Description

Technical Field

[0001] This utility model belongs to the field of vehicle door assembly and transfer technology, and more specifically, relates to a flexible vehicle door assembly and transfer tooling. Background Technology

[0002] In automobile manufacturing, door assembly is a key process in the final assembly stage, and its process route and equipment configuration directly affect the overall vehicle production efficiency and assembly quality. For mature, high-volume models, the mainstream production method currently adopts a "door pre-assembly followed by final assembly" process. This involves disassembling the doors before the painted body enters the final assembly workshop and transferring them to a dedicated automated door pre-assembly line. On this line, various interior components (such as window regulators, door locks, speakers, and sensors) are assembled. The assembled doors are then transferred to the final assembly station for precise docking with the body. This model offers advantages such as high automation, tight cycle time, and high assembly precision, making it suitable for single-model, high-volume production scenarios. However, in the prototype production stage or when facing the demand for multi-variety, small-batch production, the application of traditional door pre-assembly lines reveals a series of limitations. Specifically, door pre-assembly lines typically require high initial investment costs, have long engineering and equipment modification cycles, and occupy a large area. They are also difficult to flexibly adapt to rapid switching between different models, leading to resource waste and inefficiency.

[0003] To address these challenges, some existing technologies have attempted to improve the adaptability of door assembly tooling through modular design, universal fixture development, and the application of flexible conveyor systems. For example, some companies are trying to use adjustable positioning devices and quick-change fixture structures to achieve compatibility and fixation for doors of different car models; other solutions introduce flexible logistics methods such as AGVs (Automated Guided Vehicles) or roller conveyors to replace traditional fixed conveyor lines, improving the spatial flexibility and path variability of door assembly lines. In addition, some research has proposed tooling platforms based on standardized interfaces, which, through modular layout of key assembly points, enable the same tooling platform to support the assembly needs of multiple door structures.

[0004] Although existing technologies have made some progress in flexibility, they are still limited by design concepts and technical implementation methods, and cannot fundamentally overcome the inherent rigidity of traditional vehicle door assembly lines. First, most existing assembly lines still rely on fixed workstations and specialized equipment. Structural adjustments often require redesigning tooling structures or even modifying civil engineering foundations, resulting in long equipment change cycles and high implementation difficulty. Second, while flexible logistics systems improve the flexibility of material handling, they lack a high degree of integration with assembly processes, failing to form a truly integrated "assembly-transfer" solution, leading to low overall system coordination efficiency.

It should be understood that the specific embodiments described herein are only for explaining the present utility model and are not intended to limit the present utility model. Furthermore, the technical features involved in the various embodiments of the present utility model described below can be combined with each other as long as they do not conflict with each other.

[0022] like Figures 1 to 5 As shown, one embodiment of this utility model provides a flexible automotive door assembly and transfer fixture, including: a frame 1 and a clamping assembly 2; the frame 1 includes: a base frame 11, two support beams 15 symmetrically fixed at the upper ends of two longitudinal beams of the base frame 11, and moving wheels 13 located at the four corners of the base frame 11; the clamping assembly 2 includes: a plurality of clamps 26 detachably connected to the two support beams 15 respectively, and two clamps 212 on one support beam 15 that are mirror-symmetrical about the axis of the support beam 15 and are respectively located above the two support beams 15 and facing each other. This utility model's assembly and transfer fixture, through its flexible and adjustable structure, effectively overcomes the shortcomings of traditional car door assembly lines in adapting to multiple car models while reducing investment costs, shortening construction and modification cycles, and reducing floor space. It achieves efficient and flexible assembly and transfer functions under conditions of multi-variety, small-batch, and prototype production, improving the efficiency and quality of car door assembly in the automobile manufacturing process. Specifically, the frame 1 effectively and stably supports the clamping assembly 2 and the car door, ensuring overall structural stability and reliability, and providing good mobility and flexibility for rapid transfer between different workstations and adaptation to various production layout requirements. Furthermore, the modular and symmetrical design of the clamping assembly 2 allows for flexible adjustment of the position and number of clamps according to the structural characteristics of different car door models, achieving firm clamping of the door and meeting the diverse door assembly needs in prototype production and multi-variety, small-batch production.

[0023] It should be noted that the clamping device 26 is a commonly used clamp in the existing machinery industry. In this embodiment, it can be used to clamp the sheet metal on both sides of the door assembly during the disassembly and transfer of automobile doors. Of course, in other embodiments, other devices can also be used. No specific limitation is made here, but these solutions are all within the protection scope of this utility model.

