Description

Technical Field

[0001] This utility model relates to the field of metal processing technology, specifically to a metal sheet riveting device. Background Technology

[0002] In the joining process of metal sheets, riveting is a commonly used method. The working principle of riveting equipment is mainly to use the pressure generated by the power system to drive the rivet head in the riveting mechanism to apply axial pressure to the rivet, causing the tail of the rivet to undergo plastic deformation, thereby forming a strong riveted joint and tightly fixing the connected parts together. During the riveting process, factors such as the shape and size of the rivet head, the riveting pressure, the riveting speed, and the materials of the rivet and the connected parts will affect the riveting quality.

[0003] Current sheet metal riveting equipment suffers from insufficient precision in controlling the riveting position. In actual operation, it is difficult to determine the contact point between the rivet and the sheet metal, leading to deviations that affect the connection strength of the product, increase the defect rate, and reduce production efficiency. Therefore, we propose a sheet metal riveting device. Utility Model Content

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-4 A metal sheet riveting device includes a base 1, a vertical plate 2 fixedly connected to the base 1, a control center 3 fixedly connected to the inner side of the vertical plate 2, a top plate 4 fixedly connected to the top of the vertical plate 2, and a riveting mechanism 5 provided above the top plate 4.

[0022] The riveting mechanism 5 includes a moving device and a riveting device. The moving device drives the riveting device to rivet the metal plate 7.

[0023] Furthermore, the moving device includes a limiting groove 501, with two sets of limiting grooves 501 formed on the upper surface of the top plate 4. A limiting block 502 is slidably connected to the inner side of the limiting groove 501, and a moving block 503 is fixedly connected above the limiting block 502. A first threaded rod 504 is threadedly connected to the inner side of the moving block 503, and a drive motor 505 is fixedly connected to one end of the first threaded rod 504. Two first limiting rods 506 pass through the inner side of the moving block 503, and baffles 507 are fixedly connected to both ends of the first limiting rods 506. Through the configuration of the moving device, when in use, starting the drive motor 505 drives the first limiting rod 506... When the first threaded rod 504 rotates, according to the principle of threaded transmission, the moving block 503, which is threadedly connected to the first threaded rod 504, moves along the axial direction of the first threaded rod 504, thereby driving the moving block 503 to move. At the same time, the limiting block 502 slides inside the limiting groove 501, and the limiting groove 501 limits the limiting block 502, making the sliding of the moving block 503 more stable. The first limiting rod 506 passes through the moving block 503, further restricting the moving block 503 and preventing the moving block 503 from deviating in the left, right or up and down directions during the movement, thus improving the accuracy of the movement.

[0024] Furthermore, the riveting device includes a connecting block 508, which is fixed to the lower surface of the moving block 503. A hydraulic cylinder 509 is fixedly connected to the lower part of the connecting block 508, and a riveting plate 510 is fixedly connected to the lower part of the hydraulic cylinder 509. A riveting head 511 is fixedly connected to the lower part of the riveting plate 510. With the setting of the riveting device, since the connecting block 508 is fixed to the lower surface of the moving block 503, the moving block 503 can drive the connecting block 508 to move simultaneously. The hydraulic cylinder 509 is activated, pushing the riveting plate 510 and the riveting head 511 to move downward. The riveting head 511 applies pressure to the metal plate 7 below, thereby realizing the riveting operation. Through the cooperation of the moving device and the riveting device, the contact point between the rivet and the plate can be precisely controlled, making it less prone to deviation, increasing the connection strength of the product, reducing the defect rate, and increasing production efficiency.

[0025] Furthermore, the inner dimensions of the limiting groove 501 and the outer dimensions of the limiting block 502 are matched. The first threaded rod 504 is rotatably connected to the baffle 507, and the baffle 507 is fixed on the upper surface of the top plate 4. With the setting of the limiting groove 501 and the limiting block 502, the limiting block 502 slides inside the limiting groove 501 during use. The limiting groove 501 limits the limiting block 502, making the sliding of the moving block 503 more stable.

