In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0069] This embodiment provides a riveting device for riveting the bottom of a box body and riveting the top of the box body and a top plate. The box body includes three side faces connected in sequence, namely a first side face, a second side face, and a third side face, and the three side faces are connected to form a shape with a "C" cross-section. Connecting structures are provided on both sides of the bottom of the second side face of the box body, and the connecting structures need to be riveted to the first side face and the second side face to rivet the bottom of the box body; the top of the box body needs to be riveted to the corresponding three side faces of the top plate.

[0070] As Figure 1-3As shown, the riveting device includes a rotating device 1, a first upper riveting tooling 2, a first lower riveting tooling 3, and a second upper riveting tooling 4. The rotating device 1 includes a rotating turntable 11, and the turntable 11 is driven by a driving mechanism to rotate. A plurality of positioning toolings 12 are arranged circumferentially on the turntable 11. The positioning toolings 12 are used to position the box body. The top plate is placed on the top of the box body to form a workpiece to be riveted. The first upper riveting tooling 2 and the first lower riveting tooling 3 are arranged on the rotation path of the positioning tooling 12 of the rotating device 1. The first upper riveting tooling 2 and the first lower riveting tooling 3 are arranged opposite to each other and are respectively located above and below the positioning tooling 12. The first upper riveting tooling 2 and the first lower riveting tooling 3 can respectively abut against the top and bottom of the workpiece to be riveted, and respectively rivet the first area on the top of the workpiece to be riveted and the bottom of the box body. The second upper riveting tooling 4 is arranged on the rotation path of the positioning tooling 12 of the rotating device 1 and is located above the positioning tooling 12. The second upper riveting tooling 4 can rivet the second area on the top of the workpiece to be riveted.

[0071] When the rotating tooling drives the workpiece to be riveted to rotate to the positions where the first upper riveting tooling 2 and the first lower riveting tooling 3 are located, the first upper riveting tooling 2 and the first lower riveting tooling 3 can respectively abut against the top and bottom of the workpiece to be riveted to facilitate riveting the first area on the top of the workpiece to be riveted and the bottom of the box body. When the positioning tooling 12 rotates to the position where the second upper riveting tooling 4 is located, the second upper riveting tooling 4 can rivet the second area on the top of the workpiece to be riveted, thereby realizing the riveting of the box body and the top plate. This riveting device realizes the automatic riveting of the box body and the top plate, improving the production efficiency.

[0072] Preferably, a plurality of positioning toolings 12 are evenly arranged circumferentially on the turntable 11, so that by rotating the turntable 11 by the same angle, the riveting toolings at different positions can work simultaneously, improving the work efficiency. Specifically, the positioning tooling 12 is provided with a groove having a "C" - shaped cross - section, and the box body is installed in the "C" - shaped groove to limit the box body. In this embodiment, as Figure 3 shown, three positioning toolings 12 are evenly arranged circumferentially on the turntable 11.

[0073] Optionally, the rotating device 1 further includes a locking mechanism 13. A locking mechanism 13 is provided on each positioning tooling 12. The locking mechanism 13 can lock the box body on the positioning tooling 12. The rotating device 1 can lock the box body on the positioning tooling 12 through the locking mechanism 13, avoiding the risk of the box body falling during the rotation of the turntable 11. Specifically, the locking mechanism 13 is rotatably arranged on the positioning tooling 12. The locking mechanism 13 can be in a vertical and horizontal state. When the locking mechanism 13 is in the horizontal state, it can abut the box body in the "C"-shaped groove of the positioning tooling 12 to prevent the box body from coming out. When the locking mechanism 13 is in the vertical state, the locking mechanism 13 is separated from the box body, so that the box body can be taken out of the positioning tooling 12. The rotation of the locking mechanism 13 can be realized by motor drive to achieve automation.

[0074] Optionally, the riveting device further includes a support assembly 5. The support assembly 5 includes a support table 51 and a support frame 52.

