Description

Technical Field

[0001] The utility model relates to the technical field of vehicle pipe fitting production equipment, in particular to a welding robot for vehicle pipe fitting production. Background Art

[0002] Bicycles, also known as bicycles or bikes, are usually two-wheeled small land vehicles. People ride on the bicycles and use pedals as power. It is a green and environmentally friendly means of transportation. At the same time, when riding a bicycle, you need to manually support the handlebars of the bicycle. Bicycles contain many tubes. When producing bicycle tubes, the handles in the tubes need to be welded to improve the stability of the tubes when positioning. In order to improve the production efficiency of tubes, welding robots are used to assist in welding the tubes to improve the stability and efficiency of equipment welding.

[0003] During the processing of the welding robot, the welding device will be installed on the robot arm, and the robot arm will be installed on the base. After the angle and orientation of the welding device are limited by the robot arm, the welding device can be used to weld the vehicle pipe fittings. However, among common vehicle pipe fittings, the welding parts of the vehicle pipe fittings need to be circular or elliptical. Therefore, during the welding process of the vehicle pipe fittings, the welding angle of the robot arm needs to be adjusted to ensure the comprehensiveness of the welding device when welding the vehicle pipe fittings all around. However, during the rotation of the robot arm, in order to prevent the base from interfering with the movement of the robot arm, the robot arm needs to be kept in a forward tilted state during installation. The forward tilted robot arm will cause the pressure generated between the robot arm and the base to increase. When the increased pressure continues, it is easy to cause damage to the connection between the robot arm and the base. For this reason, we propose a welding robot for the production of vehicle pipe fittings. Utility Model Content
