Description

Technical Field

[0001] The utility model belongs to the technical field of industrial robot welding fixation, and relates to a welding fixation device for manufacturing industrial robots. Background Art

[0002] When existing industrial robots perform welding operations, if they cannot effectively fix relevant components, a series of disadvantages will arise. The welding quality will be affected because unstable components may cause discontinuous and uneven welds, thereby affecting the welding strength and tightness. The instability during the welding process will increase the positioning difficulty of the robot, resulting in the robot needing to be adjusted more frequently, thus reducing production efficiency. The unfixed components may also pose a risk of collision between the robot and the components, increasing the possibility of equipment damage and safety accidents.

[0003] The root cause of these disadvantages is that the positioning and fixation of components during the welding process are key factors to ensure welding quality, and robot welding relies on precise positioning and stable workpieces. If the workpiece moves or vibrates during the welding process, it is difficult for the robot to perform precise control, thus affecting the welding effect. Conventional countermeasures include using more complex fixture systems to fix components. The drawback of these methods is that complex fixture systems may require a long preparation time, affecting production flexibility. Therefore, there is an urgent need for a welding fixation device for manufacturing industrial robots to solve the above problems. Summary of the Utility Model