The first riveting assembly 24 includes a third mounting table 241 and a first riveting mechanism 242. The two groups of third mounting tables 241 are respectively along the second direction ( Figure 4The first upper riveting tool 2 can realize the movement of the first riveting mechanism 242 in the vertical direction through the setting of the first driving device 22. The two groups of first riveting components 24 are arranged in the first direction. The third mounting platforms 241 of the two groups of first riveting components 24 are each driven by a second driving device 26 to move along the second direction on the second mounting platform 23. The first riveting mechanism 242 can be driven by the third driving device 27 to move along the first direction on the corresponding third mounting platform 241, thereby realizing the three-dimensional movement of the first riveting mechanism 242, which is more flexible in operation and has a wider adaptability. In this embodiment, each group of third mounting platforms 241 is respectively moved in the second direction by a group of second driving devices 26, and each group of first riveting mechanisms 242 is respectively moved in the first direction by a group of third driving devices 27. The two-dimensional movement (movement in the first direction and the second direction) of the first riveting mechanisms 242 of the two groups of first riveting assemblies 24 can be achieved independently, so that the movement of the two groups of first riveting mechanisms 242 is more flexible.

[0076] Optionally, the first upper riveting tool 2 further includes a pressing assembly (not shown in the figure), which is arranged at the bottom of the second mounting platform 23 and can move with the second mounting platform 23 to abut against the top of the workpiece to be riveted or detach from the workpiece to be riveted. The setting of the pressing assembly can press the top plate of the component to be riveted against the box body to prevent the top plate from moving or deforming during the riveting process.

[0077] Optionally, in order to realize the movement of the two groups of first riveting components 24 of the first upper riveting tool 2 in the vertical direction and avoid skewed movement, in this embodiment, two guide rails 28 are arranged in parallel on the second mounting platform 23, and the guide rails 28 extend in the vertical direction. Correspondingly, guide holes are arranged on the first mounting platform 21 at positions corresponding to the guide rails 28. The guide rails 28 are passed through the guide holes and can move in the guide holes.

Specifically, the limiting mechanism 35 includes a stop plate and a driving part. The output end of the driving part is connected to the stop plate. The driving part drives the stop plate to move along the fourth direction so that the stop plate abuts against the bottom of the box body, thereby limiting the bottom of the box body. The structure of the limiting mechanism 35 is not specifically limited herein as long as it can limit the bottom of the box body.

[0082] In this embodiment, the structure of the second upper riveting tooling 4 is the same as that of the first upper riveting tooling 2, but the number of sets of the corresponding punch 2423 and die 2422 is slightly different. The number of sets of the second riveting mechanism 342 can be set according to actual riveting needs. The specific structure of the second upper riveting tooling 4 will not be elaborated herein.

The control system can store the riveting parameters of the equipment. When replacing the workpiece to be riveted, the riveting equipment can automatically adjust the corresponding parameters, programs, and usage functions.

[0085] Riveting process:

[0086] First, install the box body on the positioning tooling 12. The "C" opening of the box body faces the inside of the positioning tooling 12, and then place the top plate above the box body to form the workpiece to be riveted.

[0087] Then, the limiting mechanism 35 is started, and the limiting mechanism 35 is used to lock the box body on the positioning tool 12.

[0088] Afterwards, the turntable 11 rotates so that when the positioning fixture 12 on which the workpiece to be riveted is installed rotates to the position of the first upper riveting fixture 2 and the first lower riveting fixture 3, the rotation stops, and the first upper riveting fixture 2 and the first lower riveting fixture 3 respectively abut against the workpiece to be riveted, and the second side surface and the top plate of the box are riveted through the first upper riveting fixture 2; the two connecting structures on the second side surface of the box are riveted to the first side surface and the third side surface through the first lower riveting fixture 3.

[0089] Afterwards, the first upper riveting tool 2 and the first lower riveting tool 3 are reset, and the turntable 11 continues to rotate, driving the positioning tool 12 to rotate to the position of the second upper riveting tool 4 and stop. The second upper riveting tool 4 rivets the other two side surfaces of the box body and the top plate to the top plate. It should be noted that the riveting directions of the two groups of second riveting mechanisms 342 are set in opposite directions to ensure the stability of the box body.

[0090] Afterwards, the riveted workpiece is cut into pieces.

[0091] It should be noted that when the turntable 11 stops rotating, the three positioning jigs 12 work simultaneously, one of the positioning jigs 12 is loading materials, and the operator installs the box body and the top plate on the positioning jig 12, and the other positioning jig 12 rivets the first area of ​​the box body and the top plate through the first upper riveting jig 2, and rivets the bottom of the box body through the first lower riveting jig 3, and the third positioning jig 12 rivets the second area of ​​the box body and the top plate through the second upper riveting jig 4. Different functions are realized in different riveting jig positions, and work can be carried out simultaneously at the same time to improve work efficiency.