[0026] Furthermore, it also includes a fixing mechanism 6, which includes a fixing plate 601 fixedly connected to the surface of the base 1. A second threaded rod 602 is rotatably connected to the inner side of the fixing plate 601. A servo motor 603 is fixedly connected to one end of the second threaded rod 602, and a stop block 604 is fixedly connected to the other end of the second threaded rod 602. A push plate 605 is threadedly connected to the outer side of the second threaded rod 602. A pad 606 is provided on the outer side of the push plate 605. A second limiting rod 607 passes through one side surface of the push plate 605. A base plate 608 is fixedly connected to the top of the base 1. Multiple fixing holes 609 are opened on the top of the base plate 608. Fixing pins 610 are engaged inside the fixing holes 609. A positioning plate 611 is fixedly connected above the fixing pins 610. A metal plate 7 is placed on the top of the base plate 608. Through the setting of the fixing mechanism 6, when in use, the fixing pins 610 are inserted into the fixing holes 609. In the process, a positioning plate 611 is fixedly connected above the metal plate 7. When placing the metal plate 7, the edge of the metal plate 7 can be aligned with the positioning plate 611, thereby positioning the metal plate 7 in the planar direction. The design of multiple fixing holes 609 and fixing pins 610 can flexibly adjust the positioning position according to the size and shape of the metal plate 7, ensuring the positional accuracy of the metal plate 7 during the processing. Then, the servo motor 603 is started, driving the second threaded rod 602 to rotate. According to the principle of thread transmission, the push plate 605, which is threadedly connected to the second threaded rod 602, will move along the axial direction of the second threaded rod 602. The pad 606 can increase the contact area with the metal plate 7 and reduce the pressure. When the servo motor 603 drives the second threaded rod 602 to rotate and causes the push plate 605 to move towards the metal plate 7, the push plate 605 and the pad 606 cooperate to apply a lateral clamping force to the metal plate 7, fixing the metal plate 7 and improving the accuracy of riveting.

[0027] Furthermore, the stop 604 is provided with two sets, and the two ends of the second limiting rod 607 are fixed to the fixed plate 601 and the stop 604 respectively. With the setting of the second limiting rod 607, the second limiting rod 607 can limit the push plate 605 during use, so that the movement of the push plate 605 is more stable.

[0028] Furthermore, a pad 606 is also provided on the surface of the positioning plate 611. The inner dimension of the fixing hole 609 matches the outer dimension of the fixing pin 610. With the pad 606 provided, the pad 606 can increase the contact area with the metal plate 7 and reduce the pressure during use, preventing secondary damage to the metal plate 7 during riveting.

[0029] Working principle: The fixing pin 610 is inserted into the fixing hole 609, and a positioning plate 611 is fixedly connected above it. When placing the metal plate 7, the edge of the metal plate 7 can be aligned with the positioning plate 611, thereby positioning the metal plate 7 in the planar direction. The design of multiple fixing holes 609 and fixing pins 610 can flexibly adjust the positioning position according to the size and shape of the metal plate 7, ensuring the positional accuracy of the metal plate 7 during processing. Then, the servo motor 603 is started, driving the second threaded rod 602 to rotate. Based on the principle of threaded transmission... The push plate 605, threadedly connected to the second threaded rod 602, moves axially along the second threaded rod 602. The second limiting rod 607 can limit the movement of the push plate 605, making its movement more stable. The pad 606 increases the contact area with the metal plate 7 and reduces the pressure, preventing secondary damage to the metal plate 7 during riveting. When the servo motor 603 drives the second threaded rod 602 to rotate, causing the push plate 605 to move towards the metal plate 7, the push plate 605 and the pad 606 work together to apply a lateral clamping force to the metal plate 7. The metal plate 7 is fixed, improving the accuracy of riveting. Then, the drive motor 505 is started, driving the first threaded rod 504 to rotate. According to the principle of thread transmission, when the first threaded rod 504 rotates, the moving block 503, which is threadedly connected to the first threaded rod 504, moves along the axial direction of the first threaded rod 504, thereby driving the moving block 503 to move. At the same time, the limiting block 502 slides inside the limiting groove 501. The limiting groove 501 limits the limiting block 502, making the sliding of the moving block 503 more stable. The first limiting rod 506... The moving block 503 is further restricted to prevent it from shifting left or right or up or down during movement, thus improving the accuracy of movement. Then, the hydraulic cylinder 509 is activated to push the riveting plate 510 and the riveting head 511 downward. The riveting head 511 applies pressure to the metal plate 7 below, thereby realizing the riveting operation. Through the cooperation of the moving device and the riveting device, the contact point between the rivet and the plate can be precisely controlled, making it less prone to deviation, increasing the connection strength of the product, reducing the defect rate, and increasing production efficiency.
