Description

Technical Field

[0001] This application relates to the field of automotive manufacturing auxiliary equipment technology, and in particular to an automotive door assembly transfer rack. Background Technology

[0002] In the automobile manufacturing process, the door assembly stage requires transferring doors from one workstation to another for assembly operations. Currently, most common automobile door transfer racks are fixed structures, with their dimensions and limiting methods designed for specific car models. With increasingly fierce competition in the automotive market, automakers are constantly launching new models to meet the needs of different consumers. This diversity in models leads to significant differences in door sizes and shapes. Existing fixed transfer racks cannot flexibly adapt to the transfer requirements of various doors, necessitating the design and manufacture of different transfer racks for different car models. This not only increases tooling costs for automobile manufacturers but also occupies a significant amount of warehouse space for storing these different types of transfer racks. Furthermore, in actual production, the frequent replacement of transfer racks for different car models reduces production efficiency and increases the labor intensity of workers.

[0003] To address this problem, an automotive door assembly transfer rack was invented. Utility Model Content

[0004] The purpose of this utility model is to provide an automobile door assembly transfer rack that can adapt to the transfer needs of automobile doors of different sizes through structural adjustments, improve the versatility of the transfer rack, reduce tooling costs for automobile manufacturers, increase production efficiency, and reduce the labor intensity of workers.

[0006] Optionally, the horizontal telescopic assembly further includes limiting brackets located at both ends of the scissor lift, the limiting brackets being fixed to the telescopic movable frame, the top of the scissor lift being rotatably connected to the limiting brackets, the bottom of the limiting brackets being provided with vertical slots, and the bottom of the scissor lift being rotatably connected to a movable column that can move within the vertical slots.

[0007] Optionally, the telescopic moving frame is provided with a guide mechanism to guide the horizontal sliding of the sliding rod. The guide mechanism includes a first slot seat and a second slot seat. The first slot seat and the second slot seat are respectively fixed to the two sides of the telescopic moving frame and can slide relative to each other. The bottom of the sliding rod is simultaneously slidably connected to the first slot seat and the second slot seat.

[0008] Optionally, the telescopic mobile frame includes a first traveling frame and a second traveling frame, the first traveling frame and the second traveling frame being slidably connected. A drive mechanism is provided on the telescopic mobile frame for driving it to extend and retract. The drive mechanism includes a rotating screw and a mobile frame, the mobile frame being fixedly connected to the first traveling frame, and the rotating screw being rotatably connected to the second traveling frame, with a handwheel at its end.

[0014] The present application will be further described in detail below with reference to the accompanying drawings. In the description of the present utility model, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing the present utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the present utility model.

[0015] Reference Figure 1 , Figure 2 , Figure 4 One embodiment shown is as follows: The main body of the transfer frame is composed of a horizontally extendable telescopic frame 1. Above the telescopic frame 1, a horizontal telescopic assembly 2 is connected to it. The horizontal telescopic assembly 2 has a scissor-type structure, with two sets of scissor arms 3 arranged opposite each other on the telescopic frame 1. Multiple scissor units 4 within each set of scissor arms 3 are sequentially hinged end-to-end to form a movable structure. At the hinge point of each scissor unit 4, a sliding rod 5 is installed. The bottom of these sliding rods 5 is connected to the telescopic frame 1 in a horizontally slidable manner. For example, by opening a horizontal groove on the telescopic frame 1, a slider adapted to the groove is provided at the bottom of the sliding rod 5 to achieve a sliding connection, allowing the sliding rod 5 to slide smoothly along the length direction of the telescopic frame 1. At the top of the sliding rod 5, a support assembly 6 is installed in a detachable manner via a snap-fit ​​connection. The support bracket 7 in the support assembly 6 is flat and has positioning holes 8 on its surface. The positioning pins 9 are connected to the positioning holes 8 by threaded connection. The positioning pins 9 can be installed in the appropriate positions of the positioning holes 8 according to the actual size and shape of the car door. After installation, these positioning pins 9 are distributed around the car door to limit the door. Specifically, the top of the sliding rod 5 has a slot, and the bottom of the support bracket 7 is inserted into the slot to realize the installation of the support bracket 7.

[0016] The implementation principle of the above embodiment is as follows: When it is necessary to transfer car doors of different sizes, the telescopic moving frame 1 is first operated to extend or retract. The extension or retraction of the telescopic moving frame 1 drives the horizontal telescopic component 2 connected to it to move. Since the scissor units 4 of the scissor fork 3 are hinged to each other, when the telescopic moving frame 1 extends or retracts, the scissor fork 3 expands or contracts, thereby causing the sliding rods 5 on the scissor units 4 to slide horizontally on the telescopic moving frame 1, changing the distance between adjacent sliding rods 5, and thus changing the distance between adjacent support components 6. At this time, the car door is placed on the support component 6. According to the shape and size of the car door, the positioning pins 9 are installed in the positioning holes 8 at appropriate positions on the support frame 7, so that the positioning pins 9 are distributed around the car door. The positioning pins 9 abut against the adjacent support frame 7, and this abutment force limits the car door, preventing the car door from shaking or shifting during the transfer process, thus achieving stable limiting and transfer of car doors of different sizes.

