Welding positioner can firmly lift and rotate large welding pieces, thus improving welding quality, speed and safety. Different welding positioners have different product structure, production conditions and actual needs. So,welding positioner has not yet formed a unified specification and standardization, which is a non-standard design and manufacturing process equipment.However, the function, requirements and composition of the basic structure of welding positioner all have the same characteristics. This article mainly introduces basic requirements for welding positioner.
Welding positioner shall be positioned reliably.
Welding positioner shall be safe and reliable during operation.
The welding positioner shall be easy to operate.
The welding positioner should act quickly.
The relevant organs of welding positioner shall be easy to adjust, repair and maintain.
The supporting points of welding positioner should be increased
Due to the increasing number of product shapes and types in the automotive industry, the structure of corresponding parts is also increasing, the types and requirements of body parts used in the welding and assembly process are not the same, so there are great differences in the structure of welding positioners.Even if the same type of welding positioner, due to the production cycle, production capacity, quality requirements and the specific production situation of the manufacturer is different, welding positioner also has certain differences.
At present, automobile manufacturers usually design welding positioner by themselves according to the characteristics of their product structure, production conditions and actual needs. Therefore, welding positioner has not yet formed a unified specification and standardization, which is a non-standard design and manufacturing process equipment.Although the welding positioner end is standardized;However, the function, requirements and composition of the basic structure of welding positioner all have the same characteristics.At present, no matter what kind of welding positioner is commonly used in automobile welding production, it should meet the following basic requirements from the perspective of actual production of welding positioner:
In the process of assembly and welding, the fixture must make the assembled parts get the correct position and reliable clamping, and during the welding can prevent the large deformation of the parts, can stabilize the relevant geometry and size of the parts after welding.
In the fixture, where the various parts of the force, should have enough strength and stiffness, and can withstand the workpiece gravity and welding process caused by the external forces in all directions.At the same time must set up the necessary security interlock protection device.
The fixture shall meet the requirements of simplified assembly and welding processes and reasonable operating procedures to ensure the position and space of welding tongs in and out and free operation of workers.
Under the premise of ensuring the strength and stiffness, it should be light and agile, positioning, clamping and loosening should be fast and labor-saving.
When the body positioning is adopted, since the body covering part is a large area and prone to deformation of the thin plate, in order to increase its rigidity and reduce welding deformation, it is necessary to increase the supporting points of welding positioner. When more supporting points are used for positioning, the adjustability of welding positioner should be considered.
