The invention discloses a robot friction stir welding supporting and guiding device. The robot friction stir welding supporting and guiding device comprises supporting plate frames. The supporting plate frames are connected through connecting rods. The inner side faces of the connecting rods are connected with heightening plates through resetting rotary shaft. Rollers are arranged on the inner side faces of the supporting plate frames and the upper surfaces of the heightening plates. Sliding blocks are supported by the upper surfaces of the rollers. The sliding blocks are arranged in the supporting plate frames. The upper ends of the sliding blocks are connected with vibration reduction tubes. The upper ends of the vibration reduction tubes penetrate through the upper surfaces of the corresponding supporting plate frames. The interiors of the vibration reduction tubes are connected with vibration reduction rods through compression springs. The robot friction stir welding supporting andguiding device can support and guide a robot to conduct friction stir welding. The problems that vibration is generated during friction stir welding and the motion precision of the robot is reduced in the welding process due to the characteristics of high flexibility of the robot are avoided. Moreover, the robot friction stir welding supporting and guiding device can conduct further extrusion ona welding part to be welded and ensure the welding stability of the welding part.
Description
technical field [0001] The invention relates to the technical field of robot friction stir welding, in particular to a robot friction stir welding supporting and guiding device. Background technique [0002] Robot friction stir welding is a kind of equipment for welding by heat energy generated by friction. When welding, a cylinder or other shaped stirring needle is inserted into the joint of the workpiece, and the high-speed rotation of the welding head makes it weld The material of the workpiece is rubbed, so that the temperature of the material at the connection part rises and softens, and the purpose of material welding is completed. [0003] However, during the use of the existing robot friction stir welding, vibration will be generated. Due to the high flexibility of the robot, the running accuracy of the robot will be affected, which is not conducive to ensuring the quality of welding. Therefore, in order to solve the above problems, it is necessary to study and desig...
