[0015] (1) The present invention sets a fixing device. When the device completes riveting, cylinder 2 drives piston rod 2 to retract and drives clamp plate to move toward cylinder. At this time, the extrusion of inclined block disappears, reset spring 1 resets and drives inclined block to move downward, rack 1 moves downward at the same time, rack 1 and rack 2 are meshed with gear, so when rack 1 moves downward, rack 2 moves in the opposite direction, at this time rack 2 drives anti-warping edge plate to reset and release the fixed state. When the device needs to clamp, clamp plate moves toward workpiece, squeezes inclined block to move upward, and compresses reset spring 1 and drives rack 1 to move upward. Rack 2 moves downward under the meshing action of gear, drives anti-warping edge plate to move downward and press the top edge of workpiece. By starting and closing cylinder 2, clamping of both sides of workpiece is completed, and fixing of the top of workpiece is completed by anti-warping edge plate, preventing the edge from warping due to excessive pressure during riveting operation, thereby affecting riveting accuracy.

[0017] (3) The present invention sets an automatic switch device. When the connecting rod moves to the second position of the cylinder, the Z-shaped rod is also pulled to move to the second position of the cylinder. The Z-shaped rod is fixed to the device door, and a door plate groove is opened in the rivet box. The device door is slidably connected to the inner wall of the door plate groove. At the same time, a moving groove is opened at the top of the door plate groove, and a short rod is set at the top of the device door. A roller is rotated on the outer wall of the short rod. The outer wall of the roller fits the inner wall of the moving groove. Therefore, when the device door is pulled, the device door moves to both sides through the rotation of the roller and the pulling force of the Z-shaped rod, completing the automatic opening and closing of the device door, preventing the rivet noise from being too loud during the processing operation to affect the normal work of the staff and reduce production efficiency. At the same time, by setting the device door, the instruments in the device are effectively protected from the influence of the external environment, thereby improving work efficiency.

The other end of the return spring 2 710 is fixedly connected to the top inner wall of the riveting box 3. The bottom outer wall of rack 2 79 is fixedly connected to an anti-warping edge plate 711.

[0029] When the riveting of the device is completed, cylinder 2 71 drives piston rod 2 72 to retract and drives clamping plate 73 to move toward cylinder 2 71. At this time, the extrusion of inclined block 74 disappears, reset spring 1 75 resets, and drives inclined block 74 to move downward, rack 1 76 moves downward at the same time, rack 1 76 and rack 2 79 mesh with gear 78, so when rack 1 76 moves downward, rack 2 79 moves in the opposite direction, and rack 2 79 drives anti-warping edge plate 711 to reset and release the fixed state. When the device needs to be clamped, the clamp is Plate 73 moves toward the workpiece 10, squeezing the bevel block 74 upward, while compressing the return spring 1 75 and driving the rack 1 76 upward. The rack 2 79 moves downward under the meshing action of the gear 78, driving the anti-warping plate 711 to move downward and press the top edge of the workpiece 10. The clamping of both sides of the workpiece 10 is completed by starting and closing the cylinder 2 71. At the same time, the top of the workpiece 10 is fixed by the anti-warping plate 711 to prevent the edge from warping due to excessive pressure during the riveting operation, thereby affecting the riveting accuracy.

[0030] By providing the circular magnetic block 14, the rivet is first sucked onto the rivet head 6 during riveting, thereby avoiding the occurrence of poor riveting caused by incorrect rivet placement, improving production efficiency, reducing the operator's labor intensity, ensuring product quality, and providing convenience for mass production.

[0031] When the present embodiment is working, when the riveting work needs to be completed, the cylinder 2 71 is started, and the cylinder 2 71 drives the piston rod 2 72 to move to both sides, and drives the clamping plate 73 to move to both sides at the same time. When the clamping plate 73 leaves the workpiece 10, the inclined block 74 is squeezed out by the clamping plate 73, and is thereby driven to reset by the reset spring 1 75. When the inclined block 74 resets and moves downward, it drives the rack 1 76 to move downward, and the rack 1 76 engages with the gear 78, thereby driving the gear 78 to rotate on the fixed shaft 77, and the gear 78 moves away from the workpiece 10. One end of rack 1 76 is engaged with rack 2 79, so when rack 1 76 moves downward, rack 2 79 moves upward, and at the same time drives the anti-warping edge plate 711 to move upward. At this time, the reset spring 2 710 is reset. When it is necessary to perform riveting work on a new workpiece 10, cylinder 2 71 is started, driving piston rod 2 72 to move toward the workpiece 10, driving the clamping plate 73 to squeeze the bevel block 74 so that the anti-warping edge plate 711 moves downward. When the clamping plate 73 clamps both sides of the workpiece 10, the anti-warping edge plate 711 simultaneously presses the top of the workpiece 10.

