Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
Referring to fig. 1, in an embodiment of the present invention, a straight seam welding arm mechanism in a tower includes a movable base 1, a support pillar 2, a transmission system 3, and a welding arm 4, wherein a through groove for a transmission shaft 33 to pass through is drilled on the support pillar 2; the welding arm 4 is connected to the other side of the support column 2 through a transmission shaft 33, and one end of the welding arm, which is far away from the support column 2, is connected with a welding gun connecting frame 41 through a bolt. The one end that welding arm 4 kept away from welder link 41 is fixed with balancing weight 5, and balancing weight 5 mainly plays the counter weight effect, and this kind of design is in order to prevent that welder from appearing the condition of rocking of "head is heavy foot light" in the rotation process. The other welding of balancing weight 5 has cylindrical arch, it has connecting rod 6 to articulate in the arch, the other end of connecting rod 6 passes through the threaded through hole of bolt and carriage release lever 21 and is connected. When the welding work is stopped, the connecting rod 6 can be fixedly connected with the moving rod 21 through a bolt, and the welding arm 4 can be fixed by utilizing the characteristic that the triangle has stability; when the welding work is started, the bolt for fixing the connecting rod 6 is removed.
