A fixed plate 79 is fixedly installed on the outer side of the sliding column 77, and a roller 710 is rotatably installed on the outer side of the fixed plate 79, so that the gear 74 drives the two-way threaded rod 73 to rotate, so that the threaded blocks 75 on both sides move toward each other, and the threaded blocks 75 drive the clamping plates 76 to approach each other, so that the sliding columns 77 on both sides move toward each other under the restriction of the long groove 78, so that the fixed plate 79 drives the roller 710 to fit the workbench 3 to move, and then the clamping plates 76 move toward each other more smoothly, and then the clamping plates 76 clamp the workpiece body 5 in the appropriate position, and an L-shaped plate 711 is fixedly installed on the outer side of the clamping plate 76, and a straightening funnel 712 is fixedly installed on the outer side of the L-shaped plate 711. There are multiple sets of threaded blocks 75, clamping plates 76, sliding columns 77, fixing plates 79, rollers 710, L-shaped plates 711 and alignment funnels 712, and the multiple sets of threaded blocks 75, clamping plates 76, sliding columns 77, fixing plates 79, rollers 710, L-shaped plates 711 and alignment funnels 712 are mirrored with the vertical center line of the long slot 78 in the front-rear direction as the mirror axis, and are mirrored at the left and right ends of the long slot 78. The alignment funnel 712 is coaxial with the center of the circular cross section of the workpiece body 5, and the L-shaped plate 711 drives the alignment funnel 712 to the top of the circular hole of the workpiece, so that the rivet nut 67 can better align the workpiece hole when it falls, so as to better clamp the workpiece body 5 and accurately locate the workpiece hole, so that the rivet nut 67 can better locate the workpiece hole, thereby improving the riveting quality.

Since the placement mechanism is an existing device of the prior art, it will not be described here), so that the rivet nut 67 falls into the workpiece hole, so that the servo telescopic rod 61 drives the servo drill 62 to approach, so that the servo drill 62 drives the rivet drill bit 63 to approach the workpiece body 5, so that the servo drill 62 drives the rivet drill bit 63 to the threaded hole 673, and then the rivet drill bit 63 is pulled up and rotated so that the extrusion section 672 moves upward to approach the circular The shaped clamp ring 671 is used to pull the rivet, reducing the influence of human factors on the riveting quality, and then quickly and continuously riveting, shortening the production cycle. Because the workpiece body 5 is easy to shift during transportation, and there is a risk of inaccurate clamping when the rivet nut 67 falls, the servo hydraulic cylinder 71 is turned on, so that the piston end of the servo hydraulic cylinder 71 drives the rack 72 to push outward, so that the gear 74 drives the bidirectional threaded rod 73 to rotate, so that the threaded blocks 75 on both sides move toward each other, so that the threaded blocks 75 drive the clamping plates 76 to move toward each other, so that the sliding on both sides The columns 77 move toward each other under the restriction of the long groove 78, so that the fixed plate 79 drives the roller 710 to move in contact with the workbench 3, and then the clamping plate 76 moves toward each other more smoothly, and then the clamping plate 76 clamps the workpiece body 5 in the appropriate position. At the same time, the L-shaped plate 711 drives the straightening funnel 712 to above the circular hole of the workpiece, so that the rivet nut 67 can better clamp the workpiece hole when falling, thereby better clamping the workpiece body 5 and accurately positioning the workpiece hole, and then the rivet nut 67 can better position the workpiece hole, thereby improving the riveting quality.
