Description

Technical Field

[0001] This utility model relates to the field of automotive seat manufacturing and processing technology, specifically to a production line seat robot tightening device. Background Technology

[0002] With the rapid development of the automotive industry, car seats, as a core component of automotive interiors, directly affect the comfort and safety of passengers due to their production quality and assembly precision. In the car seat production process, the connection of components such as the seat frame and cushion frame typically relies on bolt tightening. This process demands extremely high precision, consistency, and efficiency in tightening, making it one of the key factors determining the quality of seat production. Currently, there are two main methods for tightening operations on automotive seat production lines: one is manual hand-held tightening with tools. This method is affected by factors such as the operator's experience and physical condition, making it difficult to ensure the consistency and accuracy of tightening torque, and the work efficiency is low, failing to meet the needs of large-scale mass production. In addition, long-term repetitive work can easily lead to worker fatigue and increase the risk of operational errors. The other method is to use fixed robotic tightening equipment. Although this type of equipment improves work efficiency to some extent, it has the problem of insufficient adjustment flexibility. The positions of its limiting mechanism and tightening mechanism are fixed, and it can only be adapted to a single model of seat. When the production model is changed or the seat specifications are changed, the equipment needs to be disassembled and readjusted on a large scale, which is not only time-consuming and labor-intensive, but also causes production line downtime and increases production costs. In view of this, we propose a robotic tightening equipment for automotive seat production lines to solve the existing problems. Utility Model Content

[0003] The purpose of this invention is to provide a production line chair robot tightening device to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a production line seat robot tightening device, including a housing, a tightening device, a slide rail, a limiting mechanism, an adjusting mechanism, and a fixing frame. The fixing frames are symmetrically arranged inside the housing, and each fixing frame is provided with a limiting mechanism. A conveying device is provided inside the housing, and an adjusting mechanism is slidably connected to the conveying device.

[0005] Preferably, the limiting mechanism includes a first slide rail, a limiting seat, a first telescopic cylinder, and a limiting block. The first slide rail is symmetrically arranged on the fixed frame, the limiting seat is slidably connected on the first slide rail, and the first telescopic cylinder is fixedly connected on the fixed frame. The output end of the first telescopic cylinder is fixedly connected to the limiting block.

[0006] Preferably, the adjustment mechanism includes an adjustment frame, a guide frame, a guide block, a transmission rod, a connector, a mounting frame, a movable part, a second slide rail, a second telescopic cylinder, and a telescopic rod. The conveying equipment is provided with a base, and a second slide rail is provided on one side of the base. A second telescopic cylinder is slidably connected to the second slide rail. The output end of the second telescopic cylinder is fixedly connected to the telescopic rod. A mounting frame is fixedly connected to one side of the telescopic rod. A movable part is provided on the mounting frame. A transmission rod is movably connected to the movable part. A connector is provided on the side of the base away from the second slide rail, and a movable part is movably connected to the side of the transmission rod away from the connector.

[0007] Preferably, an adjustment frame is fixedly connected to the mounting frame, a guide frame is fixedly connected to the lower part of the adjustment frame, a limit groove is provided on the guide frame, a guide block is slidably connected in the limit groove, a limit rod is movably connected to the guide block, and a rotating frame is provided on one side of the base and the limit rod is movably connected to the rotating frame.

[0008] Preferably, a tightening device is provided on one side of the fixing frame, a seat is placed on the adjusting frame, and the limiting block and the seat cooperate with each other.

[0009] Compared with the prior art, the beneficial effects of this utility model are: 1. When the seat is conveyed to the tightening operation area by the conveying equipment, firstly, according to the model and size of the seat, the limiting seat can slide and adjust along the first slide rail on the fixed frame to adapt to the limiting requirements of different specifications of seats. The first telescopic cylinder on the fixed frame is activated, and its output end pushes the limiting block to move towards the seat. Since the limiting block and the seat cooperate with each other, the limiting block will contact the corresponding part of the seat, clamping and limiting the seat from both sides to prevent the seat from shifting or shaking during the tightening operation. At this time, the tightening equipment on one side of the fixed frame can perform a precise tightening operation on the seat on the adjusting frame.

