Description

Technical Field

[0001] This application relates to the field of grooved rivets, and more particularly to a spin-formed grooved rivet. Background Technology

[0002] Grooved rivets are a special type of rivet made of high-quality carbon steel. Due to their ease of use, high installation efficiency, low noise, and good vibration resistance, grooved rivets are widely used in vehicles, ships, aviation, special machinery, and building installation. At the same time, due to their high shear strength, grooved rivets are also widely used in vehicle manufacturing.

[0003] During the installation of grooved rivets, the operator needs to adjust the pressure regulating valve of the grooved rivet gun used to install the rivets to the high-pressure position in order to achieve riveting. Due to the development of lightweight automobiles, the materials of the riveted workpieces are gradually changing. Some parts of automobiles use thin aluminum plates, which cannot withstand excessive impact. When using the grooved rivet gun, it will generate a strong impact force on the workpiece being installed, which may directly damage the relevant parts in severe cases. Summary of the Invention

[0004] To protect the workpiece, this application provides a spun ring groove rivet.

[0005] The spin-formed grooved rivet provided in this application adopts the following technical solution: A spin-formed grooved rivet includes a rivet core, a rivet head, a locking ring, and a limiting block. The rivet core includes a locking post, a connecting post, and a fixing post. One end of the connecting post is coaxially and fixedly connected to the locking post, and the other end of the connecting post is coaxially and fixedly connected to the fixing post. The outer wall of the connecting post is coaxially provided with a fracture groove. The rivet head is fixedly connected to the end of the locking post opposite to the fixing post. The locking ring is sleeved on the outer circumference of the fixing post and slides along the axial direction of the fixing post. The inner wall of the locking ring is provided with a sliding groove. The outer wall of the locking post is coaxially provided with a limiting groove. One end of the limiting block is slidably connected to the groove wall of the sliding groove, and the other end of the limiting block is used to embed into the limiting groove.

[0006] By adopting the above technical solution, the locking ring is sleeved on the fixed post, and the ring groove rivet gun makes the fixed post slide axially, while pushing the locking ring closer to the rivet head. When the locking ring and the rivet head clamp the workpiece, the limiting block is embedded in the limiting groove, thereby realizing the locking of the locking ring and the locking post. The operation is simple. The ring groove rivet gun applies force to the locking ring and the rivet core, so the workpiece is not easily damaged and the workpiece is protected.

[0007] Preferably, the spun ring groove rivet further includes an abutment plate and a first spring. The abutment plate is connected to the groove wall of the slide, one end of the first spring is fixedly connected to the end of the abutment plate away from the bottom of the slide, and the other end of the first spring is fixedly connected to a limiting block.

[0008] By adopting the above technical solution, the first spring causes the limiting block to press against the limiting groove, and the limiting block is stably embedded in the limiting groove, so that the locking pin and the locking ring are stably locked. The structure is simple and easy to fix the workpiece.

[0009] Preferably, the end of the limiting block facing the nail head is provided with a guide surface, and the distance from the guide surface to the nail head increases as it moves away from the first spring.

[0010] By adopting the above technical solution, when the locking ring slides towards the nail head, the guide surface causes the limiting block to slide in the groove, avoiding the outer wall of the locking column. When the limiting block moves to the position of the limiting groove, the limiting block is embedded in the limiting groove for fixation, which facilitates the embedding of the limiting block into the limiting groove and improves the installation efficiency of the ring groove rivet.

[0011] Preferably, there are multiple limiting grooves, and the multiple limiting grooves are evenly spaced along the axial direction of the locking column.

[0012] By adopting the above technical solution, multiple limiting grooves facilitate the fixing of workpieces of different thicknesses, improve the applicability of ring groove rivets, and increase the utilization rate of ring groove rivets.

[0013] Preferably, there are multiple slide grooves, and the multiple slide grooves are spaced apart along the axial direction of the locking ring.

[0014] By adopting the above technical solution, when the locking ring and the rivet head clamp the workpiece, if a certain limiting block is located between two limiting grooves and cannot complete the locking, other limiting blocks can be embedded in a certain limiting groove to complete the locking of the locking ring and the rivet core, thereby improving the stability of the ring groove rivet.

[0015] Preferably, there are multiple sliding grooves, which are evenly spaced around the axis of the locking ring, and there are multiple limiting blocks, which are arranged in a one-to-one correspondence with the sliding grooves.

[0016] By adopting the above technical solution, multiple limiting blocks are embedded in the limiting groove, so that the multiple limiting blocks are evenly stressed, the limiting blocks are not easily damaged, the service life of the ring groove rivet is extended, and the locking ring is not easy to detach from the locking post.

