Abstract
Description
Technical Field
[0001] This utility model relates to the field of welding positioning technology, and more specifically, to a positioning device for the outer shell structure of a range hood. Background Technology
[0002] As a core appliance in modern kitchens, the range hood's outer shell structure is mainly composed of three types of metal components: the outer shell panel, the frame panel, and the cover panel. The overall structural strength, assembly precision, and surface smoothness of these components directly affect the final quality, lifespan, and user experience of the product. Currently, welding is one of the main processes for connecting these key components in the manufacturing of the range hood's outer shell structure.
[0003] Currently, in the manufacturing of some range hood shell structures, there is no dedicated positioning device during the welding of shell panels, frame panels, and cover plates. Positioning is primarily achieved through traditional manual visual alignment and handheld fixing, requiring 2-3 workers to work together. A welder then performs spot welding or continuous welding. However, manual operation not only makes the shell structure assembly process complex, time-consuming, and labor-intensive, but also, due to the lack of reliable positioning benchmarks, the shell panels, frame panels, and cover plates rely entirely on the worker's skill level. This leads to poor product dimensional consistency, inaccurate alignment, and a high error rate, resulting in quality defects such as gaps or incomplete welds in the welded range hood shell structure, affecting the product's structural strength and quality.
