[0025] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0026] Reference Figure 1-6 The automatic locking and riveting device of this utility model includes a base plate 1. The top of the base plate 1 is fixedly connected to a mounting plate 2 via a fixing frame 8. The bottom of the mounting plate 2 is set as an open structure. A cylinder 15 is fixedly connected to the top inside the mounting plate 2. A pressure rod 16 is fixedly connected to the bottom end of the piston rod of the cylinder 15. The cooperation of the cylinder 15 and the pressure rod 16 is used to provide the downward pressure required for riveting.

[0027] A storage cylinder 3 is fixedly connected to the top of the mounting plate 2 and to one side of the cylinder 15. The storage cylinder 3 has open ends. A feeding assembly is provided inside the mounting plate 2 and at the bottom of the storage cylinder 3. The feeding assembly includes two sliding rods 17 movably connected inside the mounting plate 2, two connecting rods 18 symmetrically fixed between the sliding rods 17, two guide rods 19 symmetrically fixed between the connecting rods 18, and two movable plates 21 symmetrically slidably connected to the outside of the guide rods 19. Two springs are symmetrically provided on opposite sides of each movable plate 21. Spring 20 is sleeved on the outside of the corresponding guide rod 19. The adjacent side of the movable plate 21 is provided with a semi-circular positioning groove 22, which forms a frustum structure. The first electric push rod 4 is fixedly connected inside the mounting plate 2 on the side away from the pressure rod 16. The slide rod 17 near the first electric push rod 4 is fixedly connected to the piston rod of the first electric push rod 4. Two slide grooves 23 are symmetrically opened inside the mounting plate 2 on the side near the slide rod 17. Both ends of the slide rod 17 are slidably connected inside the corresponding slide groove 23.

[0028] The riveted parts to be riveted are fed into the storage cylinder 3 for storage and retrieval. After the riveted parts fall into the positioning groove 22, the first electric push rod 4 pushes the slide rod 17 and its movable plate 21 to move. The moving movable plate 21 moves the riveted parts inside the positioning groove 22 to below the pressure rod 16. The first electric push rod 4 pushes the pressure rod 16 downward. As the pressure rod 16 presses down on the riveted parts, it can push the movable plate 21 to move away under the action of the inclined surface of the positioning groove 22. Thus, the riveted parts can move smoothly downward through the pressure of the pressure rod 16 and perform the riveting work. After the riveting work is completed, the pressure rod 16 returns to its original position. The spring 20 pushes the movable plate 21 to move and fit together. The first electric push rod 4 drives the movable plate 21 to return to the bottom of the storage cylinder 3. The riveted parts inside the storage cylinder 3 can fall into the positioning groove 22 for the next feeding work. This realizes the automatic feeding and riveting of the riveted parts, which helps to improve production efficiency.

[0029] The tops of the slide rod 17, connecting rod 18, and movable plate 21 are flush. The top of the piston rod of the first electric push rod 4 is flush with the top of the slide rod 17. The flush top of the movable plate 21 ensures smooth sliding at the bottom of the storage cylinder 3. The piston rod of the first electric push rod 4 also provides support so that when the movable plate 21 moves to the bottom of the pressure rod 16, the piston rod of the first electric push rod 4 can support and block the riveted parts inside the storage cylinder 3.

[0030] In order to achieve the rotation and positioning of the workpiece, a rotating shaft 10 is rotatably connected inside the base plate 1. A turntable 5 located below the mounting plate 2 is fixedly connected to the top of the rotating shaft 10. Multiple positioning plates 6 are evenly fixedly connected to the top of the turntable 5. A motor 9 is fixedly connected to the top of the base plate 1. The bottom end of the rotating shaft 10 is fixedly connected to the output shaft of the motor 9.

[0031] The positioning plate 6 is used to place and position the workpiece. Driven by the motor 9, it can drive the rotating shaft 10 and the turntable 5 to rotate together, thereby realizing the rotation and repositioning of the workpiece and facilitating the loading and unloading of the workpiece.

[0032] Both the turntable 5 and the positioning plate 6 have through holes 7 inside. The through holes 7 of the turntable 5 and the positioning plate 6 are arranged vertically opposite each other. A second electric push rod 11 is connected inside the base plate 1 and on the side close to the mounting plate 2. A connecting plate 14 is fixedly connected to the top of the piston rod of the second electric push rod 11. Two push rods 12 are fixedly connected to the top of the connecting plate 14. The push rods 12 can be inserted into the corresponding through holes 7.

[0033] When the piston rod of the second electric push rod 11 extends, it will push the connecting plate 14 and the push rod 12 to rise together, so that the push rod 12 can be engaged with the corresponding through hole 7, thereby realizing the ejection of the workpiece. This avoids the workpiece after riveting being stuck inside the positioning plate 6, making the subsequent unloading of the workpiece smoother and more convenient.

[0034] In order to support the turntable 5 and ensure the stability of the riveting process, a support plate 13 is fixedly connected to the top of the base plate 1 and below the pressure rod 16. The top of the support plate 13 is slidably connected to the bottom of the turntable 5, and the support plate 13 can support the pressure points of the turntable 5 and the pressure rod 16.

[0035] Working principle: The workpiece is placed inside the positioning plate 6, and the riveted parts to be riveted are fed into the storage cylinder 3 for storage and retrieval. Driven by the motor 9, the rotating shaft 10 and the turntable 5 can be rotated together, thereby realizing the rotation and repositioning of the workpiece;

[0036] When the workpiece moves below the pressure rod 16, the first electric push rod 4 pushes the slide rod 17 and its movable plate 21 to move. The moving movable plate 21 moves the riveting parts inside the positioning groove 22 to below the pressure rod 16. The first electric push rod 4 pushes the pressure rod 16 downwards. Simultaneously, the pressure rod 16 presses down on the riveting parts, and under the action of the inclined surface of the positioning groove 22, it can push the movable plate 21 to move away, allowing the riveting parts to move smoothly downwards and be riveted. After the riveting is completed, the pressure rod 16 returns to its original position, the spring 20 pushes the movable plate 21 to move and engage, and the first electric push rod 4 drives the movable plate 21 back to the bottom of the storage cylinder 3. The riveting parts inside the storage cylinder 3 can then fall into the positioning groove 22 for the next feeding operation, realizing automatic feeding and riveting of the riveting parts, which helps improve production efficiency.

[0037] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
