[0028] In order to make the above objects, features, and advantages of the present utility model more obvious and understandable, the following will describe the detailed implementation manner of the present utility model in conjunction with the accompanying drawings.

[0029] As Figure 1 shown, the embodiment of the present application provides an automobile front-end frame riveting device, including a frame 1, in which there are provided a profiling carrier table 2 for fixing the automobile front-end frame, a clamping mechanism 3 for clamping the automobile front end, a rotating mechanism 4 for driving the profiling carrier table 2 to rotate, two symmetrically arranged nut feeding mechanisms 5 for feeding nuts, and two symmetrically arranged riveting mechanisms 6 for riveting the automobile front-end frame. The clamping mechanism 3 is installed on the profiling carrier table 2, the driving end of the rotating mechanism 4 is connected to the bottom of the profiling carrier table 2, and the nut feeding mechanism 5 is located at the side end of the profiling carrier table 2.

[0030] As Figure 2As shown in the figure, the riveting mechanism 6 includes a three-axis driving mechanism 61 and a riveting assembly 62. The driving end of the three-axis driving mechanism 61 is connected to the riveting assembly 62. The riveting assembly 62 includes a fixing plate 621, a first cylinder 622 and a riveting gun 623. A driving plate 614 is arranged on the driving end of the three-axis driving mechanism 61. The fixing plate 621 is slidably connected to the driving plate 614. The first cylinder 622 is installed on the driving plate 614. The driving end of the first cylinder 622 is connected to the fixing plate 621. The riveting gun 623 is installed on the fixing plate 621. The first cylinder 622 is used to drive the riveting gun 623 to move up and down.

[0031] Specifically, the front-end frame of the vehicle is fixed on the profiling carrier table 2, and then the clamping mechanism 3 clamps the front-end frame of the vehicle on the profiling carrier table 2. The three-axis driving mechanisms 61 of the two riveting mechanisms 6 respectively drive the riveting assemblies 62 to move above the first nut positioning assembly 54 or the second nut positioning assembly 55 of the two nut feeding mechanisms 5. Then the first cylinder 622 drives the riveting gun 623 to move downward. The riveting gun 623 rotates clockwise so that the nut in the first nut positioning assembly 54 or the second nut positioning assembly 55 is sleeved on the riveting gun 623. Then the two three-axis driving mechanisms 61 drive the riveting assemblies 62 to move above the front-end frame of the vehicle. The third cylinder 553 drives the riveting gun 623 to drive the nut to extend into the riveting hole of the front-end frame of the vehicle. The riveting gun 623 first rotates counterclockwise and then clockwise to pull the nut, and the end close to the nut cap is stacked in the riveting hole, so that the nut is fixed in the riveting hole. When riveting the riveting holes on the side end of the front-end frame of the vehicle, the rotating mechanism 4 drives the profiling carrier table 2 to drive the front-end frame of the vehicle to rotate, so that the riveting holes on the side end of the front-end frame of the vehicle are located directly below the riveting gun 623. The three-axis driving mechanism 61 drives the riveting assembly 62 to rivet and fix the picked-up nut in the riveting hole on the side end of the front-end frame of the vehicle.

[0032] In the above structure, through the mutual cooperation of the profiling carrier table 2, the clamping mechanism 3, the two riveting mechanisms 6, the two nut feeding mechanisms 5 and the rotating mechanism 4, the automatic riveting of each part of the front-end frame of the vehicle is realized, and the production efficiency is greatly improved, and the labor and time costs are saved.

[0033] As Figure 2 As shown in the figure, in one embodiment, a camera assembly 63 for photographing and positioning the nut holes on the front-end frame of the vehicle is arranged on the fixing plate 621 of the front-end frame riveting equipment of the vehicle. The camera assembly 63 includes a camera 631 and a light source 632. The camera 631 and the light source 632 are respectively installed on the side end of the fixing plate 621. The camera 631 is located directly above the light source 632. The light source 632 is used to illuminate the camera 631.

[0034] Specifically, when the front-end frame of the vehicle is fixed on the profiling carrier table 2, the three-axis drive mechanism 61 drives the camera assembly 63 to take pictures and position the riveting holes on the front-end frame of the vehicle. After determining the position, the three-axis drive mechanism 61 drives the rivet gun 623 to drive the nut to rivet the riveting holes on the front-end frame of the vehicle. Among them, the light source 632 illuminates the camera 631, improving the clarity of the picture taken by the camera 631. This setting greatly improves the riveting accuracy of the rivet gun 623 and can avoid riveting deviation caused by factors such as rotation.

