Description

Technical Field

[0001] This utility model relates to the field of riveting device technology, and in particular to a high-efficiency riveting device. Background Technology

[0002] Riveting is a process that achieves permanent connection of materials through mechanical deformation. Its core principle is to use the plastic deformation of rivets to fix two or more workpieces together in a non-detachable manner. Nowadays, many companies use riveting technology in their machining and manufacturing processes. Compared with welding, riveting does not require a heat source and can avoid material oxidation, deformation and residual stress. Compared with bolt connection, riveting does not require space for disassembly and is more suitable for scenarios with strict requirements for weight or sealing. However, the traditional riveting operation method that is currently widely used in the industry still relies heavily on manual operation of the product by hand.

[0003] In existing technologies, operators need to manually fix the workpiece to be riveted onto the workbench while applying pressure with a hand-held riveting tool. This results in operators' fingers being pinched by rivets or injured by the high-speed rotating riveting gun, leading to a high risk of accidents. Furthermore, it is difficult to ensure the accuracy of the riveting angle during operation. During continuous operation, rivet misalignment due to operator fatigue or distraction often occurs. Therefore, there is a need to improve the riveting device to solve the above problems. Utility Model Content

[0023] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0024] Please see Figure 1 - Figure 7This utility model provides an embodiment of a high-efficiency riveting device, including a base plate 1, a support frame 21, and an adjustment component. The bottom of the base plate 1 is provided with an adjustment component for adjusting the height of the base plate 1. The top of the base plate 1 is fixedly connected to the support frame 21, and a first hydraulic telescopic rod 22 is fixedly connected to the support frame 21. A nail outlet tube 23 is fixedly connected to the bottom of the first hydraulic telescopic rod 22, and a riveting head 24 is provided inside the nail outlet tube 23. An infrared sensor 25 for improving product riveting is fixedly connected to the support frame 21. The infrared sensor 25 is model E3Z-D61. The working principle of the infrared sensor 25 is a common technical means in this field, so it will not be described in detail. A fixing plate 27 is fixedly connected to the top of the base plate 1, and a riveting base 26 is fixedly connected to the top of the fixing plate 27. A limiting fixture 28 for limiting the product is provided on the top of the fixing plate 27. The device can be adjusted as needed. The product is riveted and replaced using a limiting fixture 28, which restricts the product's movement. The product is placed on the limiting fixture 28, restricting its movement to left and right. The product's pre-set riveting holes are aligned with the riveting base 26. A riveting head 24 is inserted into the riveting holes of the product and the riveting base 26. A first hydraulic telescopic rod 22 applies pressure to the riveting head 24, causing its end or body to expand plastically, forming a mechanical interlock structure. This completes the riveting operation and prevents operators from being injured by rivets or by the high-speed rotating riveting gun. The adjustment component adjusts the height of the base plate 1 by aligning the through holes of the outer frame 31 with the corresponding through holes 36 of the inner rod 35. By fixing the height of the inner rod 35 inside the outer frame 31, the overall height of the device is adjusted for support, improving the device's adaptability.

[0025] Please see Figure 2 - Figure 5In this embodiment, the riveting base 26 has a matching hole at the corresponding position of the riveting head 24. The riveting head 24 is set in the hole of the riveting base 26, making it convenient to rivet the product and improving its convenience. The limiting fixture 28 is provided with an internal hexagon bolt 29, which is threaded into the inside of the fixing plate 27. A washer 210 is provided between the limiting fixture 28 and the internal hexagon bolt 29 to improve the connection stability. The internal hexagon bolt 29 passes through the washer 210. The limiting fixture 28 is used to limit the product and make it easy to replace the product as needed. The product is placed on the limiting fixture 28 to limit the product and make it move only left and right, so that the product can be riveted to the preset position. The riveting base 26 is aligned with the riveting hole, and the riveting head 24 is inserted into the riveting hole of the product and the hole of the riveting base 26. The first hydraulic telescopic rod 22 applies pressure to the riveting head 24, causing its end or body to plastically expand, forming a mechanical interlocking structure, thereby completing the riveting operation. This prevents the operator's fingers from being pinched by the rivet or injured by the high-speed rotating rivet gun parts, reducing the risk factor, improving the riveting accuracy, and enhancing the practicality of the device. The limiting fixture 28 has a matching groove at the corresponding position of the internal hexagon bolt 29. The internal hexagon bolt 29 is placed in the groove of the limiting fixture 28, making it easy to store the internal hexagon bolt 29 and preventing the internal hexagon bolt 29 from protruding from the surface of the limiting fixture 28, thus improving its stability.

