Detailed Description

Fig. 1 reflects a specific structure of the present invention. It can be seen from the figure that the present invention has a riveting machine 1, a carrier mechanism 2, a base 3, wherein the riveting machine 1 is commercially available. The riveting machine 1 and the bracket mechanism 2 are respectively arranged at two ends of the base 3, the base 3 is provided with a guide rail 31, a screw rod mechanism 32 and a screw rod motor 33, the screw rod motor 33 drives the screw rod mechanism to move, a nut of the screw rod mechanism 32 is arranged at the bottom of the riveting machine 1, and the riveting machine 1 is driven by the screw rod mechanism 32 to horizontally move, so that a riveting head can quickly and accurately reach the position of a workpiece.

Fig. 1 further shows that the bracket mechanism 2 is installed at the other end of the base 3, the bracket mechanism 2 includes an upright post 21, a lifting motor 22, and a tray 23, the tray 23 has a supporting bracket 231 and a telescopic arm 232, wherein the lifting motor 22 drives the upright post 21 to lift, so as to realize height matching between workpieces of different specifications and the riveting machine. The telescopic arm 232 is installed in the support bracket 231 and can slide and stretch according to the specification of a workpiece, and a locking hand wheel 235 is arranged on the support bracket 231. On the telescopic arm 232, a workpiece support roller 233 is mounted, on both sides of which are clamping rollers 234, the shape of the space left between the support roller 25 and the two clamping rollers 234 matching the shape of the skin, so that the clamping rollers 234 also serve here as guides for the placement of the skin workpiece. The telescopic arm 232 slides to a proper position, the skin A is placed on the supporting roller 233 until the skin A is completely seated on the supporting roller 233, then the telescopic arm 232 is locked by the locking hand wheel 235 to be positioned, the clamping roller 234 is clamped by a wrench to clamp the skin A, and then scribing can be started.
