TTM is a machinery and equipment manufacturing factory with rich experience in robotic welding fixtures，here we want to share What is the Key Design Points of Robot Welding Fixtures in Automobile Production Line？
 
According to statistics, 60%-70% of the workload of the welding production line falls on the clamping and auxiliary links, and all the clamping needs to be completed on the fixture, so the fixture occupies an inestimable position in the entire automobile welding. Today, I would like to share an article with you, analyzing the design points of the robot welding fixture on the automobile production line.
 
Key points of welding fixture design
Automobile welding process The automobile welding process is a combination process from parts to assemblies. Each combination process is independent of each other and does not interfere with each other, but it has a sequential relationship between the past and the future. The existence of this relationship ensures the accuracy of the automobile welding process, and each combination process will affect the assembly welding accuracy. Therefore, each welding assembly fixture of the body must establish a unified and continuous positioning reference
 
Robots In the field of automobile design and manufacturing, in order to reduce labor and improve work efficiency, robots are widely used. Facts have proved that due to the lack of flexibility of the robot, the welding quality is difficult to be guaranteed. In order to solve the troubles caused by lack of flexibility and judgment ability, the designer must not only ensure the reliability of the fixture, but also leave enough space and path for the welding torch to provide a comfortable welding posture for the robot; in addition, the fixture must be lifted The accuracy ensures that the robot executes the established procedures and reduces welding errors.

Safety From the perspective of workers, the purpose of welding jig design is to reduce labor on the basis of ensuring personal and equipment safety. Therefore, the design of the welding jig satisfies ergonomics and at the same time facilitates the assembly and removal of parts and components in a safe environment for workers.
 
Composition of the welding fixture
Clamp body The clamp body is composed of two devices: positioning and clamping. It serves as the basic unit of the fixture for hoisting, three-coordinate detection and calibration. Check the flatness of the working surface to ensure the accuracy of the positioning mechanism by improving its accuracy when processing the clamp body. When designing the clamp body, the actual assembly and measurement should be taken as the ultimate goal, to ensure that the design strength of the clamp body matches the height of the space, and to minimize the self-weight of the clamp body. For example, according to the shape of the workpiece, follow the welding principle, choose a single beam or frame structure for the purpose of reducing the weight of the fixture, facilitating pipeline connection, and providing enough welding space for the robot.
Above is all we want to talk in this article,thanks for you reading!