[0035] As Figure 3 shown, in one embodiment, the nut feeding mechanism 5 of the front-end frame riveting device of the vehicle includes a vibrating bowl 51, a first linear vibrator 52, a second linear vibrator 53, a first nut positioning component 54, and a second nut positioning component 55. The vibrating bowl 51 is respectively connected to the first linear vibrator 52 and the second linear vibrator 53. The first linear vibrator 52 is connected to the first nut positioning component 54, and the second linear vibrator 53 is connected to the second nut positioning component 55.

[0036] Specifically, the vibrating bowl 51 can feed two different specifications of nuts respectively. The two different specifications of nuts can flow into the first nut positioning component 54 and the second nut positioning component 55 through the first linear vibrator 52 and the second linear vibrator 53 respectively. This setting improves the efficiency of nut feeding and also improves the versatility of positioning different specifications of nuts.

[0037] As Figure 3 and Figure 4 shown, in one embodiment, the first nut positioning component 54 of the front-end frame riveting device of the vehicle includes a rotary cylinder 541, a first positioning seat 542, an arc-shaped positioning portion 543, a second cylinder 544, and a first positioning head 545. A first through hole 001 for accommodating the arc-shaped positioning portion 543, a second through hole for the first positioning head 545 to move, and a first connection port 003 adapted to the discharge port of the first linear vibrator 52 are provided on the first positioning seat 542. The rotary cylinder 541 and the second cylinder 544 are respectively installed at the bottom of the first positioning seat 542. The driving end of the rotary cylinder 541 is connected to the arc-shaped positioning portion 543. A first positioning groove 004 for accommodating the nut is provided on the arc-shaped positioning portion 543. The driving end of the second cylinder 544 is connected to the first positioning head 545. The second cylinder 544 is used to drive the first positioning head 545 to pass through the second through hole to position the nut in the first positioning groove 004 of the arc-shaped positioning portion 543.

[0038] Specifically, the rotary cylinder 541 drives the arc-shaped positioning portion 543 to rotate within the first through-hole 001 of the first positioning seat 542. When the first positioning groove 004 of the arc-shaped positioning portion 543 corresponds to the first connection port 003 of the first positioning seat 542, the nut within the first linear vibrator 52 flows into the first positioning groove 004 through the first connection port 003. Then, the rotary cylinder 541 drives the arc-shaped positioning portion 543 to drive the nut to rotate. When it rotates to the second through-hole of the first positioning seat 542, the second cylinder 544 drives the first positioning head 545 to pass through the second through-hole to fix the nut within the first positioning groove 004. This setting not only improves the positioning effect of the nut but also improves the accuracy when the riveting gun 623 picks up the nut.

[0039] As Figure 4 shown, in one of the embodiments, the second nut positioning assembly 55 of the vehicle front-end frame riveting device includes a second positioning seat 551, a positioning block 552, a third cylinder 553, a fourth cylinder 554, and a second positioning head 555. A cavity 005 for accommodating the positioning block 552, a third through-hole for the second positioning head 555 to move, and a second connection port 007 for adapting to the second linear vibrator 53 are provided on the second positioning seat 551. The third cylinder 553 is installed at the side end of the second positioning seat 551, and the driving end of the third cylinder 553 passes through the second positioning seat 551 to be connected to the positioning block 552. A second positioning groove 008 for accommodating the nut is provided on the positioning block 552. The fourth cylinder 554 is installed on one side of the second positioning seat 551, and the driving end of the fourth cylinder 554 is connected to the second positioning head 555. The fourth cylinder 554 is used to drive the second positioning head 555 to pass through the third through-hole to position the nut within the second positioning groove 008 of the positioning block 552.

[0040] Specifically, the third cylinder 553 drives the positioning block 552 to move horizontally within the cavity 005 of the second positioning seat 551. When the second positioning groove 008 of the positioning block 552 corresponds to the second connection port 007 of the second positioning seat 551, when the nut within the second linear vibrator 53 flows into the second positioning groove 008 through the second connection port 007, and when the third cylinder 553 drives the positioning block 552 to drive the nut to move to the third through-hole, the fourth cylinder 554 drives the second positioning head 555 to pass through the third through-hole to fix the nut within the second positioning groove 008. This setting not only improves the positioning effect of the nut but also improves the accuracy when the riveting gun 623 picks up the nut.

