plane and flexible bearing support in the vertical direction; specifically, the riveting platform includes a flexible support component, a platform seat, a pushing component and a positioning component. The flexible support component uses a horizontally arranged support as a bearing structure, and a connecting plate and a base are provided under the support. The three are connected and fixed to form an integral structure. A plurality of guide columns are slidably inserted on the support, and the top end of the guide column is horizontally connected to the bearing seat. The bearing seat is relatively free to move in the vertical direction relative to the support, and is guided and limited by a plurality of guide columns; a plurality of pillars are also vertically provided at the bottom of the bearing seat, and the pillars extend downward and are slidably inserted on the support. Inside the seat, two groups of support springs are provided on the pillars, of which the upper support spring is located between the bearing seat and the support, and the lower support spring is located between the connecting plate and the base, forming a bipolar flexible spring bearing support structure; during the riveting process, when the bearing seat is subjected to downward pressure, the bearing seat drives the pillar to move downward through the support, the upper support spring is compressed, and the lower support spring is released, and the upper support spring provides elastic buffering for the bearing seat, so that the bearing seat can flexibly support the relay assembly during the riveting process; when the riveting is completed, when the downward pressure on the bearing seat disappears, the compressed support spring generates an upward elastic force to reset the bearing seat upward, and at the same time the lower support spring is compressed, so that the bearing seat can flexibly reset. Furthermore, a platform seat is horizontally provided above the bearing seat, and the platform seat is used to carry and place the relay assembly. A plurality of upper push columns are provided on the bearing seat in parallel and spaced corresponding to the connecting columns of the relay assembly. The plurality of push columns pass through the platform seat upward and are used to push correspondingly from below under the connecting columns of the relay assembly, so as to locally support the connecting columns from below during the riveting process, thereby ensuring uniform force during the riveting process; during the riveting process, the elastic force of the support spring not only makes the bearing seat elastically buffered, but also drives the bearing seat to drive the upper push column to maintain a state of continuously pushing the connecting column upward, thereby ensuring that the upper push column maintains a state of continuously supporting the connecting column, thereby ensuring its support stability; in addition, an upper push block is also provided under the bearing seat of the present invention, which passes downward through the support, connecting plate and base, and extends under the base. During the riveting process, power can be output to the upper push block through an external power mechanism to drive the upper push block to drive the bearing seat and the upper push column thereon to move upward, thereby completing targeted support and pushing of the connecting column. Furthermore, the platform seat of the present invention is provided with a U-shaped support block, and an inwardly recessed bearing groove is provided in the support block. One end of the bearing groove extends to the opening of the support block, and an inwardly recessed rivet groove is provided on the inner wall of the support block at the other end of the bearing groove. The relay terminal to be riveted is placed in the rivet groove, and one end of the relay terminal is inserted into the connecting column and supported by the rivet groove.

After the riveting is completed, the support block is pushed close to the platform seat by an external power mechanism, so that the positioning seat drives the positioning block away from the bearing groove to facilitate the removal of the relay terminal.

[0018] The cam is provided with a plurality of guide wheels, and the guide wheels are provided with a plurality of guide wheels, and the guide wheels are provided with a plurality of guide wheels, and the guide wheels are provided with a plurality of guide wheels. The guide wheels are provided with a plurality of guide wheels, and the guide wheels are provided with a plurality of guide wheels.

[0019] Furthermore, based on the process requirement of riveting and connecting the relay terminal and the relay spring piece through multiple connecting columns, the riveting mechanism of the present invention uses multiple riveting rods arranged in parallel and at intervals as riveting actuators, and the multiple riveting rods are respectively arranged corresponding to the multiple connecting columns in the vertical direction, and the multiple riveting rods are respectively inserted into the pre-stressing sleeve and slide freely in the pre-stressing sleeve; the pre-stressing sleeve is inserted into the riveting slide groove of the sleeve, and inner support blocks are respectively provided horizontally on both sides of the inner side of the riveting slide groove, and protruding parts extending horizontally outward are respectively provided on both sides of the top of the pre-stressing sleeve, and the two protruding parts are respectively placed on the two inner support blocks and supported by the inner support blocks; at the same time, riveting springs are respectively provided above the two protruding parts, and the upper ends of the riveting springs push against the riveting connection seat above, and the lower ends of the riveting springs push against the protruding parts on both sides of the pre-stressing sleeve; When the riveting mechanism descends as a whole, the bottom of the pre-stressing sleeve first contacts the surface of the relay terminal. As the riveting mechanism continues to descend, the pre-stressing sleeve, after receiving the upward reaction force from the surface of the relay terminal, extends upward into the sleeve and compresses the riveting spring upward until the riveting rod gradually extends from the bottom of the pre-stressing sleeve and contacts the top surface of the connecting column. As it continues to descend, the riveting rod squeezes the connecting column downward to deform the material of the connecting column and rivet the relay terminal and the relay spring together. Through the flexible setting of the pre-stressing sleeve, the pre-stressing and fixing of the relay terminal surface before riveting is achieved to ensure its position stability during the riveting process. At the same time, the riveting rod is set in the pre-stressing sleeve to assist the riveting rod in riveting, avoiding bending or breaking due to excessive force during the riveting process, ensuring the riveting accuracy and improving the riveting life. Furthermore, the side of the sleeve of the present invention is also provided with a side pressure block, which extends downward to the side of the pre-pressing sleeve so as to press the relay terminal downward as the sleeve descends, thereby avoiding position displacement of the relay terminal during the riveting process and ensuring the accuracy of the riveting position.
