S7 Rear Floor Automatic Welding Line

S7 rear floor automatic welding line

Case highlights: 1. Mixed production of three types of floor assemblies, including S7 rear floor, M432 front and rear floors, ensures flexible switching of fixtures; 10 robots and 3 sliding tables.

Automobile body welding production line is one of the important production lines in the production process of cars, minibuses and other models. From the perspective of the development history of the automobile industry, the body welding line has experienced manual welding lines in the 1950s and 1960s to automated rigid welding in the 1970s. Assembly line - the stage of robotic flexible welding assembly line after the 1980s.

Accompanying trolley through production line

The typical form of this production line is shown in Figure 4. It generally adopts the same trolley-type fixtures in different quantities, and is driven by a chain to a predetermined station. After manual feeding and manual welding, each car body is placed on the same fixture and different working stations. Complete the assembly. This form of production line has low production efficiency, high labor intensity, single-species special-line production, and the accuracy and quality of products are not easy to guarantee. It is a commonly used production form in the early days and is generally suitable for small batch production.

Analysis on the structure and working principle of the transmission device of the automobile welding production line

The following takes the transmission device of the automobile side panel assembly line as an example to analyze its structure and working principle in detail

The transmission device of the side panel assembly line of a certain vehicle type adopts a four-station reciprocating rod device, which can realize horizontal and vertical movement. The structure and function analysis of each sub-assembly is as follows:

Drive unit

Working principle: The motor drives the two gears to rotate through the coupling, and the two gears respectively drive the moving skateboard to move through the parallel racks meshing with it, thereby driving the body side panel mounted on the moving skateboard to move horizontally.
