[0047] See attached Figures 1 to 5As shown, the present invention provides a technical solution: a drilling and riveting assembly, including a housing 10, a riveting device 20 and a nail feeding device 30, the housing 10 has a first accommodating cavity 11 and a first side wall 12, the first side wall 12 is provided with a first opening 111 communicating with the first accommodating cavity 11; the riveting device 20 includes a first driving mechanism 21, a second driving mechanism 22, a first riveting arm 23 and a second riveting arm 24, the first driving mechanism 21 and the second driving mechanism 22 are both arranged in the first accommodating cavity 11, the second driving mechanism 22 is arranged opposite to the first driving mechanism 21, and the output end of the first driving mechanism 21 and the second driving mechanism 22 are connected to each other. The output ends of both pass through the first opening 111 and are exposed outside the shell 10, the first riveting arm 23 and the second riveting arm 24 are connected to the output ends of the two first driving mechanisms 21 and the output ends of the second driving mechanisms 22 one by one, and the end of the first riveting arm 23 away from the first driving mechanism 21 and the end of the second riveting arm 24 away from the second driving mechanism 22 are both provided with a riveting head 231; the nail feeding device 30 includes a second driving motor 31, a buffer 32, a rotating arm 33 and a clamp 34 connected in sequence, the second driving motor 31 is arranged on the output end of the first driving mechanism 21, and the rotating arm 33 is arranged opposite to the first riveting arm 23.

[0048] Exemplarily, the first driving mechanism 21 and the second driving mechanism 22 may be a cylinder, a hydraulic cylinder or an electric cylinder, etc. The buffer 32 may be a pneumatic buffer 32, a hydraulic buffer 32 or a spring buffer 32, etc. The clamp 34 may be a block rubber structure, and the block rubber structure is provided with a clamp hole having the same shape as the rivet.

[0049] According to this embodiment, the robot arm moves the drilling and riveting assembly to the workpiece, and makes the required riveting position of the workpiece located between the first riveting arm 23 and the second riveting arm 24. When feeding the nail, the second drive motor 31 drives the rotating arm 33 to rotate, and rotates the chuck 34 to the nail removal position to remove the nail. After removing the nail, the second drive motor 31 drives the rotating arm 33 to rotate the chuck 34 to the rivet hole of the workpiece and align it, and then the first drive mechanism 21 pushes the chuck 34 to abut against the workpiece, and a part of the tail of the rivet is first inserted into the rivet hole of the workpiece. Under the continuous thrust provided by the first drive mechanism 21 to the first riveting arm 23, the workpiece generates resistance to the chuck 34, so that the chuck 34 and the rotating arm 33 remain relatively stationary; because the buffer 32 is affected by the chuck 34 and the rotating arm 33, the buffer 32 is compressed, so that the riveting head 231 of the first riveting arm 23 extends into the clamping hole of the chuck 34. As the first riveting arm 23 continues to move, the riveting head 231 of the first riveting arm 23 opens the clamping hole of the clamp 34 and gradually pushes the rivet into the rivet hole of the workpiece, thereby assembling the rivet into the rivet hole of the workpiece. Before riveting, the first driving mechanism 21 drives the first riveting arm 23 to move toward the first side wall 12, so that the riveting head 231 of the first riveting arm 23 is separated from the clamping hole of the clamp 34, and the second driving motor 31 drives the rotating arm 33 to rotate and rotate the clamp 34 away from the first riveting arm 23. During riveting, the first driving mechanism 21 pushes the first riveting arm 23 to move away from the first side wall 12, so that the riveting head 231 of the first riveting arm 23 abuts the head of the rivet, and abutting force can be applied to the head of the rivet. At this time, the second driving mechanism 22 pulls the second riveting arm 24 to move toward the first side wall 12, so that the riveting head 231 of the first riveting arm 23 abuts the tail of the rivet; at the same time, the second driving mechanism 22 continues to provide pulling force to the second riveting arm 24, which can apply extrusion force to the tail of the rivet, so that the tail of the rivet is upset into a riveting head, thereby realizing riveting operation in a small space.

[0050] See attached Figures 2 to 4 As shown, in some embodiments, the shell 10 has a second side wall opposite to the first side wall 12, and the first drive mechanism 21 and the second drive mechanism 22 each independently include a first transmission component 212, a first drive motor 211, a screw rod 213, a movable arm 214 and a first sliding component 215. The first transmission component 212 is arranged outside the shell 10, and the first transmission component 212 is arranged opposite to the second side wall. The screw rod 213 is arranged parallel to the first drive motor 211. The output end of the first drive motor 211 and one end of the screw rod 213 both pass through the second side wall and are connected to the first transmission component 212. The other end of the screw rod 213 is threadedly matched with the movable arm 214. The movable arm 214 is connected to the shell 10 through the first sliding component 215, and the second drive motor 31 is arranged on the movable arm 214.

