Description

Technical Field

[0001] This invention relates to the field of automotive seat crossbeam processing, and more particularly to an automotive seat crossbeam processing apparatus. Background Technology

[0002] In car seats, the crossbeam structure serves to increase the strength of the seat installation. Existing vehicles, especially SUVs, MPVs, and pickup trucks, generally cannot use a universal seat installation structure; therefore, a separately designed crossbeam structure is required during seat assembly.

[0003] During the production of this type of crossbeam, after the crossbeam is stamped, laser equipment is needed to cut holes and trim the edges. Because the two ends of the crossbeam are raised, the raised parts at both ends of the crossbeam need to be supported to maintain stability during processing. The support parts are of different heights, which causes the crossbeam to be unable to be fed through a straight conveyor. Summary of the Invention

[0004] This invention addresses the shortcomings of existing technologies by providing a processing device for automotive seat crossbeams. It utilizes guide rails for material loading and incorporates a limiting plate, a support plate, and a driving component. The driving component causes the limiting plate to first limit the crossbeam from both ends, and then supports the inner wall of the crossbeam from within. To solve the aforementioned technical problems, this invention provides the following technical solution.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A processing device for an automotive seat crossbeam includes: a support frame; a guide rail disposed on one side of the support frame, the width of the guide rail being less than the width between the inner walls of the crossbeam to facilitate crossbeam movement; limiting plates disposed on both sides of the support frame, the two limiting plates limiting the crossbeam from both ends; and a support plate disposed on the legs of the support frame, the top of the support plate contacting the inner top wall of the crossbeam, and the support plate being offset from the mounting holes.

[0007] Preferably, the guide rail is at the same height as the support plate, which makes the movement of the crossbeam more stable.

[0008] Preferably, the support plates are symmetrically arranged about the legs, and the support frame is provided with guide components that allow the two support plates to move away from each other and closer together. When the two support plates move away from each other, they contact the inner wall of the crossbeam to limit the crossbeam. The two support plates apply forces in different directions, which increases the friction between the support plates and the transverse inner wall, making the crossbeam more stable. The crossbar can also be connected to the support plates to increase the contact area.

[0009] Preferably, the guiding component includes: a guide block with guide surfaces on both sides, which, when in contact with the support plates, cause the two support plates to move away from each other, as shown in the figure. The guide block is located inside the support leg, and the lower part of the guide block contacts the inner wall of the support leg. A through groove is provided on the support leg, and the lower side of the guide block extends from the through groove to facilitate driving; a slide cylinder symmetrically arranged about the support leg, which is slidably connected to the support plates. The slide cylinder has a stabilizing and guiding effect on the movement of the support plates; and a spring disposed inside the slide cylinder, with both ends of the spring connected to the support plates and the inner end of the slide cylinder, respectively. The spring is used to reset the two support plates, thereby releasing the restriction on the crossbeam.

[0010] Preferably, the support plate is rotatably provided with rollers to reduce the resistance of the guide block driving the support plate.

[0011] Preferably, there are two support legs, and the guide components correspond one-to-one with the support legs. The two support legs correspond to two sets of support plates. A synchronization plate is provided between the two guide components to enable the two sets of support plates to move synchronously.

[0012] Preferably, the support frame is provided with a longitudinally sliding plate. The plate is arc-shaped and corresponds to the end of the crossbeam. The mounting holes of the plate and the end of the crossbeam are staggered. A sliding sleeve is connected to the bottom of the plate. The sliding sleeve is in sliding engagement with the support frame. During the movement of the crossbeam, the plate moves down until it no longer obstructs the movement of the crossbeam.

[0013] Preferably, one end of the synchronizing plate is slidably connected to the sliding sleeve in the longitudinal direction. During the upward movement of the sliding sleeve, the synchronizing plate is moved upward along with it. The synchronizing plate causes the guide block to move upward, thereby moving the symmetrical support plates away from each other. The synchronizing plate cannot be connected to the sliding sleeve, reducing the number of driving components and simplifying the structure.

