[0015] 1. The utility model is provided with a clamping and adjusting mechanism, an electric control guide rail, an electric control moving block, a fixed plate, a bidirectional screw, a driving motor, an adjusting block and a clamping plate. The driving motor can drive the bidirectional screw to rotate. Under the limit of the groove of the fixed plate, the adjusting block drives the clamping plate to move toward the middle to clamp and fix the workpiece. The electric control guide rail drives the electric control moving block to move, which can drive the entire clamped workpiece at the upper end to adjust the position, thereby ensuring stable clamping of the workpiece and improving the stability of the workpiece during riveting. At the same time, the workpiece can be flexibly adjusted in position according to different riveting positions of the workpiece, which greatly improves the flexibility and stability of the riveting process of the workpiece.

[0016] 2. The utility model arranges a buffer mechanism, an assembly plate, a guide rod, a movable block, a thrust spring, a movable rod, an impact plate and a damping spring rod. When riveting and stamping are performed, the impact force of the upper cylinder pressing down will be transmitted through the workbench and received by the impact plate, so that the impact plate moves downward, squeezes the damping spring rod to contract, and uses the damper to buffer the impact force in the processing. The downward movement of the impact plate will also cause the movable rod to push the movable block to the front and rear sides, so that the movable block can move stably along the guide rod, squeezing the thrust spring. Under the elastic force of the thrust spring, the impact force is buffered for a second time, which can effectively buffer the impact force generated in the processing process for multiple times, reduce the equipment vibration caused by the impact, and thus greatly improve the stability of the entire processing equipment.

[0029] Furthermore, the clamping adjustment mechanism 7 also includes adjustment blocks 706 which are located on both sides of the surface of the bidirectional screw rod 704 and are threadedly connected to the inner side of the fixing plate 703 , and a clamping plate 707 is fixedly mounted on the front end of the adjustment block 706 .

[0030] By adopting the above technical solution, the groove of the fixing plate 703 can limit the adjustment block 706, ensuring that the adjustment block 706 moves stably when the bidirectional screw rod 704 rotates.

[0031] like Figure 3-Figure 4 As shown, the buffer mechanism 8 includes a mounting plate 801 fixedly installed in the middle of the inner surface of the base 1 , and a guide rod 802 is fixedly installed inside a groove above the surface of the mounting plate 801 .

[0032] By adopting the above technical solution, the movable block 803 can move more stably when the guide rod 802 is guided.

[0033] Furthermore, the buffer mechanism 8 also includes a movable block 803 slidably arranged on the front and rear sides of the guide rod 802 surface, and a thrust spring 804 is fixedly installed on the opposite side of the surface of the movable block 803 on the outside of the guide rod 802, and the end of the thrust spring 804 is fixedly connected to the inner surface of the groove of the assembly plate 801.

After the single-point riveting of the workpiece is completed, the electric control guide rail 701 is used to drive the electric control moving block 702 to move, which can drive the entire clamped workpiece at the upper end to adjust the position, and then adjust the alignment position of the workpiece and the punch head 6 to perform multi-point adjustment riveting work. When riveting and punching, The impact force of the upper cylinder 5 pressing downward will be transmitted through the workbench 2 and received by the impact plate 806, causing the impact plate 806 to move downward, squeezing the damping spring rod 807 to contract, and using the damper to buffer the impact force during processing. The downward movement of the impact plate 806 will also cause the movable rod 805 to push the movable block 803 to the front and rear sides, so that the movable block 803 can move stably along the guide rod 802, squeezing the thrust spring 804, and under the elastic force of the thrust spring 804, the impact force is buffered for a second time, which can effectively buffer the impact force generated in the processing process for multiple times and reduce the vibration of the equipment caused by the impact. This is the working principle of the riveting machine that is convenient for fixing parts.
