Description

Technical Field

[0001] This utility model relates to the field of riveting technology, and more specifically, to a fixing structure for preventing studs from falling off due to riveting vibration. Background Technology

[0002] In the field of mechanical assembly and product processing, stud riveting is a common process for connecting components, especially suitable for scenarios where studs are needed for subsequent fastening or support. When the processing condition is "stud riveting height is less than product plate thickness", the industry generally uses a punch press as the riveting equipment to complete the initial assembly of the stud and the product using the pressure of the punch press.

[0003] During the operation of the punch press, continuous and strong vibrations are generated. These vibrations directly affect the mating parts between the stud and the product mounting hole in the initial assembly. However, since the stud riveting height is less than the plate thickness, the stud's support length in the product hole is limited. Therefore, the vibrations can easily disrupt the initial mating state between the stud and the product hole, causing the stud to fall out of the product hole. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides a fixing structure to prevent studs from falling off due to riveting vibration, aiming to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a fixing structure to prevent studs from falling off due to riveting vibration, comprising a steel plate and a stud, wherein the stud is located on the top of the steel plate, the steel plate has multiple mounting holes, and the bottom end of the stud passes through one of the mounting holes, the stud is provided with a connecting assembly, the connecting assembly includes a pressure plate, a vertical cylinder, four threaded clamps, four handles, a connecting ring, a limiting ring, four fixing bolts and two elastic washers, the pressure plate, the vertical cylinder and the connecting ring are all movably disposed on the outside of the stud, and the top and bottom ends of the vertical cylinder are fixedly connected to the pressure plate and the connecting ring respectively.

[0006] Furthermore, the vertical cylinder is provided with multiple threaded holes, and one end of each of the four threaded clamps extends into one of the four threaded holes.

[0007] As can be seen, in the above technical solution, inserting the threaded clamp into different threaded holes can adjust the position of the elastic top block on the steel plate.

[0008] Furthermore, one end of the threaded rod is fixedly connected to an elastic top block, and the other end of the elastic top block is in contact with the outer side of the stud.

[0009] As can be seen, in the above technical solution, by setting an elastic top block, the elastic top block can tightly abut against the stud due to its own elasticity, thereby forming a stable snap-fit.

[0010] Furthermore, all four handles are located on the outside of the vertical cylinder, and one end of each of the four handles is fixedly connected to a plurality of threaded rods.

[0011] As can be seen, in the above technical solution, a handle is provided to facilitate the rotation of the threaded clamp.

[0012] Furthermore, the limiting ring is movably sleeved on the connecting ring, and the limiting ring and the connecting ring are fixed together by four fixing bolts.

[0013] As can be seen, in the above technical solution, fixing bolts are used to facilitate the installation and disassembly of the connecting ring.

[0014] Furthermore, the opposite sides of the two elastic washers are fixedly connected to the pressure plate and the limiting ring, respectively, and the opposite sides of the two elastic washers are in contact with the steel plate.

[0015] As can be seen, in the above technical solution, the two elastic washers can improve the stability between the pressure plate and the limiting ring and the steel plate.

[0016] Furthermore, four insert rods are fixedly connected to the top of the limiting ring, and multiple insertion holes are opened at the bottom of the steel plate, with the tops of the four insert rods extending into four of the insertion holes respectively.

[0017] As can be seen, in the above technical solution, the four holes and four rods work together to position the limiting ring.

[0018] The technical effects and advantages of this utility model are as follows: 1. This utility model involves placing a pressure plate on top of a steel plate, inserting the bottom end of the vertical cylinder into the mounting hole, then placing a limiting ring on the connecting ring, rotating four fixing bolts in sequence to fix the connecting ring and the limiting ring, and finally inserting the stud into the vertical cylinder. The stud is then secured by four threaded clamps and four elastic top blocks. The operation is simple, effectively improving the stability between the stud and the steel plate, and preventing the stud from falling off due to riveting vibration. 2. This utility model uses a handle to rotate, which drives the threaded clamp rod to move horizontally, thereby driving the elastic top block to move horizontally. The position of the elastic top block in the steel plate can be adjusted as needed. The handle is reversed so that the threaded clamp rod is away from the threaded hole. Then the threaded clamp rod is inserted into another threaded hole. The position of the elastic top block in the steel plate can be adjusted as needed, so that different studs can be clamped. The structure is simple and the application range is wide. Attached Figure Description

