Description

Technical Field

[0001] The utility model relates to a welding manipulator, in particular to an efficient manipulator welding unit. Background Art

[0002] With the acceleration of the industrialization process and the development of the manufacturing industry, welding equipment, as a key production tool for realizing the welding process, plays an important role in various industries. The structure of the welding equipment is directly related to the efficiency and quality of the welding operation. The current welding equipment on the market generally includes a welding manipulator and a workpiece fixture. For some complex and large workpieces that need to be assembled after welding, when using such welding equipment for welding, when a part of the position is welded, the welding manipulator needs to stop welding and wait for the assembled part of the workpiece, and then perform welding on other parts. During this period, there is a certain waiting time for assembly, and the welding manipulator stops working, resulting in a reduction in the welding work efficiency and an increase in the production cycle; moreover, it cannot perform full-round automatic welding, and manual positioning and flipping methods need to be used to flip and adjust the workpiece, which is time-consuming and laborious, with low work efficiency, and is prone to part deviation, resulting in welding errors and affecting the welding quality. Content of the Utility Model

The positioner includes a vertical rotation mechanism, a horizontal rotation mechanism is arranged on the vertical rotation mechanism, and the horizontal rotation mechanism is used to place the workpiece.

[0005] In the aforementioned efficient manipulator welding unit, two positioners are adopted, and the two positioners are respectively located on both sides of the welding manipulator.

[0006] In the aforementioned efficient manipulator welding unit, the vertical rotation mechanism includes a pair of bottom frames, a first servo motor is arranged on one of the bottom frames, a flipping seat is rotatably connected between the two bottom frames, and the flipping seat is driven by the first servo motor and a first reduction gear; the horizontal rotation mechanism includes a second servo motor located in the flipping seat, the second servo motor is connected with a turntable through a second reduction gear, and the turntable is used to place the workpiece.
