A buffer mechanism is fixedly installed at the top of the fixed seat. An installation frame is slidably connected to the outside of the buffer mechanism. A gas-liquid intensifying cylinder is fixedly sleeved inside the installation frame. One end of the gas-liquid intensifying cylinder is fixedly installed with a riveting head, and a riveting concave head located on one side of the riveting head is fixedly sleeved inside the installation frame. A first guiding groove is opened at the top of the loading platform. A first limiting mechanism is fixedly installed inside the loading platform, and a second limiting mechanism is clamped inside the loading platform.
[0004] Preferably, the buffer mechanism includes a second slide rail, a first fixing plate and a second fixing plate fixedly installed on the fixed seat.

Springs are sleeved on the outer sides of both ends of the fixed rod.
[0005] Preferably, the first limiting mechanism includes a lead screw with one end rotatably connected inside the loading platform. The other end of the lead screw is rotatably connected to a third fixing plate fixedly installed on one side of the loading platform. A first limiting plate clamped inside the first guiding groove is threadedly sleeved on the outer side of the end of the lead screw far from the third fixing plate. A turntable is fixedly sleeved on the outer side of the end of the lead screw extending outside the third fixing plate.
[0006] Preferably, the second limiting mechanism includes a second limiting plate clamped inside the first guiding groove and outside the lead screw. One side of the second limiting plate is provided with a fixing block. A bolt rod is threadedly sleeved inside the fixing block. A handle is movably sleeved inside the top end of the bolt rod. A first snap ring is clamped outside one end of the handle extending out of the bolt rod. A pressing plate clamped inside the loading platform is movably sleeved outside the bottom end of the bolt rod, and a second snap ring is connected to the outside of the bottom end of the bolt rod extending out of the pressing plate.
[0007] Preferably, a second guiding groove adapted to the pressing plate is formed inside the loading platform. Beneficial effects
[0008] 1. For this liftable special-shaped riveting platform, through the combined use of the first fixing plate, the second fixing plate, the fixing rod and the spring, when the riveting platform is performing riveting operations on the workpiece and the riveting punch and the riveting recess are in contact with the workpiece, the mounting frame can compress the spring, so as to automatically compensate for the displacement of the riveting punch in the direction perpendicular to the riveting surface, so that the riveting punch will not forcibly drive the workpiece to move, thereby avoiding causing local deformation of the workpiece.
[0009] 2. For this liftable special-shaped riveting platform, the turntable can rotate the lead screw and drive the first limiting plate to move at the same time, so as to adjust the initial distance between the inner side of the workpiece and the riveting recess, making the riveting recess closer to the inner side of the workpiece, thereby reducing the displacement of the riveting recess during the riveting operation. And through the cooperation of the first limiting plate and the second limiting plate, the workpiece placed on the top of the loading platform can be clamped and limited, so that the workpiece is not easy to shift, which is convenient for performing riveting operations on the workpiece.

[0015] The following further elaborates on the present application in conjunction with the accompanying drawings and embodiments. It can be understood that the specific embodiments described herein are only used to explain the relevant utility model and do not limit the utility model. Additionally, it should be noted that for the sake of convenience of description, only the parts related to the utility model are shown in the drawings.
[0016] The accompanying drawings in the embodiments of the present utility model: Different types of cross-hatching in the figure are not marked according to the national standard, nor are the materials of the components required. It is to distinguish the cross-sectional views of the components in the figure.
[0017] Please refer to Figures 1-3 , a liftable special-shaped riveting platform, including a loading platform 1, a slide seat 3 slidably connected to one side of the loading platform 1 through a first slide rail 2, an electric telescopic rod 4 fixedly sleeved inside the slide seat 3, a fixed seat 5 fixedly sleeved outside the top end of the electric telescopic rod 4, and a guide rod 6 arranged at the bottom of the fixed seat 5 and movably sleeved inside the slide seat 3. Through the first slide rail 2, the slide seat 3 can slide along the outside of the first slide rail 2, and then the gas-liquid intensifying cylinder 9 can be manually pushed to change the riveting point of the riveting platform on the workpiece. A buffer mechanism 7 is fixedly installed at the top of the fixed seat 5. An installation bracket 8 is slidably connected to the outside of the buffer mechanism 7. A gas-liquid intensifying cylinder 9 is fixedly sleeved inside the installation bracket 8. One end of the gas-liquid intensifying cylinder 9 is fixedly installed with a riveting punch 10, and a riveting concave head 11 located on one side of the riveting punch 10 is fixedly sleeved inside the installation bracket 8. A first guide groove 12 is opened at the top of the loading platform 1. A first limiting mechanism 13 is fixedly installed inside the loading platform 1, and a second limiting mechanism 14 is clamped inside the loading platform 1.