[0022] The following specific embodiments illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0023] Refer to the instruction manual appendix Figure 1-5The fixing structure for preventing studs from falling off due to riveting vibration in this embodiment includes a steel plate 1 and a stud 2, with the stud 2 located on top of the steel plate 1. The steel plate 1 has multiple mounting holes 3, and the bottom end of the stud 2 passes through one of the mounting holes 3. A connecting assembly 4 is provided on the stud 2. The connecting assembly 4 includes a pressure plate 401, a vertical cylinder 402, four threaded rods 403, four handles 404, a connecting ring 406, a limiting ring 407, four fixing bolts 408, and two elastic washers 409. The pressure plate 401, the vertical cylinder 402, and the connecting ring 406 are all movably disposed on the outside of the stud 2. The top and bottom ends of the vertical cylinder 402 are fixedly connected to the pressure plate 401 and the connecting ring 406, respectively.

[0024] like Figure 3-5 As shown, the vertical cylinder 402 has multiple threaded holes 405, and one end of each of the four threaded rods 403 extends into one of the four threaded holes 405. One end of each threaded rod 403 is fixedly connected to an elastic top block 410, and the other end of the elastic top block 410 contacts the outer side of the stud 2. All four handles 404 are located on the outer side of the vertical cylinder 402, and one end of each handle 404 is fixedly connected to the multiple threaded rods 403.

[0025] Rotating the handle 404 causes the threaded locking rod 403 to move horizontally, which in turn causes the elastic top block 410 to move horizontally. The position of the elastic top block 410 in the steel plate 1 can be adjusted as needed. Similarly, the positions of the other three elastic top blocks 410 can be adjusted. Reversing the handle 404 makes the threaded locking rod 403 move away from the threaded hole 405. Then, the threaded locking rod 403 is inserted into another threaded hole 405. The position of the elastic top block 410 on the steel plate 1 can be adjusted as needed. Similarly, the positions of the other three elastic top blocks 410 can be adjusted, thus enabling the locking of different studs 2. The structure is simple and has a wide range of applications.

[0026] like Figure 3-4 As shown, the limiting ring 407 is movably sleeved on the connecting ring 406, and the limiting ring 407 and the connecting ring 406 are fixed together by four fixing bolts 408. The opposite sides of the two elastic washers 409 are fixedly connected to the pressure plate 401 and the limiting ring 407 respectively, and the opposite sides of the two elastic washers 409 are in contact with the steel plate 1.

[0027] like Figure 2-3 As shown, four insertion rods 6 are fixedly connected to the top of the limiting ring 407, and multiple insertion holes 5 are opened at the bottom of the steel plate 1, with the tops of the four insertion rods 6 extending into four of the insertion holes 5 respectively.

[0028] The usage method of this embodiment is as follows: In use, multiple mounting holes 3 are made on the steel plate 1. Then, the pressure plate 401 is placed on top of the steel plate 1, and the bottom end of the vertical cylinder 402 is inserted into the mounting hole 3. The limiting ring 407 is then fitted onto the connecting ring 406, and the four insert rods 6 are respectively inserted into the four insert holes 5, thereby positioning the limiting ring 407. The four fixing bolts 408 are rotated in sequence to fix the connecting ring 406 and the limiting ring 407. The two elastic washers 409 can prevent the pressure plate 401 and the limiting ring 407 from contacting the steel plate 1. Rigid contact improves the stability between the pressure plate 401 and the limiting ring 407 and the steel plate 1. Finally, the stud 2 is inserted into the vertical cylinder 402 and secured by four threaded rods 403 and four elastic top blocks 410. Similarly, multiple connecting components 4 are installed, which can secure multiple studs 2. The operation is simple and effectively improves the stability between the stud 2 and the steel plate 1, preventing the stud 2 from falling off due to riveting vibration. It is worth noting that the elastic top block 410 is conical in shape.
