Description

Technical Field

[0001] The utility model relates to the technical field of welding equipment, in particular to a high-efficiency automatic welding device for a floor fan column. Background Art

[0002] In the existing floor fan manufacturing process, welding the fan shaft is a critical step, directly affecting the product's stability, safety, and aesthetics. Traditionally, this process relies primarily on manual welding techniques, where operators use manual welders or semi-automatic welding equipment to perform the welding. However, this technology has several limitations and shortcomings in practice:

[0003] 1. The manual welding process is usually inefficient. Since the operation speed is limited by the operator's skills and physical strength, it takes a long time to complete the welding of a floor fan rod, which is difficult to meet the needs of large-scale production.

[0004] 2. The inconsistency of manual operation makes it difficult to standardize welding quality. The different skill levels, experience and working conditions of each operator may lead to differences in welding results, which poses a challenge to maintaining consistent product quality in mass production.

[0005] 3. Manual welding cannot ensure the consistent quality of each welding. The formation of the weld is affected by many factors, such as welding speed, angle, heat input, etc. If you are not careful, problems such as uneven welds and welding defects may occur.

[0006] 4. The particularity of shaft welding: As a shaft component, the welding process of a floor fan shaft is particularly troublesome. Welding is required around the circumference of the shaft, which not only requires high technical skills of the operator, but also makes it difficult to ensure flexibility and accuracy during the welding process.
