[0021] Example
[0022] refer to Figures 1 to 5The riveting device for lightweight, high-strength SMC products described in this embodiment includes a base 1. A first power component 4 is provided on one side of the base 1. A movable frame 2 is slidably connected to the base 1 via the first power component 4. A rivet gun head 12 is connected to one side of the movable frame 2. An installation mechanism 13 is provided between the rivet gun head 12 and the movable frame 2. A positioning component 16 is fixedly connected to the side of the rivet gun head 12 away from the movable frame 2. A fixing frame 8 is fixedly connected to the base 1 on one side of the movable frame 2. Both sides of the top of the fixing frame 8 are fixedly connected to... There is a first cylinder 9, and the output end of the first cylinder 9 is fixedly connected to a first positioning plate 10. A pressure sensor is installed on the first positioning plate 10. A first guide rod 11 is fixedly connected to one side of the first positioning plate 10. The first guide rod 11 is slidably connected to the fixing frame 8. The first cylinder 9 drives the first positioning plate 10 to move. The two first positioning plates 10 move to fix the SMC material. Through the improvement, the operator does not need to disassemble the entire riveting device. The gun head can be quickly replaced with simple operation. Ordinary operators can complete the gun head replacement after simple training.
[0023] refer to Figure 1 and Figure 5 The first power assembly 4 includes a first motor 41, which is fixedly connected to one side of the base 1. A first gear 42 is fixedly connected to the output end of the first motor 41. A second gear 43 is meshed with one side of the first gear 42. A first lead screw 44 is fixedly connected to one side of the second gear 43. The first lead screw 44 is rotatably connected inside the base 1. One side of the moving frame 2 is threadedly connected to the first lead screw 44. By setting the first power assembly 4, the first motor 41 drives the first gear 42 to rotate, the first gear 42 drives the second gear 43 to rotate, and the second gear 43 drives the first lead screw 44 to rotate, thereby driving the moving frame 2 to slide on the base 1, so that the rivet gun head 12 can move the material. It should be noted that a high-precision servo motor is selected as the power source. This motor has the characteristics of fast response speed, high control accuracy, and stable torque. By cooperating with the control system, the rivet force and rivet speed can be precisely controlled according to the rivet process requirements, avoiding damage to SMC products due to excessive rivet force.
[0024] refer to Figure 1 and Figure 5The base 1 has a first sliding groove 5 on one side of its top end. One side of the movable frame 2 is slidably connected to the first sliding groove 5. The first lead screw 44 is rotatably connected inside the first sliding groove 5. The first guide groove 6 is provided on both sides of the first sliding groove 5. A first guide block 7 is slidably connected inside the first guide groove 6. One side of the first guide block 7 is fixedly connected to one side of the movable frame 2. A first guide rod 11 is fixedly connected to one side of the first positioning plate 10. The first guide rod 11 is slidably connected to the fixed frame 8. By setting the first sliding groove 5, the movable frame 2 can move horizontally under the action of the first lead screw 44. The first guide block 7 and the first guide groove 6 make the sliding of the movable frame 2 on the base 1 more stable. The first guide rod 11 makes the movement of the first positioning plate 10 driven by the first cylinder 9 more stable and less prone to deviation.
[0025] refer to Figure 4 The mounting mechanism 13 includes a connecting groove 132, which is located on one side of the movable frame 2. A connecting block 131 is inserted into the connecting groove 132, and one side of the connecting block 131 is fixedly connected to one side of the rivet gun head 12. A positioning groove 133 is provided inside the connecting block 131, and a positioning block 134 is inserted into the positioning groove 133. A second power assembly 135 is provided on one side of the top of the movable frame 2. The positioning block 134 is fixedly connected to the positioning groove 133 through the second power assembly 135. The second power assembly 135 includes a frame 1354, which is fixedly connected to one side of the top of the movable frame 2. A second lead screw 13 is rotatably connected inside the frame 1354. 51. A torsion wheel 1352 is fixedly connected to the top of the second lead screw 1351, and a sliding plate 1353 is threadedly connected to the outer surface of the second lead screw 1351. The sliding plate 1353 is slidably connected inside the frame 1354. By setting the installation mechanism 13, when it is necessary to remove the rivet gun head 12, the torsion wheel 1352 is rotated to drive the second lead screw 1351 to rotate, so that the sliding plate 1353 on the surface of the second lead screw 1351 moves. The sliding plate 1353 drives the positioning block 134 to move, so that the positioning rod leaves the positioning hole of the connecting block 131, and the connecting block 131 is released from the connecting groove 132. Thus, the rivet gun head 12 can be removed from the moving frame 2 for replacement or maintenance, saving disassembly time, reducing disassembly complexity, and improving maintenance efficiency.
