Description

Technical Field

[0001] This invention relates to the field of riveting equipment, specifically a riveting device for reinforcing and compensating between plate layers. Background Technology

[0002] In fields such as automotive manufacturing, there are often interlayers with a certain gap between sheet metal parts. To further enhance the effect, these interlayers are typically filled with materials such as sound insulation. However, there are few supporting connection structures between the inner and outer sheet metal parts, and welding reinforcement in the middle of the interlayer is not feasible. Existing riveting equipment has a limited range of riveting structures, which cannot simultaneously rivet the two ends of the riveted parts to the rivet holes on the two sheet metal parts. Furthermore, detaching the riveted structure from the already riveted part is technically difficult, and traditional riveting components are not suitable for reinforcing and compensating interlayer connections. Therefore, this paper proposes an interlayer reinforcement and compensation riveting device to address these issues. Summary of the Invention

[0003] The purpose of this invention is to provide a reinforcement and compensation riveting device between plate layers in order to solve the above-mentioned problems.

[0004] The present invention achieves the above-mentioned objective through the following technical solution: a plate-layer reinforcement and compensation riveting device, comprising a screw tube connected to the output end of a motor, a ring block for extruding outward expansion parts, a push-pull rod, a guide rod and a ring plate placed inside the screw tube. The screw tube has two threaded sections arranged alternately on its surface. Each threaded section has a strip-shaped hole distributed in an annular pattern. The middle part of the threaded section slides in contact with the ring plate. Two ring blocks are threadedly connected to each of the two threaded sections. The two ring blocks in one group act on the extruding outward expansion parts A on the reinforcement and compensation riveting component, and the two ring blocks in the other group act on the extruding outward expansion parts B on the reinforcement and compensation riveting component. Each ring block has a side groove distributed on one side of its ring edge. Each side groove is connected to one end of a riveting block through a rotating shaft fitted with a torsion spring. Each riveting block is adjusted to extend into a corresponding locking hole on the reinforcement and compensation riveting component. Each of the ring blocks is connected to each other by a set of guide rods, and each guide rod slides in contact with the corresponding guide hole on each ring block. The ends of the set of guide rods in the same direction are connected to each other by a connecting ring. The inner ring wall of the ring plate is connected to the push-pull rod by distributed traction strips. One end of the push-pull rod is connected to one end of the screwing tube by a spring.

[0005] Preferably, the ring plate exerts a pushing and rotating force on the contacting rivet block by moving left and right, and the outer diameter of the ring plate is smaller than the outer diameter of the ring block.

[0006] Preferably, the other end of the push-pull rod extends beyond the rectangular hole located on the screw tube.

[0007] Preferably, the reinforcing and compensating rivet is a tubular structure, and the inner diameter of the reinforcing and compensating rivet matches the outer diameter of the ring block.

[0008] Preferably, both the extrusion-expanded portion A and the extrusion-expanded portion B on the reinforcing and compensating rivet are in an outward-expanding state due to extrusion. The middle part of the extrusion-expanded portion A is located in a rivet hole on one of the plates to be riveted, and the middle part of the extrusion-expanded portion B is located in a rivet hole on another plate to be riveted.

[0009] Preferably, the thread structure of the threaded segment is an equal-length reverse thread structure.

[0010] Preferably, the annular surface of the ring plate is provided with arc-shaped holes, and a guide rod passes through the interior of each arc-shaped hole.

[0011] Preferably, the rivet block is in an initial state perpendicular to the side of the ring block.

[0012] The beneficial effects of this invention are: By starting the motor and rotating the connected screw tube, while manually securing the connecting ring, the two rivet blocks in each group can be moved in opposite directions. This facilitates the expansion of the two outward-expanding parts on the reinforcing and compensating rivets, achieving a firm connection between the outward-expanding parts of the reinforcing and compensating rivets and the rivet holes on the plate. This enhances the connection strength between the plate layers, replacing the traditional method of using a large amount of filler material to strengthen the connection strength between the plate layers, and greatly reducing the weight of the plate assembly structure.

[0013] By initially and slightly wedging the beveled end of the contacting rivet block onto the end wall inside the positioning hole, and ensuring that the beveled end of the rivet block does not extend beyond the surface of the reinforcing and compensating rivet, the installation and fixation of the reinforcing and compensating rivet is completed, preventing the reinforcing and compensating rivet from shifting when inserted into the rivet hole located on the plate to be riveted.