[0041] As Figure 5As shown, in one embodiment, the clamping mechanism 3 of the vehicle front-end frame riveting device includes a number of clamping components 31 arranged circumferentially along the profiling carrier table 2. The clamping component 31 includes a rotary pressing cylinder 311 and a pressing head 312. The rotary pressing cylinder 311 is installed on the profiling carrier table 2, and the driving end of the rotary pressing cylinder 311 is connected to the pressing head 312. The rotary pressing cylinder 311 is used to drive the pressing head 312 to clamp the vehicle front-end frame on the profiling carrier table 2.

[0042] Specifically, 7 clamping components 31 are arranged circumferentially along the profiling carrier table 2. The 7 rotary pressing cylinders 311 are respectively installed on the profiling carrier table 2 and are located at the side ends of the vehicle front-end frame. When the vehicle front-end frame is placed on the profiling carrier table 2, the 7 rotary pressing cylinders 311 simultaneously rotate the pressing head 312 and press the pressing head 312 against various parts of the vehicle front-end frame. This setting facilitates clamping and fixing the vehicle front-end frame on the profiling carrier table 2.

[0043] As Figure 5 shown, in one embodiment, the rotating mechanism 4 of the vehicle front-end frame riveting device includes a first motor 41, a first brake disc 42, a second brake disc 43, and a rotating shaft 44. The middle end of the rotating shaft 44 is fixedly connected to the bottom of the profiling carrier table 2. The two ends of the rotating shaft 44 are respectively connected to the first brake disc 42 and the second brake disc 43. The driving end of the first motor 41 is connected to the rotating shaft 44. The first motor 41 is used to drive the rotating shaft 44 to drive the profiling carrier table 2 to rotate. The first brake disc 42 and the second brake disc 43 are used to stop the rotating shaft 44.

[0044] Specifically, the rotating mechanism 4 is installed inside the frame 1 and is located below the profiling carrier table 2. The middle end of the rotating shaft 44 of the rotating mechanism 4 is fixedly connected to the bottom of the profiling carrier table 2. The two ends of the rotating shaft 44 are respectively connected to the first brake disc 42 and the second brake disc 43. The driving end of the first motor 41 is connected to the rotating shaft 44. The first motor 41 drives the rotating shaft 44 to drive the profiling carrier table 2 and the vehicle front-end frame to rotate. When rotated to the specified position, the first brake disc 42 and the second brake disc 43 simultaneously stop the rotating shaft 44. This setting not only realizes the multi-angle rotation of the profiling carrier table 2, but also effectively improves the fixing degree of the profiling carrier table 2 after rotation, can avoid the situation of the profiling carrier table 2 shaking during the riveting process, and at the same time improves the riveting efficiency of the device.

[0045] As Figure 5As shown, in one embodiment, four limiting components 21 for limiting the automotive front-end frame are respectively arranged at the four end corners of the profiling carrier table 2 of the automotive front-end frame riveting device. The limiting component 21 includes a sixth cylinder 211 and a limiting column 212. The sixth cylinder 211 is installed at the bottom of the profiling carrier table 2, and the driving end of the sixth cylinder 211 is connected to the limiting column 212. The sixth cylinder 211 is used to drive the limiting column 212 to extend into the bottom of the automotive front-end frame to limit the automotive front-end frame.

[0046] Specifically, when the automotive front-end frame is placed on the profiling carrier table 2, the four sixth cylinders 211 simultaneously drive the limiting columns 212 to move upward to the bottom of the automotive front-end frame to limit the automotive front-end frame. This setting enhances the effect of fixing the automotive front-end frame.

[0047] As Figure 1 shown, in one embodiment, the three-axis drive mechanism 61 of the automotive front-end frame riveting device includes a conveying component 611 that moves along the X-axis direction, a first linear module 612 that moves along the Y-axis direction, and a second linear module 613 that moves along the Z-axis direction.

[0048] Specifically, the conveying component 611 is installed at the bottom end of the top of the frame 1, the driving end of the conveying component 611 is located below, both ends of the first linear module 612 are respectively connected to the driving end of the conveying component 611, and the second linear module 613 is connected to the driving end of the first linear module 612. The conveying component 611 drives the first linear module 612 to drive the second linear module 613 to move along the X-axis direction, thereby driving the riveting component 62 to move along the X-axis direction. The first linear module 612 drives the second linear module 613 to drive the riveting component 62 to move along the Y-axis direction. The second linear module 613 drives the riveting component 62 to move up and down along the Z-axis direction. This setting facilitates driving the riveting component 62 to move in each direction, thereby improving the riveting efficiency.

[0049] As Figure 1 shown, in one embodiment, the conveying component 611 of the automotive front-end frame riveting device includes a second motor 100 and a conveying line 101.