[0017] Preferably, the spun ring groove rivet further includes a warning rod, a second spring, and a connecting block. The outer wall of the locking ring is provided with a through groove, which communicates with a sliding groove. The groove wall of the through groove is provided with a fixing groove. The warning rod is slidably connected to the groove wall of the through groove. The outer wall of the warning rod is connected to a fixing block, which slides in the fixing groove. One end of the second spring is fixedly connected to the groove wall of the fixing groove, and the other end of the second spring is fixedly connected to the fixing block. One end of the connecting block is fixedly connected to the end of the limiting block facing the warning rod. The end of the warning rod facing the limiting block is provided with a pushing surface, and the other end of the connecting block abuts against the pushing surface.

[0018] By adopting the above technical solution, the sliding of the limiting block drives the sliding of the connecting block, and the sliding of the connecting block drives the sliding of the warning rod. The sliding of the warning rod is used to remind the operator whether the locking ring and the locking pin are locked, making it easier to judge the status of the ring groove rivet, making it easier to use and improving installation efficiency.

[0019] Preferably, the spun grooved rivet further includes an abutment post and a stop block. The locking ring has an anti-disengagement groove at one end facing the rivet head, the anti-disengagement groove is connected to the sliding groove, the abutment post is slidably connected to the groove wall of the anti-disengagement groove, the stop block is fixedly connected to the groove wall of the sliding groove, the abutment plate abuts against the end of the stop block facing the axis of the locking ring, the abutment post is located on the side of the abutment plate away from the axis of the locking ring, the abutment post has an abutment surface at one end facing the abutment plate, and the distance from the abutment surface to the axis of the locking ring increases as it moves away from the rivet head.

[0020] By adopting the above technical solution, when the locking ring abuts against the surface of the workpiece, the abutting post slides towards the limiting block, and the abutting surface causes the abutting plate to move towards the axis of the locking ring, thereby enhancing the elastic force of the first spring, making the locking force between the locking ring and the locking post stronger, and making the connection strength of the ring groove rivet higher.

[0021] Preferably, the groove opening of the anti-detachment groove is coaxially fixedly connected with a retaining ring, and the abutment post includes a sliding post and a pushing post. The pushing post is fixedly connected to one end of the sliding post, the pushing post slides within the retaining ring, and the sliding post is slidably connected to the groove wall of the anti-detachment groove.

[0022] By adopting the above technical solution, the retaining ring makes it difficult for the sliding post to fall out of the anti-detachment groove, reducing the probability of the sliding post being lost and facilitating the use of the ring groove rivet.

[0023] Preferably, the inner diameter of the locking ring is smaller than the diameter of the locking post, and the inner diameter of the locking ring is larger than the diameter of the fixing post.

[0024] By adopting the above technical solution, the locking ring and locking pin are tightened, which improves the connection strength between the locking ring and locking pin and makes it easier to firmly fix the ring groove rivet to the workpiece.

[0025] In summary, this application includes at least one of the following beneficial technical effects: 1. The locking ring is sleeved on the fixed post. The ring groove rivet gun makes the fixed post slide axially and pushes the locking ring closer to the rivet head. When the locking ring and the rivet head clamp the workpiece, the limiting block is embedded in the limiting groove to lock the locking ring and the locking post. The operation is simple. The ring groove rivet gun applies force to the locking ring and the rivet core, so the workpiece is not easily damaged and the workpiece is protected. 2. The sliding of the limit block drives the sliding of the connecting block, and the sliding of the connecting block drives the sliding of the warning rod. The sliding of the warning rod is used to remind the operator whether the locking ring and the locking pin are locked, making it easier to judge the status of the ring groove rivet, making it easier to use and improving installation efficiency; 3. When the locking ring abuts against the workpiece surface, the abutting post slides towards the limiting block, and the abutting surface causes the abutting plate to move towards the locking ring axis, enhancing the elastic force of the first spring, making the locking force between the locking ring and the locking post stronger, and making the connection strength of the ring groove rivet higher.

[0033] The following is in conjunction with the appendix Figure 1-6 This application will be described in further detail.

[0034] This application discloses a spun ring groove rivet. (Refer to...) Figure 1 and Figure 2 The spin-formed grooved rivet includes a rivet core 1, a rivet head 2, a locking ring 3, a locking assembly 4, a warning assembly 5, and a clamping assembly 6.

[0035] Reference Figure 3 The nail core 1 includes a locking post 11, a connecting post 12, and a fixing post 13. One end of the connecting post 12 is coaxially fixedly connected to one end of the locking post 11, and the other end of the connecting post 12 is coaxially fixedly connected to one end of the fixing post 13.

[0037] Reference Figure 2 The inner wall of the locking opening 31 is provided with a sliding groove 311. The length direction of the sliding groove 311 is along the radial direction of the locking opening 31. There are four sliding grooves 311. The four sliding grooves 311 are evenly divided into two groups. The two groups of sliding grooves 311 are spaced apart along the axial direction of the locking opening 31. The two sliding grooves 311 in each group are evenly spaced around the axial direction of the locking opening 31. The four sliding grooves 311 are evenly spaced around the axial direction of the locking opening 31.