[0026] refer to Figure 4 The frame 1354 has a second guide groove 14 on both sides inside. A second guide block 15 is slidably connected inside the second guide groove 14. One side of the second guide block 15 is fixedly connected to one side of the slide plate 1353. By setting the second guide groove 14 and the second guide block 15, the slide plate 1353 moves more stably under the action of the second lead screw 1351, avoiding the slide plate 1353 from shifting its sliding position, which is beneficial for the positioning rod to connect to the positioning hole.
[0027] refer to Figure 3 The positioning component 16 includes a second cylinder 161, which is fixedly connected to one side of the top end of the rivet gun head 12. A second positioning plate 162 is fixedly connected to the output end of the second cylinder 161. A pressure sensor is also installed on the second positioning plate 162, which is slidably connected inside the rivet gun head 12. A second guide rod 163 is fixedly connected to both sides of the top end of the second positioning plate 162, and the second guide rod 163 is slidably connected to the rivet gun head 12. By setting the positioning component 16, the other side of the workpiece is placed into the rivet gun head 12. The second cylinder 161 drives the second positioning plate 162 to move. The second positioning plate 162 moves stably under the action of the second guide rod 163, and the workpiece is fixed by the second positioning plate 162, which facilitates the movement of the workpiece by the first power component 4.
[0028] Operating principle and advantages: The lightweight, high-strength SMC product to be processed is placed on the base 1, and its position is roughly adjusted so that it is between the two first positioning plates 10. The output end of the first cylinder 9 pushes the first positioning plate 10 to move, and the two first positioning plates 10 move towards each other from both sides, gradually approaching the SMC product until it is tightly clamped and fixed. During this process, the clamping force of the first cylinder 9 is monitored in real time by a pressure sensor and fed back to the control system to ensure that the clamping force is appropriate, which can fix the product without causing damage. The output end of the first motor 41 drives the first gear 4 The rotation of cylinder 2 drives the second gear 43 to rotate, which in turn drives the first lead screw 44 to rotate in the first groove 5 within the base 1. This drives the movable frame 2 to slide on the base 1. The sliding of the movable frame 2 causes the rivet gun head 12 connected to one side of it to move, gradually approaching the part to be riveted. When the rivet gun head 12 moves to the appropriate position, the output end of the second cylinder 161 pushes the second positioning plate 162 to slide inside the rivet gun head 12. The second guide rods 163 on both sides of the top of the second positioning plate 162 ensure its stable movement. The other side of the SMC product is fixed to facilitate subsequent riveting operations. When the riveting gun head 12 wears out or needs to be replaced with a different specification gun head to meet new processing requirements, the operator rotates the torsion wheel 1352 at the top of the frame 1354 in the mounting mechanism 13. The torsion wheel 1352 drives the second lead screw 1351 to rotate. The slide plate 1353, which is threaded to the outer surface of the second lead screw 1351, moves inside the frame 1354. Since the second guide blocks 15, which are slidably connected in the second guide grooves 14 on both sides of the frame 1354, are connected to the slide plate 1353, the movement of the slide plate 1353 is ensured. When the movement is stable, the sliding plate 1353 moves, causing the positioning rod to move and disengage from the positioning hole of the connecting block 131, thus releasing the connection between the connecting block 131 and the connecting groove 132. At this point, the rivet gun head 12 can be removed from the moving frame 2. The connecting block 131 of the new rivet gun head 12 is inserted into the connecting groove 132 of the moving frame 2, ensuring that the connecting block 131 and the connecting groove 132 fit tightly. Then, the torsion wheel 1352 is rotated in the opposite direction to re-insert the positioning rod into the positioning hole of the connecting block 131, fixing the connecting block 131 and the connecting groove 132, thus completing the installation of the new rivet gun head 12.
