[0002] In modern industrial production, riveting is a commonly used connection method, which uses rivets to connect two or more rivet parts together in a non-detachable connection. At present, most manufacturing industries have achieved automated production. During the riveting process, most of the existing rivet feeders can only load one type of material when working. When different types of rivets need to be automatically loaded, it is necessary to replace the corresponding loading track according to the different types of rivets. This operation is very inconvenient and wastes time.

[0003] In view of the above problems, the inventor proposes an automatic rivet feeding device to solve the above problems. Utility Model Content

[0010] 1. By setting a double-headed threaded rod, two pulleys and a transmission belt are used together to drive the two double-headed threaded rods to rotate at the same time, so that the two slides move to the middle or to both sides. Since the two feeding rails are installed on the two slides, the feeding rails are driven to move to the middle or to both sides at the same time to adjust the distance between the feeding rails, so that different types of rivets can be automatically fed. There is no need to change the feeding rails to directly realize the automatic feeding of different types of rivets, which is convenient to operate and saves time;

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0018] Example: Figure 1-3 As shown, the utility model provides an automatic rivet feeding device, including a base 1, a support plate 11 is provided above the base 1, two groups of symmetrically distributed fixed blocks 12 are fixedly installed on the top of the support plate 11, a double-headed threaded rod 13 is rotatably installed in the middle of each group of fixed blocks 12, the outer parts of the two double-headed threaded rods 13 are commonly threadedly connected to two symmetrically distributed slides 14, the tops of the two slides 14 are fixedly installed with feeding rails 15, the outer part of each double-headed threaded rod 13 is fixedly installed with a pulley 131, and the outer movable sleeve of the pulley 131 is provided with a transmission belt 132.

[0019] By adopting the above technical scheme, when one of the double-headed threaded rods 13 rotates, it drives the two slides 14 to move toward the middle or to both sides. At the same time, the rotation of one of the double-headed threaded rods 13 drives one of the pulleys 131 to rotate, and then drives the transmission belt 132 to rotate. Then, with the rotation of the transmission belt 132, the other pulley 131 is driven to rotate. The cooperation between the two pulleys 131 and the transmission belt 132 drives the other double-headed threaded rod 13 to rotate, so that the two slides 14 are more stable in movement. Then, because the two feeding rails 15 are installed on the two slides 14, as the two slides 14 slide, the corresponding feeding rails 15 are driven to move toward the middle or slide to both sides to adjust the distance between the feeding rails 15, so that different types of rivets can be automatically fed, and different types of rivets can be automatically fed directly without replacing the feeding rails 15, which is convenient to operate and saves time.

[0020] A vibration plate 2 is provided on the upper surface of the base 1. Two symmetrically distributed L-shaped fixing plates 21 are fixedly installed on one side of the vibration plate 2 close to the loading track 15. The bottoms of the two L-shaped fixing plates 21 are both threadedly connected with threaded rods 22, and the external threads of the threaded rods 22 are connected with metal sheets 23.

[0021] By adopting the above technical solution, when the threaded rod 22 rotates, the metal sheet 23 is not clamped on the L-shaped fixing plate 21. At the same time, the threaded rod 22 is separated from the metal sheet 23 and threadedly connected to the L-shaped fixing plate 21, thereby facilitating the replacement of the metal sheet 23.

[0022] A concave fixing seat 17 is fixedly mounted on the top of the support plate 11 and below the two slide plates 14 , and the bottom ends of the two slide plates 14 are in contact with the top ends of the concave fixing seat 17 .

[0023] By adopting the above technical solution, the two slide plates 14 are prevented from rotating along with the rotation of the two double-headed threaded rods 13, and the two slide plates 14 are only allowed to move toward the middle or to both sides.

[0024] Two groups of symmetrically distributed supporting legs 101 are fixedly mounted at the four corners of the bottom end of the supporting plate 11 , and the bottom ends of the supporting legs 101 are fixedly mounted on the top end of the base 1 .

[0025] By adopting the above technical solution, the support plate 11 is supported on the base 1 .

[0026] The bottom ends of the two metal sheets 23 are in contact with the top ends of the corresponding L-shaped fixing plates 21 , and the side of the metal sheet 23 away from the loading track 15 is in contact with the vibration plate 2 .

[0027] A handle 24 is fixedly mounted on the bottom ends of the two threaded rods 22 .

[0028] By adopting the above technical solution, when holding the handle 24, the threaded rod 22 is driven to rotate, so that the metal sheet 23 is no longer clamped on the L-shaped fixing plate 21, so that the metal sheet 23 can be taken out and replaced conveniently.

[0029] A motor 16 is fixedly mounted on one side of the top end of the support plate 11 close to one of the double-threaded rods 13 , and a driving end of the motor 16 is fixedly mounted on the end of one of the double-threaded rods 13 .

[0030] By adopting the above technical solution, when the motor 16 is started, it drives one of the double-headed threaded rods 13 to rotate, thereby driving the two slide plates 14 to slide toward the middle or to both sides to adjust the distance between the two loading rails 15.

[0031] Working principle: When in use, first adjust the distance between the feeding rails 15 according to different types of rivets, so that the distance between the feeding rails 15 is greater than the diameter of the rivet body and smaller than the diameter of the rivet head. For specific operation, control the start of the motor 16 to drive one of the double-headed threaded rods 13 to rotate, and then drive the two slides 14 to move to the middle or to both sides. At the same time, the rotation of one of the double-headed threaded rods 13 drives one of the pulleys 131 to rotate, and then drives the transmission belt 132 to rotate. Then, with the rotation of the transmission belt 132, the other pulley 131 is driven to rotate. The cooperation between the two pulleys 131 and the transmission belt 132 drives the other double-headed threaded rod 13 to rotate, so that the two slides 14 are in The movement is more stable. Then, because the two feeding rails 15 are installed on the two slides 14, as the two slides 14 slide, the corresponding feeding rails 15 are driven to move toward the middle or slide to both sides. By holding the handle 24 and rotating the threaded rod 22, the metal sheet 23 is no longer clamped on the L-shaped fixing plate 21. At the same time, the threaded rod 22 is disengaged from the metal sheet 23 and threadedly connected to the L-shaped fixing plate 21. Then, the metal sheet 23 is replaced so that the distance of the metal sheet 23 is greater than the diameter of the rivet body and smaller than the diameter of the rivet head, which is consistent with the distance between the feeding rails 15. After all adjustments are made, rivets of different types are placed in the vibration plate 2, and then the rivets are automatically fed onto the feeding rails 15 through the vibration of the vibration plate 2.

[0032] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