[0051] According to this embodiment, for the first driving mechanism 21 or the second driving mechanism 22, the first driving motor 211 drives the screw rod 213 to rotate through the first transmission assembly 212. Based on the threaded cooperation between the moving arm 214 and the screw rod 213, the moving arm 214 is driven to move relative to the first accommodating cavity 11, so that the first riveting arm 23 or the second riveting arm 24 moves toward or away from the first side wall 12, so that the first riveting arm 23 or the second riveting arm 24 can perform different actions. Under the cooperation of the first driving mechanism 21 and the second driving mechanism 22, the first riveting arm 23 and the second riveting arm 24 can perform the riveting action.

[0052] See attached Figure 1 As shown, in some embodiments, a protective cover 13 is provided on the second side wall, and the first transmission assembly 212 is located inside the protective cover 13 .

[0053] According to this embodiment, the protective cover 13 isolates the first transmission component 212 to prevent dust and the like from adhering to the first transmission component 212 , thereby ensuring the transmission efficiency of the first transmission component 212 .

[0054] See attached Figures 1 to 6 As shown, in some embodiments, the clamp 34 includes a connecting plate 341 and a clamping plate 342. There are two clamping plates 342. Both clamping plates 342 are rotatably disposed on the connecting plate 341. The two clamping plates 342 are arranged opposite to each other. A clamping groove 3421 is provided on the clamping surface of each clamping plate 342. After the two clamping plates 342 are closed, the two clamping grooves 3421 form a clamping hole with the same shape as a rivet. A torsion spring is provided between each clamping plate 342 and the connecting plate 341.

[0055] According to this embodiment, when the clamp 34 abuts against the workpiece and the rivet head 231 of the first rivet arm 23 is inserted into the clamp hole formed by the two clamps 342, as the first drive mechanism 21 pushes the first rivet arm 23 to continue to move away from the first side wall 12, the rivet head 231 of the first rivet arm 23 can open the two clamps 342, and at the same time, the rivet head 231 of the first rivet arm 23 can apply a thrust to the head of the rivet, so as to gradually push the rivet into the rivet hole of the workpiece. After the rivet is inserted into the rivet hole of the workpiece, the first drive mechanism 21 provides a pulling force to the first rivet arm 23, so that the rivet head 231 of the first rivet arm 23 withdraws from the clamp hole, and the two clamps 342 are reset by the torsion springs connected to them. After the clamp 34 moves away from the first rivet arm 23, the first drive mechanism 21 and the second drive mechanism 22 perform the rivet action again. In this way, when the rivet head 231 of the first rivet pressing arm 23 pushes the rivet, the rivet can reduce the influence of resistance, ensuring that the rivet can smoothly enter the riveting hole of the workpiece.

[0056] See attached Figure 1 and 7As shown, in some embodiments, the drilling and riveting assembly includes a nail blowing device, which includes a third driving mechanism 41 and a nail feeding tube 42 , and the nail feeding tube 42 is disposed at the output end of the third driving mechanism 41 .

[0057] Exemplarily, the third driving mechanism 41 may be a pneumatic cylinder, a hydraulic cylinder, an electric cylinder, or the like.

[0058] According to this embodiment, the nail feeding tube 42 can be connected to the external air pipe. When the clamping hole of the chuck 34 is aligned with the nail feeding tube 42, the third driving mechanism 41 pushes the output end of the nail feeding tube 42 to abut against the chuck 34. At the same time, rivets are placed on the external bellows, and air is blown into the external air pipe and the nail feeding tube 42 through the blowing device; under the influence of the gas, the rivets are inserted into the clamping hole of the chuck 34. In this way, automatic nail feeding can be further realized without manual participation, thereby reducing labor intensity.

[0059] See attached Figure 1 and 8 As shown, in some embodiments, the shell 10 has a second accommodating chamber 14, the second accommodating chamber 14 is arranged parallel to the first accommodating chamber 11, the first side wall 12 is provided with a second opening 141 connected to the second accommodating chamber 14, the drilling and riveting assembly includes a drilling device 50, the drilling device 50 is arranged in the second accommodating chamber 14, the drilling device 50 includes a driving component 53, a support seat 51 and a drilling machine 52, the support seat 51 is arranged at the output end of the driving component 53, and the drilling machine 52 is arranged on the support seat 51.

[0060] Exemplarily, the driving component 53 may be a pneumatic cylinder, a hydraulic cylinder, an electric cylinder, or the like.

