[0021] Please refer to Figure 2 The present invention provides an automatic riveting machine, including a frame 1, two sets of side riveting mechanisms 2, two sets of front and rear riveting mechanisms 3, and a positioning fixture 4 for positioning and placing connector 10, etc. Each set of side riveting mechanisms 2 includes a side riveting head 21 and a side riveting drive device, and each set of front and rear riveting mechanisms 3 includes several front and rear riveting heads 31 and front and rear riveting drive devices. The components of this embodiment will be described in detail below with reference to the accompanying drawings.
[0022] like Figure 2 and Figure 3 As shown, the positioning fixture 4 can be fixedly installed on the top surface of the workbench of the frame 1. Two sets of side riveting mechanisms 2 are respectively mirror-symmetrically arranged on the left and right sides of the positioning fixture 4, and two sets of front and rear riveting mechanisms 3 are respectively axially symmetrically arranged on the front and rear sides of the positioning fixture 4 corresponding to the center of the positioning fixture 4.
[0023] Preferably, the top surface of the positioning fixture 4 may be provided with a contour groove for limiting the horizontal movement of the connector 10. The shape of the contour groove matches the contour of the vertical bottom section of the connector 10. The positioning fixture 4 ensures the precise positioning of the connector 10 through the contour groove design, avoiding positional deviation during the riveting process.
[0024] Among them, the two sets of side riveting mechanisms 2 are designed with mirror symmetry, which can simultaneously rivet the side riveting holes 101 on the left and right sides of the connector 10; the two sets of front and rear riveting mechanisms 3 are designed with axisymmetric symmetry, which can simultaneously rivet multiple front and rear riveting holes 102 on the front and rear sides of the connector 10, thereby improving production efficiency.
[0025] like Figure 4 As shown, the side riveting head 21 is connected to the side riveting drive device. The side riveting drive device can drive the side riveting head 21 to move horizontally to get closer to or away from the side riveting hole 101 of the connector 10 on the positioning fixture 4. The side riveting drive device realizes precise control and rapid reset of the side riveting head 21.
[0026] In this embodiment, the lateral riveting drive device may include a lateral base 22, a lateral riveting drive cylinder 23, a lateral connecting block 24, and a lateral sliding module. The lateral base 22 is fixedly installed on the top surface of the workbench of the frame 1. The lateral connecting block 24 is movably mounted on the lateral base 22 through the lateral sliding module. The lateral riveting drive cylinder 23 is fixedly mounted on the lateral sliding module. The output shaft of the lateral riveting drive cylinder 23 is fixedly connected to the end of the top surface of the lateral connecting block 24. The rear end of the lateral riveting head 21 is fixedly engaged in the first strip groove 241 at the front end of the lateral connecting block 24 by bolts.

[0027] Furthermore, the lateral sliding module may include a lateral fixing plate 251, a lateral sliding cylinder 252, a lateral support plate 253, a first slider rail assembly 254, and a second slider rail assembly 255.

The output shaft of the lateral sliding cylinder 252 is connected to one side of the first cylinder mounting plate 231 via a transmission connection. The bottom of the lateral connecting block 24 is movably fixed to the other end of the lateral support plate 253 near the positioning fixture 4 via the second slider rail assembly 255.
[0028] In practice, the lateral sliding cylinder 252 is activated, which drives the lateral support plate 253 to move horizontally through the first slider slide rail assembly 254, causing the side riveting head 21 and the lateral riveting drive cylinder 23 to move closer to the side riveting hole 101 until the side punch 210 is aligned with the hole. Then, the output shaft of the lateral riveting drive cylinder 23 pushes the lateral connecting block 24, which drives the side riveting head 21 to apply pressure to the side spring piece 111 in the side riveting hole 101, thus completing the riveting operation.
[0029] like Figure 5 As shown, both the front and rear riveting heads 31 are connected to the front and rear riveting drive device. The front and rear riveting drive device can drive the corresponding front and rear riveting heads 31 to move in the horizontal direction to approach or move away from the several front and rear riveting holes 102 of the connector 10 on the positioning fixture 4.
[0030] In this embodiment, the front and rear riveting drive device may include a front and rear base 32, a front and rear riveting drive cylinder 33, a front and rear connecting block 34, and a front and rear sliding module. The front and rear base 32 is fixedly installed on the top surface of the workbench of the frame 1. The front and rear connecting block 34 is movably mounted on the front and rear base 32 through the front and rear sliding module. The front and rear riveting drive cylinder 33 is fixedly mounted on the front and rear sliding module. The output shaft of the front and rear riveting drive cylinder 33 is fixedly connected to the top end of the front and rear connecting block 34. The rear ends of the front and rear riveting heads 31 are fixedly clamped in the second strip groove 341 at the front end of the front and rear connecting block 34 by bolts. The ends of the front and rear riveting heads 31 have several front and rear punches 310 that correspond to the front and rear riveting holes 102 of the connector 10 respectively.
