Description

Technical Field

[0001] This utility model relates to the field of welding equipment, specifically linear welding equipment. Background Technology

[0002] Automated welding refers to a welding process entirely controlled by mechanical equipment, requiring no human intervention. Welding parameters and paths are pre-set by a computer or other control system. It is highly efficient and suitable for mass production. Welding quality is stable and repeatable. However, it is less adaptable to complex welding positions and is generally suitable for welding standardized and simple structures.

[0003] For example, the patent with authorization announcement number CN219520966U discloses a linear welding device that effectively solves the problem that the lack of fixed clamping of the workpieces to be welded easily leads to a large gap between the two workpieces, resulting in poor welding effect. The device includes a worktable with support legs installed at the four corners of the bottom end, a clamping assembly installed at the top end of the worktable, a welding assembly installed at the top end of the worktable, a movable seat movably provided on the side, and clamping units installed at the top end of both the fixed seat and the movable seat, with a moving part installed at the bottom end of the movable seat.

[0004] The aforementioned patent activates the first motor on the fixed seat and the movable seat, causing the two clamping plates to come closer together and clamp the two workpieces. Then, the electromagnet is energized, and the movable seat moves the workpiece towards the other workpiece under the repulsive force of the electromagnet, making the two workpieces fit together and thus reducing the gap between the two workpieces, thereby facilitating welding. However, the disadvantage of the aforementioned patent is that it cannot fix the workpiece in the height direction, resulting in poor fixing effect.

[0005] Therefore, it is necessary to improve such a structure to overcome the above-mentioned defects. Utility Model Content

[0033] A chain fixing block 215 is also fixedly installed on the top of the welding gun mounting plate 204, and the chain fixing block 215 is fixedly connected to a section of the transmission chain 214.

[0034] When the welding torch moving motor 210 is activated, it can drive the transmission chain 214 to move, and the transmission chain 214 can drive the welding torch mounting plate 204 to move along the guide rail 203 through the chain fixing block 215.
