Description

Technical Field

[0001] The utility model belongs to the technical field of welding robots, and particularly relates to a welding robot with a height adjusting device. Background Technique

[0002] According to the definition of industrial robots belonging to standard welding robots by the International Organization for Standardization (ISO), an industrial robot is a multi-purpose, reprogrammable automatic control manipulator with three or more programmable axes, used in the field of industrial automation. In order to adapt to different uses, the mechanical interface of the last axis of the robot is usually a connecting flange, which can be equipped with different tools or end effectors. A welding robot is one that installs a welding tong or a welding (cutting) torch on the flange of the last axis of the industrial robot, enabling it to perform welding, cutting, or thermal spraying.

[0003] A welding robot consists of parts such as a welding power source, a wire feeder, and a welding torch. For an intelligent robot, there should also be a sensing system, such as a laser or camera sensor and its control device, etc. Most of the existing welding robots are fixedly installed and cannot adjust the height and angle during use according to the user's needs, resulting in poor practicability and inconvenience in use. Therefore, we have proposed a welding robot with a height adjusting device. Content of the Utility Model

[0004] The purpose of the utility model is to provide a welding robot with a height adjusting device. By adjusting the programming procedures of the connections of each robotic arm and then starting the device, first start motor four, which drives gear one to rotate through output rod four. Then, by adjusting the code, motor two records the movement trajectory, enabling motor two to adjust the specified height of robotic arm two upward or downward. Thus, the welding direction of the welding head fixed on the front of robotic arm two can be controlled. Subsequently, according to the start of motor three, with the drive of output rod three, the connecting block can drive the welding head to finely adjust the specified direction of the welding head. Thus, the adjustment of the height of the welding rotating shaft can be achieved, solving the problem that most of the existing welding robots are fixedly installed and cannot adjust the height and angle during use according to the user's needs, resulting in poor practicability and inconvenience in use.

Thus, the adjustment of the height of the welding rotating shaft can be achieved, and at the same time, in case problems occur during the long-term operation of the welding machine, it is convenient for the staff to repair.
