For further ease of understanding, fig. 1 illustrates a schematic view of the riveting jig cooperating with the rivet 33 and the rivet 32.

The horizontal position of the jig platform 24 can be adjusted by the lateral movement component, so that rivets 32 at different horizontal positions on the jig platform 24 (generally, rivets 32 at different heights have different horizontal positions) can be aligned with the rivet head 411 of the riveting machine 41; the height of the jig platform 24 can be adjusted by the jig lifting assembly, so that the rivets 32 with different heights on the jig platform 24 can meet the height requirement of the riveting machine 41 during riveting. Namely, the continuous riveting operation can be carried out on the rivets 32 with different heights through the matching of the components, and the production efficiency is improved. In addition, because the tool platform 24 is lifted or lowered by the mutually matched stepped surfaces, in the whole riveting process, the tool platform 24 is always connected with the final supporting platform (the riveting machine platform 412) by the supporting piece, namely the tool platform 24, the second sliding block 23 and the fixing plate 21 can be regarded as a stressed whole, the effect is equal to that the tool platform 24 is fixed on the final supporting platform (the riveting machine platform 412), and the structure is stable and the stress is large.

After the riveting is completed, the second slider 23 will be retracted under the driving of the driver 22, taking fig. 3 as an example, the second slider 23 moves leftwards, and at this time, the jig platform 24 needs to descend along the vertical guide 25 for the next riveting, so that the jig platform 24 falls back to the original position by the external force besides the self gravity through the downward elastic force provided by the elastic member, thereby ensuring the reliability of the resetting of the jig platform 24.

Preferably, the elastic member is a spring (not shown), the fixing plate 21 is provided with a mounting bracket 27, and the spring is disposed between the top end of the mounting bracket 27 and the jig platform 24. I.e. the downward spring force provided by the resilient member is provided in particular by a spring. Specifically, a spring mounting post or a spring mounting hole may be further disposed at the spring connection position of the mounting bracket 27 and the jig platform 24 to ensure the reliability of the spring connection.

Further, when the first step surface 131 and the second step surface 241 slide with each other, at least one second level abuts against the first horizontal surface 1311.

The working process of the invention is as follows:

after the riveting member 33 and the rivet 32 are assembled, the assembly is placed on a riveting jig, and the rivet A (the rivet needing the first riveting) on the riveting member 33 is moved to the position below the riveting head of the riveting machine 41 by the transverse moving assembly to start riveting;

after the rivet A is riveted, the rivet B (a rivet needing second riveting) is continuously moved to the position below a riveting head of the riveting machine 41 through the transverse moving assembly, and then the jig platform 24 is lifted through the jig lifting assembly (the height of the jig platform 24 is equal to the height difference between the rivet A and the rivet B), so that the rivet B can reach the riveting height of the riveting machine 41;

and so on until the riveting of the rivets 32 with different heights on the riveting piece 33 is completed;

after riveting, the driver 22 drives the second slider 23 to return, the jig platform 24 falls back to the initial position under the action of the self-weight and the return spring, resetting is completed, and the riveted part 33 is taken out at the same time.
