Description
Technical Field
[0001] This utility model relates to the field of seat retainer assembly technology, and in particular to an automotive seat retainer assembly table. Background Technology
[0002] In automotive seat slide rail systems, the retainer is a frame component used to accommodate, position, and guide the movement of the ball bearings. Its function is to ensure that the ball bearings roll orderly within the slide rail track, without scattering or misaligning, thereby achieving smooth adjustment of the seat slide rail. If there is a deviation in the assembly position of the retainer and the upper rail, or if it shifts during subsequent engagement with the lower rail and ball bearings, it can easily cause problems such as slide rail jamming, abnormal noise, or even seizing, affecting the adjustment experience and service life of the automotive seat.
[0003] A search revealed Chinese patent CN221019557U, which provides an assembly mechanism for automotive seat slide rail retainers. This mechanism employs a push assembly, a slide rail positioning assembly, a transition hopper assembly, and a feeding assembly to avoid issues such as unstable insertion depth, detachment, or omissions that can occur with manual assembly of automotive seat slide rail retainers. This ensures the stability of subsequent slide rail assembly processes and prevents abnormal noises or jamming of the seat slide rails.
[0004] However, during use, it was found that the clamping and positioning accuracy of the cage is limited, and the connection between the cage and the upper rail is prone to misalignment, which leads to unstable subsequent ball insertion depth. The movement process of the cage on the upper rail and the cooperation efficiency with the lower rail are low, which is not conducive to the rapid mass assembly and use of automotive seat cages.

Detailed Implementation
[0029] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.
[0030] like Figures 1-6 As shown, this embodiment provides an automotive seat retainer assembly platform, including a workbench 100. The workbench 100 includes a pre-assembly platform 101 and a clamping platform 102. The pre-assembly platform 101 and the clamping platform 102 are fixedly connected. The top surface of the pre-assembly platform 101 is provided with a pre-assembly component 200. Two ball bearing mounting components 300 are installed at one end of the top surface of the pre-assembly platform 101. A lower rail 400 is inserted into the clamping platform 102.
[0031] The pre-assembled component 200 includes a movable block 201. The lower end of the movable block 201 is slidably connected to the upper end of the pre-assembled platform 101 via a guide rail 202. An upper rail 500 is placed on the upper end of the movable block 201. A pressure block 204 is inserted into one end of the movable block 201. The bottom surface of the pressure block 204 is inclined and abuts against the top surface of the upper rail 500.
[0032] Two positioning blocks 206 are fixed on the top surface of the pre-assembly platform 101. A slider 207 is fixed on the outer side of the positioning block 206. A locking block 208 is slidably connected to the slider 207. A retainer 600 is locked to the inner wall of the locking block 208. The two retainers 600 are respectively installed at both ends of the upper rail 500 by connecting bolts 210. Multiple mounting holes 700 are opened on the retainer 600.
[0033] A first cylinder 205 is installed on one side wall of the moving block 201. The piston rod of the first cylinder 205 is fixedly connected to the pressure block 204. A lead screw 212 is threadedly connected to the middle of the locking block 208. One end of the lead screw 212 is rotatably connected to the positioning block 206. Second servo motors 213 are respectively installed on the side walls of both ends of the pre-assembly platform 101. The output shaft of the second servo motor 213 is coaxially connected to the lead screw 212. The output shafts of the two second servo motors 213 drive the coaxially connected lead screw 212 to rotate. Because the locking block 208 is threadedly connected to the lead screw 212 and slides with the slider 207, the rotation of the lead screw 212 drives the locking block 208 to slide smoothly along the slider 207, ensuring that the mounting holes at both ends of the retainer 600 and the upper rail 500 are aligned. After alignment, the locking block 208 is fixed by connecting bolts 210.
[0034] A rack 214 is embedded in the bottom surface of the guide rail 202. A first gear 211 is meshed with the lower end of the rack 214. A rotating shaft 209 is rotatably connected to the middle of the first gear 211. The outer peripheral wall of the rotating shaft 209 is rotatably connected to the pre-assembly platform 101. A first servo motor 203 is installed on the outer peripheral wall of the pre-assembly platform 101. The output shaft of the first servo motor 203 is coaxially connected to the rotating shaft 209. The output shaft of the first servo motor 203 drives the rotating shaft 209 and the first gear 211 to rotate. The first gear 211 meshes with the rack 214 to drive the moving block 201 to slide along the guide rail 202.
[0035] Two second cylinders 103 are installed at both ends of the clamping table 102. The piston rods of the two second cylinders 103 are slidably connected to the clamping table 102, and the piston rods of the two second cylinders 103 abut against the outer wall of the lower rail 400. The piston rods of the second cylinders 103 clamp and position the lower rail 400 to prevent the centering deviation caused by the displacement of the lower rail 400 during docking, thereby improving the docking effect between the upper rail 500 and the lower rail 400.