[0010] 2. The second slide rail on the base provides a sliding guide for the second telescopic cylinder. The second telescopic cylinder can move laterally along the second slide rail, driving the entire mounting frame and upper components to adjust laterally synchronously, achieving initial alignment between the tightening mechanism and the part of the seat to be tightened. After the second telescopic cylinder is activated, its output end pushes the mounting frame to extend and retract longitudinally through the telescopic rod, further adjusting the distance between the mounting frame and the seat, so that the tightening equipment is close to the position to be worked on. When the mounting frame moves, the movable parts on it drive the transmission rod to move. Since the two ends of the transmission rod are movably connected to the movable parts and the connecting parts respectively, the linear motion of the mounting frame can be converted into a stable posture adjustment, ensuring the levelness and stability of the mounting frame during the adjustment process.

[0011] 3. When the mounting frame moves, the adjusting frame drives the guide frame to move synchronously. The limiting groove on the guide frame and the guide block form a sliding fit, which restricts the movement trajectory of the adjusting frame and prevents deviation. When the adjusting frame is raised, lowered or moved horizontally, the limiting rod rotates around the rotating frame, and the guide block slides in the limiting groove, which further enhances the rigidity and stability of the adjusting mechanism and avoids shaking during operation.

[0014] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this utility model. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of this utility model.

[0015] like Figures 1-4 As shown, the present invention proposes a production line seat robot tightening device, including a housing 1, a tightening device 2, a slide rail, a limiting mechanism 4, an adjusting mechanism 5, and a fixing frame 6. The fixing frames 6 are symmetrically arranged inside the housing 1, and each fixing frame 6 is provided with a limiting mechanism 4. The housing 1 is also provided with a conveying device 3, and the adjusting mechanism 5 is slidably connected to the conveying device 3.

[0016] In an optional embodiment, the limiting mechanism 4 includes a first slide rail 401, a limiting seat 402, a first telescopic cylinder 403, and a limiting block 404. The first slide rail 401 is symmetrically arranged on the fixed frame 6, the limiting seat 402 is slidably connected to the first slide rail 401, and the first telescopic cylinder 403 is fixedly connected to the fixed frame 6. The output end of the first telescopic cylinder 403 is fixedly connected to the limiting block 404.

[0017] In an optional embodiment, a tightening device 2 is provided on one side of the fixing frame 6, a seat is placed on the adjusting frame 501, and the limiting block 404 cooperates with the seat. When the seat is conveyed to the tightening operation area by the conveying device 3, firstly, according to the model and size of the seat, the limiting seat 402 can slide and adjust along the first slide rail 401 on the fixed frame 6 to adapt to the limiting requirements of different specifications of seats. The first telescopic cylinder 403 on the fixed frame 6 is activated, and its output end pushes the limiting block 404 to move towards the seat. Since the limiting block 404 and the seat cooperate with each other, the limiting block 404 will contact the corresponding part of the seat and clamp and limit the seat from both sides to prevent the seat from shifting or shaking during the tightening operation. At this time, the tightening device 2 on one side of the fixed frame 6 can perform a precise tightening operation on the seat on the adjusting frame 501.

[0018] In an optional embodiment, the adjustment mechanism 5 includes an adjustment frame 501, a guide frame 502, a guide block 503, a transmission rod 504, a connector 505, a mounting frame 506, a movable part 507, a second slide rail 508, a second telescopic cylinder 509, and a telescopic rod 510. The conveying device 3 is provided with a base 511, and a second slide rail 508 is provided on one side of the base 511. A second telescopic cylinder 509 is slidably connected to the second slide rail 508. The output end of the second telescopic cylinder 509 is fixedly connected to the telescopic rod 510. A mounting frame 506 is fixedly connected to one side of the telescopic rod 510. A movable part 507 is provided on the mounting frame 506. A transmission rod 504 is movably connected to the movable part 507. A connector 505 is provided on the side of the base 511 away from the second slide rail 508, and a movable part 507 is movably connected to the side of the transmission rod 504 away from the connector 505.

