[0029] Specifically, when the assembly table for riveting and assembling aerospace structural parts is in operation / use: Place the parts to be processed on the tooling table 21.

By extending the telescopic push rod 233, the auxiliary rod 232 is pushed to drive the positioning clamp 234 to flip relative to the tooling table 21 to clamp and fix the workpiece, achieving the purpose of effectively fixing the parts. When performing riveting operations, the riveting component can be driven to move by the X-axis lead screw module 12 and the Y-axis lead screw module 13, so that the riveting component 30 performs riveting operations at the processing position. Specifically, the first motor 43 can drive the worm 45 to engage and rotate the worm gear 46. The worm gear 46 drives the hollow shaft 41 to drive the second cam 48 to rotate. The second cam 48 and the second push rod 410 are in contact and cooperate to push the horizontal slide bar 35 to slide horizontally. Thus, the sleeve 37 is rotated by pulling through three connecting rods. When the sleeve 37 rotates, since the lifting nail driving shaft 38 is rotationally restricted, the lifting nail driving shaft 38 is driven to slide up and down on the rivet supply table 391, so as to push the rivets to the riveting position. At the same time, the positioning bolt 414 can be opened to adjust the position of the third connecting rod 413, and the rotation angle of the sleeve 37 is adjusted to adjust the length of the lifting nail driving shaft 38 extending out to suit different riveting actions of the rivets. After losing the extrusion force of the cam, the horizontal slide bar 35 and the lifting slide bar 33 can be pulled back to their original positions by the first spring 310 and the second spring 311 respectively. The first cam 47 and the first push rod 49 cooperate to push the lifting slide bar 33 to slide up and down, so as to adjust the position of the rivet sleeve 393. At the same time, the rivets slide through the rivet supply pipe 392 into the rivet sleeve 393 for storage. When driving the nails, the rivet sleeve 393 is expanded. After driving the nails, the rivet sleeve 393 closes by its own magnetic adsorption force.
