Description

Technical Field

[0001] This utility model relates to the field of welding positioner technology, and in particular to a welding positioner with high stability. Background Technology

[0002] A welding positioner is an auxiliary device used in welding work. It can adjust the position and angle of the workpiece as needed to facilitate welding operations. A welding positioner is usually composed of a worktable, a rotating mechanism, a lifting mechanism, and a control system. The worktable is equipped with clamps or chucks for fixing the workpiece. The rotating mechanism can drive the worktable to rotate in the horizontal or vertical direction. The lifting mechanism can adjust the height of the worktable. The control system can control the operation of the rotating mechanism and the lifting mechanism.

[0003] A highly stable welding positioner is proposed in patent publication number CN220592127U. This patent includes a base, a vertical rotary bearing, a driven connecting L-plate, a horizontal mounting plate, an active connecting L-plate, a vertical rotary reducer, a vertical rotary motor, a base box, a horizontal rotary reducer, a horizontal rotary motor, a mounting frame, and a connecting plate frame. The advantages and positive effects of this invention lie in its simple structure, ingenious design, and reasonable layout. It addresses various problems existing in traditional positioners during operation by designing a special structure that allows the workpiece held by the fixture to be modified... By changing its spatial position and orientation, it facilitates welding operations by welding robots. Simultaneously, its reducer is a hollow reducer, allowing various data cables to pass through its cavity, thus minimizing the cable routing distance and difficulty, and effectively preventing cable twisting during operation, ensuring stable and accurate data transmission.
