[0032] like Figures 1-8 As shown in the figure, this utility model embodiment provides an automatic riveting machine.

[0033] An automatic riveting machine includes a machine base 1, a linear vibration feeding mechanism 2, a flexible vibration feeding mechanism 3, a riveting mechanism 4, and a unloading mechanism 5. A rotary table mechanism 6 is provided on the machine base 1, and a plurality of riveting fixtures 7 are provided on the rotary table mechanism 6. The linear vibration feeding mechanism 2, the flexible vibration feeding mechanism 3, the riveting mechanism 4, and the unloading mechanism 5 are sequentially arranged around the outside of the rotary table mechanism 6. A first gripper feeding assembly 8 is provided between the linear vibration feeding mechanism 2 and the rotary table. A transfer platform 9 is provided between the flexible vibration feeding mechanism and the rotary table mechanism 6. A second gripper feeding assembly 10 is provided between the transfer platform 9 and the rotary table mechanism 6.

[0034] This invention achieves a fully automated process from parts loading to riveting and unloading by integrating a direct vibration feeding mechanism 2, a flexible vibration feeding mechanism 3, a rotary table mechanism 6, and corresponding gripper feeding components. The multi-station design allows for simultaneous operation of various processes, significantly reducing the processing time for individual products and improving overall production efficiency. This invention features a specially designed flexible vibration feeding mechanism 3, equipped with a transfer table 9 and a second gripper feeding component 10, which can identify the material's orientation, enhancing the equipment's material handling capabilities. The layout of all components around the rotary table mechanism 6 not only saves floor space but also optimizes the collaborative work between components, reduces material transport paths, and further improves work efficiency.

[0035] The automatic riveting machine described in this embodiment includes a riveting fixture 7 comprising a base 11 and a base 12.

The two pushing mechanisms 19 are respectively located inside the direct vibration feeding mechanism 2 and the unloading mechanism 5. The pushing mechanisms 19 are correspondingly disposed with the inner connecting plate. Specifically, by combining the movable part 14 with the spring 15, when the material is being fed by the direct vibration feeding mechanism 2 and when the material is being unloaded by the unloading mechanism 5, the inner connecting plate can be pushed by the pushing mechanism 19, allowing the fixed plate 16 to exit the receiving groove 13, so that the material can be smoothly put in and taken out. After the pushing mechanism 19 releases the inner connecting plate, the fixed plate 16 re-enters the receiving groove 13 and is locked in place with the material.

[0037] like Figure 8 As shown, it can be understood that the material conveyed by the direct vibration feeding mechanism 2 is the conductive column 100, and the material conveyed by the flexible vibration feeding mechanism 3 is the terminal 101. When the terminal 101 is being fed, it can be placed around the outer periphery of the conductive column 100 without moving the fixed plate 16.

[0038] The automatic riveting machine described in this embodiment includes a movable component 14 comprising an outer connecting plate 20 and an inner connecting plate 21.

A spring 15 is disposed between the inner connecting plate 21 and the outer wall of the base 12, and the spring 15 is sleeved on the movable rod 22. A fixed plate 16 is disposed at one end of the outer connecting plate 20 near the base 12. Specifically, the movable rod 22 passes through the base 12 and connects to the inner and outer connecting plates, working in conjunction with the spring 15 to ensure stable clamping of the workpiece. The movable rod 22 guides the spring 15. It can be understood that there are two movable rods 22, which are respectively connected to the outer connecting plate 20 and the two sides of the inner connecting plate 21.

Specifically, the combination of the stand 23, the lifting drive cylinder 24, and the riveting head 25 enables precise and powerful riveting operations, ensuring that each workpiece receives high-quality riveting treatment.

[0040] The automatic riveting machine described in this embodiment includes a lifting mechanism 27 on the machine base 1, located at the bottom of the riveting head 25. Specifically, the lifting mechanism 27 at the bottom of the riveting head 25 provides a certain supporting force from the bottom, reducing damage to the rotary table mechanism 6 during riveting.

[0041] The automatic riveting machine described in this embodiment includes a lifting mechanism 27 comprising a base plate 28, a drive device 29, a push block 30, and a lifting block 31. The drive device 29 is disposed at the edge of the base plate 28. The top of the push block 30 is provided with an inclined surface 32. A side plate 33 is provided on the outer side of the base plate 28, and a positioning block 34 is provided on the side plate 33. The lifting block 31 is slidably connected to the positioning block 34. An abutment block 35 is provided on the top of the lifting block 31, and an abutment roller 36 is movably disposed at the bottom of the lifting block 31. The abutment roller 36 abuts against the inclined surface 32. The output end of the drive device 29 is connected to the push block 30 to drive the push block 30 to move. Specifically, the drive device 29 drives the push block 30 to move, and the inclined plane 32 and roller mechanism make the lifting block 31 move up and down. This mechanical linkage design effectively improves the stability and reliability of the lifting action. After lifting, it can provide support for the rotary table mechanism 6, and after lowering, it will not affect the rotation of the rotary table mechanism 6.

[0042] In this embodiment of the automatic riveting machine, baffles 37 are provided on both sides of the base plate 28. Limiting grooves 38 are formed on the lower inner side of each baffle 37. Limiting blocks 39 protrude from both sides of the bottom of the push block 30. Each limiting block 39 extends into the limiting groove 38 and can slide within the limiting groove 38. Specifically, the limiting grooves 38 on the baffles 37 and the limiting blocks 39 on the push block 30 cooperate with each other, restricting the movement range of the push block 30.

[0043] The automatic riveting machine described in this embodiment includes a first gripper feeding assembly 8 and a second gripper feeding assembly 10, both comprising a support plate 40, a lateral displacement assembly 41, a longitudinal displacement assembly 42, and a pneumatic gripper 43. The lateral displacement assembly 41 is disposed on the top of the support plate 40, the longitudinal displacement assembly 42 is disposed at the output end of the lateral displacement assembly 41, and the pneumatic gripper 43 is disposed at the output end of the longitudinal displacement assembly 42. Specifically, the first gripper feeding assembly 8 and the second gripper feeding assembly 10, composed of the support plate 40, the lateral displacement assembly 41, the longitudinal displacement assembly 42, and the pneumatic gripper 43, achieve automatic material gripping and placement, greatly reducing manual intervention and improving work efficiency.

[0044] The automatic riveting machine described in this embodiment includes a feeding mechanism 5 comprising a gripper feeding assembly 44 and a feeding slide 45. Both the gripper feeding assembly 44 and the feeding slide 45 are mounted on the machine base 1, with the feeding slide 45 located below the gripper feeding assembly 44. Specifically, the combined application of the gripper feeding assembly 44 and the feeding slide 45 results in a simple, stable, and durable structure, simplifying the finished product collection process.

[0045] It is understandable that the gripper unloading assembly 44 has the same structure as the first gripper loading assembly 8 and the second gripper loading assembly 10.
