Embodiment Construction

[0032] Such as Figure 1 to Figure 5 As shown, a welding manipulator 100 according to an embodiment of the present invention includes a feeding device 102 and a welding tongs 104 connected to the feeding device 102 .

[0033] Further, the feeding device 102 includes: a linear module 20 connected to the welding tongs 104 , and a rotary module 40 . The rotary module 40 includes a gear set rotary module 42 connected to the feeder 102 . The welding tongs 104 are connected and fixed on the gear set rotating module 42 .

[0034] Such as figure 1 and Figure 5 As shown, the gear set rotary module 42 includes a pair of intermeshing external gear slewing bearings 424 and a pinion 422 , and a power element connected to the pinion 422 . In this embodiment, for the convenience of arrangement and installation, the slewing support 424 is externally meshed with the pinion 422 . The power element connected to drive the pinion gear 422 includes a servo motor 421 and a reducer 423 connecte...

Abstract

The invention relates to a welding manipulator which comprises a feeding device and welding pliers connected with the feeding device. The feeding device comprises a linear module and a rotating module which are connected with the welding pliers; the rotating module comprises a gear bank rotating module connected with the feeding device by a slewing bearing; the welding pliers are fixed on the gear bank rotating module; the welding manipulator replaces a robot to move so as to carry out feeding by the linear module and the rotating module and is low in cost; by the linear motion of the linear module and the rotation motion of the rotating module, the high-accuracy positioning of a random space trace can be implemented in a mechanical stroke; the rotating module adopts the gear bank rotating module to carry out high accuracy rotation; the linear module implements high-accuracy linear transmission; when the linear module is linked with the rotating module in a multi-axis manner, the full-automatic welding of a resistance spot welding point on an automobile body in white can be implemented; the welding pliers are fixed and driven to rotate by a gear of the gear bank rotating module; the structure setting is ingenious; an additional connecting mechanism is simplified; and the high-accuracy feeding is implemented by gear transmission.

Description

technical field [0001] The invention relates to a welding device, in particular to a welding manipulator. Background technique [0002] At present, the mature body-in-white resistance spot welding technologies include manual spot welding, special plane multi-spot welding, robot spot welding, etc. [0003] In manual spot welding, the worker holds the spot welding tongs to weld the workpiece point by point. It has great flexibility and relatively low cost, but there are disadvantages such as inaccurate manual positioning, low consistency and appearance quality of solder joints, poor ergonomics of solder joints in special positions, and with the continuous rise of domestic labor costs, manual welding costs will also increase. [0004] Special machine multi-spot welding refers to a welding machine designed and manufactured for a specific workpiece, and multiple spot welding guns installed on it work at the same time. It is suitable for workpieces with dense distribution of so...