[0024] like Figure 1 , Figure 2 and Figure 5 As shown, the frame 1 further includes: a mounting base 12, a first support base 14, a reinforcing plate 16, and a handrail 17; the moving wheels 13 are detachably connected to the mounting base 12, and four mounting bases 12 are fixedly installed at the four corners of the bottom end of the base frame 11; multiple first support bases 14 are fixedly fixedly on the upper ends of two crossbeams of the base frame 11 in a mirror-symmetrical manner about the axis of the base frame 11, and their upper surfaces are pre-set with a number of connection holes; the reinforcing plate 16 is fixedly installed on the side of the support beam 15 away from the base frame 11, and is fixedly connected to the longitudinal beam of the base frame 11 connected to the support beam 15; the handrail 17 is fixedly connected to the longitudinal beam on one side of the base frame 11. It is understandable that, in practical applications, by adding the mounting base 12 between the moving wheel 13 and the base frame 11, the structural strength and load-bearing capacity of the mounting part of the moving wheel 13 can be effectively enhanced, and the problem of local stress concentration can be effectively dispersed, thereby improving the stability and service life of the overall tooling structure. At the same time, the reinforcing plate 16 effectively enhances the bending resistance and structural strength of the support beam, ensuring the stability and safety during the assembly of the car door. In addition, the armrest 17 not only facilitates safe handling and positioning operations for operators, but also further enhances the human-machine interface friendliness and on-site applicability of the entire tooling.

[0025] In an optional embodiment, the handrail 17 is made of rust-proof steel pipe bent into a U-shape to push the overall tooling, thereby facilitating the transfer of the tooling and avoiding potential injury to the operator.

[0026] Furthermore, the base frame 11 is a square frame welded from several square steel bars to form a stable support skeleton.

[0027] Furthermore, the two movable wheels 13 adjacent to the handrail 17 are universal wheels with brakes, and the two movable wheels 13 away from the handrail 17 are directional wheels, in order to reduce the overall cost while satisfying the flexible movement of the tooling and the fixation of the operation process.

[0028] Furthermore, the surface of the support beam 15 is pre-set with a first mounting seat 15a, a second mounting seat 15b, and a third mounting seat 15c; the two first mounting seats 15a are symmetrically arranged on both sides of the support beam 15 about the axis of the support beam 15, and are parallel to the crossbeam of the base frame 11; the two second mounting seats 15b are symmetrically arranged on both sides of the support beam 15 about the axis of the support beam 15, are parallel to the crossbeam of the base frame 11, and are located above the first mounting seats 15a; the third mounting seat 15c is located on the side of the support beam 15 away from the base frame 11; the surfaces of the first mounting seats 15a, the second mounting seats 15b, and the third mounting seat 15c are all pre-set with a plurality of connecting holes, which are used to stably connect the clamping assembly 2 components while conveniently adjusting their positions to improve adaptability to various types of car doors.

[0029] like Figures 1 to 5 As shown, the clamping assembly 2 is used to clamp and fix the door assembly on the tooling. The clamping assembly 2 also includes: a first support block 21, a second support seat 22, a third support seat 23, a first pad block 24, a second pad block 25, a limiting bracket 27, a third pad block 28, a fourth pad block 29, a fifth pad block 210, and a clamping device bracket 211. The first support block 21 corresponds one-to-one with the first support seat 14. It is detachably mounted on the upper end of the first support seat 14, and a V-shaped limiting groove is provided in the middle of its upper end along the direction of the crossbeam of the base frame 11. Two second support seats 22 are respectively disposed between the clamping device 26 and the first mounting seat 15a on one of the support beams 15, and each second support seat 22 is detachably connected to the first mounting seat 15a and the clamping device 26; and, in the direction of the crossbeam of the base frame 11, the surface of the first mounting seat 15a corresponding to the clamping head of the clamping device 26 is provided with the first pad 24. Two third support seats 23 are respectively disposed between the clamping device 26 on another support beam 15 and the first mounting seat 15a. Each third support seat 23 is detachably connected to the support beam 15 and the first mounting seat 15a. Meanwhile, in the direction of the crossbeam of the base frame 11, the surface of the first mounting seat 15a corresponding to the clamping head of the clamping device 26 is provided with the second pad 25. The fifth pad 210 corresponds one-to-one with the second mounting base 15b, and is detachably disposed on the side of the second mounting base 15b away from the support beam 15; one side of each of the two limiting brackets 27 is detachably connected to the two fifth pads 210 on one of the support beams 15 and is mirror-symmetrical about the axis of the support beam 15; the limiting bracket 27 is an L-shaped bracket, with its inner side facing the middle of the base frame 11 and the third pad 28 and the fourth pad 29 respectively provided on its inner two sides; the clamping bracket 211 is an L-shaped bracket, with one side detachably connected to the clamping device 212, and the other side having multiple sets of through holes adapted to the connecting holes of the third mounting base 15c and detachably connected to the third mounting base 15c.