[0014] Preferably, the support frame is provided with a driving component, the driving component including a motor: the motor is connected to a threaded rod, the threaded rod is rotatably engaged with the support frame, a rack is connected to the threaded rod, a first screw and a second screw are rotatably provided on the support frame, the first screw is connected to a first gear, the second screw is connected to a second gear, and the limiting plate includes a limiting part and a sliding part, the limiting part is used to limit the two ends of the crossbeam, and the sliding part is slidably connected to the support frame.

[0015] Preferably, the distance between the first gear and the second gear is greater than the length of the teeth on the rack, so that the limiting plate first limits the crossbeam from both ends, and then limits it from the inner wall of the crossbeam, so that the crossbeam is stably supported.

[0016] Compared with the prior art, the present invention has the following beneficial effects: The present invention facilitates material feeding by setting a guide rail. By setting a limiting plate, a support plate and a driving component, the driving component causes the limiting plate to limit the crossbeam from both ends. Then, the driving component causes the second screw to rotate through the rack. The second screw causes the guide block to rise, thereby moving the symmetrical support plates away from each other. The mutually displaced support plates limit the crossbeam during the movement and are in close contact with the inner wall of the crossbeam, forming a frictional force with the crossbeam in the longitudinal direction, making the crossbeam more stable.

[0028] Please see Figure 1-5 A processing device for automotive seat crossbeams includes: a support frame 1; a guide rail 2, which is disposed on one side of the support frame 1 and is used for feeding the support frame 1. The width of the guide rail 2 is smaller than the width between the inner walls of the crossbeam to facilitate the movement of the crossbeam; two limiting plates 3, one on each side of the support frame 1, which limit the crossbeam from both ends. Both limiting plates 3 are bent outward to facilitate the positioning of the crossbeam. A connecting plate 9 is disposed between the two limiting plates 3 to connect the two limiting plates 3 together; and a support plate 4, which is disposed on the support leg 11 of the support frame 1. The top of the support plate 4 contacts the inner top wall of the crossbeam, and the support plate 4 is misaligned with the mounting hole to prevent it from affecting the processing. The support plate 4 supports the crossbeam. During the feeding process, in order to continuously support the crossbeam, a horizontal bar 12 is disposed on one side of the support leg 11, and the horizontal bar 12 is flush with the support plate 4.

[0029] The guide rail 2 is at the same height as the support plate 4, which makes the movement of the crossbeam more stable.

[0030] The support plates 4 are symmetrically arranged about the legs 11. The support frame 1 is provided with guide components 5 that allow the two support plates 4 to move away from each other and closer together. When the two support plates 4 move away from each other, they contact the inner wall of the crossbeam, thus limiting the crossbeam. The two support plates 4 apply force in different directions and are in close contact with the inner wall of the crossbeam, forming friction with the crossbeam in the longitudinal direction, making the crossbeam more stable. The crossbar 12 can also be connected to the support plates 4 to increase the contact area. Of course, the crossbeam can also be unconnected to the support plates 4, and one end of the crossbar 12 can be connected to the legs 11.

[0031] The guide component 5 includes: a guide block 51 with guide surfaces on both sides, which, when in contact with the support plate 4, cause the two support plates 4 to move away from each other, as shown in the figure. The guide block 51 is located inside the support leg 11, and the lower part of the guide block 51 is in contact with the inner wall of the support leg 11. A through groove is provided on the support leg 11, and the lower side of the guide block 51 extends from the through groove to facilitate driving; a slide cylinder 52, which is symmetrically arranged about the support leg 11. The slide cylinder 52 is slidably connected to the support plate 4, and the slide cylinder 52 has a stabilizing and guiding effect on the movement of the support plate 4; and a spring 53, which is disposed inside the slide cylinder 52. The two ends of the spring 53 are respectively connected to the support plate 4 and the inner end of the slide cylinder 52. The spring 53 is used to reset the two support plates 4, thereby releasing the limit on the crossbeam.

[0032] Rollers 54 are rotatably mounted on the support plate 4 to reduce the resistance of the guide block 51 driving the support plate 4.

[0033] There are two support legs 11. The guide component 5 corresponds to the support leg 11 one by one. The two support legs 11 correspond to the two sets of support plates 4. A synchronization plate 6 is provided between the two guide components 5. The synchronization plate 6 enables the two sets of support plates 4 to move synchronously.

