Description

Technical Field

[0001] The present invention relates to the technical field of numerical control machine tools, and more specifically, to an integrated processing device for automobile door panel plastic parts. Background Art

[0002] In the automotive manufacturing industry, the processing of door panel plastic parts is a crucial link. Traditional processing methods usually involve multiple independent processes, such as welding and screw tightening, which are often carried out on different equipment or workbenches, resulting in low production efficiency and increased production costs; welding is an indispensable step in the processing of automobile door panel plastic parts. Through welding, the various parts of the plastic parts can be firmly connected together to form a complete door panel structure. However, traditional welding equipment is often only able to perform a single welding operation and cannot be integrated with other processing processes, thus limiting the improvement of production efficiency; at the same time, screw tightening is also an indispensable part of the processing of automobile door panel plastic parts. After welding is completed, screws are usually required to fix the plastic parts to other components (such as metal frames or interior panels). Traditional screw tightening operations are usually completed manually, which is not only inefficient but also prone to errors, affecting product quality.

[0003] In order to improve production efficiency and reduce costs, the market urgently needs an integrated processing equipment for automobile door panel plastic parts that can perform welding and screw fastening at the same time. This equipment should be able to integrate the two processes of welding and screw fastening to achieve automated production, thereby improving production efficiency and reducing the error rate of manual operation.

[0004] However, there is no equipment on the market that can meet this demand. Most of the existing equipment can only perform a single welding or screw fastening operation, and cannot achieve the integration and automated production of the two processes. Therefore, the development of an integrated processing equipment for automobile door panel plastic parts that can perform welding and screw fastening at the same time is of great significance to improving the production efficiency and quality of the automobile manufacturing industry.

[0043] like Figure 1-7 As shown, an outer frame 7 is provided on the base 1, and the outer frame 7 covers the first frame 11 and the second frame 12. An electric control box 71 is installed on the side of the outer frame 7, and an exhaust fan 72 for exhaust and a tower light 73 for displaying the operating status of the equipment are installed on the upper end of the outer frame 7. The exhaust fan 72 is connected to the factory's ventilation duct, and a pneumatic safety door 74 is installed at the front end of the outer frame 7. An operation touch screen is installed at the front end of the outer frame 7.

[0044] Start the equipment: First, the operator starts the equipment by operating the touch screen. After receiving the command, the electric control box 71 supplies power to each motor, cylinder and other actuators.

[0045] Adjust the fixing column 51: Before operation, the operator needs to adjust the extension length of the fixing column 51 in the threaded sleeve 52 according to the size of the plastic part to be processed by screwing it to ensure that the plastic part can be effectively clamped.
