[0021] When the workpiece is installed on the jig 11, the air cylinder 3 is started to drive the floating plate 51 to move downward, and at this time, the floating plate 51 drives the pressing block 53 to move downward synchronously, so that the pressing block 53 drives the bottom of the extrusion block 54 in the installation groove to contact the workpiece. When the bottom of the extrusion block 54 contacts the workpiece, the floating plate 51 continues to drive the pressing block 53 to move downward, and at this time, the downward movement of the extrusion block 54 is blocked, so that the five extrusion blocks 54 respectively slide along the inclined surfaces of the installation groove and the inclined surfaces of the core block 52 until they completely enter the installation groove of the pressing block 53. In this process, the inclined surfaces of the extrusion block 54 are slidably connected with the inclined surfaces of the installation groove and the core block 52, so that the pressing mechanism 5 can press the rivets on the side wall of the workpiece, and the problem of low riveting efficiency caused by the fact that the riveting structure cannot complete the riveting work at one time is solved.
[0022] Referring to Figure 3 , Figure 4 and Figure 5 , the two inclined surfaces of the core block 52 are symmetrically provided with downward inclined first inclined sliding grooves 521; the three inclined surfaces of the installation groove are provided with downward inclined second inclined sliding grooves 533; and the inclined surface of the extrusion block 54 is provided with upward inclined first guide sliding blocks 541, which are slidably connected with the corresponding second inclined sliding grooves 533 and first inclined sliding grooves 521, respectively.

[0027] To ensure the stability of the side sliding block 62, the second guide sliding block 621 is arranged on the inclined surface of one side of the side sliding block 62. When the bottom of the side sliding block 62 contacts the workpiece, the descending of the side sliding block 62 is blocked, at this time, the side sliding block 62 will slide on the inclined surface of one side and the inclined surface of one side of the limiting seat 611. In this process, the second guide sliding block 621 on the inclined surface of the side sliding block 62 will slide in the third inclined sliding groove 612, and the second guide sliding block 621 cooperates with the third inclined sliding groove 612 to ensure the stability of the side sliding block 62.