[0026] Please see Figure 6 - Figure 7In this embodiment, the adjustment assembly includes an outer frame 31, which is disposed at the bottom of the base plate 1. An inner rod 35 is slidably connected inside the outer frame 31, and the top of the inner rod 35 is fixedly connected to the bottom of the base plate 1. A foot pad 33 is fixedly connected to the bottom of the outer frame 31. A connecting plate 32 is fixedly connected between the outer frames 31, and a second hydraulic telescopic rod 34 is fixedly connected to the top of the connecting plate 32. The top of the second hydraulic telescopic rod 34 is fixedly connected to the bottom of the base plate 1. A through hole 36 is provided on the inner rod 35. An external hexagonal bolt 37 passes through the inner frame 31 and is disposed inside the through hole 36. A nut 38 is threaded onto the outer side of the external hexagonal bolt 37. The adjustment assembly adjusts the height of the base plate 1 by aligning the through hole of the outer frame 31 with the corresponding through hole 36 of the inner rod 35. By fixing the height of the inner rod 35 inside the outer frame 31, the overall height of the device can be adjusted and supported, thus improving the adaptability of the device. The outer frame 31 has a matching groove at the corresponding position of the inner rod 35, and the inner rod 35 slides in the groove of the outer frame 31, thus limiting the inner rod 35 to slide only up and down, thereby improving the convenience of adjusting the height of the device. The outer frame 31 has a matching through hole at the corresponding position of the external hexagonal bolt 37, and the external hexagonal bolt 37 is set inside the through hole of the outer frame 31. There are six sets of through holes 36, which are distributed from top to bottom on the inner rod 35, so that the inner rod 35 can be aligned with the corresponding through hole 36 through the through hole of the outer frame 31, thereby controlling the height of the device and improving the practicality of the device.

[0027] During operation, by unscrewing the nut 38 from the external hex bolt 37, the external hex bolt 37 is pulled out from the through hole 36 and the through hole in the outer frame 31. Then, by activating the second hydraulic telescopic rod 34, the height of the base plate 1 is adjusted. By aligning the through hole of the outer frame 31 with the corresponding through hole 36 of the inner rod 35, the height of the base plate 1 is adjusted, allowing the external hex bolt 37 to be inserted from the through hole 36 and the through hole in the outer frame 31. By screwing the nut 38 onto the outside of the external hex bolt 37, the height of the inner rod 35 inside the outer frame 31 is fixed, thus adjusting the overall height of the device for support and improving its adaptability. The device can be riveted as needed for easy replacement, and the limiting fixture 28, which limits the product's position, is used via the internal hex bolt. 29. This facilitates the installation of the limiting fixture 28 on top of the fixed plate 27. By placing the product on the limiting fixture 28, the product is limited to left and right movement. The product's pre-set riveting holes are aligned with the riveting base 26. The infrared sensor 25 facilitates the alignment of the product's position. After alignment, the controller activates the first hydraulic telescopic rod 22. The first hydraulic telescopic rod 22 drives the riveting head 24 inside the riveting tube 23, inserting it into the riveting holes of the product and the holes of the riveting base 26. The first hydraulic telescopic rod 22 applies pressure to the riveting head 24, causing its end or body to plastically expand, forming a mechanical interlock structure. Then, the first hydraulic telescopic rod 22 retracts, resetting the product and completing the riveting process. After riveting, the product can be removed from the limiting fixture 28. This improves the convenience and stability of product riveting.

[0028] Through the above steps, the product is riveted as needed to facilitate replacement, and the product is limited by the limiting fixture 28. The product is then placed on the limiting fixture 28 to limit its movement, allowing it to move only left and right. The product's pre-set riveting holes are aligned with the riveting base 26. The riveting head 24 is inserted into the riveting holes of the product and the holes of the riveting base 26. The first hydraulic telescopic rod 22 applies pressure to the riveting head 24, causing its end or body to expand plastically, forming a mechanical interlocking structure. This completes the riveting operation and solves the problems of high safety accident risk and easy rivet misalignment.
