Technical Field

[0001] This utility model relates to the field of clamping equipment technology, and in particular to a seat clamp. Background Technology

[0002] Currently, on the seat assembly line, the unloading and handling of the seats after assembly is generally done manually. However, this manual handling method has significant technical drawbacks: First, it can cause harm to the human body, as workers need to frequently perform unnatural actions such as grabbing heavy objects, bending over, and twisting. Long-term work can easily lead to musculoskeletal damage and affect human health. Second, it is inefficient. Manual handling under high-intensity conditions consumes a lot of physical strength, causing the handling speed to decrease significantly as the working time increases, and it is difficult to meet the current demand for rapid handling.

[0023] This utility model provides a seat clamp, and the following describes one embodiment of this utility model in detail with reference to the accompanying drawings.

[0024] Combination Figure 1 , Figure 2 as well as Figure 3 As shown, a seat clamp includes a clamping rod 1, a rotating mechanism, and a clamping mechanism. The rotating mechanism is mounted on the clamping rod 1, and a U-shaped operating handle 2 is fixedly connected to the clamping rod 1, located above the rotating mechanism. The rotating mechanism includes a tilting cylinder 4, a rack 14, a driving wheel 15, and a driven wheel 16. The tilting cylinder 4, driving wheel 15, and driven wheel 16 are all mounted on the clamping rod 1, with the driving wheel 15 and driven wheel 16 located below the tilting cylinder 4. The driving wheel 15 and driven wheel 16 are meshed with each other, and the rack 14 is meshed with the driving wheel 15. The upper end of the tilting cylinder 4 is rotatably connected to the clamping rod 1, and the rack 14 is located on one side of the tilting cylinder 4. The rack 14 extends outward from the side adjacent to the tilting cylinder 4, forming an L-shaped extension 13, and the end of the tilting cylinder 4 is rotatably connected to the extension 13. The rack 14 has several first adjustment holes along its length, and the connecting plate has several second adjustment holes that are adapted to the first adjustment holes. The length of the rack 14 relative to the drive wheel 15 is adjusted by the cooperation of the first adjustment holes and the second adjustment holes between the connecting plate and the rack 14.

[0025] Combination Figure 4 and Figure 5As shown, the driving wheel 15 is rotatably connected to the clamping rod 1. A limiting plate 17 is provided on the driving wheel 15. The inner end of the limiting plate 17 is fixedly connected to the clamping rod 1 via a limiting connecting rod. The driving wheel 15 is sleeved on the limiting connecting rod, and the driving wheel 15 rotates relative to the limiting plate 17. A limiting wheel 18 is rotatably connected to the outer end of the limiting plate 17. A rack 14 is located between the limiting wheel 18 and the driving wheel 15, and the limiting wheel 18 is in contact with the rack 14. The limiting plate 17 and the limiting wheel 18 cooperate to ensure the stable movement of the rack 14. The diameter of the driving wheel 15 is smaller than the diameter of the driven wheel 16 to prevent the rack 14 from contacting the driven wheel 16 during movement. In this embodiment, a protective shell 3 is provided outside the rack 14, the driving wheel 15, and the driven wheel 16, and the protective shell 3 is fixedly connected to the clamping rod 1.

[0026] The clamping mechanism includes a rotating plate 5, clamping cylinders 7, an adjusting rod 6, claws 9, clamping arms 10, and grippers. A driven wheel 16 is fixedly connected to a rotating shaft, which passes through the clamping rod 1 and is fixedly connected to the rotating plate 5. The rotating plate 5 is fixedly connected to the adjusting rod 6. In this embodiment, the driven wheel 16 is added to reduce the length of the rack 14. Two clamping cylinders 7 are fixedly connected to one side of the adjusting rod 6 adjacent to the clamping rod 1. There are two claws 9, each perpendicular to the adjusting rod 6, and a buffer pad is provided on the upper surface of each claw 9. An L-shaped plate 8 is fixedly connected to one end of the claw 9, and a slider is fixedly connected inside the L-shaped plate 8. A slide rail is fixedly connected to the adjusting rod 6, and the slider moves along the slide rail accordingly. The L-shaped plate 8 is fixedly connected to the adjusting rod 6 with bolts. In this embodiment, the slider and slide rail cooperate to improve the stability of the claw 9 during its movement along the adjusting rod 6. The clamping arm 10 is L-shaped. One side of the clamping arm 10 is fixedly connected to the piston rod of the clamping cylinder 7, and the other side of the clamping arm 10 is fixedly connected to a quick-change slot 11. The quick-change slot 11 can move along the clamping arm 10 to adjust its position on the clamping arm 10, thereby adjusting the position of the gripper. The gripper is T-shaped, and the upper part of the gripper moves along the clamping arm 10 and is fixedly connected to the clamping arm 10 by bolts.