[0036] The ball bearing mounting assembly 300 includes two material boxes 301. The bottom surfaces of the two material boxes 301 are fixedly connected to the top surface of the pre-assembly platform 101. A distribution block 302 is fixedly provided on the side wall of the material box 301. Two conveying grooves 303 are opened inside the distribution block 302. Multiple ball bearing bodies 304 are conveyed inside the conveying grooves 303. The outlet of the conveying groove 303 corresponds to the mounting hole 700. The conveying grooves 303 and the material boxes 301 are connected. Two distribution discs 305 are rotatably connected at the connection between the distribution block 302 and the material box 301. The outer peripheral wall of the central shaft of the distribution disc 305 is rotatably connected to the distribution block 302. Multiple rotating rods 306 are rotatably connected to the distribution block 302. A second gear 307 is sleeved on the central shaft of the 06 and the distribution plate 305 respectively. Adjacent second gears 307 are meshed and connected. A third servo motor 308 is installed on the outer wall of the distribution block 302. The output shaft of the third servo motor 308 is coaxially connected to the rotating rod 306 located in the middle. The third servo motor 308 drives the rotating rod 306 in the middle to rotate. The second gear 307 on the rotating rod 306 meshes with the second gear 307 on the central shaft of the distribution plate 305, driving the two distribution plates 305 to rotate synchronously at the connection between the distribution block 302 and the material box 301, so that the ball bodies 304 in the material box 301 are introduced one by one and in an orderly manner into the conveying groove 303 of the distribution block 302.
[0037] The outer wall of the cage 600 is slidably connected to the material distribution block 302, and the outer peripheral wall of the ball body 304 inside the mounting hole 700 is slidably connected to the inner wall of the lower rail 400 and the cage 600 respectively. The ball body 304 falls into the mounting hole 700 through the conveying groove 303, realizing the sliding fit between the ball body 304 and the inner wall of the lower rail 400 and the cage 600, completing the overall assembly, and reducing the problems of slide rail jamming and abnormal noise caused by ball position deviation.
[0038] Working principle: The movable block 201 of the pre-assembly component 200 is slidably connected to the pre-assembly platform 101 via the lower guide rail 202. After the upper rail 500 is placed on the upper end of the movable block 201, the pressure block 204 at one end of the movable block 201 abuts against the top surface of the upper rail 500 to achieve positioning and fixation of the upper rail 500. The retainer 600 is snapped into the inner wall of the retainer 208 by the sliding engagement of the locking block 208 and the slider 207. The two retainers 600 are respectively installed at both ends of the upper rail 500 by the connecting bolts 210.
[0039] After the cage 600 and the upper rail 500 are assembled, the moving block 201 slides along the guide rail 202, driving the upper rail 500 with the assembled cage 600 to move towards the clamping table 102. In conjunction with the ball bearing mounting assembly 300 on the pre-assembly table 101, the balls are inserted into the mounting holes 700 of the cage 600 and the upper rail 500 is docked with the lower rail 400. This reduces the offset of the cage 600 during clamping, improves the clamping positioning accuracy, improves the alignment effect of the cage 600 and the upper rail 500 and lower rail 400, improves the docking efficiency, and facilitates the rapid batch assembly of automotive seat cages.
[0040] The piston rod of the first cylinder 205 drives the pressure block 204 to move, so that the inclined bottom surface of the pressure block 204 abuts against the top surface of the upper rail 500. When the cage 600 is clamped, the output shafts of the two second servo motors 213 drive the coaxially connected lead screw 212 to rotate. Since the locking block 208 is threadedly connected to the lead screw 212 and slides with the slider 207, the rotation of the lead screw 212 drives the locking block 208 to slide smoothly along the slider 207, ensuring that the mounting holes at both ends of the cage 600 and the upper rail 500 are aligned. After alignment, it is fixed by the connecting bolts 210.
[0041] After the bolt connection between the retainer 600 and the upper rail 500 is completed, when the upper rail 500 is moved towards the clamping table 102, the output shaft of the first servo motor 203 drives the rotating shaft 209 and the first gear 211 to rotate. The first gear 211 meshes with the rack 214 to drive the moving block 201 to slide along the guide rail 202. At the same time, the piston rod of the second cylinder 103 clamps and positions the lower rail 400 to prevent the centering deviation caused by the displacement of the lower rail 400 during docking, thereby improving the docking effect between the upper rail 500 and the lower rail 400.
[0042] When the installed retainer 600 is moved to the ball bearing mounting position, the material box 301 stores the ball bearing body 304. The third servo motor 308 drives the central rotating rod 306 to rotate. The second gear 307 on the rotating rod 306 meshes with the second gear 307 on the central shaft of the distribution plate 305, driving the two distribution plates 305 to rotate synchronously at the connection between the distribution block 302 and the material box 301. The ball bearing body 304 in the material box 301 is guided one by one and in an orderly manner into the conveying groove 303 of the distribution block 302. Since the outlet of the conveying groove 303 corresponds to the mounting hole 700 of the retainer 600, and the outer wall of the retainer 600 slides with the distribution block 302, the ball bearing body 304 falls into the mounting hole 700 through the conveying groove 303. This achieves the sliding fit between the ball bearing body 304 and the inner wall of the lower rail 400 and the retainer 600, completing the overall assembly and reducing the problems of slide rail jamming and abnormal noise caused by ball bearing position deviation.
[0043] After assembly, the pressure block 204 separates from the upper rail 500, and the guide rail 202 and rack 214 retract from the lower rail 400. At this time, the guide rail 202 drives the moving block 201 to reset to the initial position, and the second cylinder 103 separates from the lower rail 400, which facilitates the separation and removal of the assembled lower rail 400, upper rail 500 and retainer 600 from the clamping table 102, improving assembly efficiency, facilitating continuous operation, and meeting the rapid batch assembly requirements of the automotive seat retainer 600.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
