Description

Technical Field

[0001] This application relates to the field of riveting equipment for parts, and in particular to a high-efficiency riveting device. Background Technology

[0002] High-adjustment toothed plates and equal-thickness toothed plates are core components of the high-adjustment module of car seats. They enable the adjustment of the car seat height to meet the comfort requirements of passengers of different heights and body types, thereby improving the applicability and user experience of the car seat. The two are usually riveted together.

[0003] The high-profile toothed plate needs to go through a bending process during production. However, the bending process is prone to producing defective products. At this time, the riveting joint between the high-profile toothed plate and the toothed plate of equal thickness is usually removed by the riveting removal equipment, so that the toothed plate of equal thickness can be recycled and reused.

[0004] However, the traditional riveting equipment used by workers is usually a manual benchtop rotary table, which has low work efficiency and obvious shortcomings. Utility Model Content

[0005] To improve riveting efficiency, this application provides a high-efficiency riveting device.

[0006] The high-efficiency riveting removal device provided in this application adopts the following technical solution:

[0007] A high-efficiency riveting removal device includes a worktable and a support block placed on the worktable. The support block has a rivet removal hole for rivet removal. A frame is mounted on the worktable, and a screw jack electrically connected to a control system is arranged on the frame. A rivet removal head is arranged at the bottom end of the screw of the screw jack.

[0008] By adopting the above technical solution, workers manually place the high-adjustment toothed plate and the equal-thickness toothed plate on the support block, and then start the screw jack. The screw jack drives the rivet removal head to slowly descend. The worker visually aligns the riveting joint of the high-adjustment toothed plate and the equal-thickness toothed plate with the rivet removal head. The rivet removal head then forcefully pushes out the rivet at the riveting joint and drops it into the rivet removal hole. The above riveting removal process is simple to operate and has high rivet removal efficiency.

[0009] Optionally, the bearing block has a nail-stacking cavity communicating with the nail-removing hole, and two push-pull plates that abut against each other are slidably arranged at the bottom of the bearing block relative to the bottom opening of the nail-stacking cavity.

[0010] By adopting the above technical solution, after the rivets fall off from the riveting joint, they fall into the rivet stacking cavity through the rivet removal hole. When there are many rivets in the rivet stacking cavity, the worker manually pulls the two push-pull carrier plates away from each other, so that the rivets in the rivet stacking cavity can fall between the two push-pull carrier plates, thus realizing the regular cleaning of rivets.

[0011] Optionally, the support block is provided with an arc groove, the inner arc surface of the arc groove faces upward, and the push-pull support plate extends into the arc groove and slides in cooperation with it.

[0012] By adopting the above technical solution, during the riveting process, the two push-pull carrier plates can maintain a tight-fitting state under the action of gravity.

[0013] Optionally, lugs are provided on both push-pull plates.

[0014] By adopting the above technical solution, the ear-pulling mechanism makes it easier for workers to manually move the two push-pull plates away from each other.

[0015] Optionally, each of the two push-pull plates has a support rod on its opposite side, and a tension spring is attached between the ends of the two support rods.

[0016] By adopting the above technical solution, when the worker manually moves the two push-pull carrier plates away from each other, the tension spring is stretched by the two carrier rods. After the rivets in the pile cavity are emptied, the worker releases the push-pull carrier plates, and the deformation force of the tension spring can pull the two push-pull carrier plates closer to each other to achieve automatic reset.

[0017] Optionally, the support block has an opening on the side facing the worker, and the opening is provided with transparent glass.

[0018] By adopting the above technical solution, the transparent glass allows workers to directly observe the amount of rivets accumulated in the rivet cavity with the naked eye, so that workers can clean it at the appropriate time.

[0019] The push-pull carrier plate has an insertion hole at the position where it extends into the arc groove, and a pin is slidably inserted through the bearing block at the position relative to the end of the arc groove to engage with the insertion hole.

[0020] By adopting the above technical solution, the pin and the socket are engaged, thereby keeping the two push-pull carrier plates in a separated state. The rivets fall directly from the rivet stacking cavity onto the worktable, which facilitates workers to clean the rivets in a centralized and one-time manner.

[0021] Optionally, a pull wire is attached between the outer wall of the bearing block and the pin.

[0022] By adopting the above technical solution, the pull cord reduces the possibility of accidental loss of the pin.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] 1. The worker manually places the high-adjustment toothed plate and the equal-thickness toothed plate on the support block, then starts the screw jack. The screw jack drives the rivet removal head to slowly descend. The worker visually aligns the riveting joint of the high-adjustment toothed plate and the equal-thickness toothed plate with the rivet removal head. The rivet removal head then forcefully pushes out the rivet at the joint and drops it into the rivet removal hole. The above riveting removal process is simple to operate and has high rivet removal efficiency.

[0025] 2. After the rivets fall off from the riveting joint, they fall into the rivet accumulation cavity through the rivet removal hole. When there are many rivets in the rivet accumulation cavity, the worker manually pulls the two push-pull carrier plates away from each other, so that the rivets in the rivet accumulation cavity can fall between the two push-pull carrier plates, thus realizing the regular cleaning of rivets.

[0026] 3. When the worker manually moves the two push-pull plates away from each other, the tension spring is stretched by the two support rods. After the rivets in the pile cavity are emptied, the worker releases the push-pull plates, and the deformation force of the tension spring can pull the two push-pull plates closer together to achieve automatic reset;

[0027] 4. The pin and the socket are engaged to keep the two push-pull plates separated, and the rivets fall directly from the rivet stacking cavity onto the worktable, which makes it convenient for workers to clean the rivets in one go. Attached Figure Description

[0032] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0033] This application discloses an efficient riveting removal device.