[0014] 3. By rapidly pushing and pulling the push rod back and forth, the connected ring plate instantly impacts the rivet block at the end wall that is slightly stuck inside the locking hole, achieving the effect of punching the inclined end of the rivet block out of the locking hole. At this time, the rivet block is in an unreset state, which is conducive to forming a structure that applies inward force to both ends of the outwardly expanding part. Attached Figure Description

They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0021] Please see Figure 1-7As shown, a plate-layer reinforcement and compensation riveting device includes a screw tube 2 connected to the output end of a motor 1, a ring block 3 for pressing outward expansion parts, a push-pull rod 4, a guide rod 5, and a ring plate 6 placed inside the screw tube 2. The screw tube 2 has two threaded sections 230 arranged alternately on its surface. Each threaded section 230 has a strip hole 220 distributed in a ring. The middle part of the threaded section 230 slides in contact with the ring plate 6. Two ring blocks 3 are threadedly connected to each of the two threaded sections 230. The two ring blocks 3 in one group act on the pressing outward expansion parts A on the reinforcement and compensation riveting part 8, and the two ring blocks 3 in the other group act on the pressing outward expansion parts B on the reinforcement and compensation riveting part 8. Each ring block 3 has a side groove distributed on one side of its ring edge. Each side groove is connected to one end of a riveting block 311 through a rotating shaft fitted with a torsion spring. Each riveting block 311 is adjusted to extend into the corresponding locking hole 810 on the reinforcement and compensation riveting part 8. Each of the ring blocks 3 is connected to each other by a set of guide rods 5, and each guide rod 5 slides in contact with the inside of the corresponding guide hole 320 on each of the ring blocks 3. The ends of the set of guide rods 5 in the same direction are connected to each other by a connecting ring 510. The inner ring wall of the ring plate 6 is connected to the push-pull rod 4 by distributed traction strips 410.

[0022] The ring plate 6 moves left and right to exert a pushing and rotating force on the contacting rivet block 311. The outer diameter of the ring plate 6 is smaller than that of the ring block 3. Arc-shaped holes are distributed on the annular surface of the ring plate 6, and a guide rod 5 passes through the interior of each arc-shaped hole. The rivet block 311 is in an initial state that is perpendicular to the side of the ring block 3. The specific plan for this location: See [link / reference] Figure 3 and Figure 7 As shown, taking the leftward movement of the ring plate 6 as an example, the ring plate 6 moves to the left and, combined with the contact between the edge of the ring plate 6 and the inclined surface of one end of the rivet block 311, the ring plate 6 exerts a pushing and lateral rotation force on the contacted rivet block 311, thereby achieving the effect of turning the rivet block 311 from a lateral vertical position to a vertical push, so that the top of the rivet block 311 can pass through the locking hole 810.

[0023] One end of the push-pull rod 4 is connected to one end of the screw tube 2 via a spring 7, and the other end of the push-pull rod 4 extends beyond the rectangular hole 210 located on the screw tube 2; The specific plan for this location: See [link / reference] Figure 2 As shown, when the position of the ring plate 6 connected to the push-pull rod 4 needs to be adjusted, the operator manually pushes or pulls the push-pull rod 4 forward or backward, and the pulling strip 410 connecting the ring plate 6 and the push-pull rod 4 slides through the corresponding strip hole 220, which helps to move and adjust the ring plate 6 at the corresponding threaded section 230.

[0024] The reinforcing and compensating rivet 8 is a tubular structure, and the inner diameter of the reinforcing and compensating rivet 8 matches the outer diameter of the ring block 3. The extrusion outward expansion part A and the extrusion outward expansion part B on the reinforcing and compensating rivet 8 are both in an outward expansion state through extrusion. The middle part of the extrusion outward expansion part A is located in the rivet hole on one of the plates to be riveted 9, and the middle part of the extrusion outward expansion part B is located in the rivet hole on another plate to be riveted 9. The specific plan for this location: See [link / reference] Figure 5 and Figure 6 As shown, when the two rivet blocks 311 in each group move toward each other, the top of the rivet block 311 passes through the locking hole 810, which can compress and deform the outward expansion part A and the outward expansion part B, thereby fixing the two ends of the reinforcing and compensating rivet 8 to the rivet holes on the two plates 9 to be riveted.

