Description

Technical Field

[0001] This utility model belongs to the field of automotive assembly technology, specifically relating to a multi-platform vehicle compatible co-line tray. Background Technology

[0002] Cross-platform vehicle compatibility on a shared production line refers to automakers sharing assembly processes across different platforms to optimize production efficiency and costs. Cross-platform production typically involves assembling multiple vehicle models on the same production line, making full use of existing production facilities and resources and reducing redundant construction and investment.

[0003] Considering that traditional pallets can only be used for overall assembly on platform assembly lines of the same size, and with the improvement of automotive assembly technology, the existing new platform assembly lines have higher assembly efficiency. The spacing of the moving wheels of some original pallets is not suitable for the guide rails of the new platform assembly lines, making the original pallets unusable and requiring new customization. This process is time-consuming and costly, and the pallets cannot be used across platforms.

[0004] To this end, our patent document with authorization number CN220722493U discloses an automotive cross-platform assembly pallet, which includes a pallet body and a support plate installed below the pallet body. Two symmetrical movable frames are installed on the lower surface of the support plate, and a motor assembly is installed on one side. Each of the two movable frames is equipped with two slide rods and a bidirectional lead screw assembly. One side of the motor assembly is drivenly connected to the bidirectional lead screw assembly. Two symmetrical movable blocks are slidably connected on the slide rods. A first chain is connected between the two bidirectional lead screw assemblies and is connected to the two movable blocks, which facilitates the adjustment of the working distance of the movable wheels and can be applied to new platform assembly lines.

[0005] However, the above technical solutions still have the following problems that need to be optimized in actual work: 1. Since the pallets required on different platforms will be different, such as the size and structure of the chassis and body parts of different platforms will be different, the above pallet main body has the problem of inconvenience in pallet replacement, which affects the replacement efficiency when used across platforms; 2. The degree of automation of platform assembly is getting higher and higher now, and the above platforms lack autonomous drive and are difficult to servo control. Utility Model Content

[0006] This utility model provides a multi-platform compatible co-line tray. By controlling a double-headed telescopic cylinder to extend and retract the telescopic rod, it simultaneously adjusts the spacing of the sliding plates on both sides, thereby adjusting the spacing of the two limit wheels. This allows a single support platform to be compatible with multiple platform assemblies. The fixed and detachable trays can be installed and removed, enabling quick replacement of different trays and facilitating compatibility with more platforms, thus solving the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a multi-platform vehicle compatible co-line tray, comprising a tray mounted on a support platform, with fixed frames on both sides of the bottom surface of the support platform, and two parallel guide rails perpendicular to the direction of the fixed frames welded to the bottom surface of the fixed frames, with sliding plates mounted at both ends of the guide rails; a mounting frame is mounted on the lower center of the support platform, and a double-headed telescopic cylinder is fixed thereon, with the two piston rods of the double-headed telescopic cylinder fixedly connected to the sliding plates on both sides; a rotating shaft is mounted at the bottom end of the sliding plates on both sides, and a limit wheel is mounted on the rotating shaft, with the limit wheel pressing against the track line.

[0008] Preferably, the two corresponding rotating shafts are provided with splines at their close ends, and a rotatable sleeve is mounted on the mounting bracket via a bearing. The sleeve is provided with a spline groove corresponding to the spline.

[0009] Preferably, a servo motor is mounted at the bottom of the slide plate, a pulley is mounted at the end of the servo motor, and a corresponding pulley is mounted on one side of the rotating shaft, which is connected by a synchronous belt.

[0010] Preferably, a telescopic cylinder is fixed to the bottom surface of the support platform. The telescopic cylinder is a multi-stage telescopic cylinder. The support platform is provided with a hole for the piston rod of the telescopic cylinder to pass through. The tray is connected to the piston rod of the telescopic cylinder.

[0011] Preferably, the tray includes a fixed tray and a detachable tray, the fixed tray being fixedly connected to the piston rod of the telescopic cylinder, and the detachable tray being detachably connected to the fixed tray.

[0012] Preferably, the fixed plate includes a square frame and a support frame located inside the square frame. The square frame has screw holes on its four sides. The bottom of the detachable plate has an outer frame with screw holes corresponding to the square frame, and the outer frame is fixedly connected by screws.

[0013] Preferably, the square frame is provided with guide rods at the bottom of its four corners, and the support platform is provided with guide holes corresponding to the guide rods.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. To adapt to different platform track lines, the telescopic rod is extended and retracted by controlling the double-headed telescopic cylinder, which simultaneously drives the sliding plates on both sides to adjust the spacing, thereby adjusting the spacing of the two limit wheels, so that one support platform can be used for the assembly of multiple platforms.

[0016] 2. The fixed and detachable trays can be installed and removed by unscrewing the screws, allowing for quick replacement of different trays and facilitating compatibility with more platforms. Attached Figure Description

[0022] 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.

