Traditional riveting operation mostly relies on manual operation, and workers need to hold rivet gun and accurately place rivets at the riveting position according to experience. This method has many disadvantages. With the development of automation technology, automatic drilling and riveting system emerges as the times require.

[0003] The utility model discloses a rivet positioning mechanism for robot automatic drilling and riveting system, including telescopic cylinder, the side fixed connection of telescopic cylinder has fixed block no.

[0004] However, the device involved in the above patent has obvious shortcomings in actual application. Generally speaking, a special driving mechanism is needed to drive the whole device to move downward, so that the rivet machine cooperates with the rivet to approach the workpiece to be processed, and then the telescopic cylinder drives the rivet machine to further press down and work. However, in this process, when the device moves downward as a whole, the positioning block will be dislocated with the feeding mechanism, the opening of the limiting groove loses external limiting, which easily leads to the accidental falling of the rivet from the opening, and the risk of processing failure increases significantly. Once this situation occurs, manual intervention is often needed to verify the processing effect, and when facing large workpiece processing tasks, comprehensive and detailed verification will undoubtedly consume a lot of time and energy, greatly affecting production efficiency and increasing production cost.

[0019] The mounting plate 5 is provided with feed hole 501 corresponding to the limiting groove 901.

[0020] The top of the mounting plate 5 is vertically fixedly connected with feed pipe 13 opposite the feed hole 501.

[0021] The positioning plate 9 and the rotating baffle 10 are located in the same plane.

[0022] The counterweight 12 is located on the end close to the connecting plate 7 of the rotating shaft 8, the connecting plate 7 is provided with two vertical plates 14, and the two vertical plates 14 are respectively located above the two rotating shafts 8.

[0023] Working principle:

[0024] In the initial state, the electric telescopic rod 6 is in the retracted state, and the parts on the connecting plate 7 are maintained in a position. The two positioning plates 9 are relatively static under the cooperation of the counterweight 12, the limiting baffle 11 and the rotating baffle 10, the limiting groove 901 at the top of the two positioning plates 9 is open upward, and the feeding hole 501 corresponds to the limiting groove 901. At this time, the feeding mechanism can accurately deliver the rivet into the limiting groove 901 through the feeding pipe 13 on the mounting plate 5 and the feeding hole 501, and since the feeding pipe 13 plays a guiding role, it ensures that the rivet smoothly enters the limiting groove 901 and is stably clamped.

[0025] When the riveting operation is needed, the telescopic cylinder 2 drives the mounting seat 3 and the riveting machine 4 at the bottom to move downward, at the same time, the electric telescopic rod 6 starts to stretch and pushes the connecting plate 7 to move horizontally. In this process, only the top of the rivet is not limited, so as to avoid the situation of falling during the movement. With the overall downward movement of the device, the two positioning plates 9, the rivet thereon and the riveting machine 4 approach the workpiece to be processed.

[0026] After reaching the riveting position, the riveting machine 4 continues to press down to perform the riveting operation on the rivet, at this time, the positioning plate 9 is turned downward under the pressure of the riveting machine 4, thereby removing the limiting shielding of the rivet, so that the rivet is butt-jointed to the workpiece to be processed, and after the riveting is completed, the telescopic cylinder 2 drives the riveting machine 4 to reset, the electric telescopic rod 6 drives the connecting plate 7 to reset, and the positioning plate 9 is reversely turned to reset under the influence of the gravity of the counterweight 12. During the whole movement process, the counterweight 12 always tends to maintain the original state of the rotating baffle 10 and the positioning plate 9 by using its own gravity, and the limiting baffle 11 limits the excessive rotation of the rotating baffle 10 from above, so that the positioning plate 9 will not be accidentally turned under the external force interference of the riveting machine 4, so that the rivet is always accurately and stably clamped in the limiting groove 901. When the positioning plate 9 is turned downward under the pressure of the riveting machine 4, the vertical plate 14 limits the counterweight 12, so as to avoid the excessive rotation of the counterweight 12 during the rotation of the rotating shaft 8, avoid the rotation of the rotating shaft 8 and each part thereon exceeding 180 degrees, so that when the riveting machine 4 rises to reset, the rotating shaft 8 and the positioning plate 9 can reset under the gravity of the counterweight 12, so as to ensure that the riveting process is smoothly and efficiently completed, and the reliability and processing precision of the automatic drilling and riveting system are effectively improved.

[0027] The utility model effectively prevents the rivet from falling from the limiting groove 901, greatly reduces the risk of processing failure, and improves the reliability of the automatic drilling and riveting system.