[0031] Specifically, the forward and backward sliding module may include a forward and backward fixed plate 351, a forward and backward sliding cylinder 352, a forward and backward support plate 353, a third slider rail assembly 354, and a fourth slider rail assembly 355. The forward and backward fixed plate 351 is fixedly disposed on the top of the forward and backward base 32. The forward and backward sliding cylinder 352 is fixedly connected to one end of the forward and backward fixed plate 351. The bottom of the forward and backward support plate 353 is movably disposed on the forward and backward fixed plate 351 through the third slider rail assembly 354. The forward and backward riveting drive cylinder 33 is fixedly connected to the top of one end of the forward and backward support plate 353 through its second cylinder mounting plate 331. The output shaft of the forward and backward sliding cylinder 352 is connected to one side of the second cylinder mounting plate 331. The bottom of the forward and backward connecting block 34 is movably fixed to the other end of the forward and backward support plate 353 near the positioning fixture 4 through the fourth slider rail assembly 355.
[0032] In practice, the forward and backward sliding cylinder 352 is activated, which drives the forward and backward support plate 253 to move horizontally through the third slider slide rail assembly 354, so that the forward and backward riveting heads 31 move closer to the forward and backward riveting holes 102 of the connector 10 until the forward and backward punches 210 are aligned with each hole. The output shaft of the forward and backward riveting drive cylinder 33 pushes the forward and backward connecting block 34, which drives multiple forward and backward riveting heads 310 to apply pressure to the forward and backward spring pieces 112 of the forward and backward riveting holes 102 at the same time, thus completing the riveting operation.
[0033] The connector 10 in this embodiment adopts a 1*4case connector with a single row of 4 pins. The connector has a side connection hole 101 on both the left and right sides, and four sets of front and rear riveting holes 102 on the front and rear sides. Each set has three front and rear riveting points. Therefore, the end of the side pressing head 21 is provided with a side punch 210, and the end of the front and rear pressing head 31 is provided with three front and rear punches 310.
[0034] To facilitate operators' monitoring of equipment operation status, a display 5 and control buttons may also be included. The display 5 is mounted above the top surface of the workbench of the rack 1. The control buttons include a start button 61 and an emergency stop button 62, both located at the bottom of the display 5. The start button 61 is used to start the equipment, and the emergency stop button 62 can quickly cut off the equipment in case of abnormality or emergency, ensuring the safety of the equipment and personnel.
[0035] The working principle of this embodiment is as follows:
[0036] like Figure 6 As shown, firstly, the connector 10, pre-installed with two side springs 111 and two front and rear springs 112, is placed in the contour groove of the positioning fixture 4. The contour groove restricts its horizontal movement to complete the positioning. Next, the start button 61 is pressed, simultaneously activating the side riveting mechanism 2 and the front and rear riveting mechanism 3. At this time, the two lateral sliding cylinders 252 respectively drive the lateral support plate 253 to move via the first slider rail assembly 254, causing the side riveting head 21 to approach and align with the side riveting hole 101 pre-installed with the hook of the side spring 111. Subsequently, the lateral riveting drive cylinder 23 pushes the side riveting head 21 to complete the lateral riveting of the side spring piece 111. The two front and rear sliding cylinders 352 drive the front and rear support plates 353 to move through the third slider slide rail assembly 354, so that the front and rear riveting heads 31 are aligned with the front and rear riveting holes 102 pre-installed with the hooks of the front and rear spring pieces 112. Then, the front and rear riveting drive cylinder 33 pushes to complete the front and rear riveting of the front and rear spring pieces 112. Throughout the process, the operator monitors the status through the display 5. In case of emergency, the operator can stop the machine using the emergency stop button 62.
[0037] In summary, this utility model, through its symmetrically arranged side riveting mechanism and front and rear riveting mechanism, can simultaneously rivet multiple riveting points of the connector, ensuring the riveting position accuracy and uniform force of multiple spring pieces, effectively avoiding spring piece position deviation. Compared with traditional manual point-by-point riveting, it significantly improves production efficiency, ensures stable and consistent riveting quality, and meets the needs of large-scale production.
