The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0052] Example 1

[0053] like Figures 1-6As shown, this embodiment provides an automotive slide rail riveting device for riveting a pre-riveting rivet 910 to a slide rail 800 to be riveted. The device includes a transfer module, a riveting machine module 100, and a pre-pressing module 200. The transfer module includes a transfer base and a riveting machine frame 310, which can move relative to the transfer base in a horizontal plane. The riveting machine module 100 includes a riveting machine body 110, a spindle sensor 120, and a pressure sensor 150. The riveting machine body 110 is movably mounted on the riveting machine frame 310, and can move relative to the riveting machine frame 310 along a first direction Z and rotate around the first direction Z. The riveting machine body 110 is equipped with a riveting head 111 for riveting the pre-riveting rivet 910. The spindle sensor 120 is used to monitor the position of the riveting head 111, and the pressure sensor 150 is used to monitor the output force of the riveting machine body 110. The pre-pressure module 200 includes a pre-pressure head 240 and a displacement sensor 220. The pre-pressure head 240 is movably mounted on the riveting machine frame 310. The pre-pressure head 240 can move relative to the riveting machine frame 310 along the first direction Z. The pre-pressure head 240 can press against the riveting slide rail 800. The displacement sensor 220 is used to monitor the position of the pre-pressure head 240. The first direction Z is perpendicular to the horizontal plane.

[0054] The automotive slide rail riveting device achieves position adjustment of the riveting machine body 110 in the horizontal plane by setting a transfer module, ensuring that the riveting position of the riveting head 111 is adjustable. With the help of the riveting machine module 100 and the pre-pressure module 200, the reference position can be accurately located, allowing the riveting head 111 to move downwards while rotating, thus completing the riveting operation on the pre-riveting rivet 910. The pressure sensor 150, in conjunction with the monitoring of the output force change of the riveting head 111, can determine the contact state between the riveting head 111 and the pre-riveting rivet 910. Similarly, the displacement sensor 220, in conjunction with the monitoring of the position of the pre-pressure head 240, can determine the contact state between the pre-pressure head 240 and the riveted slide rail 800. Based on this design, the reference position can be successfully located, accurately identifying the start and end positions of the riveting head 111, ensuring accurate control of the riveting process. This automotive slide rail riveting device can apply different riveting methods, improving the flexibility of riveting position and riveting scale adjustment, thereby enhancing the efficiency, accuracy, and stability of the riveting operation. This meets the needs of improving production quality and efficiency during the riveting process of the slide rail 800.

[0055] In this embodiment, the pre-riveting rivet 910 on the slide rail 800 to be riveted is deformed into a post-riveting rivet 920 after riveting by the automotive slide rail riveting device; the slide rail 800 to be riveted is an automotive seat slide rail.

[0056] In this embodiment, the riveting machine module 100 further includes a hydraulic tank 130 and a servo proportional valve 140. The hydraulic tank 130 is used to drive the riveting machine body 110, and the servo proportional valve 140 is used to adjust the speed and output force of the riveting machine body 110. The pre-pressure module 200 further includes a first cylinder 210 and a pre-pressure guide rail 230 extending along the first direction Z. The pre-pressure head 240 is slidably mounted on the pre-pressure guide rail 230, and the first cylinder 210 is used to drive the pre-pressure head 240. Specifically, the pressure sensor 150 is an oil pressure sensor. The hydraulic tank 130 serves to drive the riveting machine body 110 to move along and rotate around the first direction Z, and can also serve as a power source for the pressure output by the riveting machine body 110. The cooperation of hydraulic tank 130 and servo proportional valve 140 can control the speed, start / stop and output force of riveting machine body 110, so that riveting machine body 110 moves along a predetermined trajectory. Combined with spindle sensor 120 monitoring the position change of riveting head 111 and pressure sensor 150 monitoring the pressure change of riveting head 111, it helps to complete the riveting operation smoothly and improves the automation level of automotive slide rail riveting device.

[0057] For example, the transplanting module includes a first transplanting mechanism 300 and a second transplanting mechanism 400. The first transplanting mechanism 300 is slidably disposed on the second transplanting mechanism 400 along a second direction X, and the second transplanting mechanism 400 is slidably disposed on the transplanting base along a third direction Y. The second direction X and the third direction Y are both located in a horizontal plane and are perpendicular to each other. Specifically, the first transplanting mechanism 300 is a servo structure, and the second transplanting mechanism 400 is a pneumatic structure.

[0058] The first transplanting mechanism 300 and the second transplanting mechanism 400 have simple and reliable structures, ensuring that the transplanting module can smoothly drive the riveting frame 310 to move relative to the transplanting base in the horizontal plane, improving the flexibility of the work and helping to further improve the automation level of the automotive slide rail riveting device.

[0059] Furthermore, the second transplanting mechanism 400 includes a drive plate 410 and a second cylinder 420; the drive plate 410 is slidably mounted on a second guide rail extending in the third direction Y, the second guide rail being disposed on the transplanting base; a hydraulic buffer 411 and a pin cylinder 412 are mounted on the drive plate 410, the pin cylinder 412 selectively fixing the drive plate 410 and the second guide rail; the hydraulic buffer 411 is used to buffer the drive plate 410; the second cylinder 420 is used to drive the drive plate 410. Specifically, two hydraulic buffers 411 are provided, respectively used to buffer the forward and backward movement of the drive plate 410.

[0060] Furthermore, the first transplanting mechanism 300 includes a first guide rail 320, a servo motor 330, a lead screw 340, and a riveting frame 310; the riveting frame 310 is slidably mounted on the first guide rail 320 extending along the second direction X, the first guide rail 320 is mounted on the drive plate 410, and the servo motor 330 drives the riveting frame 310 through the lead screw 340.