[0034] The support frame 1 is provided with a longitudinally sliding plate 7. The plate 7 is arc-shaped and corresponds to the end of the crossbeam. The mounting holes of the plate 7 and the end of the crossbeam are staggered. A sliding sleeve 71 is connected to the bottom of the plate 7. The sliding sleeve 71 is slidably engaged with the support frame 1. During the movement of the crossbeam, the plate 7 moves down until it no longer obstructs the movement of the crossbeam.

[0035] One end of the synchronizing plate 6 is slidably connected to the sliding sleeve 71 in the longitudinal direction. As the sliding sleeve 71 moves upward, it carries the synchronizing plate 6 upward. The synchronizing plate 6 causes the guide block 51 to move upward, thereby moving the symmetrical support plates 4 away from each other. Through synchronization, they cannot be connected to the sliding sleeve 71, reducing the number of driving components and simplifying the structure. It should be noted that after the guide block 51 moves upward, its upper end cannot exceed the height of the support plate 4. Therefore, the height of the guide surface is lower than the upward movement height, and the support plate 4 has already contacted the crossbeam before the plate body 7 contacts the crossbeam.

[0036] A drive component 8 is provided on the support frame 1. The drive component 8 includes a motor 81. The motor 81 is connected to a threaded rod 82, which is rotatably engaged with the support frame 1. A rack 83 is connected to the threaded rod 82. A first screw 84 and a second screw 85 are rotatably provided on the support frame 1. The first screw 84 is connected to a first gear 86, and the second screw 85 is connected to a second gear 87. The limiting plate 3 includes a limiting part and a sliding part. The limiting part is used to limit the two ends of the crossbeam, and the sliding part is slidably connected to the support frame 1. In use, the motor 81 causes the threaded rod 82 to rotate, and the threaded rod 82 causes the rack 83 to move. During the movement of the rack 83, the limiting plate 3 and the sliding sleeve 71 rise successively, thereby fixing the crossbeam.

[0037] A limit rod 88 is provided on one side of the threaded rod 82. The limit rod 88 limits the rack 83 to prevent the rack 83 from rotating, and the limit rod 88 also has the function of stabilizing the rack 83.

[0038] The distance between the first gear 86 and the second gear 87 is greater than the length of the teeth on the rack 83. This arrangement causes the limiting plate 3 to first limit the crossbeam from both ends, and then limit it from the inner wall of the crossbeam, so that the crossbeam is stably supported.

[0039] In summary, during use, the crossbeam enters the bracket via the guide rail 2, and then the motor 81 is started. The motor 81 drives the threaded rod 82 to rotate, which in turn causes the rack 83 to move. The rack 83 causes the first gear 86 to rotate, which in turn causes the first screw 84 to rotate. The first screw 84 causes the limiting plate 3 connected to it to rise, and the other limiting plate 3 rises together via the connecting plate 9. The limiting part of the limiting plate 3 limits both ends of the crossbeam. Before the rack 83 separates from the first gear 86, it does not mesh with the second gear 87. After the rack 83 separates from the first gear 86, the rack 83 causes the second gear 87 to move. When the second gear 87 rotates, the second screw 85 rotates, and the second screw 85 causes the sliding sleeve 71 to rise. The sliding sleeve 71 carries the plate 7 to rise, and the plate 7 supports the end of the crossbeam. During the rise of the sliding sleeve 71, the synchronous plate 6 is driven to rise, and the synchronous plate 6 drives the two guide blocks 51 to rise. The guide surface of the guide block 51 causes the roller 54 to move, and the roller 54 carries the support plate 4 to move. The support plate 4 slides on the sliding cylinder 52 and stretches the spring 53. Finally, the support plates 4, which move away from each other, limit the crossbeam and then perform processing. After the processing is completed, the motor 81 reverses, causing the parts to reset, thereby removing the crossbeam.

[0040] Those skilled in the art should understand that the embodiments of the present invention described above and shown in the accompanying drawings are merely examples and do not limit the present invention. The objectives of the present invention have been fully and effectively achieved. The functions and structural principles of the present invention have been shown and explained in the embodiments, and any modifications or variations of the embodiments of the present invention may be made without departing from the stated principles.
