Description

Technical Field

[0001] The utility model relates to a forging industrial welding robot, belonging to the technical field of industrial welding. Background Art

[0002] A welding robot is an industrial robot engaged in welding. A welding robot is an industrial robot that has a welding clamp or welding gun installed on the end shaft flange to enable it to perform welding, cutting or thermal spraying. The welding robot is composed of an operating table, a welding structure, a feeding device, a fixing device and other structures. The feeding device is used to transport the product to be welded to the table top of the operating table, and the fixing device is used to fix the product. Subsequently, the welding structure is opened to perform the welding operation on the product.

[0003] The existing patent number is CN220094627U, which is a forging industrial welding robot. This device uses the structural design of the adjustment device to open the No. 1 small motor inside the structure box, and the output shaft drives the No. 1 gear to rotate. Under the action of the fixed rod and the No. 3 gear, the action tube drives the action rod to rotate accordingly, and then the No. 2 small motor is turned on, and the output shaft drives the No. 2 gear to rotate. Under the action of the gear teeth inside the structure groove, the moving rod moves along the through hole, and under the cooperation of the sliding hole and the sliding rod, the moving rod drives the structure base to move accordingly, and applies a force to the telescopic cylinder, so that the welding head reaches the specified welding position, realizing the product at multiple angles. The welding function reduces the assembly line of welding operations and improves work efficiency. However, this device can only weld small welded parts by rotating the welding head when in use. For larger workpieces, they not only need to be manually carried and supported on the welding table during welding, but it is also difficult to adjust the height according to the welding position, thereby reducing the convenience of welding processing. Moreover, during welding, although welding of different shapes can be performed only by rotating the welding head, it is difficult to perform circumferential welding around the welded part, and the workpiece needs to be manually turned over, which is dangerous and affects the one-time forming welding processing of the welded part.