[0061] The above structure is simple and compact, which helps to ensure the smooth completion of the design of the first transplanting mechanism 300 sliding on the second transplanting mechanism 400 and the second transplanting mechanism 400 sliding on the transplanting base, improves the stability of the operation, reduces the space occupied by the transplanting module, and helps to further improve the automation level of the automotive slide rail riveting device.

[0062] This embodiment also provides an automotive slide rail riveting system, including a turntable device 500 and the aforementioned automotive slide rail riveting device. The turntable device 500 includes a device base 520 and a turntable body 510 rotatably connected to the device base 520. The turntable body 510 has multiple riveting stations spaced circumferentially. Each riveting station is equipped with a slide rail clamp 511 for holding the slide rail 800 to be riveted. The device base 520 allows the multiple riveting stations to be moved sequentially to the working position. The automotive slide rail riveting device is used to process the slide rail 800 to be riveted located in the working position. By setting up the turntable device 500, the slide rail 800 to be riveted at each riveting station can sequentially pass through the working position to complete the riveting operation, ensuring the accurate positioning of the slide rail 800 to be riveted, effectively improving the efficiency of the riveting operation, and ensuring the automation level of the automotive slide rail riveting system.

[0063] This embodiment also provides a method for riveting automotive slide rails, applied to the aforementioned automotive slide rail riveting device, including the following steps:

[0064] Step 1: Install the pre-riveting rivet 910 onto the slide rail 800 to be riveted, so that the riveting head 111, which is in the initial position, is directly above the pre-riveting rivet 910.

[0065] Step 2: Use the riveting head 111 or the pre-pressing head 240 to obtain the reference position and determine the riveting dimensions.

[0066] Step 3: Control the riveting head 111 to move the riveting dimension downward while rotating.

[0067] Step 4: Control the riveting head 111 to move back to the initial position.

[0068] This automotive slide rail riveting method utilizes the riveting head 111 or the preload head 240 to obtain a reference position and determine the corresponding riveting dimension. While monitoring changes in data from the spindle sensor 120 and pressure sensor 150, the PID control of the servo proportional valve 140 drives the riveting head 111 to rotate and move downwards by the riveting dimension to complete the riveting operation. This process is well-suited to the needs of automated production, ensuring high precision and stability while effectively improving production efficiency, reducing worker workload, and providing a safe production environment.

[0069] like Figures 1-7 As shown, in this embodiment, step two includes the following detailed steps: controlling the riveting head 111 to move downward while rotating; using the pressure sensor 150 to determine whether the pressure on the riveting head 111 has changed; if yes, continue; if no, continue controlling the riveting head 111 to move downward while rotating; selecting the position of the riveting head 111 as the reference position, and selecting the riveting dimension as B.

[0070] When the riveting head 111 contacts the riveting rivet 910, the pressure sensor 150 detects the change in pressure on the riveting head 111 and sends a feedback signal to the spindle sensor 120. The spindle sensor 120 records this position as the reference position for riveting.

[0071] This embodiment obtains the reference position by monitoring the pressure and displacement of the riveting head 111. While monitoring data from the spindle sensor 120 and pressure sensor 150, the riveting position of the riveting head 111 is controlled by PID regulation of the servo proportional valve 140. The advantage of this mode is that it eliminates the need to consider the height error of the pre-riveting rivet 910, detects the riveting start point of the pre-riveting rivet 910 through pressure changes, and thus controls the accuracy of the riveting depth dimension B of the pre-riveting rivet 910. The riveting speed and pressure are controllable during the riveting process, resulting in high riveting accuracy (actual measurement accuracy is ±0.03 mm) and strong riveting reliability.

[0072] Example 2

[0073] like Figures 1-6 and Figure 8 As shown, the riveting method for automotive slide rails in this second embodiment is basically the same as that in the first embodiment. The difference is that after step one, the following steps are also included: placing the preload head 240 directly above the slide rail 800 to be riveted; step two includes the following detailed steps: controlling the preload head 240 to move downward from the preparation position, so that the preload head 240 moves to the contact position abutting against the slide rail 800 to be riveted; using the displacement sensor 220 to obtain the data of the preparation position and the contact position, calculating the reference position, selecting the riveting scale as A, and controlling the preload head 240 to reset.

[0074] When the preload head 240 comes into contact with the slide rail 800 to be riveted, the displacement sensor 220 records this position as the reference position for riveting and feeds it back to the spindle sensor 120.

[0075] This embodiment obtains the reference position by monitoring the displacement of the preload head 240. While monitoring the data from the spindle sensor 120 and pressure sensor 150, the PID control of the servo proportional valve 140 is used to control the riveting position of the riveting head 111. The advantage of this mode is that it does not need to consider the height error of the rivet 910 before riveting. Using the upper surface of the slide rail 800 to be riveted as the reference point, the remaining dimension (i.e., riveting dimension A) of the rivet 920 after riveting is controlled, the riveting speed is controllable, the riveting accuracy is high (actual measurement accuracy is ±0.03 mm), and the riveting reliability is strong.

[0076] Example 3

[0077] like Figures 1-6 and Figure 9 As shown, the riveting method for automobile sliding rails in this second embodiment is basically the same as that in the first embodiment. The difference is that step two includes the following detailed steps: the initial position is selected as the reference position, and the riveting dimension is selected as C.

[0078] This embodiment obtains the reference position by using the initial position as the origin. While monitoring data from the spindle sensor 120 and pressure sensor 150, the riveting position of the riveting head 111 is controlled by PID regulation of the servo proportional valve 140. The advantages of this method are its simplicity, practicality, controllable riveting speed, high riveting accuracy (actual measurement accuracy is ±0.05 mm), and high riveting reliability.

[0079] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation of the present invention. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively describe all embodiments here.