[0034] Reference Figure 1 The high-efficiency riveting device includes a worktable 1 and a support block 2 placed on the worktable 1. The support block 2 is used to place the high-adjustment tooth plate and the tooth plate of equal thickness.

[0035] A frame 3 is mounted on the workbench 1. A screw jack 4, which is electrically connected to the control system, is bolted to the frame 3. A screw ejector head 5 is installed at the bottom of the screw of the screw jack 4.

[0036] Reference Figure 2 The top of the bearing block 2 has a vertically opened nail removal hole 201, and the bearing block 2 has a nail stacking cavity 202 communicating with the nail removal hole 201. Two push-pull carrier plates 6 are slidably arranged at the bottom of the bearing block 2 relative to the bottom opening of the nail stacking cavity 202.

[0037] Reference Figure 1 and Figure 2 The worker manually places the high-adjustment toothed plate and the equal-thickness toothed plate on the bearing block 2, and then starts the screw jack 4. The screw jack 4 drives the ejector head 5 to descend slowly.

[0038] During this process, the worker visually aligns the joint between the high-profile toothed plate and the toothed plate of equal thickness with the rivet removal head 5. The rivet removal head 5 then forcefully pushes out the rivet at the joint and drops it into the rivet stacking cavity 202 through the rivet removal hole 201. This rivet removal process is simple to operate and improves the efficiency of rivet removal.

[0039] Reference Figure 1 and Figure 2 Workers can clean the rivets in the rivet stacking cavity 202 either periodically or in one concentrated cleaning. When periodic cleaning is used, the two push-pull carrier plates 6 are pressed against each other during the rivet removal process until a large number of rivets accumulate in the rivet stacking cavity 202. Then, the worker manually pulls the two push-pull carrier plates 6 apart, and the rivets fall between the two push-pull carrier plates 6.

[0040] Reference Figure 1 and Figure 2 When a centralized one-time cleaning is adopted, the two push-pull carrier plates 6 always remain in a state of opposite directions and far apart during the riveting process. The rivets fall directly from the pile cavity 202 onto the pile workbench 1. After the work is completed, the workers directly clean the rivets on the workbench 1 in a centralized one-time manner.

[0041] Reference Figure 2 The support block 2 has an arc groove (not shown in the figure) that is closed at both ends. The inner arc surface of the arc groove faces upward. The push-pull carrier plate 6 extends into the arc groove and slides into it. The opposite sides of the two push-pull carrier plates 6 are integrally formed with carrier rods 8, and tension springs 9 are connected between the ends of the two carrier rods 8.

[0042] Reference Figure 2 and Figure 3 When the worker manually moves the two push-pull carrier plates 6 away from each other, the tension spring 9 is stretched by the two carrier rods 8. After the rivets in the pile cavity 202 are emptied, the worker releases the push-pull carrier plates 6, and the deformation force of the tension spring 9 can pull the two push-pull carrier plates 6 closer to each other to achieve automatic reset.

[0043] Reference Figure 2 and Figure 3 Both push-pull carrier plates 6 are welded with lugs 7, which make it convenient for workers to manually move the push-pull carrier plates 6.

[0044] Reference Figure 2 and Figure 3 The support block 2 has an opening facing the worker, and a transparent glass 10 is glued to the opening. The transparent glass 10 allows the worker to directly observe the amount of rivets accumulated in the rivet cavity 202 with the naked eye, so that the worker can clean it at the appropriate time.

[0045] Reference Figure 2 and Figure 3 The push-pull carrier plate 6 extends into the arc groove and has an insertion hole (not shown in the figure). The bearing block 2 is slidably provided with a pin 11 that engages with the insertion hole at a position relative to the end of the arc groove. The position of the push-pull carrier plate 6 is locked by the engagement of the insertion hole and the pin 11, thereby realizing the centralized and one-time cleaning of the rivets.

[0046] Reference Figure 2 and Figure 3 A pull wire 12 is attached between the outer wall of the bearing block 2 and the pin 11. Since the pin 11 is small in size, the pull wire 12 reduces the possibility of the pin 11 being lost accidentally.

[0047] The implementation principle of the high-efficiency riveting removal device in this application embodiment is as follows: the worker manually places the high-adjustment toothed plate and the equal-thickness toothed plate on the bearing block 2, and then starts the screw jack 4, which drives the riveting removal head 5 to descend slowly.

[0048] During this process, the worker visually aligns the joint between the high-profile toothed plate and the toothed plate of equal thickness with the rivet removal head 5. The rivet removal head 5 then forcefully pushes out the rivet at the joint and drops it into the rivet stacking cavity 202 through the rivet removal hole 201. This rivet removal process is simple to operate and improves the efficiency of rivet removal.

[0049] When periodic cleaning is used, the two push-pull carrier plates 6 are pressed against each other during the riveting process until a large number of rivets accumulate in the rivet accumulation cavity 202. The worker then manually pulls the two push-pull carrier plates 6 apart, and the rivets fall out between the two push-pull carrier plates 6.

[0050] When a centralized one-time cleaning is used, the two push-pull carrier plates 6 always remain in a back-to-back state during the riveting process. The rivets fall directly from the pile cavity 202 onto the pile workbench 1. After the work is completed, the workers can directly perform centralized one-time cleaning of the rivets on the workbench 1.

[0051] 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.