[0017] Reference Figure 4 , Figure 6 One embodiment is shown as follows: In the horizontal telescopic assembly 2, the limiting bracket 10 is located at both ends of the scissor lift 3 and is firmly connected to the telescopic moving frame 1 by welding or other fixing methods, ensuring that the limiting bracket 10 is fixed in position on the telescopic moving frame 1. The top of the scissor lift 3 is rotatably connected to the limiting bracket 10 by a pivot pin or other rotatable connector, allowing the top of the scissor lift 3 to rotate relative to the limiting bracket 10 around the pivot pin. A vertical slot 11 is provided at the bottom of the limiting bracket 10, extending vertically. A movable column 12 is rotatably connected to the bottom of the scissor lift 3 via a rotating shaft. The diameter of the movable column 12 is adapted to the width of the vertical slot 11, allowing the movable column 12 to move up and down within the vertical slot 11.

[0018] The implementation principle of the above embodiment is as follows: When the telescopic mobile frame 1 performs telescopic operation, it drives the scissor lift 3 of the horizontal telescopic assembly 2 connected to it to move. Since the top of the scissor lift 3 is rotatably connected to the limiting bracket 10, and the movable column 12 at the bottom moves within the vertical slot 11 at the bottom of the limiting bracket 10, this connection method restricts the movement trajectory of the scissor lift 3 during operation. When the scissor lift 3 expands or contracts, the movable column 12 moves up and down within the vertical slot 11, while the top of the scissor lift 3 rotates around the rotatable connection point with the limiting bracket 10, ensuring the stability of the scissor lift 3 during telescopic operation. This, in turn, ensures that the supporting assembly 6 on the horizontal telescopic assembly 2 can slide smoothly in the horizontal direction, ensuring the overall stability of the operation. This allows the transfer frame to operate reliably when adjusting the distance between adjacent supporting assemblies 6, better adapting to the transfer needs of different door sizes.

[0019] Reference Figure 1 , Figure 2 , Figure 4One embodiment shown is as follows: A guide mechanism 13 is provided on the telescopic moving frame 1, and the first slot seat 14 and the second slot seat 15 are the main components of the guide mechanism 13. The first slot seat 14 and the second slot seat 15 are fixed to both sides of the telescopic moving frame 1 by bolts or welding, and the first slot seat 14 and the second slot seat 15 are connected by a sliding connection structure such as a guide rail slider, so that they can slide relative to the telescopic moving frame 1. The bottom of the sliding rod 5 is provided with a matching slider, which is embedded in the sliding grooves of the first slot seat 14 and the second slot seat 15, realizing the sliding connection between the bottom of the sliding rod 5 and the first slot seat 14 and the second slot seat 15, and ensuring the sliding stability of the sliding rod 5 in the horizontal direction.

[0020] The implementation principle of the above embodiment is as follows: When the telescopic moving frame 1 extends or retracts, it drives the scissor lift 3 of the horizontal telescopic assembly 2 to move, thereby causing the sliding rod 5 on the scissor lift unit 4 to slide in the horizontal direction. At this time, the guide mechanism 13 plays a role. Since the bottom of the sliding rod 5 is simultaneously slidably connected to the first slot seat 14 and the second slot seat 15, the first slot seat 14 and the second slot seat 15 play a good guiding role for the horizontal sliding of the sliding rod 5. Furthermore, the first slot seat 14 and the second slot seat 15 can slide relative to the telescopic moving frame 1, which can adapt to the structural changes generated during the extension and retraction of the telescopic moving frame 1, ensuring that the sliding rod 5 can always slide stably horizontally during the entire adjustment process of the transfer frame, thereby ensuring the smooth adjustment of the distance between adjacent support assemblies 6, and improving the adaptability and operational reliability of the transfer frame to doors of different sizes.

[0021] Reference Figure 4 , Figure 5 , Figure 6 One embodiment shown is as follows: The telescopic mobile frame 1 consists of a first traveling frame 16 and a second traveling frame 17. The first traveling frame 16 and the second traveling frame 17 are slidably connected by a sliding connection structure such as a guide rail slider, allowing them to extend or retract relative to each other. A drive mechanism 18 is installed on the telescopic mobile frame 1. The mobile frame 20 is firmly connected to the first traveling frame 16 by welding or other fixing methods. One end of the rotating screw 19 is rotatably connected to the second traveling frame 17 through a rotating connecting part such as a bearing (the thread is not shown in the figure), ensuring that the rotating screw 19 can rotate smoothly on the second traveling frame 17. A handwheel 21 is provided at the other end of the rotating screw 19 for convenient manual operation by the operator.

