Description

Technical Field

[0001] The utility model relates to the technical field of upper frame welding, in particular to an upper frame welding structure for a harvesting machine. Background Art

[0002] A harvester is a machine that harvests crops in one go. It harvests and threshes the grains simultaneously, collecting them in a storage bin before transporting them to a transport vehicle via a conveyor belt. Harvesting can also be done manually, with rice, wheat, and other crop stalks spread out in the field, where they are then picked up and threshed by a grain harvester. Crop harvesting machines harvest the grains and stalks of cereal crops like rice and wheat. These include harvesters, reapers, balers, combine harvesters, and threshers.

[0003] During the welding process, a welding positioning fixture can accurately position and clamp the workpiece, thereby facilitating the welding operation and ensuring the accuracy of the welded structure. With the acceleration of industrialization, automatic welding robots are widely used in the manufacturing process of larger products and equipment such as vehicle parts and electrical boxes. For example, the welding positioning fixture disclosed in Chinese patent authorization announcement number CN206543966U only enables the automatic welding robot to weld the welds on the front of the harvester bracket during the welding process. The welds on the back require the harvester bracket to be removed from the fixture and then manually repaired. This makes it difficult to fully utilize the welding robot, resulting in low welding efficiency and reduced production efficiency.

[0004] For this purpose, it is necessary to provide an upper frame welding structure for the harvesting machine. Utility Model Content
