Description

Technical Field

[0001] The utility model relates to the technical field of punching devices, in particular to a vehicle body plate punching device for manufacturing semi-trailers. Background Art

[0002] In semi-trailer manufacturing, punching holes in car body panels is a critical process. Currently, due to the large size of car body panels, some small factories typically rely on manual labor. Specifically, workers first lay the panels flat before drilling using punching equipment. Throughout the entire drilling process, the panel's position must be frequently adjusted to accommodate the various punching locations.

[0003] However, this traditional operation method has some drawbacks. On the one hand, its low degree of automation and heavy reliance on manual operation are not only inefficient but also difficult to ensure the accuracy and consistency of punching. On the other hand, due to the large size and heavy weight of the semi-trailer body panels, manual movement is extremely inconvenient, which is not only time-consuming and labor-intensive, but also increases the labor intensity and safety risks of workers. In order to improve the difficulty of manual handling, some companies have introduced conveyors to push the body panels into the punching area through the conveyor. However, this improvement method has brought new problems. When the body panels are placed on the rollers of the conveyor for punching, due to the rolling characteristics of the rollers and the limited friction between the body panels and the rollers, the body panels are prone to shaking and offsetting during the punching process. This leads to deviations in the punching position. Utility Model Content

[0004] The purpose of the utility model is to make up for the deficiencies of the prior art and to provide a vehicle body plate punching device for manufacturing a semi-trailer.

A number of No. 3 cylinders 9 are installed on the outer surface of the frame of the roller conveyor 1 at equal intervals, and the output end of the No. 3 cylinder 9 is connected to a splint 10.

[0027] By placing the car panel to be punched on multiple conveying rollers of the roller conveyor 1, the roller conveyor 1 is driven by a servo motor, so that the roller conveyor 1 can convey the car panel to the bottom of the punching assembly 3. When the car panel moves to the punching position, the output end of the No. 3 cylinder 9 is started to drive the splint 10 to move toward the car panel.