[0027] In this embodiment, the gripper is specifically designed for use with cushionless seats. The gripper includes a support rod and a pressure rod 19. The lower end of the support rod is fixedly connected to the pressure rod 19, and the upper end is fitted into a quick-change slot 11. The quick-change slot 11 secures the support rod with several bolts. The pressure rod 19 has a rectangular cross-section, and a cushioning pad is provided on its lower surface. The cushioning pad prevents the gripper 9 and the gripper from damaging the seat, and also achieves full contact with the seat through deformation, improving the stability of holding the seat.

[0028] In use, the clamping rod 1 is fixedly connected to the lifting host via a flange. The lifting host is used to drive the clamping rod 1 to rise, fall, and move. The operator holds the operating handle 2 to move the entire unit. When it reaches the appropriate position, the operator controls the clamping cylinder 7 to raise the clamping arm 10, creating a gap between the clamping claw and the support claw 9, and inserting the support claw 9 between the bottom of the seat and the bearing surface. Finally, the operator controls the clamping cylinder 7 to lower the clamping arm 10, causing the clamping claw to gradually approach the support claw 9, thereby clamping the seat. The buffer pads located on the support claw 9 and the clamping claw can isolate direct contact with the seat, avoiding friction and collision. At the same time, the buffer pads can deform to adapt to the seat, increasing the contact area with the seat, making the seat movement more stable and preventing the seat from falling. When the installation or placement angle of the seat needs to be adjusted, the operator controls the reversing cylinder to move the rack 14 downwards. The rack 14 meshes with the driving wheel 15, which in turn meshes with the driven wheel 16. The driven wheel 16 drives the clamping mechanism to rotate, thereby rotating the seat. The operator can adjust the rotation angle of the clamping mechanism by extending or retracting the piston rod in the reversing cylinder 4. The middle part of the rack 14 meshes with the driving wheel 15, so the reversing cylinder 4 drives the driving wheel 15 to rotate counterclockwise or clockwise by extending or retracting, thus rotating the seat counterclockwise or clockwise. During rotation, the rack 14 is positioned between the limiting wheel 18 and the driving wheel 15. The limiting wheel 18 and the driving wheel 15 work together to improve the stability of the rack 14's movement, thereby improving the stability of the clamping mechanism's rotation.

[0029] The following describes another embodiment of the present invention in detail with reference to the accompanying drawings. In order to be applicable to different seats, this embodiment provides another structure of the gripper. In this embodiment, except for the structure of the gripper which is different from that described above, the rest of the structure is the same.

[0030] like Figure 6 As shown, in this embodiment, the gripper is specifically designed for use with cushioned seats. The gripper includes a support rod and a pressure plate 12. The lower end of the support rod is rotatably connected to the pressure plate 12, and the upper section is fitted into a quick-change slot 11. The quick-change slot 11 secures the support rod with several bolts. The bottom of the pressure plate 12 has an arc-shaped cross-section, and a buffer pad is provided on the arc-shaped surface at the bottom of the pressure plate 12. The quick-change slot 11 is used for quick disassembly and installation of the gripper, simplifying operation and improving ease of use.

[0031] Of course, the above description is not intended to limit the present utility model, and the present utility model is not limited to the examples given above. Any changes, modifications, additions or substitutions made by those skilled in the art within the scope of the present utility model should also fall within the protection scope of the present utility model.
