Detailed implementation manners

[0024] The present invention will be further described below in conjunction with the accompanying drawings and specific implementation manners.

[0025] As Figure 1 and 2As shown in the figure, an assembly riveting mechanism includes a frame 1. Inside the frame 1, there is a rotary indexing table 3. At the bottom of the rotary indexing table 3, there is a motor 31 connected to the rotary indexing table 3 and driving the rotary indexing table 3 to rotate. Circumferentially outside the rotary indexing table 3, there are a first feeding mechanism 11, a first feeding device 12, a second feeding device 14, a second feeding mechanism 16 with the same structure as the first feeding mechanism 11, a first riveting mechanism 17, a second riveting mechanism 18 with the same structure as the first riveting mechanism 17, a discharging mechanism 19, and a conveying mechanism 20. On the conveying mechanism 20, there is a first mounting bracket 6. The discharging mechanism 19 is installed on the first mounting bracket 6. On the rotary indexing table 3, a plurality of fixture mechanisms 4 are evenly arranged. On the rotary indexing table 3, there is an avoidance device 5 arranged between the first positioning mechanism 13 and the second feeding device 14 and cooperating with the second feeding device. The first feeding mechanism 11 feeds part one. The first feeding device 12 sends part one into the fixture mechanism 4 and positions it. The motor 31 drives the rotary indexing table 3 to rotate, rotates the fixture mechanism 4 with part one installed to the place where the sheet metal part is manually placed, and the operator places the sheet metal part into the fixture mechanism 4. The rotary indexing table 3 rotates to the second feeding device 14 and the second feeding mechanism 16. The second feeding mechanism 16 feeds part two. The second feeding device 14 sends part two into the fixture mechanism 4 and positions part two together with the avoidance device 5. After positioning, the rotary indexing table 3 rotates to the first riveting mechanism 17. The first riveting mechanism 17 rivets part one. After riveting, the rotary indexing table 3 rotates to the second riveting mechanism 18. The second riveting mechanism 18 rivets part two. After riveting, the discharging mechanism 19 transfers the sheet metal part with part one and part two installed into the conveying mechanism 20, realizing the full automation of riveting the sheet metal parts, and improving the work efficiency and riveting effect.

[0026] On this basis, as Figure 3 and 4As shown, the fixture mechanism 4 includes a fixture plate 41 and a fixture 42. A first spring is arranged in the middle of the fixture plate 41. The fixture 42 is arranged in the fixture plate 41 and can move up and down through the first spring. A first chute 411 is arranged on one side of the fixture 42. A positioning groove 412, a first movable block 413 and a second spring 414 are arranged in the first chute 411. One end of the second spring 414 is connected to the first movable block 413, and the other end of the second spring 414 is fixed on the fixture 42. It also includes a first cylinder arranged at the bottom of the fixture plate 41 and connected to the first movable block 413 and driving the first movable block 413 to slide horizontally in the first chute 411. A positioning hole 415, a second movable block 416, a third spring and a second cylinder 417 are arranged on the other side of the fixture 42. A pin connected to the second movable block 416 is arranged in the positioning hole 415. The third spring is arranged between the second movable block 416 and the second cylinder 417. Positioning blocks 418 are arranged on both sides of the second movable block 416. Groove structures are arranged at both ends of the second movable block 416. Positioning beads matched with the groove structures are arranged on both sides inside the positioning blocks 418. The first cylinder drives the first movable block 413 to move rightward in the first chute 411. The first feeding mechanism 12 sends the first part into the positioning groove 412. After placing is completed, the first cylinder drives the first movable block 413 to move leftward in the first chute 411 to position the first part in the positioning groove 412. The second spring 414 acts on the first movable block 413. The sheet metal part is manually placed on the fixture 42. The avoidance device 5 presses the second movable block 416 downward. The positioning beads arranged on both sides inside the positioning blocks 418 are stuck in the groove structures arranged at both ends of the second movable block 416. The second movable block 416 moving downward drives the pin connected to the second movable block 416 to move downward as well. The second feeding mechanism 14 places the second part in the positioning hole 415 for positioning, realizing the rapid positioning of the first part and the second part to the sheet metal part and improving the work efficiency.

