[0002] Automated assembly of automotive parts refers to the use of automated technologies and equipment to complete the assembly of automotive parts during the automotive manufacturing process.

[0003] However, in the existing technology, during the assembly process, the movement of equipment with low degrees of freedom in space is restricted, making it difficult to adapt to parts with different shapes, positions or orientations. Especially when facing complex or multi-angle assembly tasks, it is difficult to complete the required fine adjustments and posture changes. If manual intervention or additional fixtures and jigs are required to achieve positioning and adjustment, the efficiency and advantages of automated production will be weakened. Summary of the Invention

[0004] The purpose of this invention is to solve the problem that existing equipment with low degrees of freedom has limited movement in space and is difficult to adapt to parts with different shapes, positions or orientations, and to propose an automated assembly production line for automotive parts.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: an automated assembly production line for automotive parts, including a base, a robotic arm rotatably connected to the middle of the base, a clamp fixedly connected to one end of the robotic arm, and a rotating mechanism installed at the bottom of the base.

[0006] The rotating mechanism includes a base plate, a first cylinder is symmetrically fixedly connected to the top of the base plate, a lifting plate is fixedly connected to the top of the first cylinder, a central rod is rotatably connected to the middle of the lifting plate, a rotating plate is fixedly connected to the top of the central rod, a gear is fixedly connected to the outer surface of the bottom end of the rotating plate, a rack is meshed with one side of the gear, a guide block is slidably connected to the outer surface of the rack, and the guide block is fixedly connected to the lifting plate.

[0013] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0014] 1. In this utility model, the precise positioning and stable clamping of the parts to be assembled are achieved through the coordinated cooperation of the robotic arm and the fixture. The rack is driven to move linearly by the second cylinder, which drives the gear meshing with it to rotate, thereby achieving the synchronous rotation of the central rod and the rotating plate, and finally driving the base to rotate, thus completing the adjustment of the fixture posture.

[0021] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0022] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0023] Example 1: As shown in Figures 1-4, this utility model provides an automated assembly production line for automotive parts, including a base 2, a robotic arm 3 rotatably connected to the middle of the base 2, a clamp 4 fixedly connected to one end of the robotic arm 3, and a rotating mechanism 1 installed at the bottom of the base 2.

[0024] The rotating mechanism 1 includes a base plate 11, a first cylinder 12 is symmetrically fixedly connected to the top of the base plate 11, a lifting plate 13 is fixedly connected to the top of the first cylinder 12, a central rod 17 is rotatably connected to the middle of the lifting plate 13, a rotating plate 16 is fixedly connected to the top of the central rod 17, a gear 171 is fixedly connected to the outer surface of the bottom end of the rotating plate 16, a rack 141 is meshed with one side of the gear 171, a guide block 131 is slidably connected to the outer surface of the rack 141, and the guide block 131 is fixedly connected to the lifting plate 13.

[0025] The specific setup and function of this embodiment will be described in detail below. During the assembly of automotive parts, in order to ensure assembly accuracy and work efficiency, a fixture 4 is used to stably hold the parts to be assembled. Throughout the assembly process, the position of the fixture 4 is adjusted by the robotic arm 3 to achieve precise positioning of the assembled parts.

[0026] After the fixture 4 completes the initial clamping, the assembly system will drive the second cylinder 14 according to the actual assembly requirements of the parts. During the operation of the piston rod of the second cylinder 14, it will drive the rack 141 connected to it to move linearly. Since the rack 141 meshes with the gear 171, when the rack 141 moves, it will apply a meshing force to the gear 171, thereby driving the gear 171 to rotate along its axis.

[0027] The rotation of gear 171 further drives the coaxially connected central rod 17 to rotate synchronously. Since the central rod 17 is structurally fixedly connected to the rotating plate 16, the rotation of the central rod 17 will directly cause the rotating plate 16 to produce angular displacement. The rotation of the rotating plate 16, in turn, forms a linkage with the base 2, so the base 2 will rotate accordingly, realizing the posture adjustment of the overall fixture 4.