[0030] It should be noted that in this embodiment, different second support seats 22 and third support seats 23 are provided between the clamping device 26 on different support beams 15 and the first mounting seat 15a, thereby adjusting the distance between the clamping device 26 and the corresponding first mounting seat 15a, so that the left and right doors can be clamped symmetrically on both sides of the two support beams 15 according to the thickness of the door, thereby improving the clamping accuracy.

[0031] It should be noted that the first support block 21, the first pad block 24, the second pad block 25, the third pad block 28, the fourth pad block 29 and the fifth pad block 210 are all made of polyurethane to effectively prevent damage to the paint on the car door surface. Of course, other devices may be used in other embodiments, which are not specifically limited here, but these solutions are all within the protection scope of this utility model.

[0032] Further, the clamp 212 includes: a mounting plate 212a, a push-pull quick clamp 212b, a connecting plate 212c, and a limiting slot 212d; the mounting plate 212a is detachably connected to the clamp bracket 211 and the push-pull quick clamp 212b respectively, and has multiple sets of mounting holes matching the push-pull quick clamp 212b along the crossbeam direction of the base frame 11; the middle part of one side of the connecting plate 212c is fixedly connected to one end of the push-pull quick clamp 212b, and has two oblong holes mirror-symmetrically arranged on it along its axis; the limiting slot 212d is detachably connected to the connecting plate 212c through its connecting hole and the oblong hole, and its connection position with the connecting plate 212c is adjusted through the oblong hole.

[0033] It should be noted that the push-pull quick clamp 212b is a commonly used clamp in the existing machinery industry. In this embodiment, it can be used to adjust the opening distance between the limiting slots 212d on the two connecting plates 212c during the disassembly and transfer of automobile doors. Of course, in other embodiments, other devices can also be used, which are not specifically limited here, but these solutions are all within the protection scope of this utility model.

[0034] Understandably, through the above design, a flexible contact method is adopted in the contact area between the clamping component 2 and the car door, effectively avoiding surface damage such as scratches and indentations caused to the car door paint by traditional rigid clamping structures during the clamping process. This significantly improves product protection capabilities during assembly, making it particularly suitable for high-end models or production scenarios with high requirements for appearance quality during the trial production stage. Simultaneously, through the cooperation between the third mounting base 15c and the clamping bracket 211, the clamping device 212 can be flexibly adjusted in the Z-direction, i.e., the vertical direction, thereby adapting to car door structures with different height references. Furthermore, the mounting plate 212a inside the clamping device 212 provides support for the push-pull quick clamp 212b. The positioning and adjustment of the limiting slot 212d in the X-direction (door width direction) by the push-pull quick clamp 212b allows the clamping system to precisely match the contours of doors of different widths. Furthermore, the waist-shaped hole structure on the connecting plate 212c allows for fine-tuning of the limiting slot 212d in the Y-direction (door thickness direction), achieving precise multi-degree-of-freedom adaptation in three-dimensional space and ultimately enabling efficient and safe clamping of doors of different specifications. In addition, by symmetrically arranging various key components on the base frame 11 and the support beam 15, the left and right doors can be simultaneously assembled and transferred on the same tooling platform, significantly improving equipment utilization and production efficiency.

[0035] The working principle of this utility model is as follows: After the painted body assembly enters the final assembly workshop, the left and right door assemblies are removed from the vehicle body, and the bottom sheet metal parts of the left and right door assemblies are placed in the V-shaped limiting groove of the first support block 21. The middle door outer sheet metal can simultaneously fit with the first pad block 24, the second pad block 25, the third pad block 28, the fourth pad block 29, and the fifth pad block 210. By operating the handle of the push-pull quick clamp 212b, the limiting slot 212d is pushed forward to lock the upper sheet metal of the door, thus limiting the overall door position. Then, the clamping device 26 is operated to clamp the sheet metal in the middle of the car door, completing the fixation of the left and right car door assemblies. After that, the door lock, sealing strip, car door wiring harness, rearview mirror assembly, glass guide rail, regulator, glass, waterproof membrane, door light, car door speaker, window regulator switch, inward opening handle, car door trim panel and other components can be installed to the corresponding positions of the car door in sequence. The left and right car door assemblies are assembled on the tooling. The brake of the moving wheel 13 is released and the tooling can be easily moved to the car door assembly station through the handle 17 to assemble the car door with the car body.

[0036] It should be noted that if the embodiments of this utility model involve directional indicators (such as up, down, left, right, front, back, etc.), the directional indicators are only used to explain the relative positional relationship and movement of the components in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicators will also change accordingly.

Therefore, features defined with "first" or "second" may explicitly or implicitly include at least one of those features.
