Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present application.

[0032] Example 1: Please refer to Figure 1-6 The utility model provides a technical solution: a buffer device for a riveting machine, comprising: a body 1; a platform 11, arranged on the top of the body 1; a boss 12, arranged on the top of the platform 11; a turntable 13, arranged on the top of the boss 12; a fixed plate 14, arranged on the outer side wall of the turntable 13; a placement component 4, arranged above the fixed plate 14, used to bear the weight of the workpiece; a riveting component 3, arranged above the platform 11, used to rivet and link the workpiece on the placement component 4; a buffer component 2, arranged on the top of the fixed plate 14, used to cooperate with the riveting component 3 to buffer the workpiece on the placement component 4.

[0033] The placement assembly 4 includes a placement plate 41, which is slidably connected to the outer side of the turntable 13, and a placement groove 42 is provided on the top of the placement plate 41, and a positioning hole 43 is provided on the inner bottom wall of the placement groove 42; the riveting assembly 3 includes a lifting rod 31, which is slidably connected to the machine body 1, and a connecting block 32 is fixedly connected to the bottom of the lifting rod 31, and a riveting machine head 33 is fixedly connected to the bottom of the connecting block 32; the buffer assembly 2 includes two pairs of telescopic rods 21, and the telescopic rods 21 are fixedly connected to the bottom of the placement plate 41, and the top of the fixed plate 14 is provided with a telescopic groove 22 adapted to the telescopic rod 21. The bottom ends of the retractable rods 21 pass through the telescopic grooves 22, and two inner grooves 23 are provided at the top of the fixed plate 14, and compression springs 24 are fixedly connected between the inner grooves 23 and the placement plate 41; the top of the platform 11 is fixedly connected to the fixed frame 5, and the bottom of the fixed frame 5 is fixedly connected to the driving machine 51, the top of the driving machine 51 passes through the side wall of the fixed frame 5 and is fixedly connected to the driving block 52, and the top of the driving block 52 is fixedly connected to the contact rod 53; the bottom ends of the telescopic rods 21 are fixedly connected to the clamping strips 6, and the bottom of the fixed plate 14 is provided with clamping grooves 61; the top of the body 1 is fixedly connected to the cylinder 7, and the telescopic end of the cylinder 7 is fixedly connected to the lifting rod 31.

[0034] The present scheme is specifically as follows: by placing the workpiece to be riveted on the top of the placement plate 41 through the placement groove 42, the workpiece to be riveted slides downward through the positioning hole 43 and fits into the placement groove 42, by rotating the turntable 13, the turntable 13 drives the workpiece to be riveted to rotate toward the riveting assembly 3 through the placement plate 41, so that the workpiece to be riveted is under the riveting assembly 3, and the cylinder 7 is started.