[0028] By rotating the base 2, not only can the direction of the fixture 4 be changed, but the posture and position of the parts held by the fixture 4 in space can also be further corrected. In this way, it can be ensured that the relative position and angle of the parts meet the set requirements before entering the next process or assembly interface, thereby greatly improving the accuracy and automation level of the assembly process.

[0029] Example 2: As shown in Figures 2 and 3, a fixed plate 19 is fixedly connected to the top of the lifting plate 13, and a threaded rod 191 is threadedly connected to the upper part of the fixed plate 19. A limiting plate 161 is fixedly connected to the bottom of the lifting plate 13. The limiting plate 161 abuts against the threaded rod 191. A second cylinder 14 is fixedly connected to one end of the bottom of the lifting plate 13, and the output end of the second cylinder 14 is fixedly connected to a rack 141. Multiple support rollers 15 are fixedly connected to the top of the lifting plate 13, and the support rollers 15 abut against the rotating plate 16. Multiple telescopic rods 18 are fixedly connected to the top of the base plate 11, and the top of the telescopic rods 18 is fixedly connected to the bottom of the lifting plate 13.

[0030] The overall effect of this embodiment is that, during its movement, the rack 141 is restricted by the guide block 131, thereby ensuring that the rack 141 moves linearly and horizontally under the drive of the second cylinder 14, without any vertical or skewed movement. This guiding structure not only improves the stability of the rack 141's movement but also ensures that its meshing with the gear 171 remains stable and reliable, avoiding problems such as gear 171 disengagement or poor meshing caused by deviation, thereby improving the overall efficiency and lifespan of the transmission system.

[0031] With the cooperation of gear 171 and center rod 17, the rotating plate 16 can be driven to rotate smoothly. In order to prevent the rotating plate 16 from shaking or tilting due to uneven force during rotation, a support roller 15 is provided in the design to provide reliable support for the rotating plate 16, so that it always stays on the set rotation track and plane during rotation, thereby ensuring the accurate operation of subsequent structures.

[0032] As the rotating plate 16 rotates, the limiting plate 161 also moves synchronously. During this process, the range of motion of the limiting plate 161 is jointly limited by the fixed plate 19 and the threaded rod 191. The fixed plate 19 serves as the limiting base, providing rigid constraints, while the threaded rod 191 can adjust the limiting range according to specific needs, achieving fine-tuning control of the rotation angle, thereby improving the accuracy and adaptability of the entire mechanism.

[0033] In addition, to adjust for different height requirements under different working conditions, the system is equipped with a first cylinder 12 and its connected telescopic rod 18. The first cylinder 12 drives the lifting plate 13 to rise and fall vertically, while the telescopic rod 18 provides stable support during the lifting process, effectively preventing swaying and deviation.

[0034] The device's operation and working principle are as follows: During automotive parts assembly, the fixture 4 is used to clamp the parts, and the position of the fixture 4 is adjusted by the robotic arm 3. During assembly, the second cylinder 14 drives the rack 141 to move. As the rack 141 moves, it applies a force to the gear 171, causing the gear 171 and its connected central rod 17 to rotate. Driven by the rotation of the central rod 17, the rotating plate 16 rotates, which in turn drives the base 2 to rotate, thereby adjusting the position of the parts clamped by the fixture 4 for precise assembly.

[0035] During its movement, the rack 141 is restricted by the guide block 131 to ensure that it moves horizontally under the drive of the second cylinder 14 and can stably mesh with the gear 171 to avoid meshing deviation.

[0036] During the rotation of the rotating plate 16 driven by the gear 171 and the central rod 17, the support roller 15 provides support to prevent the rotating plate 16 from tilting and ensure its smooth rotation. At the same time, the rotation of the rotating plate 16 also drives the limiting plate 161 to move synchronously, and the fixing plate 19 and the threaded rod 191 play a limiting role in this process.

[0037] In addition, by using the drive of the first cylinder 12 in conjunction with the support of the telescopic rod 18, the height of the lifting plate 13 can be controlled, further improving the degree of freedom of position adjustment during assembly.

[0038] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