[0032] See also Figures 1-8 On the basis of the above embodiment, another embodiment of the present invention is as follows: the outer wall of the fixing device 7 is fixedly connected to a vertical moving device 8 that can facilitate the replacement and collection of the workpiece 10, and the outer wall of the vertical moving device 8 is fixedly connected to an automatic switch device 9, wherein the vertical moving device 8 includes a connecting rod 81, a fixing plate 1 82, a fixed short shaft 1 83, a crank 84, a fixing plate 2 85, a fixed short shaft 2 86, a connecting round table 87, a slide 88 and a slide rail 89, the outer wall of the piston rod 2 72 is fixedly connected to the connecting rod 81, and the outer wall of the bottom side of the connecting rod 81 is fixedly connected to the fixing plate 1 82, two fixed plates 1 82 are provided and are symmetrically distributed on one side of the connecting rod 81, a fixed short shaft 1 83 is fixedly connected between the fixed plates 1 82, the outer wall of the fixed short shaft 1 83 is rotatably connected to a crank 84, and a fixed short shaft 2 86 is rotatably connected to the gap at the other end of the crank 84, and the outer walls of both ends of the fixed short shaft 2 86 are fixedly connected to fixed plates 2 85, and the outer wall of the fixed plate 2 85 is fixedly connected to a connecting round table 87, and the outer wall of the connecting round table 87 is fixedly connected to a slide plate 88, and the slide plate 88 is slidably connected to the inner wall of the slide rail 89, and the slide rail 89 is fixedly connected to the inner wall of the riveting box 3.

[0033] When the piston rod 2 72 moves toward the cylinder 2 71 , it drives the connecting rod 81 to move. At the same time, the fixed plate 1 82 fixed on the side of the connecting rod 81 also moves toward the cylinder 2 71 . Since a fixed short shaft 1 83 is fixed in the middle of the fixed plate 1 82 , and the crank 84 is rotatably connected to the outer wall of the fixed short shaft 1 83 , the other end of the crank 84 is rotatably connected to the fixed short shaft 2 86 , therefore, when the fixed plate 1 82 moves toward the cylinder 2 71 , the crank 84 is pulled at the same time, and the other end of the crank 84 pulls the fixed plate 2 85 to move toward the cylinder 2 71 , and the fixed plate 2 85 is fixedly connected to a round table 87, and the round table 87 slides on the slide rail 89 through the slide plate 88. When the fixed plate 2 85 is pulled to move toward the cylinder 2 71 , the fixed plate 2 85 is limited by the round table 87, so it can only drive the round table 87 to move downward, which is convenient for the staff to replace and collect the workpiece 10.

[0034] The automatic switch device 9 includes a Z-shaped rod 91, a device door 92, a door panel groove 93, a movable groove 94, a short rod 95 and a roller 96. The outer wall of the connecting rod 81 is fixedly connected to the Z-shaped rod 91, and the outer wall of the Z-shaped rod 91 is fixedly connected to the device door 92. The inner wall of the riveting box 3 is provided with a door panel groove 93, and the size of the door panel groove 93 is the same as the size of the device door 92. The top of the door panel groove 93 is provided with a movable groove 94. The top outer wall of the device door 92 is fixedly connected to the short rod 95, and the outer wall of the short rod 95 is rotatably connected to the roller 96, and the size of the roller 96 is the same as that of the movable groove 94.

[0035] When the connecting rod 81 moves toward the cylinder 2 71, the Z-shaped rod 91 is also pulled to move toward the cylinder 2 71, and the Z-shaped rod 91 is fixedly connected to the device door 92, and a door plate groove 93 is provided in the riveting box 3, and the device door 92 is slidably connected to the inner wall of the door plate groove 93. At the same time, a moving groove 94 is provided on the top of the door plate groove 93, and a short rod 95 is provided on the top of the device door 92. The outer wall of the short rod 95 is rotated with a roller 96, and the outer wall of the roller 96 is fitted with the inner wall of the moving groove 94. Therefore, when the device door 92 is pulled, the device door 92 moves to both sides through the rotation of the roller 96 and the pulling force of the Z-shaped rod 91, completing the automatic opening and closing of the device door 92, preventing the riveting noise from being too loud during the processing operation, affecting the normal work of the staff and reducing production efficiency. At the same time, by setting the device door 92, the instruments in the device are effectively protected from the influence of the external environment, thereby improving work efficiency.

[0036] When the present embodiment is working, the movement of the piston rod 2 72 drives the connecting rod 81 to move. When the connecting rod 81 moves to both sides, the fixed plate 1 82 fixed thereto will also move to both sides. The fixed plate 1 82 pulls the crank 84 to move to both sides through the fixed short shaft 1 83. The other end of the crank 84 is sleeved with a fixed short shaft 2 86. The two ends of the fixed short shaft 2 86 are fixedly connected to the outer wall of the fixed plate 2 85, and the fixed plate 2 85 is fixed to both sides of the round table 87, thereby giving the round table 87 a directional movement. The pulling force on both sides is generated at the bottom, and the round table 87 slides on the inner wall of the slide rail 89 through the slide plate 88, so it is limited by the slide rail 89 and can only move downward, thereby completing the downward movement of the support plate 11. When the device needs to be riveted, the piston rod 2 72 is driven to move toward the workpiece 10 by starting the cylinder 2 71, thereby driving the connecting rod 81 to move toward the workpiece 10, so that the crank 84 squeezes the fixed short shaft 2 86, and the round table 87 is squeezed upward by the fixed short shaft 2 86. When the workpiece 10 is moved to the left, the Z-shaped rod 91 is also moved to the right, and the workpiece 10 is moved to the right.
