Description

Technical Field

[0001] This utility model relates to the field of pre-fixing technology in automobile production lines, specifically to an automatic pre-fastening and bending mechanism for side panels. Background Technology

[0002] Modern vehicles have large side panels. In actual production, vehicle side panels are usually transported via EMS or other means. After transport, a robotic arm picks up the side panel from the EMS equipment. During the installation of the vehicle side panel, it is usually necessary to pre-position it before further installation. In the existing technology, there are buckles around the vehicle side panel. Pre-positioning is achieved by bending the buckles. If a person manually enters to bend the buckles during the robotic arm loading process, human and machine safety cannot be guaranteed. It is time-consuming, labor-intensive, has low accuracy, and is prone to damage to the side panel. Utility Model Content

[0003] The main technical problem to be solved by this utility model is to provide an automatic pre-fastening bending mechanism for the side panel. This mechanism can bend the fasteners of the car side panel to achieve pre-positioning, improve the efficiency and accuracy of bending, and avoid the safety problems caused by manual operation.

[0004] To solve the above-mentioned technical problems, this utility model provides the following technical solution: An automatic pre-fastening bending mechanism for side panels includes a mounting frame. A first cylinder is fixedly mounted on the side of the mounting frame, and a clamping assembly is connected to the power output end of the first cylinder. A second cylinder is disposed above the mounting frame, and a first connecting rod is connected to the power output end of the second cylinder. The first connecting rod is drivenly connected to a second connecting rod. Both the first and second connecting rods are rotatably connected within the mounting frame. A fastening clamping block is disposed at one end of the second connecting rod.

[0005] The following are further optimizations of the above technical solution by this utility model: The clamping assembly includes a pressure arm, and a pressure block is provided at one end of the pressure arm.

[0006] Further optimization: A support block for supporting the vehicle side panel is provided below the mounting bracket, and the support block is located below the second connecting rod.

[0007] Further optimization: The mounting bracket is provided with a first connecting shaft and a second connecting shaft, the first connecting rod is rotatably connected to the first connecting shaft, and the second connecting rod is rotatably connected to the second connecting shaft.

[0008] This utility model adopts the above-mentioned technical solution, which is ingenious in conception and reasonable in structure. By forming opposite forces through the support block and the pressure block, the vehicle side panel and the vehicle floor panel are pre-fixed. Then, through the transmission connection of the first connecting rod and the second connecting rod, the buckle clamping block bends the buckle. The whole process does not require manual operation and can be achieved entirely by robot operation, which greatly improves the bending efficiency and accuracy of the buckle and avoids the errors and safety problems caused by manual operation.

[0009] The present invention will be further described below with reference to the accompanying drawings and embodiments. Attached Figure Description

[0012] like Figure 1-2 As shown: An automatic pre-fastening bending mechanism for side panels includes a mounting frame 1. A first cylinder 2 is fixedly mounted on the side of the mounting frame 1, and a clamping assembly is connected to the power output end of the first cylinder 2. A second cylinder 4 is arranged above the mounting frame 1, and a first connecting rod 5 is connected to the power output end of the second cylinder 4. The first connecting rod 5 is drivenly connected to a second connecting rod 6. Both the first connecting rod 5 and the second connecting rod 6 are rotatably connected within the mounting frame 1. A fastening clamping block 7 is provided at one end of the second connecting rod 6.

[0013] The clamping assembly includes a pressure arm 3, and a pressure block 8 is provided at one end of the pressure arm 3.

[0014] In this embodiment, the pressure block 8 is used to clamp the vehicle side panel and the vehicle floor panel.

[0015] A support block 9 for supporting the vehicle side panel is provided below the mounting bracket 1, and the support block 9 is located below the second connecting rod 6.

[0016] In use, first place the vehicle side panel in the corresponding position, and support block 9 presses against the outside of the vehicle side panel to align the vehicle side panel and the vehicle floor panel. At this time, the buckle to be bent is pressed against the outside of the vehicle side panel by support block 9. Then, start the first cylinder 2. The power output end of the first cylinder 2 drives the pressure arm 3 to rotate. The pressure block 8 presses against the inside of the vehicle floor panel under the action of the pressure arm 3. At this time, support block 9 and pressure block 8 form opposite forces, thereby achieving pre-fixation of the vehicle side panel and the vehicle floor panel for convenient use.

[0017] The mounting bracket 1 is provided with a first connecting shaft 10 and a second connecting shaft 11. A first connecting rod 5 is rotatably connected to the first connecting shaft 10, and a second connecting rod 6 is rotatably connected to the second connecting shaft 11.

[0018] When in use, the second cylinder 4 is started. The power output end of the second cylinder 4 drives the first connecting rod 5 to rotate around the first connecting shaft 10. Since the first connecting rod 5 and the second connecting rod 6 are connected by transmission, the second connecting rod 6 rotates around the second connecting shaft 11, thereby driving the latch clamping block 7 to press down. During the pressing process, it touches the latch to be bent, thereby bending the latch to achieve pre-fixation of the vehicle side panel and the vehicle floor panel, which is convenient for use.

[0019] For those skilled in the art, any changes, modifications, substitutions, and variations made to the implementation methods without departing from the principles and spirit of this utility model, based on the teachings of this utility model, still fall within the protection scope of this utility model.
