Technical Field

[0001] The utility model relates to the technical field of welding guns, in particular to a welding gun mechanism with a gripper. Background Art

[0002] At present, the welding field mainly includes manual welding and robot welding. Manual welding is mainly used in the welding of small batches of single-piece welding machines or super-large equipment. It can cope with complex welding environments and cannot be replaced by many robot welding. However, in the welding of small workpieces that require batches, robot welding can solve many problems such as human resources, personal safety, production costs, and production efficiency.

[0003] At present, in the existing technology, the welding robot connects a welding gun to the output end of the robot arm, and welds the workpiece positioned on the fixture through the multi-joint movement of the robot. However, in terms of work content, the robot only completes the welding work. Because manual or other robots are required to clamp and position the workpiece before or after welding, the utilization rate of intelligentization is not high. In addition, when welding special parts of some special workpieces, the welding robot cannot reach the welding gun at that part because the flexibility of the welding robot does not meet the requirements, making it impossible to weld.

[0004] Therefore, it is particularly important to improve the existing welding gun mechanism with a gripper, design a new welding gun mechanism with a gripper to solve the above technical defects, and improve the practicality of the overall welding gun mechanism with a gripper.

At the same time, due to the linkage of the linkage rod 606, the moving blocks 605 are brought close to each other, so that the clamping rods 607 are brought close to each other, so that the object to be welded is clamped and positioned.

[0028] Among them, see Figure 1 , Figure 2 and Figure 3 In this embodiment, the interiors of the vertical track 602 and the horizontal track 603 are interconnected, a rotating column is installed on the top of the clamp rod 607, the rotating column extends to the interior of the linkage rod 606, the clamp rod 607 is connected to the linkage rod 606 through the rotating column, and the design of the vertical track 602 and the horizontal track 603 being interconnected greatly improves the linkage, and the clamp rod 607 can achieve highly smooth movement with the help of the rotating column.

[0029] Furthermore, please see Figure 1 , Figure 2 and Figure 3In the present embodiment, a receiving groove 608 is provided at one end of the outer frame 601 away from the clamping rod 607, and a telescopic cylinder 609 is installed inside the receiving groove 608.

Through the design of the telescopic cylinder 609, the output end of the telescopic cylinder 609 accurately controls the movement of the driving plate 604, so that the driving plate 604 moves backward inside the vertical track 602, thereby realizing that the linkage rod 606 drives the moving block 605 to move inside the horizontal track 603.