[0022] The implementation principle of the above embodiment is as follows: When it is necessary to adjust the length of the telescopic moving frame 1 to adapt to different car door sizes, the operator turns the handwheel 21, which drives the rotating screw 19 to rotate. Since the rotating screw 19 is rotatably connected to the second traveling frame 17, and the moving frame 20 is fixedly connected to the first traveling frame 16, when the rotating screw 19 rotates, it will push the moving frame 20 and the first traveling frame 16 connected to it to slide relative to the second traveling frame 17, thereby realizing the telescopic adjustment of the telescopic moving frame 1. This drive mechanism 18 is easy to operate and can accurately control the telescopic length of the telescopic moving frame 1, thereby accurately adjusting the distance between adjacent supporting components 6 to meet the transfer needs of different car doors, improving the versatility and ease of use of the transfer frame.

[0023] Reference Figure 1 , Figure 3 One embodiment shown is as follows: At the bottom of both the first traveling frame 16 and the second traveling frame 17, traveling wheels 22 are mounted via mounting bases or other connecting components. The traveling wheels 22 are rotatably connected to the mounting bases via axles, ensuring free rotation. These traveling wheels 22 are evenly distributed at the edges of the bottom of the first traveling frame 16 and the second traveling frame 17, allowing the transfer frame to maintain balance during movement. At one end of the telescopic moving frame 1, a push rod 23 is fixedly mounted via welding or bolt connection. The push rod 23 has a rod-like structure, and its length and shape are designed for easy gripping by the operator. The connection point between the push rod 23 and the telescopic moving frame 1 is located at the end of the first traveling frame 16 or the second traveling frame 17, and the connection is firm and capable of withstanding the force applied by the operator when pushing the transfer frame.

[0024] The implementation principle of the above embodiment is as follows: When the transfer frame needs to be moved in a workshop or other work area, since both the first traveling frame 16 and the second traveling frame 17 are equipped with traveling wheels 22 at their bottoms, the operator can push the transfer frame to make the traveling wheels 22 roll on the ground. The setting of the traveling wheels 22 greatly reduces the friction between the transfer frame and the ground, allowing the transfer frame to move easily in the workshop, facilitating the transfer of car doors placed on the transfer frame to different workstations, improving the efficiency and convenience of car door transfer. Combined with the adjustable function of the telescopic mobile frame 1, the practicality of the transfer frame in the car door assembly process is further enhanced. The setting of the push rod 23 provides the operator with a convenient force application point, making the movement of the transfer frame easier and more convenient, especially in environments with limited space such as workshops, allowing the operator to flexibly adjust the position of the transfer frame and accurately transfer the car doors to the required workstations.

[0025] Reference Figure 1 , Figure 2 , Figure 4One embodiment shown is as follows: the support frame 7 has a frame structure with positioning holes 8 evenly distributed on its surface. These positioning holes 8 are arranged in various areas of the support frame 7 according to a certain spacing pattern. The bottom of the positioning post 9 is provided with external threads, which are adapted to the internal threads of the positioning holes 8. The positioning post 9 can be screwed into the positioning holes 8 at different positions on the support frame 7 by means of threaded connection, as needed.

[0026] The implementation principle of the above embodiment is as follows: Since car doors vary in size and shape, the position of the positioning post 9 needs to be adjusted according to the specific situation of the door when limiting its movement. The evenly distributed positioning holes 8 on the support frame 7 provide a wide and balanced selection for the installation of the positioning post 9. The operator can observe the positions requiring limiting around the door according to its actual size and shape, then select the corresponding positioning hole 8 and install the positioning post 9 into that hole 8 via a threaded connection. This selectable installation method of the positioning post 9 can flexibly adapt to the limiting requirements of different car doors, ensuring that the positioning post 9 is accurately distributed around the door. Through its contact with the adjacent support frame 7, it effectively limits the door movement, improving the universality and adaptability of the transfer frame for different car door models.

[0027] The working principle of this device is as follows: During operation, first rotate the handwheel 21 of the drive mechanism 18, causing the rotating screw 19 to drive the first traveling frame 16 to slide relative to the second traveling frame 17, thereby extending and retracting the telescopic moving frame 1. During this process, the scissor fork 3 of the horizontal telescopic component 2 moves with the telescopic moving frame 1. The scissor fork unit 4 hinges to extend or retract the scissor fork 3, causing the sliding rod 5 to slide horizontally within the first and second slots of the guide mechanism 13, changing the distance between adjacent support components 6. According to the door size, select a position to install the positioning post 9 in the evenly distributed positioning holes 8 of the support frame 7, and place the door on the support component 6, so that the positioning posts 9 are distributed around the door. The positioning posts 9 abut against the adjacent support frame 7 to form a limit, preventing the door from shaking. Push the push rod 23, and the traveling wheels 22 can be used to transfer the door to the target workstation, completing the transfer operation. The entire process achieves stable transfer of different doors through the cooperation of various components.

[0028] The working principle of this device has been explained through the above embodiments. These embodiments only illustrate several implementation methods of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
