[0018] Beneficial effects:

[0019] When riveting, start the hydraulic push rod to drive the punch down to achieve the riveting effect. Multiple punches have different specifications and are suitable for riveting nuts of different specifications. Rotate the second disc to adjust the position of the punch, which is convenient for riveting different nuts.

The position of the placement port can be adjusted by rotating the turntable, and the positioning column 2 is used to position it inside the positioning hole 2 to position the turntable so that the turntable can rotate with the shaft column;

[0022] When the hydraulic push rod pushes the disc 1 and disc 2 to descend, the disc 2 will first squeeze the pressure block through the inclined surface to shrink toward the inside of the inflatable box 2, and exhaust into the inside of the inflatable box 1, so that the tray rises, and the sunroof guide rail of the car rises. At the same time, the toggle column and the inclined toggle groove will drive the toggle shaft column to drive the turntable to rotate, so that the nut inside the delivery port moves to the bottom of the punch. This method allows the punch to descend for riveting and drive the guide rail to rise together, thereby achieving the effect of double-sided riveting;

[0023] When riveting, put the guide rail to be riveted into the tray, clamp it with clamping bar 2 and clamping bar 1 to ensure that the guide rail is placed stably, and drive the screw to rotate by hand-held knob so that clamping bar 1 pushes the guide rail to move. The position of the preset rivet holes on the guide rail can be adjusted so that it is aimed at the bottom of the punch and the nut, thereby achieving the riveting correction effect.

[0033] In order to make the technical solution of the present invention clearer, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0034] Example 1

[0035] like Figure 1 , Figure 2 and Figure 4As shown, a nut riveting device for a sunroof guide rail of an automobile is provided, comprising a workbench 1, a U-shaped frame 2 is fixedly connected to the rear surface of the workbench 1, a hydraulic push rod 3 is fixedly connected to the upper surface of the U-shaped frame 2, a disc 1 4 is fixedly connected to the lower surface of the output end of the hydraulic push rod 3 located inside the U-shaped frame 2, a disc 2 5 is rotatably connected to the lower surface of the disc 1 4 via a rotating shaft, a plurality of punches 6 are fixedly connected to the lower surface of the disc 2 5, two support seats 23 are fixedly connected to the lower surface of the workbench 1, and a A shrink box 24, a sliding block 25 is slidably connected inside the shrink box 24, a spring 3 26 is fixedly connected between the sliding block 25 and the shrink box 24, an L-shaped rod 27 is fixedly connected to the left side of the sliding block 25, a positioning column 1 28 is fixedly connected to the inner side of the L-shaped rod 27, a plurality of positioning holes 1 29 are opened on the outer wall of the disc 2 5, a guide column 1 36 is fixedly connected to the rear of the upper surface of the disc 1 4, the top end of the guide column 1 36 passes through the top of the U-shaped frame 2, and is slidably connected to the U-shaped frame 2;

[0036] When the device is riveting nuts, the hydraulic push rod 3 is started to drive the punch 6 to descend to achieve the riveting effect. The multiple punches 6 have different specifications and are suitable for riveting nuts of different specifications. The position of the punch 6 can be adjusted by rotating the disc 2 5, which is convenient for riveting different nuts. The rotating disc 2 5 can be positioned by using the engagement positioning of the positioning hole 29 and the positioning column 28, so that after adjusting the position of the punches 6 of different specifications to the riveting position, stable riveting can be achieved.

[0037] like Figure 5 and Figure 6 As shown, the upper surface of the workbench 1 is rotatably connected to a shaft column 7 through a rotating shaft, the outer wall of the shaft column 7 is rotatably connected to a turntable 8 through a rotating shaft, the outer wall of the shaft column 7 is fixedly connected to a sleeve 9, the outer wall of the sleeve 9 is provided with an inclined toggle groove 10, a plurality of delivery ports 43 are provided on the upper surface of the turntable 8, a plurality of positioning holes 2 30 are provided on the upper surface of the turntable 8 located inside the plurality of delivery ports 43, a movable block 31 is slidably connected inside the shaft column 7, a plurality of springs 4 32 are fixedly connected between the movable block 31 and the shaft column 7, a vertical rod 33 is fixedly connected to the upper surface of the movable block 31, the top end of the vertical rod 33 passes through the top of the shaft column 7, and is fixedly connected to a connecting piece 34, and a positioning column 2 35 is fixedly connected to the lower surface of the connecting piece 34;