[0038] Reference Figure 4There are four locking components 4, which are arranged one-to-one with the slide grooves 311. Each locking component 4 includes a stop block 41, an abutment plate 42, a first spring 43, and a limiting block 44. The stop block 41 is fixedly connected to the groove wall of the slide groove 311. There are two stop blocks 41, which are located on opposite groove walls of the slide groove 311. The abutment plate 42 abuts against the end of the stop block 41 that is away from the bottom of the slide groove 311. A pressing block 421 is connected to the end of the abutment plate 42 facing the bottom of the slide groove 311. The outer wall of the pressing block 421 is slidably connected to the end of the stop block 41 facing the other stop block 41. There is a certain distance between the pressing block 421 and the bottom of the slide groove 311.

The distance from the guide surface 441 to the nail head 2 increases as it moves away from the first spring 43.

[0040] Reference Figure 4 There are four warning components 5, each corresponding to a locking component 4. Each warning component 5 includes a warning rod 51, a second spring 52, and a connecting block 53. The outer wall of the locking ring 3 has a through groove 32, which connects to a sliding groove 311. The length direction of the through groove 32 is perpendicular to the length direction of the sliding groove 311. A fixing groove 321 is provided on the groove wall of the through groove 32 away from the axis of the locking opening 31. The warning rod 51 is slidably connected to the groove wall of the through groove 32. A fixing block 511 is fixedly connected to the outer wall of the warning rod 51. 511 is slidably connected to the wall of the fixed groove 321. One end of the second spring 52 is fixedly connected to the wall of the fixed groove 321 facing the slide groove 311. The other end of the second spring 52 is fixedly connected to the fixed block 511. One end of the connecting block 53 is fixedly connected to the end of the limiting block 44 facing the warning rod 51. The end of the warning rod 51 facing the limiting block 44 is provided with a pushing surface 512. The other end of the connecting block 53 abuts against the pushing surface 512. The distance from the pushing surface 512 to the slide groove 311 decreases as it moves away from the fixed block 511.

[0041] Reference Figure 3 and Figure 4When the limiting block 44 moves toward the bottom of the slide groove 311, the connecting block 53 slides synchronously. The connecting block 53 abuts against the pushing surface 512, causing the warning rod 51 to move away from the slide groove 311. The second spring 52 contracts, and the warning rod 51 extends out of the through groove 32, indicating that the limiting block 44 is not embedded in the limiting groove 111 in the current state. When the limiting block 44 is embedded in the limiting groove 111, the limiting block 44 slides toward the axis of the locking port 31, and the connecting block 53 slides synchronously. The second spring 52 pushes the warning rod 51 to reset, reminding the operator that the locking has been completed.

[0042] Reference Figure 5 and Figure 6 There are four clamping components 6, and each clamping component 6 is set in a one-to-one correspondence with the locking component 4. The clamping component 6 includes an abutment post 61. The locking ring 3 has an anti-disengagement groove 33 at one end facing the nail head 2. The anti-disengagement groove 33 is connected to the slide groove 311. The length direction of the anti-disengagement groove 33 is perpendicular to the length direction of the slide groove 311. The groove opening of the anti-disengagement groove 33 is coaxially fixedly connected to a retaining ring 331.

[0043] The abutment post 61 includes a sliding post 611 and a pushing post 612. The pushing post 612 is fixedly connected to one end of the sliding post 611. The outer wall of the sliding post 611 is slidably connected to the groove wall of the anti-disengagement groove 33. The outer wall of the pushing post 612 is slidably connected to the inner wall of the retaining ring 331. The end of the sliding post 611 facing the pressing block 421 is provided with an abutment surface 6111. The distance from the abutment surface 6111 to the axis of the locking ring 3 increases as it moves away from the nail head 2. The end of the sliding post 611 away from the pushing post 612 extends into the groove bottom between the pressing block 421 and the sliding groove 311.

[0044] When the locking ring 3 abuts against the workpiece, the pushing column 612 slides towards the slide groove 311, and the lower end of the pressing block 421 abuts against the abutting surface 6111, so that the sliding column 611 slides while pushing the pressing block 421 to slide, and the first spring 43 further contracts, enhancing the locking force between the locking ring 3 and the locking column 11.

[0045] The implementation principle of a spin-formed grooved rivet in this application embodiment is as follows: the rivet core 1 is inserted into the hole of the workpiece, the locking ring 3 is sleeved on the fixing post 13, the internal components of the grooved rivet rotate, causing the fixing post 13 to slide axially, pushing the locking ring 3 to move towards the rivet head 2. As the locking ring 3 slides, the limiting block 44 slides in the sliding groove 311, and the limiting block 44 is continuously embedded in the limiting groove 111. The warning rod 51 slides back and forth to remind the operator of the status of the limiting block 44, until the locking ring 3 abuts against the workpiece, and the abutting post 61 slides to make the limiting block 44 abut against the limiting groove 111.

[0046] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