[0023] Please see Figure 1-4 This utility model provides a multi-platform compatible co-line tray, including a tray 1, which is mounted on a support platform 2. The support platform 2 has fixed frames 3 on both sides of its bottom surface, and two parallel guide rails 4 perpendicular to their direction are welded to the bottom surface of the fixed frames 3. Slide plates 5 are mounted at both ends of the guide rails 4. A mounting frame 6 is mounted below the center of the support platform 2, and a double-headed telescopic cylinder 7 is fixed thereon. The two piston rods of the double-headed telescopic cylinder 7 are fixedly connected to the slide plates 5 on both sides. A rotating shaft 8 is mounted at the bottom end of each slide plate 5, and a limiting wheel 9 is mounted on the rotating shaft 8. The limiting wheel 9 presses against the track line 10. During operation, the tray 1 supports the assembled vehicle body, and the positioning pins on the tray maintain the precise position of the chassis workpiece. To adapt to different platform track lines, the double-headed telescopic cylinder 7 is controlled to extend and retract the telescopic rod, simultaneously adjusting the spacing of the slide plates 5 on both sides, thereby adjusting the spacing of the two limiting wheels 9. This allows one support platform 2 to be compatible with multiple platforms.

[0024] Specifically, the two corresponding rotating shafts 8 are provided with a spline 11 at their close ends, and a rotatable sleeve 12 is mounted on the mounting bracket 6 via a bearing. The sleeve 12 is provided with a spline groove corresponding to the spline 11. In this embodiment, the rotating shafts 8 on both sides can move synchronously through the spline groove of the sleeve 12 and the spline 11, and can still be used after extension and retraction adjustment.

[0025] Specifically, a servo motor 13 is mounted at the bottom of the slide plate 5, and a pulley is mounted at the end of the servo motor 13. A corresponding pulley is mounted on one side of the rotating shaft 8, which is connected by a synchronous belt. In this embodiment, starting the servo motor 13 drives the pulley to rotate, which in turn drives the rotating shaft 8 and the limiting wheel 9 on one side to rotate, thereby driving the sleeve 12 to rotate. Through the cooperation of the spline 11 and the spline groove of the sleeve 12, the rotating shaft 8 and the limiting wheel 9 on the other side are driven to rotate synchronously, thereby controlling the servo movement of the tray 1.

[0026] Specifically, a telescopic cylinder 14 is fixed on the bottom surface of the support platform 2. The telescopic cylinder 14 is a multi-stage telescopic cylinder. The support platform 2 is provided with a hole for the piston rod of the telescopic cylinder 14 to pass through. The tray 1 is connected to the piston rod of the telescopic cylinder 14. In this embodiment, the tray 1 is raised and lowered by the telescopic cylinder 14, and the height of the tray 1 can be adjusted to facilitate assembly and adaptation at different heights.

[0027] Specifically, the tray 1 includes a fixed tray 15 and a detachable tray 16. The fixed tray 15 is fixedly connected to the piston rod of the telescopic cylinder 14, and the detachable tray 16 is detachably connected to the fixed tray 15. In this embodiment, the fixed tray 15 and the detachable tray 16 can be installed and removed, so that different detachable trays 16 can be quickly replaced, which is convenient for use on more platforms.

[0028] Specifically, the fixed plate 15 includes a square frame and a support frame located inside the square frame. The square frame has screw holes on its four sides. The detachable plate 16 has an outer frame 17 at its bottom. The outer frame 17 has screw holes corresponding to the square frame and is fixedly connected by screws 18. In this embodiment, the fixed plate 15 and the detachable plate 16 can be assembled and disassembled by unscrewing the screws 18.

[0029] Specifically, the square frame is provided with guide rods 19 at the bottom of its four corners, and the support platform 2 is provided with guide holes corresponding to the guide rods 19; in this embodiment, the guide rods 19 are set to provide precise guidance when the telescopic cylinder 14 drives the tray 1 to rise and fall.

[0030] To facilitate understanding of the above-mentioned technical solutions of this utility model, the working principle or operation method of this utility model in actual process will be described in detail below.

[0031] Working Principle: During operation, the chassis is supported by pallet 1. Positioning pins on the pallet maintain the precise position of the chassis components. The servo motor 13 drives the pulley to rotate, which in turn drives the rotating shaft 8 and limit wheel 9 on one side to rotate, which in turn drives the sleeve 12 to rotate. Through the engagement of the spline 11 and the spline groove of the sleeve 12, the rotating shaft 8 and limit wheel 9 on the other side are simultaneously rotated, controlling the servo movement of pallet 1. To adapt to different platform tracks, the double-headed telescopic cylinder 7 drives the telescopic rod to extend and retract, simultaneously adjusting the spacing of the sliding plates 5 on both sides, thereby adjusting the spacing of the two limit wheels 9, ensuring that one support platform 2 can adapt to multiple platforms. Simultaneously, the telescopic cylinder 14 drives the pallet 1 to rise and fall, adjusting its height for easy assembly and adaptation to different heights. Furthermore, the fixed plate 15 and the detachable plate 16 can be installed and removed by unscrewing screws 18, allowing for quick replacement of different detachable plates 16 and facilitating compatibility with more platforms.

[0032] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
