Description

Technical Field

[0001] The utility model relates to the technical field of welding workstations, in particular to a double-machine cooperative welding workstation. Background Art

[0002] In the process of processing various parts, many of them require the use of welding technology. Especially when the more parts to be assembled or the more complicated the production of the parts is, the more welding points there will be in the entire component, such as plane welding, side welding, etc. Therefore, two independent welding robot arms will be used to work together to improve the overall welding work efficiency.

[0003] A dual-machine collaborative welding workstation is disclosed in the patent number CN201922292143.5, which relates to the field of welding workstations and aims to solve the problem that a single welding robot cannot meet the processing requirements when welding complex parts with a large number of welds and complex positions. The dual-machine collaborative welding workstation is symmetrically arranged, including a welding motor, a cooling water tank, a control cabinet, a welding fixture, a grinder, a welding robot, an operation panel, a slide, a workbench, a welding station, and a loading and unloading station. The welding motor is installed on the workbench, a cooling water tank is installed on the right side of the welding motor, a control cabinet is installed on the right side of the cooling water tank, the welding robot is installed below the grinder, the operation panel is installed at the bottom of the workbench near the left side, the slide is arranged between the welding station and the loading and unloading station, and the welding station is located above the loading and unloading station. The welding of complex parts and multiple stations can be completed synchronously through the collaborative cooperation of the dual machines to improve work efficiency.

[0004] The above device has certain shortcomings when in use: two welding robots are installed on the left and right sides of the top of the workbench for symmetrical welding to cover as many welding points as possible. Since the position of the welding robot is fixed, the welding positions of different parts are different. When the mechanical arm of the welding robot cannot move to the welding position, a welding dead angle is formed. When the welding robot needs to be moved at this time, it may be impossible to operate.

[0005] To this end, the utility model provides a dual-machine collaborative welding workstation to solve the above problems. Utility Model Content
