Description
Technical Field
[0001] This utility model relates to the field of seat chassis production equipment, and in particular to a riveting device for seat chassis. Background Technology
[0002] In the manufacturing process of seat chassis, the riveting process is a key step in firmly fixing rivets to the chassis components, which plays a decisive role in the overall structural strength and stability of the seat. Currently, most riveting equipment on the market has a fixed distance between the riveting platform and the riveting head. This structure means that the equipment can only be adapted to a single specification or a limited number of seat chassis. When it is necessary to produce seat chassis of different thicknesses and structures, the inability to flexibly adjust the distance between the riveting head and the riveting platform can lead to inappropriate riveting force, affecting the riveting quality of the rivets and reducing the connection strength of the seat chassis. In order to facilitate the riveting of seat chassis of different thicknesses and structures, it is necessary to invent a riveting device for seat chassis to meet the above requirements. Utility Model Content
[0003] The purpose of this invention is to provide a riveting device for seat chassis to solve the problems mentioned in the background art.

A fixing plate is provided on the top of the plate. A T-shaped mounting rod is slidably disposed in the T-shaped mounting groove. A through hole corresponding to the T-shaped mounting rod is opened on the surface of the fixing plate. A thread is provided on the outer side of the vertical part of the T-shaped mounting rod. A locking nut is threadedly connected to the top of the T-shaped mounting rod. A slot is opened on the top of the fixing plate, and a positioning rod is disposed in the slot. A support block is connected to the top of the base. A threaded cylinder is connected to the top of the support block through a bearing. A threaded rod is connected to the top of the threaded cylinder. The top of the threaded rod is connected to the bottom of the movable seat.
[0005] Preferably, a turntable is connected to the outer wall of the threaded cylinder.
[0006] The above settings can be used to drive the threaded cylinder to rotate.
[0007] Preferably, the movable seat has multiple first threaded holes on both the front and rear sides, and the first threaded holes are threaded with first bolts.
[0008] The above settings can be used to increase the friction between the moving seat and the rectangular limiting block, thereby improving the stability during riveting.
[0009] Preferably, the sidewalls of the positioning rod and the slot are provided with corresponding second threaded holes, and the second threaded holes are internally threaded with second bolts.
[0010] The above settings can be used to disassemble and replace positioning rods of different lengths.
[0011] The technical effects and advantages of this utility model are as follows: By setting a threaded rod and a threaded cylinder, when the threaded cylinder is rotated, the threaded rod can push the moving seat to slide up and down through the principle of thread movement, thereby adjusting the distance between the positioning rod and the pressing head.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0017] This utility model provides, for example Figure 1-3The diagram shows a riveting device for a seat chassis, comprising a base 1, a fixed frame 2 fixedly connected to the top of the base 1, a cylinder 3 fixedly connected to the top of the fixed frame 2, and a riveting head 4 fixedly connected to the bottom output end of the cylinder 3. The cylinder 3 controls the up-and-down movement of the riveting head 4, which is used to rivet rivets on the seat chassis. A movable seat 5 is provided on the left side of the fixed frame 2, and a rectangular limiting block 6 is fixedly connected to the left side of the fixed frame 2. A rectangular limiting groove corresponding to the rectangular limiting block 6 is provided on the side wall of the movable seat 5, allowing the movable seat 5 to slide on the rectangular limiting block 6, thereby adjusting the distance between the mounting plate 7 and the riveting head 4. A mounting plate 7 is fixedly connected to the top of the movable seat 5, and a [missing information - likely a design feature] is provided on the top of the mounting plate 7. The T-shaped mounting groove 8 has a fixing plate 9 on the top of the mounting plate 7. A T-shaped mounting rod 10 is slidably installed in the T-shaped mounting groove 8. The surface of the fixing plate 9 has a through hole corresponding to the T-shaped mounting rod 10. The vertical part of the T-shaped mounting rod 10 has a thread on its outer side. The top of the T-shaped mounting rod 10 is threaded with a locking nut 11. A fixing plate 9 for installing a positioning rod 12 can be installed on the mounting plate 7. The top of the fixing plate 9 has a slot, and the positioning rod 12 is installed in the slot. The top of the base 1 is fixedly connected to a support block 13. The top of the support block 13 is connected to a threaded cylinder 14 through a bearing. The top of the threaded cylinder 14 is threadedly connected to a threaded rod 15. The top of the threaded rod 15 is fixedly connected to the bottom of the movable seat 5.
[0018] A turntable 16 is fixedly connected to the outer wall of the threaded cylinder 14. The threaded cylinder 14 can be rotated when the turntable 16 is rotated.
[0019] Multiple first threaded holes are provided on both the front and rear sides of the movable seat 5, and first bolts 17 are threaded into the first threaded holes. When the height of the movable seat 5 needs to be adjusted, the first bolts 17 need to be rotated to loosen them. After the adjustment is completed, the first bolts 17 need to be rotated to tighten them, thereby increasing the friction between the first bolts 17 and the rectangular limit block 6 and improving the stability of the press riveting.
[0020] The positioning rod 12 and the side wall of the slot are provided with corresponding second threaded holes, and the second threaded holes are connected with second bolts 18.

[0021] Working principle of this utility model:
[0022] By rotating the first bolt 17, the first bolt 17 is loosened. By rotating the threaded cylinder 14, the threaded cylinder 14 moves due to the principle of threaded movement and the limitation of the rectangular limiting block 6, causing the threaded rod 15 to move. The threaded rod 15 pushes the moving seat 5, the moving seat 5 pushes the mounting plate 7 on it, the mounting plate 7 pushes the fixed plate 9 installed thereon, and the fixed plate 9 pushes the positioning rod 12 to adjust the distance between the positioning rod 12 and the riveting head 4. After the adjustment is completed, the first bolt 17 needs to be rotated to tighten the first bolt 17, increasing the friction between the first bolt 17 and the rectangular limiting block 6. The seat chassis to be riveted is placed on the positioning rod 12. By using the cylinder 3 to push the riveting head 4, the riveting head 4 can be used to rivet the rivets on the seat chassis.
