[0020] All features disclosed in this specification, or steps in all methods or processes disclosed herein, may be combined in any way, except for mutually exclusive features and / or steps.

[0021] Any feature disclosed in this specification (including any appended claims, abstract, and drawings) may be replaced by other equivalent or similar features, unless specifically stated otherwise. That is, unless specifically stated otherwise, each feature is merely one example of a series of equivalent or similar features.

[0022] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, this utility model discloses a high-speed automatic cyclic riveting device, comprising a base 11, a panel 7, and a platform 1. The platform 1 and the panel 7 are positioned one above the other on the base 11. The outer surface of the platform 1 has multiple mounting grooves 13, and the inner wall of the mounting grooves 13 has a rectangular opening 15 vertically arranged. Each mounting groove 13 contains a mold 2, and the center of each mold 2 has a model opening that communicates with the rectangular opening 15 and matches the workpiece. The panel 7 has a positioning groove facing the mold cavity 4, and each positioning groove contains a positioning seat 5. The other end of each positioning seat 5 passes through the rectangular opening 15 and is inserted into the model opening. The positioning seat 5 and the model opening are combined to form the mold cavity 4. One end of the base 11 is equipped with a drive mechanism that drives the platform 1 to rotate, and the other end of the base 11 is equipped with a riveting mechanism. Both the drive mechanism and the riveting mechanism are controlled by a microcontroller. The microcontroller can control the operation of the drive mechanism and the riveting mechanism, so that the platform can be in a state of rotation and stop. The retraction and extension distance of the second cylinder is limited, which can better push out the workpiece and disassemble and assemble the mold and the positioning seat.

[0023] In this embodiment, the riveting mechanism includes a first cylinder 10, a first motor 9, and a riveting head 8. The first cylinder 10 is mounted on the other end of the base 11. The piston rod of the first cylinder 10 passes through the base 11 and is fixedly connected to the first motor 9. The riveting head 8 is mounted on the rotating shaft of the first motor 9.

[0024] In this embodiment, the drive mechanism includes a second motor and a shaft 17. The second motor is embedded in the base 11. A shaft hole is provided at the center of the panel 7. One end of the shaft 17 is installed at the center of the platform 1, and the other end is fixedly connected to the shaft of the second motor through a coupling.

[0025] In this embodiment, a plurality of second cylinders 16 are installed on one end face of the platform 1 facing the panel 7, and the piston rods of the second cylinders 16 are installed on the panel 7.

[0026] In this embodiment, both sides of the mounting groove 13 are provided with limiting grooves 14, and both sides of the mold 2 protrude to form limiting parts 3. The limiting parts 3 are slidably disposed in the limiting grooves 14. The limiting parts and limiting grooves can position the mold vertically, and the positioning seat can restrict the mold in the mounting groove, preventing it from moving outward.

[0027] In this embodiment, the upper surface of the mold 2 is flush with the upper surface of the platform 1 to ensure the flatness of the surface.

[0028] In this embodiment, spaces are formed between the panel 7 and the platform 1, and between the panel 7 and the base 11, for the panel 7 to move up and down.

[0029] In use, the workpiece can be directly placed into the mold cavity. The mold can position the workpiece, and the second motor can drive the shaft and platform to rotate. The rotation of the platform drives the workpiece, allowing the workpiece to pass under the riveting head one by one. After rotating to the bottom of the riveting head, it will pause for a period of time. The first motor can drive the riveting head to rotate, and the first cylinder can drive the rotating riveting head to descend, pressing and flanging the riveted parts on the tool.

[0030] The second motor drives the platform to rotate continuously, allowing the workpiece to pass through the riveting head repeatedly and to undergo multiple pressing operations, thus increasing the quality of the processing.

[0031] After processing is completed, the second cylinder can be activated, causing the piston rod of the second cylinder to retract and drive the panel to rise. The movement of the panel drives the positioning seat, and the rising positioning seat can directly eject the workpiece from the mold cavity, which facilitates material removal.

[0032] When the mold or positioning seat wears out, the second cylinder can be activated to extend the piston rod of the second cylinder. At this time, the panel can be lowered. As the panel is lowered, the positioning seat can be moved out of the mold opening and the rectangular opening. After the positioning seat is lifted, the positioning seat can be taken out of the positioning groove, which facilitates the disassembly of the positioning seat. The mold can be taken out of the mounting groove along the limiting groove, which also facilitates disassembly.

[0033] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any changes or substitutions conceived without inventive effort should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope defined in the claims.