[0025] Furthermore, the thread structure of the threaded section 230 is an equal-length reverse thread structure, which is beneficial to keep the two ring blocks 3 threadedly connected at the threaded section 230 in a state of opposing or backward movement when the screw-tightening tube 2 is rotated.

[0026] The riveting operation steps are as follows: Step 1: Combining Figure 1 and Figure 4 As shown, the staff put the reinforcing and compensating rivet 8 onto the two sets of ring blocks 3, and at the same time adjust the locking holes 810 distributed on the reinforcing and compensating rivet 8 to be aligned above the rivet block 311, and hold the reinforcing and compensating rivet 8 still. Combination Figure 1 and Figure 7 As shown, the worker holds the connecting ring 510 still with one hand, and manually rotates the screw tube 2 with the other hand. Using a set of guide rods 5 to restrain the two sets of ring blocks 3 in the direction of rotation, the inclined end of the connected rivet block 311 is moved to the inside of the locking hole 810 directly below one end. As the inclined end of the aforementioned rivet block 311 moves to the inside of the locking hole 810 and the screwing tube 2 is also rotating, the worker quickly pushes and pulls the push-pull rod 4 with hand-eye coordination, causing the ring plate 6 connected by the traction strip 410 to move back and forth rapidly in an instant. At the same time, the inclined end of the rivet block 311 is initially and slightly locked on the end wall inside the locking hole 810, and the inclined end of the rivet block 311 does not exceed the surface of the reinforcing compensation rivet 8, thus completing the installation and fixing of the reinforcing compensation rivet 8 and preventing the reinforcing compensation rivet 8 from moving when inserted into the rivet hole on the plate body 9 to be riveted. Step Two, Combining Figure 6As shown, after the above operations are completed, since the distance between the extrusion outward expansion part A and the extrusion outward expansion part B is matched with the interlayer width between the two plates 9 to be riveted, the worker can move the entire assembly by hand and insert both ends of the reinforcing compensation rivet 8 into the rivet holes located on the two plates 9 to be riveted, and the two rivet holes are located in the middle of the extrusion outward expansion part A and the middle of the extrusion outward expansion part B, respectively. Step 3, Combining Figure 5 As shown, the staff quickly pushes and pulls the push rod 4 back and forth again, so that the connected ring plate 6 instantly impacts the rivet block 311, which is slightly stuck in the end wall of the locking hole 810, to achieve the effect of punching the inclined end of the rivet block 311 out of the locking hole 810. At this time, the rivet block 311 is in an unreset state, which is conducive to forming a structure that applies inward force to both ends of the extruded and outwardly expanding part. Step 4: Combining Figure 1 and Figure 4 As shown, the operator starts the motor 1 to drive the connected screw tube 2 to rotate. In order to ensure the stability of the movement and riveting of the ring plate 6 and its connected riveting block 311, the connecting ring 510 needs to be manually bound and fixed. This allows the two riveting blocks 311 in each group to move towards each other, which is beneficial to the expansion of the two extrusion expansion parts on the reinforcing and compensating rivet 8. This achieves a firm connection between the extrusion expansion parts of the reinforcing and compensating rivet 8 and the rivet holes on the plate, enhancing the connection strength between the plate layers. This replaces the traditional method of using a large amount of filler material to strengthen the connection strength between the plate layers, greatly reducing the weight of the plate assembly structure. Step 5, as follows Figure 5 and Figure 6 As shown, the locking hole 810 has a certain length, providing sufficient space for the rivet block 311 to reset and move. Thus, the motor 1 drives the screw tube 2 to start running in the reverse direction, causing the corresponding set of ring blocks 6 at the extrusion outward expansion part A and the extrusion outward expansion part B to move in the reverse direction. Combined with the connection between the rivet block 311 and the side groove 310 through the rotating shaft fitted with a torsion spring, the rivet block 311 can be retracted and reset inward with the help of the torsion spring, releasing the connection with the reinforcing compensation rivet 8, making it convenient to remove the whole structure.