[0019] In an optional embodiment, an adjusting frame 501 is fixedly connected to the mounting frame 506, and a guide frame 502 is fixedly connected to the adjusting frame 501. A limiting groove 514 is provided on the guide frame 502, and a guide block 503 is slidably connected in the limiting groove 514. A limiting rod 513 is movably connected to the guide block 503, and a rotating frame 512 is provided on the base 511 on one side of the connector 505. The limiting rod 513 is movably connected to the rotating frame 512. The second slide rail 508 on the base 511 provides a sliding guide for the second telescopic cylinder 509. The second telescopic cylinder 509 can move laterally along the second slide rail 508, driving the entire mounting frame 506 and the upper components to adjust laterally synchronously, so as to achieve the initial alignment of the tightening mechanism with the part of the seat to be tightened. After the second telescopic cylinder 509 is started, its output end pushes the mounting frame 506 to extend and retract longitudinally through the telescopic rod 510, further adjusting the distance between the mounting frame 506 and the seat, so that the tightening device 2 is close to the position to be worked. When the mounting frame 506 moves, the movable part 507 on it drives the transmission rod 504 to move. Since the two ends of the transmission rod 504 are movably connected to the movable part 507 and the connecting part 505 respectively, the linear motion of the mounting frame 506 can be converted into a stable posture adjustment, ensuring the levelness and stability of the mounting frame 506 during the adjustment process. Simultaneously, when the mounting frame 506 moves, the adjusting frame 501 synchronously drives the guide frame 502 to move. The limiting groove 514 on the guide frame 502 and the guide block 503 form a sliding fit, which restricts the movement trajectory of the adjusting frame 501 and prevents deviation. When the adjusting frame 501 is raised, lowered or moved horizontally, the limiting rod 513 rotates around the rotating frame 512, and the guide block 503 slides in the limiting groove 514, which further enhances the rigidity and stability of the adjusting mechanism and avoids shaking during operation.

[0020] The working principle of this utility model is as follows: When using this device, when the seat is transported to the tightening operation area by the conveying device 3, firstly, according to the model and size of the seat, the limiting seat 402 can slide and adjust along the first slide rail 401 on the fixed frame 6 to adapt to the limiting requirements of different specifications of seats. The first telescopic cylinder 403 on the fixed frame 6 is activated, and its output end pushes the limiting block 404 to move towards the seat. Since the limiting block 404 and the seat cooperate with each other, the limiting block 404 will contact the corresponding part of the seat and clamp and limit the seat from both sides to prevent the seat from shifting or shaking during the tightening operation. At this time, the tightening device 2 on one side of the fixed frame 6 can perform a precise tightening operation on the seat on the adjusting frame 501. The second slide rail 508 on the base 511 provides a sliding guide for the second telescopic cylinder 509. The second telescopic cylinder 509 can move laterally along the second slide rail 508, driving the entire mounting frame 506 and the upper components to adjust laterally synchronously, so as to achieve the initial alignment of the tightening mechanism with the part of the seat to be tightened. After the second telescopic cylinder 509 is started, its output end pushes the mounting frame 506 to extend and retract longitudinally through the telescopic rod 510, further adjusting the distance between the mounting frame 506 and the seat, so that the tightening device 2 is close to the position to be worked. When the mounting frame 506 moves, the movable part 507 on it drives the transmission rod 504 to move. Since the two ends of the transmission rod 504 are movably connected to the movable part 507 and the connecting part 505 respectively, the linear motion of the mounting frame 506 can be converted into a stable posture adjustment, ensuring the levelness and stability of the mounting frame 506 during the adjustment process. Simultaneously, when the mounting frame 506 moves, the adjusting frame 501 synchronously drives the guide frame 502 to move. The limiting groove 514 on the guide frame 502 and the guide block 503 form a sliding fit, which restricts the movement trajectory of the adjusting frame 501 and prevents deviation. When the adjusting frame 501 is raised, lowered or moved horizontally, the limiting rod 513 rotates around the rotating frame 512, and the guide block 503 slides in the limiting groove 514, which further enhances the rigidity and stability of the adjusting mechanism and avoids shaking during operation.