[0061] According to this embodiment, when the drilling machine 52 corresponds to the drilling position required by the workpiece, the driving component 53 pushes the support seat 51 to drive the drilling machine 52 to pass through the second opening 141 and continue to move toward the drilling position required by the workpiece. As the drilling machine 52 continues to move, the drilling machine 52 drills the drilling position required by the workpiece. In this way, the integration of drilling and riveting can be achieved, which can not only improve work efficiency, but also reduce the economic cost of the equipment.

[0062] See attached Figure 8 As shown, in some embodiments, the driving component 53 includes a mounting seat 531, a ball screw spline pair 532 and a fourth driving mechanism 533, there are two mounting seats 531, the two mounting seats 531 are fixed to the inner wall of the second accommodating chamber 14, the nut and the spline nut of the ball screw spline pair 532 are connected to the two mounting seats 531 one by one, the fourth driving mechanism 533 includes a third driving motor 5331 and a second transmission assembly 5332, the third driving motor 5331 is arranged on a mounting seat 531, and the second transmission assembly 5332 is connected to the output end of the third driving motor 5331 and the nut of the ball screw spline pair 532.

[0063] Exemplarily, the nut of the ball screw spline pair 532 is rotatably connected to one mounting seat 531 ; in this embodiment, when the fifth driving mechanism 534 is not provided, the spline nut of the ball screw spline pair 532 is fixed to another mounting seat 531 .

[0064] According to this embodiment, the third drive motor 5331 drives the second transmission assembly 5332 to drive the nut of the ball screw spline pair 532 to rotate, and the spline nut of the ball screw spline pair 532 generates resistance to the ball screw. The nut of the ball screw spline pair 532 keeps the ball screw moving in a straight line, so that the drilling machine 52 can drill or retreat into the second accommodating chamber 14.

[0065] See attached Figure 8 As shown, in some embodiments, the driving component 53 includes a fifth driving mechanism 534, the structure of the fifth driving mechanism 534 is the same as that of the fourth driving mechanism 533, the third driving motor 5331 of the fifth driving mechanism 534 is arranged on another mounting seat 531, and the second transmission assembly 5332 of the fifth driving mechanism 534 is connected to the spline nut of the ball screw spline pair 532.

[0066] Exemplarily, the nut of the ball screw spline pair 532 is rotatably connected to one mounting seat 531 , and the spline nut of the ball screw spline pair 532 is rotatably connected to the other mounting seat 531 .

[0067] According to this embodiment, the fifth driving mechanism 534 drives the second transmission assembly 5332 to drive the spline nut of the ball screw spline pair 532 to rotate, so that the spline nut of the ball screw spline pair 532 drives the ball screw of the ball screw spline pair 532 to rotate, thereby adjusting the angle of the drilling machine 52 and allowing the drill bit of the drilling machine 52 to accurately correspond to the drilling position required by the workpiece.

[0068] See attached Figure 1 and 9 As shown in Figures 10 to 10, in some embodiments, a mounting groove 15 is provided at the top of the shell 10, and the drilling and riveting assembly includes a floating device 60, which is disposed in the mounting groove 15. The floating device 60 includes a first support plate 61, a second support plate 62, a reset assembly 63 and a second sliding assembly 64. The first support plate 61 is fixed to the bottom wall of the mounting groove 15, and the second sliding assembly 64 is at least one pair. The reset assembly 63 and each pair of second sliding assemblies 64 are disposed between the first support plate 61 and the second support plate 62, and the reset assembly 63 is disposed between each pair of second sliding assemblies 64.

[0069] Exemplarily, the reset assembly 63 may be a pneumatic buffer 32 , a hydraulic buffer 32 , a spring buffer 32 , or the like.

[0070] According to this embodiment, due to the difference in thickness of the workpieces of the same product or the assembly error, there is a relative position difference between the set position of the first riveting arm 23 and the riveting surface of the workpiece. Therefore, during the riveting process, after the first riveting arm 23 has pushed the rivet into the rivet hole of the workpiece, since the first riveting arm 23 will continue to move a distance, by abutting the first riveting arm 23 against the riveting surface of the workpiece, the housing 10 moves relative to the robot arm, driving the reset assembly 63 to compress, and then can adapt to the relative position change caused by the difference in the workpieces, avoiding the first riveting arm 23 causing the workpiece to deform. After the riveting is completed, the reset assembly 63 can drive the housing 10 and the riveting device 20 to reset.

[0071] See attached Fig.10 As shown, in some embodiments, the reset assembly 63 includes a baffle 631, a guide rod 632, a guide block 633 and an elastic member 634.
