6. The clinching apparatus of claim 1, further including a slider (52), the slider (52) being slidably disposed on the base (10) along a first direction, the ram assembly (30) and the rivet assembly (40) being disposed side-by-side on the slider (52) along the first direction;

The press system (11) and the fixing assembly (20) are arranged at intervals along a second direction, and the pressing head assembly (30) and the rivet head assembly (40) are both in sliding connection with the sliding piece (52) along the second direction.

7. The press riveting apparatus according to claim 6, wherein the press system (11) is provided with a socket end, and the slider (52) drives the ram assembly (30) and the rivet assembly (40) to move in the first direction so that the socket end can be slidably inserted into the ram assembly (30) or the rivet assembly (40).

8. The clinching apparatus of claim 6, wherein the base (10) is provided with a first rail (12) extending in the first direction, the slider (52) being slidably engaged with the base (10) by the first rail (12), the first rail (12) being provided with at least two side-by-side in the second direction.

9. The clinching apparatus of claim 6, further comprising a driver (51) provided on the base (10), the driver (51) for driving the slider (52) to slide in the first direction.

10. The clinching apparatus of any one of claims 1 to 9, further including a first displacement sensor (61) connected to the ram assembly (30) for detecting a primary press-fit distance;

And/or further comprising a second displacement sensor (62) coupled to the rivet assembly (40) for detecting a back pressure distance.