[0018] Among them, the buffer mechanism 7 includes a second slide rail 71 fixedly installed on the fixed seat 5, a first fixed plate 72 and a second fixed plate 73. A fixed rod 74 movably sleeved inside the mounting frame 8 is fixedly sleeved between the first fixed plate 72 and the second fixed plate 73. Springs 75 are sleeved on the outer sides of both ends of the fixed rod 74. Through the second slide rail 71, the mounting frame 8 can move along the axial direction of the fixed rod 74 when subjected to an external force, and the elastic force of the spring 75 can drive the mounting frame 8 to reset and buffer the mounting frame 8 at the same time, so that when the riveting punch 10 and the riveting recess 11 contact the workpiece, displacement compensation can be carried out through the movement of the mounting frame 8, avoiding the forced pushing of the workpiece by the riveting punch 10 or the riveting recess 11.
[0019] Among them, the first limiting mechanism 13 includes a lead screw 131 whose one end is rotatably connected inside the loading platform 1. The outer side of the other end of the lead screw 131 is rotatably connected to a third fixed plate 132 fixedly installed on one side of the loading platform 1. A first limiting plate 133 clamped inside the first guide groove 12 is threadedly sleeved on the outer side of the end of the lead screw 131 far from the third fixed plate 132. A turntable 134 is fixedly sleeved on the outer side of the end of the lead screw 131 extending outside the third fixed plate 132. By rotating the turntable 134, the lead screw 131 can be rotated while driving the first limiting plate 133 to move along the inner side of the first guide groove 12 and the distance between the inner side of the workpiece and the riveting punch 10 can be adjusted.
[0020] Among them, the second limiting mechanism 14 includes a second limiting plate 141 clamped inside the first guide groove 12 and located on the outer side of the lead screw 131. A fixed block 142 is arranged on one side of the second limiting plate 141. A bolt rod 143 is threadedly sleeved inside the fixed block 142. A handle 144 is movably sleeved inside the top end of the bolt rod 143. A first snap ring 145 is clamped on the outer side of the end of the handle 144 extending outside the bolt rod 143. A pressure plate 146 clamped inside the loading platform 1 is movably sleeved on the outer side of the bottom end of the bolt rod 143. A second snap ring 147 is connected to the outer side of the bottom end of the bolt rod 143 extending outside the pressure plate 146. By rotating the handle 144, the bolt rod 143 can be loosened while the limit of the pressure plate 146 on the second limiting plate 141 can be released, so that the second limiting plate 141 can move along the inner side of the first guide groove 12 and the initial distance between the first limiting plate 133 and the second limiting plate 141 can be adjusted according to the size specification of the workpiece, so as to clamp and fix the workpiece on the top of the loading platform 1 while driving the first limiting plate 133 to move by rotating the lead screw 131.
[0021] Among them, a second guiding groove 15 adapted to the pressing plate 146 is formed inside the loading platform 1. Through the second guiding groove 15, when the second limiting plate 141 is pushed, the pressing plate 146 can move synchronously along the inner side of the second guiding groove 15, and the pressing plate 146 is tightly fixed inside the first guiding groove 12 by tightening the bolt rod 143, ensuring that the second limiting plate 141 will not move by itself.
[0022] When the riveting platform works, the workpiece is placed on the loading platform 1 and positioned between the first limiting plate 133 and the second limiting plate 141. While the turntable 134 rotates the lead screw 131, the first limiting plate 133 is driven to move. Through the cooperation of the first limiting plate 133 and the second limiting plate 141, the workpiece is clamped and fixed on the loading platform 1. The electric telescopic rod 4 drives the mounting frame 8 to move downward while adjusting the heights of the riveting punch 10 and the riveting recess 11. After the height adjustment is completed, the gas-liquid boosting cylinder 9 is started. The gas-liquid boosting cylinder 9 drives the riveting punch 10 to move while extruding and riveting the workpiece part located between the riveting punch 10 and the riveting recess 11 to form a shape. The gas-liquid boosting cylinder 9 is driven in the reverse direction to drive the riveting punch 10 to reset. The mounting frame 8 pushes the gas-liquid boosting cylinder 9 to displace the riveting punch 10 and the riveting recess 11 to the next riveting point.