[0027] On this basis, as Figure 5 shown, the first feeding mechanism 11 includes a vibrating bowl 111 and a feeding plate 112 arranged on the vibrating bowl 111. A material blocking and distributing device 113 is arranged on the feeding plate 112. A first sensor 114 is arranged at one end of the feeding plate 112 away from the vibrating bowl 111. When the first sensor 114 senses that the first part on the feeding plate 112 is full, the material blocking and distributing device 113 works and the vibrating bowl 111 stops feeding, improving the work efficiency.

[0028] On this basis, as Figure 6As shown in the figure, the first feeding mechanism 12 includes a linear module 121, a third cylinder 122 arranged on the linear module 121, and a first gripper 123 arranged on the third cylinder 122. The linear module 121 drives the third cylinder 122 to move horizontally, and the third cylinder 122 drives the first gripper 123 to grab the first part on the first feeding mechanism 11 and place it on the fixture, realizing the automation of feeding and material supply and improving the work efficiency.

[0029] On this basis, as Figure 7 shown, the second feeding mechanism 14 includes a fourth cylinder 141, a fifth cylinder 142 driven by the fourth cylinder 141 and arranged perpendicular to the fourth cylinder 141, and a second gripper 143 arranged at one end of the fifth cylinder 142 and driven by the fifth cylinder 142. The fourth cylinder 141 drives the fifth cylinder 142 to move back and forth, and the fifth cylinder 142 drives the second gripper 143 to grab the second part on the second feeding mechanism and place it on the fixture, realizing the automation of feeding and material supply and improving the work efficiency.

[0030] On this basis, as Figure 8 shown, the first riveting mechanism 17 includes a fixing plate 171, a gas-liquid intensifying cylinder 172 arranged on the fixing plate 171, and a riveting head 173 arranged on the gas-liquid intensifying cylinder 172 and driven by the gas-liquid intensifying cylinder 172. A limiting mechanism 174 cooperating with the riveting head 173 is also arranged on the fixing plate 171. The gas-liquid intensifying cylinder 172 drives the riveting head 173 to move downward, the limiting mechanism 174 positions the fixture, and the riveting head 173 rivets the first part in the fixture. The fixture moves downward under the action of the first spring. When the fixture touches the lower hard limit, the gas-liquid intensifying cylinder 172 continues to move downward to complete the riveting of the first part. The working principle of the second riveting mechanism 18 for riveting the second part is the same as that of the first riveting mechanism 17 for riveting the first part, achieving rapid riveting of the first part and the second part on the sheet metal part and improving the work efficiency.

[0031] On this basis, as Figure 9 shown, the discharging mechanism 19 includes an X-axis module 191, a Y-axis module 192 arranged on the X-axis module 191, and a second mounting bracket 193 arranged on the Y-axis module 192. A rotary cylinder 194 is arranged on the second mounting bracket 193, and a mounting plate 195 is mounted on the rotary cylinder 194. A sixth cylinder 196 arranged perpendicular to the rotary cylinder 194 is mounted on the mounting plate 195, and a third gripper 197 is arranged at one end of the sixth cylinder 196. Movements in two directions of the X-axis and the Y-axis are realized, improving the work efficiency of the discharging mechanism 19.

[0032] On this basis, as Figure 10As shown in the figure, the conveying mechanism 20 includes a frame 201, a conveying line 202 and a tray 203 arranged on the frame 201. A blocking device 204 is arranged between the tray 203 and the conveying line 202. A guiding device 205 and a sensor group 206 are respectively arranged at both ends of the tray on the frame 201. The guiding device 205 guides the sheet metal parts. When the sensor group 206 senses that the sheet metal parts on the tray 203 are full, the discharging mechanism 19 stops working. The conveying line 202 drives the tray 203 to move forward by a distance of one tray 203, and the blocking device 204 extends to block the tray. When the full tray is conveyed to the end of the conveying line 202, the staff removes the tray 203 to complete the work.
